Published: May 2022

Background: The spread of coronavirus (Covid-19) had many psychological consequences. Nurses experience anxiety due to their professional duties. Considering the importance of mental health and caring behaviors in nurses, the present study was conducted to investigate Covid-19 anxiety in nurses and its relationship with cognitive flexibility. Method: The present study was conducted on 100 nurses of a selected hospital in 2021. Data collection tools included demographic questionnaire, Corona Disease Anxiety Scale (CDAS) and Cognitive Flexibility Inventory (CFI). Data analysis was performed through version 22 of SPSS software using Mann-Whitney, Kruskal–Wallis, independent sample t-test, one-way ANOVA and correlation tests. Results: The mean of cognitive flexibility was 96.68 (13.72). The median of Covid-19 disease anxiety was equal to 8 (9). Accordingly, the results of data analysis showed that there was no significant relationship between demographic variables and covid-19 anxiety (P>0.05). Furthermore, no significant relationship was found between cognitive flexibility and covid-19 anxiety (P>0.05). Conclusion: In this study, cognitive flexibility had no significant effect on Coronavirus disease anxiety. Considering the presentation of contradictory results in this field, authors suggest that a similar study be conducted with a larger sample size and different variables be taken into account.

Authors: Babu G. Narendra , Deepika D. Sandhya
Published: May 2022

Background: Groundnut is an important edible leguminous oilseed crop and stem rot caused by Sclerotium rolfsii is one of the major soil borne disease affecting groundnut severely in India. The current study aimed to get an understanding regarding the incidence level and pattern of prevalence of the disease in the agro-ecological condition of Andhra Pradesh. Methods: Roving survey was taken up from major groundnut growing areas in Andhra Pradesh during kharif, 2019 and kharif, 2020 in five districts. From each district predominant groundnut growing areas were chosen for assessment of the disease. Five spots of one square meter area in each field were selected randomly and Per cent disease incidence was recorded. Result: From the data it is observed that the stem and pod rot incidence was higher during kharif, 2020 when compared with kharif, 2019. The pooled data indicated that the mean stem rot incidence for the two years ranges from 5.39% to 23.56% with highest mean stem rot incidence in Krishnapuram (v), Kothapatnam (m) of Prakasam dist (23.56%) and lowest in Bandarupalli (v), Yerpedu (m) of Chittoor dist (5.39%). Among different districts highest mean stem rot incidence was recorded in Prakasam dist (18.71%) and lowest was recorded in Chittoor dist (7.11%). The stem rot severity was high in sandy soils with TAG24 variety where groundnut is being grown followed by red sandy loams and least in clay loam soils. The groundnut sole crop recorded high disease incidence when compared with intercrop of red gram. Siginificant positive correlation was recorded between stem rot, pod rot and leaf spot incidence.

Published: May 2022

Background: Forage crops in Algeria are deficient and thus constitute the primary obstacle hindering milk production. The present study aims to assess fodder practices in the wilaya of Blida, through the farms surveyed. Methods: A chronological and spatio-temporal analysis of the evolution of areas, fodder and dairy production, a survey of 76 dairy farmers and a descriptive analysis by quantiles of key variables using statistical tools (Excel and SPSS) was performed at the level of the of Blida province. A database is established using information collected from the various agricultural services of the wilaya of Blida and the examination of questionnaires from surveys carried out in the dairy farms visited. Result: The proportions by quantiles allowed discerning that two thirds of the farmers visited allocate areas of 0 to 20 hectares to fodder. With regard to a utilized agricultural area between 0 and 140 hectares, of which up to 110 hectares are allocated to cereals and the rest of the land allocated to other crops such as fruit trees. The farmers surveyed rely more on cereal crop residues to feed dairy cattle and practice little or no forage crops, which explains the delay in the development of dairy production.

