Studi Analisis Pengaruh Set-Back Pada Bangunan Bertingkat Akibat Gempa

Besarnya pengaruh set-back yang diakibatkan gaya gempa bergantung pada bermacam hal, salah satunya ialah loncatan bidang pada bangunan itu sendiri. Tujuan penelitian ini yaitu untuk mengetahui seberapa besar pengaruh set-back terhadap struktur pada bangunan bertingkat dan untuk mengevaluasi kinerja struktur bangunan dengan set-back jika ditinjau berdasarkan displacement dan drift ratio. Pada penelitian ini, bangunan dimodelkan setinggi 7 lantai dengan elevasi ketinggian 28 m menggunakan program SAP 2000 yang juga digunakan untuk menganalisis gaya gempa dengan metode spektrum respon ragam. Pemodelan yang diteliti sebanyak 3 pemodelan yaitu bangunan tanpa set-back, bangunan set-back dengan loncatan bidang kedalam, dan bangunan set-back dengan loncatan bidang keluar. Berdasarkan hasil penelitian yang telah dilakukan, pengaruh bangunan bertingkat akibat set-back baik loncatan bidang kedalam maupun keluar memiliki drift ratio yang besar bila dibandingkan dengan model struktur gedung tanpa set-back. Untuk model struktur gedung tanpa set-back dan model set-back dengan loncatan bidang kedalam struktur gedungnya aman, sedangkan untuk model set-back dengan loncatan bidang keluar struktur gedungnya tidak aman karena melebihi nilai batas ijin displacement dan drift ratio.                                                      

Adaptive mechanisms of plants against salt stress and salt shock

Salinization process occurs when soil is contaminated with salt, which consequently influences plant growth and development leading to reduction in yield of many food crops. Responding to a higher salt concentration than the normal range can result in plant developing complex physiological traits and activation of stress-related genes and metabolic pathways. Many studies have been carried out by different research groups to understand adaptive mechanism in many plant species towards salinity stress. However, different methods of sodium chloride (NaCl) applications definitely give different responses and adaptive mechanisms towards the increase in salinity. Gradual increase in NaCl application causes the plant to have salt stress or osmotic stress, while single step and high concentration of NaCl may result in salt shock or osmotic shock. Osmotic shock can cause cell plasmolysis and leakage of osmolytes in plant. Also, the gene expression pattern is influenced by the type of methods used in increasing the salinity. Therefore, this chapter discusses the adaptive mechanism in plant responding to both types of salinity increment, which include the morphological changes of plant roots and aerial parts, involvement of signalling molecules in stress perception and regulatory networks and production of osmolyte and osmoprotective proteins

Measuring State-Level Asian American and Pacific Islander Health Disparities: The Case of Illinois

Illinois is home to the sixth largest Asian American and Pacific Islander (AAPI) population nationwide. AAPIs suffer higher incidence, morbidity, and mortality rates from certain cancers, infectious, and chronic diseases. Despite the exponential growth of the AAPI population, few state-level data sources exist that provide detailed and accurate information regarding AAPI health disparities and needs. Efforts to improve health care for this population will require improved data collection and funding for research on AAPI ethnic groups

INFLUENCE OF MICRONUTRIENTS FORTIFIED MULBERRY LEAVES ON LARVAL GROWTH AND COCOON PARAMETERS OF MULBERRY SILKWORM, Bombyx mori L

The present study was conducted to know the effect of micronutrients on the growth and cocoon characters of silkworm, Bombyx mori L. The mulberry leaves (Morus alba) were fortified with minerals such as, zinc sulphate, copper sulphate and ferrous sulphate at different concentrations (5,10,15,20 and 25 ppm) and fed to the silkworm. Among these five concentrations tested , it was observed that the zinc sulphate at 15 ppm, copper sulphate at 10 ppm and ferrous sulphate at 20 ppm registered higher mature larval weight, effective rate of rearing, cocoon weight, shell weight, shell ratio and filament length than the control and other treatments

Growth, crystal structure and thermal properties of calcium bis(malate) dihydrate

A new coordination compound crystal of calcium with malic acid is prepared by gel aided solution growth. Single crystal X-ray diffraction studies revealed that the structural formula of the compound is Ca(C4H4O5)2·2H2O. It crystallizes in the monoclinic system with space group C2/c, Z=4, with unit cell parameters a=15.916(9)Å, b=5.886(3)Å, c=13.046(6)Å and β=90.678(4)°. Data were collected by oscillation method and full-matrix least squares refinement was applied to the model converging to final R indices R1=0.0416 and ωR2=0.1255. Compound forms a layer-type polymeric structure, stabilized by intermolecular hydrogen bonding. Ca2+ is eight-fold coordinated. Malate is coordinated to Ca2+ tridendate–bidendate through two carboxylates and monodendate through oxygen atom of the hydroxyl group. Thermal behavior investigated using TG and DTA studies is in conformity with the proposed structure
