Published: November 2015

An experiment was conducted at the Agronomy Field of Sher-e-Bangla Agricultural University, Dhaka-1207 during the period from November 2011 to March 2012 to evaluate the performance of prilled urea and urea super granules (USG) on the growth and yield of wheat varieties. The experiment comprised of four wheat varieties viz., BARI Gom 21, BARI Gom 24, BARI Gom 25 and BARI Gom 26, and five nitrogen (N) levels viz., control (no Nitrogen), 84 kg ha-1 N from USG, and 30, 50 and 70 kg N ha-1 from prilled urea i.e., 67, 112 and 155 kg urea ha-1. The experiment was laid out in a split-plot design with three replications where wheat varieties were placed in the main plot and nitrogenous fertilizers in sub-plots. Experimental results indicated that different varieties had the significant effect on plant height, number of tillers and dry weight plant-1, and number of grains spike-1, grain and straw yield, and harvest index. The variety BARI Gom 24 produced the highest grain yield (2.49 t ha-1) that mainly attributed by the maximum number of spikes plant-1, number of grains spike-1 and 1000-grain weight. Among the different nitrogenous fertilizers 84 kg N ha-1 from USG (1.8 g) gave the highest grain yield (2.69 t ha-1) due to the maximum number of spikes plant-1, maximum number of grains spike-1 and 1000-grain weight. The variety BARI Gom 24 produced the highest grain yield (2.80 t ha-1) with 80 kg N ha-1 from USG application.Bangladesh Agron. J. 2015, 18(1): 37-48

Published: November 2015

An experiment was carried out at research field of Bangladesh Rice Research Institute, Gazipur to evaluate the performance of tidal local aman rice as influenced by urea super granule (USG) at non-tidal condition. Four tidal local aman varieties such as Sadamota, Razashail, Kutiagoni and Kalagura were used as planting materials. Nitrogen was applied as USG (1.8g) at 10 days after transplanting (DAT), 25 DAT, before panicle initiation (BPI) stage (date of PI stage of these 4 varieties were identified from previous experience) and no nitrogen (control). The experiment was laid out in a split-plot design where varieties in main plot and USG in sub-plot with three replications. Varietals response was significant on plant height, effective tillers hill-1, grains panicle-1 and grain yield. All the yield and yield components were influenced significantly by the time of USG application. Higher dry matter was produced by all the varieties when USG was applied at early growth stage (10 to 25 DAT) but crop lodges at milking stage due to more vegetative growth resulting increases sterility, decreases grain fertility and yield. On the other hand, when USG was applied at BPI stage grain fertility and yield were increased. The highest grain yield (3.51 t ha-1) was recorded from Kalagura when USG applied before panicle initiation stage. So, application of USG at BPI stage in local aman rice in non-tidal condition increased yield resulting higher gross and net return in all varieties.Bangladesh Agron. J. 2015, 18(1): 71-80
Synthesis, antimalarial activity evaluation and molecular docking studies of some novel dispiro-1,2,4,5-tetraoxanes
Authors: Kumawat Mukesh Kumar , Chetia Dipak
Published: November 2015

Seven novel dispiro-1,2,4,5-tetraoxane derivatives were synthesized and characterized by a number of analytical and spectroscopic techniques. The molecules were subsequently screened for in vitro antimalarial activity against chloroquine resistant strain of Plasmodium falciparum (RKL-9). At antimalarial activity screening, two compounds, namely 5d (MIC = 15.6 µg/mL or 64.5 µM) and 5f (MIC = 15.6 µg/mL or 54.6 µM) were found to be about 1.5 times more potent against chloroquine resistant strain-RKL-9 compared to chloroquine (MIC = 25.0 µg/mL or 78.3 µM). Molecular docking studies of potent ligands were also performed in cysteine protease binding pocket residues of falcipain-2 as a target protein.

