Authors: Areef Mujawar Iram , Nagraj S. , Aaron Pravin
Published: April 2023

Introduction The angle between a horizontal line passing through C7 and a line extending from the ear tragus to C7 is known as the craniovertebral angle. This angle is a reliable measure for the identification of head and neck position. For CV angle measurement the electronic head posture instrument EHPI is used. Its measuring scale is accurate to the first decimal place and the angle is read automatically by the electronic sensor.Objectives The aim of this study was to find if there exists a relationship between load and craniovertebral angle in construction workers.Methodology The craniovertebral angle was measured and weight-correlated. Using an electronic head posture instrument the angle was measured. It consists of three components a transparent plastic frame an electronic angle finder and a camera tripod stand. On the transparent plastic frame the angle finder is placed and attached to the tripod stand. The distance to the middle of the tripod from the subjects shoulder is 0.3 m and the distance between the operatorrsquos eye and the tripod is 0.5 m. The placement was done using a measuring tape. The spinous process of C7 is palpated and an adhesive pin is placed onto it. Another adhesive pin is placed on the left ear tragus. Photograph was taken from a distance of 0.5 m until the line on the transparent plastic base was aligned with the pin markers.Result The meanplusmnstandard deviation of CV angle of male construction workers 42.21plusmn4.41 was significantly lower than the mean CV angle in female construction workers 46.09plusmn4.50. The average load kg carried by women 40.22 plusmn6.82 was lower than that carried by men 47.23plusmn5.30. The Karl Pearson method was used in order to determine if a linear relationship exists between the load kg and CV angle and an inversely proportional relationship was observed but was not significant in men r -0.049 NS and r-0.089 NS women construction workers.Conclusions To avoid problems and to prevent musculoskeletal disorders the amount of overhead load has to be minimized. Many of the musculoskeletal issues can be avoided by improving the quality of workplace environment minimizing exposure to external loads acting on the body improving job procedures coordinating work as well as educating training workers in the identification of ergonomic hazards teaching problem solving skills and enabling them to find suitable solutions.

Published: April 2023

Transcutaneous electrical nerve stimulation TENS is a modality that blocks the pain by pain gate mechanism and is documented to be safe and effective. Sternum pain signifies the pain in the thoracic cavity that contains the sternum and the cartilage connecting it to the ribs. Patients who experience pain after any cardiac surgery may also experience prolonged immobilization insufficient respiratory functions and the inability to cough as a result of the surgical procedure specifically post median sternotomy. TENS has been shown to be effective in acute and chronic pain in both medical and surgical conditions in multiple studies conducted since 1970. This review was conducted to document the effectiveness and also the parameters of TENS used post Coronary Artery Bypass Graft CABG to relieve pain and improve parameters like functional capacity cardiopulmonary endurance length of hospital stay etc. The review concluded that many studies documented the effectiveness in post-operative CABG patients however some studies stated that it was less effective than other forms of pain relief. The parameters of TENS used in all the randomised control trials have been documented in the results.The clinical application of this review is that TENS can be used as an adjunct treatment in post-operative sternal pain patients on an inpatient and outpatient basis which will be working on other parameters functional capacity cardiopulmonary endurance length of hospital stay apart from pain relief and eventually helps in improving the quality of life of the patients.

MYC is a pleiotropic transcription factor involved in cancer, cell proliferation, and metabolism. Its regulation and function in NK cells, which are innate cytotoxic lymphocytes important to control viral infections and cancer, remain poorly defined. Here, we show that mice deficient for Myc in NK cells presented a severe reduction in these lymphocytes. Myc was required for NK cell development and expansion in response to the key cytokine IL-15, which induced Myc through transcriptional and posttranslational mechanisms. Mechanistically, Myc ablation in vivo largely impacted NK cells’ ribosomagenesis, reducing their translation and expansion capacities. Similar results were obtained by inhibiting MYC in human NK cells. Impairing translation by pharmacological intervention phenocopied the consequences of deleting or blocking MYC in vitro. Notably, mice lacking Myc in NK cells exhibited defective anticancer immunity, which reflected their decreased numbers of mature NK cells exerting suboptimal cytotoxic functions. These results indicate that MYC is a central node in NK cells, connecting IL-15 to translational fitness, expansion, and anticancer immunity.

