    Full text link
    In this article, by making use of the linear operator introduced and studied by Srivastava and Attiya \cite{srivastava1}, suitable classes of admissible functions are investigated and the dual properties of the third-order differential subordinations are presented. As a consequence, various sandwich-type theorems are established for a class of univalent analytic functions involving the celebrated Srivastava-Attiya transform. Relevant connections of the new results are pointed out.Comment: 16. arXiv admin note: substantial text overlap with arXiv:1809.0651

    Background: Surgical site infection following cesarean delivery leads to increasing the duration of patient hospitalization, hospital costs and raise the burden on our healthcare system. The incidence of SSI after cesarean range from 3% to 5%. Objective of current investigation was to study the risk factor & microbial agents responsible for SSI in LSCS and impact of SSI on perinatal outcome.Methods: This prospective study was done among 324 pregnant women undergoing LSCS at department of obstetrics and Gynecology in GMERS medical college & hospital, Sola, Ahmedabad during April 2015 to April 2016. All patients were following up to 7thpostoperative day.SSI was defined by CDC criteria.Results: The incidence of SSI noted in present study was 8.02%. Almost 46.2% cases had BMI ≥25 kg/m2, 65.4% multipara, 34.6% resided in rural area of SSI group. PIH, PROM, LSCS in emergency, multiple vaginal examination (>3), perioperative blood glucose (≥110 mg/dl), duration of surgery (≥60 min), past H/O of LSCS noted in participants of SSI was 30.8%, 30.8%, 96.1, 19.3%, 84.6%, 23.1%), 73.1% respectively. Staphylococcus aureus was the most common microorganism identified and incidence of NICU admission was 11.5% in SSI group.Conclusions: Incidence of SSI in present is 8.02%. BMI, PIH, PROM, LSCS in emergency, multiple vaginal examination (>3), perioperative blood glucose (≥110 mg/dl), duration of surgery (≥60 min), Past H/O of LSCS were noted statistically significantly higher among the participants of SSI group. Staphylococcus aureus was the most common organism identified

    Increasing industrialization and motorization led to a significant rise in demand of petroleum products. As these are the non-renewable resources, it will be troublesome to predict the availability of these resources in the future, resulting in uncertainty in its supply and price and is impacting growing economies like India importing 80% of the total demand of the petroleum products. Many attempts have been made by different researchers to find out alternate fuels for Internal Combustion engines. Many alternate fuels like Biodiesel, LPG (Liquefied Petroleum Gas), CNG (Compressed Natural Gas) and Alcohol are being used nowadays by different vehicles. In this context pyrolysis of scrap tires can be used effectively to produce oil, thereby solving the problem of waste tire disposal. In the present study, Experimental investigations were carried out to evaluate the performance and emission characteristics of a single cylinder diesel engine fueled by TPO10, TPO15, and TPO20 at a crank angle 260 before TDC (Top Dead Centre) and injection pressure of 190 bar keeping the blend quality by controlling the density and viscosity of tire pyrolysis oil within permissible limit of euro IV diesel requirement. The performance and emission results were analyzed and compared with that of diesel fuel operation. The results of investigations indicate that the brake thermal efficiency of the TPO - DF blend decreases by 2 to 3%. CO emissions are well within permissible limits. HC emissions are higher by about 20 to 40% at partial load whereas smoke opacity is lower by about 20 to 30% as compared to diesel fuel