Published: November 2015

An investigation was carried out for the production of biogas from dry fallen leaves. The sample was collected from BCSIR campus of Dhaka in winter. The substrate was mixed leaves mainly mahogany (75%), eucalyptus (10 %) and rain tree (15 %) leaves. The study was carried out by whole leaves and crushed leaves directly followed by aerobic pretreatment at 8% total solid (TS) concentration. The raw materials were fed into two liter capacity glass bottle bio digester on batch basis for 60 days at ambient temperature. Different proportion of substrate and cow dung were mixed to get the optimum mix for maximum yield of biogas. The biogas reactor containing 6% crushed and pretreated leaves mixed with 2% cow dung (on 8% TS basis) gave maximum (0.199 l/g) biogas yield. The biogas yield from leaves without pretreatment was found to be too low (0.0106 l/g) for 8%. The COD reduction, VS reduction and methane composition of two biogas reactors have been determined where biogas yield were relatively higher. The maximum methane content of the biogas was found to be about 69.3%.Bangladesh J. Sci. Ind. Res. 50(3), 163-168, 2015

Published: November 2015

This experiment was carried out to analyze the effects of CCB (chromate-copper-boron) preservative treatment on physical and mechanical properties of Albizia richardiana wood using dipping method. Retention of preservative was maximum at 8% concentration of the preservatives. Based on the retention at this concentration, the physical and mechanical properties of the treated wood were examined. The density of untreated A. richardiana wood was 521 kg/m3. It changed to 542 kg/m3 on treatment. This increase in density by 2.30% for treated wood was significant. On the other hand, modulus of rupture (MOR) increased significantly from 93 to 107 N/mm2 on treatment of the wood. The modulus of elasticity (MOE) increased from 3205 to 4861 N/mm2. Physical and mechanical properties of the wood improved by treating with CCB preservative.Bangladesh J. Sci. Ind. Res. 50(3), 189-192, 2015

Published: November 2015

Sesame is a well known oil seed crop in arid and semiarid region of Pakistan and its productivity is affected due to sensitiveness to water logging in the root zones. The experiment was conducted at research area of Agronomic Research Station, Bahawalpur during the year 2010 and 2011. The crop was sown by three different planting techniques i.e. flat sowing with 45cm apart rows, ridge sowing with 45cm apart, bed sowing with 60/30 cm i.e. 60 cm wide beds with 30 cm furrow between the beds. The data revealed that maximum number of plants wilted in flat planting as compared to other methods of planting were taken in this experiment. It was also recorded that bed planting at 90cm apart beds gave maximum grain yield of 843 kg ha-1 followed by ridge planting (seed spreading by broadcast and with augmented furrows) with a grain yield of 811 kg ha-1. The lowest yield was obtained from conventional method of sowing which gave 349 kg ha-1 grain yield. Water logging stress in the root zone can successfully be avoided by planting sesame on beds or ridges under climatic conditions of Bahawalpur.Bangladesh J. Sci. Ind. Res. 50(3), 193-198, 2015

Authors: Biswas R , Das MC , Islam S , Haque MA , Shaikh AA
Published: November 2015

The electrochemical redox behavior of transition metal ion, Cu(II) at different pH in acetate buffer solution has been investigated using cyclic voltammetric method at glassy carbon electrode (GCE). Cyclic voltammograms of Cu(II) show two cathodic and an anodic peaks those remain identical at various pH. The cyclic voltammetric response of the metal ion has been observed in presence of proton pump inhibitors (PPIs) such as omeprazole, pantoprazole, esomeprazole and rabeprazole at various proportions of metal ion and PPIs. The nature of cyclic voltammograms of Cu(II) has been changed dramatically in presence of the PPIs due to the strong interaction between metal ion and PPIs. Almost similar interaction was noticed for all the PPIs. However, the maximum interaction was found at 1:2 molar ratio of Cu(II) and PPIs. The result could provide deep insight into the interaction between various metal ions and the PPIs that have been taken quite regularly in human bodyBangladesh J. Sci. Ind. Res. 50(3), 219-226, 2015

Summary: Antibodies are globulins which are produced in response to an antigenicstimulation. The antibody that activates complement leading to cell lysis is calledhemolysin antibody. Group O donors plasma may contain potent anti A or anti-B, capable of reacting with the red cells ofgroup A, B or AB recipent and sometimescause a severe transfusion reaction. The anitbodies may take the form of high titre agglutinins or hemolysins. Patients blood group A, B or AB receiving O blood groupwith a high titre IgG anti-A or anti-B reacting at 37°C may experience a moderatetransfusion reaction resulting jaundice and progressive anaemia. Immune anti-A and anti- B are sometimes responsible for transfusion reaction.Objective: To find out the haemolysintitre of O blood group female donor.Methods: This cross sectional study was done on 100 cases of O blood group female inchild bearing age and 100 adult male was selected as control, in transfusion medicine department, BSMMU from June 2008 to May 2009.

