Published: April 2022

Abstract
This paper experimentally and numerically investigated the impact test response and characteristics of circular honeycomb cores. The experiments were conducted on two different structures of aluminum-tube honeycomb core, square structure and star structure. The specimens were tested in order to find energy absorption, specific energy absorption, and crashworthiness behaviors. The results revealed that circular honeycomb cores with star structure could resist higher impact load than circular honeycomb cores with square structure. In addition, the larger tubes showed a lower impact load the smaller tubes. It was also revealed that the greater the collapse distance of the aluminum-tube honeycomb core, the lower the load. Moreover, FEA simulation results, through ABAQUS.CAE, were compared to the experimental results. The results revealed that good agreement was achieved between the experimental results and the FEA results. The comparison results showed that the difference in maximum load between experimental and FEA model was 0.47–11.84%, which is a reliable analysis result. In terms of energy absorption and specific energy absorption, the difference in maximum load between experimental and FEA model was 23.54% and 16.23%, respectively.

Published: April 2022

Abstract
Public procurement in Iraq plays an essential function in the development and recovery of the country's economy as well as providing the essential infrastructure for the growth of the private sector. The Coalition Provisional Authority's Government Procurement Legislation No. 87 (2004) is the final procurement law in effect in Iraq. Preparations are underway for new procurement legislation as of Oct. 2021. The objective of the paper is to determine the effectiveness of the public procurement process used in a construction project in Iraq, there is also a lack of procurement methods and policy consistency between government agencies. procurement techniques, tender documentation information, Advertising deadlines, and document management procedures, for example, vary amongst federal contracting agencies. Furthermore, there is no mandatory process for the definition and disclosure of tender evaluation criteria, providing room for subjectivity in the tender award process. This paper's major conclusion that is competitive tendering is open to everyone, tendering is not mandated as Iraq's general rule, despite the fact that it is considered best practice elsewhere. Direct invitation techniques are widely used in the construction project process tendering of Iraq and if not adequately managed, they can lead to bias, fraud, and corruption.

Published: April 2022

Abstract
This work presents experimental research using draped prestressed steel strands to improve the load-carrying capacity of prestressed concrete non-prismatic beams with multiple openings of various designs. The short-term deflection of non-prismatic prestressed concrete beams (NPCBs) flexural members under static loading were used to evaluate this improvement. Six simply supported (NPCBs) beams, five beams with openings, and one solid specimen used as a reference beam were all tested as part of the experiment. All of the beams were subjected to a monotonic midpoint load test. The configuration of the opening (quadrilateral or circular), as well as the depth of the chords, were the variables studied in this study. In comparison to a solid beam, experimental results show that beams with openings have a lower load-carrying capacity not exceeding (2.3–10.6%) and higher mid-span deflection through all loading stages of elastic, service, and ultimate loads (14–73%), (19–44%), and (31–55%), respectively. Furthermore, specimens with circular openings had stiffer behaviour under load than those with quadrilateral openings. Beams with quadrilateral openings and inclined posts, on the other hand, were stiffer than beams with quadrilateral openings and vertical posts.

Abstract

Objectives
Pregnancy carries a significant risk for coronavirus disease-2019 (COVID-19) due to natural immunosuppression. A previous study from our center has shown that the lactate dehydrogenase (LDH)/lymphocyte ratio (LLR) can be used in the early diagnosis of COVID-19 and predicting mortality. Based on this, we aimed to determine the effect of LLR on early detection of critical pregnant women and mortality in COVID-19.

Methods
The data of 145 patients who were admitted to our hospital between March and December 2020; diagnosed with COVID-19 and hospitalized, were retrospectively analyzed.

Results
The median gestation period was 31 weeks (range: 5–41), 30.3% (n: 44) gave birth and 68.3% (n: 99) were pregnant. Median LLR was 0.13 (range: 0.04–0.70). The rate of cough (47% vs. 22.8%; p=0.003) was found to be high in patients with LLR>0.13. The patients were divided into subgroups. The proportion of patients without active complaints was higher in the Q1, followed by the Q4. The proportion of patients with an initial complaint of cough increased as LLR from Q1 to Q4, the distribution of other complaints did not differ between the quartiles.

Conclusions
The higher rate of cough in the group with high LLR indicates that it may be an important indicator of lung involvement during pregnancy. The highest rate of non-treatment follow-up in the lowest LLR group proved that the LLR value at the time of diagnosis can be used as an important clinical marker in pregnant women.

