Design of Multi-standard Low Noise Amplifier based on Active Inductor

A current-controlled multi-standard low-noise amplifier (LNA) has been proposed based on the active inductor. The novel folded-cascode circuit topology with feedback resistance ensures good quality factor and linearity of the active inductor. The current-controlled inductance makes the LNA work well with various wireless communication standards such as TD-SCDMA, CDMA2000, WCDMA and Bluetooth. Simulation results indicate that the multi-standard LNA designed using 0.18 μm CMOS technology has a high gain (>11.6 dB), low noise figure (<1.851 dB), good input impedance matching (<-54.01 dB) and stable output impedance matching (<-26.78 dB).

Time Management between Family and Career among Women Lecturer at Polytechnic

The involvement of women's career has shown that women nowadays are moving steps towards a different change than women in earlier times. Looking at the current progress and the rising cost of living in nowadays, many of the women involved with the world of work. The involvement of marriage women in the workforce has invite various of conflicts and challenges that have been subjected. Because of this, it is desirable for the authors to conduct a more detailed about the challenges faced by career women in managing their time between their family and career. The objectives were to identify the challenges faced by women lecturers in the field of technical and vocational education in managing the household, to review the criteria required by the women on the go to improve performance in career and family management and to identify the best way or approach in balancing responsibilities between career and family life for women lecturer at polytechnic. A quantitative approach in the form of a correlational study was adopted for this research. 76 questionnaires were distributed to the respondents Politeknik Merlimau, Melaka. The results for all criteria of the organization, job satisfaction, attitudes and opportunities show positive results. This means that overall respondents agreed with all of these criteria can improve performance in a career. In conclusion, based on the findings clearly show that women lecture had no problems in balancing their roles in a career and a family.
On the relationship between economic rent and profit

The question of who appropriates the economic rents created by resources and capabilities has remained largely unresolved in strategic management. The aim of this paper is to highlight the problem established strategic management theory faces in explaining value appropriation, and to propose a framework that addresses how R&C affect bargaining power and value appropriation. While resource-based theory focuses on the generation and sustainability of economic rents, the appropriation factor framework presented in this paper shows that particular resources and capabilities, termed appropriation factors, affect bargaining power, and thus the possibility for economic agents of appropriating a larger share of rents. Based on this framework, it is argued that investments in heterogeneous and immobile appropriation factors that facilitate value appropriation through elevated bargaining power can constitute an alternative avenue to sustained competitive advantage.

The effect of dietary phytase on broiler performance and digestive, bone, and blood biochemistry characteristics

The dietary inclusion of phytase increases nutrient and energy bioavailability for broilers. The effect of phytase increases nutrients and energy bioavailability for either the objective of this experiment was to evaluate the influence of nutrient and energy reduction in diets supplemented with phytase on the performance, gastrointestinal pH, organ and bone composition, and blood biochemistry of broilers between eight and 21 days of age. In the study, 1.120 male Cobb 500(r) broilers, with 161±1g average weight, were used. At eight days of age, birds were distributed according to a completely randomized experimental design with seven treatments in a 3x2+1 factorial arrangement with eight replicates of 20 broiler each. Treatments corresponded to reduction of calcium (Ca) and phosphorus (P), amino acids and energy, or reduction of Ca, P, amino acids and energy; supplementation or not of phytase; and a positive control treatment. Broiler fed the diet with reduced Ca and P levels and phytase supplementation presented the best performance of all groups. The diet with reduced amino acid and energy levels and phytase addition reduced gizzard and proventriculus pH. Dietary Ca and P reduction increased relative liver and heart weights, as well as albumin blood levels. The bones of broilers fed phytase-supplemented diets presented higher ash content.
Shaping Young Women for the Future: A Case Study of a South African Girls’ School

This project seeks to examine the place of private schools in preparing young women for a future in the new South Africa. Specifically, this project focuses on high school learners at South African Girls’ School (SAGS) in Durban, South Africa. By examining ways of learning, succeeding and fitting in at SAGS as well as perceptions of a democratic South Africa and how the learners at this school see themselves fitting into the future of their country, we gain a fuller understanding of what it means to be a citizen of this country for a group that is not often studied. By looking at certain aspects of everyday life at SAGS, we can see how the hidden curriculum of the school shapes girls’ understandings of themselves, each other and their country. As is always the case in South Africa, race remains a salient issue. By looking at where there is integration and where there is separation, we can begin to understand which divisions within society will be the most durable. As most of the existing literature argues, at SAGS it is clear that racial segregation still exists and is institutionalized; however, most students are able to find a way to feel at home and comfortable within the institution. Through this work of understanding how young girls are shaped by (but also play an active role in shaping) the institution in which they have spent most of their lives, important information is added to the literature on what it means to grow up in a transforming South Africa.

