Design of reinforced concrete beams with web openings

The provision of transverse openings in floor beams to facilitate the passage of utility pipes and service ducts results not only in a more systematic layout of pipes and ducts, it also translates into substantial economic savings in the construction of a multi-storey building. To investigate the problem of openings in beams, the author initiated a research program in the early 1980s. Since then extensive research has been carried out giving a comprehensive coverage on both circular and large rectangular openings under various combinations of bending, shear and torsion. In this paper, major findings relevant to the analysis and design of such beams under the most commonly encountered loading case of bending and shear are extracted and summarized. An attempt has been made to answer the frequently asked questions related to creating an opening in an already constructed beam and how to deal with multiple openings. It has been shown that the design method for beams with large openings can be further simplified without sacrificing rationality and having unreasonable additional cost

An Investigation of the Ability to Recover from Transients Following Failures for Single-Pilot Rotorcraft

A moving-base simulation was conducted to investigate a pilot's ability to recover from transients following single-axis hard-over failures of the flight-control system. The investigation was performed in conjunction with a host simulation that examined the influence of control modes on a single pilot's ability to perform various mission elements under high-workload conditions. The NASA Ames large-amplitude-motion Vertical Motion Simulator (VMS) was utilized, and the experimental variables were the failure axis, the severity of the failure, and the airspeed at which the failure occurred. Other factors, such as pilot workload and terrain and obstacle proximity at the time of failure, were kept as constant as possible within the framework of the host simulation task scenarios. No explicit failure warnings were presented to the pilot. Data from the experiment are shown, and pilot ratings are compared with the proposed handling-qualities requirements for military rotorcraft. Results indicate that the current proposed failure transient requirements may need revision

Lifestyle measures for primary prevention of T2 Diabetes Mellitus (T2DM)

Worldwide, the number of adults with diabetes was 285 million in 2010 and it will be 439 million in the year 2030. Although the genes we inherit may influence the development of type 2 diabetes, they take a back seat to behavioral and lifestyle factors. Data from the Nurses’ Health Study suggest that 90 percent of type 2 diabetes in women can be attributed to five such factors: excess weight, lack of exercise, a less-than-healthy diet, smoking, and abstaining from alcohol. From this data it can be said that up to 90 percent of diabetes prevention is possible with behavioral and lifestyle factors intervention. This intervention should be given to the people through primary prevention. The purpose of primary prevention is to limit the number of people who develop a disease by controlling causes and risk factors for the disease

One-Pot Aqueous Synthesis of Fluorescent Ag-In-Zn-S Quantum Dot/Polymer Bioconjugates for Multiplex Optical Bioimaging of Glioblastoma Cells

Cancer research has experienced astonishing advances recently, but cancer remains a major threat because it is one of the leading causes of death worldwide. Glioblastoma (GBM) is the most malignant brain tumor, where the early diagnosis is vital for longer survival. Thus, this study reports the synthesis of novel water-dispersible ternary AgInS2 (AIS) and quaternary AgInS2-ZnS (ZAIS) fluorescent quantum dots using carboxymethylcellulose (CMC) as ligand for multiplexed bioimaging of malignant glioma cells (U-87 MG). Firstly, AgInS2 core was prepared using a one-pot aqueous synthesis stabilized by CMC at room temperature and physiological pH. Then, an outer layer of ZnS was grown and thermally annealed to improve their optical properties and split the emission range, leading to core-shell alloyed nanostructures. Their physicochemical and optical properties were characterized, demonstrating that luminescent monodispersed AIS and ZAIS QDs were produced with average sizes of 2.2 nm and 4.3 nm, respectively. Moreover, the results evidenced that they were cytocompatible using in vitro cell viability assays towards human embryonic kidney cell line (HEK 293T) and U-87 MG cells. These AIS and ZAIS successfully behaved as fluorescent nanoprobes (red and green, resp.) allowing multiplexed bioimaging and biolabeling of costained glioma cells using confocal microscopy

Rasionalitas Orientasi Politik Masyarakat Nelayan Pada Pemilihan Umum Di Kabupaten Majene