Published: May 2022

Background: Currently, there is no fishery regulation for Hexaplex (Muricanthus) nigritus in northwestern Mexico. The size composition of gastropod H. nigritus was recorded from five islands of Navachiste Bay, Sinaloa (Gulf of California, Mexico). Methods: Samples were taken every two months from February to December 2018. Islands established a georeferenced GPS station: Guasayeye, La Huitussera, Tesobiate, El Metate and San Lucas, Sinaloa, Mexico. The snail H. nigritus was collected in the littoral zone of the islands during the low tide syzygy tides. The organisms were collected directly at random and the total length (TL), width (WI) and height (HI) (0.01 mm) and total fresh weight (W) and muscle foot weight (FW) (0.1 g sensitivity). In addition, the shape of the growth was estimated with the equation that describes the relationship between length and weight. Result: The island of Guasayeye was a greater abundance (48%) and the least La Huitussera (4%). The mean total length (TL) was greater in San Lucas and La Huitussera (99.5±7.2 and 95.1±15.5 mm, respectively) and lower values were recorded in Tesobiate (73.8±11.4 mm). The maximum weight recorded was 347.2 g on El Metate island. A significance in length and weight were obtained between the islands. In addition, in H. nigritus high correlations were obtained relationships, indicating positive allometric growth. For their sizes and abundance, the snail H. nigritus is a potentially interesting fishing resource for the fishers of northwestern Mexico.

Background: This study was carried out to determine the effect of addition of 1% dietary garlic and onion powder on the internal and external quality characteristics and chemical and fatty acid composition of Chukar partridges eggs. Methods: A total of 240 Chukar partridges with 60-week age was assigned to four dietary treatment group: control, 1% onion powder, 1% garlic powder and garlic onion powder, respectively. Totally, 92 eggs obtained from partridges were used for the study. Result: The addition of onion powder had significant effect on yolk weight (P less than 0.05). Supplementation of the diets with garlic and onion powder did not significantly affect quality traits of chukar eggs (P greater than 0.05). Moisture, ash and protein contents and 16 fatty acid composition of chukar eggs were not statistically affected by the addition of garlic and onion powder either. In conclusion, the addition of 1% dietary garlic and onion powder did not cause a significant change in the internal and external quality characteristics and fatty acid composition of the Chukar partridge eggs. Increasing the rate of garlic and onion powder to the chukar ration may cause some significant differences on the egg parameters.

Published: May 2022

In the context of the project "WeNet: Internet of us" we are studying the role of diversity in relation to Internet-mediated social interactions. In this paper, in particular, we analyze a possible relationship between personality aspects and social interaction mediated by digital platforms. More specifically, we rely on the five personality traits (Extraversion, Agreeableness, Conscientiousness, Emotional Stability and Openness to Experience), commonly referred to as "Big-five", and associate them to automatically extracted behavioral characteristics derived from the experience of using a Chatbot for a closed community of students at the Universidad Católica "Nuestra Señora de la Asunci´ón" (UC). The personality data comes from a self-report made by the users through questionnaires. According to a survey to the participants, overall the results show very positive appraisals about the use of the Chatbot in terms of user experience and its main functionalities, which is very encouraging for future pilots. As for the role of personality in relation to the main use of the Chatbot, although further experience is required to confirm trends, the results suggest that the Big-five personality traits are to some extent correlated with: the active participation (Agreeableness and Openess); the type of contribution in term of length of questions/requests for help and answers (Agreeableness, Neuroticism and Openness); and, the network of interactions evolution over time (Openness and Neuroticism).
Mieux nourrir la planète : diversifier les cultures pour construire des systèmes alimentaires durables
Authors: Malézieux Eric , Beillouin Damien , Makowski David
Published: May 2022

