Kinetic Simulations of Proton Mirror Instability: Phase Relations and Thermodynamics
Authors: Chang C.-K. , Hau L.-N.
Published: December 2022

Mirror-mode waves driven by the large temperature anisotropy of T
⊥/T
∣∣ > 1 have been widely observed in the solar wind, planetary magnetosheaths, heliosheath, etc. Recent studies have shown that the phase relations and thermodynamics of the mirror waves observed in the terrestrial magnetosheath may well be interpreted by the linear mixed kinetic–MHD theory of proton mirror instability. In particular, the energy laws possess the form of double-polytropic closures with the thermodynamic exponents being functions of β
⊥,∣∣ = p
⊥,∣∣/(B
2/2μ
0). In this study, we examine the time evolution of proton mirror instability based on the hybrid particle simulations for twenty sets of β
⊥,∣∣ values. Quantitative comparisons between the kinetic simulations, linear Vlasov theory, and observations are made in terms of the growth rates, phase relations, thermodynamic conditions, etc., which show high agreements. In particular, the dependences of various compressibility and thermodynamic exponents on β
⊥,∣∣ are confirmed by the kinetic simulations, which show that the polytropic exponents are in the ranges of γ
⊥ = 0.64 ± 0.21, and γ
∣∣ = 1.07 ± 0.12 consistent with the theoretical predictions and mirror observations of γ
⊥ < 1 and γ
∣∣ ≳ 1. It is shown that the observed features, including the various perturbations and wavelengths, may indeed be reproduced by the nonlinear simulations. The saturated temperature anisotropy β
⊥/β
∣∣ and plasma β
∣∣ show an anticorrelation, which may well be fitted by the modified mirror instability threshold of

This study aimed to perform a phytochemical screening and test the antibacterial, antioxidant, and anticancer activities of acetone extracts of the Coffee parasite (Loranthus ferrugineus Roxb). A phytochemical screen was performed using specific reagents. Antimicrobial testing was performed using the paper disc diffusion method. The antioxidant activity test used the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. Anticancer activity test against HeLa and A549 cells based on the 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide (MTT) assay method. Acetone extract L. ferrugineus Roxb contains alkaloids, flavonoids, triterpenoids, and tannins compounds. The acetone extract of L. ferrugineus Roxb showed activity against all the bacteria tested, with the inhibition zone diameter ranging from 6.2 mm - 11.1 mm. Acetone extract of L. Ferrugineus Roxb had a very strong antioxidant activity with a value of IC50 = 48.7122 µg/mL. The anticancer activity test showed cytotoxic activity against HeLa cells with a value of IC50 = 47.62 µg/mL and for A549 cells with a value of IC50 = 192.83 µg/mL.

Authors: Christensen Thomas H. , Singh Vivek , Stambough Jeffrey B. , Barnes C. Lowry , Schwarzkopf Ran , Mears Simon C.
Published: December 2022

The coronavirus disease 2019 (COVID-19) pandemic impacted the inpatient experience before and after total joint arthroplasty (TJA). This study aimed to examine how these changes affected patient satisfaction following TJA as recorded by Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) postdischarge surveys and comments at 2 large academic institutions. A retrospective review identified patients who completed HCAHPS surveys following primary and revision TJA at 2 academic institutions: 1 in a predominately rural southern state (Institution A) and 1 in a northeastern metropolitan city (Institution B). Patients were grouped by discharge date: pre–COVID-19 (April 1, 2019, to October 31, 2019) or COVID-19 affected (April 1, 2020, to October 31, 2020). Differences in demographics, survey responses, and comment sentiments and themes were collected and evaluated. The number of HCAHPS surveys completed increased between periods at Institution A but decreased at Institution B (Institution A, 61 vs 103; Institution B, 524 vs 296). Rates of top-box survey responses remained the same across the 2 periods. The number of comments decreased at Institution B (1977 vs 1012) but increased at Institution A (55 vs 88). During the COVID-19–affected period, there was a significant increase in the negative comment rate from Institution B (11.6% vs 14.8%,
P
=.013) and a significant decrease in the positive comment rate from Institution A (70.9% vs 44.3%,
P
<.001). There was an increase in negative patient sentiments following TJA during the COVID-19 pandemic as seen in qualitative comments but not quantitative responses. This suggests that certain aspects of the TJA patient experience were impacted by COVID-19. [

Posterior Corneal Astigmatism Does Not Influence Manifest-Treated Topography-guided LASIK Outcomes
Authors: Wallerstein Avi , Gauvin Mathieu , Bernstein Allison , Qi Susan Ruyu , Cohen Mark
Published: December 2022

Purpose:

To investigate whether the magnitude of posterior corneal astigmatism (PCA) impacts refractive and visual outcomes of primary topography-guided laser in situ keratomileusis (LASIK) and to provide guidance on treating eyes with high PCA.

