EVALUATION OF THE GENDER DIFFERENCES AND REPRODUCTIVE PHYSIOLOGY OF CATFISH (ANCISTRUS CIRRHOSUS)

Nilay Seyidoglu, Cetin Yagcilar

Show Abstract

Abstract:

Ancistrus cirrhosis is a catfish which used for removing algae from aquariums. It is known that it’s the largest genus in the Ancistrus family and is represented by 64 species. It feeds by herbal supplement and can tolerate a wide range of water condition. In general, all kinds of algae containing foods and also vegetables such as peas, carrots, spirulina are included in their diet.  
The male fishes are larger than female fishes. Although female fishes have tentacles in the upper of the head, this structure is not available in females. The inside of the slot is cleaned by male fishes for reproduction. The male fish that cleans the area attracts the female to the breeding zone with their behavior. The female fishes adhere the eggs to clusters with adhesive properties. After pouring the eggs, the male fish looks at the eggs for 7 to 10 days. During this period, the male does not leave the nest even if the fish is to be fed.  
In our study, it’s aimed to observe the sex differences and reproductive physiology of Ancistrus cirrhosis fishes. 7 male and 7 female fishes were studied and took their pictures and recorded the videos during the behavioral process. All this process were also staged graphically. As a result, these fishes are being important in aquarium sector with its gender differences and nutrition.

Show Abstract

Abstract:

Emollients are essential ingredients in all types of personal care products and cruial especially for skin care category. The basic building blocks of most emollients are long chain hydrocarbons, often combined with alcohols and acids in the form of esters. Esters have been increasingly used in cosmetic formulations over the past few years in a wide variety of applications for their sensorial and emollient properties. The majority of esters are either derived synthetically from petroleum or from natural triglycerides. The raw materials which are commonly used in FMCG like cyclomethicone, natural silicone, mineral oil, jojoba oil, lanolin oil, antimicrobial efficiany agent and preservative have their alternatives in the form of emollients which are special esters products. In this paper, common special emollients which have an ester form will be evaluated in terms of their end user sensory feelings as well as general informations about their production details.

Byoungho Jun

Show Abstract

Abstract:

The purpose of this study is to analyze the adoption of internet-only bank in Korea in terms of benefits (functional, social, experiential, economic benefits) and differentiated services (customization and service diversity). Data was collected using an online and offline survey of 117 internet-only bank users and analyzed the data using structural equation model (SEM). The results of empirical analysis using SmartPLS show that functional benefits, experiential benefits, and customization are significantly related to the user’s satisfaction, but economic benefits, social benefit, and service variety are not. This study has the significance in that it examines the user’s attitude toward internet-only bank in terms of benefits and differentiated services while other studies analyzed banking services focusing on the attributes of banking channel itself.

Merve YILDIRIM, Bahar KAFADAR, Aslı Merve ÇAKIR. Özlem ESEN

Show Abstract

Abstract:

The scented cosmetic products such as colognes are composed of basically ethanol, water and fragrance. The use of colognes is favorable because of the fragrance. However, the need of them has been increased to the global health issues and the purpose of using colognes has differed because of its alcohol content. Frequent use of colognes leads to irritation, dryness and redness on skin. Therefore, the addition of the humectants into the cologne formulations may help to decrease the skin problems. In the study, two humectants, glycerin and mono propylene glycol (MPG) were formulated in cologne. It was concluded that the skin moisture was increased by glycerin addition much better than MPG, but the microorganism count after mono propylene addition was lower than glycerin.

THE STRUCTURE OF VIRUSES AND VIRUS TYPES THAT AFFECT HUMANS

Ezgi SAYINKAPLAN

Show Abstract

Abstract:

From the Latin, the word virus means poison and "infectious disease agent", before Dmvitri Ivanovsky discovered viruses in 1892, was first recorded in 1728. The debate on whether viruses are alive or not is still running and since viruses are found wherever life exists, it is thought that viruses have been present ever since living cells first developed. Viruses can exist as virions and independent viral particles in the infected cell or in the process of infection. Virion, a single virus particle that contains all the structures of a virus, consists of two or three parts; a viral genome, which may be either DNA or RNA and large molecules carrying genetic material, a protein layer called capsid that surrounds and protects genetic material and a lipid envelope surrounding the protein layer. In this study, the sections that compose the structures of viruses were generally examined and types of viruses that derive from different sources, have different genetic structure and affect people were discussed.
