Solar Cell Parameters Extraction from a Current- Voltage Characteristic Using Genetic Algorithm

The determination of solar cell parameters is very important for the evaluation of the cell performance as well as to extract maximum possible output power from the cell. In this paper, we propose a computational based binary-coded genetic algorithm (GA) to extract the parameters (I0, Iph and n) for a single diode model of solar cell from its current-voltage (I-V) characteristic. The algorithm was implemented using LabVIEW as a programming tool and validated by applying it to the I-V curve synthesized from the literature using reported values. The values of parameters obtained by GA are in good agreement with those of the reported values for silicon and plastic solar cells. change to “After the validation of the program, it was used to extract parameters for an experimental I-V characteristic of 4 × 4 cm2 polycrystalline silicon solar cell measured under 900 W/m. The I-V characteristic obtained using GA shows excellent match with the experimental one. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/3100

Use of Panicker’s cannula in management of atonic postpartum hemorrhage

Postpartum hemorrhage (PPH) is leading cause of maternal mortality worldwide. Panicker’s cannula creates negative pressure inside the uterus that causes shrinking of the uterus which can assist the physiological process of contraction and retraction to stop atonic postpartum hemorrhage. It is safe and simple technique to prevent and treat PPH. It can be used in low-resource and primary care settings, where even para medical personnel can use this method effectively to prevent morbidity and mortality. This can also be used in non-PPH conditions. In this study total 20 women with singleton pregnancy (14 had vaginal delivery and 6 underwent cesarean section), who developed atonic postpartum hemorrhage were included in the study. Panicker’s cannula was used in the patients, in whom bleeding was not stopped despite using uterotonics. Cessation of complete bleeding was observed in all 20 women within 4 minutes, which was associated with contraction and firm retraction of the uterus. Amount of the blood in bottle ranged from 150-250 ml. Vacuum retraction of uterus assists in the normal physiological process of contraction and retraction. This simple and cost effective technique, takes very little time to stop bleeding. This lifesaving technique is useful in all settings especially in low resource settings

A comparative study of ferric carboxymaltose and iron sucrose as a parenteral iron treatment in iron deficiency anaemia during pregnancy

Background: Iron deficiency anemia during pregnancy is a serious global concern specially in developing country, which is preventable with effective measures. In women who cannot tolerate oral iron or have moderate to severe anemia, parenteral iron in the form of iron sucrose or ferric carboxymaltose can be very much useful. This study aimed to compare efficacy and safety of iron sucrose and ferric carboxymaltose in iron deficiency anemia during pregnancy.Methods: This prospective interventional comparative study was conducted during May 2016 to April 2018 at tertiary care hospital and total 100 antenatal women from 28 to 34 weeks of gestation having moderate to severe anemia were included in this study and all women were divided in to 2 groups randomly and were given either iron sucrose or ferric carboxymaltose according to iron requirement. Rise in haemoglobin and serum ferritin were noted and data analysed statistically.Results: The mean rise of haemoglobin with iron sucrose was 1.8 gm% and with ferric carboxymaltose was 2.6 gm%. The mean rise of serum ferritin with iron sucrose was 82.4 ng/ml and with ferric carboxymaltose was 100.9 ng/ml. Other than minimal local reaction one woman had developed severe anaphylactic reaction after receiving iron sucrose.Conclusions: Intravenous ferric carboxymaltose is better and safe molecule than iron sucrose and it has advantage of ability to administer large dose in single sitting which reduce overall cost of therapy.  Hence ferric carboxymaltose is a drug of choice as parenteral iron therapy in iron deficiency anemia during second trimester of pregnancy.

