Fire Disaster Risk Plans on Preparedness: a Case Study of Informal Settlements in Nairobi County
Disaster preparedness is one of the phases within the disaster management cycle which covers implementation or operation, early warning systems and capacity building so that the population can react appropriately when an early warning is issued. Disasters have inflicted a heavy cost on human, material and physical resources. A comprehensive review of the literature has revealed that the development of disaster management strategies, such as preparedness, must be undertaken before the event strikes. The specific objective was to evaluate fire disaster risk plans for preparedness in Nairobi County. The research employed a descriptive research design to carry out the study in order to establish the relationships between the variables of interest. Exploratory and Evaluative research designs were used. Both quantitative and qualitative research designs were used to conduct the research. Households were sampled purposively such that only those from the informal settlement were interviewed and the research involved face to face interviews with 110 households by the use of questionnaires. Findings revealed that most respondents (89.6%) indicated that fire disaster risk plan for preparedness and awareness campaigns were important. Most respondents agreed with awareness initiatives both at household and institutional level except for allowing children to play near fire and lighting of cigarettes in fuel flammable areas. Fire escape plans were the most adopted fire awareness initiative as a fire disaster risk reduction measure.

Flagship programm and gender issues: a case study from Uttrakhand hill
This study conducted to analyse the gender biasness in education and employment sectors, which was carried out in rural area of Uttrakhand during 2000 -2010. The survey revealed that a direct intervention of some Flagship programs including women welfare meets some success in school education and provided sluggish rate of employments outreach. Further the maximum women engaged in agriculture and homestead work and a little percent of women engaged in government sectors. While Flagship satisfies the BPL and marginal groups, but there is further scope to enhance women motivation of women for their development. There is a need to make it more cost effective and pass on the benefits to workers. As for the last benchmark, the program ensures minimum leakages to a great extent by virtue of being self-targeting and non-discretionary.

Formulation and Evaluation of Controlled Release Floating Matrix Tablets of Lamivudine
The present study outlines a systematic approach for the development of Lamivudine floating matrix tablets to enhance bioavailability and therapeutic efficacy of the drug. Floating matrix tablets of Lamivudine are designed to prolong the gastric residence time after oral administration. These tablets have shown controlled release and there by proper duration of action at a particular site is achieved. The matrix tablets were prepared by using direct compression technique, by using polymers such as HPMCK15M, carbopol, gum karaya and other standard excipients. Sodium bicarbonate and citric acid were incorporated as gas generating agents. The effect of different concentrations of polymers on drug release profile and floating properties were investigated. LF16 prepared by HPMCK15M and gum karaya with effervescent agent was found to be more effective amongst all formulations. FTIR, DSC and SEM analysis were carried out to study drug excipients interactions and surface characteristics which indicated no drug excipient interaction. All the formulations were found to extend the drug release, while some of the formulation exhibited floating characteristics also.

From monoclinic Mg2B2O5 nanowires to triclinic Mg2B2O5:Eu nanorods
In this paper we report on the synthesis of single-crystal Mg2B2O5 nanowires by heating the precursor powder made of disodium tetraborate decahydrate and magnesium chloride dihydrate at 8500C. The as-received nanowires possess smooth surface with diameters varying between 25 and 40 nm. Also Mg2B2O5 nanorods doped with Eu were synthesized by firing a mixture powder of the above obtained Mg2B2O5 nanowires and Eu2O3 in air atmosphere. The as synthesized Mg2B2O5:Eu nanorods have diameters varying between 110 and 130 nm. The structural and compositional characteristics of the as-synthesized products have been investigated by XRD, SEM, TEM, EDX, and SAED techniques. Photoluminescence investigations reveal that both Eu+3 and Eu+2 can coexist in Mg2B2O5 nanorods. Eu2 display a violet emission beak at 412 nm and Eu3+ display broad emissions centered at 538 and 615 nm.

Geographic Information Systems (GIS) as Spatial Decision Support Systems (SDSS)
Recent advances in Operations Research (OR) and Information Technology (IT) have made it possible to integrate Operations Research techniques and Geographic Information Systems (GIS). This integration can be used for the development of Spatial Decision Support Systems (SDSS).There is an increasing need for incorporation of routing techniques into a Decision Support System (DSS) for making effective business decision making in transportation. GIS can be used to analyze the routes. Route analysis helps us to generate the most efficient route (best route / shortest route) that the vehicle should take between the company and it supply chain link. Alternative routes can also be generated and analyzed. Alternative routes help in rerouting of the supplies in case of problems (either man –made or natural) on one route. Travel speed is used as a proxy, to traffic data to calculate the time taken to reach from origin to destination by the shortest/best route. In this paper a spatial decision support system is developed for route generation.

