Serangan Penggerek Padi Putih Dan Penampilan Agronomis Galur-galur Padi Sawah Irigasi
The white rice borer (Tryporyza innotata Walker) attack and agronomic traits of low land paddy lines. Field trial evaluation on 10 lines/varieties to observe the white rice borer (Tryporyza innotata Walker) attack and agronomic traits was conducted at AIAT Lampung on wet season of 2004. The trial was conducted in endemic white rice borer area in Rejo Basuki, Seputih Raman District, Central Lampung. Experiment was arranged in a Randomized Block Design with four replications. Variables observed were precentage of plants attack, yield at 14% moisture contents, period of flowering, number of grain, total grain per panicle, number of stem per hill, plants height, maturity, 100 seed weight and vegetative and generative vigors. Results indicated that among the lines/varieties there were significant different on white rice borer incidence. The BP-360e-Mr-79-Pn-2 line showed low incidence of white rice borer, higher number of stem per hill height plant 104.9 cm, total grain per panicle of 5200 kg, 1000 grain weight and good on vegetative and better generative vigor. But no different seed is compared with other lines, the BP-360e-Mr-79-Pn-2 lines showed 49. 9 empty grain per panicle and 80% mature at 105 days harvested
CT-FC: more Comprehensive Traversal Focused Crawler
In today’s world, people depend more on the WWW information, including professionals who have to analyze the data according their domain to maintain and improve their business. A data analysis would require information that is comprehensive and relevant to their domain. Focused crawler as a topical based Web indexer agent is used to meet this application’s information need. In order to increase the precision, focused crawler face the problem of low recall. The study on WWW hyperlink structure characteristics indicates that many Web documents are not strong connected but through co-citation & co-reference. Conventional focused crawler that uses forward crawling strategy could not visit the documents in these characteristics. This study proposes a more comprehensive traversal framework. As a proof, CT-FC (a focused crawler with the new traversal framework) ran on DMOZ data that is representative to WWW characteristics. The results show that this strategy can increase the recall significantly
Environmental Conditions and COVID-19 Incident
COVID-19 is a new infectious disease caused by the SARS-CoV-2 virus and was designated as a pandemic since March 12, 2020, because there are a lot of case in several countries. On February 1, 2021, the total number of COVID-19 cases reached 103 million in the world, and in Indonesia it reached 1.09 million. Many factors influence the transmission and death of COVID-19, for example environmental conditions. This study aims to provide an overview of environmental conditions that can be a factor for transmission and death due to COVID-19. The method in this research is literature review, which is a literature review with secondary data obtained through research journals which are then synthesized and obtained 23 articles as a reference for preparing literature reviews. COVID-19 and environmental degradation have decreased air, water, noise and marine pollution due to the lockdown, but there has been an increase in the volume of hazardous and toxic waste from COVID-19 patients. Then from air pollution, the results of decreases in CO, NO2, and PM10 during lockdown. Meanwhile, for climatology and meteorology, the result is that every 1oC increase in temperature from the average temperature can reduce daily cases of COVID-19 by 36% and 57% when the average humidity is at 67% and 85.5%. Likewis,e humidity each 1oC increase relatively reduces daily cases of COVID-19 by 11% to 22% with a temperature range of 5.04oC to 8.2oC. The conclusion of this research is that the environmental conditions during a pandemic had their own polemic. However, several pollutants such as CO, NO2, O3, PM2,5, and PM10 is closely related to the spread of COVID-19. This literature review can provide recommendations for an overall global government demonstration policy in the prevention and control of environmental pollution and recycling of medical waste
Diabetes Alters Intracellular Calcium Transients in Cardiac Endothelial Cells
Diabetic cardiomyopathy (DCM) is a diabetic complication, which results in myocardial dysfunction independent of other etiological factors. Abnormal intracellular calcium ([Ca2+]i) homeostasis has been implicated in DCM and may precede clinical manifestation. Studies in cardiomyocytes have shown that diabetes results in impaired [Ca2+]i homeostasis due to altered sarcoplasmic reticulum Ca2+ ATPase (SERCA) and sodium-calcium exchanger (NCX) activity. Importantly, altered calcium homeostasis may also be involved in diabetes-associated endothelial dysfunction, including impaired endothelium-dependent relaxation and a diminished capacity to generate nitric oxide (NO), elevated cell adhesion molecules, and decreased angiogenic growth factors. However, the effect of diabetes on Ca2+ regulatory mechanisms in cardiac endothelial cells (CECs) remains unknown. The objective of this study was to determine the effect of diabetes on [Ca2+]i homeostasis in CECs in the rat model (streptozotocin-induced) of DCM. DCM-associated cardiac fibrosis was confirmed using picrosirius red staining of the myocardium. CECs isolated from the myocardium of diabetic and wild-type rats were loaded with Fura-2, and UTP-evoked [Ca2+]i transients were compared under various combinations of SERCA, sarcoplasmic reticulum Ca2+ ATPase (PMCA) and NCX inhibitors. Diabetes resulted in significant alterations in SERCA and NCX activities in CECs during [Ca2+]i sequestration and efflux, respectively, while no difference in PMCA activity between diabetic and wild-type cells was observed. These results improve our understanding of how diabetes affects calcium regulation in CECs, and may contribute to the development of new therapies for DCM treatment
May Measurement Month 2018: a pragmatic global screening campaign to raise awareness of blood pressure by the International Society of Hypertension
Aims
Raised blood pressure (BP) is the biggest contributor to mortality and disease burden worldwide and fewer than half of those with hypertension are aware of it. May Measurement Month (MMM) is a global campaign set up in 2017, to raise awareness of high BP and as a pragmatic solution to a lack of formal screening worldwide. The 2018 campaign was expanded, aiming to include more participants and countries.
