Entropy and Its Application to Number Theory
Authors: Fujino Seiji
Published: November 2023

In this paper, we propose an expansion of the Planck distribution function derived from the Boltzmann principle. Namely, we consider expanding Planck's law with a new distribution function, and discuss fine structure constant. Furthermore, using ideas applied to the expansion of the Planck distribution function, we show that Von Koch's inequality can be derived without using the Riemann Hypothesis, that is, the Riemann Hypothesis is true, and that the abc conjecture is negated. Furthermore, we define a generalization of Entropy and discuss that Entropy is relevant to dynamical systems described by logistic function models, such as the growth of bacteria or populations.

Authors: Um Kyung-Hwan , Shin Jong-Suh , Son Gi-Hwal , Park Byung-Ki
Published: November 2023

This study aimed to investigate the effects of lupin flake supplementation on the growth, plasma parameters, carcass characteristics, and meat composition of late-fattening Hanwoo steers. The steers (n = 40) were randomly divided into the four groups with 10 steers each: LP0 (Lupin flake 0%), LP3 (lupin flake 3%), LP6 (Lupin flake 6%), and LP9 (lupin flake 9%). The total digestible nutriant intake increased as the concentration of lupin increased (linear and quadratic effects; P < 0.05). The thiobarbituric acid-reactive substance content in the strip loins decreased as lupin flake supplementation levels increased (linear and quadratic effects; P < 0.05), while carnosine levels increased linearly (P < 0.05). As the lupin flake supplementation level increased, anserine and creatinine contents increased linearly and quadratically (P < 0.05). Similarly, adenosine triphosphate (ATP) and adenosine monophosphate (AMP) contents increased with increasing lupin flake supplementation levels in linear and quadratic effects (P < 0.001). Palmitoleic acid content increased significantly with increasing lupin flake supplementation level (linear and quadratic effects; P < 0.05). The content of oleic acid in the strip loin was not significant, but the unsaturated fatty acid (UFA) (P < 0.05) and n-6/n-3 ratio (P < 0.05) increased. The results of this study indicated that although lupin flake supplementation did not markedly affect the growth, carcass characteristics, or meat composition of late-fattening Hanwoo steers, it exerted a positive effect on the flavor, taste profiles (anserine, creatinine, ATP, and AMP), hypotonicity(TBARS), and healthy meat production (UFA and n-6/n-3 ratio) related to beef.
Concentration Prediction‐Based Crop Digital Twin Using Nutrient Co‐Existence and Composition in Regression Algorithms
Authors: Ghazvini Anahita , Sharef Nurfadhlina Mohd
Published: November 2023

Crop digital twin is redefining traditional farming practices, offering unprecedented opportunities for real-time monitoring, predictive and simulation analysis, and optimization. This research embarks on an exploration of the synergy between precision agriculture, crop modeling, and regression algorithms to create a digital twin for augmenting farmers the concentration and composition prediction-based crop nutrient recovery. This captures the holistic representation of crop characteristics, considering the intricate relationships between environmental factors, nutrient concentrations, and crop compositions. However, the complexity arising from diverse soil and environmental conditions makes nutrient content analysis expensive and time-consuming. This paper presents the result of a predictive digital twin case study that employs six regression algorithms namely Elastic Net, Polynomial, Stepwise, Ridge, Lasso, and Linear Regression to predict rice nutrient content efficiently, particularly considering the coexistence and composition of multiple nutrients. Our research findings highlight the superiority of the Polynomial Regression model in predicting nutrient content, with a specific focus on accurate nitrogen percentage prediction. This insight can be used for nutrient recovery intervention by knowing the precise amount of nutrient to be added into the crop medium. The adoption of the Polynomial Regression model offers a valuable tool for nutrient management practices in the crop digital twin, potentially resulting in higher-quality rice production and a reduced environmental impact. The proposed method can be replicable in other low-resourced crop digital twin system.

