Joint Source-Channel Coding for Wireless Image Transmission based OFDM-IDMA Systems

The source and channel coding for wireless data transmission can reduce distortion, complexity and delay in multimedia services. In this paper, a joint sourcechannel coding is proposed for orthogonal frequency division multiplexing interleave division multiple access (OFDM-IDMA) systems to transmit the compressed images over noisy channels. OFDM-IDMA combines advantages of both OFDM and IDMA, where OFDM removes inter symbol interference (ISI) problems and IDMA removes multiple access interference (MAI). Convolutional coding is used as a channel coding, while the hybrid compression method is used as a source coding scheme. The hybrid compression scheme is based on wavelet transform, bit plane slicing, polynomial approximation model and absolute moment block truncation. The wavelet transform is exploited to decompose the image into approximation and detail sub bands, while the polynomial model is used to code the approximation image band. Simulation results show that the proposed system reduces distortion efficiently (i.e., preserving image quality) and achieves a simple method for image multiuser transmission over wireless channels.

Size Effects: The Relation to the Percentage of Atoms That Participate in the Deformation of ZrCu Metallic Glass

Molecular dynamics simulations indicate that with the model diameter gradually decreasing the deformation mode of ZrCu metallic glass evolves from highly localized shear band formation to homogeneous deformation with obvious transition in nm. Through the statistic of atoms that sustain shear strain larger than 8% in the models with 8% strain along -direction, we found that the main reason for the uniform deformation that occurs in the smallest size model is that there are 61% atoms involved in the deformation, which significantly decrease the strain assigned to individual atoms, avoiding large atomic rearrangement and making those atoms evenly distributed in the model matrix.
Draught and Soil Disturbance of Model Tillage Tines Under Varying Soil Parameters

Soil bin investigations were carried out to study the influence of some soil parameters namely: moisture content and cone index, on draught force and soil disturbance of model tillage tools. The tools were tines in the groups of very narrow tines, narrow tines and wide tines. The soil under study was a sandy clay loam. It was observed that draught increased at a decreasing rate as the soil moisture content increased from 11 to 22.5% (db). Polynomial regression models best described the relationships with high R2 (coefficient of determination) values. Soil disturbance parameters: ridge-to-ridge distance, width of crescent or width of furrow at the surface, total disturbed width, height of ridge, and furrow depth were determined. Tine draught increased at an increasing rate as compaction increased for a cone index in the range of 150 to 800 kPa with polynomial regression equations best describing the relationships. The models generated in this study were suitable for predictive purposes.
Gas exchange in rivers and estuaries: Choosing a gas transfer velocity

We are writing this comment to call attention to large uncertainties in the estimates of CO2 flux from rivers and estuaries, a topic that has been receiving considerable attention recently (Raymond et al. 1997, 2000; Cai and Wang 1998; Frankignoulle et al. 1998). It is our view that there are too few direct measurements of the physical component of gas exchange (e.g., the gas transfer velocity, piston velocity, gas exchange coefficient, or k) for rivers and estuaries. While studies in streams, lakes, and marine systems have progressed to the point where the gas transfer velocity can be partially predicted from physical forcing functions (O’Connor and Dobbins 1958; Cole and Caraco 1998; Wanninkhof and McGillis 1999), this is not yet the case for estuaries and rivers. A comparison of gas transfer velocity measurements in estuaries and rivers reveals a general lack of agreement among studies and physically-based predictive models. Until we have a better understanding of the magnitude and causes of variation in estuarine gas transfer velocity estimates, it will be difficult to use gas exchange in rivers or estuaries to accurately mass-balance gases of interest. The exchange of CO2 between an aquatic ecosystem and the overlying atmosphere is an area of intense interest for several reasons: aquatic systems can be significant CO2 sources or sinks on a global or regional scale (Kling et al. 1991; Quay et al. 1992; Sarmiento and Sundquist 1992; Cole et al. 1994); the magnitude and direction of an ecosystems CO2 flux can provide important clues about metabolism in a given system (Depetris and Kempe 1993; Gattuso et al. 1993; Hamilton et al. 1995;
End of a modern geological myth: there are no rudists in Brazil! Paleobiogeographic implications

Out of the few records of rudists from the Cretaceous strata of the South Atlantic coastal basins only two refer to Brazilian localities. However, petrographic analyses demonstrate that these shells should be assigned to Ostreids or to Pycnodontids rather than to Rudistids. More specifically, the domain considered herein, north of the Rio Grande Rise - Walvis Ridge barrier, was part of the warm-water "tropical" realm, but it was not part of the Mesogean domain because both Rudistids and Orbitolinas are missing. In addition, the scarcity of corals leads us to ascribe the taphonomic assemblage to the Chloralgal facies. Neither generalized hypersalinity or extreme sea-water temperatures seem to account for these biotic peculiarities. Instead, our alternative hypothesis favors the driving role played by oceanic circulation in the dispersal of the benthic organisms.
OPTIMISATION OF THICKNESS OF FIBRE REINFORCED POLYMER SHEETS FOR STRENGTHENING REINFORCED CONCRETE BEAMS WITH FLEXURAL DEFICIENCY