Aujourd’hui, d’importantes mutations de l’agriculture mondiale sont nécessaires pour produire suffisamment d’aliments sains pour tous, tout en préservant la qualité des terres, de l’air et de l’eau et en sauvegardant la biodiversité. Mais produire suffisamment et préserver en même temps l’environnement est une équation particulièrement complexe à résoudre. Les pratiques agroécologiques, dont un principe essentiel est l’usage de la biodiversité cultivée, constituent une voie prometteuse pour assurer ces mutations. De nombreuses preuves qualitatives et quantitatives montrent leur efficacité sur les plans agricole et environnemental et confirment leur capacité à répondre aux impératifs de production mondiale sur le long terme. Parmi les voies possibles de diversification, l’agroforesterie, les cultures associées et la rotation des cultures permettent d’augmenter significativement la production et favorisent la biodiversité et les services écosystémiques fournis — qualité du sol, contrôle des maladies et ravageurs, qualité et usage de l’eau. Ces preuves permettent de fonder de nouvelles politiques publiques à mettre en œuvre des échelles locales à l’échelle mondiale. La réalisation de telles politiques est cruciale dans les régions vulnérables au changement climatique et dont les besoins alimentaires sont en augmentation, comme l’Afrique subsaharienne.

This qualitative research was aimed to investigate the needs of the program, its usefulness, perceptions, and scope of topics that should be covered in online teaching preparation program. As result of this research, the skills and characteristics of effective online teachers were identified and discussed as well as details on mandatory topics that should be included in the training for online teaching in higher education institutions. The information on how to better prepare new online instructors was also presented. The research findings were applied to the existing DSU online teaching program or "Online Learning Academy" to enhance the preparation for online instructors, and they can also be applied and utilized to similar professional development at other institutions.
Construcciones causativas en amahuaca (Pano)
Authors: Angulo Pando Candy Milagros
Published: May 2022

En este artículo, se ofrece una discusión sobre las propiedades morfosintácticas y semánticas de las construcciones causativas en amahuaca, lengua pano de la Amazonía peruana, desde una perspectiva tipológico-funcional. Esta lengua presenta el morfema causativo general -ma, causativos supletivos totales o léxicos y el transitivizador -n, que también se encuentran en las lenguas de la familia. Por el contrario, el amahuaca presenta estrategias innovadoras: causativos semisupletivos segmentales y suprasegmentales. Se propone que estas formas han sido el resultado de procesos morfofonológicos propios de la lengua, que han cambiado la forma de los causativos mencionados, pero no su significado, debido a que estas estrategias están relacionadas con los causativos morfológicos que se encuentran en otras lenguas de la familia. Este artículo proporciona una descripción de cada una de las estrategias mencionadas, así como la explicación del tipo de causación (directa o indirecta) que conceptualizan. Así, se señala cómo los mecanismos causativos se distribuyen en el dominio funcional de la causación siguiendo la propuesta de Shibatani (2002) y Shibatani & Pardeshi (2002).

Published: May 2022

Penetrating neck injuries are a surgical challenge. In particular, penetrating neck injuries associated with carotid artery injuries have a high mortality rate. Overt external hemorrhage is unanimously considered as an indication for surgical exploration. The authors present a case of successful surgical management for a penetrating common carotid artery injury using a Pruitt-F3 Carotid Shunt (LeMaitre Vascular Inc., Burlington, MA, USA) in a 60-year-old male patient who was transferred to the level 1 trauma center due to a metal fragment piercing his neck while working. Active pulsatile bleeding was observed from the 3-cm-long external wound on the anterior neck in zone II. Emergent neck exploration showed near-total transection of the left common carotid artery just below the carotid bifurcation. After a Pruitt-F3 Carotid Shunt was applied to the injured carotid artery as a temporary vascular shunt, artificial graft interposition was performed for the injured common carotid artery. The patient experienced cerebral infarction as a complication caused by ischemia-reperfusion of the common carotid artery but was discharged in a suitable state for rehabilitation therapy.

