Abstract
An earthquake with a magnitude of 7.4 in Palu City and Donggala District in Central Sulawesi Province on September 28, 2018 has caused a liquefaction disaster. Basically liquefaction can occur in earthquake prone areas, shallow phreatic depth and poorly consolidated soil. This study attempts to examine the relationship between phreatic depth and the probability of liquefaction. The research method is an analog and numerical relation model, by combining the aquifer system model and groundwater geographic information system with landuse patterns in areas affected by liquefaction disasters. This method is described in Spatial and Environmental Analysis, which is supported by the use of satellite imagery and the analysis process with the Arc View Gis 3.3 program. The results showed that there was an influence between rainfall on the spatial distribution of phreatic depth, with the average rainfall in the Palu area being 68.74 mm / month and the depth of phreatic level ranged from medium (2.5 - 7.0 meters from ground level) - shallow (<2.5 meters from ground level). Based on the phreatic depth of the Palu groundwater basin, the chances for liquefaction are in the medium to high zone class.

Abstract
Nitrogen fertilization is needed as a source of nitrogen in the growing plants. Nitrogen in the environment will undergo a transformation in the form of compounds such as nitrate (NO3
−) and nitrite (NO2
−). The transformation from nitrogen to nitrate, nitrite, will have a negative impact on the aquatic environment namely the formation of toxic conditions. The main purpose of this research was to study the residual nitrogen fertilizer in the outlet of paddy irrigation upper Tondano Watershed and to evaluate the residual nitrogen fertilizer in the outlet of paddy irrigation upper Tondano Watershed 5-years period (2015-2019). Water quality sampling was carried out using a composite sampling method at two sample locations in River Panasen, in situ measurement of water temperature parameters, and pH. Analysis of the parameters of nitrate and nitrite was carried out in the laboratory. Data were analyzed using descriptive statistics. The results showed that the concentration nitrate of -0.9330-153 mg/l (according Government standard PP No. 82/2001 nitrate 10 mg/l), and nitrite of 0.001 mg/l-0.52 mg/l exceed PP No. 82/2001 quality standard (0.006 mg/l).

Abstract
Amylases are important enzymes used in a wide range of industries, such as foods, cosmetics, and pharmaceutics. They are classified based on their mechanism of actions in hydrolyzing starch. Amylases can be isolated from soils, plants, fungi, and bacteria, including thermophilic bacteria. The present study was focused on the determination of best temperature and pH of thermophilic amylase produced by thermophilic bacteria, isolated from Pulu Hotspring. As much as 30 isolates showed amylolytic activity in medium enriched with 1% starch. Of 3 isolates with the highest amylolytic index, PL 16 isolates with amylolytic index of 4.04 mm were studied further to find out its activity in amylose degradation. Enzyme activity was measured with the DNS method using maltose as standard. Temperature and pH measurement were varied in the range of 50, 60, 70, 80, 90, 100°C and 5, 6, 7, 8, 9, respectively. Optimum amylase activity was at a temperature of 90°C and pH 8. These results suggested that thermostable crude amylase from Pulu hotspring has a potential future for industrial application.
Learning from the 2018 heatwave in the context of climate change: are high-temperature extremes important for adaptation in Scotland?

