CylE and mig as virulence genes of streptococci isolated from mastitis in cows and buffaloes in Egypt

Objective: A study is carried out to investigate the prevalence of mastitis caused by Streptococcus agalactiae and Streptococcus dysgalactiae in cows and buffaloes, their antibiotics susceptibility, minimum inhibitory concentrations (MIC), and molecular investigation of some virulence genes. Samples: A total of 288 milk samples gathered from 72 mastitic animals from households and small-scale dairy farms in Egypt, were analyzed. Procedures: Isolation and identification of S. agalactiae and S. dysgalactiae were performed using conventional techniques. The identified isolates were examined for antimicrobial resistance by disk diffusion assay, MIC by broth microdilution method as well as virulence genes by PCR. Results: Forty-five out of 72 animals show the clinical signs of mastitis. Microbiological evaluation of 288 mastitis milk samples displayed 190 (65.72%) streptococci strains composing of 60% S. agalactiae and 40% S. dysgalactiae strains. The antibiotic susceptibility tests revealed that S. agalactiae strains were resistant to trimethoprim (100%), followed by tetracycline and minocycline (37.7%). Moreover, S. dysgalactiae strains were highly resistant to lincomycin, tetracycline (87.52 each), followed by trimethoprim (81.6) and minocycline (75%). Additionally, the highest MIC with the widest range (1 to ≥128 μg/mL) were observed to trimethoprim for S. agalactiae and to erythromycin and lincomycin for S. dysgalactiae. In contrast, the lowest MIC was detected to penicillin, amoxicillin, cefquinome, and erythromycin for S. agalactiae and to penicillin, amoxicillin, cephapirin, cefquinome, and rifaximin for S. dysgalactiae. The cylE gene is displayed in 6 (60%) S. agalactiae strains, whereas the mig gene is found in 4 (40%) S. dysgalactiae strains.
Study on a High Accuracy Measuring Method for Root Diameter of Sugar Beets

To estimate the optimum harvest time and to predict the crop yield with meteorological data, a measurement system for the growth of a sugar beet accurately and nondestructively was attempted to develop. The system which measures the root diameter with transducer in the soil is designed and made on an experimental basis. Measurement accuracy with two transducers was higher than with one for one sugar beet. The influence of the external disturbances was little to the system. Shrinkage and expansion in root growth and the blunting of root swelling at the end of growth were measured. Accumulation and analysis of measured data have possibility to estimate the optimum harvest time and to predict the crop yield accurately.

The association between Helicobacter pylori eradication in peptic ulcer patients and gastric cancer? Investigation in an East-Asian population

H. pylori is Gram-negative, microaerophilic, and motile bacteria which colonized in human stomach of nearly 50% of world population; there are several evidence for chronic colonization with H. pylori that significantly increased the risk of gastric cancer development (15). Eradication of H. pylori infection can have reduced the risk of gastric cancer as well as reduction of H. pylori in young population as reservoir of infection (5,10). According to literatures, the mother to child transmission is predominant rout of H. pylori transmission in Japanese population; therefore, eradication of H. pylori infection can be considered as appropriated strategy for reducing both of gastric cancer as well as H. pylori infection burden (16). There are several literatures in relation to efficacy of H. pylori eradication for prevention of gastric cancer development in asymptomatic carrier and patients with endoscopic resections (7,8); however, we evaluated the efficacy of H. pylori eradication in reduction of gastric cancer in patients with history of peptic ulcer. We are suggested that H. pylori infection should be eradicated in peptic ulcer patients in order to reducing the risk of develop to gastric cancer.
Synthesis and Characterization of Highly Crystalline Zinc Phosphide Nanoparticles

Nanoscale alpha zinc phosphide (α-Zn3P2) particles are a class of promising opto-electronic materials which have attracted worldwide attention. The synthetic protocols pertaining to α-Zn3P2 nanoparticles have been largely based on the use of costly, pyrophoric and toxic phosphines precursors. We reported here the results of our investigation into the viability of fabricating crystalline α-Zn3P2 nanoparticles using phosphorous pentabromide (PBr5) as precursor via an air-stable solid hydrogen phosphide (PH)x intermediate. HRTEM analysis revealed the best sample as spherical crystalline α-Zn3P2 nanoparticles with diameter found to be 5.8±2.1 nm. These particles exhibited photoluminescence centered at 470 nm (2.6 eV), blue-shifted by 1.2 eV from the 1.4 eV of bulk α-Zn3P2.
Sales-Orientation and Customer-Orientation on Performance of Direct Sales Executives of Fidelity Bank, Ghana