Published: November 2023

The aim of this literature review was to present the novel imaging modalities elastography and contrast-enhanced ultrasonography. We provided an overview of the concepts and applications of each technique for the investigation of neoplastic and metastatic tumors in dogs and cats. Studies with elastography are based on the elasticity and deformation of the evaluated tissue. The information obtained from the different types of elastography can aid in the detection and differentiation of malignant and benign structures. Descriptions of elastographic studies in several organs and tissue in veterinary medicine reported that, in general, malignant tumors tend to be more rigid, and, therefore, less deformable than benign lesions or in comparison to the healthy parenchyma. Contrast-enhanced ultrasonography is based on the intravenous injection of contrast media constituted by microbubbles. This imaging modality can be performed in non-sedated animals and provides information on the tissue perfusion, allowing the investigation of macro- and micro-circulation. Studies with different organs and tissues were performed in dogs and cats and revealed a tendency of malignant tumors to present faster transit of the contrast media (time to wash-in, peak and wash-out). These advanced techniques can be associated with other imaging modalities, aiding important information to the well-established exams of B-mode and Doppler ultrasonography. They can be used as screening tests, potentially representing an alternative to the invasive sampling methods required for cytological and histopathological analysis.
Unearthing Novel Insights: Hypericin's Interaction with Heat Shock Proteins
Authors: FERRARI IVAN VITO
Published: November 2023

Heat Shock Proteins play a crucial role in maintaining cellular integrity during thermal stress conditions, acting as chaperones and participating in the regulation of cellular responses. The focus was to contribute valuable insights into the potential role of hypericin in modulating these heat shock proteins and its implications for anti-tumoral properties. This study employs computational methods, specifically molecular docking, to investigate the potential biological interactions between the chaperone proteins HSP90 and HSC70 and Hypericin, a natural compound recognized for its anti-tumor properties. Despite the limited existing studies in this domain, this research aims to uncover structural insights into the binding mechanisms between Hypericin and these heat shock proteins. In the docking assessments, hypericin demonstrated notable binding energy results, exhibiting a binding energy of -10.5 kcal/mol with Heat Shock Cognate 71 kDa protein and -11.2 kcal/mol with Heat Shock Protein HSP90-alpha.
Influence of Perturbation’s Type and Location on Treadmill Gait Regularity
Authors: Błażkiewicz Michalina , Hadamus Anna
Published: November 2023

Background: This study aimed to investigate how external perturbations caused by the treadmill belt's acceleration (Acc) and deceleration (Dec) during the Initial Contact (Initial), Mid Stance (Mid) and Pre-Swing (ToeOff) phase affect gait regularity in young adults. Methods: Twenty-one healthy young females walked on a treadmill in a virtual environment (Grail, Motek), where four unexpected perturbations were applied to the left belt at Initial, Mid, and ToeOff. Sample Entropy (SampEn) was calculated for the center of mass (CoM) displacements, for six perturbation scenarios in three directions: anterior-posterior (AP), medial-lateral (ML), and vertical (vert), with SampEn vector lengths (m) ranging from 2 to 10. Results: The CoM displacement exhibited its highest regularity (low SampEn values) in the AP and vert-directions during Dec_ToeOff, across all m values. Similarly, this pattern was observed in the ML-direction, but exclusively for m = 2 and 4. The least regular CoM trajectories (high SampEn values) were for Dec_Mid in the AP-direction, across all m values. This trend persisted in the ML-direction, only for m = 2 and 4. However, the most irregular CoM displacements in the ML-direction occurred during Dec_ToeOff for the remaining m values. Vertical CoM displacements exhibited the highest irregularities during Dec_Initial for m ≥ 4. Conclusions: Evaluating the regularity of CoM displacements using SampEn can be a useful tool for assessing how gait perturbations are handled.

