Authors: Renzi Federica , Reitano Elisa , Franca Davanzo , Chiara Osvaldo , Cimbanassi Stefania 
Published: September 2021

AbstractAlcohol and drugs misuse represents an important social problem. There is no agreement about influence of ethanol and drugs on trauma severity and clinical course. The aim of this study was to investigate the impact of alcohol and drugs abuse on road related trauma managed to our Level I Trauma Center. Data of 1067 car or motorcycle drivers consecutively admitted in a 5 years period were retrospectively analyzed. The sample was divided into two groups: patients with alcohol and/or drugs misuse and patients without detectable plasmatic levels or not screened because no clinical suspicion of these substance. Demographic data, mechanism of trauma, severity of injury, daily and season time of trauma distribution, alcohol and drugs levels and outcomes were retrieved. Alcohol or drugs misuse were detected in 242 patients. Heavy alcohols levels were the 62.3%. Among drugs cannabis was the most detected substance. These patients were significantly younger than the overall study population (p = 0.011), with a higher ISS (p = 0.012) a lower RTS (p = 0.047), a lower GCS (p = 0.005) and an higher head injuries severity (p = 0.030). Regarding time distribution, Saturday was the day with the highest percentage of trauma associated with substance misuse (21%). Alcohol/drugs misuse plays a very important role in the epidemiology of road related trauma. Despite the higher severity of trauma scores and the higher incidence of severe head injuries in patients with alcohol or drugs consumption, there were no effects of this substances on mortality of injured patients involved in road crashes.
Recommendations and Nutritional Considerations for Female Athletes: Health and Performance
Authors: Holtzman Bryan , Ackerman Kathryn E. 
Published: September 2021

AbstractOptimal nutrition is an important aspect of an athlete’s preparation to achieve optimal health and performance. While general concepts about micro- and macronutrients and timing of food and fluids are addressed in sports science, rarely are the specific effects of women’s physiology on energy and fluid needs highly considered in research or clinical practice. Women differ from men not only in size, but in body composition and hormonal milieu, and also differ from one another. Their monthly hormonal cycles, with fluctuations in estrogen and progesterone, have varying effects on metabolism and fluid retention. Such cycles can change from month to month, can be suppressed with exogenous hormones, and may even be manipulated to capitalize on ideal timing for performance. But before such physiology can be manipulated, its relationship with nutrition and performance must be understood. This review will address general concepts regarding substrate metabolism in women versus men, common menstrual patterns of female athletes, nutrient and hydration needs during different phases of the menstrual cycle, and health and performance issues related to menstrual cycle disruption. We will discuss up-to-date recommendations for fueling female athletes, describe areas that require further exploration, and address methodological considerations to inform future work in this important area.
Dynamics of Glyphosate and Aminomethylphosphonic Acid in Soil Under Conventional and Conservation Tillage

Published: September 2021

Abstract
This study investigates the adsorption and dissipation of glyphosate and the formation/dissipation of AMPA in non-tilled (NT) and conventionally tilled (CT) soil at 0–5 and 5–20 cm depth. Glyphosate adsorption was mainly related to the different NT and CT soil properties (clay and amorphous Al oxides), whereas an effect of the soil management could not be identified. Glyphosate dissipation was initially fast, and it slowed down later. The initial glyphosate concentration in NT soil at 0–5 cm was significantly lower than the dose applied due to the interception by the weeds and crop residues. AMPA began to form early after treatment and persisted longer than glyphosate. The DT50 range was 8–18 days for glyphosate and 99–250 days for AMPA. Longer glyphosate and AMPA DT50 were observed in NT soil compared to CT soil but, for glyphosate, the difference was significant only at 5–20 cm. Higher glyphosate and AMPA concentrations were detected in NT than in CT soil at the end of the study at 0–5 cm. The differences in glyphosate and AMPA DT50 and persistence were mainly attributable to the influence of different NT and CT soil characteristics. However, other factors could have contributed to the different glyphosate and AMPA dynamics between the soils, like glyphosate wash-off from crop residues on NT soil with the rainfall, the delayed glyphosate return to the soil by weed root exudation or weeds decomposition, and the NT soil compaction which may have reduced the microbial degradation of glyphosate at low concentrations.