Theorising ageing and the question of a long life: eye openings
Authors: Biggs Simon
Published: November 2015

A life course perspective, drawing on historical and personal experiences, is used to identify eye-opening concepts that can be used to make sense of the world in terms of personal and social ageing, in the context of intergenerational relationships. Two issues have been identified that characterise a challenge to cultural adaptation: that of generations increasingly becoming approximately the same size as they move from demographic triangles to columns, and that of finding an age-specific purpose for a long life. An analysis of contemporary problems facing gerontology and social policy is given, drawing on the need for complementary life priorities and enhanced generational intelligence. Implications for work, generational rivalry and precarity are examined along with some conclusions on the role of eyeopening conceptual development.
Biochar for Soil Improvement: Evaluation of Biochar from Gasification and Slow Pyrolysis
Authors: Fryda Lydia , Visser Rianne
Published: November 2015

The growing need for food, energy and materials demands a resource efficient approach as the world’s population keeps increasing. Biochar is a valuable product that can be produced in combination with bio-energy in a cascading approach to make best use of available resources. In addition, there are resources that have not been used up to now, such as, e.g., many agro-residues that can become available. Most agro-residues are not suitable for high temperature energy conversion processes due to high alkali-content, which results in slagging and fouling in conventional energy generation systems. Using agro-residues in thermal processes, therefore, logically moves to lower temperatures in order to avoid operational problems. This provides an ideal situation for the combined energy and biochar production. In this work a slow pyrolysis process (an auger reactor) at 400 °C and 600 °C is used as well as two fluidized bed systems for low-temperature (600 °C–750 °C) gasification for the combined energy and biochar generation. Comparison of the two different processes focuses here on the biochar quality parameters (physical, chemical and surface properties), although energy generation and biochar quality are not independent parameters. A large number of feedstock were investigated on general char characteristics and in more detail the paper focuses on two main input streams (woody residues, greenhouse waste) in order to deduct relationships between char parameters for the same feedstock. It is clear that the process technology influences the main biochar properties such as elemental- and ash composition, specific surface area, pH, in addition to mass yield quality of the gas produced. Slow pyrolysis biochars have smaller specific surface areas (SA) and higher PAH than the gasification samples (although below international norms) but higher yields. Higher process temperatures and different gaseous conditions in gasification resulted in lower biochar yields but larger TSA, higher pH and ash contents and very low tar content (16-PAH). From the feedstock data looked at in more detail, a few trends could be deducted in the attempt to learn how to steer the biochar characteristics for specific uses.
Under Persistent Assault: Understanding the Factors that Deteriorate Human Skin and Clinical Efficacy of Topical Antioxidants in Treating Aging Skin
Authors: Farris Patricia , Krol Yevgeniy
Published: November 2015

Recent studies contend that the skin is subject to far more damage than just ultraviolet (UV) light, with infrared radiation and pollution now clearly demonstrated to degrade cutaneous tissue. While consumers continue to strive for new ways to augment the aesthetic appeal and improve the health of their skin, awareness regarding environmental insults and effective ways to protect the skin remains low. New advances in dermatologic science have exponentially increased the available information on the underlying mechanism of cutaneous damage and potential of topical antioxidants to treat aging skin. Combining antioxidants that can work through multiple pathways holds great potential for a cumulative and synergistic way to treat aging skin. Our goal is to provide a comprehensive review on environmental factors that damage human skin, discuss scientifically proven benefits of topical antioxidants, understand challenges of formulating and administering topical antioxidants, evaluate novel mechanisms of antioxidant activity, and suggest practical ways of integrating topical antioxidants with aesthetic procedures to complement clinical outcomes.
Reconstituted Keratin Biomaterial with Enhanced Ductility
Authors: Atri Halleh , Bidram Elham , Dunstan David
Published: November 2015

