Immunogenicity and Safety of the inactivated SARS-CoV-2 vaccine (BBIBP-CoV) in patients with malignancy

Objective: Patients with malignancy suffer from a compromised immune system due to either the effects of malignancies or treatments. Cancer patients are at higher risk of different infections particularly SARS-CoV2 and usually produce weaker response to vaccines. The aim of this study was to evaluate the safety and immunogenicity of the inactivated SARS-CoV-2 vaccine (Sinopharm, BBIBP-CoV) in patients with malignancy. Material and Method: In total 364 patients with cancer (median age: 54 years old, F/M ratio: 217/147) who received two doses of Sinopharm vaccine were enrolled in this study. Vaccine related side effects was assessed by a questionnaire and the presence of SARS-CoV-2 anti-Spike protein (S) IgG and neutralizing antibody two months following vaccination were measured by immunological methods. Results: Injection site pain and fever were the most common local and systemic side effects in vaccine receivers. Two months after the first dose, anti-S IgG and neutralizing antibody were detectable in 77.1% and 80.7% of all participants, respectively with an overall response to either or both measured in 86.9% of patients The rate of seroconversion was lower in older age, those with hematological malignancies and chemotherapy receivers. Conclusion: The result of study confirmed the safety and short-term efficacy of Sinopharm inactivated vaccine (BBIBP-CorV) in patients with different type of malignancies.
The influence of snow on sea ice as assessed from simulations of CESM2

Abstract. We assess the influence of snow on sea ice in experiments using the Community Earth System Model, version 2 for a pre-industrial and a 2xCO2 climate state. In the pre-industrial climate, we find that increasing simulated snow accumulation on sea ice results in thicker sea ice and a cooler climate in both hemispheres. The sea ice mass budget response differs fundamentally between the two hemispheres. In the Arctic, increasing snow results in a decrease in both sea ice growth and sea ice melt due to the snow’s impact on conductive heat transfer and albedo, respectively. This leads to a reduced amplitude in the annual cycle of ice thickness. In the Antarctic, with increasing snow, ice growth increases due to snow-ice formation and is balanced by larger basal ice melt. In the warmer 2xCO2 climate, the Arctic sea ice sensitivity to snow depth is small and reduced relative to that of the pre-industrial climate. Whereas, in the Antarctic, the sensitivity to snow on sea ice in the 2xCO2 climate is qualitatively similar to the sensitivity in the pre-industrial climate. These results underscore the importance of accurately representing snow accumulation on sea ice in coupled earth system models, due to its impact on a number of competing processes and feedbacks.
Acoustic space partition by four syntopic Hylidae (Anura) in open habitat in Central Brazil

The use and partition of the acoustic space by anuran species are of special interest in evaluating inter-specific interactions in acoustic traits. Here we evaluate the acoustic space partitioning by four species of Hylidae at Estação Ecológica de Águas Emendadas, Distrito Federal, Central Brazil. The acoustic niche overlap among species was smaller than expected by chance, indicating low overlap in the use of the acoustic space by these species. The low overlap in call parameters found is related to their phylogenetic distances, suggesting that the acoustic space use in the Cerrado is determined mainly by historical factors than by ecological constraints in the acoustic overlap. On the other hand, the low overlap in call parameters suggests that the acoustic space in the Cerrado is shared by species of different hylid lineages.
CR-Walker: Tree-Structured Graph Reasoning and Dialog Acts for Conversational Recommendation

Growing interests have been attracted in Conversational Recommender Systems (CRS), which explore user preference through conversational interactions in order to make appropriate recommendation. However, there is still a lack of ability in existing CRS to (1) traverse multiple reasoning paths over background knowledge to introduce relevant items and attributes, and (2) arrange selected entities appropriately under current system intents to control response generation. To address these issues, we propose CR-Walker in this paper, a model that performs tree-structured reasoning on a knowledge graph, and generates informative dialog acts to guide language generation. The unique scheme of tree-structured reasoning views the traversed entity at each hop as part of dialog acts to facilitate language generation, which links how entities are selected and expressed. Automatic and human evaluations show that CR-Walker can arrive at more accurate recommendation, and generate more informative and engaging responses.
Changes In Antioxidant Enzyme Activity In Turfgrass Cultivars Under Various Saline Water Irrigation Levels To Suit Landscapes Under Arid Regions

