No full textTechnology Transfer to Small Scale Industries
No full textThe paper discusses the role of small scale industries (SSI)in the growth of national economy. The small scale industries contributes substantially in the employment generation industrial production and experts. The difficulty faced in adopting new technologies by SSI
entrepreneur has been explained. The author points out that in many cases the know how developed in the laboratories do not have cost analysis, details of equipment required for setting up the plant based
on the basis of know how. The author suggests that the small scale industries can support R&D only when the technology is fully established before that the expenses incurred in the development of technology for SSI should be reimbursed by the ministry of small scale industries. However, the facilities for trials be extended by small scale industries. The collaboration between SSI and R&D institutes will go in long way in improving the economy of state/centers
Dr. B.R. Ambedkar\u27s Vision of Indian Polity: Equality, Justice, and Social Transformation
No full textDr. B. R. Ambedkar, a well-known social activist as well as distinguished philosopher, was genuinely worried regarding the situation of the marginalised at the start of his distinguished career. He spent his whole life working to improve social and economic circumstances. Ambedkar\u27s transformative vision directs individual\u27s efforts as assists with renegotiating issues, particularly the collapse of modern political thought. Ambedkar became well-known as a key strategic philosopher throughout today\u27s society following the rise of the dalit struggle. He rose to prominence in India\u27s sociopolitical environment during the 1920s. With terms of political, economic, social or religious views, he was crucial to the improvement of the least rung of so-called indestructible Indian community. Furthermore, he was a brilliant sociologist, economist, judicial analyst, educationist, author, legislator, advocate, or rights-based activist. He was an iconoclast as well as researcher who successfullly organised, emancipated, or united the uneducated Indians opposing all forms of societal and political tyranny. This investigation captures Ambedkar\u27s views on politics
An Inventory and Assessment of Sample Sources for Survey Research with Agricultural Producers in the U.S.
No full textResearchers need probability samples to collect representative survey data about the behaviors and attitudes of agricultural producers they study in relation to the natural resources that they manage, yet obtaining accurate and complete sampling frames is challenging. We extract data from a publication database to identify the most commonly used sampling frame sources in survey research of agricultural producers in the U.S., finding that government program participant lists are used most often, while private vendor samples are increasingly being purchased. Based on our research experience, we find that for many projects, private vendors can provide the most rigorous samples. Given that survey methods remain a useful and popular method for studying the behaviors and attitudes of producers on a variety of topics, such an assessment and guide is needed for researchers and practitioners.This article is published as Ulrich-Schad, Jessica D., Shuang Li, J.

Magneto-optical properties of CoFeB ultrathin films: Effect of Ta buffer and capping layer
No full textMechanism of action of ID4 as a tumor suppressor, 2016
No full textInitial studies demonstrated that Inhibitor of DNA binding/differentiation protein 4 (Id4) acts as a tumor suppressor in prostate cancer (PCa). To further confirm and investigate the mechanism by which ID4 acts as a tumor suppressor, herein we concentrated on two different approaches. In the first approach we investigated ID4 role as a tumor suppressor by regulating AKT/PI3K pathway. In the second approach, we examined the role ofld4 in blocking the tumorogenic properties of metastatic PC3 cells. Phosphoinositide 3-kinase/Protein kinase B (PB/AKT) pathway regulates multiple biological processes leading to cell survival, proliferation and growth in cancerous cells. We performed immunohistochemistry (IHC) to determine AKT, pAKT and PTEN protein expression in Id4 knockout mouse prostates and PCa cell lines. IHC on Id4 knockout mouse prostates demonstrated a significant decrease in PTEN expression as compared to normal mouse prostates. Consistent with decrease PTEN, the expression of pAKT expression increased. Similar pattern was observed in PCa cell lines: DU145 cells lacking Id4 had low PTEN as compared to ld4 over-expressing DU 145 cells. In addition, Chromatin immunoprecipitation (Ch!P) analysis also demonstrated an increase in the binding of acetylated p53 on PTEN promoter in the presence of Id4. The second approach demonstrated the tumor suppressor function of Id4 in highly tumorogenic and metastatic PC3 cell line. Interestingly, this study demonstrated that overexpression of Id4 in PC3 cells results in decreased tumorogenecity in part through increased expression of Androgen receptor (AR) and its target genes Cyclin dependent inhibitor I (p21) and FK506-binding protein 51 (FKBPS l ). Apoptosis, migration and cell proliferation decreased in the Id4 overexpressed PC3 cells. Mice injected with PC3 + Id4 cells showed decreased tumor size and volume. IHC studies on tumor xenografts demonstrated increased levels of AR, Ki67, and p21 in Id4 overexpressed xenograft. Collectively, our data indicate that 1D4 acts as tumor suppressor by regulating the levels of PTEN by prompting the binding ofacetylated p53 onto PTEN promoter which eventually results in inhibiting P13K/AKT pathway. Furthermore, Id4 not only increases the expression of AR in PC3 cells but also regulates the factors responsible for AR tumor suppressor activity
Growth and dynamic magnetization study of Co2MnAl full Heusler alloy thin films
No full textStructural and dynamic magnetization properties of Co2MnAl (CMA) full Heusler alloy thin films grown on Si (100) substrates at different substrate temperatures (T-s) room temperature (RT), 200 degrees C, 300 degrees C, 400 degrees C and 500 degrees C are investigated. X-ray diffraction patterns revealed the formation of B2 ordered phase. Ferromagnetic Resonance (FMR) technique have been used to investigate the dynamic magnetization response. From the observed frequency dependence of the resonance field (H-r) and line width (Delta H), the effective saturation magnetization (4 pi M-eff) and damping constant () have been evaluated. The lowest damping constant was found to be 0.007 +/- 0.002 for the film grown at T-s=200 degrees C which is comparable to the reported value.</p
Effect of post-annealing on the magnetic properties of sputtered Mn56Al44 thin films
No full textMa(56)Al(44) (MnAl) thin films of constant thickness (similar to 30nm) were grown on naturally oxidized Si substrates using DC-magnetron sputtering. Effect of deposition parameters such as sputtering power, substrate temperature (T-s), and post-annealing temperature have been systematically invstigated. X-ray diffraction patterns revealed the presence of mixed phases, namely the tau- and beta-MnAl. The highest saturation magnetization (M.$) was found to be 65emu/cc using PPMSVSM in film grown at T-s =500 degrees C. The magnetic ordering was found to get significantly improved by performing post annealing of these as-grwon at 400 degrees C for 1 hr in the presence of out-of-plane magnetic field of similar to 15000e in vacuum. In particular, at room temperature (RT), the Ms got enhanced after magnetic annealing from 65mm/cc to 500 emu/cc in MnAl films grown at T-s=500 degrees C. This sample exhibited a magneto-resistance of similar to 1.5% at RT. The tuning of the structural and magnetic properties of MnAl binary alloy thin films as established here by varying the growth parameters is critical with regards to the prospective applications of MnAI, a metastable ferromagnetic system which possesses the highest perpendicular magnetic anisotropy at RT till date.</p
