Three months of Aedes aegypti control with a novel infusion bag formulation of Chilodonella uncinata in domestic water-storage container in Delhi

The efficacy of Chilodonella uncinata formulation, a naturally occurring protozoan biolarvicide, was evaluated in 40 liter domestic water-storage tub, one of the most common and preferred larval habitat of the dengue vector Aedes aegypti, in NCT Delhi. The formulation used contained base material as sterilized sand to entrap (3.5x10 cells/ml) of the active ingredient, wrapped in infusion bag in dosages (10.0g; 20.0g) introduced in large water-storage tub during September 2016. Test mosquito larvae were added as and when available during >7 weeks period and all supplied by wild mosquitoes laying eggs in another disused plastic container kept nearby. Inhibition of adult emergence (IE) was measured in Ae. aegypti both in experimental and untreated control tub. While all pupae formed in untreated control tub metamorphosed into adult; only one pupa managed to emerge as viable adult mosquito out of 9 pupae formed in treated experimental tub over 3 months follow-up period (September to December 2016), indicating IE in treated tub fluctuated between 75% and 100% for this period. Thus 30g formulation of this biolarvicide provided control of Ae. aegypti in water-storage tub during dengue transmission season in Delhi that normally extends from August to November.
Overlapping tracks processed by TIG melting TiC preplaced powder on low alloy steel surfaces

Abstract An overlapping composite track coating was produced on a steel surface by preplacing a 0·5 mm thick layer of TiC powder and then melting using a tungsten inert gas torch of constant energy input. The influence of the overlapping operation on preheating of the substrate, the dissolution of TiC particulates and the subsequent depth and hardness of the composite layer was analysed. The melt microstructure consisted of both undissolved and partially dissolved TiC particulates, together with a variety of morphologies and sizes of TiC particles precipitated during solidification. Preheating, resulting from the overlapping operation, occurred, producing additional melting of the TiC particulates and deeper melt depths but with a reduced volume fraction of TiC precipitates in the subsequent tracks. A maximum hardness of over 800 HV was developed in the composite layer. The high hardness was unevenly distributed in tracks melted at the initial and final stages, while it varied across the melt depths in other tracks.
Design and Numerical Analysis of Enhanced Cooling Techniques for a High Concentration Photovoltaic (HCPV) System

A thermal model has been developed to predict the heat output of a PV cell, in order to examine the most efficient and cost effective cooling system for a 500x concentrating PV cell. The worst case scenario (i.e. zero forced convection from a flat surface) was selected in order to identify and measure the scale of the challenge. Different geometries and materials of heat sinks were then designed and tested for passively cooling purposes of the High Concentration Photovoltaic system. It is shown that passive cooling of a CPV system with CR of 500x is insufficient to maintain the cells below 80°C, especially for high ambient temperatures. Numerical analysis and simulations in MatLAB and COMSOL Multiphysics report on the level of cell’s surface temperature and convective heat transfer coefficient that is required for the PV cell to operate below safe temperature limits.
Using CFD to improve the design of a circulating water channel

Computational Fluid Dynamics (CFD) has been used as a design tool to investigate means of improving flow uniformity in the working section of a circulating water channel. The CFD model was based on a 1/10 th scale wind-tunnel model of the circulating water channel at the Australian Maritime Hydrodynamics Research Centre (AMHRC). The CFD analysis was compared with experimental results obtained from the wind-tunnel model to validate the use of the CFD model. Three changes to the design were investigated; alteration of turning vane angle, increased resistance coefficient of a honeycomb screen and addition of trailing edge extensions to the turning vanes. The turning vane angle changes resulted in little improvement in flow uniformity. Increasing the resistance coefficient of the honeycomb screen resulted in improved uniformity, but at the expense of increased pressure loss. The addition of trailing edge extensions to the turning vanes resulted in the most significant improvements in flow uniformity. These results will be useful in selecting improvements to the circulating water channel.
Externalities of Education on Efficiency and Production Uncertainty of Maize in Rural Malawi

The paper looks at the existence, nature and form of intrahousehold and interhousehold externalities of education on efficiency and production uncertainty of maize in rural Malawi. Data from the Third Integrated Household Survey are used. I find statistically and economically significant positive intrahousehold and interhousehold externalities of education on both efficiency and production uncertainty, and that the intrahousehold externality effects are larger than interhousehold externality effects. Community level schooling is found to substitute for household level schooling in the sense that farmers who reside in households where members are not educated have relatively higher efficiency and lower production uncertainty on account of living in communities where some inhabitants are educated. The paper also finds that the intrahousehold and interhousehold externality effects are more pronounced for the least efficient farmers, and that they are monotonic, and largest when schooling is relatively low.