Geometrics and architectural structure of our chin domes in Iran
Discovering the methods of constructing the domes, identification of different types of dome, studying the function of the structure, the strategies of drawing them, administrative works, as well as their related issues have been of special interest and concern of Iranian architects. Many valuable books, articles, and reports have been written in this field by Iranian architects. Thus, various types of dome such as rok, nar, and double-shelled have been introduced to the world and their functions have been investigated. In this architecture, ourchin dome, which is of typical characteristics of the tombs in southern part of Iran, has been neglected. Little information about this type of dome is available in the history of Iranian architecture. And this little information is limited to some reports and pictures from foreign tourists and unknown writers, including no more than a few names and dates of constructing of such structures. Therefore, the origin and the reason for the development of such domes as well as their role are still mysterious. The methodology of the current study is descriptive and analytical. In different parts of the present study, comparative, retrospective, and fieldwork studies have been used, whenever needed. In the current research, the root of the word, ourchin dome, and its meaning are pointed out. Also, the origin of Iranian architecture, which dates back to Seljuqid period, is introduced. Then, the geometric relationships of its sides are examined and different varieties of this dome [star and polygonal] are drawn. Studying the typology of the examples of this dome in Iran and Iraq revealed some remarkable points about the geometric, height, and shape of the dome, in addition to the number of its stories. Some factors, like the function of the crown, method of its construction, cover of the dome, and the system of the distribution of the load are clarified. Finally, by investigating the influential cultural and historical factors, we concluded that that the main reason for the development of the general structure of this type of dome was symbolic, not simply religious. This dome by its own or in combination with religious places has played an affective and functional role over time.

Growth and physiological attributes of wheat in Zn-contaminated soils
Zn-contaminated soils were rated for various levels of available (DTPA extractable) Zn viz. 0.42, 2.8, 4.5, 9.6 and 26.3 ppm and used to grow wheat (Tritium aestivum Linn.) plants. Effect of these soils on growth (length and dry matter production), visible symptoms of toxicity and biochemical constituents (protein, pigments and sugar contents and catalase activity) of wheat were evaluated. Plants grown at high Zn-contaminated soil (26.3 ppm) had visible symptoms of toxicity such as decreased growth, chlorosis and tip burning of young leaves and reduced leaf lamina. Length and dry matter yield of wheat were increased maximum at 4.5 ppm available Zn in soil. Pigment, sugar and protein contents were also stimulated upto 4.5 ppm of available Zn, whereas these values decreased with increase in Zn levels in soil. Antioxidative defense systems with respect to carotenoids and protein contents and catalase activity favoured the dry weight production in wheat which were grown at 4.5 ppm of available Zn in soil. Study revealed the tolerance of wheat found maximum at 4.5 ppm of available Zn in soil, where as tissue concentrations of root and shoot were 30.6 and 35.6 µg Zn g-1 of dry weight, respectively. High Zn concentrations (9.6 and 26.3 ppm) were not stimulatory to the wheat growth reduced biochemical constituents in cells and produced visible symptoms of toxicity in wheat.

Identification and ranking the factors affecting the performance of human resources; Case Study: Mellat Bank branches of Iran
Human resource managers and researchers believe that the human resource function plays an important role in the organization. In fact, most of annual reports assert that employees are the most important asset. Despite these beliefs, assumptions, opinions successive widespread, many organizational decisions of relatively low priority for human resources represents the organization and staffing. The study looked at factors affecting job performance of Mellat bank branches of Iran. First, by reviewing the literature, factors affecting job performance have been identified. The results showed that, ten factors can affect job performance in organizations. The next step is to test the factors identified in the Mellat Bank. For this purpose, a questionnaire designed and completed by the 184 bank executives in different areas of Tehran. After collecting data and analyzing, the results were obtained. In order to analyze the results, the Kolmogorov–Smirnov normality test, was done and then were analyzed using T-test assumptions. The results showed that, all the cases identified in the Mellat bank's job performance are impressive. In order to rank the importance of these factors Friedman test was used. The results showed that, from all factors, mental health of staff identified more effective from the view of job performance. According to ranking information obtained in the analysis, practical recommendations for the study was provided.