Published: November 2023

Chicken collagen is a promising raw material source to produce gelatins and hydrolysates. Gelatins and hydrolysates can be prepared biotechnologically using proteolytic enzymes produced by submerged fermentation of genetically modified microorganisms. By choosing the appropriate process conditions, such changes can be achieved at the molecular level of collagen, making it possible to prepare products with targeted properties for advanced cosmetic, pharmaceutical, medical or food applications. The research aims to investigate: i) antioxidant activity (DPPH and ABTS) in model samples of chicken collagen products (gelatin and hydrolysates); ii) distribution of molecular weights by the GPC-RID analysis method; iii) functional groups and configuration of polypeptide chains related to molecular level properties using FTIR; iv) the microbiological properties on SDA, PCA, TSA and VRBL microbial populations using MALDI method. Antioxidant activity towards ABTS radicals of more than 80% was found for all samples. The molecular weights of all gelatin samples showed typical α- and β-chains. FTIR analysis confirmed that the samples showed all typical vibrational regions for collagen cleavage products, Amide A and B, Amide I, II, and III at characteristic values. Microbiological analysis of the prepared samples showed no undesirable bacteria that would limit advanced applications of the prepared products. Gelatins and hydrolysates from chicken stomachs represent a promising alternative to products made from standard collagen tissues of terrestrial animals.

Published: November 2023

The effects of four cycles of recurrent selection on simple sequence repeat (SSR) marker allele frequencies and population structure were examined in the Maksimir 3 Synthetic (M3S) maize population (Zea mays L.). Genotyping of 32 plants from each cycle of selection at 38 SSR loci revealed that the mean number of alleles per locus and the mean expected heterozygosity were preserved over cycles of selection, indicating maintenance of sufficient genetic variability in the population needed for future genetic gain. Waples test of selective neutrality revealed that genetic drift was the main force in changing allele frequencies in the population. The proportion of selectively nonneutral loci in single cycles of selection varied between 16% and 37%. Some nonneutral loci shared the same genomic locations with previously published QTLs controlling important agronomic traits. Between 5% and 29% of loci were found to be in significant Hardy-Weinberg (HW) disequilibrium with the majority showing an excess of homozygosity. Excess of homozygosity at several loci was highly consistent across cycle populations suggesting positive assortative mating as the possible cause of the observed HW disequilibrium. Linkage disequilibrium (LD) tests revealed that the M3S population was essentially in linkage equilibrium. The proportion of pairs of loci in significant LD varied across cycles of selection between 0.1% and 1.8% probably due to the effects of genetic drift and epistatic selection.

Published: November 2023

Grapevine trunk diseases (GTDs) attack the vine's wood, devastating vineyards worldwide. Chile is the world's fourth largest wine exporter, and Cabernet Sauvignon leads the red wine varieties. Botryosphaeria dieback is an important GTDs and Diplodia seriata is one of the main pathogenic species. Biocontrol studies of these pathogens are commonly carried out at different incubation times but at a single temperature. This study aimed to evaluate the biocontrol effect of native Chilean bacteria against D. seriata isolates at different temperatures. We analyzed the biocontrol effects of Pseudomonas sp. GcR15a, Pseudomonas sp. AMCR2b and Rhodococcus sp. PU4, with three D. seriata isolates (PUCV 2120, PUCV 2142 and PUCV 2183) at 8, 22 and 35°C. Agar plug diffusion and double plate methods were used to evaluate the effect of diffusible and volatile organic compounds (DOC and VOC), and an in vivo test was performed with Cabernet Sauvignon cuttings. Pseudomonas strains showed the most significant inhibition in the DOC assay, and a demelanizing activity was observed. Rhodococcus sp. PU4 showed VOC biocontrol potential at high temperatures (35°C). In vivo, a biocontrol effect was observed against two D. seriata isolates, while the PUCV 2142 isolate proved to be more resistant to being controlled. The biocontrol ability at low temperatures is promising for effective control in the field, where infections occur primarily in winter.
The Effect of the Temperature on the Surface Energetic Properties of Carbon Fibers by Inverse Gas Chromatography
Authors: Hamieh Tayssir
Published: November 2023

