Analysis of Critical Success Factors In Application of “DRYWALL” Technique in Construction Industry

A drywall is a high-performance lightweight interior wall system consisting of a GI steel frame, encased in gypsum plasterboard on either side attached with self drilling drywall screws. The joints are then tapped and finished with gypsum jointing compounds. Drywall can be built three to four times faster than conventional masonry (brick/block) walls. Drywall name implies it is a water free process and hence can be put up much faster. Drywall is easy to put up and need less labour. Drywalls are eight to ten times lighter than masonry walls, reducing the dead load. This assumes significance in high-rise structures, resulting in not only structural cost saving, but a reduction in the burden of moving up material. By using qualitative research methodology & by studying on the project VOYAGE to the stars by cloud9 of acropolis Purple developers luxury residential project located in Sr no 43/44, NIBM Road, Pune 411060, India Website: wwwcloud9estate.in as my case syudy I had collected the required data. This assumes significance in high-rise structures, resulting in not only structural cost saving, but a reduction in the burden of moving up material. Studies have shown that drywall leads to structural cost saving of as much as 15%. Drywall is made of gypsum plasterboard, which is 100% recyclable hence gives green construction. Drywalls are also water free, thus saving precious natural resources. Plasterboard Steel Stud Partition Systems are designed for use in both non fire-rated and fire-rated applications.

DEVELOPMENT AND VALIDATION OF SPECTROPHOTOMETRIC AND ION PAIR CHROMATOGRAPHIC TECHNIQUE FOR ESTIMATION OF VALSARTAN AND HYDROCHLOROTHIAZIDE

Two new simple, sensitive, rapid, accurate and reproducible methods (UV-spectrophotometric and ion pair chromatography) have been developed for simultaneous estimation of valsartan (VAL) and hydrochlrothiazide (HCTZ) from their tablet dosage form. The first method involves multiwavelength spectrophotometric method (Method 1) in which interference of HCTZ at 245nm (wavelength for estimation of VAL) was removed by recording absorbance difference at 245nm and 301 nm whereas HCTZ was estimated directly from its absorbance at 316 nm at which VAL shows no absorbance. Linearity of the response was demonstrated by VAL in the concentration range of 5-45 g/ml with a square correlation coefficient (r2) of 0.9998. Linearity of the response was demonstrated by HCTZ in the concentration range of 2-18 g/ml with a square correlation coefficient (r2) of 0.9994. The second method utilizes ion pair chromatography (Method 2) on a HIQ sil ODS column (250 mm* 4.6 mm i.d.) using methanol: 0.0025 M orthophosphoric acid: (70:30 by volume) having pH 4.6: 0.1% hexane sulphonic acid as mobile phase with UV detection at 259nm over concentration range for VAL is 240-0 μg/ml, and for HCTZ is 75-0μg/ml. Losartan potassium was used as the internal standard. The suggested procedures were checked using laboratory prepared mixtures and were applied successfully for the analysis of their tablet dosage form. The results of analysis were statistically analysed. Both the methods were validated as per ICH Q2B guideline

Importance of urine sodium dithionite test in paraquat poisoning: a case study

Suicidal tendencies are one of the major social problems worldwide. It is equally seen in Indian population. Organo-phosphorus compounds are usually preferred because of their easy availability. Paraquat is one of the lesser known herbicide agent, which is not an OP compound. It is highly toxic and causes damage to the lungs, liver and kidneys. Occurrence of paraquat poisoning is rare, but has very high mortality rate. Here we report one such case which was earlier misdiagnosed as organo-phosphorus poisoning, but diagnosed later by qualitative urine sodium dithionite test. It is a simple test for early diagnosis of paraquat poisoning. It is recommended to performing this test in all suspected cases of oral poisoning

A case of fracture talus with medial malleolus treated with headless screws and cancellous cannulated screws using single anteromedial approach

Talar fractures are complex injuries with an array of management options and complications. We present a case of talar fracture with medial malleolus fracture fixed via common anteromedial approach through the fracture site. The incidence of associated malleolar injury has ranged from 19% to 28% in prior studies. The skin condition is often poor and prone to swelling in such cases which makes the management challenging. Along with poor wound healing, joint stiffness, osteonecrosis and osteoarthritis of the ankle are complications affecting the outcome of the patient

