    Copper and ZnS doped zinc sulphide thin films are equipped through chemicalbath deposition method (CBD). To find out the UV, XRD analyses are carry out.The linear nature of absorption indicates that ZnS (CU) is a direct band gapsubstance with the band gap energy equal to 0.3eV. The XRD image of the ZnS(CU) thin film gibes the in progression about the crystalline configuration preparedthin film. It confirms that the film has hexagonal crystalline structure

    Concept Map is a graphic device in which the concepts are linked by propositions leading to the precision and enhancement of meaning of the concept.” It is a schematic device for representing a set of concept meanings embedded in a hierarchy from most general concept to specific concepts of a learning unit. The study aimed to examine the concept mapping in teaching science among IX std students. The investigator adopted experimental method to study the concept mapping in teaching science among ix std students. For this study a sample of 60 IX std students from schools which are situated in Coimbatore district in Tamil Nadu. The findings reveal that is inferred that there is a difference in concept mapping in teaching science among ix std students

    Let Pk+1 denote a path of length k, Sm denote a star with m edges, and Kn(λ) denote the complete multigraph on n vertices in which every pair of distinct vertices is joined by λ edges. In this paper, we have obtained the necessary conditions for a {Pk+1, Sm}-decomposition of Kn(λ) and proved that the necessary conditions are also sufficient when k = 6 and m = 4.The second author is supported by the University of New Delhi under the grant no: F.

    ANTIMICROBIAL ACTIVITY OF A PROTEASE INHIBITOR ISOLATED FROM THE RHIZOME OF CURCUMA AMADA

    Get PDF
      Objective: Protease inhibitors (PIs) are effective antimicrobial agents, and this study was aimed to study the antibacterial efficacy of a PI isolated from the rhizome of Curcuma amada.Methods: A proteinaceous protease inhibitor was isolated from the rhizome of C. amada and purified by Sephadex G-50 gel permeation chromatography. The purified inhibitor was denoted as Curcuma amada protease inhibitor (CAPI). The antibacterial effect of CAPI against Gram-positive and Gram-negative bacteria, the minimal inhibitory concentration (MIC), and minimal bactericidal concentration (MBC) of CAPI was studied in vitro, and the membrane disruption activity of CAPI was also analyzed.Results: CAPI was effective against both Gram-positive and Gram-negative bacteria, with slightly higher concentrations required for Gram-negative bacteria. The MIC ranged from 75 to 100 μg/ml and the MBC ranged from 100 to 125 μg/ml of CAPI. The study of membrane disruption by CAPI revealed the release of cell contents, namely, reducing sugars and proteins from the bacterial cell.Conclusion: A PI was effectively isolated from the rhizome of C. amada, and the isolated inhibitor proved to be a promising antibacterial agent

    Despite the fact that there are many applications for analyzing and recreating the audio through existinglip movement recognition, the researchers have shown the interest in developing the automatic lip-readingsystems to achieve the increased performance. Modelling of the framework has been playing a major role inadvance yield of sequential framework. In recent years there have been lot of interest in Deep Neural Networks(DNN) and break through results in various domains including Image Classification, Speech Recognition andNatural Language Processing. To represents complex functions DNNs are used and also they play a vital rolein Automatic Lip Reading (ALR) systems. This paper mainly focuses on the traditional pixel, shape and mixedfeature extractions and their improved technologies for lip reading recognitions. It highlights the mostimportant techniques and progression from end-to-end deep learning architectures that were evolved duringthe past decade. The investigation points out the voice-visual databases that are used for analyzing and trainthe system with the most common words and the count of speakers and the size, length of the language andtime duration. On the flip side, ALR systems developed were compared with their old-style systems. Thestatistical analysis is performed to recognize the characters or numerals and words or sentences in English andcompared their performances

    A study of the socio demographic and obstetric factors in pregnant women with COVID-19 infection at a tertiary care hospital, Kollam, Kerala, India

    Background: The first wave of the COVID-19 pandemic took the world to task. Pregnant women needed care without actually knowing if the treatment schedules outside of pregnancy could be extrapolated to the pregnant state. Obstetric protocols were adhered to as far as was feasible, yet world over there was an increase in cesarean section rates. The so-called alpha variant that we saw at the time appeared to infect pregnant women too with equal frequency but they fared well. The issues regarding infectivity and the use of personal protective equipment (PPE) assumed mammoth dimensions. The objectives of this paper were to explore the demographic data and the epidemiological risk factors and study the symptomatology, severity and course of COVID-19 in pregnancy.Methods: This was an observational study conducted on all the COVID-19 positive pregnant women admitted to the department of obstetrics and gynecology at the designated COVID hospital for the district - Government Medical College Kollam - for a period of 6 months from October 2020 to March 2021. These women were studied with respect to their socio demographic details and their Obstetric risk factors and performance. Data was collected and analyzed using statistical package for the social sciences (SPSS) software.Results: 377 antenatal COVID-19 positive women were admitted and analyzed during the study period. Nulliparous women (48.5%%) in the age group 20 to 30 years (74.28%) formed the major group. Third trimester and near date admissions were the majority (48.80%). Most women (79.31%) were asymptomatic. Most common symptoms were fever in 35% and flu like upper respiratory symptoms (20%). Breathlessness and lung involvement was seen in 2.91%. Contact tracing revealed a travel history or contact with infected persons at 15.64%. However, 84.8% had no contact history. All antenatal women were tested at admission and reverse transcriptase-polymerase chain reaction (RTPCR) was done in 73.21%. Rapid antigen and nucleic acid amplification test (NAAT) detected the rest. 46% had some co morbidity gestational diabetes mellitus (GDM), gestational hypertension, thyroid disease and anemia were the common co morbidities detected. The presence of GDM in 24.14% of the study population is noteworthy.Conclusions: Pregnancy being an immune compromised state, unpredictable outcomes are possible with COVID-19 infection. Asymptomatic patients too can experience complications. Frequent hospital and lab visits could be a source of infection. The growing incidence of GDM in the midst of the COVID-19 pandemic is a point for concern
