Chitosan hydrogel-based electrolyte for clean and biodegradable batteries: energetic and conductometric studies

ABSTRACT Measurements of voltages generated in clean and biodegradable batteries using lithium-chitosan as electrolyte, carbon and nickel as electrodes, were reported. They produced small amounts of energy providing environment was preserved. The energy smallness was argued by conductivity measurements. The concentration and temperature dependences were undertaken. These measurements were carried out from 0.0005 to 1.0 mol dm−3 in the temperature range 258–323 K, and were compared to glycerol, being clean viscous solvent. The purpose was to substitute toxic solvents currently used, by clean and biodegradable solvents having good performances. The results were analysed with Debye–Huckel–Onsager law at low concentrations and Quasi–Lattice Model at moderate and higher concentrations. The temperature dependence of conductivity was also described using Vogel–Tamman–Fulcher equation. By comparing it to Arrhenius theory, very interesting parameters, such as electrical conductivity infinite dilution, activation energy and Vogel temperature, corresponding to glass transition temperature were extracted from the fit of experimental data.
Etiological Profile and Clinical Outcomes of Bacterial Keratitis from a Tertiary Care Centre in North Kerala

Corneal ulcer is a leading cause of ocular morbidity and monocular blindness worldwide. To effectively prevent blindness in patients with corneal ulcer, a proper understanding of risk factors predisposing to ulceration, its clinical and microbiological characteristics are essential. Timely identification of aetiological agents causing corneal ulcer and their prompt treatment helps to save the vision. A cross sectional study was conducted in Government Medical College, Kozhikode, between January 2016 to June 2017 to detect bacterial agents of corneal ulcer and determine the antibiotic susceptibility pattern of those isolates. All patients who were clinically diagnosed as cases of infectious corneal ulcer in the Ophthalmology department, Government Medical College, Kozhikode were included in the study. Corneal scrapings collected from the infected eye were subjected to microbiological examination and culture. Among the 120 cases, a total of 27 cases were culture positive. 21/120 [17.5%] were bacterial, 6/120 [5.0%] were polymicrobial and 22/120 [18.34%] were fungal. Among bacterial aetiology, Pseudomonas aeruginosa was most common [33.34%] followed by Coagulase negative Staphylococcus-22.23% and Streptococcus pneumoniae-18.51%. Trauma was the major risk factor. Diabetes mellitus, contact lens usage, exposure keratitis were the other comorbidity / risk factors. Out of the total 27 culture positive bacterial corneal ulcer cases none healed completely, 77.78% improved clinically with opacity and 22.22% ended with recurrence/complications. This study shows majority of infected corneal ulcers are associated with risk factors and the aetiology are mainly due to bacteria. Corneal ulcers responded well to antimicrobials except a few complicated ulcers. Microscopy, culture and clinical correlation helped in adequate management. Thus, prognosis and outcome of corneal ulcers rely on timely identification of their aetiology and prompt treatment.
Impact of Structural Dynamics on the Optical Properties of Methylammonium Lead Iodide Perovskites

Organolead halide perovskites have attracted a lot of attention over the recent years mostly due to their bright prospective application in photovoltaic devices. For further development, characterization of their physical properties plays a seminal role in order to gain an in‐depth understanding of these mid‐bandgap ionic semiconductors. Their unique optical and electronic properties are a result of their characteristic electronic structure. Temperature dependent optical spectroscopy, i.e., absorption and photoluminescence (PL) characterization, gives access to their electronic nature that draws strong correlations to their structural properties. Those properties include static and dynamic disorder, and defects or phase transitions, which will be demonstrated in the first part of this research view. The second part focuses on ion migration in these hybrid semiconductors, which can strongly affect the slow dynamics of optical properties. Light‐activated ions result in a number of complex processes that can lead to an increase, but also a decrease of PL intensity, or induce PL intermittency. Parameters like light intensity, crystal quality, and defect density all influence these processes, and ultimately the electronic nature of the hybrid perovskites. We will briefly summarize current achievements and point out challenges for upcoming research.
“Should I stay, or should I go?”: The mobility paradigm in widening participation for regional, rural and remote students