This study aims to determine and analyze the political orientation of the fishing communities in Majene Regency which is also associated with their rationality in voting in elections. This research was conducted in Majene Regency, West Sulawesi Province, using qualitative research type with descriptive type of analysis. Determination of informants was conducted purposively. Data was obtained through in-depth interviews and literature review. Data was analyzed using political orientation theory, rational choice theory, Coleman and other rationality concepts. The results showed that cognitive orientation, fishermen's knowledge of the general election was still very low. In making political decisions, they do not consider the program and vision and mission of the political parties but only consider the figures they know and like. In the affective orientation aspect, fishermen do not feel that the results of the previous elections can benefit their lives so that they will not consider the results of the party's performance. last election. This is due to the emergence of disappointment at the performance of political parties in the previous election. aspects of evaluative orientation, fishermen will still distribute their political rights in elections but their decisions are based on decisions for their comfort and security to live in rented land or loans from landlords who also direct fishermen to choose the candidate that the landlord wants. The decision to vote was also based on the rise of money politics by the candidates.Penelitian ini bertujuan untuk mengetahui dan menganalisis orientasi politik masyarakat nelayan yang ada di Kabupaten Majene yang dikaitkan pula dengan rasionalitas mereka dalam memilih pada pemilihan umum. Penelitian ini dilaksanakan di Kabupaten Majene Provinsi Sulawesi Barat, menggunakan jenis penelitian kualitatif dengan tipe deskriptif analisis. Penentuan informan dilakukan secara purposive. Data diperoleh melalui wawancara mendalam dan kajian pustaka. Data dianalisis menggunakan teori orientasi politik, teori pilihan rasional Coleman dan konsep rasionalitas lainnya. Hasil penelitian menunjukan bahwa secara orientasi kognitif, pengetahuan nelayan tentang pemilihan umum masih sangatlah rendah. Mereka dalam mengambil keputusan politik tidaklah mempertimbangkan program dan visi misi partai politik melainkan hanya pertimbangan sosok figure saja yang mereka kenal dan sukai. Aspek orientasi afektif, nelayan tidak merasakan hasil pemilu yang terdahulu dapat bermanfaat bagi kehidupannya sehingga mereka dalam memilih tidak akan mempertimbangkan kinerja partai hasil pemilu yang lalu. Hal ini dikarenakan munculnya rasa kekecewaan akan kinerja partai politik yang ada pada pemilu sebelumnya. aspek orientasi evaluatif, nelayan tetap akan menyalurkan hak politiknya di pemilihan umum tetapi keputusan mereka didasarkan oleh keputusan untuk kenyamanan dan keamanan mereka untuk tinggal di lahan sewaan atau pinjaman para tuan tanah yang juga mengarahkan nelayan untuk memilih kandidat yang tuan tanah inginkan. Keputusan memilih juga didasari oleh maraknya politik uang oleh para kandidat

Potensi dan Strategi Pengembangan Bank Syariah di Indonesia: Kajian Produk Syariah dari Segi Fiqih Muamalat

At the present, Indonesia operate dual banking system that are conventional banking system with its interest rate runs side by side and the Islamic banking with the profit-sharing/non-interest system of its own. Islamic banking using fiqih muamalat as the basic theory in the syariah product. In general, communitys respond toward Islamic bank is good relatively that shown by the trend of Third Parties Funding and Financing to Deposit Ratio with low level of Non Performing Loan. This paper assess the consumers preference toward both conventional and Islamic banking, in related with analysis of potency and development strategy of Islamic banking in Indonesia by using fiqih muamalat as the basic theory. The analysis of data by using qualitatively (descriptive) analysis, cross tabulation, and logistic regression model. Literature study used in this paper. In general, communitys attitude toward interest rate system still ambiguous, that are interest rate is contrary to syariah of Islam, meanwhile in banking transaction they still use conventional system. The reasons that motivate consumer to adopt Islamic banking related to professionalism of bank, security, and pleasure in doing transaction, strategic location, and the implementation of syariah system. However, community still has difficulties to comprehend the technical term of Islamic banking. Thus, socialization and education process about economic system of Islam (syariah economic) designate necessary requirement in encourage the development of Islamic banking in the future
