The Government of Ghana recognizes the importance of wetlands as a habitat for wildlife, in the maintenance of the water table, mitigation of flood conditions, and water purification. Wetlands resources are also known to be of socio-economic importance and have been harvested for construction poles, fuel-wood, timber for furniture, and craftwork

The European Association of Urology currently recommends partial nephrectomy as the preferred management for localised cT1 renal tumours, irrespective of surgical approach. With the advent of robotic assisted partial nephrectomy, there is growing evidence that warm ischaemia time may be reduced compared to the traditional laparoscopic approach.

The Rapid generation rate of solid waste due to increasing population and industrialization leads to open dumping of solid waste. This causes serious environmental risk of groundwater contamination due to landfill leachate, that consists of heavy metals and impurities.

Carica papaya x vasconcelleacauliflora and intergeneric F1 hybrids of these species were screened for resistance to severely infected papaya ringspot virus isolates of papaya ringspot virus. Artificial screening for papaya ringspot virus was carried out 27 days after sap inoculation. Out of twenty-nine F1 hybrid plants of CO 7 x Vasconcelleacauliflora, only six plants were found free from PRSV symptoms. Similarly, out of fifty-five F1 hybrid plants of PusaNanha x Vasconcelleacaulifloraonly twenty-three were found free from the symptoms and seventy plants out of 335 plants of CP50 x Vasconcelleacauliflora were found free from PRSV symptoms. The resistance of the hybrids and parents and their hybrids viz, CO 7 x Vasconcelleacauliflora, PusaNanha x Vasconcelleacauliflora and CP50 x Vasconcelleacauliflora were subjected to DAS ELISA test. Molecular marker viz, ISSR markers were used to check and verify the hybridity. ISSR markers showed confirmity on three hybrid progenies viz, CO7V3, CO7V5 and CO7V6 from CO 7 xVasconcelleacauliflora.

Necrotizing Sialometaplasia (NSM) is a rare, benign, self-limiting, inflammatory disease of mostly minor salivary gland origin. NSM can resemble a malignant lesion in its early disease course, both clinically and pathologically. Bilateral involvement of the hard and soft palate by the lesion is a rare occurrence. NSM was first described as a reactive inflammatory process. Since then, over 200 cases have been reported and has been added to the WHO classification of salivary gland tumours under the tumour-like lesions. Here, we report a case of a 30-year-old male with bilateral NSM of both the hard and soft palate, on a background history of prurigo nodularis. The patient was initially referred to an Oral and Maxillofacial Department by his general practitioner for a palatal ulcer, concerning for oral malignancy. The ulcer was painless with a well-demarcated border and necrotic base. Subsequent biopsy and histological examination confirmed necrotizing sialometaplasia with healing occurring within 5 weeks.

Background: Morocco is a low endemic country of HIV/AIDS that achieved the goal of the second and third 90-90-90 targets in 2019 while still 78% of people living with HIV know their HIV status. The aim of this study was to analyze time trends of HIV/AIDS reported cases during the last 33 years taking into consideration the implementation of voluntary HIV counseling and testing (HCT) services in primary health care facilities. Methodology: This was a time series of HIV/AIDS reported cases at national level between 1986 and 2019. Variable collected for each year were HIV/AIDS reported per 100000 H, age category, gender, origin, CD4 count and route of transmission. Trend of HIV/AIDS reported cases was assessed by Joinpoint Regression Analysis. Annual percentage changes (APCs) were estimated to identify the years (joinpoint) when significant changes occurred in the trend. We therefore examined trends in HIV/AIDS reported cases according to epidemiological variables. Results: Cumulative HIV/AIDS reported cases during the study period was of 17 000. Joinpoint regression showed an increase in HIV/AIDS reported cases between 1986 and 2019. The APC for the period 1986-2012 was of 13.4 (95% CI: 12.0 to 14.8, p

Cutting fluids are an inherent part of the modern manufacturing system. In the vegetable oil based cutting fluids, the base fluids should be some vegetable oil. In general, vegetable oil is highly attractive substitutes for petroleum based oils because they are environmentally friendly, renewable, less toxic and readily biodegradable. In this review paper, the author investigates some of the published research papers on the application of vegetable oil based machining fluids (including Nano-fluids) in the different machining processes like turning, milling, grinding and drilling. Besides that, this study also summarize the effect of the different biodegradable oil based machining fluids on the performance factors such as surface integrity, machining force, tool wear, power consumption, and temperature produced during the machining process. It has been reported in various literature that using vegetable oil based Nano machining fluid results high surface features, reduced tool wear, cutting force, power consumption and lower temperature rise in the machining process due to better lubrication and cooling properties.