Methods:

Comparative retrospective analysis of 4,541 consecutive eyes treated with Contoura (Alcon Laboratories, Inc) on the manifest refractive astigmatism. Standard outcomes of the 1,514 eyes with the lowest PCA (first tercile; low PCA group) were compared to the 1,514 eyes with the highest PCA (last tercile; high PCA group). Pearson correlation coefficient was used to assess relationships between variables.

Results:

Preoperatively, 20.9% of eyes presented with PCA of 0.50 diopters (D) or greater. The mean PCA was 0.18 ± 0.07 D in eyes with low PCA, and 0.50 ± 0.11 D in eyes with high PCA. An equivalent number of eyes achieved a cumulative postoperative unilateral uncorrected distance visual acuity of 20/20 in both the low PCA and high PCA groups (95.3% vs 94.7%;
P
= .4489). The efficacy index of both low and high PCA eyes was identical (0.99 ± 0.06 vs 0.99 ± 0.08;
P
= .3192), as was the safety index (1.00 ± 0.02 vs 1.00 ± 0.03;
P
= .0110). The magnitude of preoperative PCA was weakly correlated with postoperative refractive astigmatism (
R
= 0.1323), but not with postoperative defocus equivalent (
R
= −0.0414) or spherical equivalent (
R
= −0.0128).

Conclusions:

PCA does not negatively impact the outcomes of topography-guided LASIK targeting the manifest refraction, having identical accuracy, efficacy, and safety in eyes with both low and high PCA. There is no scientific basis to measure and consider PCA in topography-guided LASIK planning software or nomograms if the excimer laser treatment input targets the manifest refraction.

How do green bonds affect green technology innovation? Firm evidence from China
Authors: Lin Tao , Du Mingyue , Ren Siyu
Published: December 2022

As an emerging financial tool, green bonds can broaden the financing channels of enterprises and stimulate the green innovation of enterprises. Based on the A-share data of Chinese listed companies from 2012 to 2020, this paper analyzes the impact of green bonds on green technology innovation by using a method of Difference in Difference with Propensity Score Matching (PSM-DID). We found that green bonds can significantly improve enterprise green technology innovation. Its positive impact is attributed to increases in media attention and R&D capital investment and a reduction in financing constraints. Green bonds play a greater role in the green innovation of strong financial constraints enterprises, non-SOEs and large-scale enterprises. Our findings have important reference significance for the improvement of the resource allocation role of green bonds and achievement of sustainable growth.
Two-stage stochastic programming with imperfect information update: Value evaluation and information acquisition game
Authors: Wang Chang-Jun , Gao Zi-Jian
Published: December 2022

We focus on the two-stage stochastic programming (SP) with information update, and study how to evaluate and acquire information, especially when the information is imperfect. The scarce-data setting in which the probabilistic interdependent relationship within the updating process is unavailable, and thus, the classic Bayes' theorem is inapplicable. To address this issue, a robust approach is proposed to identify the worst probabilistic relationship of information update within the two-stage SP, and the robust Expected Value of Imperfect Information (EVII) is evaluated by developing a scenario-based max-min-min model with the bi-level structure. Three ways are developed to find the optimal solution for different settings. Furthermore, we study a costly information acquisition game between a two-stage SP decision-maker and an exogenous information provider. A linear compensation contract is designed to realize the global optimum. Finally, the proposed approach is applied to address a two-stage production and shipment problem to validate the effectiveness of our work. This paper enriches the interactions between uncertain optimization and information management and enables decision-makers to evaluate and manage imperfect information in a scarce-data setting.
Mathematical aspects and topological properties of two chemical networks
Authors: Khabyah Ali Al
Published: December 2022

Graphs give a mathematical model of molecules, and thery are used extensively in chemical investigation. Strategically selections of graph invariants (formerly called "topological indices" or "molecular descriptors") are used in the mathematical modeling of the physio-chemical, pharmacologic, toxicological, and other aspects of chemical compounds. This paper describes a new technique to compute topological indices of two types of chemical networks. Our research examines the mathematical characteristics of molecular descriptors, particularly those that depend on graph degrees. We derive a compact mathematical analysis and neighborhood multiplicative topological indices for product of graphs ($ \mathcal{L} $) and tetrahedral diamond lattices ($ \Omega $). In this paper, the fifth multiplicative Zagreb index, the general fifth multiplicative Zagreb index, the fifth multiplicative hyper-Zagreb index, the fifth multiplicative product connectivity index, the fifth multiplicative sum connectivity index, the fifth multiplicative geometric-arithmetic index, the fifth multiplicative harmonic index and the fifth multiplicative redefined Zagreb index are determined. The comparison study of these topological indices is also discussed.

