Published: March 2021

Abstract
Resource-efficient wood chipping for forest-industrial processes demands large fractions of accept chips and small fractions of small-sized material, such as pin chips and fines. In Kraft pulping, a narrow distribution of wood chip thickness is important for even impregnation and for making high-quality pulp. Using newly developed forest-industrial drum-chipping technology, the investigation covered wood of varying moisture content, frozen versus unfrozen wood, and the use of different wood species. Using conventional techniques for analyzing wood chip dimensions, fast-grown spruce wood with high moisture content gave 4.2 % pin chips and fines, which was less than half of the fractions obtained with spruce wood with lower moisture content. A comparison between frozen and unfrozen pine resulted in slightly thinner and shorter chips for the frozen wood, but in both cases accept yields of up to ∼85 % were achieved. A comparison of different tree species (aspen, birch, pine, and spruce) resulted in larger accept fractions (∼90 %) for the hardwood species, even though the average length of these wood chips was as low as 17 mm. The results provide a first indication of how basic wood log properties affect the yields of accept chips and small-sized material when using modern industrial drum-chipping technology.
Determination of bulk and surface properties of liquid Bi-Sn alloys using an improved quasi-lattice theory

Published: March 2021

Abstract
The thermodynamic properties of Bi-Sn were studied at 600 and 900 K using a quasi-lattice theory. After successful fitting of Gibbs free energies of mixing and thermodynamic activities, the fitting parameters were used to investigate the enthalpy of mixing, the entropy of mixing, concentration fluctuations, Warren-Cowley short-range-order parameter, surface concentrations and surface tensions of the binary systems. Positive and symmetrically shaped enthalpies of mixing were observed in all composition range, while negative excess entropies of mixing were observed. Bi-Sn showed a slight preference for like-atoms as nearest neighbours in all composition range. The nature of atomic order in Bi-Sn at 600 and 900 K appeared similar. The highest tendency for homocoordination exists at composition where mole fraction of Bi is about 40%. It was also observed that Bi (whose surface tension is lower than that of Sn) has the highest surface enrichment in the Bi-Sn systems. Unlike many previous applications of the quasi-lattice theory where constant values were used to approximate coordination numbers, temperature and composition-dependent coordination numbers were applied in this work.

Abstract
Two series of sulfonylureas derivatives including 24 compounds (4, 7, 5a–5o, 8a–8h), among them 17 new derivatives, have been synthesized and evaluated for their α-glucosidase inhibitory activity. Compounds 5c, 5h and 8e showed significant in vitro α-glucosidase inhibition with IC50 values of 5.58, 79.85 and 213.36 µm, respectively, comparing with the standard compounds acarbose (IC50 = 268.29 µm) and glipizide (IC50 = 300.47 µm). The preliminary structure-activity relationships (SARs) of the synthesized compounds were also investigated.

Authors: Sándor Anna 
Published: March 2021

AbstractThis paper focuses on characterizing the present day situation of Slovakia Hungarian dialects and on outlining strategy for the future based on the status quo. After a brief overview of the dialect regions and their subregions, the present situation of Slovakia Hungarian dialects is described. The situation of the dialects is dependent on their linguistic features, their distance from the standard, as well as on extralinguistic (demographic, geographic, social, economic, educational, cultural, and settlements structural) factors. The present situation of the Slovakia Hungarian dialects is discussed, along with their changes, functions, and attitudes attached to them. The paper concludes that the differences are greater between the Slovakia Hungarian vs. Hungary Hungarian dialects than among the various Slovakia Hungarian dialects.

Authors: GUO Jing 
Published: March 2021

Dans cet article nous présenterons dans un premier temps les documents référentiels importants au sujet de l’évaluation de la compréhension de l’oral du chinois, puis nous ferons une synthèse analytique de ces documents pour soulever la problématique de l’absence de distinction du vocabulaire de l’écrit et de l’oral. Enfin, nous introduirons le descriptif du « _Spoken Chinese Proficiency Grading Standards and Testing Guideline_ 汉语口语水平登记标准及测试大纲». Ce dernier, avec une liste de 8 300 mots à maîtriser dans 30 domaines différents, marque d’après nous un pas significatif dans l’histoire de l’évaluation et de l’enseignement de l’oral du chinois. Cependant, en ce qui concerne la compréhension de l’oral, beaucoup reste à faire, et ceci est surtout urgent pour l’apprentissage du chinois dans un contexte non naturel.

