A study on electro less plated yarn charactertics through Box Behnken Design by various the sliver nitrate amount, temperature and time has been reported. The cotton and polyester yarns were plated with sliver nitrate by electroless plating at various concentration, temperature and time. The surface morphology, antimicrobial activity, electrical conductivity, strength and elongation have been measured for cotton and polyester silver plated yarn. It is observed from SEM image that deposition and firm attachment of sliver particle over the surface of yarn structure. It is also observed that the sliver plated yarns have better antimicrobial activity, electrical conductivity and strength than normal yarn.

Corrosion is the primary means by which metals deteriorate. Most metals corrode in contact with water and also moisture in the air, acids, bases, salts, aggressive metal polishes and other corrosive solids and liquid chemicals. A suitable, effective and economical method has to be adopted depending upon the metal and its environment. Mild steel is of high industrial value. Metals, when subjected to surface treatment such as painting, enameling etc. should have clean surface, free from rust or oxide scales. For removing these rusts and scales, metals are immersed in acid solutions known as acid pickling bath. Generally hydrochloric acid is used in pickling bath. However, now- a- days sulphuric acid has replaced hydrochloric acid as pickling solution due to its economic advantage.

The main aim of present study is to examine the impact of environmental uncertainty (market ) , the investments and the quality of information available to the authority of the investments of accepted Tehran Stock Exchange listed companies , as well as the increasing introduction of a new theory named the actual authority .The investment authority in asset capital also like authority is on financial assets with the difference that these authorities appear on the real assets such as the land , building , machinery and other physical assets. By using the traditional methods of assessing projects such as the method of cash flow reduction (net present value and internal rate of return). With regard to the elements of environmental uncertainty, managerial authority and flexibility in projects and investments lead unrealistic assessment. So with regard to these drawbacks to use theory of investment authority and its effects in the value of the company and determining its value could be a great help to the better and more real assessment of projects and investments. So in case this question arises that with regard to this point that managers have such authority, how they regard the structure and the logic of investments authority in the analysis and designing their projects with a view to environmental uncertainty, the cost of investment, riskless interest rate and the quality of the information available for the company ?. For this purpose by using public formula of Cochrane a sample including 163 financial directors of the corporate (manufacturing) of Tehran Stock Exchange reviewed their views and opinions about the investments authorities. And also to analyze the data the linear regression was used. By regarding the conducted surveys it become clear that based on the above - mentioned managers points of view the independent variables ( environmental uncertainty , riskless interest rate, cost of investment and the quality of the information available ) have a significant impact on investment authority .

In this study, we sought to know what led to the creation of links between industry and academia in the Knowledge Based Economy for this purpose, a questionnaire was prepared to read relevant literature and the industry elite, elite university After collecting the necessary data parameters were identified

It is necessary to know the language and concepts of terms, because every science has the specific feature and Hafiz can be also considered in this way, therefore it is necessary to consider the titles and concepts such as faith and disbelief in his gazelles, because the concept of belief and disbelief refer to religion, hence it is necessary, they are considered in the field of knowing Hafiz, and this essay tries to search the meanings of belief, disbelief and love in his gazelles. I tried to concern the religious principles, my theism due to religion. There has been found a new approach in Hafiz’s poems other than the common a theism, as matter of fact, it is mystical atheism, in order to reach the love way which is higher than faith.

Just back from first frenzied shopping experience in the UK, a four year old ever-inquisitive daughter asked to her father, “Why do we not have a Harrods in Delhi? Shopping there is so much fun!” Simple question for a four-year-old, but not So simple for her father to explain As per the current regulatory regime, retail trading (except under single-brand product retailing — FDI up to 51 per cent, under the Government route) is prohibited in India. Simply put, for a company to be able to get foreign funding, products sold by it to the general public should only be of a ‘single-brand’; this condition being in addition to a few other conditions to be adhered to. That explains why we do not have a Harrods in Delhi.

Mobile Ad-hoc Networks (MANET) is the self organizing collection of mobile nodes. The Optimized Link State Routing (OLSR) protocol was designed to improve scalability of Mobile Ad-Hoc Networks (MANETs). OLSR protocol implements Multipoint Relay (MPR) nodes as a flooding mechanism for distributing control information. Nevertheless, OLSR was designed without security measures. There-fore, a misbehaving node can affect the topology map acquisition process by interrupting the flooding of control information or disturbing the MPR selection process.

Gulf heavy crude oil samples were separated into four fractions of saturates, mono-, di- and polyaromatics by elution open column chromatography. Alumina and a mixture of equal amount of silica and alumina stationary phases were separately used to study the effect of these stationary phases on the separation. The Gas Chromatography – Mass Spectrometry (GC – MS) results of the fractions show that the nature of the stationary phase may affect the elution of both aromatic and the saturate components of the oil. The pristane/phytane ratio ranging from 0.63-2.00 obtained for the crude oil fractions using the two stationary phases indicates an oxygen depositional environment for the source rocks.

A new semi-organic crystal of L-Alanine oxalate monohydrate has been grown from saturated solution by slow evaporation technique at room temperature. The grown crystal was confirmed by X-ray diffraction. The vibrational frequencies of various functional groups in the crystals have been derived from FTIR analysis. A wide transparency window useful for optoelectronic applications is indicated by the UV studies. The thermal behavior of the crystals has been investigated by TG/DTA analyses. The mechanical strength of the grown crystals was estimated by using Vicker’s microhardness tester. Second Harmonic Generation (SHG) efficiency of the powdered material of L-Alanine oxalate monohydrate (LAOM) tested by using Kurtz method.

Perceiving an environment is the first step linking people to a place. The emergence of this perception which is achieved through a mental and sensory process depends on several factors. In this study, different theories regarding the perception of the environment are investigated as the research objectives. The aim of this study is to measure the individuals’ perception paradigm of traditional housing style in Iran compared to modern housing style. Thus, it compares the perception of citizens of the two housing styles. The traditional style consists of a group of traditional houses from Zand and Qajar era in Shiraz while the modern style consists of modern houses in the same city. Accordingly, after a review of literature, the theoretical framework of the research was developed and a questionnaire and interviews were prepared during a month period. Finally, the quantitative data was analyzed with the help of SPSS Software and the qualitative data was analyzed based on the interviews. The results showed that there is a significant difference among different dimensions of home perception, including cognitive, emotional, interpretive and evaluative perception in both traditional and modern Iranian houses. In this relation, essential items such as stimulating the sense of smell in the yard, injecting the smell of humidity and soil, making physical and emotional bonds with residents show the conceptual differences between the traditional and modern houses in Iran.
