Moving in line with technology

The presence of a technology is often accompanied by the emergence of news things too, whether to complement or provide another choice to consumers. Just look at when Microsoft launched its Windows 7 operating system, which was then followed by the launch of a number of devices supporting the latest hardware in the form of a keyboard, mouse, and web cam. Windows 7 promises a more pleasant experience in multi-user, such as a more innovative touch screen to navigate the system. 

The device offered by Microsoft in its latest breakthrough is the Wireless Comfort Desktop 5000, Bluetooth Mobile Keyboard, Life Cam Cinema, and the Wireless Mobile Mouse 4000. Overall it was an innovative product that is supported by Windows 7. Wireless Comfort Desktop 5000 is a keyboard and mouse combo that has a Task bar button, a new feature that allows users to navigate quickly through several windows in windows 7. 

Bluetooth Mobile Keyboard 6000 is the thinnest keyboard owned by Microsoft. This new keyboard has a unique form of ergonomic design. Life Cam Cinema became the first web cam equipped with 720p high-definition quality and low light performance of the slick. While the Wireless Mobile Mouse 4000 is a mouse that is equipped with technology that has been manufactured like Blue track and sold at affordable prices.

Repaint your Wall in House


Usually in Indonesia people, in Ramadhan, people prepare them house to face Idul Fitri day. One of habits that Indonesia people do is repaint wall on their house and make the house beautiful.

  • Before you repaint your wall, you have to know the condition your wall on your house. The conditions are good or not good. It will influent your paint, because the paint it depends on the situation. Wall with condition if there is not has mushroom, lime kiln limepot.
  • On good condition, the wall surface only being cleaned from dust or oil. If you do not clean the dust, your wall will have a black flack.
  • The next step is paint a sealer (basic paint) which became a connection between the old paint and the new paint. On this sealer, the new paint it will be easy to stick with the old paint. After the sealer paint on the wall, wait for 3 hours until the paint dry.
  • And then, the new paint is coming. Give 3 or 4 times paint to get good result and give a few hours, maybe 3-4 hours and give another paint.

The concept of evolution in biology

In 1858 a biologist named Charles Darwin (1809-1882) gave a lecture sponsored by the Linnean Society in London, and a year later was published his book The Origin of Species in 1859. Establishment posed in lecture and the book is that all forms and types of creatures that live there now exist in the world, with affected by various natural processes, evolve or grow very slowly from the forms is very simple, one-celled creature into several new, more complex types. New types of creatures, each also evolved into new species into an increasingly complex, so that takes a very long time. But who knows in the 1700s the development of biological sciences in Europe and America in fact dominated by science theory of natural theology. This is precisely contrary to the concept of the theory proposed by Charles Darwin. Broadly speaking, scientific theories of natural theology is a philosophy which aims to discover God's plan by studying nature, so do the classification of species of natural theology to express the level of the scale of life created by god.

Carolus Linnaeus (1707-1778) that we know as the father of taxonomy. Linnaeus developed the binomial system (the system of classification of living things) that are still used today for the naming of organism on the basis of genus and species. Linnaeus also adopted a system for classifying similar species into a particular category of tiered levels. So that for Linnaeus, grouping similar species together showed no evolution of a relationship. Back to the concept of Darwinian evolution, the laity in western Europe initially very opposed to this establishment, and although already there are numerous papers on the historical process of evolution of human society at the time , but the idea of evolution of living species can not be accepted. That's because in the mid-19th century in Europe there is a generation and re-tightening of religious life, and ideas like the idea that Darwin considered the ideas that conflict with the infidel religious belief which says that all kinds of creatures in the world (including human ), is the result of God's creation are absolute. Except that the idea that humans and apes are descended from a creature the same, even that man is a monkey, an idea that is too difficult for lay people to accept.