Masyarakat lokal kalimantan secara umum memiliki keragaman budaya yang sangat unik. Faktual di lapangan menjelaskan bahwa kepercayaan masyarakat lokal menyimpan unsur-unsur budaya dalam wadah kearifan lokal masyarakat dayak yang banyak kita jumpai dalam bentuk linguistik maupun nonverbal yang dipadukan serta disinergikan secara kreatif untuk menjaga dan memelihara lingkungan dengan tujuan manusia dan alam mencapai keserasian dan keselarasan. Ritual tiwah memiliki makna tersendiri jika dikaji dengan konteks pendekatan geografi, karena kajian ilmu geografi sendiri tak terbatas hanya pada kajian fisik saja, akan tetapi aktivitas masyarakat, perkembangan budaya maupun hal-hal subtansial yang terkait pada pergerakan dan persebaran baik itu dalam konteks abstraksi maupun faktual yang menjadi unsur utama dalam kajian ilmu geografi. Korelasi budaya tewah dengan pendekatan ekologi merupakan suatu perspektif mengenai metodologi dalam mempelajari perkembangan kepribadian yang mempertimbangkan aspek-aspek di luar individu, yaitu dari sisi lingkungan di mana individu berada.

Academic contrapower sexual harassment in public universities in Zimbabwe
Authors: Mawere D. , Seroto J.
Published: May 2022

Sexual harassment in the workplace, including the university, is not a behaviour perceived to be perpetrated only by males. In this article contrapower sexual harassment was investigated to find out whether female students harassed male lecturers at universities, and how harassment manifests with a view to devising measures to mitigate such harassment incidences. A qualitative case study research design was employed to explore the thoughts and experiences of participants at two public universities in Zimbabwe. Purposive sampling was employed in the identification and selection of participants with knowledge and experience of subjecting male lecturers to contrapower sexual harassment. Data were gathered through audio-taped face to face in-depth interviews with female undergraduates using a digital voice recorder. As data were collected through interviews, an iterative process was done. The study verified the existence of contrapower sexual harassment of male lecturers by female students. The study found that the measures that can be taken to mitigate contrapower harassment should include the explicit identification of all behaviours that constitute harassment and their consequences in university codes of conduct and policies. Universities should build a culture of respect in which students and lecturers interact without fear of harassment from either party. Universities need to ensure that lecturers are informed of the available resources should they have disturbing experiences pertaining to harassment from a student.
“Fresh meat”: First year female students negotiating sexual violence on campus residences
Authors: Anderson B. , Naidu C.
Published: May 2022

Abstract This article focuses on first-year black female students at the University of KwaZulu-Natal who were exposed to and experienced sexual violence. The aim of the study was, broadly, to determine how female students experience and negotiate gender, sexuality and violence in campus residences. Semi-structured individual interviews were utilised to generate data. The findings show that violence was shaped by gender and power dynamics. These students were first years, and predominantly from poor backgrounds, and therefore particularly vulnerable to sexual violence and unequal relationships. Alcohol, substance abuse and dangerous masculinised spaces further exacerbated their vulnerability. Poverty, scarce resources and gender intersect to produce vulnerability and constrained forms of their agency that translate into transactional relationships. The findings also suggest that being first year female students have implications for how these young women negotiated their newfound freedom away from the parental gaze. The study highlights the ways in which these first-year students are aware that sexual violence is prevalent on campus particularly in certain spaces such as Dark City and residence rooms. Members of the SRC and DSRA are cited as likely perpetrators of sexually predatory behaviours. We therefore propose that the Gender Based Violence Policy at UKZN should be introduced to first year students by way of induction courses, and that these courses should also include gender and sexuality education to help ensure that awareness around gender violence permeates the lives of all students.

For decades since the central dogma, cancer biology research has been focusing on the involvement of genes encoding proteins. It has been not until more recent times that a new molecular class has been discovered, named non-coding RNA (ncRNA), which has been shown to play crucial roles in shaping the activity of cells. An extraordinary number of studies into shown that ncRNAs represent an extensive and prevalent group of RNAs, including both oncogenic or tumor suppressive molecules. Henceforth, various clinical trials involving ncRNAs as extra ordinary biomarkers or therapies have started to emerge. In this review, we will focus on the prognostic and diagnostic role of ncRNAs for breast cancer.