The use of Fiber Reinforced Polymer (FRP) is becoming a widely accepted solution for repairing and strengthening of deteriorated reinforced concrete members, to restore their load carrying capacities. One of the major concerns in the use of FRP is its cost. This therefore calls for the use of efficient and cost effective design approach. Design efficiency in terms of cost can be achieved through optimisation. In the present paper, Generalized Reduced Gradient (GRG) optimisation technique was employed to optimize the strengthening cost of a simply supported reinforced concrete beam strengthened with Fibre Reinforced Polymer (FRP). Optimum design charts for the considered problem were presented. The results showed that considerable savings in thickness can be achieved using FRP of high modulus of elasticity. For example at very high capacity reduction say 70% (k c = 0.3), the required FRP thicknesses for FRP with elastic moduli of 25GPa, 50GPa, 75GPa, 100GPa, 125GPa and 150GPa are respectively equal to 2.5mm, 1.75mm, 0.75mm, 0.6mm, 0.5mm and 0.4mm. http://dx.doi. org/10.4314/njt.v36i1. 7
INSECT SUCCESSION ON DOG (CANIS LUPUS FAMILIARIS L.) CARCASSES IN SAMSUN PROVINCE, TURKEY

This field study was carried out succession of insect in the Taflan at Samsun province (Turkey) in the period from June 2009 to May 2010 by using dog (Canis lupus familiaris L.) carcasses as a human model. Eight dog carcasses (20-35 kg) were employed in this field in four seasons. The aim of this study was to determine the forensically significant insect succession and seasonal distribution in Samsun province. In our study five decomposition stages were observed (fresh, bloated, active decay, advanced decay, dry). The carcasses decomposed more rapidly in summer and autumn but carcasses decayed slowly in winter and spring. Carcasses attracted 25 species of insect in our study. During this period, a lot of insects belonging to the following orders and families were collected: Diptera: Calliphoridae, Sarcophagidae; Coloeptera: Staphylinidae, Histeridae, Dermesitidae, Cleridae, Nitidulidae, Silphidae. In spring and autumn carcasses attracted a more different community of insects than winter-placed carrion. No Coloepter species were collected in the winter. Insect fauna and its seasonal differences in Samsun on dog carcasses were reported for the first time in this study, strengthening the need of further experiments in different regions of Turkey in order to forensic practice.
THE COMPARATIVE ROLE OF ASCORBATE AND CHELATORS IN REVERSING OXIDATIVE STRESS, HEPATIC AND RENAL DYSFUNCTION IN SUB-ACUTE LEAD POISONING

Lead has been implicated in the induction of reactive species production, leading to organ dysfunctions. The ameliorative roles of ascorbate and chelators in acute lead poisoning were comparatively studied in thirty-five male Wistar rats (150-200g), segregated into 5 groups (n=7/Group): group 1(administered normal saline),a¤? groups 2-5 were orally exposed to 75mg/kg body weight lead acetate (PbAc) daily for 14 days. Pre-therapy blood samples were collected to ascertain blood lead level (BLL) and catalase activity 24hours after the last PbAc exposure. Groups 3, 4, and 5 were then treated with 30mg/kg body weight D-penicillamine; 30mg/kg body weight succimer; and 500mg/kg body weight ascorbate respectively for 10 days, followed by the assay for indices of oxidative stress, hepatic and renal dysfunctions. a¤? Results obtained showed significantly elevated BLL in the four groups exposed to PbAc. which were significantly reversed about 2 folds in groups 3-5 after therapeutic interventions. Pre-therapy blood catalase activity of the PbAc treated groups was significantly (p<0.05) reduced by 39% when compared with the control group, however ascorbate significantly (p<0.05) increased catalase activity by 2 folds above the control; decreased plasma activities of alanine transaminase and aspartate transaminase, blood urea nitrogen and creatinine among the groups administered therapeutics. These findings indicate that ascorbate is more effective a¤?