    Background: Thrombocytopenia is second only to anemia as the most common hematological abnormality encountered in pregnancy. Better antenatal care has led to increased detection. Once diagnosed, it is Important to further evaluate and to determine the cause to optimize management. The objectives were to study feto-maternal outcome in patient of thrombocytopenia in terms of maternal and neonatal complications and to study the causes of thrombocytopenia in pregnancy. Methods: The present study was a hospital-based study carried out from June 2021 to June 2022 at the department of obstetrics and gynecology, PDU medical college, Rajkot, Gujarat. During this period 100 patients in the third trimester of pregnancy with thrombocytopenia were selected randomly. Results: In this study 41% cases were mild thrombocytopenia, 39% with moderate and 20% were severe cases. 50% cases were gestational thrombocytopenia, 31% were cases associated with hypertensive disorders of pregnancy, 8% cases were associated with abruption, 13% cases were associated with IUFD, 2% cases were idiopathic thrombocytopenic purpura (ITP), 8% cases were associated with viral (dengue) and bacterial (malaria) infection, 1% cases were associated with SLE, 1% cases was thrombotic thrombocytopenic purpura (TTP). Maternal complications were encountered in form of DIC in 13% cases, jaundice in 7% of cases, 2% cases were complicated by PPH, 4% cases were complicated by acute kidney injury, 2% cases were associated with sickle cell crisis and 4% cases were maternal mortality. 12% were stillbirth and 5% cases had neonatal mortality. Conclusions: Thrombocytopenia in pregnancy induced hypertension carries a risk for both the mother and her fetus. Thrombocytopenia in pregnancy if timely diagnosed do not cause any mortality, however management of these patients require a multidisciplinary approach and close collaboration between obstetrician, physician, and neonatologist

    Evaluation of whey protein concentrate as a functional ingredient on quality of goat milk rasogolla - an Indian dessert

    In the literature, a variety of dairy products are made from goat milk; however, information related to the manufacture of rasogolla from goat milk is very scant. During preliminary trials, it was observed that chhena prepared from goat milk was not suitable for the preparation of rasogolla because it has a very soft and sticky body that is difficult to handle. Therefore, this investigation was conducted to formulate an acceptable quality goat milk rasogolla using whey protein concentrate (WPC) as a functional ingredient. Chhena (also known as Indian cottage cheese, a heat- and acid-coagulated indigenous dairy product) was prepared from fresh Surati goat milk (3.5% fat/8.5% milk solids-not-fat (MSNF). Twelve batches of rasogolla were prepared from chhena coagulated at three temperatures viz. 75, 80 and 85⁰C containing WPC at 4 levels (i.e., 0, 0.25, 0.50 and 0.75% w/w of milk). Rasogolla prepared from chhena containing 0.50% WPC in milk  and coagulated at 80°C was preferred the most with respect to all the sensory attributes evaluated. It had significantly (P<0.05) highest sucrose content, i.e., 35.73% and a higher sugar absorption ratio, i.e., 2.63, compared to all the other experimental samples. The composition of drained samples of goat milk rasogolla was as follows: moisture 50.07%; protein 7.04%; fat 6.44%; ash 0.45% and sucrose 35.73%. The pH was 6.34 and acidity was 0.76% lactic acid. Based on the results obtained in this study, a method was developed for the preparation of acceptable quality goat milk chhena and rasogolla

    Introduction: Preparation of herbo-mineral compounds in Ayurveda revolves around mercury, considered as the prime among all minerals. Sulphur is again an important element used in many disorders and applied substance in different Ayurvedic formulations, considered as the antidote for the harmful mercurials. Kajjali is prepared by grinding mercury and sulphur. The prepared Kajjali used as a raw material for Rasasindura preparation with Kupipakva method. Kupipakva method is developed by ancient Rasaacharya for the preparation of heat treated mercurial. Dviguna gandhak jarita parada is considered more potent compare to Samaguna bali jarita. Objective: To study Kupipakva kalpana with preparation of Dviguna-bali jarita Rasa sindura. Methodology: Whole process is divided and performed as Sodhana of contents (Hingula and gandhaka), Hingulotth parada extraction, Kajjali preparation, preparation of Dviguna balijarita Rasa sindura. Observation: Hingula after Shodhana became soft and lusterless compound and Gandhaka becomes granular and brittle. Hinguloth parada extraction by Kanduka yantra method shown more yield compared to other methods. Kajjali preparation took 96 hours of Mardana of contents with Nischandra property. It took 48 hours for Dviguna Bali Jarita Rasasindura preparation by Kupipakva kalpana method with a yield of 106g. Conclusion: Preparation of Dviguna Balijarita Rasasindura needs more duration of heat treatment in every step of graded heating pattern of Kupipakva kalpana. The heating pattern is proportional to its therapeutic efficacy