Data were analysed using descriptive statistics, Kendall’s coefficient of concordance, cross tabulation and chi-squared test of independence. The result showed a strong association between prior sales experience and employment status. DSEs customer orientation was influenced by customer information while the sales orientation was on convincing customers to buy. The customer-oriented culture was based on reliable market and customer information. DSEs sales performance were influenced by complete knowledge of the bank’s products and services, listening skills and empathy. The study suggests that Fidelity Bank must sensitize its DSEs on the bank philosophy on its customer orientation culture. This study appears to be the first of its kind to explore the connection between sales orientation and customer orientation on performance in the Banking Industry in Ghana, thus providing empirical evidence for academics and practitioners.
Changing Low Flow and Streamflow Drought Seasonality in Central European Headwaters

In the context of the ongoing climate warming in Europe, the seasonality and magnitudes of low flows and streamflow droughts are expected to change in the future. Increasing temperature and evaporation rates, stagnating precipitation amounts and decreasing snow cover will probably further intensify the summer streamflow deficits. This study analyzed the long-term variability and seasonality of low flows and streamflow droughts in fifteen headwater catchments of three regions within Central Europe. To quantify the changes in the low flow regime of selected catchments during the 1968–2019 period, we applied the R package lfstat for computing the seasonality ratio (SR), the seasonality index (SI), mean annual minima, as well as for the detection of streamflow drought events along with deficit volumes. Trend analysis of summer minimum discharges was performed using the Mann–Kendall test. Our results showed a substantial increase in the proportion of summer low flows during the analyzed period, accompanied with an apparent shift in the average date of low flow occurrence towards the start of the year. The most pronounced seasonality shifts were found predominantly in catchments with the mean altitude 800–1000 m.a.s.l. in all study regions. In contrast, the regime of low flows in catchments with terrain above 1000 m.a.s.l. remained nearly stable throughout the 1968–2019 period. Moreover, the analysis of mean summer minimum discharges indicated a much-diversified pattern in behavior of long-term trends than it might have been expected. The findings of this study may help identify the potentially most vulnerable near-natural headwater catchments facing worsening summer water scarcity.
The Use of a Heat Pump in a Ventilation Unit as an Economical and Ecological Source of Heat for the Ventilation System of an Indoor Swimming Pool Facility

Air handling units are usually used to maintain the thermal and humidity parameters in indoor swimming pools that are used for lap swimming and recreation. Their use throughout the year consumes much more energy than, for example, air conditioning in residential or office buildings. Their considerable energy consumption is due to the need for their continuous operation to remove moisture gains from the evaporation of water and to heat the air and cover the heat losses of the pool. It is possible to design ventilation devices in such a way that the operating costs will be reduced, and the environmental impact will be significantly reduced. In this article, six different ventilation units in which different heat sources are used to heat the ventilation air have been evaluated; the selection of which was based on the most commonly used solutions. The results of the analysis are aimed to show which of the available heat sources is the most advantageous in terms of global and operating costs, and in terms of low CO2 emissions. Indicators of both the final and primary energy consumption, as well as the operating and global costs, were determined. The recommended solution that was chosen was the one that had both the lowest cost index (18–20% lower than most ecological sources) and the low primary energy index (8–13% higher than most ecological sources). The results showed that a heat pump in the ventilation unit proved to be the most beneficial solution. Unfortunately, this solution is rarely used due to its high investment costs (20% higher). However, the results have shown that the investment cost of using an advanced air handling unit will be recouped in only two to three years. Also, the global cost for units with a heat pump proved to be the lowest, despite high investment cost.
Long-Term Prognosis of Peri-Implantitis Treatment: A Systematic Review of Prospective Trials with More Than 3 Years of Follow-Up

