Causes of Absenteeism
Absenteeism is caused by many factors as such as:
1. Phobic Adolescence: During this stage in the growth of a teen, there is a lot of fear developed as a result of physical changes of the body for example growth of pimples, turbulent emotions e.t.c. This scares teens away from school.
2. Lack of Interest: Students could be lacking interest in the study, which could be as a result of content that is difficult for them to grasp hence pushing them away from school.
3. Teacher approach: The approach used by teachers may not be understood by the student and this could lead them to lose interest in school. Punitive attendance policy plays a big role in absenteeism too.
4. Pamperness from the family: Students who get excessive pocket money from their families are most likely to absent themselves from school since they need time to spend the money.
5. Private Couching: Flexible private couching encouraged by some parents could drive a number of students away from the conventional school timetable.
6. Diseases: Some diseases like asthma which requires attention and care as well as an environment that is warm and not dusty could make students remain home.
7. School Infrastructural Facilities: Lack of libraries, sports facilities is a hindrance to attendance of school among students.
8. Entertainment: Accessibility of entertainment facilities like cinemas could divert attention of some students from school.
Absenteeism can lead to depression and also result in poor quality of education as a result of time lost while being away from school. It could also lead to moral degradation that leads to drug abuse, early pregnancies and unruly behavior.
Absenteeism can be remedied by providing adequate co-curricular activities to students. It could be curbed by creating of clubs and societies to keep students busy when they are out of class. Schools should strive to have up to date learning facilities like libraries as well as sporting facilities to make students enhance student retention.
The Alchemist
Thoughts

     The books also talked about the connection of everything in this universe. We are all connected. We are all one. The universal soul talks to us by way of our intuitions. We should always remember that what we desire to have and the desires of the universe and the force that bind them is always positive. Like what the book says. “When you want something, all the universe conspires in helping you to achieve it.”

   The book teaches the very basic thing to be always optimistic. The book looks into the mysteries and realities of our life, which we never pause to ponder. Like the alchemist who can turn an ordinary rock into a gold, if we follow our own calling, we can also turn our ordinary lives into something unimaginable.

Insights
  The first lesson that I learned was that dreams don't go anywhere unless one pursues them.  Santiago could have let his dream die, but instead he persevered and took action to try and the treasure.
     The second lesson that I learned was that change is good.  The merchant never could bring himself to travel or accomplish more because he was afraid of change.  It is through embracing  change that we become who we are and shape our destiny.
     The last lesson that I identified is that the journey itself is the prize.  Life is a journey.  Santiago never found his physical treasure but he gained insight, and wisdom, a new love, and self-satisfaction through his journey.  It led him back home but he had fulfilled his dream through his journey.  He had met people and seen things that he would never have seen if he stayed home watching the sheep.

Symbolism 

     There is Santiago's sheep. They represent Santiago's blindness to his own destiny, his own quest. Like the sheep he mindlessly does the same thing everyday.
     There is of course Alchemy. The ability to turn base lead into gold. The symbolism comes in when Santiago follows his quest and learns he can turn (spiritually) what he already has into something beyond gold.

http://parojinogalf.blogspot.com/THE ALCHEMIST 

Author: Paulo Coelho

Name of publisher: Harper Collins Publisher 

Year of Publication: 2005

Genre: Novel

INSIGHT:

After reading The Alchemist one is able to reflect on the journey that life has handed him.  In the book Santiago has a dream about a treasure.  He keeps his mind focused on going after the treasure.  When he does start to lose sight of accomplishing his dream, he has people along the way and omens which guide him.
The first lesson that I learned was that dreams don't go anywhere unless one pursues them.  Santiago could have let his dream die, but instead he persevered and took action to try and the treasure.
The second lesson that I learned was that change is good.  The merchant never could bring himself to travel or accomplish more because he was afraid of change.  It is through embracing  change that we become who we are and shape our destiny.
The last lesson that I identified is that the journey itself is the prize.  Life is a journey.  Santiago never found his physical treasure but he gained insight, and wisdom, a new love, and self-satisfaction through his journey.  It led him back home but he had fulfilled his dream through his journey.  He had met people and seen things that he would never have seen if he stayed home watching the sheep.
However, Santiago now needs to earn some money in order to get across the great desert that stands between him and the Great Pyramids, where his treasure lies. He finds work at the shop of a crystal merchant. Here he learns Arabic, so that he may converse with the merchant, as well as with the customers. He brings about many improvements to the store, with a creative outflow of ideas that ultimately increases business exponentially for the merchant. Another insight is thus brought to Santiago, that “everybody has a creative potential and from the moment you can express this creative potential, you can start changing the world.” By generating and implementing new ideas in the crystal merchant’s shop, Santiago has brought not only more business, but inspiration to the merchant’s life and thus changed the world in this small yet profound way.



