Cross-layer aware transport protocols for wireless networks
No full textThis dissertation addresses the problem of reliable file transfer over single-hop and multi-hop shared-media wireless networks which are generally characterized by fluctuating bandwidth and error characteristics. Traditional reliable file transport protocols such as TCP assume relatively slow-varying links and were not generally designed to deal with interference problems of shared media wireless networks. The large performance gap between unreliable UDP and reliable TCP motivates the investigation of new transport protocols that might achieve significantly faster file transfer than TCP on wireless media.
CLAP - a Cross Layer Aware transport Protocol has been developed as a general solution for reliable file transfer, with decoupled flow control and error control to accommodate time-varying links. Error control in CLAP was designed to minimize interference and round-trip time estimation. Flow control in the proposed transport protocol leverages MAC status information via a novel cross-layer software framework (CLF), developed to provide systematic access to intra-node and inter-node status information.
Single hop evaluations, which consider an 802.11b wireless LAN with wired backhaul, were carried out using both NS2 simulations and ORBIT test-bed experiments. In time-varying, high loss scenarios, TCP shuts down operation without MAC retries, while an early CLAP version (CLAP-beta) achieves over 68% of upper-bound UDP performance. In noise-free scenarios, a "skip-ACKs" TCP modification to reduce interference achieves limited gains since TCP flow control depends on regular ACKs, while CLAP-beta approaches peak UDP performance by fully using the bandwidth available.
Multi-hop evaluations with NS2 simulations consider a 3-hop primary path in a 4x4 wireless mesh over 802.11b single-channel interfaces. Occasional background flows and on-off channel noise injection produce bandwidth and error fluctuations. These simulations expose the general multi-hop wireless problem where self interference in the forward path significantly reduces end-to-end bandwidth. Increasing interference and random packet losses tend to degrade TCP performance even more significantly than in 1-hop scenarios. Here, CLAP-final with improvements (relative to CLAP-beta) to reduce dependence on RTT estimation achieves over 90% of UDP performance in a variety of time-varying conditions.
This thesis demonstrates the efficacy of reliable file transfer using CLAP to address interference and time-varying links in both single- and multi-hop wireless network scenarios. Future research opportunities include cross-layer techniques for error control, efficient inter-node protocols for CLF, and tighter integration with mesh network routing protocols.Ph.D.Includes bibliographical references (p. 108-113).by Sumathi Gopa

ASSOCIATION OF VITAMIN D DEFICIENCY WITH HYPERANDROGENISM IN FEMALES WITH POLYCYSTIC OVARIAN SYNDROME
No full textObjective: This study designed to assess the relationship of vitamin D status with clinical features of hyperandrogenism in the young unmarried females Study design: A case control study. The study was carried out in Gynecology and Obstetrics unit of Railway Hospital, Rawalpindi from Oct, 2014 to April, 2015. Materials and Methods: A sample of 100 diagnosed PCOS patients, age range 16-25 years with clinical features of hyperandrogenism were included in this study with their written consent. 25OH Vitamin D Total Elisa Kit was used to assess the levels of Vitamin D. The Data was analyzed by using SPSS version 21 and ANOVA test was used to assess the relationship. P value < 0.05 was considered significant. Results: Vitamin D levels were tested in PCOS patients presenting clinical features of hyperandrogenism and it is found that there is insignificant relationship present between severity of hypovitaminosis D and hirsutism (P=0.669), acne (P=0.480) and alopecia (P=0.317) among PCOS patients. Conclusion: Although hirsutisim presents itself as the most common feature in PCOS patients (51%), but no significant relationship is found between Hypovitaminosis D and clinical features of hyperandrogenism suggesting insignificant role of vitamin D in the pathogenesis of hyperandrogenism in PCOS patients.

Bone mineral density and its correlation with Vitamin D status in healthy adults of Manipur – A cross-sectional study
No full textThe levels of vitamin D have an important effect on bone mass in young and old. Hypovitaminosis D adversely affects calcium metabolism, osteoblastic activity, matrix ossification, bone remodeling, and hence bone density. Objective: The present study was conducted to determine the status of serum 25(OH)D and BMD of healthy adult men in Manipur and also to find out the relationship of 25(OH)D level with BMD. Methods: A cross-sectional study was conducted in Department of Physiology in collaboration with the Department of Physical Medicine & Rehabilitation, Regional Institute of Medical Sciences (RIMS), Imphal from October 2014 to September 2016. 100 Healthy adult males in Manipur in the age group 18-35years and ≥50years were included in the study after obtaining Ethical approval from the Research Ethics Board, RIMS, Imphal. The serum 25-OH vitamin D level was estimated by using an enzyme immunoassay (EIA) kit (IDS immunodiagnostic systems, United Kingdom). The BMD of lumbar spine was determined using enCORE – based X-ray bone densitometer (Lunar Prodigy advance, GE Medical Systems, USA) which is based on DEXA scan. Results: The present study revealed that the majority of subjects with insufficiency of 25(OH)D had low bone mass, whereas all the subjects with 25(OH)D deficiency had BMD readings consistent with osteopenia or osteoporosis in both the age groups. This study also showed a positive correlation between BMD and 25(OH)D in most subjects, particularly in the groups with insufficiency or deficiency of 25(OH)D.Conclusion: In conclusion, the study shows a positive relationship between the serum 25 (OH) D concentrations and BMD.

SUBLINGUAL VITAMIN D3 DRUG THERAPY IN VITAMIN D DEFICIENCY PATIENTS AT PRAVARA RURAL HOSPITAL
No full textThe present study was aimed to study the effect of Sublingual Vitamin D3 on Serum Vitamin D level in Vitamin D deficiency patients. This was a cross-sectional and interventional study. All the Vitamin D deficiency patients of age 18-60years and either gender, willing to participate in the study were included. Patients who had greater than 20 ng/ml were excluded from the study. The total number of participants in our study was 200, out of these 111 males and 89 females, the mean age in our study was 51.07 ± 7.39Yrs. All volunteers were given sublingual vitamin D3 (60,000IU) in six doses every fifteen days of follow up for 3 months. The subject’s serum 25(OH)D levels were estimated before and after the treatment of sublingual vitamin D3. There was a statistically significant difference in serum vitamin D3 level before 16.61±6.71 ng/ml and after 35.80±7.80 ng/ml after treatment with Sublingual Vitamin D3. Six doses of 60,000IU of Vitamin D3 sublingual route having improved the role of serum 25(OH)D levels in the treatment of Vitamin D3 deficiency patients.Keywords: Vitamin D3; Sublingual rout
