SummaryThe chemical analyses, structural formulae, and optical data of seven orthopyroxenes and six clinopyroxenes, all from the charnockite series of Amaravathi, are presented. The orthopyroxenes are in the hypersthene-ferrohypersthene range while the clinopyroxenes are in the sahlite range. The aluminous nature of the pyroxene is believed to be the result of high pressure. The clinopyroxenes have the granulite trend on the Wo-En-Fs plot. The tie-line projections and the KD values for the pyroxene pairs indicate conditions of chemical equilibrium around 670 °C for the charnockite series of Amaravathi.

Igneous Origin

SummaryThe potash feldspar in the charnockites is orthoclase and they are inferred to have been formed around 700 °C. A twin-law study of the plagioclase indicates an igneous origin of the charnockites and pyroxene granulites. The KD values of the coexisting pyroxenes in the granulites are appropriate to equilibrium at 670 °C. A substantial substitution of A1 for Si in the values of the coexisting pyroxenes in the granulites are appropriate to equilibrium at 670 °C. A substantial substitution of A1 for Si in the Z group in all mafic minerals studied also indicates relatively high temperatures of formation. Almandine is pyroperich, a result of high pressure. The charnockites and pyroxene granulites are inferred to be formed under conditions of high pressure and temperature.

SummaryChemical analyses, optical data, and cell parameters are given for olivine (Fo90·3 and Fo91·4), orthopyroxene (Ca1·5Mg89·0Fe9·5 and Ca9·8Mg88·6Fe10·6), clinopyroxene (Ca39·6Mg55·8Fe4·6), and chromian spinel from olivine nodules from the Carboniferous basalt of Calton Hill, Derbyshire. Chemical and modal analyses of the nodules and of their host rock are also presented. The distribution of Mg and Fe in the coexisting pyroxenes is fairly similar to that observed by Ross, Foster, and Myers (1954) but differs slightly in that the extension of the pyroxene tie-line intersects the Ca-Mg side of the Ca-Mg-Fe triangle. The clinopyroxene is a normal augite rather than the hydrous augite previously reported (Tomkeieff, 1928). The high chromium content of the spinel and clinopyroxene contrasts with the low value for this element in the host rock, suggesting that these minerals are not differentiates of the basaltic magma: the nodules are considered to represent fragments from a deep-seated peridotite.

SummaryThe chemical analyses, structural formulae, and trace element data are presented for 18 orthopyroxenes and 9 clinopyroxenes from the charnockitie rocks of Kondapalli, Andhra Pradesh, India. The chemistry of these pyroxenes is discussed and conclusions are drawn. The data are compared with the similar data available for the pyroxenes of the charnockites of the type area near Madras, some 200 miles south of Kondapalli. The element-distributional relationships between the coexisting pyroxenes are discussed and inferences are made regarding the temperature of crystallization of charnockite pyroxenes.

ObjectivesTo explore associations of night-time light intensity (NTLI), a novel proxy for continuous urbanisation levels, with mean systolic blood pressure (SBP), body mass index (BMI), fasting serum low-density lipoprotein (LDL) and fasting plasma glucose (FPG), among adults in early-stage urbanisation in Telangana, South India.DesignCross-sectional analysis of the third wave of the Andhra Pradesh Children and Parents Study cohort.Setting28 villages representing a continuum of urbanisation levels, ranging from rural settlement to medium-sized town in Telangana, South India.ParticipantsData were available from 6944 participants, 6236 of whom were eligible after excluding pregnant women, participants younger than 18 years of age and participants missing data for age. Participants were excluded if they did not provide fasting blood samples, had implausible or missing outcome values, were medicated for hypertension or diabetes or had triglyceride levels invalidating derived LDL. The analysis included 5924 participants for BMI, 5752 participants for SBP, 5287 participants for LDL and 5328 participants for FPG.ResultsIncreasing NTLI was positively associated with mean BMI, SBP and LDL but not FPG. Adjusted mean differences across the range of village-level NTLI were 1.0 kg/m2 (95% CI 0.01 to 1.9) for BMI; 4.2 mm Hg (95% CI 1.0 to 7.4) for SBP; 0.3 mmol/L (95% CI −0.01 to 0.7) for LDL; and −0.01 mmol/L (95% CI −0.4 to 0.4) for FPG. Associations of NTLI with BMI and SBP were stronger in older age groups.ConclusionThe association of NTLI with cardiovascular disease (CVD) risk factors identify NTLI as a potentially important tool for exploring urbanisation-related health. Consistent associations of moderate increases in urbanisation levels with important CVD risk factors warrant prevention strategies to curb expected large public health impacts from continued and rapid urbanisation in India.

Study Results

BACKGROUND: The majority of handicraft workers in India falls under the informal sector, which plays a prominent role in the employment generation. Artisans in handicraft sectors encounter various hazards and risks causing occupational diseases. OBJECTIVE: The key objective of the study is to identify the prevalence of musculoskeletal disorders and occupational risk factors among the artisans involved in making traditional lacquerware toys in Karnataka and Andhra Pradesh, South India. METHODS: The subjects considered in this study are 177 artisans who work in mechanized lathes at Channapatna of Karnataka and Etikoppaka of Andhra Pradesh, South India. The information regarding the reported work-related musculoskeletal disorders (WMSD) symptoms from 7 days to 12 months are collected through modified Standardized Nordic Questionnaire and by direct observations. Moreover, the intervention of WMSD in their day-to-day life and the overall comfort of their body are also determined. The questionnaire survey is conducted through face-to-face interviews and by direct field study. RESULTS: From the statistical analysis, it is found that about 76.83%of the study population (77.4%male and 74.28%female) has self-reported WMSDs. The prevalence of WMSD is most common in the age group of 30–40 years. Physical factors like workplace adaptability, stress at work, body postures, health status, body mass index, active and enough breaks during work and body condition at the end of work have a significant association with WMSD. CONCLUSION: In this study, many of the work-related and lifestyle/health-related factors show a significant association with WMSD in artisans. The sub-standard working environment and the nature of work expose artisans to many occupational risks in their day-to-day life. To mitigate the occupational risks and musculoskeletal disorders, the workspace needs to be resigned ergonomically.

Pterocarpus Santalinus

Background: Pterocarpus santalinus L.f. (Fam. Leguminosae) is a medium sized, deciduous tree distributed in South India mainly in Andhra Pradesh, Karnataka and Tamil Nadu. The heartwood is highly prized and medicinally useful. The heartwood is used in Indian system of medicine for leucorrhoea, piles, syphilis, vomiting, fever, thirst, purifying blood and in wound healing. Pterocarpus santalinus is one of the ingredients in many Siddha and Ayurvedic formulations namely Cintil Ney, Senchandana Manapagu, Candana Bala, Laksadi Taila and Candanadi lauha. Objective: The present study brings out macro-microscopic atlas on heartwood of medicinal plant Pterocarpus santalinus L.f. Materials and Methods: Sections and powder were observed and photographed under different magnifications with the help of Olympus BX51 Microscopic unit fitted with Olympus Camera. Results: Macroscopically colour, odour and taste; microscopically tyloses, needle eye end fibres, forked fibres with pegged and sharp end, pitted and border pitted vessels, uni-seriate medullary rays, Reddish brownish content, oil globules, simple starch grains, crystal fibres and prismatic crystals of calcium oxalate are the unique diagnostic characters reported. Conclusion: The finding of the present study is believed to be helpful in identifying the genuineness of the heartwood in crude raw drug and also in standardization of herbal formulation containing red sandalwood as ingredient.
