High-Isolated Full-Duplex Dongle Antenna Based on Even-Mode Suppression for B5G Communications
Authors: Da Yiran , Chen Xiaoming , Zhang Aofang , Wei Kunpeng , Kishk Ahmed A.
Published: May 2023

A space-shared full-duplex antenna with high isolation is proposed for universal serial bus (USB) dongles. A compact antenna with a compact size of 22 mm x 4 mm comprises a loop and dipole antennas, working as a vertical monopole and a horizontal dipole, respectively. The dipole-type is fed by a microstrip-slotline transition with filtering characteristics of odd-mode bandpass and even-mode bandstop, avoiding the even-mode excitation for the loop antenna. The inherent isolation is caused by the orthogonality of the modes and the even-mode suppression (caused by the microstrip-slotline transition). Thus, high port isolation, low envelope correlation coefficients (ECC), and high efficiency are achieved across the 5G band of 3.4-3.6 GHz.

Published: May 2023

Background and Aim: Chronic kidney disease (CKD) is one of the most important diseases in cats. This study aimed to compare the ultrasonographic kidney length-to-abdominal aortic diameter (K/AO) ratio between healthy and CKD cats and investigate the correlation between K/AO and blood results.

Materials and Methods: Fifteen healthy cats and 15 CKD cats were included in this clinically prospective study. All cats were evaluated for radiographic and ultrasonographic K, radiographic K-to-second lumbar length ratio (K/L2), and K/AO, indirect systolic blood pressure and plasma creatinine (Cr), blood urea nitrogen (BUN), and symmetric dimethyl arginine (SDMA).

Results: The radiographic and ultrasonographic kidney lengths of CKD were significantly shorter than those of healthy cats (p < 0.05 and p < 0.05, respectively). The average K/L2 and K/AO were significantly lower in CKD than in healthy cats (p < 0.01 and p < 0.001, respectively). The K/AO had a strong negative correlation with plasma Cr (r = −0.7682, p < 0.0001), BUN (r = −0.6175, p < 0.001), and SDMA (r = −0.589, p < 0.001). However, K/L2 had a moderate negative correlation with plasma Cr (r = −0.5866, p < 0.001), BUN (r = −0.4884, p < 0.01), and SDMA (r = −0.5404, p < 0.01). The optimal cutoff value of K/AO (<10.71) had higher sensitivity and specificity than K/L2 for identifying feline CKD.

Conclusion: Kidney length-to-abdominal aortic diameter could be a better and more promising parameter than the K/L2 ratio for evaluating kidney size in cats with CKD.

Keywords: cats, chronic kidney disease, kidney length-to-abdominal aortic diameter, renal length, ultrasonography.
Fluid Hyperthermia and Ultrasonic Studies on Nickel Ferrite Magnetic Nanoparticles
Authors: Ammani Ammal V. Beula Shanthi , Jebarathinam N. John
Published: May 2023

Superparamagnetic nickel ferrite (NiFe2O4) nanoparticles were synthesized by low temperature
hydrothermal method using EDTA as templating agent. The synthesized nanoparticles were
characterized by FTIR, XRD, FESEM and TEM analysis. The XRD analysis shows the presence of
cubic spinel phase with crystallite size of 26.42 nm. The morphology analyzed by FESEM and TEM
techniques indicate the presence of cubical shape particles having average particle size of 28.44 nm
with no agglomeration. The VSM analysis gives “S” shape curve with zero coercivity and saturation
magnetization (Ms) of 30 emu/g indicating the presence of small magnetic particles exhibiting the
superparamagnetic behaviour. Nickel ferrite nanofluids were prepared by mixing carrier fluid water
with varying amounts of nickel ferrite nanopowder. Zeta potential measurements of dilute solution of
nickel ferrite show the formation of stable nickel ferrite nanofluids. Hyperthermia and ultrasonic
studies were carried out on various concentrations of nickel ferrite nanofluids. The SAR values and
ultrasonic parameters were calculated. Less concentrated nickel ferrite nanofluids quickly attain
threshold hyperthermia temperature of 43 °C when exposed to lower applied AC magnetic field of
range 5 mT to 20 mT. Ultrasonic studies show at lower concentrations nickel nanoparticles interact
with carrier fluid water through cohesive forces mainly hydrogen bonding and keep the particles in an
isolated state there by continue to exhibit superparamagnetic characteristics. At higher concentrations,
particle-particle interaction predominantly occurs leading to increase in particle size beyond 30 nm,
so that the magnetic characteristics of nickel ferrite nanoparticles changes from superparamagnetic to
ferromagnetic nature. At low concentrations induction heating occurs through Neel and Brownian
relaxation mechanism whereas at high concentrations hysteresis loss mechanism operate to attain the
threshold temperature of 43 ºC.

