The Poverty that is revealed in the Short Stories of Pa. Jayaprakasam

Poverty is deadly. It can be said that poverty is coupled with Karisal's life. A man always has to fight with society for his economic upliftment. The Karisal region is sky-seeing earth known for its drought, heat, and mirage. Therefore, poverty and persecution are related phenomena that rob human life. Drought occurs due to poverty. As a result, agriculture does not take place. Poverty is caused by economic problems. Due to this, the local community is also seen as being full of problems. In this study, we will examine the sufferings of people due to the poverty that Pa. Jayaprakasam has created in his stories

Penerapan Model Kooperatif Tipe Tsts Terhadap Peningkatan Hasil Belajar IPA Siswa SD

This study aims to determine the increase in science learning outcomes through the TSTS type cooperative model for elementary students. Descriptive qualitative approach with type of classroom action research. Research focus of teacher, student and learning outcomes fator. The research subjects were 24 students of SDN No. 162 Poleonro 2016/2017 school year. Data collection techniques for observation, tests and documentation. Quantitative and qualitative analysis techniques with a success indicator of 70% of students scored above 78. The results showed the application of the TSTS type cooperative model in science learning in class V SD was carried out according to the plan in each cycle. Teachers and students are able to make improvements from the results of reflection on the actions of the first cycle of action in the next cycle. So that the application of the cooperative model Type TSTS can improve the learning outcomes of grade V elementary school students. Where in each cycle has increased learning outcomes, namely in the first cycle (first) students are still confused with their role in the group and in the second cycle (second) all students act according to their role in the group

WOS: A1992HQ04700016A transport method is described which reduces greatly the number of calibration standards needed for hydrogen analysis by neutron induced prompt gamma-rays. The counts in the photopeaks from neutron capture in hydrogen for various standard concentrations, the distribution of the source neutron rate entering the thermal group and the reaction rates in the samples are investigated theoretically using 100 energy group cross sections and experimental Cf-252 spectra for a test configuration. Comparison of theoretical results with those measured from the test configuration shows good agreement

Visible and infrared photocurrent enhancement in a graphene-silicon Schottky photodetector through surface-states and electric field engineering

The design of efficient graphene-silicon (GSi) Schottky junction photodetectors requires detailed understanding of the spatial origin of the photoresponse. Scanning-photocurrent-microscopy (SPM) studies have been carried out in the visible wavelengths regions only, in which the response due to silicon is dominant. Here we present comparative SPM studies in the visible ($\lambda$ = 633nm) and infrared ($\lambda$ = 1550nm) wavelength regions for a number of GSi Schottky junction photodetector architectures, revealing the photoresponse mechanisms for silicon and graphene dominated responses, respectively, and demonstrating the influence of electrostatics on the device performance. Local electric field enhancement at the graphene edges leads to a more than ten-fold increased photoresponse compared to the bulk of the graphene-silicon junction. Intentional design and patterning of such graphene edges is demonstrated as an efficient strategy to increase the overall photoresponse of the devices. Complementary simulations and modeling illuminate observed effects and highlight the importance of considering graphene's shape and pattern and device geometry in the device design

Radiosensitivity of Amla (Emblica officinalis Gaertn.) Varieties Treated with Gamma Rays

Investigations were carried out at the Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore, during 2003-2005 to work out radiosensitivity of five varieties of amla (Emblica officinalis Gaertn.) exposed to different doses of gamma rays. Scions of five amla varieties, viz., BSR-1, Kanchan, Krishna, NA-7 and Chakaiya, were irradiated with different doses (1.0 to 5.0 kR) and these were grafted on to rootstocks. Based on the sensitivity study, LD50 for 100% survival ranged from 1.0 to 2.0 kR for all the five varieties. All the amla varieties could survive upto 10-20% at lower doses (upto 2.5 kR)

Evaluation of F1 Hybrids of Pumpkin (Cucurbita moschata Duch. Ex Poir) for Yield and Quality

An investigation was carried out to study the performance of 36 hybrids of pumpkin (Cucurbita moschata Duch. ex Poir) through Line x Tester mating design. Observations were recorded on the traits, viz., vine length, days to first female flower appearance, node number for first female flower appearance, sex ratio, days to first harvest, fruit number per vine, fruit weight, flesh thickness and fruit yield per vine, besides quality traits such as total carbohydrate content, total carotenoid content and crude fibre content in the fruit. Among the 36 hybrids of pumpkin studied, the cross 'Kasi Harit x Avinashi Local' excelled in yield per vine, followed by the crosses 'Vadhalagundu Local x CO-2' and 'Narendra Uphar x CO-2', respectively. Thus, first generation hybrids can be well-utilized for exploiting hybrid vigour to achieve improved quality