Thoughts:

 So I just finished reading The Alchemist by Paulo Coelho, and thought I’d share my thoughts. I’d never heard of the book, or indeed the writer, before receiving the book as a gift a few weeks ago (though I have since come to know that the author is quit prolific), so my opinions of the novel are based solely on the novel, having had no predispositions or biases before reading it. Anyway, lets get to it.
The Alchemist tells the story of a young Andalusian shepherd named Santiago, content in his rambling life until a recurring dream incites in him a longing for adventure. Santiago sells his sheep travels to north Africa in search of treasure and the fulfillment of his destiny.
I have mixed feelings about The Alchemist. As I said, going into the Alchemist I really didn’t know what to expect. The cover blurb sounded intriguing, and the many quotes from critics sampled on the first two pages spoke of a moving novel full of great wisdom and inspiration. Having now finished the book, I will agree that it does contain a good amount of wisdom, and it is inspirational (and on a few occasions actually quite witty), but I’m not sure how I feel about it as a novel.
The actual story of the book is good, and the ending (I won’t spoil it here) was rather more satisfying and surprising than I’d expected. However, the execution of said story, to my tastes at least, feels a bit simplistic and, with the exception of the aforementioned ending, predictable. Santiago’s journey is one of personal discovery, and the lessons he learns about life and happiness and finding your way in the world are all beautiful and uplifting, but they’re hardly new, and to someone such as myself who’s grown up hearing similar “you can do anything you set you mind to” and “follow your dreams/heart/talent/calling/destiny” type messages, Santiago’s ultimate success feels like a foregone conclusion. Indeed, the novel establishes such a feeling of positivity so early on that I could never really doubt in Santiago’s abilities, or find his struggles, while relatable, particularly engaging.
I also don’t quite know what to make of the characters. On the one hand most of them do feel quite vibrant and real, but at the same time they can be somewhat flat. For example, at one point in the novel Santiago meets and subsequently works for a crystal merchant (crystal as in glass, not the pretty shiny stuff what comes outta the ground) who has so many real, understandable human elements, but is used by the author to make a point about giving up on one’s dreams. What makes this particular character’s purpose so clear, I think, is that way it is conveyed. While the narrative or the protagonist could have made subtle or even blatant observations about the merchant to relay this message; instead we have the actual character himself telling us about his failure to realize his dreams, even going so far as to explain why he did so.
Symbolism:http://parojinogalf.blogspot.com/

An Analysis of Mirage Symbolism In The Alchemist Paulo Coelho’s The Alchemist tells the story of Santiago, a young shepherd living in an abandoned church in a small Andalusian town, who is stripped of his comfortable and safe lifestyle after an encounter with Melchizedek, an Islamic king who tells him of his “Personal Legend”. Melchizedek points Santiago in the direction of his treasure only after taking one-tenth of his money, giving him two stones, and a lesson on reading omens.


Throughout his journey, Santiago meets new friends, has everything stolen from him three times, and travels the vast and unknown Sahara Desert all while achieving personal growth and an understanding of his life’s meaning. His journey leads him to an Oasis where he meets the alchemist, a man who will lead him on to the pyramids of Egypt. When Santiago finally completes his journey and arrives at the pyramids, he is beaten by soldiers and ironically told where the treasure is truly hidden: buried beneath a tree at an abandoned church, the exact spot where he had started.

Coelho masterfully works symbolism into The Alchemist to give the reader a direct picture and deeper understanding of his piece. These symbols allow the reader to gain valuable insight into the piece through background knowledge and relations to the symbol itself. One example of symbolism in The Alchemist is mirages, or hallucinations. This symbol is not used in the way a typical reader would think. Instead of meaning a picture that one sees in the extreme heat, it is used to represent a vision or aspiration.

Although the term mirage is mentioned only once in the novel, it is symbolized throughout by Santiago’s struggle to obtain his treasure. His hardships in traveling give the reader a sense that the treasure itself may be a mirage, something Santiago is only dreaming of but may never physically reach. Coelho uses two separate meanings of the word mirage. The literal definition word mirage is used the one time that it is mentioned and is understood to mean a vision. Santiago is watching hawks flying through the sky when an adverse move by one bird causes him to see a sign.