Published: May 2023

A straightforward synthetic procedure for thioamides has been developed at 100 ºC using pyrazole
aldehyde, a secondary amine, precipitated elemental sulphur and DMSO as solvent. The
Willgerodt-Kindler reaction was successfully carried out by increasing the mole ratio of the precipitated
sulphur and amine derivatives. The synthesized thioamides derivatives were characterized by 1H and
13C NMR, FT IR, HRMS spectrometric techniques. This method has various advantages, including
high yields, a relatively rapid reaction time and the ability to operate in catalyst-free conditions.

Published: May 2023

Anionic surfactants in the river, particularly downstream in Delhi, have created massive foam-like
conditions which may be harmful to aquatic life and humans that come in contact. The present study
focussed on the quantification of anionic surfactants, biological contaminants in terms of total bacterial
count, total and faecal coliform bacteria and qualitative analysis of pathogenic bacteria from the samples
acquired from different sites of Yamuna river. The concentration of anionic surfactants was observed
to be between 0.42-3.89 mg L-1 at Okhla barrage, which was significantly high as compared to Wazirabad
barrage and ITO bridge. The total bacterial count of Okhla barrage was observed more as compared to
Wazirabad barrage and ITO Bridge ranging between 9.7 × 106 to 9.1 × 108 CFU/mL. The findings of
total coliform bacteria were observed to be consistently high at Wazirabad barrage ranging between
1.3 × 103 to 9.0 × 104 MPN/100 mL. Qualitative analysis of pathogenic bacteria showed the presence
of P. aeruginosa, Salmonella sp., E. coli and S. aureus. Based on the results obtained in the study, it
was inferred that the water quality of Yamuna river at Wazirabad barrage, ITO Bridge and Okhla
barrage was poor and thus requires regular monitoring and call for immediate effective mitigation
strategies.Anionic surfactants in the river, particularly downstream in Delhi, have created massive foam-like

it's in vitro Activity for Biomedical Applications
Authors: Stella S. Mary , Vijayalakshmi U.
Published: May 2023

In present work, the composites of hydroxyapatite with polyvinyl alcohol (PVA) and polyvinyl pyrrolidone
(PVP) were prepared and analyzed for its biodegradability and hemocompatibilty. The individual and
the combined combination of polymers with hydroxyapatite (HAP-PVA, HAP-PVP and HAP/PVA-PVP)
were characterized by FT-IR, XRD, SEM-EDAX and TGA-DSC analysis. The crystallinity and
functional groups of hydroxyapatite (HAP) was confirmed by XRD and FT-IR analysis. The SEM
analysis displayed rod shaped morphology and the formation of apatite layer was confirmed by simulated
body fluid (SBF) immersion. The Ca/P ratio of the SBF immersed composite was found to be increased
to 1.71. This reveals that the polymer in the composite acts as a nucleating site for the development of
carbonated hydroxyapatite which chemical composition resembles with natural bone. The hemolysis
rate for the composite consisting of HAP/PVA-PVP was found to be less than 3% than the composite
consisting of HAP with PVP. Based on these results, it can be concluded that the HAP/PVA-PVP
nanocomposite offers superior alternatives in the field of biomedicines.
Cu(II) and Fe(III) Catalyzed Synthesis of Novel Thiophene Hybridized
Thiadiazolyl Schiff Bases (TTS) as COX-2 Selective Inhibitor
Authors: Mishra Geeta , Dwivedi Parmesh K. , Verma Neeraj , Srivastava Sajal , Singh Ashok K , Chaturvedi Devdutt
Published: May 2023

