Collaborative Filtering and Artificial Neural Network Based Recommendation System for Advanced Applications

Author: Bharadwaja Krishnadev

To make recommendation on items from the user for historical user rating several intelligent systems are using. The most common method is Recommendation systems. The main areas which play major roles are social networking, digital marketing, online shopping and E-commerce. Recommender system consists of several techniques for recommendations. Here we used the well known approach named as Collaborative filtering (CF). There are two types of problems mainly available with collaborative filtering. They are complete cold start (CCS) problem and incomplete cold start (ICS) problem. The authors proposed three novel methods such as collaborative filtering, and artificial neural networks and at last support vector machine to resolve CCS as well ICS problems. Based on the specific deep neural network SADE we can be able to remove the characteristics of products. By using sequential active of users and product characteristics we have the capability to adapt the cold start product ratings with the applications of the state of the art CF model, time SVD++. The proposed system consists of Netflix rating dataset which is used to perform the baseline techniques for rating prediction of cold start items. Continue reading

Unravelling the Functions of Regulatory T Cells during Infection

Authors: Tania Rahman, Md Ferdous Seraj, Annelise Casellato

Accumulating evidences have suggested that Treg have an active role in the regulation of immunity to infection. Treg suppress not only autoimmune responses but also other immune responses for instance, during acute infections, against commensal microbes in inflammatory diseases or during chronic illness. Treg have been shown to limit exacerbated inflammation to avoid collateral tissue damage. Treg are also suggested to provide early protective responses in some viral infections as the permitting timely entry of effector cells in infected tissue. Furthermore, Treg have been shown to contribute to form memory pool after resolution of infection. In this review, we survey and analysis our current knowledge and relative dynamics of Treg in a wide range of infection settings and elaborate the examples in which these cells are of critical importance in conferring tolerance, suppressing pathogenesis, inducing protection and optimizing immunity to eliminate infection.

Molecular Genetics of Salt Tolerance in Tomato F2 Segregating Population with the Aid of RAPD Markers

Authors: Vincent Ezin, Tatsiana Dasenka, Pelagie Bidossessi Agbobatinkpo,
Adam Ahanchede, Avtar Krishan Handa

Salt tolerance of segregating progenies of a cross between a domesticated salt sensitive tomato cultivar (CA4) and a natural salt-tolerant wild-type tomato species (LA1606) was characterized. The F1 plants from this cross were selfed and 120 F2 segregating progenies from the resulting population along with parental CA4 and LA1606 plants were evaluated for salt tolerance. These plants were irrigated everyday with 185 mM NaCl for 82 days and quantitative traits were quantified including number of flowers, fruit number, fruit weight, fruit length, fruit width, fruit set percentage, and total yield. The two parental lines were evaluated for the presence of 27 seven independent RAPD markers and 7 markers were found to be polymorphic for the two genotypes. Bulk Segregant (BSA) analyses consisting of pooling 10 “most tolerant” and 10 “most sensitive” F2 segregating plants showed association of two RAPD polymorphic markers with higher salt tolerance. Two DNA markers that exhibit co-segregation with salt tolerance were identified and characterized. RAPD marker OPX-17 and MRTOMR-022 exhibited 2 positive molecule markers (polymorphism) which were found only in the resistant parent (LA1606) and resistant F2 bulk.

Emulsification Properties of Lactose Fatty Acid Esters

Authors: Seung-Min Lee, Ashwini Wagh, Guneev Sandhu, Marie K. Walsh

Sugar fatty acid esters (SFAE) are a class of synthetic emulsifiers used in the food, pharmaceutical, and personal care industries. The influence of the fatty acid chain length on the emulsification properties of lactose fatty acid esters (LFAE) including lactose monooctanoate (LMO), lactose monodecanoate (LMD), lactose monolaurate (LML) and lactose monomyristate (LMM) was investigated in this study. The stability of the emulsions as well as the oil droplet size distribution in 20% soybean oil-in-water emulsions was measured at 0.1%, 0.25% and 0.5% of LFAE concentrations. In order of LFAE with the strongest emulsion stabilization characteristics were LML, LMD, LMO and LMM. Oil droplet distributions resulted in the same trend, with LML and LMD maintaining the smallest droplet sizes and thus the most stable emulsion. The hydrophilic-lipophilic balance (HLB) and critical micelle concentrations were determined for each LFAE. An increase in HLB value was seen with an increased CMC value for each LFAE, showing the strength of the linear relationship between these two measured values. Additionally, there was a decrease in HLB and CMC values with a decrease in the fatty acid chain length of each LFAE. This research showed that LML and LMD formed more stable emulsions, even with HLB and CMC values higher than those of LMM suggesting HLB and CMC values alone do not predict emulsifier effectiveness.

Spillover Effects of Budgetary Policies in Monetary Union: The Case of WAEMU

Authors: Chérif Sidy Kane, Ismaila Sanghare

With the help of a vector model for dynamic panel error correction (PVEC), this article examines the extent to which a country’s policy shocks spread to the economic activity of other countries in the West African Economic and Monetary Union (WAEMU). The results of one part, the emergence of externalities that cause asymmetric shocks and another part, the public expenditure shocks induce greater spillover effects on economic growth than public revenue shocks. Both results imply the structural heterogeneity of economies, leading to an uneven distribution of the benefits and costs of a common monetary policy. Therefore, corrective measures can be applied, through a real policy mix, which can reduce the risks of instability related to budgetary externalities.