In addition there is also Charles Darwin's other biologists, namely A. Wallace (1823-1913), independently of Darwin had developed the idea of evolution beings in the same world, although more expanded Wallace about the process of natural selection in determining the physical form of a new species in the evolutionary process. Darwinian natural selection, only mention about it in passing and in his lecture. Basically there is no difference between theory concerning the processes of biological evolution from these two experts and both are of the opinion that among the individuals within one species there is always a small difference. Some individuals are vulnerable less able to withstand the pressures of nature, and off, whereas individuals who are stronger can survive and live straight, gave birth to offspring and pass on their properties had been strong for some of his descendants. In the next generation of this process over and over again, and so on. According to Wallace, the more cruel and harsh natural pressure, the higher the quality is a requirement for an individual organism within a species at a certain generation, and if the natural state of change, then only individuals of a species that has the properties can survive to live. And this is by Darwin and Wallace have called "natural selection".

How to Overcome Natural Acne

Natural remedies just as effective as medication in dealing with acne. In fact, the possibility of better and more powerful. Sometimes, it takes the body is balanced nutritional care and proper body. Healthy with natural ways are the steps very well for the achievement of useful life. Similarly, in conducting special body treatments, among others concerning the proper skin care and especially about acne. Here, the natural treatment recommended

Use of honey

Of course everyone has to know this food, in addition to good for the health of honey is also beneficial for our skin care, especially regarding facial treatments. According to research, honey contains antibacterial compounds so good for disinfecting and healing minor acne on the face. In addition, gentle for sensitive skin. Apply honey to the face (such as wearing a face mask) with regularly. Do it regularly, with one or two times a week
Cleaning Face on a regular basis

Perform facials to cleanse the face with acne soap as much as two times a day. Wash the face with a sulfur based soap formulated for acne. First when we wake up and try to do as well as gently as possible and before bed. Cleaning the skin is excessive force sebaceous glands to produce more sebum which has the potential to improve acne in face


Drink Multivitamins

Acne on the face may member sign that there was something wrong in the skin because we know the skin is also dependent on the nutrients that we consume. Skin is also an important organ that is often overlooked. If you do not receive proper nutrition, your body will fight back. One way is to insurgency skin with excessive sebum produced so clog the pores on facial skin and reduces the skin's ability to resist against bacteria that exist and this may have potential in acne

Eating Carrots

Carrots contain beta carotene fibers are also included in vitamin A. Vitamin A strengthens the protective tissue and skin to prevent acne and help reduce sebum in the skin. Vitamin A is also important to maintain and repair the skin and tissue that build the mucous membrane. Vitamin A is also a powerful antioxidant that is required to remove body toxins

Avoid Makeup

Pressed in the skin of makeup products can cause the pores on the face of congestion, create more pimples and blackhead. If you must wear makeup, use cosmetics, which is basically water, not with oil-based materials

Consumption of Zinc

Zinc is antibacterial compounds and essential elements in the glands that produce oil for the skin. Low dietary zinc can cause acne on the face

Keep hair off our face

If you cut bangs hair long, then lift your bangs to stay away from your face. Hair also contains oil and when exposed to direct contact with the skin of the face, it was likely that the oils from the hair will stick to the skin so that the potential of acne on the face

Implementation of a good experiment


In accordance with some experiments that we often do both at the school and even at university level, we can set up several questions that should be considered in conducting an experiment. Practicum course at the university in the state of the system which does not always allow us to focus on the experiment.

Therefore, to conduct a good experiment needs to be seen a number of factors, among others

  1. Repeating the experiment in the same circumstances
    With this road soon becomes obvious errors that arise due to miscalculation in the experiment and other oversight. Also with the repetition several times can be reduced due to effects such a random error in reaction time, for example in the use of a stopwatch
  2. Repeat using other measuring devices
    If a meter is damaged or suspected of the situation is less precise, clear way to handle it is to replace these tools with other tools. In normal practice, if the experiment goes well, students do not have to think about this problem. But lab officials should check all equipment regularly
  3. Doing a comparison with the equipment under other circumstances. If there is suspicion that a formula or theory is incompatible with the existing experimental results, may place the necessary changes
  4. Comply with practical instructions in the use of tools
    Ie, before a device is used, its use should be studied first go through this guide so that the usage will be more effective and the existing experimental equipment can be prevented from the defects that we want and besides that can prevent us from dangers that might occur due to errors in using experimental tool