A novel series of thiophene hybridized thiadiazolyl Schiff bases (TTS) were designed and synthesized
using copper nitrate (CuII) catalyzed synthesis of Schiff bases and their subsequent ferric chloride
(FeIII) catalyzed cyclization into thiadiazoles. The design of molecules was inspired by the
well-documented anti-inflammatory properties of thiadiazoles, Schiff bases and thiophene. Based on
information from mass spectroscopy, IR, 1H and 13C NMR measurements, the structures of the recently
synthesized compounds were determined. The purpose of molecular docking was to better understand
the interactions between drug candidates and COX-1 (PDB ID: 3KK6) and COX-2 (PDB ID: 3Q7D)
inflammation-related targets. Compounds 3a-f showed a more stable binding complex with COX-2
(-8.09 to -9.13 kcal/mol) when compared to COX-1 (-4.86 to -5.94 kcal/mol). Additionally, the
carrageenan-induced rat paw oedema model was used for the in vivo analysis and compound 3a
demonstrated excellent anti-inflammatory activity when compared to the reference drug, diclofenac.
Interestingly, the mRNA expression analysis using qRT-PCR demonstrates a specific suppression of
COX-2 as compared to COX-1, further supporting the earlier findings. Altogether, the findings could
provide an opportunity for these compounds to be developed as novel lead molecules for rational
alternatives of NSAIDS.

Authors: Sarmah Pingal , Gogoi Sonit Kumar
Published: May 2023

Herein, a simple solvothermal synthesis of graphitic carbon nitride nanosphere (g-CNN) at 180 ºC is
reported. The photocatalytic activity of g-CNN was studied under an in-house developed white light
emitting diode (WLED) reactor and characterized by FESEM, PXRD, FTIR, EDX, UV-visible
spectroscopy and BET isotherm. The g-CNN has absorbance in visible light region and exhibits
enhanced photocatalytic activity compared to bulk graphitic carbon nitride (BGCN) for
photodegradation of methylene blue, which attributes to its lower surface area. The photocatalytic
performance of g-CNN as function of pH of dye solution and catalyst amount were also studied. The
g-CNN can be used for three repeated cycles with minimal change in photocatalytic efficiency. The
solvothermal synthesis method at relative low temperature introduces terminal oxygen functionalities
in g-CNN, which enhance light absorption and accelerate electron transfer results in improvement of
photocatalytic efficiency of g-CNN. The results demonstrated the effectiveness of g-CNN as a
photocatalyst for the treatment of water using visible light from WLED.

Authors: AKTAŞ Burak Nedim
Published: May 2023

The implementation and long-term sustainability of high-performance work systems (HPWS) are both examined in this review of the literature. The review emphasizes the value of taking multiple factors into account, including leadership, organizational culture, continuous improvement, employee engagement, and sustainability from HPWS's point of view. In addition, it examines the difficulties organizations face in preserving HPWS over time and how these difficulties can be solved for long-term viability. Researchers interested in understanding the implementation and upkeep of these systems as well as managers and practitioners seeking to implement HPWS in their organizations may find the review to be a valuable resource. More studies are required to improve the comprehension of the long-term sustainability of HPWS since there has not been much research conducted in this area. Moreover, it has been noted from the review that the majority of the studies have been carried out in the context of large organizations, and more research is required to examine the long-term sustainability of HPWS in various business sectors.

