Micro Needles Microneedles are tiny needles, typically measured in millionths of a meter, intended for delivering drugs. This method is entirely new, which involves superficial procedures of piercing the skin by moving systematic needles over the surface. Micro-needling has become famous over time due to its safety, simplicity, effectiveness, and its economical nature for the users and the dermatologists. Recently, the method is extensively utilized to administer vaccines and other therapeutic drugs. The idea of micro-needling in biochemistry was coined in 1995 when Orentreich, who termed micro-needling as a way of sub-cision for treatment through the scar and in 1997, independent micro-needling was done by a great surgeon named Camirand who applied inkless tattoo guns to drive off anxiety from surgical scars. The micro-needling concept has evolved since then to suit the administration of drugs by various surgeons. Surgeons have designed different instruments used to administer medicines. The commonly used is derma-roller that is 12 centimeters and 4 square centimeters drum-shaped cylinder on one side dotted with eight rows with round arrangements of 192 fine microneedles (Gill and Prausnitz, 2017).…

All You Need to Know About Solar Panels Solar power is one of the most common forms of green energy. Solar power is usually generated by solar panels that tap the energy of the sun. The benefits of solar energy range from affordability to being environmentally friendly. If you are interested in using solar power, you must understand how it is generated. Here is a brief guide on how solar panels work. Converting Sunlight into Electricity A solar panel consists of layers of silicon cells, a glass casing, a metal frame, and wiring to allow current to move from the cells to electrical appliances. Silicon has conductive properties to enable it absorb sunlight and convert it into electricity. When sunlight reacts with a silicon cell, the electrons are excited and this triggers a flow of electricity. This is called the photovoltaic effect. The PV phenomenon was first discovered by Edmond Becquerel in 1839 and describes how semiconductors generate electricity when they come in contact with sunlight. When sunlight hits solar panels, the PV cells produce a direct current. Direct current…

Meat Grilling Safety The largest populations of in the world tend to have a high affinity for grilled meat because of its appealing taste. However, Incautious practice of grilling meat is associated with high levels of Polycyclic Aromatic Hydrocarbons. Polycyclic Aromatic Hydrocarbons refers to the kinds of chemicals that are formed when muscle meat is cooked or exposed to direct and high temperatures which include grilling the meat over direct flames (Lee, 2016). Thesis: Reduction of smoke during cooking of meat is a crucial practice to lower the levels of associated Polycyclic Aromatic Hydrocarbons. There is a large portion of the human population who are in love with grilled meat. It is, therefore, of a concern to address the issue of the Polycyclic Aromatic Hydrocarbons in meat because thousands of people consume grilled meat daily. The frequent and prolonged consumption of grilled meat means that more and more people are exposed toPolycyclic Aromatic Hydrocarbons daily. In that context, the exposure to the chemical could significantly compromise the health of the consumers. That is an adequate justification for this paper. The…

A BRAIN TUMOR IMAGE SEGMENTATION TECHNIQUE IN IMAGE PROCESSING USING ICA – LDA ALGORITHM WITH ARHE MODEL   4.1 OBJECTIVE             In digital image processing, image segmentation is the principal methodology that is to be used frequently.  In digital image processing, noise reduction and enhancement techniques played a vital role.  The brain is the significant and significant organ of the human body, which is to be controlled by the nervous system.  The brain tumor will occur when some brain cells presented in an unusual case.  The brain tumor detection is the crucial task for the analysis of diagnosis and the curing the tumor.  The brain tumor will identified in the correct manner, which can give a fast and effective way of determination of the tumor.  In this chapter, we proposed a brain tumor image enhancement technique with the help of the ICA – LDA (independent component analysis – linear Discriminant analysis) algorithm with ARHE (adaptive region-based histogram enhancement) model.  The image fusion technique is to apply for a combination of the two or more input images.  In this chapter, the…

Why Many Lab Apparatuses Are Made of Glass   Laboratory glass is multiple types of equipment made of glass and which are used in various equipment. Most commonly, glassware is in chemistry procedures. Many of the laboratory’s glassware have unique functions, and thus, they are manufactured using unique types of glass depending on their usage.   Glass has many benefits, and that is the reason it has been so popular among scientists for many years. The leading advantage of the glass is its inert nature, and thus it does not react with many chemicals. It is also cost effective as compared to other materials since it can be reused for an endless number of times. Plastic an alternative of glass in the lab has many drawbacks since it will quickly react with different chemicals.     Glass can easily break when mishandles. Most of the lab technicians undergo training on how to efficiently the apparatus. Also, they are taught the hazard of glass and how to deal with injuries that result from the breakages. To ensure that the equipment lasts…

What is color blind racism? It can be asserted that racial issues are among the most uncomfortable topics to discuss in the united states. Various ideas to address this sore spot have been brought forward by the united states psyches. Currently, the common approach is termed as racial colorblindness. Racial colorblindness is the assumption that racism is no longer a problem nor does not exist and that all individuals are treated as equal as possible, without concern for ethnicity, race or culture. People who practice colorblind racism claim that “they do not see the color of people’s skin and believe everyone to be equal”. According to…. colorblindness is meant to eradicate discrimination and promote racial equality in society. What is an example of color blind racism? According to… color blind racism came into existence after the civil rights era as a way to absorb immigrants in the early 1900s. Since then, individuals in society have embraced it in the belief that it would aid in ending discrimination. A current example of color blind racism can be seen in schools where…

How to Choose an Electric Mountain Bike It took little time as expected for the promise of electric motorbikes to take over the automotive industry. The development of the electric motorcycle in the past decade has been because of the significant technological advancements. An electric mountain bike is a bike that has electric assistance. Electric motor bicycles make use of the mid-drive, or center-drive, motors coupled to a power pack. Motor Brands to Consider While Choosing an Electric Mountain Bike Bosch Bosch offers the broadest range of mid-drive motors with five useful variants. Bosch Performance CX motor is the best motor brand, and it provides 75Nm of torque over a sustained power curve.

Brose Brose is a German mid-drive motor maker and happens to be the quietest mid-drive motor in the market. It is a belt-driven system, which contributes to…

Global Carbon Cycle Organic compounds contain the carbon element and are present in living things. Carbon always moves within the earth’s atmosphere, biosphere, hydrosphere and lithosphere. In rocks, carbon moves as calcium carbonate, in living organisms as carbohydrates or sugars and the atmosphere as carbon dioxide (CO2). The carbon cycle among earth spheres starts with green plants which absorb the CO2 from the atmosphere through photosynthesis producing carbon-containing sugars. From the plants, animals eat the plants obtaining sugars from chlorophyll trapped during photosynthesis. CO2 is released to the atmosphere when the animals break down the carbohydrates through respiration and when they decay. Fossil fuels- oil, coal and natural gas are produced when dead animals and plants decay under high temperatures and high pressure. These fossil fuels are in turn used by human beings for heating, operating machinery and other purposes. When people burn these fossil fuels to produce energy, carbon dioxide levels in the atmosphere also increases, and the cycle begins. Deforestation and slash burning of forests The carbon stocks remaining in forests around the world are currently at risk…