Nowadays the waste from protein fibres represents an important renewable source for a new generation of biomaterials and promising competitors for carbohydrate based biomaterials. Regenerated keratin biomaterials are biodegradable in vivo and in vitro, biocompatible, and support cell attachment and proliferation; however, their major drawback has been their weak mechanical properties such as ductility. The following study was conducted in an attempt to improve the ductility of reconstituted keratin films obtained from Australian merino wool fibres. Keratin was extracted from wool fibres according to an established protocol proposed by Yamauchi, and then dialyzed and desalted by multiple diafiltration wash cycles. The resulting keratin film was transparent, biodegradable, and, opposite to its predecessors, mechanically durable, possessing a Young modulus about 12.5 MPa with 35% extensibility. The polypeptide chains were found to rearrange themselves in the β-sheet state in this keratin film, which was shown to be semi-crystalline. This film, unlike its predecessors, did not support human cell proliferation. These properties of the diafiltered keratin film have led us to think that diafiltration resulted in producing a totally new keratin film, which is envisaged to find applications in various areas.

Published: November 2015

As a result of the wide distribution of herbal teas the data on nutritional characterisation, chemical profile and biological activity of these products are required. The decoctions of Gentiana algida, G. decumbens, G. macrophylla and G. triflora herb teas were nutritionally characterized with respect to their macronutrients, demonstrating the predominance of polysaccharides and low lipid content. Gentian decoctions were also submitted to a microcolumn RP-HPLC-UV analysis of phytochemicals demonstrating a high content of iridoids (177.18–641.04 μg/mL) and flavonoids (89.15–405.71 μg/mL). Additionally, mangiferin was detected in samples of G. triflora tea (19.89 μg/mL). Five free sugars (fructose, glucose, sucrose, gentiobiose, gentianose) were identified in all gentian teas studied, as well as six organic acids (malic, citric, tartaric, oxalic, succinic, quinic). Pectic polysaccharides with a high content of rhamnogalacturonans and arabinogalactans were also identified and characterized in gentian decoctions for the first time. Gentian tea decoctions and their specific compounds (gentiopicroside, loganic acid-6′-O-β-d-glucoside, isoorientin, isoorientin-4′-O-β-d-glucoside, mangiferin, water-soluble polysaccharides) showed a promising antimicrobial, anti-inflammatory and antioxidant potentials. Evidences obtained indicate the prospective use of gentian herb teas as food products and medicines.

Published: November 2015

Drug administration via the transdermal route is an evolving field that provides an alternative to oral and parenteral routes of therapy. Several microneedle (MN) based approaches have been developed. Among these, coated MNs (typically where drug is deposited on MN tips) are a minimally invasive method to deliver drugs and vaccines through the skin. In this review, we describe several processes to coat MNs. These include dip coating, gas jet drying, spray coating, electrohydrodynamic atomisation (EHDA) based processes and piezoelectric inkjet printing. Examples of process mechanisms, conditions and tested formulations are provided. As these processes are independent techniques, modifications to facilitate MN coatings are elucidated. In summary, the outcomes and potential value for each technique provides opportunities to overcome formulation or dosage form limitations. While there are significant developments in solid degradable MNs, coated MNs (through the various techniques described) have potential to be utilized in personalized drug delivery via controlled deposition onto MN templates.
S-s-s-syncopation: Music, Modernity, and the Performance of Stammering (Ca. 1860–1930)
Authors: Hoegaerts Josephine
Published: November 2015

The modern history of disability, and of speech impediments in particular, has largely been written as one of medical discourse and (more recently) of social and cultural imaginations. The pathology of speech appears as an embodied, but ultimately intangible, issue due to the transient nature of sound itself. Once produced, it disappears, and seems to escape memory. In this text, stammering is approached as an object of material history. Drawing on the “paper trail” left by medical experts, popular entertainers and a handful of stammerers’ experiences, this paper examines the ways in which stammering was made material in the nineteenth century. The impediment not only provided (pseudo) medical actors with a lucrative market for various curative objects and practices, but also propelled the (sheet-)music business. Stammerers themselves appear in this story of materialization and market as both agents and objects. The cheap self-cures, medical manuals, sheet music and (later) recordings that were produced not only for, but also by, them, show how easily the impediment was aligned with the modern consumer’s identity and how the persona of the stammerer was, ultimately, lodged in the Western collective memory in very material ways.

