Determination of seasonal and developmental variation in oxalate content of Anagallis arvensis plant by titration and spectrophotometricmethod

Oxalates are one of the important toxicant from veterinary toxicology aspect as they are mostly related to nephropathy and kidney failure. The reasons behind these clinical signs are accumulation of oxalate crystals in the filtration units of body and damaging renal tubular epithelium. In the present study, oxalate content of mature and immature plants was estimated by 2 methods; permanganate titration and spectrophotometric method. The quantitative precipitation of oxalate as its calcium salt, followed by permanganate titration was done. This method presents little difficulty in aqueous solutions, and quantities of oxalic acid as low as 0.05 mg may be estimated with accuracy. With this standard titration method, the estimated oxalic acid content was 14.79% for mature plant parts (month of March) and 12.45% for immature (month of November) plant parts. Though it was most accurate process but time consuming, so spectrophotometric method was tried for evaluating the efficacy. In this method 0.5g of plant material was taken and the concentrations of oxalate were estimated in the plant extract and it was found to be 15.06% and 12.68% for mature and immature plant parts respectively. From this study it can be concluded that mature plant parts contains more oxalate than immature plant parts. Also regarding estimation methods, spectrophotometric method is better method than traditional titration method in the modern research field with little difference in accuracy but more effective.
A novel mechanism for outbursts of Comet 17P/Holmes and other short-period comets

A mechanism is proposed to explain the outburst of comet 17P/Holmes based on; (a) oxidation of water within the porous surface of the comet nucleus to form hydrogen peroxide (H2O2) through exposure to UV radiation, to energetic solar-wind particles and to cosmic radiation, (b) concentration of the H2O2 component through solid-, liquid- and gas-phase processes involving sublimation, evaporation, fractional crystallization, diffusion, supercooling, capillary wetting and migration in voids within the nucleus, and (c) rapid exothermic decomposition of aqueous H2O2 liberating oxygen gas via a surface catalytic reaction through interaction with finely-dispersed transition metals, metal compounds and minerals, in particular those containing Fe, localised within a differentiated multicomponent comet nucleus. An accelerated release of gaseous oxygen, concomitant self-heating and volatilisation of hydrocarbons within the nucleus results in its explosive disruption. This mechanism may also explain the observation of a repeat outburst of this comet in 1893. Laboratory studies to investigate H2O2 formation in simulated cometary environments and to evaluate H2O2 decomposition on meteoritic samples are recommended.
HOMOGENIZATION WITH MULTIPLE SCALE EXPANSION ON SELFSIMILAR STRUCTURES

The Job Demands-Resources model as predictor of work identity and work engagement: A comparative analysis

Orientation: Research shows that engaged employees experience high levels of energy and strong identification with their work, hence this study’s focus on work identity and dedication. Research purpose: This study explored possible differences in the Job Demands-Resources model (JD-R) as predictor of overall work engagement, dedication only and work-based identity, through comparative predictive analyses. Motivation for the study: This study may shed light on the dedication component of work engagement. Currently no literature indicates that the JD-R model has been used to predict work-based identity. Research design: A census-based survey was conducted amongst a target population of 23134 employees that yielded a sample of 2429 (a response rate of about 10.5%). The Job Demands- Resources scale (JDRS) was used to measure job demands and job resources. A work-based identity scale was developed for this study. Work engagement was studied with the Utrecht Work Engagement Scale (UWES). Factor and reliability analyses were conducted on the scales and general multiple regression models were used in the predictive analyses. Main findings: The JD-R model yielded a greater amount of variance in dedication than in work engagement. It, however, yielded the greatest amount of variance in work-based identity, with job resources being its strongest predictor. Practical/managerial implications: Identification and work engagement levels can be improved by managing job resources and demands. Contribution/value-add: This study builds on the literature of the JD-R model by showing that it can be used to predict work-based identity.

