Authors: Rodrigues Rosa Isabel 
Published: October 2021

Abstract
Background
In the last two decades, the transformations that have affected the business world have had a great impact on professional performance standards. As such, they have contributed significantly to increasing concerns regarding employability. Particularly, these concerns are even more worrying among students who are looking for their first job. Consequently, this leads organizations to question whether the skills these candidates have are sufficient and adequate for them to enter the job market. Although it is a problem that deserves an urgent response, it is still poorly understood amongst academics, which is why it continues to be essential to define and signal which skills candidates should develop in order to guarantee a better person-function fit. Hereupon, the present study aims at the construction and validation of a short skills inventory for students who are looking for their first job. This inventory will allow alignment between candidates' skills and the level of performance expected by their future employers.

Methods
The development of the short skills inventory for students looking for their first job was based on Classical test theory and Item response theory methodologies. Specifically, its developmental process encompassed three studies. Study 1, comprising a qualitative scope, dealt with the development and construction of the items (n = 97). Study 2, of an exploratory nature, was intended to evaluate the psychometric properties of the instrument (n = 173). Finally, Study 3, of a confirmatory nature, was aimed at validating the results gathered from the Exploratory factor analysis (n = 407).

Results
This inventory is a valuable asset for the selection of students who are looking for their first job. The analyzes carried out over the various studies show that this instrument has satisfactory psychometric properties, and, as such, is a valid and reliable instrument and an alternative to the instruments currently used in the recruitment and selection processes.

Conclusions
The construction of this short skills inventory brings theoretical and practical benefits. In short, it contributes to reducing Portugal’s gap regarding psychological assessment upon selection considering the lack of validated and verified instruments for students looking for their first job.
Atmospheric oxygenation of the early earth and earth-like planets driven by competition between land and seafloor weathering

Published: October 2021

AbstractOxygen is a potential biosignature for terrestrial Earth-like planets. The primary source of oxygen on Earth is oxygenic photosynthesis, which may be limited by the supply of riverine phosphorus. Therefore, phosphorus supply from the chemical weathering of continents is crucial for the evolution of pO2. Chemical weathering occurs on both the continents and seafloor and stabilizes the climate, but phosphorus is only supplied by continental weathering. The amount of continental weathering relative to seafloor weathering may be critical for primary productivity and pO2. The area of continents could change as a result of continental growth and the amount of ocean mass on the planetary surface, and these factors could be very different on extrasolar Earth-like planets. Here, we investigated the effects of continental and seafloor weathering on the atmospheric oxygen levels, in terms of the Earth-like phosphorus-limited marine biosphere. We used a simple biogeochemical model and investigated a possible relationship between continental growth and atmospheric oxygen levels. We found that the atmosphere could evolve totally different redox conditions (an abrupt rise of atmospheric oxygen levels or a reducing condition to form organic haze) caused by continental growth, which changes the relative contribution of silicate weathering feedback from seafloor to continent. We also found that conditions with lower solar luminosity and a larger land fraction provided a preferable condition for the phosphorus-limited marine biosphere to produce high levels of oxygen in the atmosphere. We also found that the atmospheric oxygen level is strongly affected by the activity of the anaerobic marine microbial ecosystem. Our results suggest that the area of land on the planetary surface may be crucial for achieving high oxygen levels in a phosphorus-limited marine biosphere. These results contribute to the fundamental understanding of the general behaviors of Earth-like planets with oceans and an Earth-like marine biosphere.

AbstractHypervelocity impacts are among the fundamental phenomena occurring during the evolution of the solar system and are characterized by instantaneous ultrahigh pressure and temperature. Varied physicochemical changes have occurred in the building blocks of celestial bodies under such extreme conditions. The constituent material has transformed into a denser form, a high-pressure polymorph. The high-pressure polymorph is also thought to be the constituent of the deep Earth’s interior. Hence, experiments using a high-pressure and temperature generating apparatus have been conducted to clarify its crystal structure, pressure–temperature stability range, and transformation mechanisms. A natural high-pressure polymorph (mineral) is found from terrestrial and extraterrestrial rocks that experienced a hypervelocity impact. Mineralogists and planetary scientists have investigated high-pressure minerals in meteorites and rocks near terrestrial craters over a half-century. Here, we report brief reviews about the experiments producing high-pressure polymorphs and then summarize the research histories of high-pressure minerals occurring in shocked meteorites and rocks near terrestrial craters. Finally, some implications of high-pressure minerals found in impact-induced shocked rocks are also mentioned.Graphic abstract