Published: January 2020

Abstract
To understand whether high temperatures and temperature extremes are important for climate change adaptation in Scotland, we place the 2018 heatwave in the context of past, present, and future climate, and provide a rapid but comprehensive impact analysis. The observed hottest day (d), 5 d, and 30 d period of 2018 and the 5 d period with the warmest nights had return periods of 5–15 years for 1950–2018. The warmest night and the maximum 30 d average nighttime temperature were more unusual with return periods of >30 years. Anthropogenic climate change since 1850 has made all these high-temperature extremes more likely. Higher risk ratios are found for experiments from the CMIP6-generation global climate model HadGEM3-GA6 compared to those from the very-large ensemble system weather@home. Between them, the best estimates of the risk ratios for daytime extremes range between 1.2–2.4, 1.2–2.3, and 1.4–4.0 for the 1, 5, and 30 d averages. For the corresponding nighttime extremes, the values are higher and the ranges wider (1.5- >50, 1.5–5.5, and 1.6- >50). The short-period nighttime extremes were more likely in 2018 than in 2017, suggesting a contribution from year-to-year climate variability to the risk enhancement of extreme temperatures due to anthropogenic effects. Climate projections suggest further substantial increases in the likelihood of 2018 temperatures between now and 2050, and that towards the end of the century every summer might be as hot as 2018. Major negative impacts occurred, especially on rural sectors, while transport and water infrastructure alleviated most impacts by implementing costly special measures. Overall, Scotland could cope with the impacts of the 2018 heatwave. However, given the likelihood increase of high-temperature extremes, uncertainty about consequences of even higher temperatures and/or repeated heatwaves, and substantial costs of preventing negative impacts, we conclude that despite its cool climate, high-temperature extremes are important to consider for climate change adaptation in Scotland.

Abstract
The goal of the research is to study the effect of Pisum sativum L. seeds treatment before sowing with a complex of microbiological preparation, in comparison with a chemical treatment, on the parameters of plants growth, product quality, and yield, against the background of the system of agriculture without soil tillage. The research was conducted in 2016-2018 in the zone of Central Steppe of Crimea. Trial establishment and researches were carried out in accordance with the generally common methods of field experiments in land husbandry and plant growing. In 2016, the symbiosis of Pisum sativum L plants and the microbial community had a significant impact on the number of beans per plant: the control was 7.6 pieces on 1 plant, and under the influence of complex microbial preparation is 8.6 units per 1 plant (LSD05 – 0,92). The weight of grain from 1 plant was significantly higher by 0.5 g on the variant with inoculation. In 2017 on plant height there is a slight increase in growth when treated with the preparation by 4.4 cm (LSD05 – 5,03). The same thing happens with the number of beans of 8.2 and 8.6 units on the same plant that shows at LSD05 – 1.59, the accuracy increase of this parameter at 0.4 units per plant in the variant with inoculation. Severe weather conditions during the vegetation of Pisum sativum L. in 2018 contributed to the fact that the microbial preparation studied by us practically did not affect the studied indicators of growth and productivity.

Published: January 2020

Abstract
Seed quality is one of the essential prerequisite for high yield formation. Ecological heterogeneity of seeds remains one of the unsolved challenges of seed production as yet. The existence of close relation between seed quality and the conditions of their growing indicates the relevance of the assessment of the ecological nature of seed heterogeneity and becomes the target of the authors’ study. Laboratory and field methods were widely used. The authors investigated different fractions of winter wheat seeds of the Alaya Zarya variety. The seeds were calibrated by width, by the specific weight, and by thickness. The studies have shown that seeds of different fractions differ in their ecological properties. Large seeds calibrated by width, seeds of low specific weight and seeds of shallow thickness were characterized by high responsiveness to vegetation conditions. The seeds of these fractions are recommended to be used in intensive cultivation technologies. The seeds of large fraction calibrated by thickness were characterized by high homeostatic properties and are recommended to be used in organic farming.

Abstract
The article deals with the clinical research of cows during the interlactation period, through reviewing their medical histories and the clinical examination of the animals and their milk glands, trial milking and organoleptic evaluation of the secretion. The secretion was evaluated according to its color, texture, smell and the presence of foreign substances. The best therapeutic dosage of Vetom-3, a medicine based on Bacillus amyloliquefaciens, was determined through the examination of 30 non-milking cows suffering from subclinical mastitis. The probiotic and difumast were injected into the milk glands of the cows diagnosed with subclinical mastitis two weeks prior to the expected calving and in accordance with the examination results received on the 4th day of lactation. After the treatment, the milk was fed to the calves. The evaluation of the change rates of the microflora composition was carried out using calf feces samples. The bacteriological tests of the microflora were carried out using the standard procedures for determining the morphological properties of germ cultures. We ascertained that the use of Vetom-3, a medicine based on Bacillus amyloliquefaciens RNCIM V-10642 (DSM 24614), for the treatment of subclinical mastitis in non-milking cows allows to increase the efficiency of the treatment, as well as receive the milk of high sanitary quality, increase the survival rate of the newborn calves, and prevent dysbacteriosis and dyspepsy incidence in newborn calves.