Variations in salinity tolerance of selected mango rootstocks

An experiment was conducted at the Germplasm Centre, Department of Horticulture, Patuakhali Science and Technology University (PSTU) during the period from July 2011 to March 2013 to study the performance of selected mango rootstocks in the saline area in Bangladesh. The experiment consisted of four mango rootstock lines collected from Rangpur, Dumki, Khulna and Kuakata, and five salinity treatments namely control (0 dSm -1 ), low (4 dSm -1 ), medium (6 dSm -1 ), high (8 dSm -1 ) and very high (10 dSm -1 ). A two factor experiment was conducted in a Randomized Complete Block Design (factorial) with four replications. Results revealed that rootstock line and salinity levels had significant influences on various crop characters viz. length of rootstocks, diameter of rootstocks, number of leaves and percent rootstocks success and survivability. In case of rootstocks, the longest rootstock length (41.38 cm), highest number of leaves (37.58) and survivability (71.73%) were recorded in Rangpur line. In case of salinity treatments, rootstock diameter (16.09 mm), number of leaves/graft (36.47) and survivability (67.37%) were recorded in low salinity treatment. Interaction of rootstock lines and different salinity treatments showed significant variation on the length and diameter of rootstocks at 120 DAT. The maximum diameter of rootstock (17.63 mm) was recorded in high (8 dSm -1 ) salinity treatment in rootstock line of Kuakata, followed by the same stages of rootstock lines of Khulna (17.56 mm). The longest rootstock (46.75 cm) was recorded in control treatment (0 dSm -1 ) with rootstock line of Rangpur followed by the same stages of rootstock (41.75 cm) with medium salinity treatment (6 dSm -1 ). Rangpur rootstock line performed best from 0-8 dSm -1 salinity. The overall salinity tolerance was graded as follows: Rangpur rootstock line > Dumki rootstock line > Kuakata rootstock line > Khulna rootstock line. Bangladesh Agron. J. 2014, 17(1): 89-94
A Theory of the Emergence of Compulsory Education Laws

This paper explores the dynamics of voting over mandatory education when parents allocate children's time between school and labor. When poverty keeps a sufficiently high number of children at work rather than in school, the availability of forms of child labor that provide skill-enhancimg learning-by-doing cam be essential for compulsory education laws to emerge in a steady state. In poor countries where poor children are involved in th forms of child labor that provide too little or no learning-by-doing, such laws may fail to win political support thereby causing the economy to fall into a poverty trap. This paper therefore support the view that certain forms of child labor, particularly the most harmful ones should be banned, to allow poor family children to enter only those forms of child labor that provide learning-by-doing.
Acute Scrotum during the First Year of Life

Objective: The aims were to characterize spermatic cord torsion (SCT), to compare it with other causes of acute scrotum during the first year of life and to describe the distinctive features of each causative group. Material and Methods: Ninety-one consecutive neonates (44) and infants (47) were operated on for acute scrotum and the definitive diagnoses for the testicles thus confirmed. The duration of the symptoms and the physical findings were recorded. The histopathology of the removed testicles was studied and bacterial cultures were obtained from patients with epididymitis (ED). Results: Thirty-five boys (39%) had SCT, and incarcerated inguinal hernia (IH) and epididymitis were found in 22 (24%) and 21 (23%) cases, respectively. Torsion of the testicular appendage (TAT) was only seen once. A dark, hard testicle was observed in 91% of the SCT patients, but erythema and tenderness were infrequent. 30 out of 39 (77%) patients had SCT during the neonatal period, including 15 cases in which torsion had occurred prenatally. Only four testicles (11.4%) with SCT were salvaged. Conclusions: The cause of acute scrotum during the first month of life was mostly SCT, while ED was seen more frequently between the ages of 3 and 6 months. A dark, hard testicle was a common finding in the SCT patients, while swelling and erythema were typical of ED. Neonatal SCT has a poor prognosis.
CHAPTER IV PHYSICAL AND SENSORY MEASUREMENTS OF DIPPING CHARACTERISTICS OF LACTOSE-HYDROLYZED ICE CREAM

Ice cream mixes were treated with lactase (EC 3.2.1.23) from the microbial sources Kluyveromyces lactis and Aspergillus oryzae to cause 0 to 100% lactose hydrolysis. Compression measurements and yield stress as measured by the vane method were both affected by the temperature of the samples. R 2 values for compression measurements as related to lactose hydrolysis were higher then those obtained for yield stress. Human evaluation determined a difference (p < 0.05) between the control samples (0% hydrolyzed) and the treatment groups (80% and 100% hydrolyzed).
Sociological Variables Perceived in the Study of Ghanaian languages in Central and Western Regional Colleges of Education in Ghana