Carotene content of coriander leaves (Coriandrum sativum), Amaranth, Red (Amaranthus Sp, Green garlic (Allium sativum) and Mogri (Raphanus caudatus) and its products

Abstract Food based approach is a more practical and sustainable approach to combat micronutrient deficiencies including vitamin A deficiency in India. However several gaps of knowledge with respect to the stability of β- carotene from foods and therefore its bioavailability exist. The present study aimed to assess the total and beta- carotene content of 4 vegetables (Coriandum sativum), Amaranth, Red (Amaranthus sp); Green garlic (Allium Sativum) and Mogri (Raphanus caudatus); and study the stability of beta carotene using minimal processing and addition of weak acids from foods, and product development using of coriander leaves. Results indicate that among the four vegetables, beta-carotene content of coriander was highest (2921.79μg/100g) and lowest for mogri (425.15μg/100g). When coriander leaves were macerated alone in an electric mixer grinder and with green chilies, lemon or both, retention of beta carotene was 72.3%, 149.81%, 98.2%, and 182% resp. indicating the enhancing effects of green chillies and lemon juice of β- carotene retention. The fresh coriander leaves when incorporated into a recipe retained 75.47% of total carotene and 74.185 of β- carotene and was found to be highly acceptable using the composite score and hedonic test. The study indicates that minimal processing and usage of green chillies and lime in carotene rich foods enhance its retention. Efforts should be directed towards development of acceptable recipes incorporating green leafy vegetables and thereby resulting in an increased intake of β-carotene rich indigenous foods.
Dynamics of metal‐silicate separation in a terrestrial magma ocean

In a terrestrial magma ocean, the metal‐silicate separation involved small metal droplets. Our goal is to better understand the dynamics of the metal droplet scenario. The mechanism of sedimentation in a vigorously convecting and strongly rotating magma ocean may differ significantly from settling droplets in a still fluid. In order to systematically study the parameter dependence on the style of motion we utilize two‐dimensional and three‐dimensional numerical convection models combined with a tracer‐based sedimentation method. We investigate the characteristic flow patterns resulting from the competing effects of convection and droplet settling and find three styles of motion: a temperature‐dominated style where most droplets remain suspended, a droplet‐dominated style where the droplets separate from the fluid, and a style of repetitive motion. We find that the droplet‐dominated style is relevant to the magma ocean. In this scenario the droplets settle and form a dense bottom layer. One of the key findings of this work is that the formation of the dense bottom layer, and therefore the separation of metal droplets from the liquid silicate, occurs on a characteristic timescale, which is identical with the Stokes' settling time. Finally, we study the chemical interaction of settling metal droplets and liquid silicate and discuss how accurately a simple parameterized model can describe the chemical equilibration in the metal‐rain scenario of a terrestrial magma ocean. We find agreement between the parameterized model and our two‐dimensional model. Our simulations, which include thermal convection into the metal‐rain model, confirm the fundamental observation that metal droplets are not permanently suspended in the convecting silicate melt, but that they sink and rapidly form a dense layer at the base of the magma ocean.
Modeling Properties for the Design of Branched Sheet Metal Products

This paper presents an approach to designing multi-chambered pro le structures made by a new manufacturing process called linear ow splitting using an algorithm based approach. The basis for this procedure is a systematic view of product properties and the separation of its internal and external properties. The link between product properties must be derived by design knowledge such as physical models or guidelines. This specific knowledge enables one to decide which internal properties, as optimization parameters, need to be adjusted in order to meet desired external properties. This procedure leads to mathematical problems that are difficult to solve, presenting a challenge for research. This approach is demonstrated with an example of a development assignment seeking a topology of a pro le structure consisting of several chambers

Mobile applications (apps) developers often reuse code from existing libraries and frameworks in order to reduce development costs. However, these libraries and frameworks are governed by licenses to which developers must comply. A license governs the way in which a library or chunk of code can be reused, modified or redistributed. It can be seen as a list of rules that developers must respect before using the component. A failure to comply with a license is likely to result in penalties and fines. In this thesis, we propose our approach for license identification in open source applications. By applying this approach, we conduct a case study to identify licenses in 857 mobile apps from the F-droid market with the aim to understand the types of licenses that are most used by developers and how these licenses evolve overtime. We conduct our study both at project level and file level. We also investigates licenses violations and the evolution of these violations overtime; we compare licenses declared at the project level, file level and those of the libraries used by a project to seek for licenses that are incompatible and used in the same project. Results show that most used Licenses are GPL and Apache licenses both at the project level and file level. In many cases we noticed that developers didn’t pay too much attention to license their source code. For 3,250 apps releases out of 8,938 releases, the apps were distributed without licenses information. Regarding license evolution, we noticed that the probability for a project to stay under the same license is very high (95% in average) and in case of change, changes are generally toward more permissive licenses. At the file level, we noticed that developers tend to delay their decision about license selection, also in 15% of license changes, developers removed licensed information. We identified 15 projects out of 857 projects, with a license violation; 7 projects had violations in their final release. To solve license violations, developers either changed the license of some of the apps’ files or removed the contentious files from the apps. It took in average 19 releases to solve a license violation. These findings suggest that developers of mobile apps may be having some difficulties in understanding the legal constraint of licenses’ terms or it may be that the lack of consistency and standardization in license declarations fosters confusion among developers. Our license detection approach can be used by developers to track license violations in their projects.
Design of a Sensor to Detect Fruit Freshness