Published: November 2015

Exercise performance is partially limited by the functionality of the respiratory musculature. Training these muscles improves steady-state exercise performance. However, less is known about the efficacy of executing a respiratory muscle warm-up (RWU) immediately prior to high-intensity exercise. Our study purpose was to use a practitioner-friendly airflow restriction device to investigate the effects of a high, medium, or low intensity RWU on short, high-intensity exercise and pulmonary, cardiovascular, and metabolic function. Eleven recreationally active, males (24.9 ± 4.2 y, 178.8 ± 9.0 cm, 78.5 ± 10.4 kg, 13.4% ± 4.2% body fat) cycled at 85% peak power to exhaustion (TTE) following four different RWU conditions (separate days, in random order): (1) high; (2) medium; (3) low airflow inspiration restriction, or no RWU. When analyzed as a group, TTE did not improve following any RWU (4.73 ± 0.33 min). However, 10 of the 11 participants improved ≥25 s in one of the three RWU conditions (average = 47.6 ± 13.2 s), which was significantly better than (p < 0.05) the control trial (CON). Neither blood lactate nor perceived difficulty was altered by condition. In general, respiratory exchange ratios were significantly lower during the early stages of TTE in all RWU conditions. Our findings suggest RWU efficacy is predicated on identifying optimal inspiration intensity, which clearly differs between individuals.
Intermediary Propositions for Green Growth with Sustainable Governance
Authors: Choi Yongrok
Published: November 2015

This article gives an overview of the conceptual characteristics of sustainable development by searching the governance-oriented intermediaries. It shows how the new paradigm of green growth evolved through international consensus and how this paradigm of the public-private partnership (PPP) could work with the new propositions of intermediation. The historical context in the latter half of the 20th century is outlined, in which a paradigm shift toward PPP was caused by green growth policies. It emphasizes the governance, resulting in the propositions of the intermediary role of PPP by the SWOT matrix: facilitator, collaborator, network manager and service provider.
Concise Review: Asymmetric Cell Divisions in Stem Cell Biology
Authors: Murke Florian , Castro Symone , Giebel Bernd , Görgens André
Published: November 2015

Somatic stem cells are rare cells with unique properties residing in many organs and tissues. They are undifferentiated cells responsible for tissue regeneration and homeostasis, and contain both the capacity to self-renew in order to maintain their stem cell potential and to differentiate towards tissue-specific, specialized cells. However, the knowledge about the mechanisms controlling somatic stem cell fate decisions remains sparse. One mechanism which has been described to control daughter cell fates in selected somatic stem cell systems is the process of asymmetric cell division (ACD). ACD is a tightly regulated and evolutionary conserved process allowing a single stem or progenitor cell to produce two differently specified daughter cells. In this concise review, we will summarize and discuss current concepts about the process of ACD as well as different ACD modes. Finally, we will recapitulate the current knowledge and our recent findings about ACD in human hematopoiesis.
Studies on the Bioavailability of Deoxynivalenol (DON) and DON Sulfonate (DONS) 1, 2, and 3 in Pigs Fed with Sodium Sulfite-Treated DON-Contaminated Maize

Published: November 2015

Deoxynivalenol (DON) exposure of pigs might cause serious problems when critical dietary toxin concentrations are exceeded. As DON contamination of agricultural crops cannot be completely prevented, detoxification measures are needed. Wet preservation with sodium sulfite resulted in a significant DON reduction of naturally-contaminated maize in previous experiments. The preserved material had a characteristic DON sulfonates (DONS) pattern. DONS is known to be less toxic than DON but its stability was shown to depend on pH, which gives rise to the question if a back-conversion to DON occurs in vivo. Therefore, the toxicokinetics and bioavailability of DON and DONS were studied in pigs. After the administration of a single oral or intravenous bolus of DON or DONS, serial blood samples were collected and subsequently analyzed. DONS was not detectable after oral administration of DONS mixtures. The results showed further that the bioavailability of DONS as DON in pigs fed maize preserved wet with sodium sulfite was significantly decreased compared to untreated control maize (DON), indicating that DONS obviously did not convert back to DON to a large extent in vivo. Moreover, the fact that DONS was not detectable in systemic blood requires further investigations regarding their ingestive and/or metabolic fate.
De la conduite de réunion à la conduite de groupe
Authors: Rouchy Jean-Claude
Published: November 2015