Suddenly, one of the hawks made a flashing dive through the sky, attacking the other. As it did so, a sudden, fleeting image came to the boy: an army, with its swords at the ready, riding into the oasis. The vision vanished immediately, but it had shaken him. He had heard people speak of mirages, and had already seen some himself: they were desires that, because of their intensity, materialized over the sands of the desert. But he certainly didn’t desire that an army invade the oasis. At this point in the novel, Coelho is using mirage in the literal sense of a vision seen in the desert.
Although Santiago sees it is a sign of the future and acts on this thought, the meaning of the word in this sense remains the same. Coelho also inadvertently compares Santiago’s entire journey as a mirage in itself. There are many times throughout the plot where it seems Santiago has almost reached his treasure or has made progress only to find a block in the road or a digression he must make. Although the reader may not make the connection during the first read, it is evident that the story line mirrors that of a mirage as Santiago seems physically unable to reach his treasure with ease.

The first instance of such struggle comes early in his journey. Santiago sold his sheep and was traveling through Tangier when he stopped in a bar. There he meets and strange man who, for the right price, offers to take him to the pyramids claiming they “could get to the Pyramids by tomorrow”. Santiago allows himself to trust this man and lets him hold his money, the entirety of his possessions. The man leads Santiago through the plaza, a maze of people, vendors, and animals and, eventually, Santiago loses the stranger and all his money. This is the first time Santiago’s Personal Legend could be perceived as a mirage.

Like a hallucination to a thirsty and tired desert traveler, this event gave Santiago happiness and hope only to leave him without his proverbial water and shelter. After being promised a guide to the pyramids and a short travel period he was instead left alone and without money. What had minutes beforehand seemed like a perfect way to his treasure was now only an empty promise. Soon after, Santiago is forced to work for a crystal merchant in the hopes of replacing his lost money and continuing on his quest. He works for the merchant for eleven months and during this time, continues to think less and ess of his Personal Legend. He becomes skilled in this practice and begins to work towards instead, replacing his flock of sheep and returning to his past lifestyle. During this time, Santiago perceived reaching the pyramids as an impossible feat claiming “Egypt was now just a distant dream for him” and that, like a mirage, it would always be just out of his reach. In this way, Coelho shows that Santiago’s morale is lessening. The more that he stays at the crystal shop, the more he sees his treasure as a mirage instead of a physical object.

Not only can the boy’s journey be related to mirages, so to can his relationship with Fatima. He first meets her at the oasis by the water well. They next day he returns and tells her that he loves her. From there he begins to tell her of his life as a shepherd and his search for treasure. Fatima listens patiently for a month and then finally tells Santiago her true feelings for him. She explains that she is a woman of the desert and that, since she is a woman of the desert, she is used to watching husbands leave. She explains how she is glad to let him go and wish for his safety until he returns, as it is something his must do.

Santiago heeds her advice and continues on his journey, always thinking back to Fatima and the oasis, yearning to be with her. Coelho once again presents an event that can be compared to a mirage in this relationship. Santiago finally finds the woman he claims to love and just as he is getting close to her, she sends him off, away from what he desires. Santiago uses this relationship that is at the tip of his fingers as motivation to reach the end of his Personal Legend and return to Fatima with the treasure he has been searching for.

Perhaps the largest and most prominent example of and event relating to a mirage would be when Santiago finally reaches the pyramids. After the hardships he encounters along his way, which include being stolen from twice, being stuck in the midst of a war, and having to turn himself into the wind, he finally reaches Egypt where his treasure is fated to be held. He praises God for leading him along his Personal Legend and begins to dig when he is approached by several men who command him to keep digging, as they were to take his gold.

When Santiago found nothing in the ground, the men beat him and stopped only after he explained that he was led there by a dream. The soldiers leave but not before the leader explains a recurrent dream that he had. He told Santiago that his dream instructed him to “travel to the fields of Spain and look for a ruined church where shepherds and their sheep slept. In my dream, there was a sycamore growing out of the ruins of the sacristy, and I was told that, if I dug at the roots of the sycamore, I would find a hidden treasure”.

This perhaps is the most ironic part of the story, as well as the most relevant to the mirage symbolism that is prevalent throughout the story line. Through the entirety of his journey, he is told that his treasure lies at the pyramids. He struggles to cross the desert and find his way there. When he finally reaches the place that seemed almost impossible to find, he is beaten and told through another person’s vision that his treasure lays in the fields of Andalusia, the exact spot where he started. It seemed that he was so close to his treasure, just one grain of sand away when suddenly he is told how far he truly is from obtaining it.

