Authors: Mitrofan Alexandru , Mandru Andreea , Pacuraru Florin
Published: January 2024

Modern patrol ships characterised by an 'axe bow' shape allows the placement of an anti-spray rail. These not only reduce drag but also minimize the wave height generated by the ship's bow. This article will present the effect of positioning of an anti-spray rail at various heights on the ship's bow to reduce drag resistance. The most favorable placement scenario will be determined through the results of numerical simulations conducted by using the commercial software Fidelity Fine Marine.

Published: January 2024

This work proposes the comparison of two models of 3D printed hip prostheses, using microscopic and chemical analysis, but also compression and bending testing. The comparison was made using a hip prosthesis designed in the Autodesk Inventor 2020 program and a model freely available on the Internet. The work includes some details about the virtual prototyping of prostheses and results from the chemical analysis of the components of the hip prostheses, carried out using an X-ray spectrometer to identify the elements contained in the PETG (polyethylene terephthalate glycol) material that was used to obtain the samples. The second method of analysis was the microscopic one and finally the samples were subjected to external forces, through bending and compression testing. This comparison aimed to demonstrate the dependence between the shape of the prosthesis and the mechanical properties of the analysed samples.

Lasso and Group Lasso with Categorical Predictors: Impact of Coding Strategy on Variable Selection and Prediction
Authors: Huang Yihuan , Tibbe Tristan , Tang Amy , Montoya Amanda
Published: January 2024

Machine learning methods are being increasingly adopted in behavioral research. Lasso regression performs variable selection and regularization, and is particularly appealing to behavioral researchers because of its connection to linear regression. Researchers may expect properties of linear regression to translate to lasso, but we demonstrate that this assumption is problematic for models with categorical predictors. Specifically, we demonstrate that while the coding strategy used for categorical predictors does not impact the performance of linear regression, it does impact lasso’s performance. Group lasso is an alternative to lasso for models with categorical predictors. We investigate the discrepancy between lasso and group lasso models using a real data set: lasso performs different variable selection and has different prediction accuracy depending on the coding strategy, while group lasso performs consistent variable selection but has different prediction accuracy. Using a Monte Carlo simulation, we demonstrate a specific case where group lasso tends to include many variables when few are needed, leading to overfitting. We conclude with recommended solutions to this issue and future directions of exploration to improve the implementation of machine learning approaches in behavioral science. This project shows that when using lasso and group lasso with categorical predictors, the choice of coding strategy should not be ignored.

The alteration of mechanical properties because of moisture is an inevitable problem in the practical use of cellulosic materials, as well as green and high-performance materials synthesized based on cellulose. Although researchers have analyzed and reported this issue from various aspects, it is necessary to report the variation of mechanical properties of the cellulose system and its causes in detail from the molecular level as well. Herein, the effect of moisture content on the mechanical properties of cellulose is methodically examined by molecular dynamics methods. The main reasons for the structural changes caused by the stiffness and activity space of the cellulose chains and the number of hydrogen bonds in the system are explained and discussed. The obtained results reveal that, in the simulated range of moisture content, low moisture (0 to 4%) exhibits a positive effect on the mechanical properties of the amorphous cellulose region, whereas the effect of high moisture content (4 to 8%) is negative. The mobility of cellulose chains first reduces and then intensifies as the number of water molecules increases, while the rigidity of the corresponding system first increases and then decreases. Additionally, the free volume of the system increases first and then decreases as the number of water molecules rises. The mechanical properties of the amorphous region of cellulose are proportionally correlated with the number of hydrogen bonds in the system. Based on these results, a moisture content of 2% can enhance the properties, increasing the H-bond density in the cellulose network.