La méthodologie de conduite de réunion que G. Palmade a conçue et développée avait pour objet principal une pédagogie de l’étude de problème. Notre conception du travail de groupe s’est enrichie et a changé d’objet, à la fois par des choix d’orientation psychanalytique et par une pratique dans le champ de la santé et du travail social. En nous référant aux concepts de « groupe de travail » de W.R. Bion, c’est la notion de « tâche » qui est devenue le critère à partir duquel les différents types de dispositifs de groupe sont répertoriés. Tout en gardant le fondement solide du cadre méthodologique, le travail de groupe peut concerner aussi bien des groupes thérapeutiques, des supervisions, des groupes à médiation, des groupes de formation ou d’intervention en institution. Le dispositif détermine l’espace analytique, la conduite du groupe et la place d’où l’on intervient. La topique de Bion ( work group, basic assumption, protomental ) donne une profondeur rationnelle, émotionnelle, somatopsychique à la conception de la conduite de groupe.
Filiation Freud-Ferenczi-Balint : fidélité et évolution en psychanalyse
Authors: Moreau Ricaud Michelle
Published: November 2015

On connaît la fidélité exemplaire de Michael Balint envers S. Ferenczi, son psychanalyste et ami de Budapest, qu’il n’a eu de cesse, dans son exil en Grande-Bretagne (1939), de faire connaître pour le réhabiliter dans la communauté analytique. Balint est non seulement son « passeur », mais également son « continuateur ». Il a pu réviser quelques-unes de ses positions théoriques, signaler ses erreurs, les corriger et les dépasser. S’il se disait marginal dans le courant des années 1960 à la British Psychoanalytical Society , était-ce dû à sa critique du concept freudien du narcissisme primaire, critique dans laquelle il n’était pas suivi ? Tout en restant freudien et ferenczien, n’apporte-t-il pas au corpus analytique de nouveaux concepts (« amour primaire », « les trois zones de l’appareil psychique », la « régression » bénigne ou maligne, le « défaut fondamental »), qui enrichissent et font évoluer la théorie de la psychanalyse et la manière de conduire les cures ?
Placements et déplacements de la psychanalyse
Authors: Sibony Daniel
Published: November 2015

Depuis ses origines, la psychanalyse a connu beaucoup de déplacements ainsi qu’une formidable extension dans le corps social, et les concepts freudiens sont devenus le bien de tous. La question de savoir ce qui demeure de ses invariants et ce qui a changé fait l’objet de cet article. L’ idée psy , que l’auteur assimile plus ou moins à la psychanalyse, ou à ce qu’il en reste dans la société contemporaine – essentiellement le transfert et l’interprétation –, continue à rendre possible une transmission symbolique dégagée des impasses du religieux et de la science. Les attaques dont la psychanalyse a fait l’objet révèlent le complexe du second premier, qui consiste à retourner contre elle des éléments qu’on lui a empruntés et baptisés autrement, comme c’est le cas dans beaucoup de psychothérapies. Le monde psy peut être compris comme le miroir ou le microcosme de la société dans lequel il prend place, et l’immense demande de psy comme un analyseur des pathologies du lien et de l’identité. L’auteur prône, pour le psychanalyste, une éthique de l’être, qui implique une forme de foi dans le possible et la capacité de tenir l’entre-deux entre la place et le déplacement.

L’auteure se propose de traiter de l’intérêt de l’extension du concept de transfert dans le champ de l’intervention sociale en revisitant la notion de transfert institutionnel. L’intervention conçue comme lieu déplacé du collectif institué permet l’analyse des normes et représentations des systèmes organisés telles qu’elles sont intériorisées par les acteurs sociaux. L’attention portée au processus transférentiel dans une intervention auprès de collectifs de travail ayant vécu le suicide d’un collègue ouvre à une compréhension de ce qui se donne comme énigmatique et ne peut être approché par une saisie directe.

Wandering spleen is a rare condition, characterized by a mobile spleen that is attached only by an elongated vascular pedicle, allowing it to migrate to any part of the abdomen or pelvis. Mesenteroaxial gastric volvulus usually occurs in children and may be associated with wandering spleen. Both entities result from abnormal laxity or absence of the peritoneal attachments due to abnormal fusion of the peritoneal mesenteries. Pancreatic volvulus is a very rare anomaly, with only a few isolated case reports described in association with wandering spleen. Anomalous right sided descending and sigmoid colon is a very rare entity and its association with wandering spleen has not been previously reported. We report a case of wandering spleen associated with mesenteroaxial gastric volvulus, pancreatic volvulus and rightward shift of the splenic flexure of the colon and right sided descending and sigmoid colon in a young female.