Abstract
Background
The evaluation of the DNA damage generated in cumulus cells after mature cumulus-oocyte complexes vitrification can be considered as an indicator of oocyte quality since these cells play important roles in oocyte developmental competence. Therefore, the aim of this study was to determine if matured cumulus-oocyte complexes exposure to cryoprotectants (CPAs) or vitrification affects oocytes and cumulus cells viability, but also if DNA damage is generated in cumulus cells, affecting fertilization and embryo development.

Results
The DNA damage in cumulus cells was measured using the alkaline comet assay and expressed as Comet Tail Length (CTL) and Olive Tail Moment (OTM). Results demonstrate that oocyte exposure to CPAs or vitrification reduced oocyte (75.5 ± 3.69%, Toxicity; 66.7 ± 4.57%, Vitrification) and cumulus cells viability (32.7 ± 5.85%, Toxicity; 7.7 ± 2.21%, Vitrification) compared to control (95.5 ± 4.04%, oocytes; 89 ± 4.24%, cumulus cells). Also, significantly higher DNA damage expressed as OTM was generated in the cumulus cells after exposure to CPAs and vitrification (39 ± 17.41, 33.6 ± 16.69, respectively) compared to control (7.4 ± 4.22). In addition, fertilization and embryo development rates also decreased after exposure to CPAs (35.3 ± 16.65%, 22.6 ± 3.05%, respectively) and vitrification (32.3 ± 9.29%, 20 ± 1%, respectively). It was also found that fertilization and embryo development rates in granulose-intact oocytes were significantly higher compared to denuded oocytes in the control groups. However, a decline in embryo development to the blastocyst stage was observed after CPAs exposure (1.66 ± 0.57%) or vitrification (2 ± 1%) compared to control (22.3 ± 2.51%). This could be attributed to the reduction in both cell types viability, and the generation of DNA damage in the cumulus cells.

Conclusion
This study demonstrates that oocyte exposure to CPAs or vitrification reduced viability in oocytes and cumulus cells, and generated DNA damage in the cumulus cells, affecting fertilization and embryo development rates. These findings will allow to understand some of the mechanisms of oocyte damage after vitrification that compromise their developmental capacity, as well as the search for new vitrification strategies to increase fertilization and embryo development rates by preserving the integrity of the cumulus cells.

AbstractBackgroundUndernutrition among adolescents is a major public health problem in developing nations including Ethiopia. Adolescents need to have good-quantity and good-quality nutrients to cope with this rapid growth and other health risks which increase nutritional demand. This study aimed to assess the prevalence and associated factors of stunting and thinness among school adolescents in Finote Selam Town, Northwest Ethiopia.MethodsA school-based cross-sectional study among adolescent students aged 10–19 in public schools was carried out in Finote Selam Town from February 5 to March 27, 2018. A total of 397 school adolescents were included in this study. Stratified and simple random sampling techniques were employed to select study subjects. Pretested structured questionnaires were used to collect the data. Data were entered using Epi info version 7 and analyzed using SPSS version 20 and WHO AnthroPlus software. A multivariable logistic regression analysis was employed to identify factors associated with stunting and thinness. Crude and adjusted odds ratios with 95% level significance were used to measure the strength of association, and statistical significance was declared at aPvalue less than 0.05.ResultsThe prevalence of stunting and thinness among school adolescents was 21.8% and 16.9%, respectively. About 9.7% of school adolescents experienced both stunting and thinness. Being male (P = 0.031), coming from rural area (P = 0.046), having a family monthly income of less than $28.37 (P = 0.044) and having less than four dietary diversity (P = 0.021) were significantly associated with stunting. Early adolescent stage (P = 0.034), being male adolescent students (P = 0.37), having a family monthly income of less than $28.37 (P = 0.016), having a family monthly income between $28.37 and $56.74 (P = 0.021) (35.25 Birr = 1 USD) and using well water (P = 0.045) were significantly associated with thinness.ConclusionUndernutrition was a predominant problem in the study area. Sex, age, place of residence, dietary diversity, sources of drinking water and family monthly income were important factors associated with stunting and thinness among the respondents. Strategies to improve the nutritional status of adolescent students should be given much attention.