Published: April 2023

Catfish heads are a common byproduct of large-scale catfish processing, known for their
rich nutritional content. However, despite their potential to be processed into food
products such as crackers, catfish heads remain relatively underused. This study aimed to
produce crackers made from catfish heads and evaluate the nutritional, physical, and
sensory properties of the crackers. After the preparation of catfish head flour (CHF) and
catfish head crackers (CHC), the crackers were analysed with various ratios of tapioca
flour (TF) to CHF: CHC 0 (100: 0), CHC 1 (90:10), CHC 2 (80:20), CHC 3 (70:30), and
CHC 4 (60:40). The examination of the nutritional, physical, and sensory properties
showed that the CHF had high protein (30.89% db), calcium (21.83% db), and phosphorus
(10.26% db) values, with the CHC 3 having higher protein, calcium, and phosphorus
contents than the control group (p<0.05). The CHC 3 also exhibited good colours and
textures, in addition to its superiority in all sensory attributes. In light of this analysis, the
CHC 3 was indeed the best cracker processing. This study indicates that catfish heads as
food ingredients can serve as nutritious crackers preferred by the panelists.

Meat analog (MA) is an innovative, versatile food product that has a texture, colour, and
flavor which resembles beef but made from vegetable ingredients. MA can be prepared by
combining the flour of sweet potato with gluten. To enhance the colour of MA, some
colouring agents are recommended such as Monascus Fermented Durian Seed (MFDS).
This study aimed to evaluate the effect of MFDS on the physicochemical and organoleptic
properties of meat analog consisting of sweet potato flour and gluten. The experimental
design employed a Randomized Complete Block Design (RCBD) with one factor, namely
the concentration of MFDS which consist of five levels (0%, 0.2%, 0.4%, 0.6%, and
0.8%) each replicated five times. Findings revealed that MFDS had a significant effect on
colour objectively and organoleptic properties (colour preference, taste, texture), but did
not have any significant effect on moisture content and texture (hardness, cohesiveness,
springiness). The higher the concentration MFDS, the higher redness, colour preference,
and texture preference of meat analog. Based on performed organoleptic tests, the best
treatment was the addition of 0.6% MFDS which produces meat analog with moisture
content of 48.01%; lightness 54.4; redness 7.4; yellowness 13.9; chroma 15.3; o
hue 63.4;
hardness 1992.688 g; cohesiveness 0.696; springiness 0.941; and water activity (aw) 0.946.

Published: April 2023

In the internet saturated world, our lives are increasingly mediated by digital technology and algorithms. The news we read, the songs we hear and even the bills we pay are all routed to us via artificially intelligent systems. As services, occupations and aspects of daily life move online the impact of inequalities in access to digital information and its outcomes have become apparent. Machine learning already serves as the foundation for much of our digital infrastructure. The increasingly widespread application of this technology has raised concerns about its propensity to reproduce and reinforce systemic bias. Recent developments in training techniques have facilitated the release of models with broad potential application without the need for explicit training. This research explores how applications of machine learning might be designed to help facilitate more equitable access to digital information.

Published: April 2023

Lemierre syndrome is a rare thrombotic complication of head and neck infections. Nephrotic syndrome is sometimes treated by immunosuppressive medications that can present with severe infections without a fever. The association of the two diseases is extremely rare. We report the first case, to our knowledge, of Lemierre syndrome in an eleven-year-old patient with nephrotic syndrome on Tacrolimus. A patient with nephrotic syndrome is at higher risk for all kinds of thrombotic events. Also, being on immunosuppressive therapy can lead to late presentation and the absence of fever. A low level of suspicion in those patients can lead to timely diagnosis and early treatment.