A multitude of clinical trials have tested therapeutic approaches to treat peri-implantitis but there is still no consensus on what treatment modality leads to the most favorable clinical improvement and reduced implant loss. Therefore, the present systematic review reported on the long-term clinical and radiological outcomes after treatment of peri-implantitis with different surgical approaches. A PICO question was defined; manual and electronic searches were completed to screen for human prospective studies with at least 3 years of follow-up after surgical treatment of peri-implantitis. Analyses were performed using a random-effect model. Thirteen trials reported on 706 implants and 399 patients. Open flap, resective and reconstructive approaches led to a probing depth reduction of 2.23, 2.25 and 3.78 mm with a survival rate of 84%, 90% and 95%, respectively. Reconstructive treatments were followed by an average of 2.34 mm of radiographic bone gain, flap had negligible bone changes (0.11 mm) and resective approaches resulted in a mean bone loss of 0.5 mm. Large heterogeneity existed among studies for diagnostic criteria and decontamination modalities. Within the existing limitations, regenerative approaches for the treatment of peri-implantitis lead to advantageous long-term improvement of peri-implant tissues and higher implant survival rate.

Molecular Dynamics Simulations about Adsorption and Displacement of Methane in Carbon Nanochannels

Adsorption and displacement are two important issues in the exploitation of shale gas. In this study, molecular dynamics (MD) simulations are employed to study the mechanisms about adsorption and displacement of methane in carbon nanochannels. Here, the nanochannel is modeled as the slit pore. Because of the attractive potentials of the walls, more methane molecules can be stored in the slit pore compared to the bulk phase, and part of them are in the adsorption state. As the width of slit pore increases, the structure of adsorbed methane transforms from single adsorption layer to four adsorption layers. Moreover, it is found that the small slit pore fills up quicker and can store more methane than the larger one under relatively low pressure due to its deeper potential well. To displace the adsorbed methane and enhance the gas recovery, injection gases such as carbon dioxide and nitrogen are simulated and investigated. The displacement mechanisms of the two gases are found to be different: carbon dioxide.
Assessment of Climate Change Impacts on River Flow Regimes in the Upstream of Awash Basin, Ethiopia: Based on IPCC Fifth Assessment Report (AR5) Climate Change Scenarios

The Awash River Basin is the most irrigated area in Ethiopia, which is facing critical water resources problems. The main objective of this study was to assess the impacts of climate change on river flows in the upper Awash Subbasin, Ethiopia, using the soil and water assessment tool (SWAT) hydrological model. The ensemble of two global climate models (CSIRO-Mk3-6-0 and MIROC-ESM-CHEM with RCP4.5 and RCP8.5) for climate data projections (the 2020s, 2050s, and 2080s) and historical climate data from 1981–2010 was considered. Bias-corrections were made for both the GCM data. SWAT model was calibrated and validated to simulate future hydrologic variables in response to changes in rainfall and temperature. The results showed that the projected climate change scenarios were an increase in rainfall for the period of the 2020s but reduced for the periods of 2050s and 2080s. The annual mean temperature increases, ranging from 0.5 to 0.9 °C under RCP4.5 and 0.6 to 1.2 °C under RCP8.5 for all time slices. In the 2020s, annual mean rainfall increases by 5.77% under RCP4.5 and 7.80% under RCP8.5, while in 2050s and 2080s time slices, rainfall decrements range from 3.31 to 9.87% under RCP4.5 and 6.80 to 16.22% under RCP8.5. The change in rainfall and temperature probably leads to increases in the annual streamflow by 5.79% for RCP4.5 and 7.20% for RCP8.5 in the 2020s, whereas decreases by 10.39% and 11.45% under RCP4.5; and 10.79% and −12.38% for RCP8.5 in 2050s and 2080s, respectively. Similarly, in the 2020s, an increment of annual runoff was 10.73% for RCP4.5 and 12.08% for RCP8.5. Runoff reduces by 12.03% and 4.12% under RCP4.5; and 12.65% and 5.31% under RCP8.5 in the 2050s and the 2080s, respectively. Overall, the results revealed that changes in rainfall and temperature would have significant impacts on the streamflow and surface runoff, causing a possible reduction in the total water availability in the subbasin. This study provides useful information for future water resource planning and management in the face of climate change in the upper Awash River basin.
