Fruit composition of organically and conventionally cultivated strawberry 'Polka

The aim of this study was to elucidate the effect of cultivation technology and plant age on fruit composition of strawberries (Fragaria x ananassa Duch.) 'Polka'. Strawberry fruits from two- and three­year-old plantations were harvested on two conventional and two organic farms in South Estonia in 2008. Content of fruit dry matter (DM), ascorbic acid content (AAC), soluble solids content (SSC), titratable acidity (TA), anthocyanins (ACY) and total antioxidant capacity (TAC) were recorded. The results indicate that the strawberries cultivated under organic farming conditions had higher SSC and contained more fruit DM, compared to the conventionally grown strawberries. Content of ACY and SSC was significantly influenced by plant age.
Direct meso-scale simulations of fibres in turbulent liquid flow

A procedure for direct, meso-scale simulations of flexible fibres immersed in liquid flow is introduced. The fibres are composed of chains of spherical particles connected through ball joints with the bending stiffness of the joints as a variable. The motion of the fibres and the liquid is two-way coupled with full resolution of the solid-liquid interface. First the simulation procedure is validated by means of an analytical solution for sphere doublets in zero-Reynolds simple shear flow. Subsequently we use the numerical method to study inertial flows with fibres, more specifically the interaction of a fibre with isotropic turbulence.
Assessing the driving forces for greening business practices: Empirical evidence from the United Arab Emirates’ logistics service industry

The uprising economic, social and political pressures on achieving a good level of environmental governance have forced companies to adopt business practices that aim to mitigate CO2 emissions. Logistics industry is considered as one of the major areas that could make a considerable improvement in reducing the environmental impact of business activities. The aim of this study is to investigate the driving forces that influence the adoption of environmentally friendly logistics activities. Following a detailed literature review, a theoretical model, which encompassed several driving forces and logistics activities, has been developed. Survey-based quantitative data were collected from logistics service providers in the United Arab Emirates (UAE) and analysed using structural equation modelling methodology and multiple regression analysis. Through answering 110 questionnaires, respondents holding different managerial levels at logistics service organizations, provided data reflecting their perception of the forces that would influence the adoption of green logistics practices. The driving forces (legislations, customers, and organizational awareness) were found to influence the adoption of green logistics practices by the logistics service industry in the areas of warehousing, packaging and transportation.
IMPACT OF TWO TYPES OF SODIUM AND ULTRA FILTRATION PROFILES ON INTRADIALYTIC HYPOTENSION IN HEMODIALYSIS PATIENTS

BACKGROUND : Intradialytic hypotension is the most common complication of haemodialysis (HD) and the main cause for patient’s dissatisfaction. One of the new preventiv e methods for it is the use of sodium profile and u ltrafiltration (UF) profile. This study was designed to evaluate the effec t of two types of sodium and UF profile on intradia lytic hypotension. METHODS : In this cross-sectional study, 26 stable HD patien ts from two dialysis center in Isfahan city, underw ent three treatments in 3 dialysis sessions: 1. control, cons tant dialysate sodium concentration of 138 mmol/l with constant UF; 2. linear sodium profile + UF profile (type 1), a line arly decreasing dialysate sodium concentration (138 ‐146 mmol/l) combination with a linearly decreasing UF rate; and 3. s tepwise sodium profile + UF profile (type 2), a ste pwise decreasing dialysate sodium concentration (138‐146 mmol/l) combination with a stepwise decreasing UF rate. Data wer e analyzed via SPSS-14 by using χ2 test. RESULTS : In this study a total of 26 patients were particip ated with the mean age of 46.8 ± 19 years. In each group, 78 dialysis sessions and a total of 234 dialysis session s were analyzed. The incidence of intradialytic hyp otension was significantly reduced during two type of profiles compared with control (p 0.05). DISCUSSION : Sodium and UF profile is simple and cost effective methods that modulates the dialysate sodium and ult rafiltration rate, and preserve the homodynamic status o f patients during dialysis. This method can reduce the incidence of intradialytic hypotension.
Seeking Similarity: How Immigrants and Natives Manage in the Labor Market

We investigate how the interplay between manager and worker origin affects hiring patterns, job separations, and wages. Numerous specifications utilizing a longitudinal matched employer-employee database including 70,000 establishments consistently show that managers are substantially more likely to hire workers of their own origin. Workers who share an origin with their managers earn higher wages and have lower separation rates than dissimilar workers, but this pattern is driven by differences in unobserved worker characteristics. Our findings indicate that the sorting patterns are more likely to be explained by profit-maximizing concerns than by preference-based discrimination.