Address for Correspondence: Elangovan. M, Associate Professor, Department of Anatomy, Dhanalakshmi Srinivasan Medical College & Hospital, Tiruchi -Chennai Highway, Siruvachur, Perambalur, Tamil Nadu 621113, India. E-Mail: veera3071985@gmail.com. Background: Nutrient foramen is a natural opening in the shaft of a bone, allowing for passage of blood vessels into the medullary cavity. The knowledge of nutrient foramen is important in surgical procedures like bone grafting and more recently in microsurgical vascularised bone transplantation. Materials and Methods: This study was conducted in 173 long bones of the upper limb (55humerus, 59radius, 59-ulna). The number, location, size, position and direction of the diaphysis nutrient foramen in each of the long bones was noted. The foraminal index was also calculated using the Hughes formula. Results: In humerus single nutrient foramen was present in 84% of the bones, double nutrient foramina in 14% of the bones and had no nutrient foramina in 2% of the bones. The most common location of the nutrient foramina in humerus was in Antero medial surface, which was noted in 74% of the bones and in 89% of the bones the nutrient foramen was located in the middle third of the shaft of humerus. In radius, single nutrient foramen was found in 97% of the bones and double nutrient foramina were found in 3% of the bones. The most common location of the nutrient foramen in radius was on the anterior surface, which was noted in 72% of the bones and in 59% of the bones, the nutrient foramen was located in the middle third of the shaft of radius. In ulna, single nutrient foramen was found in 96% of the bones and double nutrient foramina were found in 2% of the bones and had no nutrient foramina in 2% of the bones The most common location of the nutrient foramen in ulna was on the anterior surface, which was noted in 76 % of the bones and in 68% of the bones the nutrient foramen was on the middle third of the shaft of ulna. Conclusion: The precise anatomical knowledge of the nutrient foramen of the long bones of upper limb is important for orthopaedic surgeons during surgical procedures like bone grafting, microsurgical bone transplantation.
Identification of Monetary Policy Shocks in Japan Using Sign Restrictions within the TVP-VAR Framework

This paper contributes to the discussion on the functioning of the monetary policy transmission mechanism in Japan during the past three decades. It extends the methodology of time-varying parameter vector autoregressions (TVP-VAR) by employing an identification scheme based on sign restrictions. This approach allows for an explicit account of the zero lower bound on the nominal interest rate. Results suggest differences in the transmission mechanism between the quantitative easing policy period and the periods when the call rate played the role of a monetary policy instrument. Monetary policy operating through call rate movements is found to influence output more than when it targets banks f balances held at the central bank. Monetary policy operating through quantitative easing is found to influence inflation, in sharp contrast to the previous literature.
Home Ownership and Unemployment: Does the Oswald Thesis Hold for Australian Regions?

In a series of papers in the late 1990s, Andrew Oswald explored the relationship between unemployment and home ownership. Oswald's conclusion was that a statistically significant positive relationship exists between changes in home ownership and the rate of unemployment. As a rough approximation, Oswald concludes that a , 5-percentage point increase in the rate of home ownership is associated with a one percentage point higher unemployment rate. Oswald's principal explanation for this result is that homeowners are less willing than private renters to move when they become unemployed as a result of high transaction costs. In this paper, we test the Oswald Hypothesis for Australian sub-regions using Australian Bureau of Statistics Census data for the period 1986 to 2001.