This article presents how grammatical data are treated and presented in the first specialized lexicographic and grammatical learning e-tool for Slovenian, the Franček portal, and how these data are linked across the portal’s dictionary, advisory, and teaching components. By displaying grammatical material in an innovative manner and linking it effectively, this interactive portal—which offers reliable content and is designed following modern educational principles—is intended to contribute to motivating students to learn grammatical material. The article also draws attention to the fact that effectively linking grammatical data on the portal can play an important role in the development of language teaching and influence the methodology of language resource design.
Revision of Slovenian Normative Guide: Scientific Basis and Inclusion of the Public
Authors: Lengar Verovnik Tina , Dobrovoljc Helena
Published: December 2022

Contemporary Slovenian language standardisation includes the revision of the normative guide, a process taking place since 2013 within the Commission on Orthography. This article presents an overview of the scientific basis of this process as well as describes the systematic inclusion of different segments of the public in the phase of assessing the suitability of current orthographic rules and formulating new ones. This is due to an awareness that a normative guide can be accepted by the wider language community only through a convergence of differing opinions and codification based on arguments.
Frazeologija kot medij za izražanje stereotipnih pogledov na druge: na primeru angleških in slovenskih frazemov z etnonimi
Authors: Vrbinc Alenka , Vrbinc Marjeta
Published: December 2022

V članku obravnavamo nacionalne stereotipe, ki jih najdemo v angleških in slovenskih izlastnoimenskih frazemih z etnonimi ali njihovimi izpeljankami. Naš namen je pojasniti razloge, zakaj so se v angleščini oz. slovenščini v določenem časovnem obdobju pojavili stereotipni pogledi na druge narode. Na podlagi konkretnih primerov frazemov razlagamo njihovo (pretežno negativno) konotacijo. Ugotavljamo, da so angleški frazemi z etnonimi posledica zgodovinskih odnosov Angležev z drugimi (večinoma) evropskimi narodi, ki so jih imeli Angleži za sovražnike ali tekmece, slovenski frazemi z etnonimi pa so lahko rezultat prevzemanja izraza kot takega iz nemščine ali pa odraz stereotipnih predstav Slovencev o drugih narodih in ne odraz rivalstva med Slovenci in drugimi narodi.

Origines et étapes de la diversité des techniques sidérurgiques en Afrique de l’Ouest : le cas de la production du fer en pays bassar (nord du Togo) du XIIIe au XXe siècles
Authors: Robion-Brunner Caroline , Coustures Marie-Pierre , Dugast Stéphan , Tchetre-Gbandi Assouman , Béziat Didier
Published: December 2022

La production de fer a joué un rôle clé dans l’histoire de l’Afrique depuis plus de 3 000 ans. L’étude de cette activité humaine a démontré son importance exceptionnelle, sa profondeur historique et une étonnante variabilité des pratiques. En effet, les métallurgistes ont développé différentes manières de produire du fer en Afrique subsaharienne. Ils ont multiplié les choix techniques à un degré inégalé sur les autres continents.La région de Bassar (nord du Togo) abrite un des centres de production du fer les plus anciens – la sidérurgie y débute au ve siècle avant notre ère – et les plus importants d’Afrique de l’Ouest – environ 50 000 tonnes de fer y ont été produites entre le xiiie et le xxe siècle. De récentes recherches menées dans le cadre du programme international et interdisciplinaire SidérEnT (2014-2018) y ont révélé l’existence de plusieurs procédés techniques pour réduire le minerai de fer. Afin de comprendre quels facteurs pouvaient être à l’origine de cette diversité technique, nous avons adopté l’approche la plus holistique possible. Ainsi, après l’établissement d’un bilan exhaustif des données géologiques, archéologiques, archéométriques et ethnologiques à notre disposition, nous évaluons les différentes possibilités pouvant expliquer la pluralité des pratiques, puis nous proposons différents scénarios historico-culturels retraçant l’évolution des techniques sidérurgiques en pays bassar.
The Rebranding of Newcastle as a Smart City. Cui Bono?
Authors: Avril Emmanuelle
Published: December 2022

