Analysis and Interpretation of In-Phase Component of VLF-EM Data using Hilbert Transform and the Amplitude of Analytical Signal

An interpretation of in-phase anomaly of very low frequency electromagnetic (VLF-EM) data was carried out using the analysis of the Hilbert transform of the in-phase component and the amplitude of its analytic signal. The analysis was used to delineate the source and depth to the top of a subsurface conductive body. The amplitude of the analytical signal of the data was observed to mimic the conventional Fraser-filtered operation and was used to locate the exact location of the anomalous body. The in-phase component with the Hilbert transform yields an approximate depth to the top of the conductor which agree with the result of the vertical electrical sounding conducted at the vicinity of the anomalous body.

TB116: Integrated Systems for Managing Potatoes in the Northeast

This technical bulletin presents the results of a research project developed to determine the feasibility of using an integrated pest management (IPM) system to improve economic and environmental benefits for the Northeast region. Research was conducted to develop and evaluate IPM techniques. These techniques were then tested, improved, and implemented in pilot programs on commercial potato farms in Suffolk County and Steuben County, New York, and Aroostook County, Maine.https://digitalcommons.library.umaine.edu/aes_techbulletin/1076/thumbnail.jp

The influence of emotional reaction on help seeking by victims of school bullying

Research has started to focus on how victims of school bullying cope, but there is still very little understanding if why pupils cope in one way and not another. This paper aimed to examine the effects of gender, school-stage, frequency of victimization and different emotions (anger, vengeance, self-pity, indifference, and helplessness) upon the choice of social support that children report using. Questionnaires were completed by 6282 Maltese schoolchildren aged between 9 and 14 years old. Analyses revealed that specific patterns of emotion and victimization predict whether pupils report using certain sources of social support. Results are discussed in relation to their relevance for possible intervention, future research needs and implications for the theoretical framework used

Finfish resources in the north eastern region in the Indian EEZ

Bottom trawling conducted in 53 stations lat. 16°00'N -20°30'N; long. 81°30'E - 87°15'E revealed a production range of 3 - 15000 kg/haul with a mean of 581 kg/haul; the average catch in the region was 567.3 kg/hr. The dominant finfish in the surveyed area were Indian drift fish (36.4%), carangids (22.5%), catfishes (7.1%), bull's eye (6.9%), goat fishes (3.9%), nemipterids (3.3%) etc. The bathymetric zones above 200 m and 51-100 m were found to be highly productive with average catch rate of 1615 and 830 kg/hr respectively. In the surveyed region the highest production rate was at lat. 19°N (1384 kg/hr)

The Present status of our knowledge on the lesser sardines of Indian waters

The results of research carried out at Waltair, Mandapam. Tuticorin and Vizhinjam and another centres on the lesser sardines over the past up till 1978 are reviewed in detail. In the twentyyear period from 1958 to 1978 there was an increasing trend of production of these fishes along the different coasts of India, the average annual landings nearly doubling from 36,000 t in 1958-67 to 70,000 t in 1968-78. The bulk of the catches came from Tamil Nadu, including Pondicherry, (32.6%), Kerala (32.2%) and Andhra Pradesh (26.5%)- Fishing was mostly by the labour-intensive traditional methods in close-shore waters, better catches coming from 30-55 m depths. Shore seines, boat seines and gill nets were the principal gears employed in the fishery though gill nets were the most effective

Stress appraisal, coping, and work engagement among police recruits: an exploratory study.

This study investigated the influence of stress appraisal and coping on work engagement levels (Absorption, Vigour, and Dedication) of police recruits. Participants were 387 men, ages 20 to 33 yr. (M = 24.1, SD = 2.4), in their last month of academy training before becoming police officers. Partially in support of predictions, work engagement was associated with Stressor control perceived, but not Stress intensity experienced over a self-selected stressor. Although the three dimensions of work engagement were explained by Stressor control and coping, Absorption was the dimension better explained by these variables. Police recruits reporting higher Absorption, Vigour, and Dedication reported using more Active coping and less Behavioural disengagement. Results showed that stress appraisal and coping are important variables influencing work engagement among police recruits. Findings suggested that future applied interventions fostering work engagement among police recruits should reinforce perceptions of control over a stressor as well as Active coping strategies

Interaction of the solar wind with Venus

Two topics related to the interaction of the solar wind with Venus are considered. First, a short review of the experimental evidence with particular attention to plasma measurements carried out on Mariner-5 and Mariner-10 is given. Secondly, the results of some recent theoretical work on the interaction of the solar wind with the ionosphere of Venus are summarized

Pharmacodynamic and cytotoxicity effects of Syzygium cordatum {S Ncik, 48 (UZ)} fruit-pulp extract in gastrointestinal tract infections

Purpose: To evaluate the pharmacodynamic effect and cytotoxicity of S. cordatum pulp extract in the treatment of gastrointestinal tract infections.Methods: The air-dried fruit pulps were ground, extracted with 100 % methanol and screened for phytochemicals. Serial microdilution method was used to determine the antibacterial activity of the extract against Bacillus cereus (ATCC 10102), Staphylococcus aureus (ATCC 25925), Enterococcus hirae (ATCC 8043), Escherichia coli (ATCC 25922), Salmonella typhimurium (ATCC 700030), Klebsiella pneumonia (ATCC 4352), Pseudomonas aeruginosa (ATCC 7700), Vibrio fluvialis (AL 019) and Vibrio vulnificus (AL 042). The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay was used to assess the cytotoxicity of the extract. Antidiarrheal and antimotility activities were evaluated using castor oil-induced diarrhoea model in rats.Results: The extract revealed the presence of alkaloids, cardiac glycosides, flavonoids, saponins and terpenoids. Total phenolic content was 16.4 ± 1.8 μg/mg. The extract exhibited antibacterial activity with minimum inhibitory concentration (MIC) of as low as 3.13 mg/ml against B. cereus (ATCC 10102), S. aureus (ATCC 25925), E. hirae (ATCC 8043), P. aeruginosa (ATCC 7700) and K. pneumonia (ATCC 4352). Median inhibitory concentration (IC50) of 92 μg/ml and therapeutic index of 0.1 - 0.3 were exerted by the extract. In vivo antidiarrheal activity was 49 % at extract dose of 400 mg/kg, which was much higher than that of the control (0 %).Conclusion: The fruit-pulp extract of Syzyhium cordatum has both antibacterial, antimotility and antidiarrheal activities, and may therefore be clinically safe for use at low concentrations as an antidiarrheal agent.Keywords: Syzyhium cordatum, Antibacterial, Antidiarrheal, Antimotility, Cytotoxicit