Disentangling the Threads: Analysing Synchronous Online Discussions

This paper investigates features of synchronous chat-communication within a postgraduate e-learning programme that is rooted communities of enquiry (Lave & Wenger, 1991). This project, funded by the Scottish Government, was to provide staff development for teachers throughout Scotland. The paper considers approaches to making sense of disparate threads of online chats between tutors and students and methodological issues in identifying the appropriate unit of analysis. The framework for analysis was derived from promotion of a community of enquiry perspective (Garrison, 2007; Garrison & Vaughan, 2008) which emphasises the importance of the intersection of social, cognitive and teaching presence for achieving shared learning goals. A quantitative content analysis of transcripts from tutor led group chats was used to determine frequencies of teaching presence, social presence, and cognitive presence indicators. Results show that overall, 70% of the contributions were coded as facilitating cognitive discourse. This finding builds on previous research by Ortiz-Rodriguez et al. (2005) which suggests that instructors can influence cognitive presence within synchronous chat. It is suggested that the community of learning enquiry has the potential to help identify critical points for encouraging cognitive presence within synchronous chats. In addition, the study has implications for the growing number of guidelines for the design of online learning environments, particularly in terms of the extent to which synchronous chats have potentially underestimated the value of synchronous learning environments in supporting deeper, critical thinking and shared reflection among learners.
A New Occupational/Industrial Coding System for 19th Century U.S. Heavy Industrial Workers

Many census occupational classification systems have been developed over the last 150 years. Availability of digital census data sets now means such classifications can be systematically analyzed. Examination of heavy industrial workers in the full count U.S. 1880 census, and other censuses, has revealed major problems in the attribution of occupations to industrial sectors. This is traceable to the original enumeration process, and it particularly affects generic tradesmen such as blacksmiths and carpenters, who worked in numerous industrial sectors. As a result, the imputation of industrial sector codes from recorded occupations by the North Atlantic Population Project (NAPP) is substantially in error, suggesting that re-coding of existing census records using non-census sources would be necessary for such industrial sector codes to have empirical validity. A new occupational/industrial coding system, incorporating the NAPP-modified HISCO scheme, is presented. This system is capable of supporting both future re-coding work, in a structured data warehouse environment, and the systematic coding of occupational data from a range of archival sources such as company records and city directories.
Synthesis, Characterization and Comparisons of Mechanical and Tribological Behaviour of Ortho and Meta Cresol Novalac Epoxy Resin

In this study ortho and meta cresol novalac epoxy resins were synthesized to study their mechanical and tribological behaviour under dry sliding conditions. The friction and wear tests were carried out on a pin on disc apparatus under applied normal load of 10, 20, 30 and 40 N and different sliding velocity of 0.9, 1.8, 2.7 and 3.6 m/s respectively. To evaluate mechanical properties of these synthesized novalac epoxy resins the tensile, flexural and compression tests have been carried out. It is found that in both novalac epoxies the coefficient of friction decreases with increase in the applied normal load and increases with increase in the sliding velocity where as specific wear rate increases with increase in the applied normal load and decreases with increase in the sliding velocity. It is also found that the mechanical properties of the ortho cresol novalac epoxy resins showed better results in comparison to the meta cresol novalac epoxy. The morphology of these novalac epoxy is studied with the help of (SEM) scanning electron microscope.
Association between serum lactate and postoperative outcomes following coronary artery bypass graft surgery

: Background: Increased serum lactate during cardio-pulmonary bypass is associated with high mortality and cardiac complications up to 10-20 percent. The aim of this study was to evaluate the effect of serum lactate increase on postoperative outcomes after coronary artery bypass graft (CABG) Surgery. Materials and Methods: This descriptive-analytical study was performed on cases (no=116) undergoing CABG at Beheshti hospital in Kashan between 2013-2014. Demographic data, variables related to surgery, serum lactate level and the time of tracheal extubation, length of stay in intensive care unit (ICU) and hospital post-surgery left ventricular ejection fraction were collected. These data was compared in two groups: Normal serum lactate (< 2 m mol\liter) and Hyperlactatemia (> 2 m mol\liter) group. Results: The postoperative hyperlactatemia was observed in 62.1 % of patients. There were no significant differences between two groups in time of tracheal extubation, length of stay in ICU and hospital. There was a relationship between the mean postoperative serum lactate and blood sugar, bicarbonate, pH, length of cardiopulmonary bypass and the aortic cross clamping time. There was a significant relationship between the serum lactate increment and the left ventricular ejection fraction decrement. Conclusion: Hyperlactatemia is probably associated with such important factors as high blood sugar, longer duration of aortic cross clamp and cardio-pulmonary bypass time. So controlling such factors can reduce the rate of hyperlactatemia and help postoperative recovery.
Patterns and Determinates of Farm Households' Investment in Rural Ethiopia: The Case of East Hararghe Zone, Oromia National Regional State

