Authors: Bakshi M P S , Wadhwa M
Published: February 2024

Samples of 26 species of forest tree leaves and 10 species of wild grasses commonly fed to livestock in the semi- hilly arid zone of Punjab State were collected at 30 day interval for 12 months. The tree leaves as compared to grasses had higher CP, EE and acid detergent lignin content, while reverse trend was observed with respect to NDF, ADF, cellulose and hemicelluloses content. The mineral profile revealed that calcium, magnesium and copper content was higher, while zinc content was lower in tree leaves as compared to grasses. But the phosphorus, iron, manganese and cobalt content was observed to be statistically comparable. The calcium and magnesium content in both the tree leaves and grasses was much higher than the requirements for dairy cattle, but both were highly deficient in P, and most of the trace elements. The antimetabolites like total tannins, condensed tannins and hydrolysable tannins were higher in tree leaves as compared to grasses by 83.2, 98.8 and 75.7%, respectively. The condensed tannins as per cent of total tannins were higher in tree leaves, while hydrolysable tannins as per cent of total tannins were higher in wild grasses. The water soluble oxalate content was comparable in tree leaves and grasses, but the concentration was much lower than the toxic level of 4%. The digestion kinetic parameters for DM and NDF also revealed that tree leaves were degraded at faster rate and had higher effective and true degradability. The rumen fill was lower in tree leaves as compared to grasses predicting higher voluntary dry matter intake in tree leaves. It was concluded that the tree leaves had greater potential as alternate feed resources as compared to wild grasses.

Photovoltaic systems play a pivotal role in renewable energy initiatives. To enhance the efficiency of solar panels amid changing environmental conditions, effective Maximum Power Point Tracking (MPPT) is essential. This study introduces an innovative control approach based on an Artificial Neural Network (ANN) controller tailored for photovoltaic systems. The aim is to elevate the precision and adaptability of MPPT, thereby improving solar energy harvesting. This research integrated an ANN controller into a photovoltaic system in order dynamically optimize the operating point of solar panels in response to environmental changes. The performance of the ANN controller was compared with traditional MPPT approaches using simulation in Simulink/Matlab. The results of the simulation showed that the ANN controller performed better than the traditional MPPT techniques, highlighting the effectiveness of this method for dynamically changing solar panel performance. The ANN particularly demonstrates higher precision and adaptability when environmental conditions vary. The strategy consistently achieves and maintains the maximum power point, enhancing overall energy harvesting efficiency. The integration of an ANN controller marks a significant advance in solar energy control. The study highlights the superiority of the ANN controller through rigorous simulations, demonstrating increased accuracy and adaptability. This approach not only proves effective, but also has the potential to outperform other MPPT strategies in terms of stability and responsiveness

Published: February 2024

According to recent research, it is studied that the second most common cause of death for women worldwide is breast cancer. Since it can be incredibly difficult to determine the true cause of breast cancer, early diagnosis is crucial to lowering the disease's fatality rate.  Early cancer detection raises the chance of survival by up to 8 %. Radiologists look for irregularities in breast images collected from mammograms, X-rays, or MRI scans. Radiologists of all levels struggle to identify features like lumps, masses, and micro-calcifications, which leads to high false-positive and false-negative rates. Recent developments in deep learning and image processing give rise to some optimism for the creation of improved applications for the early diagnosis of breast cancer. A methodological study was carried out in which a new Deep U-Net Segmentation based Convolutional Neural Network, named UNDML framework is developed for identifying and categorizing breast anomalies. This framework involves the operations of preprocessing, quality enhancement, feature extraction, segmentation, and classification. Preprocessing is carried out in this case to enhance the quality of the breast picture input. Consequently, the Deep U-net segmentation methodology is applied to accurately segment the breast image for improving the cancer detection rate. Finally, the CNN mechanism is utilized to categorize the class of breast cancer. To validate the performance of this method, an extensive simulation and comparative analysis have been performed in this work. The obtained results demonstrate that the UNDML mechanism outperforms the other models with increased tumor detection rate and accuracy

The Role of Internal Audit Units in Managing Corruption Risksin Egyptian Government Authorities
Authors: Bahig Metwaly Mohamed , Moharram Algarhy Farid
Published: February 2024

Corruption, a persistent global challenge, undermines public trust, hinders development, and erodes the credibility of government institutions. This research examines the vital role of internal audit units (IAUs) in mitigating corruption risks within government authorities. Drawing on case studies and relevant theoretical frameworks, we explore how IAUs, through their independent and objective assessments, can contribute to enhancing transparency, accountability, and ethical conduct within government bodies. We analyse how IAUs, by evaluating internal controls, financial processes, and procurement practices, can identify vulnerabilities, detect potential irregularities, and recommend corrective measures to minimize opportunities for corruption. Further, we investigate the effectiveness of various IAU methodologies in combating corruption, including data analytics, fraud risk assessments, and whistle-blower protection mechanisms. The research also critically examines the challenges faced by IAUs, such as lack of independence, inadequate resources, and political interference. Finally, we propose recommendations for strengthening the effectiveness of IAUs in preventing and detecting corruption, including enhanced collaboration with external oversight bodies, capacity building for internal auditors, and fostering a culture of integrity within government institutions.

