Exports, Imported Inputs, Two-way Trade, and Productivity: The Role of Absorptive Capacity

ABSTRACT This article estimates the effects of imported inputs, exporting, and two-way trade on productivity. This includes exploring the role of absorptive capacity in the underlying relationships using panel data from manufacturing firms in Ghana. The results show that the ability of firms that both export and import to enhance productivity contemporaneously in the short term depends critically on absorptive capacity as captured by the proportion of skilled workers. The ability of two-way traders to learn from prior exporting experience and assimilate R&D spillovers from prior use of imported inputs to enhance productivity in the short term depends on absorptive capacity.

Hygroscopic behavior of spray dried acerola and seriguela mixed juice powder stored

Spray drying is an alternative to extend the shelf life of fruits. However, fruit juice powders present problems during their storage because they are hygroscopic. The objectives of this study were to determine adsorption isotherms of mixed juice powder of acerola and seriguela at different temperatures, to identify the best-fit isotherms models and to assess their physicochemical properties. Following physics properties were assessed: apparent and absolute density, solubility, porosity, flowability, cohesiveness, morphology, mean particle size, surface analysis and pore distribution, thermal properties and antioxidant activity. Static-indirect method was used to determine the adsorption isotherms. Experimental data of the water activity and equilibrium moisture were fitted to five mathematical models. The models best fitted to the adsorption curves were the GuggenheimAnderson-de Boer (GAB), Linearized Brunauer–Emmett–Teller (BET) and Oswin models, P < 10%. The value of the solubility was 79.45%, the absolute density was 1.03 g cm, the porosity was 84.47%, and the apparent density was 0.16 g cm. The mixed juice powder showed an irregular surface morphology and shape. The results indicated that the mixed juice powder has high thermal stability and can be used as a source of antioxidant with market potential by the food industry.
Seasonal and Agricultural Response of Acidobacteria Present in Two Fynbos Rhizosphere Soils

The Acidobacteria is one of the most abundant phyla in most soil types. Fynbos plants are endemic to South Africa, and these soils provide the ideal habitat for Acidobacteria, because of its low pH and oligotrophic properties. However, little is known about their distribution in the fynbos biome and the impact of cultivation of plants on Acidobacterial diversity. Therefore, the aim of this study was to determine the effect of seasonal changes and cultivation on the relative abundance and diversity of Acidobacteria associated with Aspalathus linearis (rooibos) and Cyclopia spp. (honeybush). This study was based on rhizosphere soil. A total of 32 and 31 operational taxonomic units (OTUs) were identified for honeybush and rooibos, respectively. The majority of these were classified as representatives of subdivisions 1, 2, 3, and 10. Significant differences in community compositions were observed between seasons for both honeybush and rooibos, as well as between the cultivated and uncultivated honeybush. Acidobacteria had a significantly positive correlation with pH, C, Ca2+, and P. In this study, we have shown the effect of seasonal changes, in summer and winter, and cultivation farming on the relative abundance and diversity of Acidobacteria present in the soil of rooibos and honeybush.
Geriatric Nutritional Risk Index Is Associated With Prognosis in Patients With Pulmonary Arterial Hypertension and Chronic Thromboembolic Pulmonary Hypertension

Background: The Geriatric Nutritional Risk Index (GNRI) is a simple tool for assessing nutritional risk that predicts prognosis in patients with heart failure. This study evaluated associations between the GNRI at first hospitalization and prognosis in patients with pulmonary artery hypertension (PAH) and those with chronic thromboembolic pulmonary hypertension (CTEPH). Methods and Results: This retrospective investigation included 104 patients with either PAH or CTEPH who were treated at Kagoshima University Hospital in Japan. Patients were divided into a high (≥92) and low (<92) GNRI groups. Body mass index and serum albumin levels were significantly lower in the low GNRI group (P<0.001). Over a median follow-up period of 24 months, the incidence of pulmonary hypertension rehospitalization was higher in the low GNRI group (P=0.04). Kaplan-Meier analysis revealed that the cumulative event-free rate was significantly lower in the low GNRI group (P=0.002). Low GNRI was significantly associated with a poorer outcome after adjusting for different sets of confounding factors, including: age and sex (P=0.004); age, sex, and PAH (P=0.043); and age, sex, and mean pulmonary artery pressure (P=0.003). Conclusions: The GNRI at first hospitalization is useful for predicting prognosis in PAH and CTEPH patients.
Asymmetric effect of exchange rate volatility on trade in sub-Saharan African countries

