In this paper Taguchi method is applied for determining the effect of process parameters on vortex tube made of Delrin material. An Experimental work is carried out to analyze the performance of vortex tube with five controllable input parameters namely diameter of the orifices, diameter of the nozzles, length of hot tube, tube diameter and inlet pressure. Cold temperature is considered as output parameter. The various parameters like S/N analysis, ANOVA and Optimal Cold Temperature were carried out in order to determine the effects of process parameters and optimal factor settings.

Present study deal with the investigation on parametric study on self supporting chimney considering in three different cities of India . The 65 m height and 80 m height of chimneys were selected and analyzed for wind force and seismic loadings for seismic zone III , IV and V, as per Indian standards (IS: 6533 -1989 ) and IS 1893(part 1) 2002. The wind loads were determined as per IS 875-1987 for the basic wind speed 47m/s, 50m/s and 55m/s. The thicknesses of the chimney were kept constant for this study. Significant increments were observed in displacement, bending moment and shear force for different seismic and wind zones. The results of self supporting steel chimney were obtained out with the above said parameters.

Deinking is an important step in recycling of waste paper and flotation is commonly used in this process. Conventional laboratory-scale flotation cell was used to study ink removal from waste printed papers. Different type of surfactants such as, cationic, anionic or non-ionic, were employed in pulping and flotation processes. Two surfactants of each type were used in this comparative study. The effect of concentration and type of surfactant, consistency, pH and temperature on the deinking was investigated. The efficiency of deinking process was determined by measuring of the brightness of hand sheets formed of deinked fibers. The highest brightness was achieved by using 2-octanol alcohol (as a non-ionic surfactant) in pulping and flotation stages. Under optimum conditions for this surfactant, a brightness of 86% is obtained from a feed of 44%.

Verbs which drives from “bayestan” (must,should),”tavanestan”(can) and “shodan” are simple modal verbs in Persian. Syntactically, these verbs are defective. Semantically ,these verbs at least receives two readings :epistemic modality and root reading. whenever they conveys concepts like “permission”, ”necessity” or “will” they have root reading, which divides into two sub_ classes root_ deontic and root_ dynamic. epistemic modality conveys “possibility” or “”probability”. Epistemic_ objective is based on scientific data but epistemic_ subjective is based on personal judgments .Root modality co-occurs with subjective forms and epistemic modality co-occurs with indicative forms.

The present work is an attempt to identify key structural features that govern the anti-malarial activity of Pyrido[1,2-a]benzimidazoles using pharmacophoric analysis. The work is based on a dataset of fifty-six molecules comprising diverse derivatives of Pyrido[1,2-a]benzimidazole. The structures were drawn, optimized and aligned using standard protocol. The final model was developed using aligned molecules. The analysis reveals that the anti-malarial activity of Pyrido[1,2-a]benzimidazoles is related with features. The analysis points out that in future modifications these features should be retained.

A simple, highly sensitive, accurate and selective method for determination of trace amounts of Pb(II) in water samples is presented. a novel ethylenediamine-functionalized multi-walled carbon nanotubes(E-MWCNTs) solid-phase extraction adsorbent was synthesized by covalently O-(7-azabenzotriazol-1-yl)-N,N,N´,N´-tetramethyluronium hexafluorophosphate onto the surfaces of multi-walled carbon nanotubes (MWCNTs). The stability of a chemically ethylenediamine-functionalized multi-walled carbon nanotubes(E-MWCNTs) especially in concentrated hydrochloric acid was studied which used as a recycling and pre-concentration reagent for further uses of (E-MWCNTs). The method is based on (E-MWCNTs) of Pb(II) on surfactant coated C18, modified with a ethylenediamine-functionalized multi-walled carbon nanotubes(E- MWCNTs). The retained ions were then eluted with 4 ml of 4 M nitric acid and determined by flame atomic absorption spectrometry (FAAS) at 283.3 nm for Pb. The influence of flow rates of sample and eluent solutions, pH, breakthrough volume, effect of foreign ions on chelation and recovery were investigated. 1.5 g of surfactant coated C18 adsorbs 40 mg of the Schiff’s base which in turn can retain 15.2±0.8mg of each of the two ions. The limit of detection(3?) for Pb(II) was found to be 3.20 ng l -1. The enrichment factor for both ions is 100. The mentioned method was successfully applied on determination of lead in different water samples. The ions were also speciated by means of three columns system.