This paper examines the key question that rural, regional and remote (RRR) students face when they are considering their post-secondary education pathway: “Should I stay in my community, or should I leave? ”. It considers the last thirty years of Australian higher education policy to explore how policy discourses have re/produced this ‘mobility paradigm’, where success for RRR students is defined by leaving their local communities. Australian RRR student identity has been discursively constructed in a way that provides the illusion of autonomy in post-secondary choice for students, but surreptitiously channels individuals into prescribed pathways through a process of differentiation and exclusion. These prescribed ‘successful’ pathways over-emphasise the need for students to leave communities when considering post-secondary study options – irrespective of what educational choices are locally available. The analysis in this paper draws on Foucault to unpack how RRR student identity has been historically constructed in Australia and offers directions for reconceptualising how education policy has affected RRR student participation in higher education and their geographic mobility.
The role of microcredit in promoting self-employment in urban area : Lesson from Amanah Ikhtiar Malaysia (AIM), Malaysia / Siti Noor Shamilah Misnan...[et al.]

Some scholars’ view of microcredit’s potential as a tool of enhances the quality of life and poverty alleviation. Microcredit scheme create opportunities for participants to get involved in the self-employment and involved in the entrepreneurship programme. It seem that this scheme create an opportunities for the participants to be independent in creating self-economic. In the case of Malaysia, AIM’s microcredits program is a group-based lending and become a platform to produce entrepreneur as well as antipoverty intervention and increasing the quality of life and social empowerment. Traditionally, microcredit aims to break the rural poor in developing countries especially groups of unable to access bank loans and poor villagers rely on local moneylenders. For this situation, microcredit provides an alternative source of credit and offering collateral-free loans. Currently, there are debates of urban poverty and role of microcredit to empower this group. Previous studies showed that microcredit has changed the socio-economic of the participant in increasing empowerment, entrepreneur skills, transformational thinking and a desire to improve get out from poverty. Thus, this conceptual paper will study and discuss the mechanism of promoting self-employment in urban area. Following discussion of this concept paper of microcredit is expected to give implication to policy maker, agencies that offers micro credit, as well as for the community in general.

A high pressure La K-edge X-ray absorption fine structure spectroscopy investigation of La1/3NbO3

ABSTRACT La K-edge X-ray absorption spectroscopy has been used to elucidate the changes in the local electronic and lattice structure that occur in the A-site deficient double perovskite LaNbO up to 6 GPa. The pressure evolution of the oxygen dodecahedrum around the A-site has been examined. XANES (X-ray absorption near edge structure) data show modifications ascribed to the increase of bands overlapping as a consequence of the bond distance contraction, which has been directly probed by EXAFS (extended x-ray absorption fine structure) spectra. The La–O Debye Waller factors (DWFs) tend to increase whereas the La–Nb bond DWFs show only a tendency to decrease indicating the robustness of the crystal lattice structure, even in presence of the oxygen disordering. This permits the system to reverse back to its original conditions in this pressure range as evident from the measurements upon pressure release. The present results have been interpreted in the light of charge transfer related to the two-step reduction mechanism acting at the Nb site (with niobium ions passing from Nb to Nb) which also results in the elongation of the Nb–O bond distances in the octahedra, in agreement with the Nb K-edge results reported earlier.
Solid-state production of complex organic molecules: H-atom addition versus UV irradiation

Abstract Complex organic molecules (COMs) have been observed in comets, hot cores and cold dense regions of the interstellar medium. It is generally accepted that these COMs form on icy dust grain through the recombination reaction of radicals triggered by either energetic UV-photon or non-energetic H-atom addition processing. In this work, we present for the first time laboratory studies that allow for quantitative comparison of hydrogenation and UV-induced reactions as well as their cumulative effect in astronomically relevant CO:CH3OH=4:1 ice analogues. The formation of glycolaldehyde (GA) and ethylene glycol (EG) is confirmed in pure hydrogenation experiments at 14 K, except methyl formate (MF), which is only clearly observed in photolysis. The fractions for MF:GA:EG are 0 : (0.2-0.4) : (0.8-0.6) for pure hydrogenation, and 0.2 : 0.3 : 0.5 for UV involving experiments and can offer a diagnostic tool to derive the chemical origin of these species. The GA/EG ratios in the laboratory (0.3-1.5) compare well with observations toward different objects.
Stories of Madness: Exploring Resistance, Conformity, Resiliency, Agency, and Disengagement in Mental Health Narratives