PurposeThe purpose of this study is to examine the effect of asymmetric structure inherent in exchange rate volatility on trade in sub-Saharan African countries from 2005 to 2017.Design/methodology/approach17 countries in sub-Saharan African Countries are used for the study. Exchange rate volatility is generated using generalised autoregressive conditional heteroscedacity (1,1), while the asymmetric components of exchange rate volatility are generated using a refined approach of cumulative partial sum developed by Granger and Yoon (2002). Two-step generalised method of moments is used as the estimation technique in order to address the problem of endogeneity, commonly found in panel data.FindingsThe result from the study shows the evidence of exchange rate volatility clustering which is strictly persistent in sub-Saharan African countries. The asymmetric components (positive and negative shocks) of exchange rate volatility have negative and significant effect on trade in the region. Meanwhile, the effect of negative exchange rate volatility is higher on trade when compared with the positive exchange rate volatility. Furthermore, real exchange rate has negative and significant effect on trade in sub-Saharan African countries.Research limitations/implicationsThe outcomes of this study are important for participants in foreign exchange market. As investors in foreign exchange market react more to the negative news than positive news, investors need to diversify their risk. Also, regulators in the market need to formulate appropriate macroeconomic policies that will stabilize exchange rate in the region.Originality/valueThis study deviates from extant studies in the literature by incorporating asymmetric structure into the exchange rate trade nexus using a refined approach.
Tropical chemodiversity in selected angiosperm families

Die dieser Arbeit zugrundeliegende Hypothese ist der erwartete Zusammenhang zwischen phytochemischer Stoffausstattung und taxonomischer Verwandtschaft auf Familien- oder Gattungsebene. Das phytochemische Profil von einer Klasse von Sekundarmetaboliten umfasst sehr oft nur einige strukturell sehr ahnliche Derivate und ist zumeist charakteristisch fur ein Taxon. Um diese Hypothese zu verifizieren wurden die Alkaloidprofile von Arten aus der palaotropisch verbreiteten Familie der Stemonaceae aus der Gruppe der Monokotyledonen sowie einige neotropische Arten der Rubiaceae aus der Gruppe der Dikotyledonen untersucht. Die Pflanzenfamilie der Stemonaceae ist durch das Auftreten von speziellen Alkaloiden, den Stemona Alkaloiden, gekennzeichnet. Diese Stoffklasse umfasst Substanzen mit entweder einer Pyrrolo[1,2-α]- oder einer Pyrido[1,2-α]-azepin Struktur. Innerhalb der Gattung Stemona zeigen diese Alkaloide ein auffallendes Verbreitungsmuster, das sich auch in der Phylogenie widerspiegelt. Innerhalb der Gattung Stichoneuron stellt die Art Stichoneuron calcicola durch das Anreichern von Pandanamin einen Sonderfall dar, da die beiden anderen bisher untersuchten Arten Stichoneuron caudatum und S. halabalensis Alkaloide vom Stichoneurin-Typ akkumulieren. Das Pandanamin ist aus Pandanus amaryllifolius bekannt und das Auftreten in den Stemonaceae weist auf enge verwandtschaftliche Beziehungen zu der Familie der Pandanaceae hin. Die Untersuchungen an verschiedenen neotropischen sowie palaotropischen Arten aus der Psychotria Verwandtschaft (Rubiaceae) zeigten einerseits die Tendenz Tryptamin-Iridoid Alkaloide, auch bekannt als Monterpen-Indol Alkaloide (MIA), und andrerseits Iridoide anzureichern. Die untersuchten Arten aus der Gattung Ronabea, R. emetica und R. latifolia, akkumulieren Iridoide als typische Sekundarstoffe. Im Gegensatz dazu weisen die anderen untersuchten Arten aus dieser Pflanzenfamilie Tryptamin-Iridoid Alkaloide als typische Sekundarstoffe auf. Innerhalb dieser Stoffklasse tritt jedoch eine Differenzierung im Verhaltnis Tryptamin- zu Iridoidanteil von 1:1 bis 1:2 auf. Die erhaltenen Resultate zeigen, dass einige der isolierten Sekundarstoffe als chemische Marker geeignet sind und die Resultate von phylogenetischen Studien weitgehend unterstutzen.
Hydrocarbures aromatiques polycycliques et leurs dérivés nitrés et oxygénés dans l'air ambiant : caractérisation physico-chimique et origine