Strategi ini dirancang untuk memaksimalkan energi yang disuplai oleh baterai dan superkapasitor melalui state of charge (SOC) baterai dan tegangan DC bus sehingga dapat meminimalisasi konsumsi hidrogen dan meningkatkan efisiensi keseluruhan sistem. Hasil simulasi memperlihatkan bahwa strategi ini mampu memaksimalkan kinerja baterai dan superkapasitor. Efisiensi sistem berhasil ditingkatkan menjadi 86,37% dan konsumsi hidrogen berhasil dikurangi 10% dari strategi pembandingnya. State of charge (SOC) baterai juga mampu dipertahankan untuk tetap dalam rentang batas yang telah ditentukan.Kata kunci: EMS, kereta hibrida, fuel cell, baterai, superkapasitor, optimasi ABSTRACTThe energy management strategy (EMS) in a hybrid system essentially only regulates power sharing without considering system performance optimization. This study developed an EMS based on the optimization of hybrid train with fuel cell (FC), battery, and supercapacitor power sources using the External Energy Maximization Strategy (EEMS). This strategy is intended to maximize the energy supplied by battery and supercapacitor through the SOC of the battery and DC bus voltage, thereby reducing hydrogen consumption and increasing overall system efficiency. The simulation results show that this strategy can maximize battery and supercapacitor. The system efficiency was successfully increased to 86.37%, and the hydrogen consumption was reduced by 10% when compared to the comparison strategy. The SOC of the battery can also be kept within a certain range.Keywords: EMS, hybrid train, fuel cell, battery, supercapasitor, optimization
Excessively Positive Narratives Diminish Autistic People of All Ages
Authors: Liu Nicholas
Published: April 2023

Evolving discourse about autistic individuals swims in murky territory, with ongoing debates over how the autistic community should represent itself and how the neurotypical population should engage with them. One tendency that has emerged is the depiction of autistic individuals as kind and well-intentioned but also simpleminded and guileless. This, in combination with the dominant imagery of autistic individuals as children, has created an atmosphere in which all autistic individuals are stripped of their human complexity by the neurotypical gaze, and by extension are not given the fulfillment, support, and resources needed to make possible a life of sufficient quality.
Is Accreditation, Like a Colonoscopy, Good for You
Authors: Kazemi Ellie
Published: April 2023

Accreditation is typically a voluntary process that involves a thorough evaluation of an organization’s policies, procedures, and practices. Much like a colonoscopy, the evaluation process probes deep and can be uncomfortable. With the discomfort, time, cost, and effort it takes to undergo evaluation for accreditation, the natural question is whether it is worth doing. In this paper, I will review the history of accreditation and the results of systematic literature reviews focused on the impact of accreditation. I will also discuss how accreditation may help provide quality control in behavior analysis and safeguard against service providers’ behaviors being solely shaped by funding sources, such as insurance providers. Lastly, I will provide critical questions consumers can ask to assess accrediting bodies’ transparency, objectivity, and fairness when they are seeking accreditation.

Published: April 2023

The interaction mechanisms related to the group effect between piles and between pile groups significantly influence the soil-structure interaction process. This interaction causes the superposition of stresses and, in general, makes the pile group settlement different from the settlement of an isolated pile. The objective of the present paper is to evaluate the soilstructure interaction mechanisms of buildings with foundations of monitored continuous flight auger piles (CFA) in a stratified soil mass, with the presence of an intermediate soft soil layer. Hence, it is particularly analyzed the group effect between piles of a group and the group effect between all pile groups from a foundation of a study case instrumented by means of numerical modeling, considering the effect of the soft soil layer. The results show the significant group effect on displacements, showing the increase in settlement due to the overlapping of the tension bulbs of the piles and neighboring pile groups.

Authors: Çinar İlkay , Karagöz Filiz
Published: April 2023

Background/Aim: Expression of extracellular matrix proteins and metalloproteases (MMPs) has been implicated in neoplasm recurrence. Some recent studies have suggested a correlation between matrix modifier proteins and recurrence or invasion of meningiomas. Based on previous data, the aim of this study was to find a correlation between the immunohistochemical (IHC) expression patterns of a group of matrix modifier proteins, including CD147, Matrix Metalloprotease 2 and 9 (MMP2 and 9, respectively), Epithelial Cadherin (ECAD), and Galectin-3 (GAL3) with World Health Organization (WHO)-defined grade, brain invasion, recurrence, and other clinicopathological features.
Methods: This study was a cohort study. All patients with meningioma who underwent resection over a 10-year period were identified from the electronic pathology archives. Tissue microarrays (TMAs) were created for IHC studies, and IHC staining was performed using standard methodology.
Results: A total of 231 cases fulfilled the study criteria. Histological review identified 198 grade 1 tumors (85.3%), 28 grade 2 tumors (12.6%), and five grade 3 tumors (2.2%). CD147 was determined to be positively correlated with WHO-defined grade (P=0.009). ECAD, MMP2, MMP9, GAL3 were not found to be correlated with brain invasion, recurrence, or WHO grade.
Conclusion: The study results demonstrated that CD147 could be a target for diagnosis, prognosis, and treatment of meningiomas.