This mirage reference gives the reader a sense of humor and knowledge that, the whole journey was made up for the purpose of personal growth. It gives the reader the sense that, while Santiago had always been right on top of the treasure and never knew, the journey and spiritual and personal growth was the real treasure Santiago obtained. When Santiago finally finds his treasure from the same tree he had previously slept under, the reader is given a final sense of relief that he has finally found the item that had always been just out of reach.

Coelho uses these examples of symbolism and more to create an overlying relation of Santiago’s journey to that of a mirage. While this is not a traditional style in which a symbol is used and may not be noticed by a reader their first time reading the book, it is a prevalent relation that adds depth and character to the book. Even though the word mirage is only mentioned one time, a reader will be able to connect Santiago’s struggle in traveling and in his interpersonal communications as a relation to mirages. Without this relation, an element of the novel’s plot would be lost and readers would have nothing to compare his struggles to.

Not only does the mirage relation give the reader a physical image to compare with his quest, it also ties the journey back to the setting, the Sahara Desert. This adds yet another layer to the story line that previously claimed everything is connected by the “Soul of the World”. Coelho masterfully works this overlaying symbol into his novel to add depth and character to a story and to give the reader an overall moral; to never give up on your dream, even when it seems as if it will always be physically unattainable.
This moral is illustrated by Santiago’s determination in finding his treasure and returning to Fatima at the oasis, even when so much had already gone wrong on his quest. It describes how, if a person maintains their intended path and listens to their heart, they will have treasure beyond their dreams, find personal and spiritual growth, and be truly happy.

THE EIFEL TOWER GOES GREEN
This was one of the unique challenges that UGE International faced as the manufacturer of the turbines. “We worked very closely with the general contractor [Bateg, a subsidiary of Vinci Construction France] so that we could adhere to all the laws of the tower,” says Jan Gromadzke, UGE’s project engineer. That includes no welding, drilling, or using any lifting equipment on the tower.

SCIENCE ''What if the world lost oxygen for 5 seconds?''-Designericle Mendez Soronio Jr.




Oxygen may not be the main constituent of the Earth’s atmosphere, but its role in the survival of many forms of life elevates its significance. No one can live without sufficient quantity of food, water and oxygen. Of the three, oxygen is by far the most important and urgently needed. Have you ever imagined what if oxygen from the Earth was lost for 5 seconds?



Everyone at the beach would get sunburns. Ozone is molecular oxygen, and blocks the majority of UV light. Without it we are toast.





  • The day-time sky would get darker. With fewer particles in the atmosphere to scatter blue light, the sky would get a bit less blue and a bit more black.

  • Every internal combustion engine would stall. This means that every airplane taking off from a runway would likely crash to the ground, while planes in flight could glide for some time.
    All pieces of untreated metal would instantly spot weld to each other. This is one of the more interesting side effects. The reason metals don't weld on contact is they are coated in a layer of oxidation. In vacuum conditions, metal welds without any intermediate liquid phase (Cold welding).

  • Everyone's inner ear would explode. As mentioned, we would lose about 21% of the air pressure in an instant (~ from sea level to 2000m elevation), so expect some serious hearing loss.
  • Every building made out of concrete would turn to dust. Oxygen is an important binder in concrete structures (really, the CO2 is), and without it the compounds do not hold their rigidity.
     

  • Every living cell would explode in a haze of hydrogen gas. Water is 88.8% oxygen; without it the hydrogen turns into gaseous state and expands in volume.Molecular weight of Water
    The oceans would evaporate and bleed into space. As oxygen disappears from the oceans' water, the hydrogen component becomes an unbound free gas. Hydrogen gas, being the lightest, will rise to the upper troposphere and slowly bleed into space through Atmospheric escape.











  • Everything above ground would immediately go into free fall. As oxygen makes up about ~45% of the Earth's crust and mantle, there is suddenly a lot less "stuff" beneath your feet to hold everything up.


  • What would happen if the amount of oxygen in Earth's atmosphere was doubled instantly?

    Drones


    Drones or Unmanned Aerial Vehicles, are air crafts that can be navigated without a human pilot riding. Drones can be navigated by the controlling it from the ground , using a controllers or also known as GPS tracking system. Through advance technology, dome of these drones are now equipped with cameras that allow the user to record and take pictures. As of today, Drones are very useful in many aspects of life. Here are some of its best uses:


    Aerial Inspections

    Companies and governments all over the world are getting in on the drone action. Drones, are perfectly suited for the purposes of aerial inspections. We’re talking about bridge and building safety inspections that both government engineers and private contractors are continually tasked to carry out.A lot of drone manufactures have created crafts for almost every expected situation of human life like for industrial inspections, aerial photography, agricultural assessments and research and terrain mapping.