Implementation of a Hybrid Power Testbed Model of a Hybrid Electric Unmanned Aerial Vehicle
Authors: Fouellefack Lionel
Published: February 2024

Testbeds form an essential aspect in the construction of a Hybrid – Electric Unmanned Aerial Vehicle (HE – UAV)/Aircraft. Such testbeds have never been developed before even though a model of the HE – UAV was developed. This article explores the feasibility of implementing a prototype of a (HE – UAV) testbed. Several research papers in the domain were thoroughly explored and the results were grouped based on similar research findings. The grouping was done in terms of the sizing result achieved by each author, the UAV class used, the hybrid powertrain specifications of the components, and the testbed equipment used to construct the HE – UAV testbed. The result from this research shows that a HE – UAV testbed can be achieved if stringent measures are done in determining the size of the component for a given drone size and a careful selection of the components from the sizing result for the testbed construction.

Authors: M. Umar Bashir
Published: February 2024

Intraabdominal abscesses continue pose challenge to surgeons due to their rather ominous presentation. Most often, high index of suspicion is required to initiate a diagnostic workup. The discovery of a wide variety of antibiotics, more aggressive surgical drainage techniques, intensive care management, and other factors have decreased mortality below 25% over the past century. Recently, more conservative, less invasive source control techniques have recently been developed. These include laparoscopic, needle, and percutaneous image-guided drainage techniques. This chapter will discuss the epidemiology of intraabdominal abscesses including frequency of occurrence of the various types and age and sex distribution. Relevant anatomy of the peritoneal cavity will be given. Risk factors will be discussed. Classification will include intraperitoneal, solid organ abscesses and retroperitoneal abscesses. Pathology and pathophysiology of the various types of abscesses will be discussed followed by clinical presentation, morbidity and complications. Aetiology and bacteriology of the abscess types will be elaborated. A discussion will be provided on resuscitation, patient evaluation and preoperative workup. Management will be discussed as follows: Overview, percutaneous image-guided drainage vs. open drainage, (including indications, anaesthesia, access and technique of drainage), pearls and postoperative/postprocedural care and complications. Prognosis of each abscess type will be given.
Perspective chapter: Emotional Intelligence from a Neuropsychological Perspective
Authors: Miranda Marcos Rubén , Brénugat Lindsay , Bague Kévin , Laurent Éric
Published: February 2024

Social cognition enables the processing of information necessary to evolve within a social group. Neuropsychology explores models linking brain networks to social information processing. Social cognition is closely tied to the concept of Emotional Intelligence (EI), defined as the mental ability involved in accurately perceiving, understanding, using, and regulating one’s own emotions and those of others. EI could explain the variability of socially guided behavior. Therefore, EI seems to be an interesting concept for neuropsychologists. EI abilities are summarized, showing the neuroanatomical correlates, the tools enabling their assessment, and the functional impact in everyday life. Perceiving emotions in others, alexithymia, empathy, emotional memory, decision-making, theory of mind, and mind regulation are neuropsychological processes than can be explained through the lens of the concept of Emotional Intelligence. Creating standardized tools to assess perception, identification, emotional regulation skills, establishing emotional intelligence profiles, and comparing them to rational intelligence should contribute to enhancing our comprehension of social interactions and their associated dysfunctions.

Published: February 2024

Plants undergo a wide range of morphological, cellular, anatomical, and physiological changes in response to salinity stress. However, plants produce some signaling molecules, usually known as phytohormones, to combat stress conditions. Salinity tolerance is a complex mechanism, whereas phytohormones have a central role in it. Phytohormone-mediated plant responses improve nutrient uptake, the source-sink relationship, and plant growth and development. Phytohormones triggers the specific gene expressions which are responsible for the modification of various plant mechanisms under salinity stress. This review summarized the most recent research findings about plant responses to salinity stress at physiological and molecular levels and discussed the probable function of several (abscisic acid, indole acetic acid, cytokinins, gibberellic acid, salicylic acid, brassinosteroids, ethylene, and triazoles) phytohormones and their interaction in modulating salinity stress. Further, the understanding of specific genes involved in phytohormonal regulation toward salinity tolerance is a key to developing breeding and transgenic approaches for meeting food demand under sustainable crop production.
Colorectal Cancer: Colonoscopy and Follow Up
Authors: Aloul Adnan Al , Valentin Varlas
Published: February 2024

Pelvic recurrence is a significant concern following curative resection for rectal cancer, regardless of the tumor’s origin of the rectum. In this retrospective observational study, 219 patients were analyzed, with 213 undergoing surgical treatment for rectal cancer at three surgical centers between 2014 and 2019. Surgical procedures included anterior resection with Hartmann’s procedure (39 patients), anterior resection of rectosigmoid with colorectal anastomosis (130 cases), and abdominoperineal resection (44 cases). After a 2-year follow-up, pelvic recurrence occurred in 19 patients, constituting approximately 8.9% of cases. The recurrence rates varied among surgical procedures, with a 15.38% recurrence rate after the Hartmann procedure, 9% after abdominoperineal resection, and 7% after anterior resection of rectosigmoid with colorectal anastomosis. Emphasize the high recurrence rates associated with advanced stages of rectal cancer. Notably, its follow-up was done clinically, by laboratory tests, colonoscopy (the main test for pelvic recurrence) after 6 months of surgery, 12 months, and 2 years, computed tomography (CT), magnetic resonance imaging (MRI), and pelvic ultrasound at one year and 2 years, a lower recurrence rate being indicative of a successful curative surgical treatment. The Hartmann procedure, often performed as an emergency operation for locally advanced lesions, exhibited the highest recurrence rate.