IDENTIFICATION AND COMPARISION OF FUNGI FROM DIFFERENT DEPTHS OF ANCIENT GLACIAL ICE

Dr. Scott Rogers, Advisor Glacial ice serves as a unique preservation matrix for contemporary and ancient microorganisms. The main objective of this study was to evaluate and test the existence of the fungi encased in ancient glacial ice of Antarctica and Greenland. PCR (polymerase chain reaction) amplification was used to isolate the DNA followed by DNA sequencing to obtain the DNA sequences of the ancient microorganisms. Most of the sequences obtained from ancient microbes were similar to the contemporary fungi. Few fungi cultured were approximately 10,000 years old. Microorganisms isolated from ancient glacial ice have undergone repeated phases of evolutionary changes, such as irradiation, freezing and thawing, and in the process they have been archiving various biogenic materials over the period of time. These microorganisms entrapped in glacial ice provide valuable information about the evolutionary processes, as well as the rich biodiversity during ancient times. Hence, various species of microorganisms may appear to be extinct, but factually they might be dormant, entrapped in ice for millions of years and are capable to reappear amidst suitable conditions. The results of this study can be used in future to relate the biological, biogeochemical and genetic composition to a unique and well characterized geologic history of the fungi entrapped in ancient glacial ice.
Distance-dependent Models for Predicting the Development of Mixed Coniferous Forests in Finland

Distance-dependent growth models and crown models, based on extensive material, were built for Scots pine and Norway spruce growing in a mixed forest. The crown ratio was also used as a predictor in a diameter growth model to better describe the thinning reaction. The effect of crown ratio on the growth dynamics was studied in simulation examples. Monte Carlo simulation was used to correct the bias caused by nonlinear transformations of predictors and response. After thinnings the crown ratio as a predictor was found to be a clear growth-retarding factor. The growth retarding effect was stronger among pines with thinnings from below, whereas the estimated yield of spruces over rotation was slightly greater when the crown ratio was included than without it. With each type of thinning the effect of crown ratio on pine growth was almost the same, but the growth of spruces was clearly delayed when the stand was thinned from above. Simulation examples also showed that it is profitable to raise the proportion of spruces during rotation, since spruces maintain the growth more vigorous at older ages. The total yield during 90 years rotation was about 20 % higher if the stand was transformed into a pure spruce stand instead of pine.
Effects of age, years of schooling, income, and cash incentive on postponement of first pregnancy among newly married couples in Satara district of Maharashtra (India)

Context: Postponement of first pregnancy is known to be associated with a variety of interdependent factors such as age, education, income, occupation, religion, caste, and cash incentives. This paper examines the relationship and effects of some of these factors on postponement of first pregnancy among newly married couples in Satara district. Objective: To study the interdependency of age, years of schooling, income, and cash incentive on postponement of first pregnancy among newly married couples. Materials and Methods: This study employed quasi-experimental study design. Duly trained multipurpose workers interviewed husbands and auxiliary nurse midwives (ANMs) interviewed the wives; preferably in separate rooms using pretested semi-open proforma. Statistical analysis was done using STATA® version 12 statistical software. Results: Out of 1,355 participants; 704 couples successfully postponed first pregnancy by 2 years, but 651 couples could not do so. Participants were significantly successful in postponing pregnancy by 569.13 vs. 353.89 days for controls. Age and education of female participants were significantly associated with postponement of first pregnancy; while age, education, and income of male participants were not associated with postponement. Conclusions: Higher age, more education, and higher income appear to be associated with acceptance of postponement of pregnancy and appear to be acting synergistically in both male and female participants as compared to nonparticipants.
Decoupling and matching network for a MIMO handset antenna

