Environmental Qualification of Buffer Amplifier Unit Using CATH Test Facility for SARAS Aircraft Program

The Buffer Amplifier Unit (BAU) was subjected to Temperature variation and Altitude tests in a Combined Altitude, Temperature and Humidity chamber. This unit was design and developed by Aerospace Electronics Division (ALD), NAL for Saras Aircraft. These tests were done as per RTCA - DO160E, Cat.C, Sec.5.3.1 & Sec. 4.6.1. After conditioning, the functional test was carried out by the firm and the unit was handed over to the firm

Control and Indication Unit (CIU). The CATH test was done as per MIL-STD 810F, Method 520.2. After conditioning, the functional test was carried out by the firm and the unit was handed over to them

Multiple novel prostate cancer susceptibility signals identified by fine-mapping of known risk loci among Europeans

Genome-wide association studies (GWAS) have identified numerous common prostate cancer (PrCa) susceptibility loci. We have fine-mapped 64 GWAS regions known at the conclusion of the iCOGS study using large-scale genotyping and imputation in 25 723 PrCa cases and 26 274 controls of European ancestry. We detected evidence for multiple independent signals at 16 regions, 12 of which contained additional newly identified significant associations. A single signal comprising a spectrum of correlated variation was observed at 39 regions; 35 of which are now described by a novel more significantly associated lead SNP, while the originally reported variant remained as the lead SNP only in 4 regions. We also confirmed two association signals in Europeans that had been previously reported only in East-Asian GWAS. Based on statistical evidence and linkage disequilibrium (LD) structure, we have curated and narrowed down the list of the most likely candidate causal variants for each region. Functional annotation using data from ENCODE filtered for PrCa cell lines and eQTL analysis demonstrated significant enrichment for overlap with bio-features within this set. By incorporating the novel risk variants identified here alongside the refined data for existing association signals, we estimate that these loci now explain ∼38.9% of the familial relative risk of PrCa, an 8.9% improvement over the previously reported GWAS tag SNPs. This suggests that a significant fraction of the heritability of PrCa may have been hidden during the discovery phase of GWAS, in particular due to the presence of multiple independent signals within the same regio

A Report of Industrial Test Services Under Compac Programme From April 2003 - March 2004

This report highlights the test services offered between April 2003 to March 2004 under the 'COMPAC' (Composite Product Development and Applications Centre) program to various industries engaged in plastics, fibre composites, carbon composite, adhesives, etc. It presents the range of materials tested and types of tests carried out as well as various industries served

Sandstones in the Coastal Area Between Visakhapatnam & Bhimunipatnam, East Coast of India

46-48The 2 highly ferruginous sandstone units found are elongate, parallel to the coast line and are unfossiliferous. The sandstones are coarse grained, well sorted and negatively skewed. Textural characters, areal pattern and mineralogical composition suggest that the sandstones have been derived from the eolian red sands and deposited during one of the sea level fluctuations on the east coast of India. The sandstones are considered to be post-pleistocene in age in view of their position above the late Pleistocene red sandy sediments

CONDITIONING AND QUALIFYING A MICROWAVE - BIT (BUILT IN TEST) UNIT FOR USE IN THE TARANG SYSTEM [END USER-IAF]

The Microwave component -BIT (Built In Test) unit was subjected to CATH test in a Combined Altitude, Temperature and Humidity chamber. This unit was developed by M/s FLIC Microwaves Pvt Ltd, Hyderabad for BEL, Bangdore for use in Tarang Systems. The CATH test was done per MIL-STD 810F, Method 500.4 for acceptance by end user. While conditioning, the functional test (perform Frequency generation and Power Output measurements) was carried out by the firm and the unit was handed over to the firm

Environmental Conditioning Composites and Components for Aerospace and Allied Fields.

The UPS and Grinder Units were subjected to low temperature test (i.e - 30°C/16hrs) in a low temperature/humidity chamber. After conditioning the units were handed over to the firm (i.e M/s Flotech Engineering Pvt Ltd for functional test. The smart Fatigue Meter unit were subjected to high temperature (i.e + 70°C/3hrs), low temperature (i.e - 40°C/4hrs) and thermal shock test (i.e - 40°C/1hr and + 70°C/l hr) in a temperature /humidity chamber. After conditioning the functional test was carried out by the ALD division, NAL. This document mainly brings out the details of the component /test specimens I conditioned and their test result