    Saving Lives

    Drones are sure amazingly efficient at taking lives, just look at the examples in those military operations and rescue operations. Into more futuristic terms, if drone developing companies such as Zipline, Matternet and Flirtey can overcome such barriers with their technologies, where they could advance their technology more, then drones could help overcome delivery challenges, like virus outbreaks that have are attacking the humanity, it could help spread the vaccine, the vaccine world for decades.


    Transportation

    There should be no doubt that drones are the future. From their potential to do excellent and fast aerial inspection, surveillance, entertainment in the form of racing and some “transportation”. drones could transport medical supplies or any help to those who are stranded or in a emergency situation.


    Drones are most likely here to stay with us. Drones is the face of the future,

    Technology


    Technology




    The history of technology is the history of the invention of tools and techniques and is similar to other sides of the history of humanity. Technology can refer to methods ranging from as simple as language and stone tools to the complex genetic engineering and information technology that has emerged since the 1980s


    "TECHNOLOGY'



    What is Technology? 

    Technology ("science of craft", from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia[3]) is the collection of techniques, skills, methods and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. Technology can be the knowledge of techniques, processes, etc. or it can be embedded in machines, computers, devices and factories, which can be operated by individuals without detailed knowledge of the workings of such things.

    -Wikipedia 

    Technology also is a helpful thing in us specially in our daily communication because it is our tool or weapon to express our selves more and to be more informative to other people as well. Technology may lead us to distraction specially in our studies but it also helps us more to widen our knowledge and vocabulary in life.

    -Faith

    In today's world where just about everything is more convenient and accessible due to the advances in technology across the world but let us balance what is the real help of having technology in us. 


    What are the Advantages and Disadvantages?


    As a student I can see/observe that there are Advantages and Disadvantages of using Technology.

    One of the Advantages is that:


    Technology help us in a way that simply checking the weather and stay updated on any situations that can affect us. 
    Cell phones helps us to stay connected to our families and be updated in there daily activities and to be informed in any bad possibility that may happen. 
    On making your school projects or assignments its more easy to get information in the internet. 
    Busy parents are able to pay bills and bank online. 


    There are many ways technology is helping us in our daily lives.. But wait, There are also Disadvantages that we forget to see and this are the following:

    One of the disadvantage i observe is that the lost of art in conversation, because people always depend in the technology they may forget the beauty of talking to someone in personal because they always relay in the technology. 
    The cyber bullying. Giving students access to anonymous accounts and endless contacts avenues can only lead to trouble specially in our world today. 
    A major distraction. Though some student use the technology in a good way but there are also some of them are using it in a wrong way that lead to distractions to there studies. 
    In using a technology always we also spent more money in buying a load or repairing our gadgets and paying billls to the internet connection. 


    -----------------

    The number one benefit of information technology is that it empowers people to do what they want to do. It lets people be creative. It lets people be productive. It lets people learn things they didn't think they could learn before, and so in a sense its all about potential :) 

    Thank you for reading :) Godbless!

                                                                          BIOLOGY









    Biology is a natural science concerned with the study of life and living organism, including their structure, function, growth, evolution, distribution, identification and taxanomy. Modern biology is a vast and eclectic field, composed of many branches and subdiscipline. However, despite the broad scope of biology, there are certain general and unifying concepts within it that govern all study and research, consolidating it into single, coherent field. In general, biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the synthesis and creation of new species. It is also understood today that all the organisms survive by consuming and transforming energy and by regulating their internal environment to maintain a stable and vital condition known as homeostasis.
    Sub-disciplines of biology are defined by the scale at which organisms are studied, the kinds of organisms studied, and the methods used to study them: biochemistry examines the rudimentary chemistry of life; molecular biology studies the complex interactions among biological molecules; botany studies the biology of plants;cellular biology examines the basic building-block of all life, the cell shysiology examines the physical and chemical functions of tissues, organs, and organ system of an organism; evolutionary biology examines the processes that produced the diversity of life; and ecology examines how organisms interact in their environment.



    Lynn White began his career as medieval historian focusing on the history of Latin monasticism in Sicily during the Norman Period but realized the coming conflict in Europe would interfere with his access to source materials. While at Princeton he read the works of Lefebvre des Noëttes, and Marc Bloch. This led to his first work in the history of technology, "Technology and Invention in the Middle Ages" in 1940.