This study empirically examines the determinants of investment activities of 700 samp le respondent farm households in East Hararghe Zone of Oro mia regional state in Ethiopia applying tobit model. A mult istage sampling technique and probability proportional to size (PPS) random samp ling technique was used to select the respondent households. The result of the analyses shows that 71.9% of the entire sample households had investment in different forms and intensity with the average amount of 6311.91 Birr in the study year. The patterns of their investments were on livestock production, land development, productive farm assets, family education, khat plantation, and small industry and business developments. The results of the econometric analysis reveal that sex o f household head, household size, dependency ratio, livestock ownership, farm inco me, access to road, training participation, investment incentives, contact with development agents, corruption, objective of investment, and inflat ion perception of household head were found to significantly influence the willingness probability and intensity of capital use for investment among the sample households. The findings of the study calls for formal institutions to support and utilize farm households' investment achievements as an engine for overall development of the country in general and rural areas of the country in particular.
Electrophysiological status of sural nerves in type 2 diabetes mellitus patients before symptomatic peripheral neuropathy

Introduction. Neuropathies in type 2 diabetes mellitus (T2DM) patients are well known. However, electrophysiological changes in their peripheral nerves, particularly before overt peripheral neuropathy have received much less attention. Hence, we aimed to study the electrophysiological status of bilateral sural nerves in T2DM patients who do not show symptoms and signs of peripheral neuropathy. Material and methods. We selected 35 T2DM male patients and 35 age- and sex-matched control subjects without any clinical evidence of peripheral neuropathy and infectious, systemic, metabolic, and neuropsychiatric illnesses after informed written consent. Nerve conduction study (NCS) of bilateral sural nerves of both the groups was done at the lab temperature of 26 ± 2oC by antidromic method of stimulation using standard methods. Their latency, conduction velocity, amplitude, and duration of bilateral sural sensory nerve action potentials (SNAPs) were measured and compared. Results. T2DM patients had reduced amplitudes of bilateral sural SNAPs compared to control subjects [left (12.46 ± 3.77) μV vs. (16.42 ± 4.58) μV, p = 0.000; right (11.96 ± 4.45) μV vs . (16.62 ± 6.20) μV, p = 0.001] though they were above the normal cut-off value of ≥ 4 μV. T2DM patients showed prolonged durations of bilateral sural SNAPs compared to the control subjects [left (1.99 ± 0.38) ms vs . (1.67 ± 0.27) ms, p = 0.000; right (1.92 ± 0.47) ms vs . (1.55 ± 0.33) ms, p = 0.000]. Conclusion. Reduced amplitudes and prolonged durations of bilateral sural SNAPs are the electrophysiological alterations, suggestive of peripheral neuropathy, in T2DM patients that appear before they show clinical symptoms and signs of peripheral neuropathy.
Classification of Micro Array Gene Expression Proposed using Statistical Approaches

Classification analysis of microarray gene expression data has been performed widely to find out the biological features and to differentiate intimately related cell types that usually appear in the diagnosis of cancer. Many algorithms and techniques have been developed for the microarray gene classification process. These developed techniques accomplish microarray gene classification process with the aid of three basic phases namely, dimensionality reduction, feature selection and gene classification. In our previous work, microarray gene classification by statistical analysis approach with Fuzzy Inference System (FIS) was proposed for precise classification of genes to their corresponding gene types. Among various dimensionality reduction techniques, the paper proposed prescribed statistical procedures to efficiently perform the classification process. To further substantiate and to analyze the performance, we conduct a comparative study in this work. The comparative study considers two popular dimensionality reduction techniques called Principle Component Analysis (PCA) and Multi-linear Principle Component Analysis (MPCA). The dimensionality reduction techniques replace the proposed statistical approach and perform microarray gene expression data classification. Based on the obtained results, we conduct the performance study over the combination of statistical approach with FIS, LPP with FIS and MPCA with FIS. The study results that the statistical approach with FIS outperforms the classification performance when compared to the other methods.
Relationships Between Temperature, pH, and Crusting on Mg/Ca Ratios in Laboratory‐Grown Neogloboquadrina Foraminifera