Published: November 2015

The promotion of the Internet of Things (IOT) in agriculture is an important symbol in the modern agricultural industry. It can efficiently lower the labor consumption and exert a positive impact on farmlands through wireless sensor networks. It can precisely acquire data on crops and the environment to achieve the scientific cultivation and management of the production equipment by means of automation, intelligence, and remote control and to advance the transformation of agricultural development in modern times. An intelligent system of high precision, which is based on the IOT, is formulated in this study. Such system applies Advanced RISC Machines (ARM) as its built-in gateway, with such carriers as Bluetooth, 2.4 GHz, Zigbee, Global System for Mobile Communications (GSM), Wi-Fi, and others, to establish wireless sensor networks and manage the agricultural production through remote control and intelligent management. The experiment suggests that the system can efficiently supervise and control the multiple environmental parameters and farmland equipment to meet the requirement of agricultural production.
Development of a Multibody Systems Model for Investigation of the Effects of Hybrid Electric Vehicle Powertrains on Vehicle Dynamics.
Authors: Bastin Matthew Andrew , Jones R Peter
Published: November 2015

With ever increasing numbers of Hybrid Electric Vehicles (HEV’s) being developed, come new challenges in the field of automotive engineering. Whilst there has been considerable work conducted on HEV’s from a powertrain, efficiency, and control systems perspective, very little work has been instigated in the field of how the introduction of such hybrid systems effect passive vehicle dynamics. One of the possible obstacles in the way of such studies is the multitude of powertrain architectures that are present or possible in HEV’s. This obstacle can make investigations very application specific, and leads to inefficiencies in the modelling process.

This paper discusses the development of a model constructed in Dymola in order to investigate the effects of hybrid powertrains on ride and handling. The modelling methodology is presented, along with model based testing and validation of component and the full vehicle models.

Whilst the development of the model is introduced for a specific study, it is shown that the way in which the model has been developed lends itself easily to use in other fields. It is shown that the modular construction of the model, and the physical, object orientated modelling approach facilitated by Dymola, allow varying numbers and complexities of component models to be utilised within the same basic model. Such an approach means that one base model can be utilised for differing hybrid architectures for ride, handling and drivability studies thus reducing modelling time and complexity.
On-line Signature Verification Based on GA-SVM
Authors: Huang Dong , Gao Jian
Published: November 2015

With the development of pen-based mobile device, on-line signature verification is gradually becoming a kind of important biometrics verification. This thesis proposes a method of verification of on-line handwritten signatures using both Support Vector Data Description (SVM) and Genetic Algorithm (GA). A 27-parameter feature set including shape and dynamic features is extracted from the on-line signatures data. The genuine signatures of each subject are treated as target data to train the SVM classifier. As a kernel based one-class classifier, SVM can accurately describe the feature distribution of the genuine signatures and detect the forgeries. To improving the performance of the authentication method, genetic algorithm (GA) is used to optimise classifier parameters and feature subset selection. Signature data form the SVC2013 database is used to carry out verification experiments. The proposed method can achieve an average Equal Error Rate (EER) of 4.93% of the skill forgery database.
Vulnerability to Local Climate Change
Authors: Swain Mrutyunjay
Published: November 2015

The paper analyses the perceptions of the farmers on various aspects of present as well as future vulnerability to local climate change in western Odisha, India. The changes in various climatic factors like rainfall, temperature, drought frequency and intensity during last three decades have been assessed. The farmers' experiences on hardships faced, natural and human induced causes of the changes observed have been examined. The perceptions on changes/trend in various vulnerability factors such as water availability, soil quality, early warning system, deforestation, social safety nets, institutional support system, degradation of wild life habitat, loss of wetland and water bodies, and damage to plant species etc. have been scrutinized. Besides, the future vulnerability to climate change has been assessed by ranking the vulnerability factors (economic/environmental/social/institutional) with respect to their effects during past, present and future climatic risks in the matrix form, thereby identifying the vulnerability factors posing greater threat in future. The study is based on the survey of 139 households. The study finds significant changes in behavior of climatic factors in western Odisha. The factors that are posing greater threat in future are increasing temperature and rainfall variability, frequent pest attack and plant diseases, gradual decline in grazing land and fodder availability, reduction and degradation of wild life habitat and loss of wetland and water bodies.

