Rectification in Discharge Tubes

A detailed study of rectification phenomena in air following the earlier work of Chiplonkar is given. The effect in hydrogen and CO is also discussed. Recently Mr. Chiplonkar (1939) has made some quantitative investigations of the well-known phenomenon of rectification in discharge tubes. His work was mainly confined to the study of the precise role of the electrodes, their relative sizes and the inter-electrode distance in determining the rectification effect. This paper is an extension of Mr. Chiplonkar's work and deals with a detailed study of rectification phenomena in air. The effect in hydrogen and CO has also been partly studied

Chemical synthesis and study of structural and optoelectronic properties of CdS thin films: Effect of SILAR growth cycles

CdS thin films were deposited on glass substrates by using successive ionic layer adsorption and reaction (SILAR) method at room temperature. The effect of SILAR growth cycles on structural, morphological, optical and electrical properties of the films has been studied. The thickness of the deposited film is measured by employing weight difference method. The X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM) studies showed that all the films exhibit polycrystalline nature and are covered well with glass substrates. The values of average crystallite size were found to be 53 nm, 58 nm, 63 nm and 71 nm corresponding to the thin films deposited with 30, 40, 50 and 60 SILAR growth cycles respectively. From the UV–VIS spectra of the deposited thin films, it was seen that both the absorption properties and energy bandgap of the films changes with increasing number of SILAR growth cycles. A decrease of electrical resistivity has been observed with increasing SILAR growth cycles. &nbsp

Combined protein C and protein S deficiency with pregnancy

A 35 year old female patient, married since 8 years, G6P1L1SA4 was registered with our unit since 8th week of gestation. She was a known case of protein C and protein S deficiency diagnosed 7 years ago (thrombotic profile- protein C: 70% normal: 70-100%, protein S: 55% normal: 70/140%, AT-III: 116% normal 70/140%, factor V leiden: no mutation detected) which was detected on evaluation for her bad obstetric history. ACLA was also positive. She was started on injection low molecular weight heparin 0.6 mg s/c OD, in addition to continuing Tb. Aspirin 75 mg which had been started when the pregnancy was registered. Foleys induction was done at 39 weeks of gestation in view of previous LSCS with pre-eclampsia. Emergency LSCS was done in view of previous LSCS with non-progress of labour. Male child weighing 2.4 kg was born which is doing well. A patient having combined deficiency of both factors protein C and protein S is very rare. Anticoagulation therapy is the cornerstone in the management of patients with inherited coagulation defects

Acute and subchronic toxicity study of Tamra Bhasma (incinerated copper) prepared with and without Amritikarana

AbstractBackgroundTamra Bhasma (TB) is one among herbo-metallic preparations extensively used in routine ayurvedic practice. In the present era, Bhasma preparations used in ayurvedic system of medicines are always under stern observations for containing heavy metals which may raise the question of safety aspect.ObjectiveIn the present study, TB prepared with and without Amritikarana was subjected to toxicity study to ascertain the role of Amritikarana on safety profile of TB in rats.Materials and methodsBoth the samples of TB were administered to rats for 28 consecutive days at the doses of 5.5, 27.5, and 55 mg/kg. The effects of both drugs were assessed on ponderal changes, hematological, serum biochemical, and histopathology of various organs.ResultsResults showed that both the samples of TB did not produce any sign and symptoms of toxicity at therapeutic dose level (5.5 mg/kg) and therapeutic equivalent dose (TED) × 5 (27.5 mg/kg) while at higher dose of TED × 10 (55 mg/kg) TB has mild toxicity in liver, kidney, heart, and thymus on repeated administration for 28 days in rats. The sample without Amritikarana has more magnitude of toxicity than the sample with Amritikarana.ConclusionFrom the present study, it is concluded that TB with Amritikarana was found to be relatively safer than TB without Amritikarana at different dose levels in rats and hence suggest for safely use in humans at therapeutic dose level. It proves the role of Amritikarana in the preparation of TB

A prospective observational study of foetal outcome in twin pregnancy delivering at a tertiary health care center of South Gujarat

Background: Worldwide increased incidence of twin gestation. The rates of twin gestation have a direct effect on the rates of preterm birth and its co-morbidities. Importantly, this increased risk applies to each fetus and is not simply the result of more foetuses.Methods: This prospective study was carried out in department of obstetrics and gynaecology. 100 consecutive subjects fulfilling inclusion criteria   admitted to labour room and obstetrics intensive care enrolled over a period of around 1 year.Results: In this study twin delivery accounted for 1.3% of all delivery at our institute. On analysing neonatal morbidities Prematurity was commonest 65%, VLBW (23% first twin, 30% second twin), RDS (9% first twin, 13% second twin), birth asphyxia (7% first twin, 12% second twin), neonatal hyperbilirubinemia (7% first twin, 8% second twin). 34% of first twin and 40% of second twin required NICU admission. Early neonatal death observed in 6% of first twin and 8% of second twin. It was observed that proportion of neonatal complications was more in MCDA as compared to DCDA and in un-booked subjects as compared to booked subjects. This difference is statistically significant among both twin (p value<0.05).Conclusions: Twin pregnancy is associated with high perinatal morbidity. Specialized obstetrics and Intensive Neonatal care can decrease neonatal morbidity and mortality in twin gestation. We need to be extra vigilant in monochorionic twins and twin pregnancy with inadequate antenatal care