Measuring Urban Sprawl Indices at Traffic Analysis Zone (TAZ) Level

Authors: Tahmina Khan, Michael Anderson

High rates of land use change causing unsustainable development have attracted the attention of policy and planning and raised the need to understand the factors behind it. Sprawl occurs because of the residents’ preference to live in suburbs, low-cost auto travel, technological innovations, the aspiration for urbanized-automobile dependent lifestyle, the disappearance of rural agricultural land, and spatial fragmentation. Thus, it induces sustainability challenges and leads to excessive commuting and congestion. There is a greater necessity to quantify urban sprawl at Traffic Analysis Zone level so that transportation and land use planners can identify potential sprawling TAZ and can promote/develop sustainable strategies for future land use planning. In this study, sprawling indices at TAZ level were derived with and without incorporating centering effect and compared the scores of sprawling TAZs in 2010 to the sprawling TAZs for 2000. The main goal was to propose a methodology for determining potential sprawling TAZs and to identify locations responsible for sprawl in a case study city. The results can be a substantial input in planning and decision-making process.

CCS Membrane Development at CIUDEN’s Technology Development Centre for CO2 Capture

Author: Jose A. Gutierrez Bravo

CO2 concentration to the atmosphere has risen faster than ever in the last century. This is highly due to fossil fuel combustion which is the major anthropogenic CO2 source. Membrane technology is an important alternative for reliability, flexibility and economically competitiveness for Carbon Capture and Storage (CCS) processes. The use of membranes has applicability to CCS technologies mainly for CO2, O2 or H2 separation, although most of the membrane studies for CO2/O2 production have been carried out at laboratory scale and will require a step further for commercial scale. This paper will present current membranes R & D needs when applied to CCS systems and CIUDEN capabilities for membrane technological development and testing under real conditions. It covers from O2 separation membrane integration in the process, and applied to the oxy-combustion CO2 capture, to post-combustion technologies for membrane CO2 separation, tested under real conditions or H2 production catalytic-membranes through gasification. At CIUDEN CCS facility important membrane evaluations can be carried out for the module integration, testing of materials performance and behavior under real conditions.

Indication and Timing of Surgery Are Essential in Stabilization of the Chest Wall in Flail Chest Trauma Patients

Authors: Ali Imad El-Akkawi, Frank Vincenzo de Paoli, Morten Bendixen,
Thomas Decker Christensen

Flail chest occur after blunt trauma to the thorax. Most often treatment of flail chest is conservative with analgesia and respiratory support, if needed. New plate systems and surgical approaches have improved outcomes after surgery. Surgical treatment of flail chest is associated with a reduced risk of severe pneumonia, shorter time with mechanical ventilation and a reduced length of stay in the Intensive Care Unit (ICU) compared to conservative treatment. However, currently approximately 1% of patients with flail chest undergo surgery. We are presenting two cases of flail chest treated surgically by fixating the most dislocated posterior fractures. One patient avoided mechanical ventilation, and the other patient was quickly weaned from respirator after surgery. We found that surgical stabilization of posterior fractures in patients with flail chest is a safe method with a high possibility of positive outcomes for the patients. Surgical stabilization of flail chest is indicated in patients with consistent pain (case 1) and increased risk of pneumonia, respiratory failure or prolonged mechanical ventilation (case 2). Furthermore, it was possible to achieve stable thorax wall by only fixating the most dislocated posterior fractures in the flail segment.

Investigating Economic Growth, Trade Issues and Future Energy Strategies for Central Asian Countries

Authors: Olimjon Djumabaev, Tatsuo Oyama

We examine the economic growth, energy development policies and strategies for the CAC from various perspectives. We apply statistical data analysis techniques and mathematical modelling methodologies focusing upon regression model analysis in order to deal with the economic and energy related data during the period 1990-2014, and to investigate the relationship among economic growth, energy production, and the trade of energy resources in order to find future desirable policies and strategies for the CAC. Findings show that energy production growth would bring statistically significant positive impact on GDP growth in fossil-fuel rich Kazakhstan, Uzbekistan, and Turkmenistan while we also find negative impact of GDP growth on the trade balance of the CAC except for Turkmenistan. Another finding follows that the foreign direct investment has a significant influence on the trade balance in the cases of Uzbekistan and Turkmenistan, which institute import substitution policies right from their initial years of independence. Based on these quantitative investigations on economy, energy, and trades we propose future energy strategies for the CAC, stressing the importance of diversification of economies.

Authors: U. A. Birnin-Yauri, M. K. Musa, S. M. Alhaji

The study was conducted to determine the concentrations of heavy metals (Cu, Zn, Co, Mn, Fe, Cr, Cd and Pb) in the liver, kidney and flesh of Cattle, Sheep and Goats from Anka and Bukkuyum Local Government areas of Zamfara State Nigeria. The levels of heavy metals in the liver, kidney and flesh of beef, mutton and caprine ranged from 56 to 549 μg·g-1 for Zn; 109 to 576 μg·g-1 for Fe; 0.0 to 4.0 μg·g-1 for Pb; 2.52 to 13.25 μg·g-1 for Mn; 0.00 to 19.64 μg·g-1 for Cr; 0.00 to 0.25 μg·g-1 for Cd; 0.00 to 2.71 μg·g-1 for Co and 3.59 to 538 μg·g-1 for Cu. The concentration of Cr, Pb and Mn in the kidneys and livers of the samples were observed to be higher than the maximum allowable level. Similarly, the exception of Cr in the liver of sheep and goat from Anka and liver of sheep from Bukkuyum, Pb in some liver and kidney samples and Mn in some liver, kidney samples and flesh of cattle from Anka were found to be polluted and hence unsafe for consumption.