This thesis studies existing methods to derive decoupling and matching lumped element networks for antenna arrays. Based on the results, one method is used to design a decoupling and matching network for a 4 × 4 MIMO handset antenna. the complete antenna together with realistic lumped elements is simulated and, for the first time, realized in practice in a mobile phone antenna decoupling more than two antennas. The selected design for the decoupling and matching network is merely a starting point for the work. The network is reduced in order to manufacture it on a single layer PCB. Furthermore, several optimization steps are taken to derive the final values of the network elements. The MIMO array is designed at 2.6 GHz–2.7 GHz band and the measured total efficiencies vary between 32.6% and 62.5%. However, the efficiencies could potentially be 49.9%–62.7% according to the simulations. The difference is most likely due to excessive amount of solder for joining the components and other manufacturing defects. In simulations, decoupling and matching networks operate significantly better than conventional input matching networks. The difference varies from 5.7 percentage points to 16.5 points. These results demonstrate, that decoupling and matching networks are a potential choice, when strong mutual coupling is present in an antenna array. Furthermore, these networks provide an alternative approach to the issue of coupling.
Retrieving Slowness Distribution of a Medium between Two Boreholes from First Arrival

We study a problem of reconstruction of seismic wave speed distribution from a set of measured first arrival traveltimes in presence of strong velocity contrasts, which cause the problem to be highly non-linear. In this context, we make an attempt to improve a stable iterative reconstruction algorithm by incorporating appropriate a variable regularizing parameter and also used it for a simple synthetic borehole test after writing its algorithm in a C++ code. The simulations results support the effectiveness of the method. Keywords—Inverse Problems, Ill-Posed Problems, Nonlinear Programming, Seism T ic omography.
Underutilization of Cultural Heritages for Tourism Due to Poor Entrance Fee Determination Based on the Travel Cost Framework

Tourism is one of the world’s fastest growing industries and is one of the largest industries in the world. Cultural tourism is often argued to be one of the most important and rapidly growing areas of global tourism. Ethiopia, a country in East Africa can be expressed as a mosaic of people and cultures, encyclopedia of geology, the cradle of humankind and civilization. The natural and interesting landscape, endowed with rich biodiversity, socked in history, culturally hospitable, traditionally sensitive, and intrinsically religious people put together Ethiopia a tourist paradise though the entrance fee, the value and other characteristics of these heritage resources are left unaddressed . The study uses the Individual Travel Cost Method to estimate the use value of RHCL. The truncated negative binomial method (TNBM) was employed to derive the demand function for use value of RHCL. The result of the study showed that the potential annual use value of the RHCL was estimated to be 759,687,113 ETB per annum [1] . Furthermore; the entrance fee that would maximize the use value of the church is 11.32 US Dollars per four days. which has a significant difference from the existing entrance fee(50 US Dollars per four days) . Future researches are recommended. Keywords: Individual travel cost method; cultural Heritage; economic value [1] 1 US Dollar=19.3469 of Ethiopian Birr(ETB) while the study is conducted

The Combined Effects of Response Time and Message Content on Growth Patterns of Discussion Threads in Computer-Supported Collaborative Argumentation.

This study examined the effects of response time and message content on the growth patterns of discussion threads in computer-supported collaborative argumentation. Event sequence analysis was used to measure response times between threaded messages and responses containing arguments, evidence, critiques, evaluations, and other comments from online debates. The results supported and contradicted the findings of Hewitt and Teplovs (1999). Response rates overall declined at a rate of 17% per day in wait time across all message categories. On the other hand, the posting of critiques and particular types of argumentative exchanges produced higher response rates of . 72 and higher, and their average wait times of 1.04 days were significantly longer than those of other message types. The debate format and use of message labels may have produced sufficient argumentative exchanges to produce high response rates despite the long response times, which in turn helped sustain the growth of discussion threads. L’etude examine les effets du temps de reponse et du contenu du message sur les modeles de croissance du volume des discussions dans l’argumentation collaborative assistee par ordinateur. L’analyse sequentielle des evenements a ete utilisee pour mesurer les temps de reponse, i.e. le temps entre les messages envoyes et les reponses recues qui contenaient des arguments, des preuves, des critiques, des evaluations et d’autres commentaires issus des debats en ligne. Les resultats ont appuye et contredit les resultats de Hewitt et Teplovs (1999). D’une part, le rythme des reponses a diminue dans l’ensemble, a un taux de 17 % par jour en temps d’attente dans toutes les categories de message. D’autre part, les articles de critique et d’argumentation ont produit des taux de reponse plus eleves, soit de 72 % et plus, et leur temps d’attente moyen, 1,04 jours, etait nettement plus long que celui des autres types de message. Il est possible que la formule debat et l’utilisation de labels pour identifier les messages aient produit suffisamment d’echanges d’argumentation entrainant des taux de reponse eleves, malgre les longs temps de reponse, qui a leur tour ont favorise la croissance du volume des discussions.
Metabolic enzymes in gene control