Authors: Ulez’ko A V , Demidov P V 
Published: January 2020

Abstract
The article concludes that it is necessary to optimize the use and reproduction of productive lands, taking into account the intensity of the natural and anthropogenic load on cultivated lands and the possibilities for their improvement. Improving the stability of cultivated lands is proposed to provide on the basis of a compromise between the economic and environmental orientation of agro-economic systems. The procedure of optimizing the use of productive land, taking into account the assessment of the stability of cultivated lands, is demonstrated. The solution of this problem consists in optimization of the arable land structure using multi-criteria optimization methods in the search for a compromise solution by minimizing the weighted amount of pull-backs from the extreme values of the criteria used (the sum of net or gross income, integral estimates of resistance to anthropogenic load, wind and water erosion).

Published: January 2020

Abstract

Objectives
To review the utilization of prostate-specific antigen (PSA) testing in Winnipeg, a major Canadian city, and to compare PSA testing rates between Winnipeg and Calgary, another major Canadian city of comparable size.

Methods
PSA testing results were reviewed by year and age group. We focused our studies in years 2011 and 2016, for which census demographic data are available.

Results
In Winnipeg, the PSA testing rates (patients with one or two PSA tests divided by the male population) showed a declining trend over years from 2008 to 2017. For almost all age groups, PSA testing rates in 2016 decreased in comparison to those in 2011. For age older than 40 years, the relative percentage decreases were 14% to 20%.
In 2011, Winnipeg PSA testing rates were consistently higher than those in Calgary for all age groups. For age older than 40 years, the relative percentage differences were 36% to 50%.In addition, 41% and 40% of patients in Winnipeg who underwent PSA testing were younger than 50 years or older than 69 years in 2011 and 2016, respectively.

Conclusions
PSA testing utilization may be falling short of optimal rates. There is a need to reinforce the optimal use of clinical recommendations.

Published: January 2020

Abstract

Objectives
Sjögren syndrome (SS) is considered as a major etiologic factor for primary salivary gland lymphoma (SGL). However, the percentage of SGL that is caused by SS (and thus the real impact of SS on SGL epidemiology) is unclear. We aimed to assess the prevalence of SS in patients with SGL through a systematic review and meta-analysis.

Methods
Electronic databases were searched for studies assessing the presence of SS in patients with SGL. Pooled prevalence of SS in SGL was calculated, with a subgroup analysis based on histotype (mucosa-associated lymphoid tissue [MALT] vs non-MALT).

Results
Sixteen studies with 665 SGLs were included. Pooled prevalence of SS in SGL was 18.2%, with high heterogeneity among studies. In MALT SGL, the prevalence of SS was 29.5%, with moderate heterogeneity. In non-MALT SGL, the prevalence of SS was 0%, with null heterogeneity.

Conclusions
SS seems to be responsible for a significant but minor portion of SGLs. SS appears involved in MALT-type SGL but not in other histotypes.

Abstract
We aimed to examine the retention of Hispanics/Latinos participating in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), a prospective cohort study of 16,415 adults in 4 US cities who were enrolled between 2008 and 2011. We summarized retention strategies and examined contact, response, and participation rates over 5 years of annual follow-up interviews. We then evaluated motivations for participation and satisfaction with retention efforts among participants who completed a second in-person interview approximately 6 years after their baseline interview. Finally, we conducted logistic regression analyses estimating associations of demographic, health, and interview characteristics at study visit 1 (baseline) with participation, high motivation, and high satisfaction at visit 2. Across 5 years, the HCHS/SOL maintained contact, response, and participation rates over 80%. The most difficult Hispanic/Latino populations to retain included young, single, US-born males with less than a high school education. At visit 2, we found high rates of motivation and satisfaction. HCHS/SOL participants primarily sought to help their community and learn more about their health. High rates of retention of Hispanics/Latinos can be facilitated through the employment of bilingual/bicultural staff and the development of culturally tailored retention materials.
