    SGLT2 Inhibitors Therapy in Type 2 Diabetes Mellitus

    Type 2 diabetes mellitus (T2DM) is a chronic progressive disease characterized by chronic hyperglycemia and increased risk of cardiovascular disease (CVD). It results from multiple defects that lead to defective regulation of the blood glucose and requires continuous medical care with multifactorial risk-reduction strategies beyond glycemic control. Multiple groups of drugs have been approved in the past decades that work through different mechanisms. Apart from their limited efficacy in reducing cardiovascular outcome, most of them are neutral, and some may even increase mortality from CVDs such as rosiglitazone. The kidney has an important role in glucose regulation that was only recently targeted for drug development. Sodium-glucose cotransporter 2 inhibitors (SGLT2-I) are a new class of oral antihyperglycemic (OAH) agents that mainly act by preventing the reabsorption of filtered glucose by renal convoluted tubules. By their insulin-independent unique mechanism of action, SGLT2-I result in treating hyperglycemia while avoiding hypoglycemia, promote weight loss, reduce blood pressure, and, more importantly, decrease the risk of major adverse cardiovascular events (MACE). Therefore, SGLT2-I address fundamental aspects of the unmet needs of T2DM management that most of the other OAH failed to resolve. The main side effects of SGLT2-I are slight increase in the incidence of genital mycotic infections (GMI) and euglycemic ketoacidosis (EKA) along with increased risk of lower limb amputations, which has been reported with some but not all agents of this class

    The Schmidt hammer has been used worldwide as a rapid index test to determine rock strength and deformability characterization, this is because it is easy to use, low cost and can be performed in a short time and is non-destructive to samples. There are 6 sampling locations, where the first location was carried out on the outcrop of Jln. Kadrie Oening, the second location was carried out on the outcrop of Jln. Ringroad I, the third location is carried out on the outcrop of Jln. Ringroad II, the fourth location is done on the outcrop of Jln. Hj. Mastuang, the fifth location is done on the outcrop of Jln. Padat Karya, the sixth location is carried out on the outcrop of Jln. Mount Lingai City of Samarinda, East Kalimantan. Research uses quantitative methods, activity plans by making a framework or flowchart. There are many published papers that focus on getting a correlation between Schmidt hammer and unconfined compressive strength. The compressive strength value produced in the Pulaubalang Formation is greater than the compressive strength value in the Balikpapan Formation, where the compressive strength value in the Pulaubalang Formation is 1.187 MPa-1.445 MPa, while the compressive strength value in the Balikpapan Formation is 0.774 MPa-1.032 MPa. The reflected value in the Pulaubalang Formation is greater than the reflected value in the Balikpapan Formation, where the reflected value in the Pulaubalang Formation is 11.167-11.875, while the reflected value in the Balikpapan Formation is 10.417-10.708. There is a positive linear correlation between the compressive strength and the reflected value, where the higher the compressive strength, the higher the rebound value.

    The use of low carbon steel is categorized as one of the supporting materials in industrial and technological developments because it has high ductility and toughness. However, low carbon steel has limitations in terms of corrosion resistance. There are several ways to increase corrosion resistance in steel. One of them is by providing a layer of protection on the steel surface. The steel plating method used is the electrolysis method or electroplating method. This study aims to determine the influence of variations in current, voltage, temperature, and time on the thickness of the coating formed on steel. The steel plating process is carried out by electroplating process where the coating material or anode is Nickel (Ni) with dimensions (60 mm x 30 mm x 0,1 mm). In comparison, the coated object or cathode is SK5 steel with dimensions (50 mm x 20 mm x 0,3 mm). The aim of this study is to investigate the effect of Current, Voltage, Temperature, and Time Variations on the thickness of steel using electroplating processes. Moreover, all factors will be optimised to achieve the best thickness for steel. Consequently, the corrosion resistance of SK5 can be significantly improved by increasing its thickness. The current variations were used 1A, 2A, 3A, and 4A; voltage variations were used 3V, 6V, 9V, and 12V; temperature variations were used 30°C, 40°C, and 50°C; and times variations were used 0 m, 5 m, 10 m, and 20 m. Based on the results of research that has been carried out on all samples, it is concluded that current, voltage, temperature and time affect the thickness of the sample in the electroplating process. The current, voltage, temperature and time values are linearly related to the thickness resulting from the electroplating process

    The 80-kilometer-long Vembanad Lake in Kerala, India, is a Ramsar site. Eutrophication is deteriorating its water quality and threatening its biodiversity. In this study, satellite imageries of Sentinel 2A and Landsat 8 OLI were utilized to determine its water quality. Various data sets of the water quality parameters viz. pH, Electrical conductivity, TSS, TDS, BOD, DO, chloride etc. are analyzed and interpreted. Regression models were developed on the parameters taken up for water quality analysis. The empirical R2 values of the developed models evidenced the accuracy of the developed mdoels. The findings show that remote sensing images are reliable for analyzing surface water quality characteristics. The comparative analysis of the model developed illustrated the effectiveness of using the imaging systems mentioned above for water quality index estimation through remote sensing