Published: May 2023

Zusammenfassung Hintergrund: Patienten mit unilateralen Hirnschäden zeigen häufig eine kontraversive Lateropulsion (»pusher syndrome«, PS). Prismenadaption (PA) führt zu einer Neuausrichtung des propriozeptiven und visuellen Koordinatensystems und könnte daher eine wirksame Behandlungsoption für das PS sein. Methode: Das Studiendesign bestand aus einer Serie von Einzelfallinterventionen (n=14) mit vor- und nachheriger Baseline Messung. Patienten in einem subakuten Zustand nach einem zerebrovaskulären Ereignis der rechten Hemisphäre und mit einem mindestens moderatem PS (gemessen anhand der Klinischen Skala für Contraversive PusherSymptomatik (SCP) und einer Abweichung der Sitzbalance zwischen der linken und rechten Körperhälfte von mindestens 10 Prozent) wurden eingeschlossen. Die quantitativ gemessene Veränderung der Gleichgewichtsverteilung beim Sitzen war der primäre Outcome Parameter. Nach drei Baseline-Messungen im Abstand von drei Tagen (Tage 1, 4, 7) folgten die Interventionssitzungen mit PA im Abstand von drei Tagen (Tage 10, 13, 16). Nach 14 Tagen (Tag 30) wurde eine Folgemessung durchgeführt. Wir erhoben auch den Kraftgrad, den Frührehabilitation Barthel-Index (FRBI) und die Functional Independence Measure (FIM) am Tag 1 und zum Zeitpunkt der Nachfolgeuntersuchung. Die Lokalisation der Läsion wurde manuell in den MRIcron-Standard-Hirnatlas übertragen. Ergebnisse: Jede PA-Intervention verbesserte das Sitzgleichgewicht signifikant, was auf eine sofortige Wirkung von PA auf PS hindeutet. Die PA-Effekte nahmen jedoch über den Zeitraum von drei Tagen teilweise wieder ab, und, wie die Baseline-Phase zeigte, es trat eine signifikante Erholung auch unabhängig von PA auf. Die Patienten verbesserten sich auch in der SCP, dem FRBI, der FIM und der Muskelkraft. Aufgrund der generell hohen Remission kann nicht geschlossen werden, dass letztere Verbesserungen mit den PA-Interventionen zusammenhingen. Die Patienten zeigten überlappende Läsionen im rechten Putamen, im präzentralen Gyrus und in der Corona radiata. Schlussfolgerung: PA führte zu einer kurzfristigen Verbesserung der kontraversiven Lateropulsion, die aber womöglich als Nacheffekt der PA zu interpretieren ist. Es bleibt damit unklar, ob sie sich auch nachhaltig auf die Erholung vom PS auswirkt Schlüsselwörter: Schlaganfallrehabilitation, Prismenadaption, Pusher-Syndrom, Lateropulsion, Sitzbalance

Authors: Batubara Lusiana
Published: May 2023

Background: Vitamin D (25(OH)D) is a fat-soluble secosteroid hormone that plays a major role in bone mineralization and other metabolic processes in the human body. A complex between biologically active vitamin D (1,25(OH)2D) and its receptor serves as a transcription factor for various genes involves in bone homeostasis. Several studies have been link vitamin D deficiency with a reduction in Bone Mineral Density (BMD), but the result was still conflicting. However, data regarding vitamin D deficiency in the Indonesian population are rarely available.Objective: The study aims to assess vitamin D status and its correlation with Bone Mineral Density (BMD) among Javanese elderly women.Methods: A cross-sectional study was conducted in 75 healthy Javanese elderly women aged 60-84 years old. Serum Vitamin D was measured by enzyme link immunoassay using 25(OH)D ELISA kit. BMD was measured by dual-energy X-ray absorptiometry (DXA).Results: Mean±SD serum 25(OH)D level of the study population was 14.97±6.6ng/mL, we found that 73.3% were vitamin D deficient and 26.7% did not. There is no correlation between vitamin D and BMD lumbar, femoral neck or T-score (p=0.064, -0.215; p=0.443, -0.090; and p=0.109, -0.187 respectively). Lower BMD lumbar, femoral neck and T-score was correlated with increased age (r=-0.238, p=0.040; r=-0.377, p=0.001; and r=-0.295, p=0.010 respectively) and decreased BMI (r=0.525, p=0.000; r=0.516, p=0.000; and r=0.520, p=0.000 respectively).Conclusion: From this study, we concluded that vitamin D deficiency was prevalent among Javanese elderly women. However, there is no correlation has been found between vitamin D status and bone mineral density in this population.