    Noettes was a retired French cavalry officer who made his hobby the history of horses. He wrote that the utilization of animals in antiquity was inefficient because the ancients were limited by the technologies of their period, specifically the lack of horseshoes and a bad harness design. White expanded Noettes’ conclusions into a thesis of his own that encompassed the relationship of the newly realized efficient horse and the agricultural revolution of the time.



    WELCOME TO THE HUNGER GAMES.

    We all have that friend who occasionally runs on a cool 700 calories a day for a week so they can ~lose weight fast~ or whatever.



    And, OK, sometimes you are that friend.


    That’s a crash diet. As in, it’s pretty much bound to crash and burn.



    A crash diet is essentially a very restrictive meal plan that’s unsustainable for the long term, says Darcy Johannsen, Ph.D., R.D., assistant professor at Pennington Biomedical Research Center. It’s usually about severely restricting your calories — like cutting back to 1,000 or even as low as 500 calories per day. Or sometimes a crash diet is all about a juice cleanse or just eating one or two foods for a week. The length of time differs from diet to diet, but they always come with an end date.


    Here’s the thing: Crash diets can actually wreak havoc on your body, not to mention your general disposition (because, hangry). Here are nine reasons you should probably never do them again:

    1. Your metabolism slows WAY down, so you suck at burning calories.



    “When you limit calories so dramatically, your body goes into starvation mode and your metabolic rate plummets,” says Johannsen. Your body isn’t sure when it’s going to get fed again, so it does everything it can to conserve energy. So not only are you burning fewer calories doing normal activities (like digesting, standing, walking), but you’re also just moving less because you have less energy.

    2. And then you start to burn off muscle

    “If you’re being very restrictive with calories, you’re not just burning your fat as fuel,” says Johannsen. “You’re going to burn lean tissue, as well,” which is mostly muscle. In the first few weeks of your crash diet (which is about all they last anyway), about half of the fuel you’re burning comes from fat stores, while the other half comes from lean tissue mass (i.e., your biceps).

    3. You’re hungry ALL the time.









    Maybe it’s because all you’ve eaten today is an apple, or maybe it’s because your levels of the hormone ghrelin go up substantially when you’re in starvation mode, explains Johannsen. This hormone revs up your appetite and makes you want to eat everything, so it’s basically a vicious cycle that you cannot win.

    4. You become kind of a monster.



    And not just because everyone is eating cheeseburgers while you’re eating lettuce and lemon juice. “When people go on crash diets, there are changes in the neural networks and brain activity that make you very cranky and irritable,” says Johannsen. This is also anecdotally confirmed by everyone around you.

    5. Moving at all sounds like a chore.



    Thanks to decreases in your thyroid hormone and epinephrine (the hormone and neurotransmitter better known as adrenaline), you’re physically and mentally exhausted. “You basically have to fight to be active,” says Johannsen.

    6. Your sympathetic nervous system gets lazy.



    This can make you feel colder all the time, slow down your heart rate, or produce a drop in blood pressure that could even cause you to pass out.

    7. You miss out on major nutrients.


    On most crash diets, it’s hard to ensure that you’re getting enough protein, fiber, amino acids, calcium, iron, vitamin B12, and all that other good stuff that your body needs on a daily basis. Without these, lots of things can suffer — like your bones, cognitive function, blood cells, and more, says Johannsen.

    8. OK, sure, you’ll probably lose weight. BUT keeping it off is no guarantee.



    “If you really adhere to this, you’re going to lose weight because your calorie expenditure is far exceeding your intake,” says Johannsen. But whether or not you’ll gain it right back is up for debate (except, yeah, you probably will). A lot of people overdo it after a strict diet and end up gaining everything back immediately, says Johannsen.


    This could be related to your levels of the hormone leptin, which drop when you lose a lot of weight in a short period of time. And some research suggests that a larger decline in leptin levels is associated with regaining the weight back, says Johannsen.

    9. And post-crash… no one’s totally sure what might happen.






    Unfortunately, the research isn’t as clear when it comes to what happens after your crash diet, says Johannsen. For instance: Why do some people gain the weight back and others don’t? And what about your hormones and insulin sensitivity? Here’s what ~could~ happen, based on what research has been done so far:


    Your metabolism might be all wonky.

    This drops a lot during a crash, and there’s some data to suggest that this persists even after you go back to a normal diet, says Johannsen. That means you’d be eating more calories and still burning fewer, which would obviously lead to weight gain.


    Your insulin sensitivity (and risk of diabetes) might be impacted.

    The initial drop in weight might improve your insulin sensitivity temporarily, but researchers don’t know what effect repeated crash diets could have on it in the long run, says Johannsen.