Relativistic calculations of the lifetimes and hyperfine structure constants in 67^{67}Zn+^{+}

This work presents accurate {\it ab initio} determination of the magnetic dipole (M1) and electric quadrupole (E2) hyperfine structure constants for the ground and a few low-lying excited states in $^{67}$Zn$^{+}$, which is one of the interesting systems in fundamental physics. The coupled-cluster (CC) theory within the relativistic framework has been used here in this calculations. Long standing demands for a relativistic and highly correlated calculations like CC can be able to resolve the disagreements among the lifetime estimations reported previously for a few low-lying states of Zn$^{+}$. The role of different electron correlation effects in the determination of these quantities are discussed and their contributions are presented.Comment: 9 pages, 1 figure. submitted to J. Phys.

Phenomenological BCS theory of the high-TcT_c cuprates

A BCS model characterized by a phenomenological pair potential with on-site ($V_0$), nearest ($V_1$), and next nearest ($V_2$) neighbour coupling constants, and an empirical quasiparticle dispersion taken from angle-resolved photoemission spectra is considered. The model can consistently explain the experimental data concerning the pair state of the hole doped cuprates. Three ingredients are required to make the interpretation possible: the existence of flat bands, a very small effective on-site repulsion, and a slightly dominating effective nnn attraction $V_2$ of the order of 60-80meV with a ratio $V_2/V_1 \approx 1.5$.Comment: 13 pages, uuencoded Postscrip

Development of Internet of Things (IoT) Based Monitoring of Hazardous Exhaust Compounds in Air - A Review

Presence of pollutants in Air is the most prominent problem globally confronted now a day. The extreme use of fueled vehicles and rapid urbanization has deteriorated the air quality. This deteriorated air contains hazardous compounds like Mono-oxides & Di-oxides of carbon, Sulphur, Nitrogen, Atmospheric Particulate Matter. Exposure to such hazardous compounds in the air for a long time can cause damage to the human health. Traditional air monitoring systems consists of monitoring stations. As far as traditional air quality monitoring methods are concerned, they are highly expensive and requires a regular maintenance. Due to these limitations, these stations are deployed in small numbers and also it provides indicative values of the sensed data. This monitored data has low resolution and precision. This paper proposes framework for the development of smart and portable system using Internet of Things (IoT) for monitoring of hazardous exhaust compounds in the air using real time. This framework consists of different types of sensors and a controller that are used for monitoring and assessment of the air quality. Also it is used to check the presence of hazardous compounds emitted by different industries and share this data through IOT. The outcome of the proposed research work can be utilized by industries as well as by other agencies to carry out an audit of hazardous exhaust components present in air, so as to take necessary precautions and to save human

Gathered wild food plants among diverse religious groups in Jhelum District, Punjab, Pakistan

Recent ethnobotanical studies have raised the hypothesis that religious affiliation can, in certain circumstances, influence the evolution of the use of wild food plants, given that it shapes kinship relations and vertical transmission of traditional/local environmental knowledge. The local population living in Jhelum District, Punjab, Pakistan comprises very diverse religious and linguistic groups. A field study about the uses of wild food plants was conducted in the district. This field survey included 120 semi‐structured interviews in 27 villages, focusing on six religious groups (Sunni and Shia Muslims, Christians, Hindus, Sikhs, and Ahmadis). We documented a total of 77 wild food plants and one mushroom species which were used by the local population mainly as cooked vegetables and raw snacks. The cross‐religious comparison among six groups showed a high homogeneity of use among two Muslim groups (Shias and Sunnis), while the other four religious groups showed less extensive, yet diverse uses, staying within the variety of taxa used by Islamic groups. No specific plant cultural markers (i.e., plants gathered only by one community) could be identified, although there were a limited number of group‐specific uses of the shared plants. Moreover, the field study showed erosion of the knowledge among the non‐Muslim groups, which were more engaged in urban occupations and possibly underwent stronger cultural adaption to a modern lifestyle. The recorded traditional knowledge could be used to guide future development programs aimed at fostering food security and the valorization of the local bio‐cultural heritage