Laparoscopic colorectal cancer surgery - a prospective study of short-term outcomes of consecutive cases over 3 years

This study was carried out with the objectives to study the feasibility of laparoscopic colorectal cancer resection, to observe short term outcome such as recovery parameters, oncologic safety, morbidity and mortality, and to analyze the experience of laparoscopic colorectal surgery in a teaching hospital. Between January 2007 and July 2009, all consecutive adult cases admitted to our department for colorectal cancer were assessed for eligibility. The ethical committee approved the protocol at the Sterling Hospital. Out of 31 patients,17 were males and 14 females. The mean age was 59 years. The most common clinical presentation was weight loss and altered bowel habits. Rectum (51.61%) was the most commonly involved organ followed by cecum (22.58%). - median time to liquid diet was two days (range 1-22), and a solid diet was three days (range 3-30). The median time to first flatus was two days (range 1-5), and the first stool was five days (range 3-7). The postoperative stay was eight days (range 6-30) median time to mobilization was 2.5 days. The postoperative stay is cumulative and includes patients who underwent reoperation for the anastomotic leak. The median operating time was 240 mins (range 116 – 520). The median length of incision was 6 cm (range 4 – 10 cm). The median blood loss was 170 ml. Blood loss was higher in patients with hemorrhage and tumor adhesions, and both of them were converted to open. These patients incidentally had a more extended hospital stay. The laparoscopic technique for colorectal cancer is feasible and safe. Laparoscopic colorectal surgery (LCS) is associated with short term benefits like the earlier return of gastrointestinal function and shorter length of hospital stay. From the oncologic point of view, tumor resections are adequate, taking into context numbers of lymph nodes retrieved and resectional margins in context to oncologic safety. The decreased postoperative wound infections and early recovery facilitate appropriate adjuvant therapy. Advanced laparoscopic surgery requires a team approach with proper case selection. Transvaginal delivery of specimens can give scar-less surgery and the option for assisted natural orifice surgery

Effects of Annealing on Structural Properties of Copper Zinc Tin Sulphide (CZTS) Material

Copper Zinc Tin Sulphide compound was synthesized from its elemetal precursurs using simple solid state method. Being quarternary material, there is a large probability of formation of secondary phases like SnS, ZnS, CuS during the material growth process and it requires a detail investigation on the effects of synthesis parameters on the composition and structural properties of the CZTS compound. Here we report the study of effects of annealing on the synthesized compound. The annealing was performed at two different temperatures in the presence of Sulphur. The structural and compositional properties of the as-grown and annealed samples were examined by X-ray diffraction (XRD) and Energy Dispersive Analysis of X-Ray (EDAX). The formation of Kesterite CZTS phase was confirmed by Raman Spectroscopy. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/3102

FORMULATION AND DEVELOPMENT OF CURCUMIN BASED EMULGEL IN TREATMENT AND RECURRENCE OF VAGINAL CANDIDIASIS

Objective: The main causative agent of vaginal candidiasis is Candida albicans and it develops resistance against several synthetic antifungal drugs and it has a high rate of infection in women. According to WHO report, around 75% of women are infected by Candida albicans and 50 % are infected a second time by Candida albicans. Therefore, we choose Curcumin an antifungal agent that had reported antifungal properties against the various fungal species. The Curcumin-containing emulgel based microemulsion system was prepared for greater retention time and penetration across the vaginal mucosa. Methods: The screening of oil phase, surfactant, and cosurfactant for microemulsion formulation was selected based on the solubility study and followed by the construction of the pseudoternary phase diagram. The oil phase, surfactant and co-surfactant are selected from the pseudoternary phase diagram for the formulation of a stable microemulsion. The prepared Curcumin-loaded microemulsion was characterized by globule size, polydispersity index, Zeta potential, accelerated stability study, drug content, percent transmittance and antifungal assay by broth microdilution technique. The formulated microemulsion was converted into a vaginal emulgel by using Pluronic@F127. The formulated curcumin-loaded emulgel was characterized by different evaluation parameters and antifungal study by agar well diffusion method. Results: The result showed that the average globule size of emulgel was 286.3 nm, polydispersity index was 0.241, Zeta potential was+19.20 mv, conductivity was 0.0390 mS/cm, and drug content was found to be 95.58%. The texture of formulated emulgel was found to be soft and smooth, with shear-thinning, pseudoplastic behavior, and easily spreadable. The in vitro permeability study of emulgel shows slow and complete release of curcumin in 10 h. The microemulsion and developed emulgel showed promising antifungal activity against Candida albicans. Conclusion: The developed curcumin-loaded emulgel showed promising antifungal activity against Candida albicans as compared to the Fluconazole as an standard antifungal antibiotic. Our formulated Curcumin-containing emulgel can be a potential alternative as compared to the conventional dosage form for the treatment of vaginal candidiasis