ABSTRACT Turfgrass cover is an inevitable component in the urban landscapes of the United Arab Emirates. Tolerance to abiotic stress like salt, drought, and high temperature is a potential factor to be considered in the selection of turfgrass for the landscapes in the arid regions. Three Seashore paspalum genotypes, four Bermudagrass cultivars along with tall fescue as a control were screened for enzymatic changes under four different saline irrigation levels of 5,000, 10,000, 15,000, and 20,000 mg L−1 of salinity. Irrigation with potable water served as the control. Turfgrasses were maintained in a field experiment under factorial randomized block design for a period of two years under sustained saline conditions by working out the leaching fraction to maintain the precise level of salinity in each treatment throughout the experimental period. The activities of antioxidant enzymes such as superoxide dismutase (SOD), ascorbate peroxidase (APX), peroxidase (POD), polyphenol oxidase (PPO), and catalase (CAT) were assayed in each of the saline water treated turfgrass types. The SOD activity was found to be high in Yukon (bermudagrass) and Sea Dwarf paspalum. In the paspalum group, Salam and Sea Dwarf showed the highest SOD activity under saline condition. In Bermuda types, Yukon and SR 9554 showed the highest SOD activity compared to other bermuda types. Compared to other cultivars, Sea Isle 2000 (Paspalum type), SR 9554, and Yukon (Bermuda types) exhibited more APX activity without any significant differences among themselves. There was an elevated activity of POD initially, followed by gradual reduction upon increasing the salinity level. Salam cultivar maintained stable POD activity even at the elevated salinity levels. The paspalum types showed relatively high level of PPO activity compared to other types under salinity. Yukon cultivar showed a significantly higher activity of PPO when the salinity level was raised from 15,000 to 20,000 mg L−1. A significant increase with respect to CAT activity was exhibited in Sea Dwarf under elevated level of salinity. Saline water irrigation brought about a significant effect on the antioxidant enzyme systems to impart oxidative stress tolerance in turfgrass species.
Interbank Market and Effectiveness of Monetary Policy in Malawi

The study aimed at investigating how the interbank market affects the monetary policy transmission mechanism in Malawi. To achieve that, the study analysed the nature of the relationship between excess reserves and the interbank market rate and tried to discuss other possible factors that affect the interbank market rates in Malawi and limit the effectiveness of the central bank’s efforts that aim at influencing important interest rates in the economy. The study further analysed the strength and speed at which the interbank market rate affects other money market rates, specifically the lending rate. Using financial markets monthly data for the period 2010:1 to 2018:6, the study applied Ordinary Least Square methods for estimation using Error Correction Model. From the results of the study, it is concluded that the interbank market is the right platform through which the central bank can influence money market rates in the process of monetary policy implementation. Interbank market rates respond to levels of banking system liquidity at a speed that makes sense for monetary policy and they are able to send significant signals to other relevant market rates like lending rates. Drawing from these outcomes, the study recommends continued forecasting and controlling of banking system liquidity by the central bank and establishment of additional factors that affect the interbank market rate and hence limit the central bank’s efforts. For further improvement in the monetary policy transmission mechanism, the study recommends increased knowledge on interbank pricing models for individual commercial banks and research on the informal sector’s reaction to central bank’s policy actions.

Comparative study on the effect of Grape seed extract and sodium fluoride on demineralized Cementum of Human premolar samples

Aim: This study aimed to investigate: both effect of Grape seed extract and NaF on demineralized cementum of human premolar samples using Scanning electron microscope and Energy-Dispersive X-ray Analysis (EDX)Polarized light microscope (PLM). Materials and Methods: Thirty maxillary first premolars were assigned to three main groups (I,II,III) as the following: GI was a control group, GII was treated with grape seed extract and GIII was treated with sodium fluoride. Group I was equally divided into two subgroups, five premolars each: a negative control (received no treatment) and a positive control (after immersed in demineralizing solution). The specimens were subjected to pH cycling twice daily for two weeks, then analyzed by scanning electron with EDX and polarized
SOCIAL REPRESENTATIONS OF NURSING STUDENTS ABOUT THE COMFORT OF PATIENTS MONITORED IN INTENSIVE CARE UNITS

Objective: The objective was to analyze the social representations of nursing students and to identify in their speech elements that influence the promotion of comfort to patients monitored in intensive care. Method: This is an observational, cross-sectional, descriptive-exploratory study with a qualitative approach whose observation of the data occurred in the light of Moscovici's social representations. The chosen technique was the content analysis proposed by Bardin; the software IRAMUTEQ 0.7, alpha 2, was used to facilitate data storage. Results: Fifty-seven (57) nursing students from a private university in Rio de Janeiro who had already attended clinical or supervised curricular internship in high complexity were interviewed, according to the inclusion criteria of the research and, in its majority, components of generation Y. This study revealed that the nursing students consider the comfort of patients in the four possible contexts: physical, environmental, psycho-spiritual and social; they also think that the hard technology in question, the multi-parametric monitor, represents an important partnership in caring for critical patients. Conclusion: However, undergraduate students believe that such technology must not imply the detriment of the comfort; in their opinion, the concomitant existence of both aspects is perfectly possible. It is concluded that biomedical training focused on high technologies in the intensive care environment has given way to humanization and holistic and comforting care, and that new professionals, already accustomed to constant contact with different technologies, respect them, but they consider the care and comfort of the community as a priority.