This paper constitutes an original and new methodology for the determination of the surface properties of carbon fibers in the two oxidized and untreated forms by inverse gas chromatography technique at infinite dilution based on the effect of the temperature on the surface area of the various organic molecules adsorbed on the carbon fibers. The studied thermal effect proved a large deviation of the classical methods or models relative to the new determination of the surface properties of carbon fibers, such as the dispersive component of their surface energy, the free surface energy, the free specific energy, the enthalpy and entropy of adsorption of molecules on the carbon fibers. The obtained specific enthalpy and entropy of adsorption for the polar solvents led to the determination of the Lewis’s acid-base constants of carbon fibers. Different molecular models and chromatographic methods were used to quantify the surface thermodynamic properties of carbon fibers and compared to the thermal model. The obtained results proved that the oxidized carbon fibers gave more specific interaction energy and greater acid-base constants than that of the untreated carbon fibers and thus highlighting the important role of the oxidization on the acid-base of fibers. The determination of the specific acid-base surface energy of the two carbon fibers showed greater values of the oxidized carbon fibers relative to the untreated carbon fibers. An important basic character was highlighted for the two studied carbon fibers, larger than the acidic character. It was observed that the Lewis’s acid-base constants of the oxidized carbon fibers are larger than that of the untreated fibers with more accentuated basic charterer. This result was confirmed by all molecular models and chromatographic methods.

Published: November 2023

The CMT (Cold Metal Transfer) arc welding process is a convenient instrument for the assembly of thin sheets [1], [2]. More particularly, it permits the decrease of the amount of heat transferred to the parts to-be assembled, thus reducing their subsequent deformations.
The present work aims at simulating the CMT welding of thin stainless-steel sheets in order to develop an approach that allows the prediction of temperature fields, as well as final deformations induced by the welding process. For that purpose, instrumented tests and numerical simulations were set aiming at comparing the experiments with simulations.
Butt-welding of stainless-steel sheets was considered, with a thickness ranging from 1 to 1.2 mm. The weld seam samples were observed in order to set an equivalent heat source for each configuration. Moreover, the electric current and voltage were surveyed, and temperature measurements were performed using K-type thermocouples. In addition, displacement measurements were obtained using the DIC (Digital Image Correlation) technique.
Thermomechanical simulations were then carried out using an equivalent heat source approach, considering the phase changes of elements, i.e. the transitions from solid to liquid and from liquid to solid. These simulations also consider the actual geometry of seams induced by addition of a filler material.

WAYS OF ENSURING THE COMPETITIVENESS OF SMALL AND MEDIUM-SIZED MACHINE-BUILDING ENTERPRISES OF UKRAINE IN THE EUROPEAN INTEGRATION CONTEXT
Authors: Dobrotvorskiy Sergey , Basova Yevheniia
Published: November 2023

The issues of the modern direction of sustainable development of the competitive machine-building industry in Europe and the possibility of transforming the experience of developed European countries into a strategy for the development of small and medium-sized machine-building enterprises in Ukraine are considered. It was noted that it is SMEs that are the basis for the development of the EU economy, and the rationale for this fact was given. It was emphasized that the engineering industry is the largest sector of the EU economy in terms of the number of enterprises, employment of workers, production and value added. It is assumed that it is the development of SMEs in the machine-building industry of Ukraine that will become a significant contribution to the accelerated restoration of the social and economic well-being of Ukrainian society during the period of the country's recovery. A comparative analysis of the numerical number of machine-building enterprises of various sizes is given both in the developed countries of Europe and in Ukraine. The need for the development and implementation of digital services in the machine-building industry of Ukraine, in accordance with the concept of Industry 4.0, was emphasized at all stages of the product life cycle to ensure the flexibility and competitiveness of SMEs. The barriers to the implementation of the 4.0 concept for the sustainable development of small and medium-sized businesses in the world are analyzed, and individual barriers are identified that today pose a threat to the development of the Ministry of Railways of Ukraine as a whole. It is noted that one of the biggest problems in the world development of the Ministry of Railways as a whole is the problem of training (retraining) a new generation of qualified personnel. It is concluded that in order to develop competitive SMEs in Ukraine in the context of its integration into the EU, it is necessary to pay attention to the training of highly qualified technical personnel who, on the one hand, can play the role of system integrators and implementers of Industry 4.0 tasks, and, on the other hand, be able to solve the associated problems of mechanical engineering technology from idea to product manufacturing using digital services based on a single digital core. The scientific value of the work lies in the substantiation of ways to ensure the competitiveness of SMEs based on the foundations of the symbiosis of education, science and manufacture on the basis of a single digital core.
THEORETICAL AND EXPERIMENTAL JUSTIFICATION OF EFFECTIVE TECHNOLOGIES OF HIGH-SPEED MECHANICAL PROCESSING
Authors: Nоvikоv Fеdir Vаsilivyth , Polyansky Vladimir Ivanovich
Published: November 2023

