Abstract The potential for fish production is very important as a necessary material for WPP PD in making policies. Estimation of fishery production potential is adjusted to aquatic ecosystem. The method used differs between running and stagnant water based on the shape of the water. Fishery resources in Indonesia, especially inland fisheries, still cannot be managed and utilized optimally and sustainably. The method used in estimating fishery stocks in the watershed is the Leger-Huet method. Research to estimate fish production potential using the benthic biomass approach using the Leger-Huet method was carried out in February, June, and October 2019 in the Sumani River and Ombilin River, Singkarak Lake. The research objective was to determine the estimated value of fish production potential through the benthic biomass approach in the Sumani River (Inlet) and Ombilin River (Outlet), Singkarak Lake. The calculation of benthic biomass and fish production potential was carried out at the Testing Laboratory of the Research Institute for Inland Fisheries and Extension in Palembang. This system is expected to be able to provide alternative solutions for decision-making and agencies to determine the potential for fish production in an area. The determination of the potential for fish production using the benthic biomass approach is highly dependent on the width of the river. The results showed that the types of benthos in the Sumani and Ombilin rivers were 5 classes and 17 families. The benthos found by the Ombilin River are more varied than those in the Sumani River, and the estimated fish production potential of the Ombilin River is greater than that of the Sumani River. The highest yield of benthic biomass was found in the Ombilin River (159.06 gr/m2) compared to the Sumani River (76.06 gr/m2). Meanwhile, the average potential fish production in the Batang Sumani River (573.8 (kg/ha) is higher than in the Ombilin River (244.74 kg/ha).

With over 50 million students, Indonesia has the fourth largest education system in the world. The first twelve years of education are compulsory for all citizens. The students, together with over 3 million teachers spend six (or five in some cases) days a week at over 300,000 schools, typically from 6:30 AM to 2 (or 3) PM. Geographically, Indonesia is traversed by the infamous “ring of fire” and prone to natural events resulting from the tectonic plate movements of the Australian Plate from the South, the Eurasian and Sunda Plates from the North and the Philippine Plate from the East. Left unmitigated, these natural events would lead to natural disasters emanating from resulting earthquakes and leading to tsunamis, landslides, the collapse of building structures and failure of lifelines (roads, pipelines, electrical grid, etc.). In an effort to provide disaster-safe schools, the National Agency for Disaster Management has required that school facilities be a community center in case of disasters and serve as emergency shelters. Retrofit of existing buildings will be needed to comply with government guidelines. This paper presents a case study of the determination of structural deficiencies of an existing school building in SDN 42 Korong Gadang, Padang, West Sumatra and implementation of a seismic retrofit (design and construction) at the same building to mitigate potential earthquake disaster.

Lolitrem B

Perennial ryegrass (Lolium perenne) straw is used as a feed for livestock and horses. Some straw is infected with the endophyte, Neotyphodium lolii, which produces lolitrem tremorgens. Ingesting of the toxin produces clinical "ryegrass staggers." A 28 day feeding trail was conducted using 61 Black Angus, pure and crossbred cattle. The cattle were fed one of three levels of lolitrem B in chopped perennial ryegrass straw ranging from 0 ppb up to 3058 ppb. Four Japanese Wagyu crossbred cattle were fed chopped ryegrass straw containing 1400 ppb lolitrem B. The cattle were evaluated and scored twice a day for clinical signs of gait difficulties. Cattle consuming 1400 ppb lolitrem B did not show any overt clinical signs. After 14 days, 7 out of 15 cattle in the 1954 ppb lolitrem B group showed clinical signs of ataxia, stiffness, and tremors as seen in ryegrass staggers. All of the cattle in the positive control group of up to 3058 ppb lolitrem B with a 4 week mean of 2574 ppb developed clinical signs of staggers. None of the Wagyu cattle at 1400 ppb lolitrem B developed clinical signs. A dose response curve was developed based on the results of this study coupled with a prior study for use in the testing laboratory.

