The present study was conducted during kharif (July-November, 2020) at the Department of plant pathology, N. M. College of Agriculture, Navsari Agricultural University, Navsari, Gujarat, India to isolate, purify and identify the pathogen responsible for rice bacterial blight. The pathogen was isolated from infected rice leaves and purified through streaking techniques, with its cultural and morphological characteristics utilized for identification. The analysis revealed that colonies grown on nutrient agar media exhibited traits consistent with Xanthomonas oryzae pv. oryzae, appearing raised, creamy yellow, smooth, entire and buttery as cultural characteristics and the bacterium as possessing a rod-shaped structure, gram-negative staining, encapsulation and non-spore formation as morphological characteristics. Furthermore, a pathogenicity test was conducted on the susceptible rice cultivar GR-11, cultivated in pots under controlled conditions within a net house was successfully satisfying Koch’s postulates. Rice (Oryza sativa L.) is one of the important cereal crop and a crucial dietary staple grown extensively in Gujarat, where it plays a significant role in ensuring food security and sustainability. However, rice bacterial blight remains a persistent threat, leading to substantial losses in both quantity and quality. To address this issue the investigation provided valuable insights into understanding the pathogen, thereby contributing to the development of cost-effective solutions for managing rice bacterial blight, which helps in increasing crop yield to the rice growing farmers of Gujarat.

Published: April 2024

Litter traits and site conditions alter nutrient inputs from deciduous and evergreen forests by influencing litter decomposition processes. Here, we investigated the leaf and stem mass loss rate (MLR) of a deciduous (Tectona philippinensis) and an evergreen (Parashorea malaanonan) tree species and the factors influencing it through an intersite experiment and litterbag method in secondary forests in Lobo, Batangas and Mount Makiling Forest Reserve (MMFR). Variations in initial litter quality (leaf area, specific leaf area (SLA), leaf thickness, vein density), and site factors (light intensity and temperature) were assessed. P. malaanonan has a lower SLA and vein density than T. philippinensis. The leaf and stem MLR were significantly higher in the mixed litter (44.09–57.83%) than that of a single-species litter of either T. philippinensis (28.16–41.83%) or P. malaanonan (33.60–47.66%). The leaf MLR of T. philippinensis was greater when placed in Lobo (where the litter originated) than at a different site (i.e., MMFR). Moreover, leaf litter decomposition was faster in T. philippinensis than in P. malaanonan, particularly during the rainy season. Overall, the study showed that litter decomposition in deciduous and evergreen differed across sites due to variations in litter quality and environmental variables.

Published: April 2024

Recognizing pneumonia sufferers can be done by analyzing chest X-ray images. Pneumonia sufferers experience pleural effusion, where fluid is between the lungs’ layers. It causes the lungs’ X-ray picture to be cloudy or hazy. It differs from the appearance of X-rays on normal lungs which are dark in color. These differences in X-Ray images can be classified automatically with the help of Artificial Intelligence This research used convolutional neural networks and support vector machine methods to recognize X-ray images of pneumonia. This research applied Principal Component Analysis and Wavelet Transformation support to both methods. This research aimed to evaluate the performance of each model combination. The PCA-SVM model gave the best performance, with an accuracy of 94.545% and an F1 score of 94.675%. The SVM model outperforms the CNN model in recognizing images; in this case, it could be due to the relatively small amount of training data.

Published: April 2024

Communication is a habitual thing for every human, whetherit's communicating directly orindirectly. When a natural
disaster happens, problems can occur on communication systems. These problems can lead to information being not
received properly, so the two parties communicating didn’t know the content of the message. In this situation,
a two-way radio device is the best solution that can be used to communicate. A two-way radio device enables the user
to communicate without any cellular network or internet, because the radio can be both a transceiver or a receiver
in its own frequency. A common two-way radio device uses UHF frequency range (400 MHz - 520 MHz) because
of the characteristics of this frequency range that can penetrate buildings or vegetation that usually interfere with the
radio signal. However, a two-way radio device has a broadcast and unencrypted characteristic, so that every
conversation that is happening between the radio users can be heard by other users. In an emergency situation such
as a natural disaster, important and confidential information shouldn’t be heard by an unauthorized person. So in
this project, the writers have a goal to design an encrypted text based communication system that works on the UHF
frequency band.

Abstract. We investigate the impact of the percentage of clean water access, the percentage of handwashing habit, and the toilet category factors on the upper quantile of toddlers’ diarrhea risks in Bandung city, Indonesia using Geographically Weighted Quantile Regression model. We analyzed districts in Bandung, applying Geographically Weighted Quantile Regression with the predictors are the percentage of clean water access, hand washing habit, and toilet category. We focus on the 75th percentile ( . Breusch-Pagan test was used to detect the spatial heterogeneity. The optimum bandwidth was selected using cross-validation. The results shows that the significance, strength, and direction of the relationship between diarrhea and its risk factors are found to depend on the location. At the upper quantile τ = 0.75, the district named Panyileukan district is predicted to have the highest diarrhea risk. In this district, all of the three predictors are significantly affecting the toddlers’ diarrhea risk with the variable of percentage of houses practicing hand washing habit is observed to reduce diarrhea risk the most. In conclusion, clean water access, handwashing habits, and toilet category are the potential risk factors of high-risk childhood diarrhea. The significance, strength, and direction of the effect varies between districts. This method is powerful as it would allow the decision maker to handle the diarrhea problem aptly based

Published: April 2024

The modern arsenal of drugs aimed at eliminating pathological processes of the anorectal zone, as a rule, consists of suppositories and soft drugs. When using suppositories, hemorrhoidal nodes may be injured, uneven distribution of the drug along the walls of the anal canal may be observed. In addition, with external and combined hemorrhoids, there is a need to apply the drug not only to the walls of the anal canal, but also to the perianal skin. Therefore, preference is given to the use of soft drugs since the process of their introduction is as easy as possible. Today, the pharmaceutical market of Ukraine has a wide range of products for the treatment of diseases of the anorectal zone, but the constant increase in the number of patients indicates that this problem has not been solved. Therefore, the study on the creation of a new rectal soft medicine that will have a complex effect on pathological processes and expand the range of domestic drugs for use in proctology is relevant.
Aim. To substantiate the type of base for a soft rectal medicine by studying the organoleptic and physicochemical properties of the experimental samples.
Materials and methods. The study objects were samples of a soft dosage form of various compositions and the reference drug “Procto-Glivenol Cream” (VAMPHARMA S.R.L., Italy). Samples on different carrier bases were examined by their organoleptic and textural properties; their colloidal and thermal stability, viscosity and pH were studied.
Results and discussion. It has been found that the use of a sample on a gel base with Aristoflex does not ensure the presence of an optimal adhesive layer between the mucous membrane of the anorectal zone and the dispersion medium of the drug. The proxanol-188 sample does not have satisfactory thermal and colloidal stability indicators. The use of an emulsion base provides the necessary ability to spread over the surface, adhesion and cohesion.
Conclusions. Therefore, for further research, it is advisable to use a sample of the rectal cream, which is an emulsion system.