textabstractCellular compartments are believed to serve functional separation within the cell and allow it to perform multiple metabolic processes at the same time. Processes are divided between compartments with respect to the physiological requirements for a certain process. Thus, regulatory processes involving chromatin organization and control of gene activity are performed in the nucleus while metabolic processes are believed to be performed in the aqueous cytoplasm and cytoplasmic organelles. Numerous reports demonstrate that transcriptional modulation has a strong impact on metabolism, as expression levels of metabolic enzymes are limited by signaling pathways and the transcriptional machinery (Blanchet et al., 2011; Desvergne et al., 2006; Dufour et al., 2011). On the other hand, there should be mechanisms allowing feedback control from metabolism to gene expression that would tune the transcriptional program of the cell in accordance with its physiological needs (McKnight, 2010; Ray, 2010). Essentially, metabolic flux, including metabolic enzymes, small metabolites, nutrients and redox state, should impose reciprocal control upon nuclear events. However, there is little knowledge on mechanisms that allow such regulation. In recent years, several groups addressed this question and discovered that concentrations of intermediate metabolites indeed affect gene control (Shi, 2004). In all cases, metabolic compounds such as NADH, Acetyl-CoA and poly-ADP ribose bind to chromatin and change gene activity. Potentially many more metabolites should touch upon the gene expression machinery. These “metabolic” regulatory complexes might, in turn, affect expression of the transcriptional regulators of metabolism and close the feedback loop.
Animal Studies Repository 10-2012 A ‘ ‘ Practical ’ ’ Ethic for Animals

Drawing on the features of ‘‘practical philosophy’’ described by Toulmin (1990), a ‘‘practical’’ ethic for animals would be rooted in knowledge of how people affect animals, and would provide guidance on the diverse ethical concerns that arise. Human activities affect animals in four broad ways: (1) keeping animals, for example, on farms and as companions, (2) causing intentional harm to animals, for example through slaughter and hunting, (3) causing direct but unintended harm to animals, for example by cropping practices and vehicle collisions, and (4) harming animals indirectly by disturbing lifesustaining processes and balances of nature, for example by habitat destruction and climate change. The four types of activities raise different ethical concerns including suffering, injury, deprivation, and death (of individuals), decline of populations, disruption of ecological systems containing animals, and extinction of species. They also vary in features relevant to moral evaluation and decision-making; these include the number of animals affected, the duration of the effects, the likelihood of irreversible effects, and the degree to which the effects can be controlled. In some cases human actions can also provide benefits to animals such as shelter and health care. Four mid-level principles are proposed to make a plausible fit to the features of the four types of human activities and to address the major ethical concerns that arise. The principles are: (1) to provide good lives for the animals in our care, (2) to treat suffering with compassion, (3) to be mindful of unseen harm, and (4) to protect the life-sustaining processes and balances of nature. This ‘‘practical’’ approach arguably makes a better fit to the complex, real-life problems of animal ethics than the single foundational principles that have dominated much recent animal ethics philosophy.
Towards Secure & Green Advanced Metering Infrastructure (AMI)

This paper deals with the design issues of a secure and green Advanced Metering Infrastructure (AMI). The first part of the paper suggests enhancing the reliability of AMI system using wireless ad hoc Network technology. The suggested Advanced Metering Infrastructure consists of various types of wireless nodes we called Green Wireless Router (GWR). Here, we propose that GWRs can harvest the energy needed for its work from the surrounding environment, especially solar energy. Such suggestion permits to install GWRs in any place without considering the power supply availability and hence, extensive area is covered by the AMI. The different network traffic patterns generated from running a customized AMI simulation model were used in an experimental network based mainly on UBICOM IP2022 network processor platform (as the implementation of the intended GWR)with the aim of measuring its power consumption under different realistic circumstances. In order to decrease the power consumption of the suggested GWR and to extend the life time of the batteries, two power management schemes we called Controlled Duty Cycling (CDC) and Event Driven Duty Cycling were suggested and implemented. The second part of the paper suggests a GWR security model to protect it against different internal and external threats. The suggested GWR security model must respond to many objectives, it should ensure that the administrative information exchanged is correct and undiscoverable (information authenticity and privacy), the source is who he claims to be (message integrity and source authentication) and the system is robust and available (using Cooperative Intrusion Detection System).
