Pembudidaya di Kota Tasikmalaya tergabung dalam kelompok pembudidaya yang setiap kelompok biasanya terdiri atas 15 orang anggota. Dengan adanya pandemi Covid-19, pembudidaya ikan sebagian tidak melanjutkan usaha budidaya. Penelitian ini bertujuan untuk menguraikan secara detail derajat keberdayaan pembudidaya ikan di Kota Tasikmalaya yang ditinjau dari aspek internal dan eksternal pembudidaya. Penelitian ini dilakukan di Kota Tasikmalaya pada Oktober-Desember 2021. Desain penelitian berupa survei dengan kuesioner terstruktur dengan skala pengukuran ordinal. Keseluruhan responden adalah 81 orang pembudidaya yang masing-masing mewakili 1 kelompok perikanan. Terdapat empat derajat keberdayaan yang diukur, yakni tingkat kesadaran dan keinginan berubah, kemampuan meningkatkan kapasitas untuk memperoleh akses, kemampuan menghadapi hambatan, kemampuan kerja sama dan solidaritas.

Alquran yang sudah ada sejak priode Nabi Muhammad hingga abad 20 yang mana fenomena kehadiranyya ini banyak memunculkan bagaimana Islam menjawab berbagai perkembangan sesuai ruang dan waktunya. Penulis melihat dalam buku Living Religions: Chapter 10 tersebut ada dua poin penting untuk ditampakkan ke permukaan. Pertama, banyak muslim sedikit mengetahui kehidupan Arab pra-Islam. Orang bisa mengamatinya dari betapa berkembangnya praktik Islam artinya keyakinan muslim itu dari agama Nabi Ibrahim sekaligus mengikuti ajaran hanif. Kedua, alasan kenapa yang dipilih living Islam terletak pada ketika seorang muslim membaca Alquran tetapi tidak memahami kandungannya maka keyakinannya disangsikan. Peneliti melihat jika dalam memahami alquran tanpa memahami kandungannya, maka hal tersebut...

We believe AI will continue its present path and ultimately become a mature and effective tool for the healthcare sector. Besides this AI-based systems raise concerns regarding data security and privacy. Because health records are important and vulnerable, hackers often target them during data breaches. The absence of standard guidelines for the moral use of AI and ML in healthcare has only served to worsen the situation. There is debate about how far artificial intelligence (AI) may be utilized ethically in healthcare settings since there are no universal guidelines for its use. Therefore, maintaining the confidentiality of medical records is crucial. This study enlightens the possible drawbacks of AI in the implementation of healthcare sector and their solutions to overcome these situations.

The aim of this study was to determine the various etiological factors of traumatic perforation of tympanic membrane and their clinical presentation, observation and the treatment modalities in tertiary care centre. This prospective study was performed on 156 cases of traumatic tympanic membrane perforation in the Department of ENT and Head & Neck Surgery, Government medical college Srinagar from JULY 2015 to JULY 2017 from various causes. The data collected include the bio-data, the symptoms, nature of injury, the clinical ndings, hearing loss and the treatment outcome. Findings: 156 ears were analyzed, Age ranged from 3 years to 65 yrs. The group consisted of 75 (48%) male and 81(52%) female patients. Slaps (66%) was the most common cause, followed by road trafc accidents and solid object injuries. Conclusion: In our study majority of the traumatic perforation heal spontaneously w...

Diverse biotic and abiotic stresses seriously affect the wheat growth, which results in low yield. Plant tissue culture is a technique used for in vitro regeneration of plants. Standardization for callus induction and regeneration is of vital importance to deploy the transformation aim full in wheat but Poor tissue culture performance, which is another obstacle in transformation of wheat genotypes. Therefore, to address this obstacle this review depicts various works of various scientist. They conducted many researches to evaluate response of different wheat genotypes to callus induction and plant regeneration. Therefore, the information generated through this review could be utilized to overcome poor tissue culture performance in wheat.