Map Symbols in Video Games: the Example of “Valheim”
Authors: Horbiński Tymoteusz , Zagata Krzysztof 
Published: September 2021

AbstractThe main focus of this article is to examine the interpretation of twelve cartographic symbols on the map in Valheim. The authors set the research goal: to investigate how players and non-players interpret the symbols. The Valheim video game, which was released in 2021, is a survival game set in an open world. The authors noticed that game developers did not provide a direct explanation of the map symbols used, which could result in a different interpretation and experience of the game. The authors adopted a survey on the LimeSurvey platform as research methodology. This survey tool was used to gather information on experiences and interpretations of map symbols among a diverse group of respondents. Using online forums allowed one to disseminate the survey to a large audience of players from all over the world. Then, using the categorisation method for individual questions, a large database of respondents’ answers was created. Through the analysis, the authors checked the interpretation of symbols and presented the results in the form of graphs. Then, using statistical tests, they analysed the relationship between individual symbols. The study reveals that there are intergroup differences in responses to symbols directly related to the game. With more complicated symbols that did not emphasise an unambiguous answer, both groups of respondents had a problem with indicating the meaning of the symbol. For future research, it is worth continuing research on the interpretation of various map symbols not only in games, but also in all cartographic products.

Published: September 2021

AbstractThis paper discusses the rate of hydration of magnesia (CCM1 and CCM2) during the formation of magnesium hydroxide with magnesium acetate and distilled water. The influence of magnesium acetate and the reactivity of the two types of caustic calcined magnesia were studied by thermogravimetric analysis, differential scanning calorimetry, mass spectrometry, particle size detection and pH. Also, both citric acid and acetic acid test were done to measure the reactivity of magnesium oxide powder. The results indicate that the hydration rate of both oxides in magnesium acetate system are vigorously exothermic compared to the water system. The study shows mechanistically that magnesium acetate enhanced the degree of hydration of magnesium oxide due to the presence of acetate ions and Mg2+ ions when it compared to water. Mathematical models confirm the findings.
The modified mini-open Maffulli's technique for repairing open Achilles tendon laceration using fiber wires with calcaneal fixation. A prospective case series of 14 patients
Authors: Nguyen Luong Van 
Published: September 2021

ABSTRACT

Introduction:
Open Achilles tendon laceration was managed surgically by wound irrigation, debridement and Achilles tendon repair. The poor vascularization at the midsection of Achilles tendon and surrounding skin, extensile open approaches were factors, that contributed to higher complication rate of wound healing and infection. We had not seen a report of minimal invasive repair techniques for treatment of open Achilles tendon injury.

Material and methods:
Between January 2018 and May 2020, 14 patients with open Achilles tendon laceration had been enrolled in the study and underwent the modified Maffulli's procedure at the Central Military Hospital 108. The characteristics of the patients, ATRS score AOFAS score and complications were recorded.

Results:
No wound infection was encountered in our series. The range of ankle movement was restored in all patients. After one year post-operatively, the ATRS score was 92.2 ± 1.5 (range: 90–96), and AOFAS score was 97.4 ± 1.8 (range: 92–100). All patients could return to their work and their light sporting activities at the time of 16.7 ± 2.5 weeks (range, 14–20) and 19.8 ± 4.6 weeks (range: 17–25) postoperatively, respectively. 14 out of 14 patients were able to perform single heel raise.

Conclusion:
We showed the modified Maffulli's technique using fiber wire with calcaneal fixation for repairing open Achilles tendon laceration to be a safe and reliable method without increasing financial cost and specially designed tools.