In criminal law, cybercrimes, are very broad scope, and includes a variety of theft, fraud, deception, harassment, intimidation, extortion viruses and cyber terrorism are. The Iranian criminal law, criminal called extortion does not exist, but in Article 669 of the Penal Code, adopted in 1996, the sanctions decreed that, whenever someone else, in any way threatening to kill or harm breath, or honor, or financial , or disclosure of the secret, to his or her relatives, to those determined by the demand of funds or property, or demand it, or omission done, or not, to flogging up to 74 lashes, or imprisonment of two months to two years he will be sentenced. Material element of the crime of extortion by putting the publication of private photos in a virtual environment, action is threatened. The threat that, in fact, a kind of spiritual abuse, and psychological pressure, the announcement and expressed my intention, and behavior that is illegitimate and illegal, did not intend to do it. In other words, threats, intimidation, and fear on the other side, by creating fear in order to obtain money, or is immoral gratification. Rea required for this crime, including general and specific intent is bad faith, malice general, the determination wisely and deliberately in committing the crime. In other words, the perpetrator knows and is aware that the leaking privacy, criminal act, and against the law, with knowledge, bad intentions, will commit this action. In this study, after the introduction of the concept of cyber crime, the different types of cyber crime, offer suitable solutions for the prevention of computer crime will be addressed.

This study looks at the students’ perceptions on the effectiveness of the invention project showcased at USIM Young Inventors Fair in promoting critical and creative thinking among the First Year Bachelor students of Universiti Sains Islam Malaysia (USIM). 350 students were involved in this quantitative study which aimed to assess the students’ perceptions on the effectiveness of using an invention project in promoting their thinking skills. An invention project was assigned whereby students were to reflect on the critical and creative thinking skills they have acquired while completing the project. Results revealed that the students perceived that the invention project has indeed contributed in promoting their critical and creative thinking skills. Most of them reported that they had benefited through their involvement in the invention project. All 18 assessed statements have mean scores below 2 and the standard deviations are less than 1. Thus, using the invention project is indeed an effective way to promote critical and creative thinking skills of the students.

Two different samples of fish were procured from Ombi River, Lafia – Jos Road, Nasarawa State, North-central Nigeria. Catfish (Claria gariepinus) and Tilapia fish (Oreochronis niloticus) and shared into two parts, smoked and unsmoked: The fish samples were analysed for protein, moisture, ash, lipid and carbohydrate content. The unsmoked and smoked Tilapia fish showed higher protein and carbohydrate content (31.50 % - 32.81 % and 13.00% - 16.27%) respectively compared to unsmoked and smoked cat fish (21.00% - 19.80% and 0.48% - 2.47%) respectively. While the unsmoked and smoked Tilapia fish showed low moisture, ash, and lipid content (12.00 % - 10.40 %; 15.60 %-16.00 % and 26.50 % - 25.83 %) compare to the unsmoked and smoked cat fish (21.00% - 19.80 %, 20.40% - 21.40 %, 28.33 % - 27.50%) respectively. High protein content in Tilapia fish proved the fact that Tilapia fish belongs to the category of fish with high protein. While high lipid content in Catfish, gave an indication of cat fish belonging to category of fish with higher lipid. The results of the analysis showed variation compared to the result of other similar researches. This could be as a result of some factors, which may include geographical location, sex, species, age, nutrient, migration and Season. The processing method altered the composition of the Cat and Tilapia fish as a result of heat where denaturisation of the fish composition is believed to have occurred. The low moisture content in smoked fish samples is as a result of water loss during smoking process and low ash content in the unsmoked fish samples can be ascribed to low content of inorganic elements. It can thus be concluded that fresh fish is more nutritious for human consumption.

Psychoanalytic theories of both modern and postmodern dimensions have given us infinitely rich, complex and subtle ways of thinking. It most cases it has crossed the boundaries of speaking about body and sexuality, identity and difference, and also knowledge, language, culture. These theories mostly see gender as fluid suggesting our gendered subjectivity as unstable as it is vulnerable to the subversion of unconscious desire. In particular, psychoanalysis not only suggests the variety of biological drives but also the complicated social construction which arise out of the experiences within our particular historically and culturally situated families. Psychoanalysis still remains central to contemporary work on gender despite imperfections, limitations and omissions even in the light of powerful later developments. It has opened up crucial insights about conceptualizing the construction of identity and their changes by the meanings of language and culture.