Published: May 2023

In the backdrop of COVID19 recovery, Pakistan is still struggling to cope with the economic challenges and disruptions caused in the energy supply chain. On one hand where COVID has brought serious socio-economic costs and prolonged delays, it has also provided opportunity for developing countries such as Pakistan to “build-forward-better” their economies in a more sustainable and climate friendly manner. This study particularly highlights the impact of COVID on energy supply and demand sectors of Pakistan, its near- and long-term impacts, and what policy interventions can be adopted to put Pakistan on-track to achieve its Nationally Determined Contributions (NDCs). The economic focus in on “Green Recovery” and what key interventions will foster a rapid transition towards decarbonization in Pakistan. Low Emission Analysis Platform (LEAP) model is used to provide energy sector outlook (2020-2040) of Pakistan under different scenario i.e., Pre COVID growth, Business-as-Usual, Slow Recovery, and Green Recovery from COVID. The results obtained from the model depicts that following a green recovery scenario, Pakistan can reduce around 10 Mtoe (9%) of its total energy use, 53 TWh of electricity, 19 Mt of emissions from demand sectors, and 11 Mt of emissions from the power sector by 2030. For total levelized cost of the power sector, the green recovery scenario represents a generation cost of $13 billion by 2030 which further highlights that energy efficiency could lead to cost savings of approximately $3 billion each year by 2030. Green recovery is however still a daunting task as it would require economic stimulus of $8 billion only to recover to its pre COVID scenario and total investments of $120 billion by 2030.

Published: May 2023

This study focuses on the synthesis of silver/copper bimetallic nanoparticles (Ag/Cu BMNPs) using Seidlitzia stocksii stem aqueous extract. The synthesized product was characterized by powder X-rays diffraction techniques (XRD), Fourier transform infrared spectroscopy (FTIR), Energy dispersive X-rays spectroscopy (EDX), Scanning electron microscopy (SEM). The bimetallic nature of the particles was confirmed by XRD whereas the elemental composition was verified by EDX analysis. FTIR and SEM were used to determine the presence of different functionalities and morphology of the prepared BMNPs respectively. The photocatalytic degradation of methylene blue was analyzed using solar light. Nearly 44 % degradation was observed for 70 min of irradiation with excellent rate constant. Results revealed that the synthesized material is a potential candidate in the field of photocatalysis. Moreover, this may be contributed to presence of BMNPs. It may be concluded that the prepared material could be applied as cost effective and ecofriendly catalyst for the degradation of toxic pollutants from industrial effluents.
Structure and properties of 3D resorbable scaffolds based on poly(L-lactide) via salt-leaching combined with phase separation
Authors: Ito Masashi , Okamoto Masami
Published: May 2023

In tissue engineering, polymer-based scaffolds play an important role via cell adhesion, proliferation, and tissue regeneration in three-dimensional (3D) structures, exhibiting great potential in a variety of tissues. For fabrication of scaffolds, the particulate-leaching method and thermally-induced phase separation (TIPS) are popular procedures. However, a complete interconnectivity of the porous structure has not been ensured. We have prepared PLLA-based 3D scaffolds with high porosity by the combination of TIPS with NaCl salt-leaching technique. Interconnectivity and cellular infiltration were improved by humidity treatment in the preparation of the scaffolds. By optimization of the parameters of scaffold pore morphologies and cellular penetration, potent 3D resorbable polymeric scaffolds using combinatory method was demonstrated.