Plusieurs etudes sur la toxicite des particules dans l'air ambiant montrent que la phase polaire, qui contient entre autres des Hydrocarbures Aromatiques Polycycliques oxygenes et nitres (OHAP et NHAP), est plus toxique que la fraction aromatique contenant les HAP classiques. Dans ce contexte, l'objectif de ce travail etait de caracteriser chimiquement les NHAP et OHAP dans l'air ambiant de differents milieux (trafic, urbain, peri-urbain, rural et altitude). Les prelevements ont ete realises dans le cadre du programme de recherche POllution des Vallees Alpines (POVA) au cours de l'hiver 2002-2003 et de l'ete 2003 et dans la region de Marseille l'ete 2004. Les deux phases, gazeuse et particulaire, ont ete etudiees et une caracterisation des particules par tranche granulometrique a egalement ete effectuee. Les resultats obtenus sur les OHAP et les NHAP ont permis d'alimenter la base de donnees tres limitee sur ce type de composes et ce pour des atmospheres variees. Le developpement d'une methode d'analyse simultanee par GC/NICI-MS des NHAP et OHAP sur des matrices complexes, facile a mettre en œuvre et utilisable en routine, nous a permis de montrer que les niveaux de concentrations des OHAP dans l'air ambiant sont du meme ordre de grandeur que ceux des HAP alors que les concentrations des NHAP sont de 1 a 2 ordres de grandeur inferieures. L'estimation du risque cancerigene a partir de facteurs d'equivalence toxique montre que le risque attribue aux NHAP peut atteindre 20% du risque total. L'etude de rapports specifiques de NHAP a montre que sur les sites proches des sources de pollution, les NHAP ont une origine primaire forte alors que leur formation par reaction en phase gazeuse est evidente en ete sur les sites ruraux eloignes des sources directes de pollution et qu'elle a lieu principalement de jour, initiee par OH. Il apparait que les emissions des vehicules essence sont une source non negligeable de NHAP et de OHAP dans l'atmosphere. Le OHAP 9,10-anthraquinone presente une double origine (primaire diesel et formee par photochimie) sans pour autant pouvoir distinguer le lieu de la formation (sur le support du prelevement ou dans l'atmosphere). La partition entre les deux phases des HAP, OHAP et NHAP, est extremement dependante de la masse moleculaire du compose considere et de la temperature. L'etude de cette partition semble pouvoir apporter des informations quant a l'origine primaire ou secondaire des derives des HAP. Enfin, les HAP, OHAP et NHAP sont essentiellement (>80%) associes a la fraction fine de l'aerosol (Dp<1,3 µm) et ce quelque soit la saison consideree (hiver et ete). Les caracteristiques chimiques des differentes classes de composes (polarite…) peuvent neanmoins jouer un role quant a leur distribution en taille.
Bat flies (Diptera: Streblidae) associated with phyllostomid bats (Chiroptera: Phyllostomidae) in caves in Mexico

ABSTRACT The Family Streblidae is represented by 246 species distributed worldwide. In order to contribute to the knowledge of streblid richness in Mexico, we recorded the associations between Streblidae and the New World leaf-nosed bats (Phyllostomidae) collected in different caves in Mexico. For each streblid species their geographical and host spectrum is reported, and diagnostic characters are illustrated. Twenty-nine caves from six Mexican states were sampled. A total of 86 bats were collected belonging to eight genera and 11 species and from these a total of 297 streblid specimens of 14 species and five genera were collected. This study updates the knowledge of streblid diversity in Mexican cave habitats providing high resolution images of external anatomy.
Les sous-unités spécifiques de l'ARN polymérase I

Rpa34 et Rpa49 sont deux sous-unites non-catalytiques de l'ARN polymerase I (Pol I) conservees de la levure a l'homme. Rpa34 s'associe au domaine N-terminal (entre les positions 63 et 119) de Rpa49. Cette fixation stabiliserait Rpa49. La deletion du domaine Nterminal de Rpa49 (rpa49-119,416) abolit l'association de Rpa34 avec l'ARN polymerase I. La mutation rpa34Δ ne provoque pas de defauts de croissance. Cependant Rpa34 devient indispensable avec top1Δ et avec rpa135-L656P ou rpa135-D398N deux mutants qui sont sensibles au mycophenolate. Neanmoins, ces defauts sont supprimes par la surexpression de Rpa49, renforcant ainsi l'idee que Rpa34 s'associe a Rpa49. Rpa49 est critique pour la fixation et la dissociation de Rrn3 lors des etapes d'initiation et d'elongation. rpa49Δ (ou la deletion du domaine conserve C-terminal dans le mutant rpa49 ::HIS3) diminue le recrutement de Rrn3 sur le promoteur. Cependant, cet effet est supprime par la deletion du domaine N-terminal de Rpa43. Les mutants rpa49 sont egalement incapables de liberer completement Rrn3 durant la transition entre l'initiation et l'elongation de la transcription. Le dimere Rpa49/Rpa34 facilite donc le recrutement de l'ARN polymerase I et la conversion de l'ARN polymerase I dans une forme competente pour elongation.
Assessment of Nursing Care Skills in Neonatal Unit: A Cross Sectional Observational Study