Agricultural waste leads to a number of environmental issues, including pollution and environmental degradation. In Nigeria, Zea mays husk is one of the most prevalent agricultural wastes, and it can be turned into a valuable resource of quality cellulose. The goal of this study was to establish a low-cost and sustainable chemical treatment method for isolating cellulose from Z. mays husk feedstock. A series of alkaline delignification, digesting, and bleaching techniques were used to extract and purify cellulose. TAPPI T203 OS-74, TAPPI T222 OS-83 and TAPPI T222 OM-02 methods were used to determine the cellulose, hemicellulose and lignin contents, respectively. The samples were also characterised by scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy (FTIR), and CHNS/O analyses. The resulting product was found to contain 97.95% α-cellulose, 0.19% β-cellulose, and 1.86% γ-cellulose. The presence of 40.95% carbon, 2.98% hydrogen, 0.72% nitrogen, 0.07% sulphur, and 55.28% oxygen was found by the CHNS/O analysis of cellulose. The untreated husk microscopy displayed an uneven, flake-like, and non-uniform surface, whereas the delignified husk, digested husk, and pure cellulose (ZMH-C) micrographs revealed, respectively, a smooth non-uniform surface, an irregular porous surface, and a smooth wool-like surface. The FTIR spectra of the treated samples demonstrated an increase in the intensity of the polar property of the OH group, as well as the elimination of the hemiacetal group and β-1,4-glycosidic linkages. The ZMH-C diffractogram verified the existence of characteristic 2θ peaks of cellulose at 220, 240, and 300, as well as a 4.7% crystallinity index. The comparatively low-temperature sequential alkaline delignification, digesting, and bleaching method adopted extracted low-lignin crystalline cellulose material from Z. mays husk. The flexibility, biodegradability, and availability of husk make it a viable source of high-quality cellulose with several possible applications. Z. mays cellulose has been thus demonstrated to be an appealing material for a wide variety of industries seeking environmentally acceptable and sustainable solutions.

The incorporation of TEMPO-oxidized cellulose nanofibers (TOCNs) derived from wood pulp resulted in an improvement in the characteristics of polymeric membranes made up of poly (methyl vinyl ether maleic acid)/PMVEMA and poly (ethylene glycol)/PEG. The membranes were constructed, and TOCNs were included in the formulation at a rate of 5 wt%. TOCNs were categorized as either short or long, depending on the aspect ratio measurement. According to the findings of the research, the various lengths of TOCNs resulted in variances in the optical transmittance properties, contact angles, and whiteness level of the membranes, in addition to a little variation in the tensile and thermal properties of the material. When compared to short TOCNs, long TOCNs offer somewhat improved performance in terms of optical transmittance, whiteness level, tensile characteristics, and thermal stability. The results of this study reveal the significance of the morphology of nanocellulose in determining the properties of the composite that includes it. Thus, the characteristics of the target membrane were greatly influenced by nanocellulose morphology.

"Hepatocellular carcinoma (HCC) is a fatal malignancy with a poor prognosis. There is an urgent need to study the molecular mechanisms of HCC development and explore potential drugs to improve survival. This study aims to investigate the antitumor effects of astaxanthin on HCC proliferation, migration, invasion and apoptosis through regulation of adenosine-activated protein kinase (AMPK). CCK8, wound healing, transwell and flow cytometry assays were used to evaluate Hep 3B cell viability, migration, invasion and apoptosis after astaxanthin treatment. Protein expression was determined by Western blot. CCK8 assays showed that all concentrations (200 μM, 400 μM, 500 μM) of astaxanthin used in this study significantly inhibited the proliferation of Hep 3B cells (P < 0.05). Wound healing, transwell and flow cytometry showed that astaxanthin inhibited Hep 3B cell migration and invasion and induced apoptosis. Western blot showed that astaxanthin increased the expression of p-AMPK (P <0.05) and inhibited its downstream p-mTOR protein expression (P < 0.05). The effects of astaxanthin on cell proliferation, migration, invasion and apoptosis was attenuated after addition of the AMPK blocker Compound C. To conclude, astaxanthin inhibits the proliferation, migration and invasion of HCC by regulating AMPK, and promotes tumor cell apoptosis in a dose-dependent manner."