The city of Newcastle, regional capital of North East England and home to “the UK’s smartest street” located a short distance from its brand new Helix district, is described as having successfully transitioned from a traditionally industrial city to a “smart” city, able to use digital tools to address issues such as congestion, pollution, waste reduction and parking, with the dual objective of “helping people to live better lives” and of making the city more attractive to businesses, investors, international students, and tourists. While ubiquitous in political and academic discourse, the idea of “smart city” is strikingly absent from general public discussion, with very low awareness among those whose lives are supposed to be most improved. Criticisms of smart cities tend to focus on the fact that the services associated with smart cities constitute a very lucrative market, on the lack of residents’ involvement in changes that will directly affect their everyday life, and on the potential for misuse of the data collected. Drawing primarily from a range of published material such as policy documents, newsletters, working papers, announcements, websites, and brochures produced by the key players of the smart city, as well as from conversations with ordinary residents, this article aims to contribute to the discussion on smart cities by confronting official discourses with “actually existing” practices, through the case of the mid-sized city of Newcastle. It explores the uses of smart city tools and discourse to rebrand the city of Newcastle and revitalise civic pride, setting the smart city promises against actual improvements to the lives of local residents as well as their perceptions of their city. The first section of the article sets out the elements of the smart city to show how the characteristics of the city of Newcastle made it an ideal terrain for experimentations; the second section analyses the deployment of the smart city agenda in the city, focusing on the discourses and perceptions of the range of players involved. The third and final section seeks to understand who is set to benefit the most from Newcastle’s transition to a “smart city”. The conclusion presents a nuanced assessment of the potentialities and limits of the smart city.

Le but de cette expérience est d’initier les étudiants aux méthodologies actives par le biais d’une démarche pédagogique en trois étapes : i) recherche documentaire de cinq articles scientifiques portant sur une méthodologie active au choix (pédagogie inversée, apprentissage par projet ou par le jeu, entre autres) ; ii) restitution de cette recherche documentaire sous la forme d’une carte heuristique ; iii) élaboration d’un pitch audiovisuel et conception d’un scénario d’enseignement/apprentissage en ligne relevant de la pédagogie active sélectionnée. En mobilisant une vaste panoplie d’outils numériques, les étudiants s’initient, comme nous tâcherons d’en rendre compte, à de nouveaux espaces d’enseignement/apprentissage qui impliquent un dialogue productif entre recherche et pratique en didactique des langues à l’ère du numérique.
Role of the Advanced Practice Registered Nurse in Crisis Response
Authors: Henry Kiersten , Wogatske Alison
Published: December 2022

As clinical leaders, advanced practice registered nurses are often called upon to respond to crises. Although frameworks for emergency preparedness and response have been established by the National Organization of Nurse Practitioner Faculties and the International Council of Nurses, the advanced practice registered nurse community is not consistently prepared to participate in crisis response. Merging of the previously established frameworks allows identification of additional opportunities for advanced practice registered nurses to be educated and engaged in emergency preparedness and all-hazards response, including preparation activities, communication, safety and security, incident management, assessment, intervention, and recovery. Additional areas of focus are leadership, ethics, and end-of-life care. Use of the existing frameworks combined with the lessons learned from the COVID-19 response can empower advanced practice registered nurses to improve their readiness to respond to future crises.

Change of the profession or form of its practice from the perspective of the professional ethics of attorneys-at-law
Authors: Ciupa Sławomir W.
Published: December 2022

The article discusses issues related to the professional mobility of attorneys-at-law in light of the Code of Ethics of Attorneys-at-Law. The author discusses changes in the profession or form of its practicing in terms of movement between the public and private sectors as well as within the private sector itself. The article also addresses the issue of changing the form of practicing the profession or the entity where the profession is practiced. These phenomena, though partially regulated by law, escape ethical regulation; the Code covers them only to a narrow extent (professional secrecy and conflict of interest). The question is, therefore, whether this and the indirect application of several other principles of professional ethics (independence, dignity of the profession, loyalty, and trust) can be considered appropriate. The author analyzes if the application of the above ethical principles is sufficient in terms of safeguarding against the unethical use of relationships or networks from the professional past as well as avoiding the related reduction in independence, conflicts of interest, breach of professional secrecy, or loyalty.

Authors: Lima João Paulo Eufrazio de
Published: December 2022

O objetivo deste artigo é realizar uma análise da campanha de desinformação promovida pelo Governo Federal brasileiro a favor do uso de cloroquina como parte do denominado “tratamento precoce” contra a Covid-19. Para tanto, analisamos as menções ao tratamento com cloroquina feitas pelo Presidente da República Jair Messias Bolsonaro, principalmente em suas lives no Youtube. Para verificar a capacidade de alcance dessas falas presidenciais, buscamos correlacionar as referidas lives aos índices de busca pela palavra-chave “cloroquina” no site de buscas Google, através da ferramenta Google Trends. Os dados obtidos demonstram que é possível estabelecer uma relação entre as menções feitas à cloroquina pelo Presidente da República e o aumento significativo pela busca desse termo no site de buscas Google. Além disso, a alta recorrência do discurso a favor do chamado “tratamento precoce” indica que também houve uma campanha desinformativa orquestrada de forma a enganar ou confundir a opinião pública com consequências graves ainda a serem investigadas.