    Fat might come back faster than muscle does.

    Remember how crash diets burn through your muscle tissue? Well, they might not bounce right back after the crash. “Your body’s first impetus is to rebuild the fat stores,” says Johannsen. So when you come off the crash diet, your body will want to store fat before it works on rebuilding your muscles. Because life isn’t fair.

    Bottom line: Crash diets might be a quick fix, but they can also be awful, dangerous, and come with lasting negative health effects.


    The whole basis of a crash diet is that it’s unsustainable, and that’s not what you should look for in any eating plan. Sure, you could lose weight quickly, and if you follow that up with healthier behaviors (like cutting back on sugar, eating less processed food, and working out more), the results might stick. (But honestly: How likely is that, actually?) That said, severely restricting your calories or eating only one food for any extended period of time can do some scary things to your body — and those effects might stick too.


    “Metabolically, we’re probably doing more harm than good,” says Johannsen. “Even if a little bit of weight is lost during that time, it could have a lot of immediate health effects as well as longer-term consequences.






    PLATE TECTONICS





    Tectonic plates are pieces of Earth's crust and uppermost mantle, together referred to as the lithosphere. The plates are around 100 km (62 mi) thick and consist of two principal types of material: oceanic crust (also called sima from silicon and magnesium) and continental crust (sial from silicon and aluminium).


    3 TYPES OF PLATE BOUNDARIES

    CONVERGENT PLATE BOUNDARY


    In plate tectonics, a convergent boundary, also known as a destructive plate boundary (because of subduction), is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide.

    DIVERGENT PLATE BOUNDARY
    In plate tectonics, a divergent boundary or divergentplate boundary (also known as a constructive boundaryor an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.

    TRANSFORM PLATE BOUNDARY

    A transform fault or transform boundary (also known as a conservative plate boundary, since these faults neither create nor destroy lithosphere), is a type of fault whose relative motion is predominantly horizontal, in either a sinistral (left lateral) or dextral (right lateral) direction.




    Advantages and Disadvatages of Technology








    In today's world, humans do things more convenient and have more access in the surroundings because of the advance technologies. Nevertheless, regardless of how far technology has taken humans and no matter how convenient it may make things, there are some disadvantages accompanying this level of access.






    Advantage: Great Discoveries In All Industries and Cost Efficiency

    Technology advances show people a more efficient way to do things, and these processes get results. In education, students are able to learn on a global scale without ever leaving their classrooms. In agricultural, thanks to advances in technology, which means cost-efficiency for farmers. In medical discoveries, credit to machines and computers that assist in the research process and allow for more intense educational research into medical matters. Cost efficiency is an advantage in some ways and a disadvantage in others. As technology advances on existing processes and platform new ways to accomplish tasks, machines are proficient to manufacture the same output than humans in assured industries. This results in cost savings for business owners, allowing them to invest in growth, which throws in on an affirmative level to the economy as a whole.


    Disadvantage: Dependency and Less Value In Human Workers


    The highly developed society becomes technologically, more people begin to depend on computers, cell phones and other forms of technology for everyday survival. This means that when a computer crashes or technology collapses, humans become almost immobilized until the trouble is resolved. This kind of dependency puts people at a discrete disadvantage, because they become less independent. On the other side, human workers hang on to less value, which is a disadvantage. Because machines automate processes and do the work of 10 people with one computer, companies find they don't need to employ as many people to get the job done.


    As technology become even more advanced and efficient, this will continue to be a growing disadvantage of technology and an issue that has a global impact.

    Hail the Hydra, an Animal That May Be Immortal


    Did you know that the water animal Hydra never gets old and can live forever.When a Pomona
    college biologist Daniel Martinez start to research and state that" I started my original experiment wanting to prove that hydra could not have escaped aging","My own data has proven me wrong- twice."

    Hydra are known for their regenerative capabilities. Most of their body cells are stem cells, Martinez said. These cells are capable of continuous division and differentiation into any cell type in the body. In humans, such "totipotent" cells are present only in the first few days of embryonic development. Hydra, by contrast, constantly renew their bodies with fresh cells.

    In 1998, Martinez and his colleagues published a study describing how they found no signs of aging in mature hydras over four years. To detect aging, researchers look at senescence, which is defined as an increased rate of death and a decline in fertility with greater age. In that 1998 study, researchers couldn't pin down whether or not hydra fertility declined with age.

    The new research involved creating little islands of paradise for 2,256 hydras. The researchers wanted to give the animals ideal conditions, which meant giving each an individual dish, with the water changed thrice weekly, plus meals of fresh brine shrimp.