Level of evidence:
Level IV, a prospective case series study.

Published: September 2021

Background
Effects of pancreatectomy on glucose tolerance have not been clarified, and evidence regarding the difference in postoperative glucose tolerance between pancreaticoduodenectomy (PD) and distal pancreatectomy (DP) is lacking.

Study design
This prospective, single-center observational study analyzed 40 patients undergoing PD and 29 patients undergoing DP (Clinical trial registry number UMIN000008122). Glucose tolerance, including insulin secretion (Δ C-peptide immunoreactivity, ΔCPR) and insulin resistance (homeostasis model assessment of insulin resistance, HOMA-IR) were assessed before and 1 month after pancreatectomy using the oral glucose tolerance test (OGTT) and glucagon stimulation test. We assessed long-term hemoglobin A1c (HbA1c) levels in patients, with a follow-up time of 3 years.

Results
Percentages of patients diagnosed with abnormal OGTT decreased after PD (from 12 [30%] to 7 [17.5%] of 40 patients, p = 0.096); however, they increased after DP (from 4 [13.8%] to 8 [27.6%] of 29 patients, p = 0.103), although the changes were not statistically significant. ΔCPR decreased after both PD (from 3.2 to 1.0 ng/mL, p < 0.001) and DP (from 3.3 to 1.8 ng/mL, p < 0.001). HOMA-IR decreased after PD (from 1.10 to 0.68, p < 0.001), but did not change after DP (1.10 and 1.07, p = 0.42). Median HbA1c level was higher after DP than after PD for up to 3 years, but the differences were not statistically significant.

Conclusions
In comparisons of pre- and 1 month post-pancreatectomy data, glucose tolerance showed improvement after PD, whereas it worsened after DP. Insulin secretion decreased after both PD and DP. Insulin resistance improved after PD, but did not change after DP. Further studies are warranted to clarify mechanisms of improved insulin resistance after PD.

Heterogeneous Effects of Agricultural Technical Assistance in Colombia
Authors: Torres Franco Nicolás Arturo , Dávalos Eleonora , Morales Leonardo Fabio 
Published: September 2021

AbstractSmall family farms account for 72% of the farms in the world. Most of these farms, in developing countries, face labor productivity gaps. One of the strategies to increase agricultural productivity focuses on implementing technical assistance programs. Using agriculture microdata, we estimate the marginal treatment effect of receiving technical assistance services. We find that technical assistance generates heterogeneous effects. On average, agricultural units receiving technical assistance increased their agricultural production by 50.4%. However, there is important heterogeneity of technical assistance’s effects across the production units’ unobserved and observed characteristics.
Potential of surrogate modelling in compressor casing design focussing on rapid tip clearance assessments
Authors: Schmidt T. , Gümmer V. , Konle M. 
Published: September 2021

ABSTRACTLosses induced by tip clearance limit decisive improvements in the system efficiency and aerodynamic operational stability of aero-engine axial compressors. The tendency towards even lower blade heights to compensate for higher fluid densities aggravates their influence. Generally, it is emphasised that the tip clearance should be minimised but remain large enough to prevent collisions between the blade tip and the casing throughout the entire mission. The present work concentrates on the development of a preliminary aero-engine axial compressor casing design methodology involving meta-modelling techniques. Previous research work at the Institute for Turbomachinery and Flight Propulsion resulted in a Two-Dimensional (2D) axisymmetric finite element model for a generic multi-stage high-pressure axial compressor casing. Subsequent sensitivity studies led to the identification of significant parameters that are important for fine-tuning the tip clearance via specific flange design. This work is devoted to an exploration of the potential of surrogate modelling in preliminary compressor casing design with respect to rapid tip clearance assessments and its corresponding precision in comparison with finite element results. Reputed as data-driven mathematical approximation models and conceived for inexpensive numerical simulation result reproduction, surrogate models show even greater capacity when linked with extensive design space exploration and optimisation algorithms.Compared with high-fidelity finite element simulations, the reductions obtained in computational time when using surrogate models amount to 99.9%. Validated via statistical methods and dependent on the size of the training database, the precision of surrogate models can reach down to the range of manufacturing tolerances. Subsequent inclusion of such surrogate models in a parametric optimisation process for tip clearance minimisation rapidly returned adaptions of the geometric design variables.