Most significant is that they can be grown anywhere and under any weather conditions because algae have variety of species ARTICLE INFO ABSTRACT Article History: Received: Aug. 23, 2020 Accepted: Oct. 4, 2020 Online: Oct. 8, 2020 _______________
Hematological Changes in Threatened Preterm Labor (Hemoglobin & Platelets)

In Threatened PTL patients, due to inflammation and possible ongoing ischemia process, platelet activation indices like MPV and PDW should be altered than the controls.The aim of this study was to evaluate the alterations of platelet indices and hemoglobin level and to investigate whether they can be used as a predictor marker for threatened preterm birth or not.This study was a case control study included 60 pregnant women attending to the department which was divided into two groups: Study group (30 women): with threatened preterm labor and Control group (30 women): healthy pregnant wome Hemoglobin levels were measured and Platelet indices: mean platelet volume (MPV); platelet distribution width (PDW). Lower hemoglobin levels in TPL group. Also, MPV was lower in TPL group while PDW was higher in PTL group. hemoglobin level less than 9.07 g/dl may predict TPL also, MPV levels may be used for discriminating high risk population for preterm labor. By using a cut-off value 8.59 for MPV with sensitivity and specificity of 64%, 46% respectively PDW in this study revealed an area under curve (AUC) 63%. By using a cut-off value 15.98 for PDW, sensitivity was 68% and specificity was 47% for TPL. Conclusion: Preliminary findings of this study showed that hemoglobin level less than 9.07 g/dl may predict TPL also, MPV levels may be used for discriminating high risk population for preterm labor. Further prospective studies with larger sample size are needed to confirm this finding.
Drivers and Impacts of China‟s Economic Engagements in Nigeria: Focus on Infrastructures Investment

China‟s growing presence across African continent and with reference to Nigeria has variously attracted debates and mixed feeling amongst scholars and policy makers. Severally considered and described initially as ideological and political, cultural and adventurous, etc., but the phenomenal expansion of the engagement and relationship into trade and investment across economic sectors particularly infrastructure development, has many things to desire. While the public debate accentuates the imperativeness of Chinese infrastructure financing schemes and its roles in economic growth and development in Nigeria, yet vital questions on China-Nigeria economic engagement subsist. This study investigated and examined specifically the nature of the driving factors and the impacts of the economic engagement with particular interest in infrastructures investment and development. Using a non-probabilistic and qualitative research design method on secondary data sources, the study discovered that China-Nigeria economic engagement is propelled by economic, institutional, political and perception drivers with divers mixed impacts; and conclusively described the engagement as goodly-bad or sweet but bitter. This study contributes to the asymmetric view of China-Nigeria relationship by positing a balanced position from infrastructure investment perspective. The study therefore recommended that government policy makers ensure that Chinese investments alone in Nigeria‟s national infrastructures development do not and should not substitute constitutional government responsibilities, that institutional frameworks must encourage momentous indigenous private investment capital inflow into infrastructure sector, going forward, China-Nigeria engagement policies must promote purposeful, environmental, human capital, and people-centered sustainable development goals in Nigeria amongst others.
Yield and quality of strawberry fruit grown in a greenhouse in a pyramidal hydroponic system

Strawberry (Fragaria x ananassa Duchesne) is an important crop in Mexico and the world. To increase yields, various production systems have been explored, such as hydroponic systems. The objective of this study was to determine the effect of strawberry cultivars, planting densities and strata in a pyramidal hydroponic system, on plant development, production and fruit quality. The study was carried out in Salinas de Hidalgo, SLP, Mexico, in the spring-autumn cycle of 2017. The stratum factor impact on the development and yield of the crop, with the high stratum the number of leaves, crown width, increased number of fruits and yield (23.5 kg m), and quantity of soluble solids in comparison with the lower ones. The plants in the intermediate strata were less productive, probably due to the shade caused by those in the higher strata. Density and cultivar had no significant effect on fruit development, yield and quality.
Inductive and Coinductive Predicate Liftings for Effectful Programs