A refined mathematical model for determining the conditional cutting stress during blade processing has been developed based on the establishment of an analytical dependence for determining the conditional shear angle of the processed material. It is shown that its formation is dominated by the radial component of the cutting force, which leads to its significant decrease (by 1.5 times) compared to the calculated values obtained according to known similar relationships. This made it possible to clarify the calculation of the parameters of mechanical processing power and thermal stresses and substantiate the conditions for their reduction by reducing the intensity of friction in the cutting zone. On the basis of the conducted experimental studies of the technological operations of mechanical processing of complex-profile forming equipment for the food industry, it was established that in the conditions of blade processing, the energy intensity and the maximum cutting temperature take much lower values than during grinding. Therefore, the possibilities of increasing productivity under the conditions of ensuring high quality processing during grinding are very limited. For this, it is necessary to apply modern technologies of high-speed blade processing on high-speed CNC metal cutting machines of the "machining center" type, which, as established in the robot, are characterized by extremely high technological capabilities.
MATHEMATICAL MODEL OF THE ELECTRO-HYDRAULIC CONVERTER OF THE HYDRAULIC TURBINE SPEED CONTROL SYSTEM
Authors: Hasiuk Oleksandr
Published: November 2023

Presents a mathematical model of an electro-hydraulic converter with proportional control. In the world and domestic practice of creating hydraulic turbine equipment, there is a clear tendency to create computer-based rotor speed control systems for hydraulic turbines. Computer systems provide an opportunity to implement the introduction of effective algorithms using software that improve the static and dynamic characteristics of the system. This in turn increases the importance of mathematical modeling both at the design stage and during commissioning. The analysis of the performed works devoted to the mathematical description of the elements of the hydraulic drive of the regulator showed that they are reduced to linearized equations without taking into account a number of important factors that will increase the accuracy of the mathematical model. Improvement of static and dynamic characteristics and the system as a whole can be achieved by solving the scientific problem of studying its dynamics based on the development of a more complete mathematical model. To reduce friction and hysteresis, to prevent obliteration, the electrohydraulic converter plunger in the lower part is equipped with a segner wheel. Improving the dynamic characteristics of hydraulic turbine speed controllers requires the development of nonlinear mathematical models with subsequent analysis of transients in the hydraulic drive of the speed controller. Evaluation of the quality of transient processes and subsequent adjustment of parameters allows to achieve a reduction in the duration of transients, increase the speed and accuracy of positioning at small movements of the servo motor. A number of unaccounted factors during the preparation of the mathematical model of the electro-hydraulic converter makes it possible to increase its adequacy to the real object of study and increase the speed of the control system of the rotor speed of the hydraulic turbine.

Authors: Cherpakov Mykyta
Published: November 2023

An overview of the use of computer vision systems, the complexity and problems of their development and use in modern industries that require automation of labor, and the introduction of the latest technologies to control the technological process. The main promising areas for the implementation of computer vision systems are highlighted. The main reasons for the complexity of building such systems, which have both the physical nature and the complex nature of computer vision as a discipline, are identified. The interaction of such systems with programmable controllers is considered. The use of programming languages for both controller programming and computer vision development is examined. These are C++ and Python programming languages for software development that have corresponding libraries that implement recognition and learning of systems by implementing machine learning, as well as ST, IL, LD, FBD, and SFC languages for controlling programmable controllers. Likewise, the implementation of basic requirements for computer vision systems, such as flexibility and scalability, is possible owing to C++ and Python languages with corresponding third-party libraries. The programming language in this case becomes a convenient tool for actualizing pre-implemented complex functions. Attention is drawn to the fact that automatic systems using computer vision are discrete-analog and require appropriate technical devices and programmable controllers. The technical elements that they should consist of are also considered.