Published: November 2015

The reported economic losses due to natural disasters show an increasing trend over time for India. This is due to the influence of three factors: bio-physical drivers, exposure and vulnerability. Normalising the influence of exposure and vulnerability of socio-economic factors, this chapter potentially detects the influence of climate, caused by natural climate variability as well as anthropogenic climate change, in determining the damages from natural disasters. It analyses the trends in both the reported and normalised economic losses from natural disasters in India during 1964 and 2012. Similar analysis is also carried out for a subset of major disaster events like cyclonic storms and floods. No significant trend is found either for the normalised damage costs from natural disasters or for individual extreme events like floods and cyclonic storms. The findings suggest that the increases in damage costs is due to higher exposure and vulnerability of the socio-economic conditions of those affected, and recommends for additional investments on infrastructure to strengthen the adaptive capacity of the vulnerable sections with respect to the socio-economic factors.

Authors: Swain Mrutyunjay , Swain Mamata
Published: November 2015

The paper analyses the major role played by the institutional support system such as government safety nets, non-governmental and community based insurance mechanism in strengthening the coping capacity of rural households facing recurrent drought in Bolangir district of western Odisha. The gradual refinement of drought management policies and the role played by centre-state relationship and power equations in implementation of programmes for effective drought management have been critically examined. In addition to analysis of secondary data and literature, the primary survey data on 139 households have been analyzed to assess the role of institutional support system in building up their resilience. The institutional support system was found to be weak to withstand drought in effective manner in the study region. A gradual improvement to the drought management policies was observed and every major drought resulted in some qualitative improvement to the relief approach. However, the implementation of the development schemes was affected by the power politics.
Bioeconomic Fishery Management
Authors: Gupta Anita Chattopadhyay
Published: November 2015

Coastal areas are also important ecologically, as they provide a number of environmental goods and services. Potentially, if managed sustainably, they can provide continuing returns without any decrease in their productivity. But, the unfolding state of coastal ecosystems, from the standpoint of fisheries production, is causing concern. A move towards fishing management that conserves biodiversity, permits sustainable utilization and recognizes the importance of species interaction is worthwhile. Recent recognition of such interactions in fishing has resulted in calls for adoption of ecosystem approaches to fishery management to rebuild and sustain populations, species and biological communities at high levels of productivity and biological diversity. The coupling of fishery management issues more directly with the issues of marine pollution, and biodiversity represents an increasing understanding of the linkages among them. This calls for changing fishery management paradigms towards a more coherent ecosystem approach.

Published: November 2015

Increasing evidence shows that shifts in Earth's climate have already occurred and indicates that changes will continue in the coming years. This chapter is an attempt to distil what is known about the likely effects of climate change on food security and nutrition in coming decades. Apart from few exceptions, the likely impacts of climate change on agricultural sector in the future are not understood in any great depth. There are many uncertainties as to how changes in temperature, rainfall and atmospheric carbon dioxide concentrations will interact in relation to agricultural productivity. The consequences of climate change on various important aspects of agriculture such as crop production, livestock, availability of water, pest and diseases etc. are discussed and summarized. Each of this aspect of agriculture sector will have certain impact which may be positive or negative. The chapter also discusses on the possible mitigation measures and adaptations for agriculture production in the future climate change scenarios.

Published: November 2015

Africa continues to experience serious signs of multiple crises in the context of sustainability. These crises include vulnerability to climate change, rapid urbanization, food insecurity, and many others. One crisis, that defines Africa today, is the unprecedented rapid urbanization which continues to pose a big challenge to the diminishing available resources, environmental quality and human well-being. Cities in Africa continue to experience a fast horizontal growth of settlements due to influx of people from rural areas who often settle in the economically lowest segments in urban areas. This horizontal rapid growth has eaten up land set for agriculture around cities and promoted the rapid growth of informal settlements exacerbating the impacts of climate change leading to a negative impact on agricultural production. Policies linking rapid urbanization and climate change with agricultural productivity are need. This paper explores and documents the impact of rapid urbanization on climate change policies and subsequent impact on agriculture in Africa.