Old and present mental health systems tend to emphasize mental health service users as passive recipients of psychiatric care, which suppresses the idea that people who experience serious mental illness are able to comprehend their own sickness and recovery and therefore engage psychiatric experts about their care. This dissertation seriously interrogates the ways in which those who experience serious mental illness become agential, resist some of the control mechanisms, relationships of power, and infantilizing rituals found within the Canadian mental health system, and survive abject circumstances. Drawing on my own autoethnographic experiences with psychosis and psychiatric hospitalization, as well as 10 interviews with mental health service users, I argue that narrative approaches to inquiry and a post-anarchist praxis can reveal and liberate our agential capacities to recover and live through madness that otherwise become less known through biomedical approaches to mental health research. I identify some of the porous boundaries between the livable and unlivable forms of madness, and explore the complex relationships between service users and their caregivers whose penultimate goal is to help us live a manageable life. I conclude by discussing the contributions of this dissertation and reflect on some of the practical needs of the current mental health system.
Comparative assessment of response surface methodology quadratic models and artificial neural network method for dry reforming of natural gas

ABSTRACT The performance of 0.5% wt Rh/γ-AL2O3catalyst for the dry reforming of natural gas using carbon dioxide has been considered. In the present work a comparative study has been performed using Radial Basis Function Neural Network (RBFNN) and Response Surface Methodology (RSM) quadratic models to investigate their predictive ability for the effect of two different operating parameters, naSSSmely the hourly space velocity and the reaction temperature on the conversion of the different components comprising commercial natural gas. The predictive capabilities of the two methodologies were compared employing statistical error functions. The results indicated the superiority of RBF in the prediction capability; for example, the F-ratio for the CH4 reactant is 86 and 1088185 employing RSM and ANN methods, respectively. Also for the various components involved in the reaction system R2 ranges from 0.74 to 0.96 in case of RSM while it is 1.0 for all components employing ANN. This is due to ANN ability to approximate the non-linearity between the input and output variables.
Studying Media Polarity Effects on the Photo-Physical Behaviors of Organometallic Complexes with Azo-Containing Schiff-Base Ligands

Abstract Solvent molecules as an important factor can modify the photo-physical behavior of organometallic complexes. For precise investigation, in this paper, the spectral behavior of some groups of copper complexes with different substituents were studied in various solvent media. In this case, the linear solvation energy relationships concept was used for determination of various contribution of media induced specific and non-specific interactions on the photo-physical behavior of various forms of organometallic complexes with azo-containing Schiff-base dyes. Moreover, the calculated dipole moments indicate that samples with different forms tend to have polar structure in the excited state as compared to those in the ground state. By exploiting of calculated dipole moments and obtained quantitative results in the ground and excited states, the dominant solvent induced resonance structures were also estimated. The obtained experimental results can give more information about how these samples can behave in various physical, chemical and biological phenomena.

Standardization of tinting techniques in gerbera, carnation and gladiolus

An investigation was carried out to study the vase life, colour intensity, moisture content of tinted gerbera, carnation and gladiolus flowers. The experiment comprised of two factors i.e., first one was flowers treated with six food dyes with 5% concentration along with control and with three different time of immersion for 2.5, 5.0 and 7.5 hrs. The results revealed that flowers treated with distilled water (Control) and immersed for 2.5 hrs had recorded the higher vase life (7, 8 and 6 days), maximum mean moisture content (60.3, 64.8 and 57.71%) in gerbera, carnation and gladiolus respectively. With respect to the colour intensity, colour distribution and consumer acceptability the flowers treated with blue, orange and green dyes which were immersed for about 7.5 hrs duration had recorded the higher consumer acceptance. The flowers which were treated with blue, green and orange (1.30, 1.40 and 1.50 hrs) (1.20, 1.39 and 1.48 hrs) and (50min, 58min and 1.23 hrs) were found to absorb the dyes quickly in gerbera, carnation and gladiolus respectively, Thus it can be concluded that tinting with blue, green and orange which were immersed for 7.5 hrs duration had gained the maximum consumer preference with bright attractive flowers.
Higher rate of Epstein-Barr virus incorporation on decidualendometrial cells in pregnant women with preeclampsia