Published: November 2023

The analysis of the complex interaction "fluid – structure" (Fluid Structure Interaction, FSI) is an actual scientific problem for many industries, such as hydroturbobuilding, shipbuilding, construction, etc., the solution of which is devoted to a significant amount of theoretical research. The paper analyzes works on the problems of approaches, models, research methods and the most famous FSI modeling software systems. Despite significant existing theoretical developments, the analysis of deformation of highly loaded structures, including hydroturbines and pumps, requires the development and adaptation of appropriate models and software systems. As a result of a series of studies, a mathematical model of the stress-strain state was developed and numerical modeling of blade hydraulic machines was performed. To reproduce the movement of elements of structures and fluids, the relations of the mechanics of continuous media are used. During calculations, it is possible to determine the fields of movements, stresses and deformations; natural frequencies of oscillations of elements of hydroturbines and pumps, as well as their sensitivity to changes in structural parameters. At the same time, a set of measures is provided for the creation and improvement of blade hydraulic machines with increased technical characteristics, as well as such design and operational parameters are determined that satisfy the conditions for increased strength. The developed technique makes it possible to purposefully carry out reconstruction from resonances at the design stage of blade hydraulic machines of various structural forms and to evaluate the impact of manufacturing and operational errors. Reduction of vibration of pumps, building structures and pipelines by 5–10 times at the Kharkiv bioremediation station, which is equipped with centrifugal pumps of the FDV-9000/45 type, n = 500 min–1 , was achieved by installing additional supports on pressure pipelines after vibration tests and calculation of pipelines for resonance, recommendations for further operation of the station are also provided.
Hikayat Raja Pasai Sebagai Sumber Historiografi Menurut Perspektif Syed M. Naquib Al-Attas
Authors: Wilandra Syaidina Sapta
Published: November 2023

Hikayat Raja Pasai dianggap sebagai salah satu naskah tertua yang menceritakan mengenai proses Islamisasi di kawasan Melayu-Indonesia. Sebagaimana historiografi tradisional lainnya, hikayat ini oleh para sarjana Barat seringkali dianggap sebagai cerita yang penuh mitos dan sangat subyektif sehingga kredibiltasnya dinilai berkurang, bahkan dianggap sebagai cerita fantasi semata. Anggapan ini ditolak oleh Syed M. Naquib Al-Attas, menurutnya hasil interpretasi para sarjana Barat itu karena adanya bias pandangan hidup mereka sehingga membangun metodologi penelitian sejarah yang sekular. Akibatnya mereka menganggap hasil karya sejarah tradisional seperti Hikayat Raja Pasai hanya sebatas sebuah karya sastra. Karena itulah Al-Attas kemudian mencoba melakukan pembacaan ulang terhadap Hikayat Raja Pasai yang merupakan karya historiografi tertua yang menjelaskan proses Islamisasi di Kepulauan Melayu-Indonesia. Di antara hasil intepretasinya terhadap hikayat ini adalah bahwa nama Samudra berasal dari kata semutraya, proses Islamisasi yang disebut dalam hikayat telah berlangsung sejak abad ke-9 atau 10 M dan dibawa oleh orang Arab Quraisy dari Mengiri, Merah Silu adalah tokoh fiksi, dan Malik as-Saleh bukanlah raja Muslim pertama dari Samudra Pasai.
Antara Salafi dan Sufi: Tasawuf menurut Ibn Taimiyyah dan al-Qusyairi

This article discusses two sects that are often contrasted: Salafi and Sūfī. It focuses on the views of Ibn Taimiyyah al-Ḥarrānī as a representative of Salafi and ‘Abd Karīm al-Qusyairī of Sūfī-sunnī on Sufism. By analyzing the works of Ibn Taimiyyah and al-Qusyairī on tasawuf, this article describes their views and then compares them. Ibn Taimiyyah wrote no less than thirty-eight treatises on Sufism and cited more than forty Sūfī texts in explaining and analyzing his views on Sufism. Al-Qusyairī, on the other hand, describes in detail the Sūfī figures and their views in his Risālah. He also included his Sufistic analyses in Laṭāif al-Ishārāt. Using an interpretative approach and content analysis, this article finds that Ibn Taimiyyah did not reject Sufism. He rejected the practice of Sufism that he thought was not intertwined with the Qur’ān and Sunnah. This is evident from his respect for al-Qusyairī, whom he called al-Syaikh al-Ustāż, and Mutaṣawwifah Ahl al-Kalām, a term of honor within the Ṣūfī order. Nonetheless, Ibn Taymiyyah notes that al-Qusayrī’s quotations in his work are not followed by references and explanations. In explaining the practice of zuhd, al-Qusyairī did not provide examples from the ṣaḥābah and tābi'īn to strengthen his argument.