Abstract
Chimpanzee accumulative stone throwing at trees has been described by Kühl, H.S., Kalan, A.K., Arandjelovic, M., Aubert, F., D'Auvergne, L., Goedmakers, A., Jones, S., Kehoe, L., Regnaut, S., Tickle, A., et al. (2016). Chimpanzee accumulative stone throwing. Sci. Rep. 6: 1–8, but we lack important details about the social and ecological context for this rare behavior. Further observations may enhance future research, as the described observations have not yet been shared in the literature. We analyzed camera trap records from 2010 to 2020 of various research projects conducted in the Boé sector of Gabu Province in south-east Guinea Bissau, West-Africa, to identify ecological and social factors that might potentially influence chimpanzee accumulative stone throwing behavior (on a total of 298 records). From September 2019 until November 2019, we filmed five trees over 48 days to conduct a further exploratory study of this behavior. We discuss the importance of study design when investigating a little-described phenomenon, and the threat posed to chimpanzee populations in West-Africa by the expected expansion of mining activities. More knowledge on chimpanzee accumulative stone throwing is needed as the chimpanzee population is under stress because of increased mining activities in the area. With habitat rapidly being disturbed and destroyed, this population and its rare behavior are increasingly at risk of extermination.
When TikTok Discovered the Human Remains Trade: A Case Study
Authors: Graham Shawn , Huffer Damien , Simons Jaime 
Published: April 2022

Abstract
In the summer of 2021, a video on TikTok was heavily reposted across a variety of social media platforms (attracting conventional media attention too). Unusually (for TikTok), it was about the trade in human remains. Thus, we were presented with the opportunity to watch how knowledge of the trade exploded into broader public consciousness on a comparatively newer platform. In this article, we scrape TikTok for reactions to that moment. In our previous research on the human remains trade on Instagram, we used a particular suite of digital humanities methods to understand how Instagram was being used by participants in the trade. Here, we employ those same methods to develop a case study for contrast. The original individual, whose TikTok account is used to promote his bricks-and-mortar business buying and selling human remains, has, as a result of this attention, gained an even greater number of followers and views, making the video a “success.” Nevertheless, several users engaged in long discussions in the comments concerning the ethics of what this individual is doing. A number of users created videos to criticize his activities, discussing the moral, ethical, and legal issues surrounding the trade in human remains, which in many ways makes the “success” of this video one of fostering opposition and a wider understanding of the ethical and moral issues around this trade.

Published: April 2022

Abstract

Objectives
Cisplatin is commonly used during intraperitoneal chemotherapy however has well-established nephrotoxic side-effects. Sodium thiosulfate is often added to cisplatin-based hyperthermic intraperitoneal chemotherapy (HIPEC) protocols to mitigate this, however evidence regarding risk of hypernatraemia is scarce as of yet.

Methods
We retrospectively identified patients undergoing cytoreductive surgery (CRS) for peritoneal surface malignancies of any origin at a single high-volume unit between April 2018 and December 2020. Patients were included if they received cisplatin-based HIPEC with intravenous sodium thiosulfate. Blood tests were collected pre-surgery and then daily during admission. Hypernatraemia was defined as serum sodium >145 mmol/L. Renal impairment was defined using the RIFLE criteria.

Results
Eleven CRSs met inclusion criteria, the majority of which were indicated for ovarian cancer (72.7%). One (9.1%) patient with mesothelioma received mitomycin C as an additional chemotherapy agent. The incidence of hypernatraemia was 100% but all cases were transient, with no clinical sequelae observed. The rate of AKI was 36.4%, with three (27.3%) patients classified as risk and one (9.1%) instance of failure. No long-term renal impairment was observed.

Conclusions
Despite biochemical evidence of mild hypernatraemia but with the absence of clinical sequelae, sodium thiosulfate appears to be safe when used in adjunct to cisplatin-based HIPEC during CRS. These findings should be evaluated with further comparative studies. When describing renal impairment, it is important that standardisation in reporting occurs, with the RIFLE and Acute Kidney Injury Network criteria now the preferred consensus definitions.

Published: April 2022

To have coronary bypass surgery deliver on the claim made by Dr. Lytle in his Gibbon Lecture at the 2020 meeting of the American College of Surgeons, surgeons doing these operations must pay attention to every detail of the procedures. While a lot of attention is, appropriately, focused on sewing the distal anastomoses in coronary artery bypass operations [Tribble, 2018], there is often comparatively less attention placed on creating the proximal anastomoses for coronary artery bypass grafts. [Favaloro, 1970]. A lack of attention to these anastomoses can lead to significant problems for patients undergoing coronary artery bypass surgery. This article will address the common issues to be considered in creating proximal vein graft anastomoses in a standard coronary artery bypass operation. Let’s get started …..

Investıgatıon of the effect of ısometrıc core strength traınıng in addıtıon to basıc basketball traınıngs on explosıve power in chıldren aged 9-17
Authors: YILMAZ Nurkan 
Published: April 2022