Planetary period oscillations in Saturn's magnetosphere: Examining the relationship between abrupt changes in behavior and solar wind‐induced magnetospheric compressions and expansions

We examine planetary period oscillations (PPOs) observed in Saturn's magnetospheric magnetic field data from the time of Saturn's equinox in 2009. In particular, we focus on the time period commencing February 2011, when the oscillations started to display sudden and unexpected changes in behavior at ~100–200 day intervals. These were characterized by large simultaneous changes in the amplitude of the northern and southern PPO systems, together with small changes in period and jumps in phase. Nine significant abrupt changes have been observed in the postequinox interval to date, commencing as the Sun started to emerge from a long extended solar minimum. We perform a statistical study to determine whether these modulations in PPO behavior were associated with changes in the solar and/or upstream solar wind conditions. We report that the upstream solar wind conditions show elevated values of solar wind dynamic pressure and density around the time of PPO behavioral transitions, as opposed to before and after these times. We suggest that abrupt changes in PPO behavior may be related to significant changes in the size of the Saturnian magnetosphere in response to varying solar wind conditions.
Trade Openness and Cocoa Output in Ondo State

The study was carried out to provide further evidence on the concept of openness by examining its effect on cocoa output and the direction of causality between cocoa output and identified variables of interest in Ondo state. Data collected for the period 1980 – 2012 was analyzed using the dynamic ordinary least square (DOLS) method. The study also applied the error correction method and conducted both stationarity and co-integration tests. Results showed that all the variables were non-stationary at level but stationary at first difference i.e 1(1). The co-integration test showed the existence of co-integration among the variables implying the existence of sustainable long run relationship among the variables of interest. The ECM also showed that 57% of changes in the short run toward long run will be corrected per year. The result of granger causality test showed the evidence of unidirectional causality between cocoa output in Ondo State and ratio of credit to private sector, which run strictly from cocoa output in Ondo State to the ratio of credit to private sector. It follows from the result that increase in cocoa output will serve as a positive indicator that will encourage lending to cocoa farmer and subsequently boost productivity. The study concluded that trade openness did not significantly influence cocoa output in the study area while domestic price was significant, though negative. The study therefore recommends that the government should ensure that cocoa farmers are adequately motivated by getting appropriate value for their cocoa output.

Empirical Investigation of Factors Influencing Faculty Followership's Perception of Institutional Leader in Malaysian Institutions of Higher Learning

This study aims at testing psychometric properties of the 32-item of Romance of Leadership Scale (RLS). The study is equally aims at investigating factors influencing faculty followership’s perception of institutional leader in selected Malaysian institutions of higher learning. Online survey questionnaires were conveniently sent to 2560 faculties of 16 public universities sampled, using guidelines of 95% confidence interval and margin of error at ± 02% to collect the data. A confirmatory factor analysis was performed to test factorial validity and psychometric properties of the three constructs underlie the faculty followership’s perception of institutional leader. It is anticipated that findings of the study will provide leaders of the institutions of higher learning with proper understanding of factors influencing faculty followership’s perceptions of institutional leaders, which is critical to organizational performance and faculty retention. Furthermore, it is expected that the findings will contribute to the initiatives of empirical studies on followership especially in higher education sector. The study as being the first of its kind in Malaysian context to empirically evaluate psychometric properties of the scales underlie faculty followership’s perception of institutional leader and investigate factors influencing faculty followership’s perception of institutional leader using well experienced participants rather than inexperience participants of the previous studies which sampled university students, high school and company employees would be a remarkable contribution to the followership literature.
Association between Vascular Endothelial Growth Factor (VEGF) -1154G/A Polymorphism and Endometriosis in North West of Iran

Endometriosis is considered as a multifactorial disease that affects up to 10% of all women of fertile age. Vascular endothelial growth factor (VEGF) is one of the most important activators of angiogenesis. VEGF is known to be a key molecule in the pathogenesis of endometriosis. A great number of studies have referred to genetic polymorphisms as a factor that contributes to the development of endometriosis. The present study was aimed to find out the frequency of the VEGF -1154G/A polymorphism and its relationship with endometriosis risk in Iranian women with endometriosis.This study involved 175 patients with endometriosis and 131 healthy controls. Following extraction of genomic DNA from patients and controls, genotyping of the -1154G/A polymorphism of the VEGF gene were performed by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) analysis. Multivariate analysis was used to examine the association between the risk of endometriosis and VEGF -1154G/A polymorphism. There was statistically a significant difference in the frequency of the -1154G/A polymorphism between patients and the controls. The percentage distribution of the three -1154G/A genotypes was (GG 3.4%, GA %46.8%, AA 49.7%) in endometriosis patients. Conclusion : Data supports the hypothesis that angiogenesis is of pivotal importance in the development of endometriosis. Our study indicates that there is significant association between the VEGF gene -1154G/A polymorphism and the risk of endometriosis in North West of Iran.
Selected mechanical properties of thermally modified American ash wood.