    Over eight years, the researchers found no evidence of senescence in their coddled hydra. Death rates held constant at one per 167 hydras per year, no matter their age. (The "oldest" animals studied were clones of hydras that had been around for 41 years — though individuals were only studied for eight years, some were biologically older because they were genetic clones.) Likewise, fertility remained constant for 80 percent of the individual hydras over time. The other 20 percent fluctuated up and down, likely because of laboratory conditions.

    "I do believe that an individual hydra can live forever under the right circumstances," Martinez said.

    In the wild, disease, predators and water contamination kill off hydras before they can achieve immortality. But the findings fly in the face of old models that assumed that all animals must decline with age, Martinez said. And that means that studying hydra could help scientists unravel the mystery of why most animals do age.

    "I’m hoping this work helps sparks another scientist to take a deeper look at immortality," Martinez said, "perhaps in some other organism that helps bring more light to the mysteries of aging.”



    I chose this topic to post because I was amazed that this water animal hydra never gets old and can live forever. I learn that this water animal has the regenerative capabilities and hydra can reproduce themselves by making another small hydra. When hydras bud themselves, they're reproducing using mitosis. But hydras, like some single-celled eukaryotes, can also reproduce using meiosis. Ordinarily hydras are neither male nor female, but when they are going to reproduce this way, one hydra grows testes to make sperm cells and the other hydra grows ovaries to make egg cells. These sperm and egg cells can fuse to begin a new hydra. This has the advantage of giving the new baby hydra a different combination of DNA than either of its parents has, allowing hydras to evolve rapidly to respond to changes around them.
             Science Organism
    Believe it or not, there's a microbial zoo living inside you, literally trillions of microscopic organisms―more than 10,000 different kinds of them―all co-existing with each other and you.
    In fact they outnumber you ten to one and ninety percent of the genetic material, (DNA and RNA) in your body is not yours, it belongs to the bacteria that is located mostly in your gut, but some also live on your skin and even in your nose.
    Exactly what those different life forms do has been the subject of some exciting research in recent years, and while a few of these organisms can sometimes wreak havoc with your system, the majority of these little "bugs" are good, helping you digest your food, stay protected from infections, and even keeping your immune system properly regulated to fend off autoimmune diseases like asthma, allergies, and diabetes.
    The community of microbes living on and in your body is unique to you – like your fingerprints – and is now being regarded as a key contributor to your overall health.

    OCEAN BASIN

    Ocean Basin Formation

    Image result for ocean basin formation
    The Ocean Basins are formed from a series of processes beginning with a separation of two diverging plates where molten rock materials well up from the underlying mantle into the ridge or gap between the diverging plates,solidifying into an oceanic crust.In time, a new ocean floor is created.

     About 70% of the planet's surface is made up of ocean basins, which are the regions that are below sea level. These areas hold the majority of the planet's water. In fact, it will help you to recall this term if you remember that a 'basin' is a large bowl, much like your kitchen sink. So, an ocean basin can be thought of as a large bowl that holds ocean water. The floors of our world's oceans contain features that you might recognize as being similar to some structures on land.

     Harry Hammond Hess and Robert Sinclair Dietz Concluded from this evolution of ocean basins that the Atlantic and Arctic basins are expanding, as exhibited by the spreading of the Mid-Atlantic Ridge.At the same time, they also speculated that the Pacific basin is shrinking,  as exhibited by the southern movement of the East Pacific Rise (Northwestern Boundaryof the Pacific Plate). In effect, the ocean basins are ceaselessly "recycled"






      In this study of Ocean Basin i learned how our oceans are formed.From The Process of two Diverging plates createing gaps where hot molten rock, called magma and When the magma seeps through the gaps, it solidifies as it cools, creating a new layer of ocean crust.









    The Primordial Soup Theory

     

    The origin of life is a scientific problem which is not yet solved until these days. A lot of theories were presented to know where life really began. In general terms, it is suggested that all life today started by common descent from a single primitive life form. One of the most known theories of the origin of life is the Primordial Soup Theory.


    The idea came came from Russian scientist Alexander Oparin and English geneticist John Haldane. Oparin and Haldane thought that with the mix of gases in the atmosphere and the energy from lightning strikes, amino acids could spontaneously form in the oceans.



    The Primordial Soup Theory suggest that 3 billion years ago, life began in a ocean as a result of the combination of chemicals from the atmosphere and from the space and resulted into the formation of amino acids, the building blocks of proteins, which would then evolve into the first species on Earth., the bacteria, named Cyanobacteria.