The Xlendi Bay shipwreck (Gozo, Malta): a petrographic and typological study of an archaic ceramic cargo
Authors: Anastasi Maxine , Capelli Claudio , Gambin Timmy , Sourisseau Jean-Christophe 
Published: September 2021

AbstractAn underwater survey off the southwest coast of the island of Gozo revealed a well-preserved shipwreck 110 m below the surface. The site belonged to a previously unknown wreck with a cargo of volcanic millstones and ceramic amphorae dating to the 7th century BC. This article presents the first results of thin-section analysis taken from the pottery objects, and concludes that the ship was carrying a heterogeneous cargo of amphora-borne goods from the Maltese islands, North Tunisia, and possibly Sicily, making it the earliest, known shipwreck in the central Mediterranean; and provides the earliest evidence for Maltese external trade in the central Mediterranean.
Study of metabolomics in selenium deprived Przewalski’s Gazelle (Procapra przewalskii)
Authors: Wu Ting , He Jian , Shen Xiaoyun 
Published: September 2021

AbstractTo understand why Procapra przewalskii does not show the same white myopathy as sheep in Se-deficient regions and to provide reference for feeding nutrition level of artificial population and selection of wild reintroduction areas in the later period, a Se-deficient model was established. The mineral elements content, physiological and biochemical parameters in blood and serum metabonomics were determined. In the Se-deficient group compared with the control group, the Se content was highly significantly lower (P < 0·01), and the Cu content was significantly higher (P < 0·05). The activity of glutathione peroxidase was significantly lower (P < 0·05), but total superoxide dismutase was significantly higher (P < 0·05). By matching the mass spectrum data of compounds with the Kyoto Encyclopedia of Genes and Genomes (KEGG database), eighty-six types of differential metabolites in the serum were identified. The main metabolic pathways included secondary bile acid biosynthesis, biosynthesis of unsaturated fatty acids and pyrimidine metabolism. Further analysis showed that there were seven different metabolites in pyrimidine metabolism pathway between the two groups. And there was no significant difference in erythrocyte, Hb and total antioxidant capacity between the two groups (P > 0·05). The above results showed that the differential metabolism of substances exhibited complementary functions, thus alleviating some adverse effects and resulting normal activities of P. przewalskii can be carried out under the condition of dietary Se content lower than 0·05 mg/kg.
HIV testing and ethnicity among adolescent girls and young women aged 15–24 years in Ghana: what really matters?

AbstractDespite the high prevalence of HIV among adolescent girls and young women (AGYW) aged 15–24 years in Ghana, HIV testing remains low among this population. The objective of this study was to examine the relationship between ethnicity and HIV testing among AGYW in Ghana. The 2014 Ghana Demographic and Health Survey data were used and analyses were restricted to 3325 female participants aged 15–24 years. Chi-squared tests and a logistic regression model were used to assess the association between ethnicity and HIV testing. Furthermore, the PEN-3 cultural model informed the conceptual framework that explained the relationship between ethnicity and HIV testing behaviour. Results from the bivariate analysis showed an association between ethnicity and HIV testing among AGYW (p<0.05). However, when controlling for other behavioural and socioeconomic determinants of HIV testing in the logistic regression, there was no association between ethnicity and HIV testing. The significant predictors of HIV testing were marital status, having multiple sexual partners, and condom use. The AGYW who were married (adjusted odds ratio [aOR] = 4.56, CI: 3.46–6.08) or previously married (aOR = 4.30, CI: 2.00–9.23) were more likely to test for HIV compared with those who were never married. Having multiple sexual partners (aOR = 0.41, CI: 0.20–0.85) and condom use (aOR = 0.56, CI: 0.38–0.84) were associated with lower odds of HIV testing. The results provide evidence that ethnicity is not associated with HIV testing among AGYW in Ghana, as the bivariate association was attenuated when other behavioural and socioeconomic determinants of HIV testing were accounted for. These findings highlight the importance of considering individual-level factors, community-level factors, and other socio-cultural factors as they really matter in the development of HIV prevention programmes for adolescent girls and young women in Ghana.
ALGORITHM TO CONSTRUCT INTEGRO SPLINES
Authors: MIJIDDORJ R. , ZHANLAV T. 
Published: September 2021

