Musculoskeletal disorders are one of the most commonly occurring life style related disease which significantly affect the quality of life. Other than age, body mass, nutritional factors and joint injuries, the occupation related stress and load also have substantial effect of this disease. In the present paper we have conducted a survey on Musculoskeletal diseases among academicians of our college and presented the results after statistical analysis. A Nordic based questionnaire modified suitably for this study was used. The results suggested a higher prevalence of neck and lower back pain among all faculties. The correlation studies suggested a higher positive relationship between joint pain and professional factors like prolonged standing, long term use of computers etc, which was even higher than effect of age and body weight.

This paper presents a comparative performance analysis of a single-stage GaAs Low-Noise Power Amplifier (LNPA) fabricated in a 0.25 µm pHEMT process to mitigate co-site interference across multiple frequencies in the L-and S-bands. We compare five different designs from 1.2 to 3.8 GHz, each offering a minimum bandwidth of 300 MHz. Designed bandwidth is sufficient to cover several popular 5G NR FR1 channels as well as suitable for carrier aggregation in the LTE bands. An Output 1-dB compression point (OP 1dB ) of 27.5 dBm, noise figure (NF) below 1 dB and an Output 3 rd -order Intercept Point (OIP3) up to 40 dBm is achieved. Adjacent Channel Leakage Ratio (ACLR) measurements are performed at 2.5 GHz with a Peak to Average Power Ratio (PAPR) of 11.8 dB. We achieve an ACLR of -25 dBc at 25 dBm of output power for a 20 MHz, 16-QAM modulation signal, while the corresponding power added efficiency & Drain-efficiency (DE) are, on average, more than 47% & 50% respectively. An integrated Electro-Static-Discharge (ESD) limiter is also incorporated, which can tolerate up to 350 V Human Body Model (HBM) and 125 V Charged Device Model (CDM) without failure. The design occupies a footprint of only 0.325mm 2 .

Aim: The aim of this study was to compare 2 mm conventional miniplates with three-dimensional (3D) strut plates in the treatment of mandibular fractures treated in the Department of Oral and Maxillofacial Surgery of a college in India, during 2012–2015. Materials and Methods: All 20 patients with mandible fracture requiring open reduction and internal fixation of the fracture were reported and reviewed in the Department of Oral and Maxillofacial Surgery of the same dental college in India, during 2012–2015. We classified the data according to the gender, age, etiology, fracture site, and method of treatment of the fractures. Fixation done in 10 patients with 2 mm conventional miniplates kept in Group I, while 10 patients with 3D strut miniplate system considered in Group II. Results: Assessment of patient was done under the following parameters with follow-up at regular intervals at 2 nd day postoperatively and at 1 st , 3 rd , and 6 th weeks postoperatively: pain, swelling, infection, interincisal mouth opening in millimeters, paresthesia/anesthesia, mobility between fracture fragments, overall occlusion, need for any supplemental fixation, fate of implant, and complications. Conclusions: 3D titanium miniplates showed similar results when compared to standard titanium miniplates with advantages such as reduction in operative time, ease of placement, and cost-effective over the conventional plate system.