The studies evaluated 60 potato varieties of different maturation groups of domestic breeding in terms of productivity, quality indicators and immunity to various types of diseases. Varieties with high productivity potential and the most adaptive to the soil and climatic conditions of the North Caucasus region were identified. In the course of the research work, the following tasks were solved:

According to the results of testing potato varieties in the conditions of the North Caucasus region, the most plastic varieties of domestic originators were identified, characterized by high yield indicators in relation to standard varieties. The yield level of more than 40 t/ ha exceeded the early varieties Meteor, Leader, Mayak, Sadon, Real. The high marketability of tubers was formed by early and mid-early varieties: Gulliver (93%), Warmas (92%), Sineglazka (92%), Samba (93%), Lukyanovsky (91%). The manifestation of macrosporiosis, on average for three years, ranged from 1.7 to 12.0%. During the growing season, the manifestation of alternariosis was up to 3.3%, the active development of late blight reached up to 50%. The most common of the viral diseases were mottled and wrinkled mosaics.

In the complex of environmental agricultural practices during of potatoes production an important place is given to the intrasoil local method of fertilizing. Technological systems for the application of this method operate as part of potato planting combined units. The use of automated technological systems for the implementation of an intrasoil local method of applying fertilizers will allow real-time dosed placement of foci of agrochemicals in those layers of the soil horizon that available for root system of plant. This will significantly reduce losses and increase the utilization rate of fertilizers while ensuring an acceptable level of environmental safety of their use and improving the working conditions of a operator. Therefore, given the random nature of the operating conditions of potato planting units, the development of an automated device for active control of the depth of placement of fertilizer foci in given horizons of the root layer the algorithm of which uses methods of predictive assessment of the state of the object is a very urgent task.

The article presents the results of assessing the content of starch in hybrid combinations of corn and the yield of starch per unit area. As a result of the study of experimental hybrids created on the basis of the VIR collection material, the selection and combination value of the initial material was revealed in terms of content in grain and yield per hectare of starch. The experiment included simple hybrids (30 combinations) obtained by a complete topcross cross scheme. Instead of crossbreeding the lines with each other, crosses were carried out with three common testers with a broad genetic basis (line, synthetic population). In the study, lines RSK 7, B 293 and a synthetic population of RNIISK 1 were used as testers. The interval of variation in the starch content in grain for the study period varied from low values to an average value and amounted to: in 2020 – 60,9 % to 65,2  %, in 2021 - from 59,3 % to 66,1 %. Lines with a high effect of GCA on the content of starch in the grain (H 46, Vz 6, Om 12, YuV 106), as well as hybrid combinations of YuV 25 / RSK 7 (63,3-64,2 %), KS 75 / RSK 7 (62,7-64,4 %), HLG 948 / RSK 7 (63,5-64,1 %), Kin 073 / RSK 7 (63,4-63,8 %), YuV 106 / RSK 7 (63,6-66,1 %), KS 25 / B 293 (63,0-63,5 %), HLG 182 / B 293 (63,5-63,6 %), KS 75 / B 293 (63,1 -63,5 %), HLG 182 / RNIISK 1 (62,9-63,6 %). The results of the study made it possible to identify experimental hybrids that form the highest yield of starch per unit area: HLG 182 / RSK 7 (3,12-3,58 t/ha), YuV 106 / RSK 7 (2,77-3,11 t/ha ), H 46 / B 293 (3,22-3,39 t/ha), Om 12 / B 293 (2,72-3,85 t/ha).