S. constellatus, a gram positive, non-sporing, non-motile, catalase negative cocci, is the normal flora of the oropharyngeal, gastrointestinal and urogenital tract. It is not a commonly encountered pathogen but has a propensity to form abscesses and cause bacteremia in the immunocompromised patient. Here, we report a 78-year-old man with sepsis due to Streptococcus constellatus liver abscess. The patient had a history of hypertension, stroke, benign prostatic hyperplasia, vascular dementia and myocardial infarction status post coronary artery bypass grafting. There has been no particular link between any of these conditions to S. constellatus. However, immunocompromised status predisposes to fulminant infection and formation of abscesses. The patient was febrile with a temperature of 99.1°F, blood pressure of 143/73 mmHg and the heart rate (HR) of 98. Labs revealed a leukocytosis of 16.90 K/uL, hemoglobin 11.8 g/dL, hematocrit 35.8%, total bilirubin 1.7 mg/dL, direct bilirubin 1.0 mg/dL, aspartate aminotransferase (AST) 44 IU/L, alanine aminotransferase (ALT) 28 IU/L, alkaline phosphatase (ALKP) 176 IU/L and lactate dehydrogenase (LDH) was 290 IU/L. He was started on intravenous Maxipime and Unasyn which was switched to Rocephin and Clindamycin based on the Infectious disease recommendations. Metronidazole was also started and the serologies were sent for Entamoeba histolytica. Computerized tomography (CT) scan showed an abscess in the right lobe of the liver which was finally drained using an interventional radiology (IR)-guided approach. The cultures from the fluid and blood yielded S. constellatus and thus Metronidazole was discontinued. The patient improved after a few days and the drainage catheter was pulled out and the patient discharged in stable condition.

The patient had a temperature of 100°F, severe jaundice, and scleral icterus. Laboratory workup showed severe hyperbilirubinemia and elevated serum creatinine, and the rest of the serum chemistry was unremarkable. The ultrasound and computed tomography (CT) of the abdomen was normal. The patient had a recent history of travel to an endemic area for Lyme disease. After an extensive workup, all other possible etiologies had been ruled out, and the patient was started on empirical doxycycline by considering the patient's recent history of travel. Serum serologic test confirmed Lyme disease. His bilirubin and creatinine improved gradually. His fever subsided in three days, and he was discharged with outpatient follow-up. Although hyperbilirubinemia is rare in Lyme disease, it should be considered as a differential diagnosis in patients with severe jaundice and a recent history of travel.

This study encompasses in-vitro pathogenicity of two strains of Beauveria bassiana (BB-72 and BB-252) and one strain of Lecanicillium lecanii (V-4) against green peach aphid (M. persicae). Using a leaf-dip method, three different bioassays were conducted comprised of filtrates and conidial concentrations of BB-72, BB-252 and V-4 fungal strains and their binary combinations. Infiltrate bioassays, 2 mL fungal filtrate of each strain was used. In conidial bioassays, three different concentrations (i.e., 1 × 106, 1 × 107 and 1 × 108 conidia mL−1) of each fungal strain were used, while in binary combination bioassays, LC50 and LC33 of these fungal strains were evaluated. According to the results, maximum pathogenicity against test aphids was observed at 10th day of all treatments. Both strains of B. bassiana (BB-72 and BB-252) exhibit...

Here we use the Eretmocerus warrae-greenhouse whitefly system to investigate how fluctuating density of the parasitoid and its host affects three key parasitoid fitness parameters: host searching, host feeding and parasitization, providing critical knowledge for evaluation and development of whitefly biological control programs. This is the first such study in a parasitoid-whitefly system. Models used and developed here show that (1) both host feeding and parasitism fit a Type II functional response; (2) overall parasitoid-caused whitefly mortality significantly increases with growing density of both organisms and the parasitoid density has significantly more positive effect; (3) with the pro-synovigenic nature, E. warrae allocate significantly more resources to parasitization than to host feeding activity in low whitefly density and high parasitoid density, and (4) low mu...
