Present status of peanuts and progression in its processing and preservation techniques
No full textPeanut or groundnut is one of the major oilseed crops in the world. It is rich in oil and proteins. Developing countries account for about 95% of the world peanut production. Asia alone accounts for 70% of this amount where the major producers India and China together represent over two-third of global output. Traditionally, groundnuts are dried in open sun to its safe moisture level for storage. Natural and artificial (hot air drying) drying methods of groundnuts are being used throughout the world. Artificial peanuts drying devices consume very large amount of energy. In this paper, present status of peanut and a comprehensive review of its drying methods are discussed. Recent developments in preservation and storage of groundnuts are also highlighted
Indexing of Journals and Indices of Publications
No full textJournal indexes are indicators toward the quality of a journal. Authors, researchers, and the audience need some criteria to judge which literature they need to read or which journal they need to send their article to. Journal indexes help the respective groups to make this decision. From Index Medicus to Web of Science, journal indexes use different criteria to judge the quality of a journal or an article. Figures like impact factor and CiteScore also rank journals and articles based on various criteria so that the audience and authors can make their pick. Author indices like h-index and ResearchGate score aid in comparing scientific work done by authors and researchers. Indexes of journals, publications, and authors therefore offer a classification of medical literature from which the best can be chosen depending on the requirements in their respective fields
FORCED CONVECTION DRYING OF INDIAN GROUNDNUT: AN EXPERIMENTAL STUDY
No full textIn this paper, convective and evaporative heat transfer coefficients of the Indian groundnut were computed under indoor forced convection drying (IFCD) mode. The groundnuts were dried as a single thin layer with the help of a laboratory dryer till the optimum safe moisture storage level of 8 – 10%. The experimental data were used to determine the values of experimental constants C and n in the Nusselt number expression by a simple linear regression analysis and consequently, the convective heat transfer coefficient (CHTC) was determined. The values of CHTC were used to calculate the evaporative heat transfer coefficient (EHTC). The average values of CHTC and EHTC were found to be 2.48 W/m2 oC and 35.08 W/m2 oC, respectively. The experimental error in terms of percent uncertainty was also estimated. The experimental error in terms of percent uncertainty was found to be 42.55%. The error bars for convective and evaporative heat transfer coefficients are also shown for the groundnut drying under IFCD condition
Neuroimaging in pediatric seizures
No full textBackground: Accurate etiological diagnosis of seizures in children is important to begin an effective treatment. MRI is an excellent neuroimaging tool that is highly accurate. It helps in diagnosis, determining the treatment protocol and predicting the outcome. Dedicated studies in paediatric population using MRI brain have been even fewer till date in India. Current study aims to find the common etiology of pediatric seizures on MRI in a developing country like India.Methods: Hospital based retrospective study. 105 cases in age group between 0 months to 12 years. Seen between 2014 till date included in the study. All cases underwent MRI.Results: Most common imaging findings were inflammatory granuloma in 10 (9.5%). Other findings were- Hypoxic ischemic encephalopathy (HIE) in 5 (4.7%), cerebral atrophy in 2 (1.9%), focal dysmyelination in 3 (2.8%), calcifying granuloma in 3 (2.8%) and periventricular leucomalacia in 2 (1.9%). Uncommon findings were that of lissencephaly, dysgenesis of corpus callosum, mesial temporal sclerosis, AV malformation, periventricular hemorrhage, schizencephaly, abscess and infarction in one child each (0.9% each). 69 children had no abnormal findings in brain.Conclusions: The commonest etiology of seizures is inflammatory granuloma. Early recognition of potentially treatable diseases helps in timely treatment and arrest of progression of disease. It is highly recommended to use MRI as primary investigation for seizures. Every effort should be made to provide facility of MRI for management of seizures in all parts of India
Development of empirical expression for thin layer groundnut drying under open sun and forced convection modes
No full textThe thin layer drying behaviour of groundnut was investigated under open sun drying (OSD) and indoor forced convection drying (IFCD) modes. The groundnut samples were dried from initial moisture content of 38% (w.b.) to the safe storage moisture content of 8-10% (w.b.). Four mathematical models were compared for describing the groundnut drying process. The performance of thin layer drying models was investigated by comparing the statistical parameters such as coefficient of correlation (R), reduced chi-square (χ2), root mean square error (RMSE), and mean bias error (MBE) between experimental and predicted moisture ratios. Henderson and Pabis model was observed to give the highest value of R and lowest values of χ2, RMSE and MBE for the groundnut drying under both OSD and IFCD modes. The values of statistical parameters under Lewis model were also found to be very close to Henderson and Pabis model. Therefore, Henderson and Pabis and Lewis models were found to be the best for describing the drying behaviour of groundnut under both given conditions.
Utility of color Doppler in diagnosing ureteric calculi: a useful adjunct
No full textBackground: Renal colic is a common presenting complaint in patients report to the out patient department. Usually the first investigation these patients undergo is ultrasound because of its widespread availability. Using color Doppler to study the characteristics of urine jet emanating from the vesicoureteric junction might prove useful in improving the diagnostic accuracy of ultrasound in patients with suspected ureteric calculi.
Methods: All patients found to have unilateral ureteric calculi on non-enhanced computerized tomography between March 2015 to August 2016 were subject to sonographic assessment. Color Doppler interrogation was done to study the ureterovesical jet characteristics. The cut-off values for differences between obstructed and unobstructed side were calculated on the basis of Receiver Operating Characteristic (ROC) curve.
Results: A total of 67 patients conforming to our inclusion criteria were selected for the study. There were significant differences of jet frequency (P < 0.05), duration (P < 0.05) and peak velocity (P < 0.05) between obstructed and non-obstructed ureters. The cut-off values for these parameters based on our study population for ureterovesical jet frequency, uration and peak velocity were <1 jet per minute, <2.5 seconds and <7 cm/sec respectively. The combined sensitivity and specificity of these three parameters was calculated as 99.45% and of 99.99% respectively.
Conclusion: Flow dynamics studies of ureterovesical jet characteristics using color Doppler significantly increase the sensitivity and specificity of ultrasound for diagnosis of ureteric obstruction. It may be incorporated as an adjunct to gray-scale ultrasound in routine practice to improve accuracy

No full textA review on applications of greenhouse drying and its performance
No full textLimited sources and rising cost of fossil fuels has instigated researchers to look towards renewable energy resources. Among renewable energy resources, solar energy is required to become indispensable in the future, as it is inexpensive, abundant, inexhaustible, environmental friendly and non-pollutant. Most of the people living in developing countries are dependent on agriculture. Agricultural products are dried to increase the storage life, minimize the packaging requirement and reduce the transportation weight. Solar drying for drying agricultural products is being practiced since long back throughout the world. Because of its drawbacks, advance technique, i.e. greenhouse drying, is being adopted for drying crops to reduce the drying time and increase the quality of the food products. Some new methods have also been attempted to increase the drying efficiency of greenhouse. In this paper, a comprehensive review of greenhouse drying of various commodities is presented. Different parameters such as thermal analysis, drying characteristics of crops, energy and exergy analysis, and greenhouse drying performance were discussed. In addition, the economical aspects of greenhouse dryers were also highlighted. This review paper will be helpful to the new researchers to know about the various technical aspects of the greenhouse dryer.