Fruits and vegetables constitute a significant part of human diet habit for decades. In modern age with the increased disease variant, people became more curious about the natural and organic nutrition. This current of thought has brought some problems with it which are mostly related to freshness. As fruits and vegetables are a good source of food for us they are also good hosts for microorganisms like bacteria and fungi too. Foods contaminated by microorganisms could cause serious health problems in addition to that, decayed fruits and vegetables create several problems during imports and exports, during their storage for food related companies and markets. To find a solution to these problems a freshness sensor is developed which works with the principle of measurement of ion concentration change occurred in fruits and vegetables. Performed tests show that according to ion concentration change we could determine the freshness of fruits and vegetables. This method doesni¯t need any chemical pretreatment and it is not a type of storage method like in literature. This sensor can be used easily during grocery shopping by consumers, by import and export quality controllers or by any food related factory since it could give an average time of usage and this sensor could prove even frozen foods' freshness.

AMPLIFICATION, CLONING AND EXPRESSION OF BRUCELLA MELITENSIS BP26 GENE (OMP28) ISOLATED FROM MARKAZI PROVINCE (IRAN) AND PURIFICATION OF BP26 PROTEIN

Brucellosis is a debilitative disease that imposes costs on both economy and society. It is shown that although the vaccine can prevent abortion, it does not provide complete protection against infection. In Iran, Brucella melitensis is a common causative agent for brucellosis and BP26 protein of this bacterium having a good antigenesity and an important vaccine candidate. In this study B. melitensis bp26 gene was cloned first in to PTZ57R/T vector and accessed on the PET28a vector and sequenced. Recombinant vector transformed and expressed in to E. coli BL21 (DE3) and then recombinant protein was purified with Ni-NTA column of chromatography against His tag. Obtained rOmp28 could be used as a research experimental tool to find its potential as a detection kit and vaccine candidate.
Spoken discourse in Alzheimer' disease: a review

In its typical form, Alzheimer’s disease (AD) manifests with early impairment in episodic memory. Evidence suggests that language deficits also occur early on in the disease process, and can be detected at the preclinical stage, suggesting that language could constitute an important diagnostic marker for disease. Additionally, a number of variant clinical presentations of AD are recognised, due to an atypical distribution of pathology at onset, including a minority of patients presenting with a slowly progressive language impairment. We review language performance in typical and atypical presentations of AD, and describe a series of recent, novel findings examining the language phenotype of typical AD.
Processing of polymer matrix nanocomposites with carbon nanotubes

Carbon nanotubes (CNTs) are crystalline carbon structures with extraordinary mechanical, chemical and electrical properties. These unique properties make CNTs potentially valuable in a wide range of end-use applications. As a consequence, we discussed background material on the chemistry and properties of CNTs that will be familiar to nanotube researchers and material on carbon nanotube based nanocomposites. It is the aim of this work to consider the approaches to chemical functionalization of CNT and to account for the advances that have been produced so far.
INFLUENCE OF STRATEGIC RESPONSES ON THE CHANGES IN THE INTERNAL PERFORMANCE AMONG PHARMACEUTICAL FIRMS IN KISII COUNTY, KENYA

Pharmaceutical firms are challenged with high compensation demanded by qualified workers. Though it is clear that qualified personnel is required for good performance in the health sector, it is not clear what strategic responses are used by pharmaceutical firms to improve the performance in offering their services. Specific research objectives in this study were: to assess the relationship between strategic responses and internal performance in pharmaceutical firms, to find out the level to which setting of targets influence internal performance of pharmaceutical firms in Kisii County, to establish the level to which working environment influences internal performance of pharmaceutical firms in Kisii County and to find out the level to which amount of salary influence internal performance of pharmaceutical firms in Kisii County. Target population comprised of the respondents from 42 pharmaceutical firms operating in Kisii County. A census method was used and the data was analyzed using SPSS. The study found out that most team building workshops were organized once a year. Most pharmaceutical firms provide medical cover to their employees. Most employees take annual leave and it does not have any effect on internal performance of pharmaceutical firms. And that the internal performance of pharmaceutical firms is influenced with employees’ salary per month. Results of this study therefore will help managers of pharmaceutical firms as they understood how different strategic responses influence their subordinates’ performance and decide which strategic responses to use to effectively manage the performance in a bid to improve productivity of the subordinates.
