समुद्रातल्या पिंजऱ्यातली संगोपन मत्स्यशोति

For the grow-out trials, circular cages of diameter ranging from 6-15 meters have been tried by CMFRI. However, cage diameter 6-10 is recommended for the culture of Mullet, Cobia, Pompano, Sea bass and Pearl spot. The grow-out of candidate species in caged enclosures requires proper planning and management. The critical inputs like right kind of seed, nutritionally balanced feed and routine cage maintenance activity decide the success of grow-out production. Unlike closed or semi-closed culture systems, marine environment is more diverse and dynamic, thus did not offer much scope for the environmental as well as biological manipulations. After proper site selection and cage installations, cages should be stocked with recommended numbers of seed depending upon water volume/ cage area

Biochemcial Changes in Powery Mildew Infected Leaves of Abelmoschus esculentus

Four types of leaf samples A1, A2 , B1 and B2 were taken from healthy and infected plants; and their free amino acids, sugars and organic acid contents were analyzed chromatographically. In case of free amino acids lysine, arginine, asparatic acid, glutamic acid, glycine and phenylatanine were found in all. There was no qualitative difference except for lysine, which gets totally consumed during the course of pathogenesis. Quantitatively was a general increase in amino acid content in B1 sample. In all three sugars were detected, they were fructose, sucrose and raffinose in all the four sample. There was a gradual decrease in the concentration of fructose and sucrose during the pathogenesis. While raffinose was maximum A1 in sample. Organic acid detected in these samples were sebacic acid, adipic acid, succinic acid, maleic acid and citric acid. Succinic acid was totally missing in B2 sample. While adipic and citric acid were maximum in B2 sample. The maximum concentration of sebacic acid was A1 sample and was least in B2. The concentration of maleic acid was maximum in A2 sample

Man on a mission for waste to wealth transformation

Shri. Ramdas Tukaram Kokare, presently working as Chief Officer in Municipal Corporation, Karjat which has a total population of 30,000 and generates Class III Municipal Solid Waste (MSW) in the tune of 12 metric tonnes per day. Earlier during 2010 to 2015 he had served as Chief Officer at Municipal Corporation Dapoli, Maharashtra and during 2015-2017 he at Vengurla also in Maharashtra. In 2010, Shri Ramdas came up with the idea of waste management at the source level and decided to segregate plastic waste into recyclable and non-recyclable categories. Plastic carry bags of less than 50 micron thickness were in the non-recyclable category, while bottles, packaging material of food items and wrappers were to be recycled for further usage. Local self-help groups were roped in to produce paper bags and some awareness campaigns were organized

Numerical investigation of oil injection in a Roots blower operated as expander

The adoption of positive displacement machines as expanders in Organic Rankine Cycles (ORCs) is increasingly common, especially in the low to medium power range. At the same time, these devices often serve as compressor in Vapor-Compression Refrigeration Systems. In both cases, the application of Computation Fluid Dynamics (CFD) to optimize such machines has become an integrated tool in the design process. As a consequence, several challenges associated with the numerical simulation have to be taken into account. For example, the modeling of the gap represents a challenge for the stability of the numerical analysis. The dynamic of the process, combined with deformations of the clearances and of the working chamber has to be considered with extra care. To raise the efficiency of the machine, oil is typically injected. Its numerical modeling imply an extra challenge in the simulation of the actual operation of the machine. The present work is mainly focused on the multi-phase nature of the flow, with a particular analysis of the lubricant oil injected. In this work, a two-lobe Roots blower operated as expander has been simulated with the open-source software OpenFOAM-v1812, using the SCORG-V5.2.2. This analysis highlights the areas that are affected the most by the oil presence in order to highlight the sealing effect it provides

Luteoma in pregnancy: a rare cause of threatened preterm labour!

Pregnancy luteoma is a rare non-neoplastic tumor-like mass of the ovary. They are usually asymptomatic and found incidentally during ultrasound imaging or surgery. Rarely do they present with pain abdomen mimicking threatened preterm labor. They regress spontaneously after delivery. We presented a case of a 29-year-old G4A3 with twin pregnancies and chronic hypertension who presented with acute flank pain, constipation, and occasional hardening of the uterus. A provisional diagnosis threatened preterm labor with suspected ureteric colic and cystitis was made. The patient was initially managed on the same line but on a detailed in-patient evaluation her ultrasound revealed bilateral multicystic ovaries with few hypoechoic areas inside it mostly suggestive of ‘luteoma of pregnancy’. The patient had acne, hirsutism, and chronic hypertension well controlled on antihypertensives. The patient delivered twins successfully by cesarean section and luteoma and symptoms were resolved postpartum after 4 months. Recognition of this entity is important so that malignancy can be ruled out and unnecessary surgery, with concomitant risk to both the mother and the fetus, is avoided

A successful outcome of pregnancy with Berger disease

With the increasing prevalence of chronic kidney disease (CKD) in the general population, female patients of fertile age with impaired kidney function are becoming more common. The presence of CKD in pregnant patients has been associated with poorer pregnancy outcomes. IgA nephropathy is the most common glomerulonephritis worldwide. The outcome of pregnancy in patients with CKD is related to impaired glomerular filtration rate and the degree of proteinuria. In non-aggressive IgA nephropathy, there is traditionally a slow progression to chronic kidney failure in 25–30% of cases during a period of 20 years. Women with immunoglobulin g A nephropathy (IgAN) are at higher risk of hypertension, preeclampsia, and fetal loss; the prognosis is worse for those who have advanced chronic kidney disease and proteinuria. Here we present two case reports who successfully delivered having aggressive IgA nephropathy and chronic hypertension in pregnancy.

Caesarean section under spinal and epidural anesthesia in complete atrioventricular block without a pacemaker: a rare case report

Complete heart block (CHB) during pregnancy is rarely encountered. Management requires a multidisciplinary approach involving the obstetrician, cardiologist, anesthetist, and neonatologist. Treatment varies from medical management to temporary or permanent pacemaker insertion. Complete atrioventricular block comprises complete absence of AV conduction - none of the supraventricular impulses are conducted to the ventricles. Perfusing rhythm is maintained by a junctional or ventricular escape rhythm. Typically, the patient will have severe bradycardia with independent atrial and ventricular rates. The incidence is 1 in 15,000 to 20,000 live births. We successfully managed caesarean section in a pregnancy with complete atrioventricular block under spinal and epidural anesthesia without a pacemaker. Asymptomatic pregnant women with congenital complete atrioventricular block can tolerate caesarean section under spinal and epidural anesthesia without a pacemaker

Acute pyelonephritis in pregnancy: a case series at Institute of Kidney Diseases and Research Centre

Acute pyelonephritis is one of the most common indications for antepartum hospitalization, estimated at approximately 9.7% of all indications for predelivery hospitalization, and when diagnosed, conventional treatment includes intravenous fluid and parenteral antibacterial administration, and careful monitoring of fluid balance. Here, we present four cases of acute pyelonephritis in pregnancy treated and patient successfully delivered with healthy babies

A successful pregnancy outcome after mitral valve replacement: a case report

Valvular heart disease can be acquired or congenital. Although the incidence of rheumatic heart disease is on the decline, the number of patients with congenital heart disease who survive into adulthood has grown substantially over the past 30 years. Therefore, a large number of patients with valvular heart disease will be of childbearing age. Here we presented a case of second gravida who was diagnosed with rheumatic heart disease and had undergone mitral valve prosthesis and tricuspid valve repair delivered a healthy live male baby weighing 2.250 kg
