Pneumonitis following diesel fuel siphonage

AbstractPetroleum diesel is a complex mixture of liquid hydrocarbons and mainly used as fuel in transport vehicles. The practice of manual siphoning of diesel from fuel tanks is common in developing countries but hydrocarbon pneumonitis due to diesel siphonage is rarely reported. We report pneumonitis following diesel fuel siphonage in a 30-year-old driver. Initially patient had severe nausea and vomiting followed by chest pain and breathlessness after three days. In our case, induced sputum was diagnostic as against majority of cases where bronchoscopy was used as diagnostic tool. Recovery was complete with medical treatment

Misplaced IUCD: a case report

Contraception is a national emergency, essential in a developing country like India. Intrauterine contraceptive devices (IUCDs) are amongst the most frequently used methods of contraception. The patients with misplaced IUCDs may present with pregnancies or ‘lost strings’ or they may remain asymptomatic and/ or may have recurrent pregnancy losses and may become pregnant as in our case

Traditional technological aspects of fishing crafts in North Coastal Andhra Pradesh, East Coast of India

The study focuses on different types of boats used in marine fishing by traditional communities inhabiting the northeast coastal Andhra Pradesh. These boats area grouped into tied, stitched and moulded. A few of these prototypes of mechanised boats are added by mechanical devices. All these boats are fabricated by indigenous technologies by using local materials. The fabricators are illiterate fishing people. Their ingenuity of maintaining ratios in relation to keel, stem, hull, mast and rudder of a boat to navigate on open sea is astonishing. Further, the study discusses different types of nets used in harvesting various types of fish. The other fishing paraphernalia like hooks, lines, lures etc are also discussed

Analysis of the nutritive composition of wild and farmed tiger shrimp Penaeus monodon fabricius

The present study was undertaken to estimate and compare the nutritive value (moisture, protein, fat, carbohydrate, calcium, phosphorus, iron) of peeled tails of wild and farmed shrimp Penaeus monodon as there is a misnomer that farmed shrimp has high fat/cholesterol content compare to wild shrimp and also wild shrimp is highly nutritious than farmed tiger shrimp. The percentage moisture content in the peeled tails of tiger shrimp specimens collected from coastal waters varied from 73% to 76.74% with an average of 74.83 %, protein content ranged between 19.5% and 21.0% with an average of 20.17%. The fat content varied from 3.2% to 5.0% with an average to 4.06%, carbohydrate content ranged between 0.07% and 1.09% with an average of to 0.64% and ash content varied between 0.43% and 0.55% with an average of 0.49 %. The phosphorus (as phosphate) content ranged from 923 to 1407 and averaged 1272 mg/l00g. The iron (ppm) concentration fluctuated between 79.61 and 93.19 and averaged to 89.04 ppm. From Brackish waters the percentage of moisture content ranged from 73.84 % to 76.14 % and averaged to 75.36%, percentage protein content varied from 18.1% to 20.1% and averaged to 19.05%. The percentage fat content varied from 3.09% to 5.44% and averaged to 4.06%, percentage carbohydrate content varied from 0.29% to 1.79% and averaged to 0.94% and ash content fluctuated from 0.45% to 2.74% and averaged to 1.01%. The phosphorus content ranged between 747 and 1025 and averaged to 888 mg/l00g and calcium content ranged between 186 and 501 and averaged to 375 mg/l00g. Iron concentration varied between 82.01 and 112.06 ppm and averaged to 100.45 mg/l00g

Structural, Morphological and 1/f noise Properties of ITO/TiO2 thin Films by e-beam Evaporation System for Optoelectronic Device Applications

In the present research study, ITO/TiO2 thin films were prepared on a glass substrate by using an electron beam (e-beam) evaporation system at different annealing temperatures (300, 350, 400 and 450 °C). The amorphous and crystalline natures of ITO/TiO2 structure were analyzed by X-ray diffraction study. As the grain size becomes larger, indirectly it will develop the crystalline quality of the TiO2 films studied from AFM. The surface of TiO2 films and the crystalline size of the sample were increased gradually with respect to a temperature that is observed in SEM. The elemental composition determined by the energy dispersive analysis of EDAX showed that TiO2 thin films were highly stoichiometric. Further, the higher optical transmittance (93%) was obtained with 450 °C annealed ITO/TiO2 film. The optical band gap increased along with annealing temperatures (300, 350, 400 and 450 °C). All the above results of this present work can be utilized for solar cell and optoelectronic device applications. © 2020 Author(s)

Tensile testing of cellulose based natural fibers for structural composite applications

A series of tensile tests were conducted on a Lloyd LRX tensile testing machine for numerous natural fibers deemed potential candidates for development in composite applications. The tensile tests were conducted on the fibers jute, kenaf, flax, abaca, sisal, hemp, and coir for samples exposed to moisture conditions of (1) room temperature and humidity, (2) 65% moisture content, (3) 90% moisture content, and (4) soaked fiber. These seven fibers were then tested for the four conditions and the mechanical properties of tensile strength, tensile strain to failure, and Young's modulus were calculated for the results. These results were then compared and verified with those from the literature, with some of the fibers showing distinctly promising potential. Additionally, a study on the effect of alkalization using 3% NaOH solution was carried out on flax, kenaf, abaca, and sisal to observe impact that this common fiber pre-treatment process has on fiber mechanical properties. The result of the investigation indicated that over treatment of natural fibers using NaOH could have a negative effect on the base fiber properties. It is consequently apparent that a treatment time of less than 10 min is sufficient to remove hemicelluloses and to give the optimum effect

HPLC-LIF for early detection of oral cancer

At present, the diagnosis of many cancers relies on the subjective interpretation of morphological changes in biopsy samples. This usually provides only late diagnosis. Early detection, which can provide more successful therapy, is expected to be possible by identification of tumour markers in physiological samples. Immunoassay used at present for this purpose has several drawbacks. It is applicable only for known markers, can usually detect only one marker at a time, and may also fail to detect a marker when there exist conditions, which may mask or prevent the interaction between antigen and the antibody. We have developed a high performance liquid chromatography- laser induced fluorescence (HPLC-LIF) technique to detect and record simultaneously spectra and chromatograms of physiological samples, which will enable the detection of multiple 'markers' in a single physiological sample in a short time. Samples of saliva and serum from normal and oral cancer subjects have been studied with the set up. The present studies show that body fluids like saliva and serum of normal, premalignant and malignant subjects have substantially different protein profiles. By simultaneous recording of the chromatographic peaks and corresponding fluorescence spectra, it is possible to carry out unambiguous discrimination between normal, premalignant and malignant cases even when markers are present in femto/subfemtomole quantities, which should assist in early diagnosis of neoplasia