"Food packaging is intended to protect food and extend its shelf life, but it may affect food quality and safety because of chemical migration. Food quality and safety regarding packaging is a significant global concern. Legislations have an essential role in providing regulatory guidance on quality assurance systems and verifying their implementation as a means of regulatory compliance. The large number of various materials used in the manufacture of packages complicates the evaluation of food–packaging interactions. This review is an overview of literature data on the effects of printed food packaging on the migration of chemicals into foods, as well as on various migration sources of chemical compounds. Various aspects, such as the interaction between packaging and food starting with the production process of food packaging to food–packaging contact during storage, the effects of primary and secondary packaging on chemical migration, permeability of packaging materials, inkinduced migration in printed packaging, and types of transition from packaging to food, were examined in detail. Besides, studies on subjects such as the food contact materials analysis used to test the phenomenon of migration in foods and migration limits have been discussed. Moreover, studies on the use of recycled paper in packaging and its effect on migration, ink chemicals resulting from recycling and studies on this subject are included. Information is given on measures to reduce the effect of migration, low migration of printing inks, coatings and adhesives, and materials used in barrier applications. In line with this research study, suggestions were made for measures to reduce the harmful effects of chemical migration on human health and to prevent the risk of migration from packaging to food."

"Papyrus (Cyperus papyrus L.) is a lignocellulosic plant suitable for many applications when properly pretreated. This study explores the potential of a two-stage pretreatment (combining hydrothermal and chemical methods) on the characteristics of cellulose fibers derived from papyrus. One-stage and two-stage pretreatments were compared, utilizing sodium hydroxide (NaOH) and ferric chloride (FeCl3) chemical solutions at a 3% (w/v) concentration. Chemical pretreatment was employed for one-stage processing, while hydrothermal pretreatment was introduced prior to chemical pretreatment. As the liquid hot-water process intensified, significant changes in chemical composition and morphology occurred. Hydrothermal pretreatment partially eliminates hemicelluloses and lignin, while increasing the cellulose content and enhancing fiber crystallinity. Following the pulping and bleaching stages, it was determined that the FeCl3-based two-stage pretreatment exhibited the greatest potential for cellulose recovery and hemicelluloses and lignin removal, yielding the highest crystallinity index."

"Quality attributes of tissue products establish important differentials in the current scenario of fierce competition. Although the formation of the tissue paper is not monitored in industrial processes, it is imperative to recognize its importance for developing quality properties. A theoretical analysis of influences of the fiber morphology and furnish composition on the prediction of mass distribution uniformity in the paper forming process is presented. The theory utilizes the Poisson distribution for the grammage probability of points on the sheet, taken as a random fibrous network. The simulations revealed that lower grammage coefficients of variation could be achieved with total or predominant addition of eucalyptus fibers in mixtures with Pinus spp. fibers. The results provide meaningful insights into the understanding of how the selection of fiber type and pulp blend could help in achieving suitable structural uniformity of the sheet, in the forming process, in view of the expected paper quality."

This article explores an easy and economically viable route for cellulose fibre isolation from the stem of Pennisetum polystachion and its utility as reinforcement filler in the polymer matrix for the development of biocomposites. The cellulose fibre was isolated by alkali treatment, followed by chlorine free bleaching using hydrogen peroxide. The SEM and FTIR analyses revealed removal of hemicelluloses and lignin. The X-ray diffraction analysis showed increased crystallinity and the TGA and DTG curves indicated greater thermal stability of the isolated fibre compared to the raw fibre. The cellulose fibre was used as reinforcement in ethylene propylene diene monomer (EPDM) rubber to prepare biocomposites. The cure characteristics and mechanical properties of the composites were investigated. The maximum torque and the mechanical properties varied by the addition of the filler in the matrix. The SEM images of the composites showed good adhesion of the cellulose fiber in the EPDM matrix. The biodegradability of the composites was confirmed by the soil burial test. The test revealed that the percentage degradation in tensile strength increased with filler loading, indicating that the composites are environmentally friendly and biodegradable.