AbstractThe COVID-19 pandemic has wreaked havoc in the world from last year, and any further insults like Zika virus will surely bring the apocalypse unto us. In July 2021, Zika began spreading in India, mainly in the state of Kerala. Zika infection resembles closely COVID-19 and other arboviral infections, which might lead to delayed and misdiagnosis, further leading to underreporting of cases. Some of the feared complications of Zika include Guillain–Barré syndrome and congenital Zika syndrome leading to microcephaly. Thus, Zika virus disease (ZVD) has significant public health and social impacts. Since the trifecta of infectious diseases (host, agent and environment) are all conducive to the spread of Zika in India, there is a huge risk that ZVD might become endemic in India, which is especially dangerous in the backdrop of this pandemic. This has to be stopped at all costs: the main aspects of which are public health measures, vector control and early diagnosis, especially in case of pregnant women. The diversion of healthcare resources for this pandemic has albeit made this difficult, but we must do our bit if we have to overcome this situation.

Published: October 2021

AbstractAs of recent, microgreen vegetable production in controlled environments are being investigated for their bioactive properties. Phytochemicals like glucosinolates (GLS) are highly sensitive to varying spectral qualities of light, especially in leafy greens of Brassica where the responses are highly species-dependent. The accumulation of bioactive GLS were studied under 8 different treatments of combined amber (590 nm), blue (455 nm), and red (655 nm) light-emitting diodes (rbaLED). A semi-targeted metabolomics approach was carried out to profile common intact-GLS in microgreen extracts of Brassica by means of LC-HRMS/MS. Thirteen GLS were identified, among them were 8 aliphatic, 4 indolic and 1 aromatic GLS. Mass spectrometry data showed sinigrin had the highest average concentration and was highest in B. juncea, progoitrin was highest in B. rapa and glucobrassicin in R. sativus. The individual and total GLS in the microgreens of the present study were largely different under rbaLED; B. rapa microgreens contained the highest profile of total GLS, followed by R. sativus and B. juncea. Sinigrin was increased and gluconasturtiin was decreased under rbaLED lighting in most microgreens, glucoalyssin uniquely increased in R. sativus and decreased in B. rapa and glucobrassicin uniquely decreased in both B. rapa and B. juncea. The present study showed that rbaLED contributed to the altered profiles of GLS resulting in their significant modulation. Optimizing the light spectrum for improved GLS biosynthesis could lead to production of microgreens with targeted health-promoting properties.

Published: October 2021

Abstract
Background
Light is the critical factor that affects the eye's morphology and auxiliary plans. The ecomorphological engineering of the cornea aids the physiological activities of the cornea during connections between photoreceptor neurons and light photons. Cornea was dissected free from the orbit from three avian species as ibis (Eudocium albus), duck (Anas platyrhynchus domesticus) and hawk (Buteo Buteo) and prepared for light and scanning electron microscopy and special stain for structural comparison related to function.

Results
The three investigated avian species are composed of three identical layers; epithelium, stroma, and endothelium, and two basement membranes; bowman's and Descemet’s membrane, separating two cellular layers, except for B. buteo which only has a Descemet’s membrane. The corneal layers in the investigated species display different affinity to stain with Periodic Acid Schiff stain. The external corneal surface secured by different normal epithelial cells ran from hexagonal to regular polygonal cells. Those epithelial cells are punctured by different diameter microholes and microplicae and microvilli of various length. Blebs are scarcely distributed over their surface. The present investigation utilized histological, histochemical and SEM examination.

Conclusions
The study presents a brief image/account of certain structures of cornea for three of Avian’s species. Data distinguish the anatomic structures of the owl's eye. The discussion explains the role of some functional anatomical structures all through the vision.