AbstractWe study some properties of integro splines. Using these properties, we design an algorithm to construct splines$S_{m+1}(x)$of neighbouring degrees to the given spline$S_m(x)$with degreem. A local integro-sextic spline is constructed with the proposed algorithm. The local integro splines work efficiently, that is, they have low computational complexity, and they are effective for use in real time. The construction of nonlocal integro splines usually leads to solving a system of linear equations with band matrices, which yields high computational costs.
Health system challenges affecting falls prevention in persons living with HIV: perspectives from physiotherapists in four sub-Saharan regions
Authors: Charumbira Maria Y. , Berner Karina , Louw Quinette A. 
Published: September 2021

AbstractAim:The aim of this study was to explore the perspectives of physiotherapists in four selected regions of sub-Saharan Africa regarding health system challenges impacting the integration of physiotherapy-led falls prevention services in the primary care of persons living with HIV (PLWH).Background:Falls may pose a significant problem among younger PLWH in low- and middle-income countries. Physiotherapists’ role in optimising function and quality of life can do much in the prevention of falls in PLWH and reducing the harm that results. However, falls prevention strategies have not been implemented effectively especially in primary health care settings in sub-Saharan Africa. Physiotherapists’ account of the health system challenges they encounter may provide insights into potential strategies that may be considered in optimising fall prevention for PLWH in poorly resourced settings.Methods:A descriptive qualitative study was conducted in selected urban districts in the capital cities of four sub-Saharan African countries. In-depth interviews were conducted with 21 purposively selected physiotherapists involved in the primary care of PLWH. Audio recordings of interviews were transcribed verbatim and analysed using deductive thematic content analysis.Findings:The main results are presented in the theme ‘Health care system challenges’ and in nine categories informed by the WHO health system framework: lack of policies and clinical practice guidelines, shortage/Inaccessible falls prevention services, inadequate human resource, physiotherapists not adequately equipped in falls prevention, inaccessible/No facilities for BMD measurement, inefficient data capturing systems, lack of evidence regarding falls among PLWH, unclear physiotherapy role descriptions, inefficient referral system. Physiotherapists highlighted the need for more information and research regarding fall prevention for PLWH, promote their role in the primary care of PLWH and adopt a patient-centred approach to fall prevention.
Revisiting the legitimacy question of the Nigerian 1999 Constitution
Authors: Arowosegbe Jacob O. 
Published: September 2021

AbstractThis article revisits the legitimacy question as it touches the Nigerian 1999 Constitution, bringing to the discourse a review and application of pertinent theoretical perspectives on constitution making and constitutional legitimacy. This theoretical and pragmatic approach introduces a refreshing angle to the debate, revealing the paucity of any attempt to ascribe any legitimacy claim to a constitution with a doubtful normative claim and fraudulent attribution of its source and legitimacy to the people. The author finds the consent basis of constitutional legitimacy as most attractive to a divided state like Nigeria, and concludes by advocating the adoption of a blend of the principles of the constituent assembly and post sovereign constitution-making models for the production of a new people-driven and inclusive constitution to meet the needs of the Nigerian people.