In this paper, we present a method to map information regarding service activity provision residing in governmental portals across European Commission. In order to perform this, we used as a basis the enriched Greek e-GIF ontology, modeling concepts, and relations in one of the two data portals (i.e., Points of Single Contacts) examined, since relevant information on the second was not provided. Mapping consisted in transforming information appearing in governmental portals in RDF format (i.e., as Linked data), in order to be easily exchangeable. Mapping proved a tedious task, since description on how information is modeled in the second Point of Single Contact is not provided and must be extracted in a manual manner.

Recent studies have shown that distributive fluvial systems are the dominant fluvial forms in modern continental sedimentary basins, thus composing a large part of the stratigraphic record. This study provides a basin-scale architectural analysis of the Guará Formation, from the Upper Jurassic record of southwestern Gondwana, and attempts to compare the formation's depositional model to those developed for distributive fluvial system (DFS) successions. This time interval is significant because it was a period of intense tectonic activity related to the Paraná–Etendeka plume and the Gondwana breakup. Quantitative analyses were performed on stratigraphic sections at 17 locations (exposing a total of 720 m of stratigraphy) located in southern Brazil and northern Uruguay, from a larger dataset of 64 locations (comprising a total of 1070 m of stratigraphy). Four facies associations were identified: perennial fluvial channel fills, ephemeral fluvial channel fills, floodplain deposits, and aeolian deposits, indicating a dryland climate. Spatial trends were analyzed along a downstream-oriented transect (NNE–SSW) across the system. Grain size, channel-body thickness, number of stories, and bar thickness decrease downstream, indicating a reduction in channel depth, flow capacity, and channelization of the fluvial system, interpreted to be associated with downstream-increasing bifurcation, infiltration, and evapotranspiration. Based on spatial trends and distribution of facies associations, the deposits are interpreted to have been accumulated from a large DFS which can be divided into four zones, from proximal to distal: Zone 1, dominated by perennial fluvial channels; Zone 2, a mixture of perennial and ephemeral channels; Zones 3 and 4, deposits situated externally of the fluvial channel belts dominated by aeolian and floodplain deposits prevailing in each zone, respectively. The Guará Formation likely records the stratigraphic signature of the largest distributive fluvial systems reconstructed from both modern and ancient datasets, and one of the first where fluvio–aeolian interaction is quantified. The Guará Formation DFS model presented herein is key to understanding paleoenvironmental, paleoclimatic, and geotectonic changes related to Gondwanan fragmentation.

This article summarizes initial efforts on the evaluation of the joint action of chemical inhibition and magnetic field to maximize the potential of scale mitigation in downhole conditions. This strategy is seen as a promising way to enhance flow assurance reliability in high cost deepwater wells where workover jobs are very expensive. This strategy is being considered as a good option for downhole applications where portions of the wellbore are not assisted by chemical injection or even as a redundancy which can attenuate effects of chemical injection failure. The calcium carbonate scale in the oilfield is typically controlled by chemical inhibitors, in several types and concentrations, depending on the saturation index related to the application. A magnetic field has the potential of retarding scaling of inorganic salts in oil production/water treatment systems. A preliminary assessment of the association of magnetic field and inhibitors to postpone carbonate scaling has been evaluated, based on tube blocking test method and two saturation indexes levels (2.8 and 3.03 – SSP Norm Scale). The reactor, with nominal diameter of 1/8", was operated under the total flow rate of 52 mL/min. (Re ≈ 800), the pressure of 50 kgf/cm2, temperatures of 40, 60, and 80 °C, using hydroxymethyl amino-di(methylene phosphonic acid) inhibitor type at different concentrations. The magnetic field employed was 1,6 Tesla. Results indicate that at given conditions, expressive delay can be achieved with the combination of the two techniques, while in other situations the system may need redesign. This study reveals an interesting potential of coupling two different mitigation strategies aiming different applications, such as spacing the necessity of squeeze treatments and optimizing surface treatment.
Calcium Carbonate Scale Management Over Life of Field - A Case Study