Methods and results
Eighty-nine countries participated in MMM 2018. Volunteers (≥18 years) were recruited through opportunistic sampling at a variety of screening sites. Each participant had three BP measurements and completed a questionnaire on demographic, lifestyle, and environmental factors. Hypertension was defined as a systolic BP ≥140 mmHg or diastolic BP ≥90 mmHg, or taking antihypertensive medication. In total, 74.9% of screenees provided three BP readings. Multiple imputation using chained equations was used to impute missing readings. 1 504 963 individuals (mean age 45.3 years; 52.4% female) were screened. After multiple imputation, 502 079 (33.4%) individuals had hypertension, of whom 59.5% were aware of their diagnosis and 55.3% were taking antihypertensive medication. Of those on medication, 60.0% were controlled and of all hypertensives, 33.2% were controlled. We detected 224 285 individuals with untreated hypertension and 111 214 individuals with inadequately treated (systolic BP ≥ 140 mmHg or diastolic BP ≥ 90 mmHg) hypertension.
Conclusion
May Measurement Month expanded significantly compared with 2017, including more participants in more countries. The campaign identified over 335 000 adults with untreated or inadequately treated hypertension. In the absence of systematic screening programmes, MMM was effective at raising awareness at least among these individuals at risk
Pengaruh Konsentrasi Air Perasan Bawang Merah dan Bawang Putih Serta Waktu Perendaman terhadap Perkecambahan Benih Sambiloto (Andrographis Paniculata (Burm.f.) Nees)
Sambiloto (Andrographis paniculata (Burm.f.) Nees.) merupakan salah satu tanaman obat yang dapat diperbanyak secara generatif menggunakan benih. Benih sambiloto termasuk golongan benih ortodoks yang mengalami masa dormansi. Dalam proses perkecambahan benih diperlukan hormon pertumbuhan atau sering juga disebut sebagai Zat Pengatur Tumbuh. Bawang merah dan bawang putih merupakan salah satu sumber ZPT alami yang dapat digunakan dalam proses perkecambahan. Tujuan penelitian ini yaitu mengetahui pengaruh perendaman air perasan bawang merah dan bawang putih terhadap perkecambahan benih sambiloto serta mengetahui dosis dan waktu perendaman yang paling efektif meningkatkan perkecambahan benih sambiloto. Pada penelitian ini digunakan benih sambiloto yang telah mengalami masa penyimpanan selama 6 bulan. Konsentrasi yang digunakan pada penelitian ini yaitu 10%, 20% dan 40% dengan waktu perendaman 1 jam, 2 jam dan 4 jam. Hasil penelitian menunjukkan bahwa perlakuan jenis bawang mempunyai pengaruh yang signifikan terhadap jumlah benih berkecambah di petridish, jumlah daun, lebar daun dan tinggi kecambah. Sedangkan perlakuan konsentrasi dan lama waktu perendaman memberikan pengaruh yang tidak signifikan terhadap jumlah kecambah, jumlah daun, panjang daun dan tinggi kecambah. Kombinasi antar perlakuan tidak menunjukkan hasil yang signifikan sehingga dapat diartikan bahwa seluruh kombinasi perlakuan memberikan pengaruh yang hampir sama terhadap parameter pengamatan
