Published: March 2021

Abstract
Optical emission spectroscopy (OES) measurements are performed on the third positive system (3PS) and Ångstrom system bands for microwave discharge CO2 plasma with its discharge pressure of 1 Torr. The molecular vibrational temperature T
v and rotational temperature T
r of CO b 3Σ+ and CO B 1Σ+ states, which are the CO electronically excited upper states of the 3PS band and of the Ångstrom band, respectively, are determined as the best fitting parameters in the theoretical calculation of the optical emission spectra for both emission bands. The general theoretical fitting procedures showed that T
v ≃ 0.15–0.24 eV and T
r ≃ 0.08–0.15 eV for the CO b 3Σ+ state based on the OES analysis of the 3PS band. Meanwhile, the general fitting of the CO Ångstrom band is difficult with a mono-rotational temperature, whereas two rotational temperatures with bulk component

for the CO B 1Σ+ state in the microwave discharge CO2 plasma. The observed nonequilibrium characteristics are discussed in terms of molecular processes in the CO2 plasma not only for the differences between CO b 3Σ+ and CO B 1Σ+ states, but also for the two-temperature characteristics in the CO B 1Σ+ state.

Masking interferes with haptic texture perception from sequential exploratory movements
Authors: Drewing Knut , Lezkan Alexandra 
Published: March 2021

AbstractHaptic texture perception is based on sensory information sequentially gathered during several lateral movements (“strokes”). In this process, sensory information of earlier strokes must be preserved in a memory system. We investigated whether this system may be a haptic sensory memory. In the first experiment, participants performed three strokes across each of two textures in a frequency discrimination task. Between the strokes over the first texture, participants explored an intermediate area, which presented either a mask (high-energy tactile pattern) or minimal stimulation (low-energy smooth surface). Perceptual precision was significantly lower with the mask compared with a three-strokes control condition without an intermediate area, approaching performance in a one-stroke-control condition. In contrast, precision in the minimal stimulation condition was significantly better than in the one-stroke control condition and similar to the three-strokes control condition. In a second experiment, we varied the number of strokes across the first stimulus (one, three, five, or seven strokes) and either presented no masking or repeated masking after each stroke. Again, masking between the strokes decreased perceptual precision relative to the control conditions without masking. Precision effects of masking over different numbers of strokes were fit by a proven model on haptic serial integration (Lezkan & Drewing, Attention, Perception, & Psychophysics 80(1): 177–192, 2018b) that modeled masking by repeated disturbances in the ongoing integration. Taken together, results suggest that masking impedes the processes of haptic information preservation and integration. We conclude that a haptic sensory memory, which is comparable to iconic memory in vision, is used for integrating sequentially gathered sensory information.
Functional results after operative treatment of talus fractures
Authors: Gavrilovski Andreja , Gavrilovska-Dimovska Aleksandra , Aleksovski Goran 
Published: March 2021

Fractures of the talus do not occur frequently, accounting for about 0.1% of all fractures. Failure to achieve anatomic reduction, exponentially increases the risk of postoperative aseptic osteonecrosis and posttraumatic osteoarthritis. The purpose of this study was to evaluate and compare the short-term and medium-term functional outcomes in patients who underwent open reduction and internal fixation of talus fractures. Materials and methods: At the University Clinic for Traumatology in the period between 2017 to 2020, 14 patients with talus fractures were surgically treated. The inclusion and exclusion factors were determined, all patients signed the consent and the study passed the ethics committee. Results: All patients underwent open reduction and internal fixation with screws or reconstructive plate. Follow-up was done on the 14th postoperative day, 1st month, 3rd month and 6th month. At the 6th month follow-up, the functional outcome was tested using the Kitaoka score unified by the American Orthopedic Foot and Ankle Society. This injury is too rare for conclusions to be brought out of and to be compared to larger studies. However, all major studies from reference trauma centers lead to the same conclusions, that the treatment of these fractures is complex Anatomical reduction is mandatory for a better outcome. Conclusion: A protocol for the treatment of posttraumatic osteoarthritis should be introduced, given the high rate of its occurrence despite the satisfactory surgical technique.
Prospecter un site où enfouir des déchets nucléaires
Authors: Patinaux Leny 
Published: March 2021

Cet article porte sur le travail des géologues de l’Agence nationale pour la gestion des déchets nucléaires (Andra). Il montre que les prospections qu’ils réalisent sont destinées à caractériser la géologie d’un site de stockage autant qu’à familiariser une région avec la présence de l’industrie nucléaire. Ce texte insiste sur les liens qui relient les profondeurs géologiques à la surface : les forages et les recherches effectuées mais aussi les circulations hydrogéologiques susceptibles d’entraîner les radionucléides enfouis vers la surface. De plus, ce texte montre comment le creusement du laboratoire souterrain de Bure (Meuse) affecte la roche et transforme les représentations de celle-ci qu’en ont les géologues de l’Andra. Ainsi, cet article analyse les rapports politiques et épistémiques des géologues de l’Andra aux formations géologiques où pourraient être enfouis des déchets nucléaires.
Histoire des « sols vivants »
Authors: Pessis Céline 
Published: March 2021