Author(s): Davis, CV; Fehrenbacher, JS; Hill, TM; Russell, AD; Spero, HJ | Abstract: ©2017. American Geophysical Union. All Rights Reserved. Mg/Ca ratio paleothermometry in foraminifera is an important tool for the reconstruction and interpretation of past environments. However, existing Mg/Ca:temperature relationships for planktic species inhabiting middle- and high-latitude environments are limited by a lack of information about the development and impact of low-Mg/Ca ratio “crusts” and the influence of the carbonate system on Mg/Ca ratios in these groups. To address this, we cultured individual specimens of Neogloboquadrina incompta and Neogloboquadrina pachyderma in seawater across a range of temperature (6°–12°C) and pH (7.4–8.2). We found by laser ablation inductively couple mass spectrometry analyses of shells that culture-grown crust calcite in N. incompta had a lower Mg/Ca ratio than ontogenetic calcite formed at the same temperature, suggesting that temperature is not responsible for the low-Mg/Ca ratio of neogloboquadrinid crusts. The Mg/Ca:temperature relationship for ontogenetic calcite in N. incompta was consistent with the previously published culture-based relationship, and no significant relationship was found between Mg/Ca ratios and pH in this species. However, the Mg/Ca ratio in laboratory-cultured N. pachyderma was much higher than that reported in previous core top and sediment trap samples, due to lack of crust formation in culture. Application of our ontogenetic calcite-specific Mg/Ca:temperature relationships to fossil N. pachyderma and N. incompta from five intervals in cores from the Santa Barbara Basin and the Bering Sea shows that excluding crust calcite in fossil specimens may improve Mg/Ca-based temperature estimates.
Numerical Analysis of Two Phase Flow Boiling Heat Transfer through Micro-Channel

Day by day rapid miniaturization of electronics devices in electronic industry have resulted in continuous raise of heat removal requirements for making the more efficient the electronic devices, thereby making a call for highly thermal efficient cooling technology. Two phase flow boiling heat transfer is the one of the potential solution for heat dissipation for electronic devices. For highly efficient performance and reliability of micro-electronic and mechanical systems (MEMS) devices, the working temperate should be keep below some specific temperature less than 90 °C. The purpose of the work is to develop a numerical model to predict the behaviour of two phase forced convection in micro-channels using de-ionize water (DIW) as the coolant with uniform heat flux in laminar and turbulent flow regime. A 1-D thermal-hydraulic homogeneous equilibrium model (TH-HEM), consisting of mass, momentum and energy conservation equations and empirical correlation for laminar and turbulent flow, and properties of substance equation as dryness fraction relation with liquid and vapour density, are solved numerically using a finite-difference upwind scheme for single as well as two phase flow and algebraic equations. Finally, the TH-HEM model is used to evaluate the location of boiling front, it’s variation with uniform input power, Variation in dryness fraction in two phase region, pressure distribution of fluid along the axial length, wall and fluid temperature distribution along the axial length, for one fixed inlet temperature and fixed outlet pressure condition.

Academic Resilience in Mathematics among Poor and Minority Students

Based on national data from the Prospects study, we identified the individual characteristics that distinguished academically successful, or resilient, elementary school students from minority and low-socioeconomic-status (SES) backgrounds from their less successful, or nonresilient, counterparts. We also formulated and tested 4 models of the risk factors and resilience-promoting features of schools: (a) effective schools; (b) peer group composition; (c) school resources; and (d) the supportive school community model. Our results suggested that minority students from low-SES backgrounds were exposed to greater risks and fewer resilience-promoting conditions than otherwise similar low-SES White students. Results, though, generally supported the applicability of uniform individual- and school-level models of academic resiliency to all low-SES students, regardless of their race. Greater engagement in academic activities, an internal locus of control, efficaciousness in math, a more positive outlook toward school, and more positive self-esteem were characteristic of all low-SES students who achieved resilient mathematics outcomes. The most powerful school characteristics for promoting resiliency were represented by the supportive school community model, which, unlike the other school models, included elements that actively shielded children from adversity.
Usage of Proxy Based Framework in Cloud Computing Environment

Cloud computing is the product of the synthesis of traditional computing technology and network technology like parallel computing, distributed computing. The main goal of cloud computing is to construct a perfect system with powerful computing capability through a large number of relatively low cost computing entity using the advanced business models like SaaS, PaaS, IaaS to distribute the powerful computing capability to end users. A proposed proxy-based multi cloud framework using Cloud Proxies allows dynamic collaborations without pre established collaboration agreements or standardized interfaces. The recent surge in cloud computing arises from its capability to provide software, infrastructure, and platform assistance without requiring large investments or outlay to manage and operate them. Clouds typically require service providers, infrastructure/resource providers, and service users (or clients). They incorporate applications delivered as services, as well as the hardware and software systems presuming these services.