Quantum computing is an emerging technology in which quantum mechanical properties are suitably utilized to perform certain compute-intensive operations faster than classical computers. Quantum algorithms are designed as a combination of quantum circuits that each require a large number of quantum gates, which is a challenge considering the limited number of qubit resources available in quantum computing systems. Our work proposes a technique to optimize quantum arithmetic algorithms by reducing the hardware resources and the number of qubits based on ZX calculus. We have utilized ZX calculus rewrite rules for the optimization of fault-tolerant quantum multiplier circuits where we are able to achieve a significant reduction in the number of ancilla bits and T-gates as compared to the originally required numbers to achieve fault-tolerance. Our work is the first step in the series of arithmetic circuit optimization using graphicalrewrite tools and it pavesthe way for advancing the optimization of various complex quantum circuits and establishing the potential for new applications of the same.

Published: January 2024

Extraosseous Ewing's sarcoma (EES) is a malignant mesenchymal tumor much rarer than its intraosseous counterpart.
Few case reports of EES have been published in the literature. Only one in ve cases of Ewing's sarcoma occurs as
Extraskeletal. The use of magnetic resonance imaging helped diagnose, plan procedural interventions, assess neoadjuvant chemotherapy
effectiveness, and detect local recurrences and metastatic spread of the tumor. Immunohistochemical markers further differentiated the diagnoses.
EES should be considered when evaluating soft tissue lumps of neoplastic characteristics, in children or adolescents. Early detection of EES is
essential.

Published: January 2024

Uncommon in the clinical setting with no denite etio-pathogenesis, Hirayama disease (HD), also referred to as non
progressive juvenile spinal muscular atrophy usually unilateral, is characteristically seen in young adolescent males in the
east. We report a case of a 19-year-old male with asymmetric amyotrophy of distal upper limb with oblique atrophy and reverse split hand
syndrome. He was diagnosed to be a sporadic case of typical HD, in an early plateau phase according to the Tashiro guidelines as well as the latest
Huashan Diagnostic Criteria. Early intervention with physiotherapy and hard cervical collar showed no progression of disease after 12 months'
follow-up. Clinicians should be vigilant about myriad of unusual presentations of HD in daily practice.

Aim/ Purpose:- To assess the diagnostic accuracy of Computed tomography in evaluating the spectrum of various
etiologies ( extrinsic, intrinsic, and intraluminal cause), point of obstruction (transition point), and complications of
Intestinal obstruction. To predict the need for surgical intervention in various cases of intestinal obstruction. Methods:- This is a retrospective
observational study that comprises 50 patients with suspected Intestinal obstruction from October 2022 to September 2023 and they will be
evaluated on the basis of various causes of intestinal obstruction and its complications using various imaging modalities ( Plain radiograph/
Ultrasonography and Computed Tomography) and relevant clinical history. MDCT improves dia Results:- gnostic condence in detecting
Intestinal obstruction and its grade, point of obstruction (transition point), and causes. We found the most common cause of bowel obstruction is
adhesions and other common causes are neoplasms, Crohn's disease, volvulus, intussusception, paralytic ileus, and tubercular etiology. 50
patients with bowel obstruction were evaluated on MDCT, and 10 out of them were managed conservatively their etiologies were paralytic ileus
and intussusception. Out of 35 operated patients whose etiologies were adhesions, volvulus, intussusception, CT ndings matched with
intraoperative ndings in 28 patients. CT ndings were highly signicant for predicting Conclusion:- the main surgical outcome, including
degree of obstruction, and the presence of transition zone and mesenteric congestion. MDCT is the preferred modality to evaluate panoramically
patient presents with intestinal obstruction for early decision for surgical intervention to prevent complications.