Introduction: In order to improve the health of travellers during travel it is important to better understand the health problems faced by travellers in different destinations. The main objective of this study was to characterise the perceived health problems of travellers during and up to six months after travel on a pre-travel clinic in Lisbon, Portugal.Material and Methods: This is a prospective observational study. Participants were recruited among those travellers attending a pretravel clinic between May 2016 and April 2017, meeting the inclusion criteria (age over 18 years old and predicted time of stay from five to 90 days). Structured questionnaires were applied by telephone interviews, three and six months after arrival. Associations and their magnitude were sought between travel and traveller’s characteristics with total and specific health problems, using multiple logistic regression models.Results: Out of 364 participants who completed the study, 60% were under 37 years of age, and 87.9% presented a higher educationaldegree. Africa and Asia were travel destinations for 89.1% of travellers. Three months after travel, 39.3% confirmed some travel-acquired health problem, namely diarrhoea (26.6%) and unmeasured fever (12.4%). A malaria case was diagnosed, occurring 3.5 months after return. From a total of 189 travellers to countries with high risk of malaria and chemoprophylaxis recommendation, 65.6% adhered completely and 6.9% of those presenting fever during travel sought healthcare.Discussion: The proportion of travellers that became ill was lower compared to other published studies. Failure to follow a randomsampling method and the characteristics of the travel consultation with a particular profile of travellers in terms of level of education and ability to pay, challenges the external validity of the study.Conclusion: Health problems during or after travel occurred in 39.3% of travellers with diarrhoeal disease being the most common (26.6%). From our findings, the need for taking chemoprophylaxis for malaria or seeking health care in the presence of fever is not translated into appropriate action. The reasons are unclear and should be the subject of further research. Furthermore, research is needed with inclusion of other centres practicing travel medicine in Portugal, both in the pre-travel setting and others, in order to better understand the health risks associated with Portuguese traveller’s characteristics and destinations.

Published: March 2021

Abstract
Background: Clinical errors are one of the challenges of health care in countries; moreover, the obtaining of accurate statistics regarding clinical errors in most countries is a difficult process and varies from one study to another. The current study was conducted to identify impediments in the reporting of clinical errors in the operating theatre and the intensive care unit of a teaching hospital.Methods This study was conducted qualitatively in the operating theatre and intensive care sections of a training hospital. Data collection was conducted through semi-structured with medical care staff and senior doctors and surgical assistants. Data analysis was carried out through listening to recorded interviews and developing tape scripts of the interviews. The meaning units were identified and codified based on the type of discussion. Furthermore, codes which had a common concept were categorized in one group and by using the designated groups, the main problems were derived. Finally, the codes and designated groups were analyzed, discussed and confirmed by a panel of four experts in qualitative content, and the existing main problems were identified and categorized.Results: Barriers to reporting clinical errors were extracted in two themes: individual and organizational problems. Individual problems included 4 categories and 12 codes and organizational problems included 6 categories and 17 codes. The results showed that in the majority of cases, nurses indicated their desire to change current prevailing attitudes in the workplace while doctors expected reform policies dealing with clinical errors in teaching hospitals to be implemented at higher levels by officials. Conclusion: in order to alleviate Barriers to reporting clinical errors, individual problems and organizational problems should be resolved. To reduce individual problems, it is recommended to train the nursing and medical team in the field of error recognition. In order to solve organizational problems in the nursing team, improve the process of reporting clinical errors and in the medical team, rectifying of legal loopholes should be considered.