Specific Definition

AbstractThe karst environment presents a special challenge when it comes to identifying groundwater/surface-water interactions. Existing definitions of areas of regular flooding in karst regions are too general and lack a measurable approach for the determination of flood-liable land. This paper proposes a means of specific definition and quantitative determination of intermittently flooded karst areas, which takes into account the extent, duration and frequency of flooding, and includes the identification of data sources and processing methods. The procedure, involving spatial layers, was developed using a pilot area and tested in three additional areas in Slovenia. The derived definition determines that flood-liable land within karst poljes and intermittent lakes comprise areas where stagnant water or stream overflow is present for at least 10 days/year over a period of 30 years, and these waters have direct contact with groundwater. The results show that the proposed procedure is applicable to areas with different geomorphological settings and to areas where the quantity and quality of available data vary. The study is an example of the practical application of knowledge on karst, as the findings can be used for short-term purposes (mapping flood areas, determination of habitats) and long-term purposes (study of impacts of environmental changes). Attention should be drawn to the lack of available data and the fact that the national networks of hydrological observatories are often too sparse for this purpose. This study raises awareness of these shortcomings and improves the planning or expansion of such a network in collaboration with experts.

The paper presents the results of an experimental investigation conducted on bricks. Prism-shaped specimens were produced. Laboratory tests were carried out at the Non-Destructive Testing Laboratory of the Politecnico di Torino. They were subjected to static compressive tests for the determination of their mechanical properties and cyclic compressive tests for the analysis of their fatigue behaviour. The aim of this work is to apply a failure criterion based on the observation of the static and cyclic curves to estimate the fatigue life and the long-term behaviour of the brick. Subsequently, it will be possible to give a relation between the static-displacement and cyclic-displacement of the material tested.

The economic effect of buildings’ renovation largely depends on implementation of energy saving methods and devices. A very high economic effect is achieved by wall insulation. In this respect, it is even higher than the replacement of windows. The alternative solutions of wall insulation of buildings differ in the materials used, labour expenditure and other aspects. The cost of renovation depends on the solutions made. The criteria describing the available wall insulation alternatives may have different values. Moreover, they may change in different directions, i.e. a higher value of some criteria denotes a better state, while for others they mean a worse situation. In this environment, a compromise variant is required, which can be found by multicriteria evaluation methods. To reduce the effect of various methods on calculation results, it can be recommended to assess the object (or phenomenon) considered by several different methods, with a subsequent determination of the average estimate value. In this way, the disadvantages of some particular multicriteria evaluation methods could be compensated by the advantages of others. The integration of methods will be correct if there is a correlation between the values obtained by different methods. Santrauka Ekonominis pastatų renovacijos efektyvumas priklauso nuo energiją taupančių priemonių įgyvendinimo. Pastatų sienų šiltinimas yra viena iš geriausių priemonių ir net efektyvesnis energijos taupymo požiūriu negu langų keitimas. Pastatų sienų šiltinimo variantai skiriasi vienas nuo kito pagal medžiagas, darbo sąnaudas ir pan. Nuo to priklauso renovacijos kaina. Kriterijai, atspindintys skirtingus sienų šiltinimo variantus, gali turėti įvairių reikšmių. Gali skirtis jų kitimo kryptys, t. y. vienų kriterijų reikšmių didėjimas padėtį gerina, kitų – blogina. Kompromisiniam variantui pasirinkti padeda daugiakriterio vertinimo metodai (MCDA). Norint mažinti metodų specifikos įtaką skaičiavimų rezultatams, tą patį nagrinėjamą reiškinį tikslinga vertinti keliais būdais, paskui nustatyti šio vertinimo vidurkį. Tokiu atveju vienų daugiakriterio vertinimo būdų trūkumus kompensuoja kitų būdų privalumai. Metodų susiejimas bus korektiškas, jeigu reikšmės, gautos naudojant įvairius būdus, tarpusavyje koreliuoja.

<p>Medication errors, ranging from prescription to administration errors, are still problems of patient safety with an average error rate of 8% - 10% and can cause severe morbidity, prolonged length of stay (LOS) in a hospital, unnecessary diagnostic tests and care, and mortality. The objective of this study is to describe the number of medication errors and their potential causes according to the perceptions of health personnel. The study was carried out by questionnaires, interviews, and data exploration on prescriptions made before the observation period and new prescriptions made during the observation period. The priority determination of the solutions was carried out using Capability, Assessibility, Readiness, and Leverage method (CARL) and discussions with related units. The priority root factors that caused medication errors in the inpatient pharmacy at RSI Malang were high workloads and high turnover of inpatient pharmacist, incomplete prescription identity, illegible doctor's writing, and lack of training for the pharmacist. The priority outcome of the alternative solutions to overcome the medication errors in inpatient pharmacist is to regularly conduct training or knowledge refreshing for the inpatient pharmacist at RSI Malang and the implementation of e-prescription.</p>