Published: February 2024

Ultra-High Pressure Homogenization (UHPH) is an emerging non-thermal technology that uses continuous pumping at 200–600 MPa (generally 300), and then the fluid is depressurized against a special valve made with highly resistant alleys and coated with diamond powder. The UHPH process is able to sterilize grape juice or whatever food fluid and at the same time is extremely efficient in inactivating oxidative enzymes. The total elimination of wild microorganisms in grape juice allows the perfect implantation of the selected Saccharomyces cerevisiae starter facilitating the expression of particular metabolic profiles or the expression of specific extracellular activities. Furthermore, the use of complex emerging biotechnologies such as the use of co-inoculations with S. cerevisiae and lactic acid bacteria to perform simultaneously alcoholic and malolactic fermentations works much better if the initial juice has a very low load of wild microorganisms. Additionally, the development of spoilage processes by wild microorganisms that can remain in the wine after fermentation is practically impossible when the initial juice is treated by UHPH. Thus, UHPH helps to obtain wines more stable from a microbiological perspective and therefore safer and more hygienic.
Quercetin: A Potential Drug Candidate for Inflammatory Bowel Disease
Authors: Li Mingrui , Gao Yun
Published: February 2024

Over the past decades, the incidence rate of inflammatory bowel disease (IBD) has significantly risen all over the world. Most of the patients with IBD suffer from severe symptoms and complications. Being an autoimmune disease, recent research indicates that certain factors, such as environmental changes, disturbances in intestinal microbiota, abnormal immune responses, and genetic susceptibility, play a role in the pathogenesis of IBD. Nevertheless, the precise cause of IBD remains ambiguous. Therefore, there is no known cure for IBD. Moreover, traditional medications have troublesome side effects. For these reasons, some phytochemicals with more tolerance and less adverse effects capture the interest of medical scientists. Flavonoid, a natural anti-inflammatory compound, has recently been validated for its efficacy in IBD treatment. Among the extensive flavonoid family, comprising over 5000 members, quercetin has emerged as a promising drug candidate for treating IBD, supported by substantial preclinical evidence. Currently, quercetin participates in regulating IBD through several pathways, such as antioxidant properties, improvement of the intestinal barrier, modulation of the microbiota, immune response, and regulation of the enteroendocrine system in the gut. In brief, quercetin, a natural compound with anti-inflammatory activity, demonstrates a huge potential as a candidate drug for IBD treatment.

Cardioprotection Using Doxorubicin: The Role of Dexrazoxane
Authors: J. Krone Ronald , Merchant Azim , D. Mitchell Joshua
Published: February 2024

Doxorubicin is among the most effective chemotherapeutic agents, and is active against a wide variety of cancers. However, it also is highly cardiotoxic so that any effective use of this agent requires a strategy to limit the toxicity. Dexrazoxane is the only drug approved specifically to counter the cardiac toxicity of doxorubicin because of its ability to interfere with the molecular mechanisms causing the cardiac injury. Although other mechanisms, namely iron chelating properties, were originally thought to be responsible for its cardiac protection, recent studies suggest that dexrazoxane’s interaction with topoisomerase II, an enzyme important for the function of DNA during mitosis is most likely the major mechanism. While it had been thought that the mechanism of doxorubicin’s cardiac toxicity and the mechanism of doxorubicin’s tumor effectiveness are different, more recent studies have suggested that some of the most important mechanisms are similar. Because of this uncertainty, dexrazoxane is underutilized in patients where it could be useful. Thus, studies comparing tumor efficacy in patients taking doxorubicin randomized to dexrazoxane comparing progression-free survival and mortality as well as cancer treatment-related cardiac dysfunction (CTRCD) are needed to give oncologists data to support aggressive use of dexrazoxane in their patients.

Neurofeedback (NFB) is a closed-loop technique in which the patient receives feedback on brain activity to encourage voluntary control of brain activity. NFB promotes neuroplasticity and changes the brain functionally and structurally. Motor imagery-based NFB (MI-NFB) can improve motor imagery ability by providing feedback on brain activity during motor imagery, thereby showing effectiveness in performance and motor learning. Furthermore, the effects of MI-NFB are further enhanced when it is combined with noninvasive brain stimulation and motor exercise. Therefore, MI-NFB is used in the physiotherapy of patients with neurological diseases, such as stroke and Parkinson disease, as well as children with attention deficit-hyperactivity disorder and elderly people. This chapter reviews MI-NFB in physiotherapy practice, thus contributing to the development of effective evidence-based physiotherapy.