Abstract
Vibrio parahaemolyticus is a food-borne pathogenic microorganism that commonly exists in aquatic products. In this study, the antibacterial activities of benzyl isothiocyanate (BITC) against V. parahaemolyticus were investigated by both transcriptomic analysis and morphological verification. Treatment with 1/8 minimum inhibitory concentration (1/8 MIC) BITC resulted in 234 upregulated genes and 273 downregulated genes. We selected six virulence genes that were significantly downregulated and verified them using quantitative real-time reverse transcription-polymerase chain reaction. The verification results revealed that the relative expression levels of the six genes VP0820, VP0548, VP2233, VPA2362, fliA and fliG were only 31.0%, 31.1%, 55.8%, 57.0%, 75.3%, and 79.9% of the control group, respectively. Among them, genes VP2233, fliA and fliG are related to flagella and VP2362 can regulate a protein relevant to biofilm formation. Morphologically, we verified that the swimming diffusion diameter of V. parahaemolyticus was significantly reduced by 14.9%, and biofilm formation was significantly inhibited by treatment with 1/8 MIC BITC. These results indicated that 1/8 MIC BITC had antibacterial effect on V. parahaemolyticus by inhibiting virulence gene expression related to flagella and biofilm. These findings are helpful to further elucidate the bacteriostatic mechanism of BITC on V. parahaemolyticus and other food-borne pathogens.

Abstract
Due to the high in situ stresses, dynamic disasters occurred frequently in the Huainan mining area, China. While our understanding of the in situ stresses in this area is still insufficient. In this study, the in situ stresses of 18 sections in two boreholes in the Xinji No. 1 coalfield were measured by using hydraulic fracturing method, and the distribution of in situ stresses in the Huainan mining area were investigated. The relationship between in situ stress and geological structure in the Huainan mining area were summarized and the limitation of fault friction strength on in situ stresses were discussed. The result showed that the maximum horizontal principal stress (σH) at Xinji No. 1 mine was 13.95–25.23 MPa, the minimum horizontal principal stress (σh) was 12.16–21.17 MPa. The average azimuth of the maximum horizontal principal stress was N83.61 °E. The statistical results showed that the in situ stresses in Huainan mining area were characterized by a strike-slip faulting regime. Both the horizontal and vertical principal stresses increased approximately linearly with the increase of burial depth. The direction of the maximum principal stress in the study area is closely related to the tectonic movement and the ratio of maximum principal stress to minimum principal stress was primarily limited by the friction strength of fault. The outcomes of this research can provide some reliable engineering parameters and benefit the roadway layout and support design in the Huainan mining area.

Published: March 2021

Abstract
Background

Vitamin D3 has been identified as an immunomodulatory agent that confronts the pathogens via stimulating antimicrobial peptides (AMPs).
Objective

The effects of vitamin D3 on the expression of AMPs was assessed in experimental pasteurellosis in calves.
Methods

10 Holstein crossbred male calves (2–4 months) were chosen and randomly divided into the two groups. Pasteurella multocida was prepared (3×109 CFU/mL) and inoculated in the trachea. Vitamin D3 was injected to the treatment group after confirming the pneumonia. Blood samples were obtained from both groups at different time intervals and the peripheral blood mononuclear cells (PBMCs) were isolated. Clinical symptoms were recorded. Broncho-alveolar lavage was performed to evaluate the lung cell content. On the other hand, 10− 6, 10− 7, and 10 − 8 molar (M) of vitamin D3, was used to evaluate the expression of CD4, BMAP34, and BNBD4 genes using PBMCs under the in vitro conditions.
Results

The prescription of vitamin D3 to the treatment group caused a decline in clinical signs. Following the vitamin D3 injections the treatment groups under the in vivo conditions, significant increase was observed in the expression level of Defensin (BNBD4), and CD4. Evaluation of bronchoalveolar lavage fluid (BALF) revealed that the amount of neutrophils decreased after vitamin D injection. In vitro, increased expression of Catalicidin (BMAP34), Defensin (BNBD4), and CD4 was observed at a concentration of 10− 6 M of vitamin D3.
Conclusion

The present study indicated that vitamin D3, exerts immunomodulatory effects on many infectious diseases via activation of VDR pathways and stimulation of AMP production.
