DRUG pKa VALUE PREDICTION – FROM COMPRESSED GRAPH
Objective: Topological indices are interesting since they capture some of the properties of a molecule in a single number. pKa value indicates the strength of the acid in each molecule of the chemical compounds or drugs. The objective of this research was to predict the pKa value of drugs using graph theory.
Method: In this paper, we use a graph property eccentricity and the regression, a statistical model to predict the value of pKa by compressing the hexagonal system of the graph structure of drugs which reduces the calculation of eccentricity.
Results: pKa value of the new medicine can be determined using regression analysis by fitting in a linear equation of a straight line.
Conclusion: The results obtained in this research work clearly indicated that we found out the pKa value of local anesthesia which has similar structures. Further, we can use this method for other physicochemical properties such as boiling point, melting point, and vapor pressure by compressing the drug graph
Isolation, purification, characterization and applications of serine protease from Bacillus megaterium
Bacillus megaterium isolated from poultry farm soil was identified by standard biochemical tests and screened for the production of serine protease. Production of serine protease was done using 5 different medias by varying the type of amino acid added. The purification was done by salt precipitation, dialysis and DEAEcellulose ion exchange chromatography. The proline containing media obtained the highest fold purification out of the five different medias (leucine, lysine, proline, tryptophan and methionine cotaining media). The enzyme showedan optimal activity at the temperature 37°C and the pH 6 which are known as its optimum temperature and pH respectively. The enzyme was proved as a Mn2+ dependent serine protease as it was activated by Mn2+ ions and inhibited by PMSF. The molecular weight of the enzyme was determined by SDS-PAGE technique as around 30kDa. It showed an excellent detergent activity on the blood stains and a very good stability in presence of locally available detrgents. The enzyme acted on the keratin protein of the chicken feather and showed a degrading capacity on the protein. So it was proved that the recently studied serine protease has a keratinase activity also. From these datas I conclude that the protease isolated from Bacillus megaterium is a Mn2+ dependent serine protease which has both keratinase and detergent activity
Super-Resolution Overlay in Multi-Projector Displays
A technique, associated system and computer executable program code, for projecting a superimposed image onto a target display surface under observation of one or more cameras. A projective relationship between each projector being used and the target display surface is determined using a suitable calibration technique. A component image for each projector is then estimated using the information from the calibration, and represented in the frequency domain. Each component image is estimated by: Using the projective relationship, determine a set of sub-sampled, regionally shifted images, represented in the frequency domain; each component image is then composed of a respective set of the sub-sampled, regionally shifted images. In an optimization step, the difference between a sum of the component images and a frequency domain representation of a target image is minimized to produce a second, or subsequent, component image for each projector
An Optimization Model for Secure Sharing of Visual Cryptographic Images Generated by Using arbitrary Pixel Stereogram
Visual cryptography schemes (VCSs) are the methods to provide data security in network systems by generating random and non meaningful shares of a original image under consideration. There occurs a problem of transmission loss and also the possibility of the intruder attack when the shares are passed within the same network. Previous research have focused on hiding the shares in halftone images but the possible risks they lead to are pixel expansion problems and degradation in the quality of the resultant images. Hence a binocular VCS (BVCS) and an encryption algorithm are proposed to hide the shared pixels in the single image random dot stereogram’s (SIRDSs) along with the different modes of transmission for the generated possible shares. Since the SIRDSs have the same 2D appearance as the conventional shares of a VCS, this paper tries to use SIRDSs as cover images of the shares of VCSs to reduce the transmission risk of the shares. The encryption algorithm used may modify the random dots in SIRDS’s to equalize the quality of the resultant image. This process is done using the construction rule of BVCS. Altering the dots may also have a impact on the pixel quality and hence an optimization model based on the quality requirement is used. Finally the shares are passed to the recipients over varied networks

Maternal and perinatal outcome in abruption placenta in tertiary care center: a record based case series study
Background: Abruptio placenta is premature separation of the normally implanted placenta before delivery. It is one of the leading causes of maternal morbidity and neonatal morbidity and mortality, more so because of the difficulty to predict the acute event. It occurs in approximately one in 80 deliveries and remains a significant cause of perinatal mortality and morbidity. Objective of the study was to study maternal and perinatal outcome in cases of abruption.
Methods: 42 cases of pregnant women who presented with abruption placenta to HSK hospital and Research Centre, S. Nijalingappa Medical College, a tertiary care centre at Bagalkot, from January 2022 to December 2022. Maternal and perinatal characteristics were retrieved from the case papers.
Results: Among 42 cases of abruption 70% delivered vaginally and 30% underwent caesarean section. 84% had preterm delivery. 66% were still born. 21% were case of severe anaemia and required blood transfusion. 1 had maternal mortality.
Conclusions: The availability of advanced emergency obstetric care across greater number of referral hospitals has been responsible for decreasing the morbidity and mortality associated with many obstetric conditions. However, the challenge with abruptio placenta is the difficulty of predicting this condition, and hence appropriate management. As of now, early referral to tertiary care centres, better availability of blood and blood products and early interventions have the potential to limit adverse maternal and perinatal outcomes. Research regarding predictors of placental abruption can help in improving maternal and perinatal outcome.