AbstractThis study examines the impact of fiscal, monetary and trade policies on Nigerian economic growth from 1985 to 2020. This study adopts endogenous growth model (AK model) as its theoretical framework. The unit root test results reveal that there is mixed level of stationarity in the variables. The bound test result shows that the variables cointegrate. The ARDL long-run result shows that fiscal policies stimulate economic growth, while on the contrary, trade policies deter Nigerian economic growth. The short-run result shows that the fiscal policies has an inconsistent impact on Nigerian economic growth and thus differs from the long-run result; while government spending continues to drive economic growth in Nigeria, government revenues have no effect on the growth of the economy. The result of the impact of monetary policies shows that interest rate impels growth of the economy while money supply deters growth of Nigeria’s economy; lastly, the trade policies maintain her negative influence on the economy in both the long run and short run. Sequel to the findings, the study recommends the following: Policymakers should place more emphasis on using fiscal policy which was found to be stimulating the country's growth rate. Whenever it is expedient to use monetary policy to stimulate economic growth, policy makers should make use of interest rates as it stimulates the growth of the economy in the short run. The government should review her trade policies to reduce import by encouraging consumption of local products and motivate exporters of goods (raw material) to refine the products before exporting such.

Published: October 2021

Abstract
Background
Peptic ulcer is the term which refers to acid peptic injury of the digestive tract, and it results in mucosal break reaching the submucosa. Leaves of Capparis zeylanica are used as counterirritant, rubefacient, as a cataplasm in piles, boils and swellings. The objective of the present study was to evaluate the antiulcer activity of C. zeylanica ethanolic extract against chemically induced ulcers. The leaves were extracted with ethanol (50%) as solvent using hot perforation method. The extract was evaluated against acute and chronic ulcer models. Further, extract was evaluated for gastric autopsy of animals infected with Helicobacter pylori bacteria. The genes of rats were evaluated by gel electrophoresis method. Morphology of stomach was also studied after treatment with plant extract.

Results
Results exhibited that the area of ulcer was significantly reduced in both acute [naproxen-induced ulcer model (3.62 mm2), histamine-induced ulcer model (3.2 mm2) and ethanol-induced ulcer model (106.4 mm2)] and chronic [chronic naproxen-induced ulcer model (2.14 mm2), chronic histamine-induced ulcer model (0.16 mm2)]. The animals of naproxen-induced ulcer infected with H. pylori showed 91.48% reduction of ulcer area on 9th week after treatment with C. zeylanica extract (360 mg/kg). The rapid urease test and DNA observation revealed that no infection was present from 4th week after treatment with C. zeylanica extract (480 mg/kg). Morphological studies showed less conspicuous petechial marks and hemorrhages in stomach tissues after treatment with test drugs. Histopathological study revealed that C. zeylanica extract reduced stomach damages and eradicated H. pylori infections.

Conclusion
It can be concluded from the study that C. zeylanica possess antiulcer and anti-helicobacter activities.

Abstract
Background
Indirect calorimetry is the reference method for measuring resting energy expenditure (REE), but the necessary equipment and technical expertise are not always available. Meanwhile, the NUTrition Risk in the Critically ill (NUTRIC) scale is designed to identify patients who would benefit from nutrition therapy, but no data are available regarding the association of NUTRIC scores with REE. Several predictive formulas are available as alternatives to indirect calorimetry for calculation of energy requirements, but they have not been compared in a homogeneous group of critically ill patients. The purpose of the study is to examine the correlations between energy expenditure and NUTRIC scores or patient outcomes, and to compare measured REE with estimations of energy expenditure.

Methods
In this observational, prospective study, indirect calorimetry was performed on 50 mechanically ventilated patients. Energy expenditure was also estimated with the bodyweight-based, Faisy–Fagon, and Penn-State PSUm equations.

Results
REE was higher in patients who survived treatment than in those who died, and was positively correlated with length of stay and duration of ventilation. NUTRIC scores did not correlate with REE. The Faisy–Fagon equation overestimated expenditure, whereas PSUm was unbiased and accurate. Calculations based on 25 kcal/kg bodyweight/day overestimated expenditure, whereas 23 kcal/kg/day produced unbiased estimates with greater accuracy than PSUm.

Conclusion
REE was positively associated with patient outcomes. Energy expenditure was accurately predicted by calculations of 23 kcal/kg bodyweight/day.
