The parameters used to determine the most suitable cryoprotectant were the preservation of nanoparticle size and surface charge‚ along with their morphology. From the method optimisation study‚ it was found that increasing the cryoprotectant: nanoparticle volume ratio to 1:1 without using the centrifugation process‚ proved to result in the simplest method of reconstitution‚ requiring only manual shaking

What is evolutionary psychology? In the three and a half centuries since William Harvey proved that the purpose of the heart is to pump blood‚ physiologists have revealed the functional organization of the body in blinding detail. Their discoveries demonstrate beyond question that the structure of the body serves survival and reproduction. Further‚ there is near unanimity among biologists that this functional structure is a product of natural selection. In our century‚ psychologists have developed

Agar and Media Preparation— Agar plates containing King’s B Agar were often used throughout the experiment to support growth of Pseduomonas fluorescens. A recipe was used that included a mixture of 10g Proteose Peptone #3‚ 1.5g Potassium Phosphate Dibasic (K2HPO4)‚ 30ml 50% Glycerol‚ ~965ml water and 20g agar. The mixture‚ post- autoclave‚ was left to cool and 5ml 1M Magnesium Sulfate (MgSO4) was added and created about 40 plates. King’s B Medium was made using the same procedure as the King’s B

That was fast: The influence of light intensity on the growth and development of Wisconsin Fast Plants Introduction It is common knowledge that plants need light to grow and develop. This is done by the conversion of light energy into usable sugars during photosynthesis. Light absorbing molecules‚ known as pigments‚ absorb only specific wavelengths of visible light‚ mostly blue and red wavelengths (1). Whatever wavelength isn’t absorbed is reflected and the reflection is the color of plant we

us to identify and study them. Examples of social facts: institutions‚ statuses‚ roles‚ laws‚ beliefs‚ population distribution‚ urbanization‚ etc. Social facts include social institutions‚ social activities and the substratum of society or social morphology. Social facts are ways of acting and thinking - they comprise institutions‚ beliefs‚ practices‚ which eventually cristallize and limit the possible forms of individuals’ actions and forms of consicousness. Social facts also include social currents

Talon Cusp is mostly found in permanent maxillary lateral incisor but rarely found in primary teeth . ( Talon Cusp : is a very enlarged cingulum and sometimes looks like a separated cusp ) . - The Peg shaped lateral incisor : instead of having a normal incisal edge .. the

figure 2 at a 10.000 magnification. From the image‚ cellulose and banana kepok peel powder showed different size and shape. The banana kepok peel powder has been found many small particles in the surface that cause the morphology is irregular shapes and heterogeneous‚ whereas the morphology of cellulose is homogeneous with the structure of dense and large particles. Composition elements of banana kepok peel powder and cellulose from kepok banana peel analyzed using EDS are show in Table 1. The results

Blood Smear Test – Haematology 21/11/12 Aim The aim of this experiment is to identify the morphological features of Erythrocytes‚ leukocytes and Thrombocytes‚ to carry out out a differential white cell count and to describe the parameters used to identify different types of anaemias. Introduction Blood is a specialised body fluid‚ which acts as a liquid connective tissue‚ by being involved around the heart and the blood vessels within the body. The main components of the blood is 55%

Systematic Identification of Bacillus subtilis and Serratia marcescens Through a Battery of Tests and Plates Introduction: The purpose of this experiment was to use a systematic battery of tube tests and plates designed to lead to identification of two unknown bacterial species‚ from the combination of all results. A sample of bacteria was used‚ labeled “Sample 4”‚ from which both species was to be obtained‚ one gram positive and one gram negative. Table 1 is a list of the possible bacteria to

Late Modern English‚ a global language spoken around the world by over 2 billion people can trace its roots to the Germanic language introduced by Anglo-Saxon invaders in the 5th century. Before the arrival of the Anglo Saxons‚ many parts of Britain were bilingual Celtic-Latin speakers‚ although very few traces of Celtic remain in the English language – other than in place names‚ for example Avon and Ouse – which derive from the Celtic word for ‘water’‚ and words found more in local dialects than