Cet article se propose de considérer plusieurs séquences historiques de mise à l’agenda de la catégorie savante de « sol vivant » en France dans les mondes agricoles et agronomiques des années 1930 aux années 1970. L’enquête porte sur la construction de la catégorie en elle-même, son statut ontologique variable, sa place fluctuante au sein des savoirs agronomiques établis, et sur la composition historiquement changeante de ces « sols vivants ». Elle décrit les différents acteurs, les arènes principales et secondaires ainsi que les projets sociotechniques qui firent exister les sols comme vivants durant une période d’intense modernisation agricole. Elle fait ainsi ressurgir des voix critiques, des cultures épistémiques minorisées et des agendas alternatifs de recherche et de progrès agricole.
Le sol de la ville-territoire
Authors: Viganò Paola , Barcelloni Corte Martina , Vialle Antoine 
Published: March 2021

Les exigences politiques actuelles en matière d’aménagement du territoire appellent à la convergence de plusieurs regards interdisciplinaires sur un nouvel objet : les sols fortement transformés par l’homme, dont une part significative est située dans le milieu urbain spécifique de la ville-territoire. Dans ce contexte, la présente contribution se propose de réinterroger la notion de « projet de sol » proposée par l’urbaniste Bernardo Secchi, en explorant les relations que le projet urbain peut entretenir à la production de connaissances sur les sols et sur la relation sol-ville. L’urbanisme, par les biais des hypothèses théoriques et opérationnelles à partir desquelles il restructure et transforme l’espace, autant que par les questions qui émergent de la modification spatiale elle-même, entretient avec le sol une relation qui relève simultanément de la production de nouvelles lectures et représentations et de l’activité de projection. Grâce à une série de « stratégies cognitives » élaborées dans le cadre de plusieurs cas d’étude à différentes échelles, notre équipe a pu ouvrir plusieurs pistes de réflexion sur le nécessaire renouvellement du « projet de sol » en réponse aux enjeux socio-environnementaux de la ville-territoire contemporaine.
Pulmonary rehabilitation for cystic fibrosis: A narrative review of current literature
Authors: Kalamara Evgenia I. , Ballas Evangelos T. , Pitsiou Georgia , Petrova Guergana 
Published: March 2021

Pulmonary rehabilitation is a key component in cystic fibrosis care. This review summarizes the recent evidence in the area of pulmonary rehabilitation for cystic fibrosis in the form of questions and answers regarding interventions, indications, benefits and risks of pulmonary rehabilitation. Pulmonary rehabilitation includes airway clearance techniques, exercise training, education and behaviour change and can improve patients’ exercise capacity, muscle strength, quality of life and nutritional status. Airway clearance techniques have beneficial effects for clearing mucous. Over the past years, evidence for the beneficial effects of exercise training on exercise capacity and overall lung health is growing. In cystic fibrosis, multiple factors result in reduced exercise capacity. All modalities of pulmonary rehabilitation should be offered to patients with cystic fibrosis, as the benefits in most cases outweigh the risks, though the optimal regimens need to be yet defined.

Les investigations ont été faites sur les fleurs de Cajanus cajan en vue d’estimer l’impact de l’activité de Dactylurina staudingeri sur la pollinisation, la production en gousses et en graines à Dang, en 2016 et 2017. Pour chacune de ces années, 540 boutons floraux ont été étiquetés sur 120 plantes réparties en quatre traitements: 120 fleurs laissées en libre pollinisation, 120 fleurs protégées des insectes, 200 fleurs protégées, puis découvertes, visitées exclusivement par D. staudingeri et de nouveau protégées et 100 fleurs protégées, découvertes et à nouveau protégées, sans visite d’insectes ou de tout autre organisme. Le taux de fructification, le nombre moyen de graines par gousse et le pourcentage de graines normales ont été comparés entre ces traitements. Sur 33 espèces d’insectes recensées, D. staudingeri était majoritaire avec 12,19% de 6037 visites. Cette abeille prélevait fortement le nectar et récoltait faiblement le pollen au niveau des fleurs de C. cajan. La vitesse moyenne de butinage était de 7,14 fleurs/min. Via l’efficacité pollinisatrice d’une visite florale, D. staudingeri a augmenté le taux de fructification de 14,71%, le nombre moyen de graines par gousse de 35,29% et le pourcentage de graines normales de 17,31%. La conservation des colonies de D. staudingeri à proximité des exploitations de C. cajan est recommandée pour assurer la hausse des rendements de cette culture et favoriser une bonne pratique de la méliponiculture dans la région.Abstract Investigations were made on the flowers of Cajanus cajan in order to estimate the impact of the activity of Dactylurina staudingeri on pollination and yields at Dang, in 2016 and 2017. For each of these years, 540 flowers buds labeled on 120 plants were divided into four treatments: 120 open-pollinated flowers, 120 bagged flowers, 200 flowers protected, then unbagged, exclusively visited once by D. staudingeri and rebagged, and 100 flowers bagged, unbagged and rebagged without insect or any other organism visit. The fruiting rate, the mean number of seeds per pod and the percentage of normal seeds were compared between these treatments. Among 33 insect species recorded, D. staudingeri was prominent with 12.19% of 6037 visits. This bee harvested intensely nectar and collected slightly pollen from C. cajan flowers. The mean foraging speed was 7.14 flowers/min. Through the pollinating efficiency of a single flower visit, D. staudingeri increased the fruiting rate by 14.71%, the mean number of seeds per pod by 35.29% and the percentage of normal seeds by 17.31%. The conservation of D. staudingeri colonies close to C. cajan farms is recommended to improve yields of the crop and to promote the good meliponiculture in the region.