A COMPARATIVE STUDY OF GALLBLADDER DISSECTION DURING LAPAROSCOPIC CHOLECYSTECTOMY BY ULTRASONIC BIPOLAR DISSECTION VERSUS MONOPOLAR ELECTROCAUTERY
Authors: Hajong Ranendra
Published: January 2024

Background: Laparoscopic cholecystectomy (LC) is the 'gold' standard treatment for benign gallbladder diseases.
Dissection of gallbladder from its bed is an important step during LC which is often complicated by gallbladder
perforation leading to the spillage of bile or gallstones into the peritoneal cavity. This may lead to unwanted complications with the resultant
delay in the duration of the procedure. The aim of this study was to compare the usage of ultrasonic bipolar dissection and electrocautery for
dissection of gallbladder from its bed and to assess the various intra-operative parameters and the resultant consequences thereof. This Methods:
was a prospective analytical type of cross-sectional study conducted in the department of General Surgery in a tertiary care hospital in North East
India from January 2021 till June 2023. A total of 192 patients undergoing elective laparoscopic cholecystectomy were divided into two equal
groups of 96 patients each with the even numbered patients allocated to electrocautery group and odd numbered patients were allocated to
ultrasonic bipolar dissection for gallbladder dissection. The main outcome measures were gallbladder perforation, number of patients requiring
lens cleaning and the total operating time. Data were collected in the Microsoft Xcel, 2010 and analysed by using SPSS, Version 23. A p value of
≤ 0.05 was considered statistically signicant. The overall rate of gall Results: bladder perforation was 20.83% (12.5% in the ultrasonic bipolar
group and 29.17% in the monopolar group). The number of patients requiring lens cleaning and also the number of times of lens cleaning
required per patient was signicantly lower in the ultrasonic bipolar dissection group (p value 0.003). The overall duration of surgery was
signicantly shorter in the ultrasonic bipolar dissection group (23.25 ± 5.82 minutes versus 37.63 ± 9.46 minutes). The use of Conclusion:
ultrasonic bipolar dissection for gallbladder dissection from its bed during laparoscopic cholecystectomy when compared with monopolar
electrocautery have the following advantages- decreased incidence of gallbladder perforation, lesser number of lens cleaning due to less smoke
generation and shorter duration of operation.
COMPARATIVE STUDY OF THE SERUM TISSUE PLASMINOGEN ACTIVATOR(T-PA) LEVELS IN DIABETIC PATIENT WITH AND WITHOUT FOOT ULCER.
Authors: T P Elamurugan , Saini Abhishek
Published: January 2024

Background: Diabetic foot ulcer is associated with signicant microangiopathy which causes damage to the vascular
endothelial cells leading to increased risk of thrombus formation along with impaired process of brinolysis. tPA is the
most important part of the brinolytic system. It has been proven that the level of tPA in the blood reects brinolytic activity. Hence t-PA levels
can be used to identify patients who have microangiopathy and are at risk of developing diabetic foot ulcer To compare the . Objective:
concentration levels of serum tissue plasminogen activator (t-PA) levels in Diabetic patients with and without foot ulcer. Materials and
methods: This study was conducted in the Department of General Surgery during the period October 2017 to May 2019. Serum Tissue
plasminogen activator (tPA) levels in Diabetic patients with and without foot ulcer were assessed and compared. All the demographic parameters
studied were also compared with mean tPA and their signicance were analyzed. Results: A total of 85 patients with Diabetic foot ulcer and 85
Diabetic patients without foot ulcer were recruited in the study. Median tPA levels (ng/ml) in a diabetic patients with and without foot ulcer was
3.7 and 4.6 with a statistical signicance (p value=0.005). Mean tPA levels in patients who presented with and without gangrene among ulcer
group was 3.17±1.05 and 4.52±1.69 respectively(p value<0.001). Mean tPA levels in ulcer group who had Wagner's grade of ≤2 and >2 were
5.87±1.79 and 3.51±1.09 respectively. (p value<0.001). Tissue plasminogen activator (t-PA) concentrat Conclusions: ion is signicantly lower
in diabetic patients with foot ulcer. Lower concentration of t-PA is associated with microangiopathy complications like foot gangrene and higher