This study aims to characterize the productivity of basement aquifers based on a database built by pumping test and drilling report from eighteen boreholes exploited in Bagoue region of Cote d’Ivoire. By using last version of a tool to assist in pumping test interpretation suggested by the French Mining and Geological Survey, Transmissivity parameter values of confined aquifers were determined through the well-known Theis method. In the same approach, critical yield value of borehole was determined at the equivalence point of linear and quadratic pressure drop from short-term pumping test data. Geostatistical analysis and kriging of transmissivity of aquifers were realized. Then, it was elaborated few predictive equations between hydrodynamic and hydraulic parameters based on their relationship level. Comparison of aquifers productivity and boreholes hydraulic capacity ended the methodology. Transmissivity ranged from 9.10-7 to 4.10-5 m2.h-1 while specific yield of boreholes reached between 0.34 and 23.07 m3.h-1. Yields from exploited boreholes varied between 0.5 m3.h-1 and 12 m3.h-1 with an average reaching 3.44 m3.h-1. Critical yield varied between 2.11 and 18.8 m3.h-1 with an average of 6.95 m3.h-1. According to geostatistical analysis of Transmissivity, its spatial spreading adjusted spherical model with a range reaching 0.13 meters. Findings highlighted 44 % of aquifer areas characterized by low value of transmissivity with great value of exploited outflow. That suggests a short-term availability of drinking water for living communities. In the same way, 11.11 % of boreholes were established into aquifer areas characterized by great transmissivity and low outflow values that suggests a better supply environment with long-term groundwater availability.

Bivalves are known to exhibit wide morphological variations, which are closely linked to their ecology and reproductive activity. Therefore, the study of growth is necessary to model population dynamics, which, in turn, is crucial to support the exploitation and management of the stock. The current study aimed to analyze the shell morphological variations in the bivalve Ark shell Arca noae collected monthly from the Bizerte lagoon (northern Tunisian coasts) from October 2013 to September 2014. Allometric relationships established between linear variables (shell length and height); weight variables (total weight) and the relative growth between variables (isometry vs allometry) were analyzed. All morphometric relationships were highly significant with high correlation coefficients (R2: 0.604-0.903). Seasonal monitoring of the linear and weight relationship of the A. noae population suggested the presence of a negative allometric growth during the seasons which indicated that Ark shells are growing faster in length than in height and weight. Overall, linear and weight growth in A. noae from the Bizerte lagoon was found to be uniform and synchronous over the seasons and seems not to be influenced by the species’ reproductive cycle. This preliminary study will be useful for further research studies in biology, ecology and stock management of this non-exploited marine resource.
A rare presentation of multifocal tuberculosis in an immunocompetent patient
Authors: Ben Mansour Amani
Published: May 2023

Introduction: Multifocal tuberculosis (MT) is an uncommon presentation in immunocompetent patients. It’s associated more with an immune-depression like Human Immunodeficiency Virus infection. We report a case of MT with presternal cold abscess, mediastina and cervical adenopathy, bone, and vertebral location that occurred in an apparently immunocompetent patient. Case presentation: A 19-year old woman with no previous history of tuberculosis (TB) exposure was admitted for chronic chest pain lasting for 13 months. She presented with a history of fever, night sweat and weight loss (09 kg). The first clinical examination noticed a voluminous presternal abscess. The chest X-Ray showed an enlargement of the middle mediastinum associated to pleural effusion opacity, but any active pulmonary lesions. A computed chest tomography revealed the presence of a parietal mass centered on the sternum, with extension in the soft parts, bone lies of the sternal manubrium, lies of the vertebral hemi-bodies of T10 and T11, cervical lymph nodes, phrenic mediastina and sub-pectoral nodes with peritoneal and mesenteric involvement. Magnetic resonance imaging of the spine showed tiered thoracic lumbar and sacral spondylitis with paravertebral and anterior epidural collections responsible for spinal cord compression next D10 without signs of spinal cord pain. The draining of the cold abscess revealed some whitish pus, in which acid-alcohol resistant bacilli were identified. There was no history of diabetes, renal failure, or long-term treatment with corticosteroids or immunosuppressant’s: HIV serology and viral hepatitis were negative. The blood glucose was normal. The patient was treated with anti-tuberculosis regimen based on: Ethambutol, Rifampicin, Isoniazid, and Pyrazinamide for two months, and then rifampicin and isoniazid for seven months. The outcome was good with the disappearance of the abscess and all the radiological signs. Conclusion: Multifocal TB such as the case reported are uncommon and confined mostly to immunocompromised patients especially those with HIV infection. Because of the clinical polymorphic features of multifocal TB, the diagnosis is usually difficult to make, resulting into delay before beginning of the adequate treatment.
A load sharing principle in abdominal wall reconstruction follow-up & case report: Strattice biologic mesh without the presence of adhesions
Authors: Nguyen Christie Huynh , Shadid MD Alexander , Dickinson Brian P
Published: May 2023