The study was conducted in two Colleges of Education in the Western and Central Regions of Ghana to find out how Colleges of Education students and tutors perceive the study of Ghanaian Languages. The target population comprised all staff and students of the Colleges of Education but the accessible population comprised students and tutors of the two Colleges. The purposive and simple random sampling techniques were used to select the students and tutors. The sample size that participated in the study was 280 students and 32 tutors. Among the findings were that Ghanaian Languages are not taught in very practical ways, most students and tutors had a positive perception of students of Ghanaian Languages, students and tutors did not show disrespect to students offering Ghanaian Languages.
GOCE radar-based Orbit Determination for Re-Entry Predictions and comparison with GPS-based POD

During the last days of its re-entry phase, GOCE was tracked by several on-ground and in-orbit instruments, mainly radar and GPS. The availability of such a rich data set at low altitudes provides a unique opportunity to gain insight in the field of re-entry analysis. This study aims at understanding if general re-entry prediction strategies can be improved, especially from the point of view of orbit determination techniques. Precise orbits from continuous GPS measurements are compared with orbits determined from singleand simulated multi-sensor radar measurements. The conclusion is that, provided a proper observational frequency, even sparse radar tracking can give comparable information to continuous on-board GPS solutions, if the goals are re-entry predictions and average ballistic coefficient estimation. At low altitudes, large intrinsic uncertainties in the dynamical models dominate over the observational errors, affecting orbit precision, measurement residuals and limiting predictions accuracy. For this reason, to guarantee observational sessions up to few hours before re-entry is always recommended to reduce the size of re-entry windows.
Maximizing strategic alliances in the multi-sided platform firms

The growth of multi-sided platform (MSP) firms, especially those with high Internet utilization such as Uber, Tokopedia, Go-Jek as well as other sharing economy firms, started to catch the attention of strategic management scholars. Since multi-sided platforms have more than one distinct user side with various role in the business ecosystem, the strategic alliances between the MSP and its platform members may play a significant role in increasing the user base as well as the value of the platform itself. However, there are still few researches that discuss the strategic alliances within the MSP. For this reason, this conceptual article aims at mapping the strategic alliances literature relevant to the MSP context through in-depth literature review. Two case analyses from high growth MSP firms in Indonesia are presented to explain this phenomenon.
Remittances and the Impact on Crime in Mexico

This working paper studies the effect of remittances from the United States on crime rates in Mexico. The topic is examined using municipal-level data on the percent of household receiving remittances and homicides per 100,000 inhabitants. Remittances are found to be associated with a decrease in homicide rates. Every 1 percent increase in the number of households receiving remittances reduces the homicide rate by 0.05 percent. Other types of crimes are analyzed, revealing a reduction in street robbery of 0.19 percent for every 1 percent increase in households receiving remittances. This decrease is also observed using a state-level panel in another specification. The mechanisms of transmission could be related to an income effect or an incapacitation effect of remittances increasing education, opening job opportunities, and/or reducing the amount of time available to engage in criminal activities.
Activity Based Travel Demand Model System with Daily Activity Schedules

We present an integrated activity based discrete choice model system of an individual's daily activity and travel schedule, intended for use in forecasting urban passenger travel demand. The system is demonstrated using a 1991 travel survey and transportation system level of service data for the Boston metropolitan area. The model system is implemented as a set of choice models, integrated as a sequentially estimated nested logit model system. Three types of models comprise the system: (1) daily activity pattern, (2) primary tour and (3) secondary tour. The daily activity pattern decision includes the decision of whether to travel, the choice of the day’s primary activity, the complexity of the primary tour and the number and purpose of additional tours. The primary and secondary tour models include the choice of time, destination and mode of travel. The tour models are conditioned by the choice of a daily activity pattern, and the choice of a daily activity pattern is influenced by the expected maximum utility derived from the available tour alternatives. The expected maximum utility derived from the tour alternatives varies for different daily activity patterns, as does the change in expected maximum utility when environmental and socioeconomic changes occur. Thus, for example, increases in fuel prices would reduce the utility of high mileage daily activity patterns more than that of low mileage patterns. This would cause a predicted shift toward the lower mileage patterns, such as those which chain activities in fewer tours or substitute in-home activities for those which require travel. The daily activity schedule model system can be used for forecasting travel demand by generating origin destination trip tables by time of day, using the method of sample enumeration, also known as microsimulation. The expected benefit of the daily activity schedule model system is improved travel demand forecasts, in comparison to trip and tour based models in use today, for policy alternatives such as 1) roadway expansion 2) employer provided carpooling incentives, and 3) increased fuel prices. It should also yield improved emissions estimates under all policy scenarios. Thesis Supervisor: Dr. Moshe Ben-Akiva Title: Professor of Civil and Environmental Engineering