Objective: Increased hospital treatment is required to reduce neonatal mortality in low/middle-income (LMIC) countries. Nurses are vital for providing safe and efficient treatment, but a shortage of nurses and high patient workloads can lead to missed treatment. We aimed to evaluate thecare provided to newborns and finding missing care using direct observation methods. Material and Methods: Cross sectional observational study. The sample size was 133 which were calculated through Slovin’s formula. An adopted research tool was used which contain two sections. Section I included demographic data of nurses and neonates admitted in the ward. Section IIwas an Observational checklist on neonate’s care with “Yes” “NO” which include 5 main themes that had sub points. Result: Handing over the baby was less fifty five percent. Member not assesses the patient at the end of shift 54.1% nurses done this and 45.1% missed this task. Intravenous drug administration with a septic technique was 42 percent. Counselling of kangaroo mother care was 45.9 percent done and 54 percent missed. Conclusion: Research addresses a significant gap in global literature regarding quantification of nurse’s treatment using direct observational methods. We found considerable variability in the implementation of the task with potentially significant consequences for well-being and health of patients. The concentration of nursing tasks in babies was less than 60% on average. Tertiary care setting environment lacks a large proportion of nursing care with potentially serious effects on patient health and outcomes.

Association of Total Dietary Fats and Its Subtypes with Risk of Breast Cancer

Specific classes of dietary fatty acids may be important modifiers of breast cancer (B-Ca) risk. Aim of this study was identification risk of subtypes of dietary fat for B-Ca. This case–control study carried out in Rizgary Teaching Hospital in Erbil city. Data collected by interview questionnaire and included demographic and reproductive properties; anthropometric measurements; and medical history. Dietary data collected by food frequency questionnaire. They were analyzed by program for Mosby’s Nutritrac Nutrition Analysis Software, for calculation intake of dietary; fiber, total fat, and its subtypes, energy intake, acceptable macronutrient distribution range, and antioxidant nutrients. Statistical analysis was performed using SPSS program. Polyunsaturated fats decreased risk of B-Ca while saturated and monounsaturated fats (Cis form) increased risk among all and postmenopause obese women, respectively. Risk of cancer increased significantly in high percentage of energy intake from monounsaturated fats, cooking oil, and dietary red meats. The study concluded that total polyunsaturated fatty acids (PUFA) decrease risk of B-Ca among obese menopause woman. Increase risk of B-Ca by cooking oils and animal origin diet may due to increased intake of saturated monounsaturated and specific PUFA. These subtypes of dietary fats may promote hormones imbalance and inflammation.
The Effect of COVID-19 CORONA VIRUS on Sustainable Teaching and Learning in Architecture Engineering

On 11 March, the World Health Organization (WHO) announced that the COVID-19 outbreak became a global pandemic. The governments have been implementing measures to limit the number of people congregating in public places. Therefore, the Ministry of Education stated that all educational institutes should complete the 2019-2020-2 semester using online video conferences and virtual classes. The aim of this research is to study the effect of COVID-19 on teaching and learning during the last three months of lockdown after shifting to virtual classes. The research study the procedures applied by the College of Architecture Engineering in Dar Al Uloom University. The Adding value is improving the E-Learning process for the upcoming semesters and solving the negative points for a better education. To achieve this objective the researcher, distribute a survey to the students to scale their experience and record the positive points, and to find a solution to the negative points to solve these problems. The outcome of the research showed a good experience and many recommendations to be applied in the coming future.
Touchless classes and absent bodies: teaching physical education in times of Covid-19

ABSTRACT Bodies have been claimed to be an ‘absent presence’ and touch ‘risky business’ in physical education (PE). We have now witnessed how these claims are intensified in pandemic times of Covid-19, particularly in countries that have adopted extreme lockdown measures. This paper explores how PE practices have become ‘touchless’ and bodies absent using the theoretical concepts of risk and assemblage. The paper focusses on a group of pre-service PE teachers who were keen on undertaking their PE practicum experience and who were forced to switch to online mode. Data were collected through participant-produced drawings and comments on the drawings. Results suggest that the pre-service teachers are experiencing a mix of emotions during this time, miss the physical contact with students and believe the subject of PE is losing its identity as a consequence of the current situation. The conclusions of this study reveal a shift in the way that bodies are being constituted as assemblages now, and the possibility that pre-service teachers are missing out on an important aspect of their practicum experiences because of the lack of direct contact with students. We also wonder if pre-service teacher education programmes should put more emphasis on better preparing the students to teach online, and what will be the long-term consequences in the teaching of PE because of the current Covid-19 pandemic situation.