Oxidative stress versus inflammation, a better predictor of cardiovascular disease risk in polycystic ovary syndrome

Background: Polycystic ovary syndrome (PCOS) is also known as hyperandrogenic anovulation (HA) or Stein-Leventhal syndrome. PCOS has a diverse range of causes that are not entirely understood, but there is evidence that it is largely a genetic disease. Aim of the study was to evaluate better predictor of cardiovascular disease risk in women with polycystic ovary syndrome.Methods: 50 diagnosed patients of PCOS and 50 age matched healthy females were included in this study. Cases were diagnosed based on new Rotterdam criteria formulated by the American Society for Reproductive Medicine (ASRM). Fasting Blood samples were collected. Serum High sensitivity-C reactive protein (hs-CRP) and Malondialdehyde (MDA) were estimated.Results: Results were analyzed using unpaired t-test and p-value was calculated. Statistically non-significant increased levels of serum hs-CRP in PCOS cases as compared with controls were observed. MDA was found to be significantly increased in cases as compared to controls. ROC curve analysis shows MDA as a more specific predictor of cardiovascular disease risk in PCOS compared to hs-CRP.Conclusions: Increase in the serum MDA level indicates increased formation of reactive oxygen species and lipid peroxidation which leads to increased oxidative stress and this may increase cardiovascular disease risk in PCOS. hs-CRP a marker of chronic inflammation was not significantly increased in PCOS

Detonating Cord for Flux Compression Generation using Electrical Detonator No. 33

The paper highlights the use of electrical detonators for magnetic flux compression generator applications which requires synchronisation of two events with precise time delay of tens of ms and jitter within a few ms. These requirements are generally achieved by exploding bridge wire type detonators which are difficult to develop and are not commercially available. A technique has been developed using commercially available electrical detonator no. 33 to synchronise between peak of seed current in stator coil and detonation of explosive charge in armature. In present experiments, electrical signal generated by self-shorting pin due to bursting of electrical detonator has been used to trigger the capacitor discharge and the detonating cord of known length has been used to incorporate predetermined delay to synchronise the events. It has been demonstrated that using electrical detonator and known length of detonating cord, the two events can be synchronised with predetermined delay between 31 and 251 ms with variation of ± 0.5ms. The technique developed is suitable for defence applications like generation of high power microwaves using explosive driven magnetic flux compression generators.Defence Science Journal, 2011, 61(1), pp.19-24, DOI:http://dx.doi.org/10.14429/dsj.61.3

Ultrafast optical generation of coherent phonons in CdTe1-xSex quantum dots

We report on the impulsive generation of coherent optical phonons in CdTe0.68Se0.32 nanocrystallites embedded in a glass matrix. Pump probe experiments using femtosecond laser pulses were performed by tuning the laser central energy to resonate with the absorption edge of the nanocrystals. We identify two longitudinal optical phonons, one longitudinal acoustic phonon and a fourth mode of a mixed longitudinal-transverse nature. The amplitude of the optical phonons as a function of the laser central energy exhibits a resonance that is well described by a model based on impulsive stimulated Raman scattering. The phases of the coherent phonons reveal coupling between different modes. At low power density excitations, the frequency of the optical coherent phonons deviates from values obtained from spontaneous Raman scattering. This behavior is ascribed to the presence of electronic impurity states which modify the nanocrystal dielectric function and, thereby, the frequency of the infrared-active phonons

Swift Heavy Ion Induced Modification Studies of C60 Thin Films

Modification induced by 110 MeV Ni ion irradiated thin film samples of C60 on Si and quartz substrates were studied at various fluences. The pristine and irradiated samples were investigated using Raman spectroscopy, electrical conductivity and optical absorption spectroscopy. The Raman data and band gap measurements indicate that swift ions at low fluences result in formations that involve multiple molecular units like dimer or polymer. High fluence irradiation resulted in sub-molecular formations and amorphous semiconducting carbon, indicating overall damage of the fullerene molecules. These sub-molecular units have been identified with nanocrystalline diamond and nanocrystalline graphite like formations.Comment: 7 pages, 29 references and 9 figures submitted to J. Appl. Phy