We formulate a framework for describing behaviour of effectful higher-order recursive programs. Examples of effects are implemented using effect operations, and include: execution cost, nondeterminism, global store and interaction with a user. The denotational semantics of a program is given by a coinductive tree in a cofree monad, which combines potential return values of the program in terms of effect operations. Using a simple test logic, we construct two sorts of predicate liftings, which lift predicates on a result type to predicates on computations that produce results of that type, each capturing a facet of program behaviour. Firstly, we study inductive predicate liftings which can be used to describe effectful notions of total correctness. Secondly, we study coinductive predicate liftings, which describe effectful notions of partial correctness. The two constructions are dual in the sense that one can be used to disprove the other. The predicate liftings are used as a basis for an endogenous logic of behavioural properties for higher-order programs. The program logic has a derivable notion of negation, arising from the duality of the two sorts of predicate liftings, and it generates a program equivalence which subsumes a notion of bisimilarity. Appropriate definitions of inductive and coinductive predicate liftings are given for a multitude of effect examples. The whole development has been fully formalized in the Agda proof assistant.
An Estimation of the Determinants of Efficiency of Rice Farmers in Benin: A Case Study of the Departments of Mono and Couffo

Rice is an important component in the quest for food security in Benin, but its production remains low and thus needs to be optimized. This study estimated technical as well as allocative efficiency and identified the sources of the inefficiency of rice farmers in Benin, with specific focus on the departments of Mono and Couffo. The study used secondary data obtained from the Ministry of Agriculture, Livestock and Fisheries. The data covers 210 rice farmers evenly spread out within the departments of Mono and Couffo. The Cobb-Douglas production frontier method was used to measure the level of technical efficiency of farmers, while allocative efficiency was examined using the marginal product value method. The results reveal that the technical efficiency of producers is at 78%, and that there are therefore possibilities of increasing rice production. The sources of inefficiency are age, sex, the level of education and access to finance. The results also revealed the existence of allocative inefficiency in rice cultivation. Manpower is overused whereas other production factors such as seeds, pesticides, and fertilizer are underutilized. Allocative efficiency is explained by sex, age, the area sown, the type of crop, and access to finance. These results indicate that rice farmers in the departments of Mono and Couffo would benefit from adopting the best agricultural practices such as the use of fertilizer, agro-chemical products, and irrigation.
Short-Selling and Information Arrival around Earnings Announcements: Evidence from Regulation SHO

Short sellers assist in impounding negative news more quickly into stock prices and improve price informativeness. However, there is a lack of consistent evidence about whether short sellers trade predominantly in anticipation of, or in response to, a public information release. To shed light on this question, we exploit Reg SHO, which reduced the constraints faced by short sellers for a subsample of U.S. firms, to examine price informativeness before, during and after earnings announcements. We show that relative to control firms, pilot firms have greater (less) price informativeness before (during) earnings announcements, suggesting that short sellers trade in anticipation of public earnings news, rather than in response to the public news.
Measurement of constant drying rate of wet material placed in a fluidized bed of inert particles under reduced pressure

ABSTRACT The objective of this study is to estimate the drying characteristics of a relatively large material immersed in a fluidized bed under reduced pressure by measuring the constant drying rate. The constant drying-rate period in a fluidized bed under reduced pressure is difficult to measure because it is extremely short. To maintain the constant drying-rate period, distilled water is directly supplied to the drying material. Through our experiment, the heat transfer coefficient of the material surface was also determined. The results were compared with data on hot air drying. The constant drying rate is higher for fluidized bed drying than for hot air drying. It suggests that the heat transfer coefficient on the surface of the drying material is much larger for fluidized bed drying than for hot air drying. For fluidized bed drying, the effect of pressure in the drying chamber on the heat transfer coefficient is slight at the same normalized mass velocity of dry air (G/Gmf). The temperature difference between the inside of the drying chamber and the drying material is much smaller for fluidized bed drying than for hot air drying. The constant drying rate increases as the pressure in the drying chamber decreases.
Growth and reproductive performance in females of Romosinuano cattle

Objective. To characterize growth curves and reproductive performance of Romosinuano cows in Mexico. Materials and methods. Weight and age records (928) of females (117) for growth traits and calving records (459) of cows (113) for reproductive traits were analyzed. Four non-linear mixed models were adjusted to describe the growth curves. Indicators of age at 50% of maturity (A50M), and percentage of maturity at 18 months of age (PM18) were estimated. The reproductive performance was evaluated through the age at first calving (AFC), the calving interval (CI), and calving rate (CR). Results. The Brody model showed the best adjustment to the growth curve. The A parameter, which estimates maturity weight, fluctuated within 430.2 and 466.2 kg; the b parameter within 0.94 and 5.45; and the k parameter within 0.001 and 0.002; depending on the used model. The A50M varied from 20 to 21 months, and the PM18 from 44.5 to 45.5%. The means for AFC, CI, and CR at 550 d were 1059±282 d, 553±68 d, and 74±19%; those indicators improved (p<0.05) when cows have a higher percentage of their maturity weight, depending on calving season. Conclusions. The estimates of maturity weight indicate that Romosinuano cattle could be considered as a breed of small or medium size, with an acceptable reproductive ability. The females with small estimated maturity size aged at first calving earlier than cows with high weights.