Metazoos parásitos de “Caballa” Scomber Japonicus houttuyn, 1782 (Perciformes: Scombridae) del Puerto de Chicama, La Libertad, Perú

This study quantifies the metazoan parasites of 31 "chub mackerel" Scomber japonicus from the Puerto Chicama, La Libertad, Peru during 2014. 12 parasite species were recorded. Ectoparasites were: Clavellisa scombri and Ceratothoa gaudichaudii. Endoparasites were Prodistomum orientalis, Koellikeria sp. , Maccallumtrema sp. , Didimozoidea gen sp. , Ovarionematobothrium saba, Nematobothrium scombri, Scolex pleuronectis, Anisakis simplex, Contracaecum sp. and Rhadinorhynchus pristis. The three most prevalent parasites and mean abundance were S. pleuronectis, O. saba and N. scombri. The parasites showed an aggregated distribution. The total length of S. japonicus showed no association with the prevalence and abundance of parasitic fauna. Only the prevalence and abundance of O. saba was relatedto host sex. The values of condition factor (k ) and gonadosomatic index (GSI) between parasitized and non-parasitized of n S. japonicus showed differences for O. saba and for S. pleuronectis, respectively. Diversity indices of richness and evenness of the community component and parasitic infracommunity of S japonicus showed high values, being higher in the infracommunity. Differences between the sexes of fish for parasitic infracommunity were observed only to indices of species richness. The richness estimator indicated an expected value of 25% more parasitic species. Comparing the prevalence of parasites of S. japonicus between Port of Callao (2002-2003, Central Coast of Peru) and the Port of Chicama, La Libertad (2014, North Coast of Peru) show significant differences of 61% of the parasites evaluated. Similarity indices of the parasitic fauna between 2002-2003 and 2014 indicated very low values.

The Characteristics of Chronic Heart Failure in Rheumatoid Arthritis

In recent times there is an emerging evidence about the increased risk of cardiovascular disease (CVD) and rheumatic conditions. This review has been focused on the multiple relationships between rheumatoid arthritis (RA) and heart failure (HF) features. Cardiovascular (CV) system involvement is an extra-articular complication of RA and is a major cause of morbidity and mortality. All heart structures may be affected in RA and different clinical manifestations may be seen. HF is a complex clinical syndrome which represents universal end-stage of nearly every form of heart disease and has a poor prognosis. Patients with RA have almost 2-fold higher risk of HF development than non RA-subjects and this high risk is not explained entirely by traditional CV risk factors. RA patients with HF appear to have a more subtle presentation of HF, compared to HF patients without RA, while mortality from HF is significantly higher. In RA HF mostly is manifested by diastolic dysfunction (DD) which is revealed by echocardiography. In general, brain natriuretic peptide (BNP) is an important clinical and prognostic marker of HF, but there are no final data concerning its screening value in RA-subjects. Nevertheless, up to date HF is still being poorly revealed in most RA-patients, especially on early stages of the disease, which leads to HF treatment delay, thus contributing to mortality. These findings emphasize the role and need of further larger studies in this field, which will bring to early identification and treatment of RA-subjects with HF and a decrease in mortality rates.
Footwear-centric body area network with directional UWB antenna

A footwear-centric body area network employing a directional antenna is compared with waist-centric systems using omnidirectional and directional antennas. The effect of body movements on path gain is analysed for two bands at 3.99 and 7.99 GHz. The path gain and data rate results demonstrate that footwear-centric configurations are equivalent to or better than waist-centric body area networks.
