Orchis simia is a white-grey and pink colored orchid. Its labellum is shaped like a monkey; complete with four limbs and a tail. It inhabits limestone terrain, grassy and woodland areas. It is spread throughout central to southern Europe, the Mediterranean and North Africa. One third of all orchid species are deceptive, O. simia is no exception; it is nectarless and relies on food deception to attract pollinators. One of O. simia’s known pollinators is the Cidnopus pilosus beetle (Schatz 2006).…

polarity, vapor pressure, solubility and so on of different substances to be observed. 1 In our endeavor, we will be using specific types of chromatography, termed Thin-Layer Chromatography (TLC) and column chromatography. Essentially, TLC is an adsorption aspect of chromatography that uses a polar stationary phase and a non-polar mobile phase, and utilizes capillary…

Benefits of drinking water A. Drinking water is a essential to your health 1. By eating foods and drinking water can replace the amount of water that is lost each day in urine. 2. Water have several healthy benefits that improves moods, digestion, adsorption, circulation, creation of salvia, transportation of salvia, and transportation of nutrients, maintain the proper body temperature. Relieves fatigue, migraines, helps with headaches, helps in digestion and constipation, aid of weight loss,…

suitable carrier for drug delivery vehicles, since they are non-toxic,biodegradable, and non-antigenic[6, 21-23]. Due to their defined primary and high content of charged amino acids (i.e. Lysine) the albumin based NPs could allow electrostatic adsorption of positively or negatively charged molecules without the requirements of other compound…

resulted in the scientists discovering that the blender had separated the DNA and the protein, an examination showed that only the DNA had entered the bacteria when infection was occurring. This experiment concluded that the protein played a role in adsorption to the bacteria helped inject the viral DNA into the bacteria cell. Chase and Hershey’s experiments became an example of what Hershey’s friend’s and colleagues called “Hershey Heaven”. Martha Chase as stated before was born in Cleveland,…

Introduction Thin-layer chromatography, otherwise referred to as TLC, is a fast and inexpensive way to determine the amount of components in a solution or to identify an unknown compound. The principal behind TLC is when different compounds are placed on silica gel or alumina, (stationary phases) they will travel different distances when eluted with the proper solvent. According to ChemistryGuide, this is because the more polar compound has a stronger interaction with the silica gel due to its…

Different technologies are available for the treatment of gaseous streams containing VOCs (Volatile Organic Compounds), namely catalytic or homogeneous combustion, absorption, adsorption, etc. The goal is either to recover the VOCs, or to destroy them, thus avoiding, in both cases, their emission into the atmosphere. The treatment of “lean” streams, where the concentration of the VOCs is particularly low (e.g. lower than 1% v/v), is a particularly challenging case study as the low concentration…

The North Atlantic Ocean is a cold, inhospitable, and often ice-covered place. In spite of these harsh conditions, life continues to thrive in the cold, dark depths. The vast majority of these winter-resident species owe their success to various forms of anti-freeze proteins. Within Northern Atlantic resident species, there are six classes of Anti-Freeze Proteins (AFPs), generally categorized by molecular size, structure and effectiveness. AFPs are a remarkable exhibition of convergent evolution…

(1/m). Since fouling is going to take place in the separation process, the permeation flux will always be lower than the flux given by Eq. 4. Cake resistance -formed by cake layer- and fouling resistance -formed due to pore blockage and particle adsorption onto the fibers- are the other main contributors to the total fouling. So, when all of effecting parameters are taken into account, the total nonwoven membrane resistance can be calculated as follows:…

groups. The detection techniques mostly based on amperometric methods exploiting the electrocatalytic difference between the material of NP and ultramicroelectrode (UME) or potentiometric method measuring open circuit potential change upon the NP adsorption. The amperometric methods can be classified mainly into three classes such as electrocatalytic amplification, direct particle electrolysis, and UME…
