Analisa Sistem Distribusi Air Pdam Di Desa Pemongkong Kec. Jerowaru Kab. Lombok Timur

In the process of the distribution of clean water to a village Pemongkong, debit frequent shortages in some villages, so this study will look at what factors cause the flow rate is very low in some villages.Generally, public needs can still be met. It can be seen from the average requirement (debit demand) daily by SKAB DPU of 9.96 L/s, while the available flow at the source from January-August 2012 more than 9.96 L/s. Then a decline debit from September-December 2012, so that people\u27s needs can not be met. Nevertheless, at the peak hours several sub-village get very low flow rates. This is because the discharge limitations provided by the source, where the maximum discharge generated by the source of 12.4 L/s, while the demand at the peak hours is 22.09 L/s.Further analyzes about head loss and preesure residu, at peak hours for maximum USAge (February 2012) there are two sub-villages that experienced head press remaining fairly low compared to other sub-villages. These sub-villages are Ujung of 20,15 m and Permas of -2,81 m. This leads to a potential barrier to the flow of these sub-villages is quite high, and water will tend to flow towards the place where the head pressure residual higher. This problem can be overcome by increasing the transmission diameter pipe from 2 ince to 3 ince. This problem can be overcome by increasing the diameter of the transmission pipeline to both the village of 2 to 3-in ince. Head hit the rest is generated after using the 3-in-diameter pipe is in the end based on manual calculations hamlet of 111.31 m, and based on simulations Epanet 2.0 at 112.45 m, while in the hamlet Permas based on manual calculations of 102.72 m and based on simulation Epanet 2.0 at 103.01 m. &nbsp

Stress Echo 2030 Study: A Flagship Project of the Italian Society of Echocardiography and Cardiovascular Imaging

Over the past decade, stress echocardiography has evolved from a test for assessing epicardial artery stenosis to a comprehensive functional test, targeting multiple cardiovascular parameters. The new approach includes several structured steps: (a) evaluating regional wall motion abnormalities to detect epicardial artery stenosis or vasospasm; (b) assessing pulmonary congestion and diastolic function via B‐lines with lung ultrasound; (c) gauging preload and contractile reserve with volumetric echocardiography; (d) measuring coronary microvascular reserve using Doppler‐based coronary flow velocity in the middistal left anterior descending artery; and (e) determining cardiac sympathetic reserve by tracking heart rate reserve on an ECG. This evolution was supported extensively by the Italian Society of Echocardiography and Cardiovascular Imaging (SIECVI), whic

Normal and abnormal development of the aortic wall and valve: correlation with clinical entities

Dilation of the wall of the thoracic aorta can be found in patients with a tricuspid (TAV) as well as a bicuspid aortic valve (BAV) with and without a syndromic component. BAV is the most common congenital cardiovascular malformation, with a population prevalence of 0.5–2 %. The clinical course is often characterised by aneurysm formation and in some cases dissection. The non-dilated aortic wall is less well differentiated in all BAV as compared with TAV, thereby conferring inherent developmental susceptibility. Furthermore, a turbulent flow, caused by the inappropriate opening of the bicuspid valve, could accelerate the degenerative process in the aortic wall. However, not all patients with bicuspidy develop clinical complications during their life. We postulate that the increased vulnerability for aortic complications in a subset of patients with BAV is caused by a defect in the early development of the aorta and aortic valve. This review discusses histological and molecular genetic aspects of the normal and abnormal development of the aortic wall and semilunar valves. Aortopathy associated with BAV could be the result of a shared developmental defect during embryogenesis

Communicating Information on Eruptions and Their Impacts from the Earliest Times Until the Late Twentieth Century

Volcanoes hold a fascination for human beings and, before they were recorded by literate observers, eruptions were portrayed in art, were recalled in legends and became incorporated into religious practices: being viewed as agents of punishment, bounty or intimidation depending upon their state of activity and the culture involved. In the Middle East the earliest depiction of an eruption is a wall painting dating from the Neolithic at Çatal Hüyük and the earliest record dates from the third millennium BCE. Knowledge of volcanoes increased over time. In some parts of the world knowledge of eruptions was passed down by oral transmission, but as far as written records were concerned, in the first century CE only 9 volcanoes in the Mediterranean region were recognised, together with Mount Cameroon in West Africa. In the next 1000 years the list grew by 17, some 14 of these volcanoes being in Japan. The first recorded eruptions in Indonesia occurred in 1000 and 1006, and volcanoes in newly settled Iceland increased the number to just 48 in 1380 CE. After this the list continued to increase, with important regions such as New Zealand and Hawaii only being added in the past 200 years. Only from 1900 did the rate of growth decline significantly (Simkin et al. 1981: 23; Simkin, 1993 Siebert et al. 2011; Simkin, 1993), but it is sobering to recall that in the twentieth century major eruptions have occurred from volcanoes that were considered inactive or extinct examples including: Mount Lamington - Papua New Guinea, 1951; Mount Arenal - Costa Rica, 1968 and Nyos - Cameroon, 1986. Although there are instances where the human impact of historical eruptions have been compiled - with examples including the 1883 eruption of Krakatau (Simkin and Fiske (1983) and 1943 -1952 eruption of Parícutin (Luhr and Simkin, 1993) - these are exceptions and there remains a significant gap in knowledge about both the short and long-term effects on societies of major eruptions which occurred before the 1980s. Following a broad review the chapter provides a discussion of the ways in which information has been collected, compiled and disseminated from the earliest times until the 1980s in two case study areas: the Azores Islands (Portugal) and southern Italy. In Italy information on eruptions stretches back to prehistoric times and has become progressively better known over more than 2,000 years of written history, yet even here there remain significant gaps in the record even for events that took place between 1900 and 1990. In contrast, located in the middle of the Atlantic, the Azores have been isolated for much of their history and illustrate the difficulties involved in using indigenous sources to compile, not only assessments of impact, but also at a more basic level a complete list of historical events with accurate dates

Pengaruh Pengetahuan, Kemampuan dan Pengalaman Kerja terhadap Kinerja Karyawan pada PT. Hilon Sumatera

The purpose of this study is to determine the effect of knowledge, abilities, and work experience towards employee performance at PT. Hilon Sumatera. The analytical method used is multiple linear regression analysis. The amount of population in this study is 53 people. The sampling method used is by doing census so that the amount of samples is also 53 people. The data was collected by using questionnaire, interview, and documentation study. From the result of the research, it is discovered that the coefficient of determination (R Square) is 0,593 or 59,3%. This means that the variations in employee working performance can be determined by variations in organizational commitment and working discipline by 59,3%, while the rest 40,7% is determined by other variables not included in this research, such as motivation, working discipline, morale, supervision, and leadership method. The multiple linear regression equation obtained from the data processing result is Y=6,161+0,346X1+0,286X2+0,186X3+ ei, which means that knowledge, abilities, and working experience are positively affecting the employee performance at PT. Hilon Sumatera. Hypothesis testing simultaneously shows that knowledge, abilities, and working experience are having a significant effect towards employee performance at PT. Hilon Sumatera. Partial Hypothesis Test (T Test) shows that knowledge has a positive and significant effect on employee performance, with a significance level of 0,000 α (0,05), and working experience with a significance level of 0,013< α (0,05). Refering to the results of this study, it is reccomended that PT. Hilon Sumatera should develop and maintain the indicators that are available on knowledge, abilites, and working experience