Published: May 2022

The paper focuses on a field case of an offshore oil well producing from the Norwegian Brage Brent reservoir. The gas lifted well has a tendency for calcium carbonate scaling in the upper completion. Shortly after start of production, the well experienced a sudden significant increase in scale deposition. This required additional operational efforts for remediation using acid. The investigation into the reasons for the sudden increase in scaling, as well as remediation options employed for its mitigation, are presented within the paper. Both subsurface scale simulation evaluations and operational procedures undertaken to remediate the wellbore scaling are detailed.

Scale inhibitors have been widely used for scale control in oil and gas production. The accurate measurement of residual scale inhibitor concentration in the produced brine is essential for scale prevention. However, these scale inhibitors are effective at sub-stoichiometric concentration in most production conditions (e.g., 1 mg/L active concentration, or even lower). It is rather difficult to measure such low inhibitor concentration with traditional ICP-OES/MS or IC method, especially for non- or low- phosphorous polymeric scale inhibitors. Furthermore, the combo of scale inhibitors and corrosion inhibitors are used in the most application, which requires the measurement of effective scale inhibitor concentration. Therefore, there is a high demand of a fast, sensitive, universal and cheap method to determine the effective scale inhibitor concentration in complicated field brines. In this study, a new assay method is developed to determine the effective scale inhibitor concentration. This assay method is based upon the linear relationship between the effective inhibitor concentration and the critical time of barite scale formation, which is determined by turbidity measurement using a CSTR apparatus in Brine Chemistry Inhibitor (BCIn) method. This linear relationship has been validated by experimental observation. The recommended procedures for the sample preparations from the real oilfield brine were also developed to help in the quick setup of the measurement. Various types of inhibitors (i.e., SPCA, PPCA, PVS) have been tested with different sample types (i.e., in the synthetic brines, laboratory samples and real oilfield produced brine). The new assay method is quick, robust and accurate with the relative error less than 10% even at 1 mg/L of inhibitor, which indicating a limit of detection (LODs) around 0.1 mg/L for most cases.
Non-Uniqueness of Adsorption Isotherm History Matching in Squeeze Treatments

After squeezing the well with scale inhibitor, field samples are normally collected from the produced brine to monitor the squeeze treatment lifetime, resulting in a return concentration profile. This profile is typically used to derive a field-representative isotherm by history matching the return concentration data. This field isotherm is then used to predict the lifetime and to optimize the subsequent treatments in the well. However, isotherm history matching is an inverse problem, and its solution might be non-unique. Hence, multiple isotherms may be identified that satisfy the data-match criteria reasonably well, causing prediction uncertainty for the next squeeze treatments. Ignoring this feature and selecting just one single isotherm out of a whole range of the plausible solutions may result in a poor-quality lifetime prediction based on the model. The main objective in this work is to evaluate the non-uniqueness of the isotherm history matching and to illustrate its effect on designing the subsequent treatments.

Four synthetic cases were considered, and the SI concentration return profile was produced for each case to demonstrate the non-uniqueness nature of the problem. Moreover, to represent the field conditions more closely, randomly generated synthetic noise was also added to the profiles. In practice, the noise may come from the errors in sampling/analyzing or from the reservoir heterogeneity. A real field case was also considered with the field data available for two subsequent squeeze treatments. A sensitivity study was conducted to show the degree of uncertainty in the lifetime prediction for a variety range of squeeze designs, using several isotherms matching the return profile. The systematic method proposed in this manuscript assists in the isotherm history matching, leading to a more accurate squeeze lifetime prediction.