Background and Study Aim. With its dynamic and constantly changing characteristics, basketball, which requires more than one movement, is one of the most preferred and popular team sports in the world. It is important to know that basketball requires programs based on speed, agility and strength fitness components, in which endurance and strength parameters are predominant. In this context, resistance training, which provides skill excellence and increased muscle strength, is important for basketball players. The aim of this study is to examine the effects of 4-week specific core training applied to pre-adolescent and adolescent children who do basic basketball training on explosive strength.
Material and Methods. A total of 16 [Control Group (CG): n=8; Experimental Group (EG): n=8] individuals (age 13.29 ± 1.96 years) who did not have any health problems from basketball school and continued basketball basic training were included in the study. The groups continued their usual basketball basic training program (2 days a week, 60 minutes a day). However, in addition to the basic training program, the experimental group was subjected to an isometric training program for 12-minute core strengthening. Training programs were made for a total of 4 weeks. We examined the effects of core training on speed, vertical jump and agility parameters. Statistical analyzes of the data obtained as a result of the research were obtained using the IBM SPSS 23.0 package program.
Results. There was no difference between the groups for sprint and vertical jump parameters of core and basic basketball training (p>0.05). However, there was a significant difference in favor of EG in the agility test analysis results (p<0.05). As a result, we can say that 4-week core training applied in addition to the basic basketball training program in children improves agility characteristics.
Conclusions. The findings showed that core training programs have positive effects on explosive strength parameters. In addition, strengthening the core area significantly improved the agility parameter, which is important in ground-direction changes. This, in parallel with the studies, supported that core training programs should be an integral part of other training programs. This study also showed that core stabilization training applied in a short time improves explosive strength parameters in children.

Authors: Sağın Ahmet E. 
Published: April 2022

Background and Study Aim. In this study, it was aimed to investigate the relationship between the level of interest in physical education lesson and life satisfaction of students studying in secondary schools
Material and Methods. The research group consisted of 421 students in total 52.3% (n=220) were male students and 47.7% (n = 201) were female students. Structural equation model was used in the analysis of research data.
Results. The effect of interest in physical education lesson on life satisfaction was found to be 19.8% (R2 = .198, p <0.05). In the gender variable, the effect of interest in physical education lesson on life satisfaction in girls is 12.8% (R2 = .128), whereas it is 25.7 (R2 = .257) in boys. According to the model, as the level of interest in physical education lesson of students studying in secondary school increases, their life satisfaction increases. While it is concluded that the interest level of students studying in secondary schools in physical education and sports lessons positively predicts their life satisfaction, this rate is higher in male students.
Conclusions. Since the participation of students in physical education and sports activities contributes to the multifaceted development and life satisfaction of students, it is necessary to increase the interest of students in physical education lessons and especially to engage female students. It is very important for physical education teachers to provide an environment for student participation in physical education and sports lessons. School-based interventions that can increase female students' participation and interest in physical education and sports lessons can be effective.

Published: April 2022

Rheumatoid arthritis (RA) is a chronic systemic autoimmune disorder characterized by symmetrical synovitis, progressive damage to the articular cartilage and the subchondral bone, pain, fatigue, and disabilityRecognition of RA as early as possible is important, because a significant proportion of the patients develop irreversible joint damage shortly after disease onset & risks associated with its treatment. The adiponectin is an active participant in the regulation of physiological and pathological processes, inflammatory process as mediator. This study was done to compare the progression of rheumatoid arthritis in conjunction with changes in levels of adiponectin and to evaluate its role as a prognostic marker. Analyse serum adiponectin level to evaluate its potential role to assess disease severity in patients of rheumatoid arthritis & compare its level in normal healthy control subjects. This study was conducted in MY Hospital, Indore. We enrolled 50 cases of confirmed rheumatoid arthritis patients of 20-70 years age group and 50 age and sex matched apparently healthy controls. Both cases (n=50) and controls (n=50) were assessed for haematological tests and biochemical tests, lipid profile, uric acid, CRP & adiponectin. The data were expressed as mean ± SD and analysed by using SPSS version 20. P-value of &#60; 0.05 was accepted as statistically significant. The mean age of the cases was 44.74 ± 13.10 and that of controls was 42.26 ± 8.09. Maximum number of study patients were in the age group of 31-40 years & women. The rheumatoid arthritis group was divided into subgroup according to DAS28 Score. Out of 50 cases, 2 patients (4.0%) had remission, 2 patients (4.0%) had low disease activity, 30 patients (60.0%) had moderate disease activity and 16 patients(32.0%) had high disease activity. The mean CRP in the rheumatoid arthritis group was 21.56 ± 25.46 mg/dL while in the control group was 11.09 ± 7.95 mg/L. The difference was found to be statistically significant (p&#60;0.05).The mean ESR in the rheumatoid arthritis group was 21.26 ± 8.88 mm/hour while in the control group was 15.70 ± 5.40 mm/hour. The difference was found to be statistically significant (p&#60;0.05).The mean adiponectin level in the rheumatoid arthritis group was 30.13 ± 13.04 µg/ml while in the control group was 17.08 ± 8.69 µg/ml. The difference was found to be statistically significant (p&#60;0.05).The mean adiponectin level was highest in the high disease activity subgroup and lowest in the low disease activity subgroup.In our study we concluded that patients of rheumatoid arthritis have raised level of adiponectin & CRP as compared to normal healthy control group. Adiponectin might be better marker for RA compare to CRP & ESR. Also higher levels of adiponectin were observed in patients with severe disease. Therefore, adiponectin might be used for screening which will help in predicting disease progression.