Background: The senior authors previously published a paper on abdominal wall reconstruction using Strattice acellular dermal matrix demonstrating effective aesthetic and functional results. Despite the common and effective use of Strattice acellular dermal matrix for abdominal wall reconstruction, insurance companies do not universally approve its usage. Critics of its usage state that its intra-abdominal effects are unknown. Purpose: To further demonstrate that Strattice acellular dermal matrix is a safe and durable method to reconstruct the abdominal wall with maximal outcomes, minimal intra-abdominal morbidity, and adhesion formation. Methods: A retrospective chart review was done on our patient who underwent abdominal wall reconstruction of a ventral hernia with component separation and placement of Strattice acellular dermal matrix several years prior. The patient happened to develop appendicitis several years post abdominal wall reconstruction, requiring laparoscopic appendectomy. Photographic analysis was used to document the Strattice and absence of adhesions. Results: Strattice acellular dermal matrix was successfully used in the underlay intra-abdominal position to reinforce a midline hernia repair and external oblique component separation. At three years post hernia repair, the patient had no evidence of hernia. CT-scan demonstrated well opposed rectus abdominus muscles. On laparoscopic examination of the intraperitoneal cavity during appendectomy, there was no evidence of bowel adhesions to the abdominal wall or Strattice acellular dermal matrix. The Strattice was lined with peritoneum. Conclusion: Successful repair of primary and recurrent abdominal hernia with Strattice acellular dermal matrix is effective. In our experience, the production of adhesions between the bowl and the intraperitoneal placed Strattice is low.

Background and aims

Self-exclusion in gambling disorder (GD) is considered a measure to decrease the negative consequences of gambling behavior. Under a formal self-exclusion program, gamblers request to be banned from accessing to the gambling venues or online gambling.

The aims of the present study are

1) to determine sociodemographic characteristics of a clinical sample of seeking-treatment patients with GD who are self-excluded before arriving at the care unit; 2) to identify personality traits and general psychopathology of this clinical population; 3) to analyze the response to treatment, in terms of relapses and dropouts.

Methods

1,416 adults seeking treatment for GD, who are self-excluded completed screening tools to identify GD symptomatology, general psychopathology, and personality traits. The treatment outcome was measured by dropout and relapses.

Results

Self-exclusion was significantly related to female sex and a high sociodemographic status. Also, it was associated with a preference for strategic and mixed gambling, longest duration and severity of the disorder, high rates of general psychopathology, more presence of illegal acts and high sensation seeking rates. In relation to treatment, self-exclusion was associated with low relapse rates.

Conclusions

The patients who self-exclude before seeking treatment have a specific clinical profile, including high sociodemographic status, highest severity of GD, more years of evolution of the disorder and high emotional distress rates; however, these patients' presents better response to treatment. Clinically, it could be expected that this strategy could be used as a facilitating variable in the therapeutic process.