Introduction: There are various theories regarding the pathogenesis and pathophysiology of preeclampsia, but the exact cause of preeclampsia is not yet clearly established. Previous investigators have suggested that preeclampsia may be associated with Epstein-Barr virus (EBV) infection in the B lymphocytes during pregnancy based on polymerase chain reaction or serological tests. The purpose of this study was to evaluate the prevalence of EBV-positivity in women diagnosed with and without preeclampsia using placental specimens. Materials and methods: This retrospective study included 85 pregnant women with preeclampsia and 65 pregnant women without preeclampsia. Placental specimens were assessed for the presence of acute and chronic inflammation. EBV-positivity was evaluated using in situ hybridization on EBV genes from tissue microarray slides. Clinicopathological characteristics were compared between women with and without preeclampsia and between EBV-positive and EBV-negative women. Results: Women with preeclampsia showed a higher occurrence of EBV-positive cells than those without preeclampsia (36.5% vs 20.0%, p = 0.028). When stratified into gestational age, the occurrence of EBV-positivecells were consistently higher in women with preeclampsia with preterm delivery (39.1% vs 20.0%, p = 0.042) but not in those with full-term (28.6% vs 20.0%, p = 0.497). Conclusion: We found increased EBV infected placenta of women with preeclampsia compared with those without preeclamplasia. Further study is needed to elucidate the etiological role of EBV infection during development of preeclampsia.

In this paper we give a survey of the known properties of the Bruijn and Kautz networks showing that their behavior is as good as the hypercube's. As they have the advantage of connecting considerably more processors, they are good competitors for the hypercube and might constitute the next generation of parallel architectures.
Evaluation of performance of blends of green gram Vigna radiata (L.) Wilczek relative to their component cultivars in pure stands

The present work was carried out during 2016 at ICR Farm (Instructional Cum Research), Assam Agricultural University, Jorhat, Assam. Four green gram “[Vigna radiata (L.) Wilczek]” varieties viz.,Pratap (V1), K851 (V2), SGC 16 (V3), SGC 20 (V4) and their six equiproportional blends B1 (Pratap and K851), B2 (Pratap and SGC 16), B3 (Pratap and SGC20), B4 (K851 and SGC16), B5 (K851 and SGC 20), B6 (SGC16 and SGC 20) were studied in six environments to accesses the performance of blends relative to their component cultivars in pure stands. The twelve different characters viz., days to first flower bud initiation, days to first pod initiation, 75 % pod maturity, plant height, primary branches, secondary branches, clusters per plant, pods per plant, seeds per pod, hundred grain weight, grain yield per plant and number of nodules were observed at different growth stages. The mean performance of the genotypes under study revealed that blends performed better than the pure stand cultivar for different characters except seeds per pod and plant height. The blend cultivar B4 (K851 and SGC16) produced highest seed yield per plant. Other genotype such as Pratap (V1), Pratap and 851 (B1), Pratap and SGC16 (B2), SGC 16 and SGC20 (B6) were found promising for seed yield. The information generated from the study helpful for the pulse breeders to address a few issues in order to enhance green gram productivity through an approach of developing appropriate varietal blends.
Effect of excess zinc and arbuscular mycorrhizal fungus on bioproduction and trace element nutrition of Tomato (Solanum lycopersicum L. cv. Micro-Tom)

ABSTRACT The effect of excess Zn and arbuscular mycorrhizal (AM) fungus on bioproduction and trace element nutrition were investigated in tomato. In a completely randomized factorial design, the experimental treatments – Zn addition at 0 (normal) and 300 (excess) mg Zn kg−1 soil, and AM inoculation (non-AM and Rhizophagus irregularis) – were set up in a growth chamber for 10 weeks. Generally, AM effects on the available Zn, Mn, Cu, and Fe in the rhizosphere soil were in tandem with the effects in host tissues. Under normal Zn condition, AM enhanced Cu availability in the rhizosphere, optimized the Cu:Zn balance in shoots, and increased the host biomass production. Excess Zn reduced mycorrhizal colonization in AM plants and the total plant biomass in both AM and non-AM plants. Although AM decreased the Zn concentrations in soil and host tissues under excess Zn, the distortions in host TE balance were not significantly ameliorated by the fungus. While Zn in fruit was within the safety threshold, Mn deficiency in the fruit was observed under excess Zn, alongside increased root-to-fruit Fe and Cu translocations. Mycorrhizal reductions in soil and tissue Mn concentrations were considered a minus in terms of probable symbiont amelioration of Mn:Zn in-balance under excess Zn. Additional microbe(s) that can enhance Mn homeostasis might be helpful in tomato under elevated soil Zn.