The present study aimed to evaluate the physicochemical and microbiological quality and safety of pasteurized milk produced and sold in Bishoftu, Ethiopia. A total of 48 pasteurized milk samples were collected three brands of pasteurized milk. The overall mean of pasteurized milk were fat (3.08 ± 0.09%), protein (2.94 ± 0.06%), solid not fat (6.83 ± 0.17%), specific gravity (1.026 ± 0.00kg/l), add water (15.91 ± 1.85%), titratable acidity (0.16 ± 00%) and pH (6.64 ± 0.02). The overall mean of pasteurized milk were (log10 cfu/ml) aerobic mesophilic bacteria count (4.47 ± 0.10), total coliform count (2.05 ± 0.18), spore forming bacteria count (2.09 ± 0.10), yeast and mold count (2.00 ± 0.16) and E. coli (0.61 ± 0.06). The mean aerobic mesophilic bacteria count of pasteurized milk collected from Prime during non-fasting season (log10 cfu/ml 3.59 ± 0.23) was significantly lower than Mama and Holland dairy brands. The prevalence of salmonella in pasteurized milk the present study was nill. From this study it is possible to conclude that the physicochemical and microbiological quality and safety of raw milk collected B brand of pasteurized milk was substandard. Therefore, implementing strict milk quality control system and mandatory dairy product specification standard should be in place.

Multiple record-breaking rainfall events were observed along the Western Ghats (WG) during the recent monsoon seasons from 2019-2021. Rainfall amounts of up to >200 mm/day (Extreme rainfall, ER) were recorded especially over the Mumbai region (19.07N, 72.8E) causing flooding, landslides, damage to infrastructure and loss of life. Thus, to enhance the resilience of this region by providing early warning for flooding, the National Center for Medium-Range Weather Forecasting Unified model’s regional forecasting system (NCUM-reg) provides rainfall forecasts up to days (72-hour), which are utilized in the iFLOWS hydrological model. This study focuses on evaluating the performance of NCUM-reg forecasts during ER events. For this purpose, we have systematically performed model verification/assessment for 24 and 72-hour operational forecasts using the suite of observations (rain gauge, satellite) and newly generated NCMRWF’s regional reanalysis IMDAA. Key findings indicate the performance of a 4km regional model with explicit convection performing reasonably well in representing the key synoptic and dynamic features of the ER events. Quantitative assessment of the model forecasts shows the strength of in-situ observations. Taken together, results summarize the limitations of observations and stress the need for collective efforts of observations and systematic processbased verification methods to enhance the model's ability to forecast such extreme events.

The shading of soybeans in the traditional intercropping mode is an essential factor affecting the lignin content and stem-bending resistance of soybeans. A reasonable strip of intercropping crops is becoming more crucial as mechanization levels improve. In this study, we aimed to investigate the effects of different row ratios and planting patterns on canopy photosynthesis, stem bending resistance, cellulose, hemicellulose, lignin, and related enzyme activities of soybean in a maize-soybean intercropping system that uses two patterns and four intercropping ratios. Compared with the uniform-ridge planting pattern of soybeans, the narrow-wide-row spacing pattern significantly improved the leaf area index (LAI), photosynthetic active radiation (PAR), and light transmittance ratio. On the other hand, the values of stem bending resistance, the content of cellulose, hemicellulose, lignin, phenylalanine ammonia-lyase (PAL), tyrosine ammonia-lyase (TAL), and cinnamyl alcohol dehydrogenase (CAD) activities also significantly increased, and the effect of D-M4S6 was the most significant of these treatments. The D-M6S6 treatment produced the highest yield among the different treatments. Therefore, based on the planting pattern of narrow-wide-row maize-soybean intercropping, four rows of maize and six rows of soybean were more effective in improving the lodging resistance of soybean in the semi-arid region of western China.