This research work was aimed at investigating the effects of vitamin C, E and garlic interaction on tramadol induced toxicity in Wistar rats. Thirty five (35) rats were used for the study and rats were shared into five study groups namely; the positive control group fed with water and rats pellets, the negative control group was induced with tramdol only, the TmVC group in which 0.2mg of tramadol was induced and 0.2ml of vitamin C were administered, The TmVE group in which 0.2 mg of tramadol was induced and vitamin E was administered. The TmG group in which 0.2mg of tramadol was induced and garlic was administered. The body weight, organ weights and serum enzyme activities of the rats were monitored during the experimental period. The enzyme activity level of ALT remained constant in the positive control and negative control groups but began to rise in the TmVC group in which vitamin C was administered and kept rising in the TmVE group and the most significant increase came in the TmG group in which garlic was administered. AST was lower in all of the groups in which tramadol was administered compared to the positive control (group one) with the highest drop in the TmG group in which garlic was administered. ALP, however, showed significant decrease in all the groups except TmG when compared to the positive control at (P<0.05). High density lipoprotein was relatively low in negative control when compared to positive control at (P<0.05). High density lipoprotein was high in antioxidants treated groups compared to negative control at (P<0.05). The low density lipoprotein was high in negative control when compared to positive control. The antioxidant treated groups showed no significant decrease in low density lipoproteins when compared to negative control group.

Objectives: Dexamethasone has beneficial effects on postoperative nausea and vomiting, however, many clinicians have raised legitimate concerns regarding its effect on blood glucose concentrations. This study determined the safety and efficacy of a single pre-operative dose of dexamethasone for PONV prophylaxis in patients undergoing breast surgery.
Design: Prospective, double-blind, placebo-controlled trial
Setting: Surgical wards of the Korle-Bu Teaching Hospital, Accra, Ghana
Participants: The study was conducted among breast surgery patients. They were consecutively recruited and randomized into two groups: dexamethasone (n = 47) and placebo (n = 47).
Interventions: Patients in the dexamethasone group received 8mg (2mls of 4mg/ml) dexamethasone while those in the placebo group received 2mls of saline intravenously. PONV impact scores and blood glucose levels were recorded at 4, 8 and 24 hours postoperatively.
Main outcome measures: Incidence of PONV and blood glucose levels
Results: The incidence of postoperative nausea (PON) was lower in the dexamethasone group compared with the placebo group (12.8% vs. 29.8%; p-value= 0.044). There was no significant difference in the incidence of postoperative vomiting (POV) and PONV between the two groups. Blood glucose levels were higher in the dexamethasone group throughout the study period and significant at 8 and 24 hours postoperatively (p < 0.05). There was no difference in the incidence of clinically significant hyperglycemia between the groups (p-value = 0.169).
Conclusion: A preoperative intravenous dexamethasone 8mg, reduces PON but not POV or PONV in breast surgery without clinically significant postoperative hyperglycemia.

Published: March 2021

Objectives: To assess health professionals’ perception and determinants of their health and practice of preventive self-care
Methods: An analytic cross-sectional design was employed, and 232 professionals were selected by stratified sampling from all health professional departments of Delta State University Teaching Hospital. Healthcare professionals who had worked in the hospital for at least six months were included in the sampling frame. Pregnant women and supernumerary professionals were excluded. A self-administered questionnaire was used, and data analysed using SPSS. The main outcome measures were the level of perception of self-health and level of practice of preventive selfcare.
Results: More than four-fifths of doctors and 64.8% of nurses had good perception of their health, with significant association between perception and service area (X2 = 11.828, p =0.008). Screening practice was lowest amongst doctors except for HIV/HBV screening. Whereas 63.4% of all participants adjudged their BMI to be normal, only 36.2% actually had normal BMI, the difference being significant (p <0.001). Almost 20% of doctors had not had a BP check in a year or more, and the same proportion of doctors and nurses had never checked their FBS. The proportion of personnel who had never checked their serum lipid profile was high among nurses (76.1%) and doctors (58.3%).
Conclusion: Respondents had good perception but poor preventive behaviour, beginning management after disease onset. This may be ominous for the sector. Urgent health promotion action to safeguard productivity is needed. Comprehensive data from a multi-centre study will provide a deeper understanding of the issue.