Anatomical Sciences and Problems of human multicolored


Anatomical sciences in the period between the 16Th century and the 19Th is a science that is certainly involved in the problem or mono genesis poly genesis human beings, and therefore also put big attention to ethnographic material and ethnographic at that time. Actually, since the time classical Greek philosophers such as Herodotus (circa 450 BC). Hippocrates (circa 400 BC), but especially Aristotle (circa 350 BC), who have all had to pay attention also to the science of human anatomy, have often used the skulls from neighboring nations who comes from the Greek-race other races, as comparative material in the study of anatomy.

Comparative studies of anatomy has become more intense, especially after the Europeans see more multi-colors of human physical traits, and after more and more appear essay containing ethnographic material as well as reports on the physical characteristics of different-colored people after the 16th century. An example of a similar study of comparative anatomy is such research conducted by physician Andreas Vesalius (1514-1564) of Spain and by physician and concurrent biologist and physiologist Carlos Linnaeus (1707-1778) of Sweden, as well as by a biologist and physiologist George de Buffon (1707-1788) from France.

The analysis and classification of multi-color features of the human body is widely based on information materials contained in the articles of ethnography, was carried out by JF Blumenbach, physiology and anatomy expert (1752-1842). In his book De Humani Generi Verietate (1779), which has the meaning of "Know the Origin of Human beings Aneka-Color" can be said was born of a science of physical anthropology as a new science. When it arises also concepts such as races Caucasian, Mongolian, Ethiopian, American and Malays, which is mainly based on skull characteristics, and about starting the beginning of the 19th century that most of the major universities in Europe present lectures in the science of physical anthropology. In the mid-19th century appear the names of characters such as PP Broca physical anthropology from France, R. Virchow from Germany, G. Sergi from Italy, which has members contribute greatly to the further development of the science of physical anthropology.

Classification of multi-color features of the human body in relation to the history persebarannya on earth, performed by a doctor named JC Prichard who lived from 1786 until 1848. He linking ethnographic data about the physical characteristics of the Tada ethnography of various peoples culture spread in the world. A theory which states that changes in the way of life, it means a change of culture, is also one cause of changes in human physical traits, developed and diuraikannya in two important works, namely Researches into the Physical History of Man, published in 1813 and The Natural History of Man in 1848. Both works are generally regarded as the beginning of the science of physical anthropology, taught at universities in Europe as a science in itself, separated from the science of anatomy.



Role of Graphs in the practicum


Graphs are often used in scientific literature because it can directly show the relationship between two quantities, and more important information more easily captured visually from the graph and the data listed in table form. Besides the role as the above graph, the graph also has a role in analyzing data and testing the model at the time of execution of the experiment.

The graphics are most often used is a Cartesian graph, which has an axis perpendicular to the cross, and fixed or linear scales on each axis. The simplest is a coordinate system in which both axes using the same scale and this is often used by people to draw a mathematical formulas. However, in most applications experimentally, the two quantities are about to be drawn in graphical form different from each other and the scale also have different things. A pair of data, such as Xo and Yo, respectively, can be placed on the graph area in accordance with the scale for x and y axis respectively.

In addition to Cartesian graph, some form of graphs that are commonly used in certain situations are polar graphs, and charts logarithmic graph consisting of log-linear (semi log) and log-log graph. In all types of graphs mentioned above, every point in the graph represents a particular data set, and vice verse. The histogram is a kind of graph that is often used in statistical analysis. Histogram showing the number of members or events that fall between certain values in the observable quantities. Need we know that basically the graph shows the relationship between two quantities, but the effects of other values which can be shown by putting a few curves, namely the value of the third scale different. But this way there is no scale for the magnitude of the third. Another way is to use three-dimensional graph that resembles the map arise, but the paint is very difficult and usually done with a special graphics program on the computer.