The compressive strength and bending strength along the grains as well as the elasticity modulus of American ash wood were determined for thermally modified samples and unmodified samples at the moisture content of 6%. Thermal modification of wood was shown to lead to a decrease in all mechanical parameters measured. The reduced values of mechanical parameters of modified wood could be only partly explained by its decreased density as a result of thermal treatment. As followed from the results, specific strength and specific elasticity modulus were better indicators of thermal degradation of wood than its absolute mechanical
Corporate Governance Mechanisms and Performance of Public-Listed Family-Ownership in Malaysia

The study examines the relationship of corporate governance mechanisms and performance between family and non-family ownership of public-listed firm in Malaysia from 1999 through 2005 as measured by Tobin’s Q, ROA and ROE. The findings show that on average, family ownership experiences a higher value than non-family ownership based on ROE. On the other hand, based on Tobin’s Q and ROA, the study finds that firm value is lower in family than non- family ownership. In addition, the corporate governance mechanisms such as the board size, independent director and duality for family and non-family ownership has a strong significant influence on firm performance.
Family influence on internationalization: an analysis of risk acceptance

This article aims to contribute to the literature on family business (FBs), particularly from the perspective of commitment and influence of family on the FB internationalization regarding risk acceptance. Qualitative in nature, the study involved the use of a single longitudinal case study, based on in-depth interviews, storytelling and secondary data. Primary data were collected through semi-structured personal interviews with the company’s board chairman and vice-chairman, commercial director, European director and export manager; and secondary data were obtained using documental and scientific sources. It could be seen that family commitment and ownership influenced the internationalization process due to the proactivity of its European descendant founders, and particularly because in this company studied the process was initiated by a non-family member. However, family participation encourages risk acceptance, since the attachment to the family business creates an eagerness for growth. The findings corroborate the characteristics proposed by the Uppsala School, which claims that internationalization occurs in an unplanned, opportunistic manner, following sequential phases, through incremental learning and via the establishment of networks.
Gross And Microscopic Changes In The Gonads Of Male And Female Domestic Pigeon (Columbia Livia)

The study was undertaken to observe the gross features of the male and female pigeon as well as the behavioral patterns and histological features of their gonads with the aim of establishing their sexual characteristics as a mode of identifying their sex. Seven pairs of pigeon age at 1, 2, 4, 11, 12, 13 and 14 weeks were purchased from local breeders and reared under controlled conditions before they were used in this study. A pair of bird was sacrificed at a time after body weights were recorded. The gonads were then dissected out and weighed wherever possible before being subjected to histological studies using routine Haematoxylin and Eosin (H & E) staining technique. Grossly, the colour pattern and feather did not show any obvious difference between the male and female. A pair consists of male and female. A male weighed more (120g at one week and 360g at week fourteen) than the female (90g at week one and 250g at week fourteen). On dissection, male presents two testes while the female present only one ovary on the left side. By 4 th week the male began to show more aggressive behavior than the female on "beak tests" recorded for the first time in the present study. Histologically, the male pigeon showed well developed testes from 11 weeks onward with the seminiferous tubule, straight tubule and interstitial cells of leydigs in it. The ovaries in the females could be recognized with follicles in them by 4 weeks of age. The follicles became very prominent and large by 11 weeks and the Graafian follicles could be recognized by 13 weeks of age. It was concluded from the above observation that within a set of pairs, the large one could be safely considered as the male and it will be more aggressive than its female counterpart. Histologically, the birds seem to show sexual maturity by 11-12 weeks with females ovulating by 13 weeks. It is therefore safer to buy pigeons in pairs of the same age from a renowned breeder than in the market for breeding purpose. (New York Science Journal. 2010;3(10):108-111). (ISSN: 1554-0200).