Published: May 2023

The importance of dual-energy computed tomography in the diagnosis of gout, the principles of dual-energy computed tomography, the accuracy of the methodology, and the types of artifacts are discussed in this study. The possible dependence of the presence of deposits of sodium monourate on other clinical data and the role of dual-energy computed tomography in the differential diagnosis of other crystalline arthropathies are considered.
The dual-energy computed tomography has several advantages, including noninvasiveness, speed of execution, and a significant reduction in the risk of iatrogenic consequences compared with diagnostic arthrocentesis, which is the gold standard in diagnosing gout. Dual-energy computed tomography can accomplish gout detection, treatment, and differential diagnosis.

Published: May 2023

Helium is an importantnatural resourceand it hasgreat importance for scientific research. It is currently extracted mainly from natural gas or inlarge air separation units. Heliumandneonareusually separatedfrom an separationcolumntogether. In order to obtain pure neon and helium they are further purified. This article discusses the main methods of extracting helium from the neon-helium mixture.Having compared rectification, freezing, membrane separation and sorption methods, the authors concluded that the adsorption method allows separation at relatively high temperature intervals and is more energy-efficient than the other methods considered. The paper presents existing examples of the application of the adsorption method for the purification of helium from neon, which have been implemented in Chinaand in the CIS. An overview of adsorption separation on new adsorbents, both on metal-organic bases and on single-walled carbon nanotubes, is also presented. In the future, the authors will conduct experiments to fill in the data gaps on adsorption and desorption of neon-heliummixture on different adsorbents.

Published: May 2023

The article discusses the prerequisites and natural consequences of the control methods development in engineering systems: (1) a simple deviation and perturbation controller, (2) a fuzzy logic controller with a fuzzifier and a rule base, (3) a neural network controller for dynamically adjusting the coefficients of the corresponding links, (4) a discrete neural network controller with a neural approximator and controller. The experience gained by researchers and engineers since the first description of the principles of regulation in 1910 and the level of information technologies design, in particular the neural network method of machine learning and the enormous computing potential of computer devices, today can be integrated into a fundamentally new method of discrete neural network regulation.
The review carried out in the article is aimed at identifying and demonstrating the significance of experimental and operational data, which must be properly structured and marked up at the stage of their collection and archiving. It is this approach that will allow us to quickly implement neural network controllers in engineering systems, since the most important stage for their creation is the process of learning and optimizing the architecture of neural networks.
The principle of operation, advantages and disadvantages, the optimal stages of a neural network controller improvement based on two neural networks for the formation of a control strategy, taking into account the most probable state of the system at the next point in time, are given.

Published: May 2023

Background: Counselling and rapid referral to a specialised facility might be improved with the use of a scoring system that could diagnose ovarian cancer. The relative simplicity of the Risk of Malignancy Index (RMI) scoring technique and the ease with which it may be applied make it a strong candidate to use as a primary diagnostic tool for individuals with pelvic masses.
Methods: Prospective observations study conducted on women diagnosed with ovarian mass by clinical examination and confirmed by ultrasonography, undergoing surgery at RL Jalappa Hospital, Kolar from January 2021 to December 2022. Histopathological report was considered as Primary outcome parameter. Age group, Parity, Menstrual history, Risk Malignancy Index, etc., were considered as explanatory parameters.
Results: A total of 40 subjects are included among which 22.50% are aged ≤40 years and 77.50% are aged >40 years. Using a cut off of 25, majority (88.2%) of those with malignancy had RMI≥25 and in benign histopathology report 56.5% had ≥25 RMI. Histopathology report, there was a statistically significant (p<0.05) difference in RMI values. The RMI had a sensitivity of 88.24% in predicting malignancy with specificity 43.48%, positive predictive value 53.57%, negative predictive value 83.33% with a total diagnostic accuracy of 62.50%.
Conclusions: Results from RMI and histopathology correlate positively. The results of this research show that RMI is a reliable and practicable method for assessing patients with pelvic masses at the commencement of therapy and identifying those who are good candidates for centralised surgical treatment.