Authors: ATEŞ Ali Murat
Published: December 2022

A 30 kWp rooftop solar photovoltaic (PV) power plant was modelled using energy balance equations, 3-year energy production and its economic return is calculated according to the feed-in tariff agreement. Hourly measured electricity generation and Excel spreadsheet simulation results were closely compatible. The system generated 45.35 MWh, 47.05 MWh and 46.34 MWh of energy in year 1, 2 and 3, respectively. It has been observed that the performance ratio of the PV system varies between 84.50 % and 90.27 %, while the capacity factor varies between 17.26 % and 17.63%. While 93.90 MWh of electrical energy has been injected into the grid over a 3-year period, 46.40 MWh of energy has been taken from the grid. The price of electricity injected and consumed was calculated according to the FIT conditions at the time the system was installed, and the payback period was calculated as approximately 6 years.

Authors: Chai Ali Ali , Renatus Mligo Ignasia , Shaghembe Nsolezi Florentina
Published: December 2022

This study explored educational stakeholder’s perceptions on the provision of PPE in Zanzibar, using the case study design. The target population was pre-primary school teachers, pre-primary school head teachers, quality assurance officers from the Ministry of Education and parents. A total number of 20 participants participated in the study: 6 pre-primary school teachers, 3 pre-primary school head teachers, 5 quality assurance officers from the Ministry of Education and 6 parents. The study employed the semi structured interviews which were conducted to PPE teachers, head teachers and quality assurance officers and Focus group discussions with teachers. The study established that PPE plays important roles to young children as it enables them to lay their educational foundation for future development, improving self-confidence and providing strong base for lifelong learning and cognitive, physical and social development. However, the quality between one PPE school to another differ in terms of teachers qualification, resources and facilities, school management and learning environment. The study recommends that professional development training for pre-primary school teachers be conducted and maintained. Such trainings should be handled by PPE experts. This would improve the knowledge, skills and performance of teachers on pedagogical skills to ensure the supportive teaching in PPE for better learning of children. Finally, Quality Assurance Officers should constantly monitor the quality of pre-primary education in order to ensure that schools meet the required standards for better teaching and learning in PPE.

Authors: Saleh Moh’d Salma , Uwamahoro Prof. Jean , Aluko Orodho Prof. John
Published: December 2022

This study sought to establish the effect of representations strategies on Secondary School students’ Mathematics Achievement in Unguja Island, Zanzibar. Four out of sixteen public secondary schools located in the urban district of Unguja Island were randomly selected. Two of these schools were assigned as the experimental group while the other two were the control group. Participants were students from level three who were sampled based on the type of group to which the school is assigned. Achievement tests (pre-test and post-test) based on mathematics topics of relation and function were used as an instrument for data collection. Data was analyzed quantitatively in terms of descriptive statistics and t-tests. The study established no initial difference in performance between the control and the experimental groups. After the intervention, the experimental group which used multiple representation strategies outperformed the control group. Therefore, the study recommends that teachers should implement multiple representation strategies during the mathematics teaching. Additionally, teachers should be provided with in-service training on proper utilization of varieties of representation strategies in teaching and learning of mathematics for better results to be realized.
Impact of Cash Transfer on Poverty Reduction in Lindi District, Tanzania
Authors: O. Njuga Gidion , Kazuzuru, PhD Prof. Benedicto , B. Warsanga, PhD William
Published: December 2022

Cash Transfers (CT) as a strategy for poverty reduction acquired prominence in Latin America but spread later to the rest of the developing world including Tanzania. Government through its umbrella institution, Tanzania Social Action Fund (TASAF) introduced what has become the largest CT for poor households in the country since 2010 to date. Although there is growing evidence on the impact of CT on poverty reduction, results are contextual. Thus, the paper examined the causal effect of CT on poverty reduction in Lindi District, Tanzania. Specifically, the study assessed the impact of CT on households’ overall wealth, housing conditions, use of basic services, productive and non-productive assets. The study employed Propensity Score Matching (PSM) to estimate the effects of CT on households by matching recipients and non-recipients’ households using Nearest Neighbor, Radius caliper and Mahalanobis matching techniques. Sample size constituted 398 respondents, split into equal number of recipients and non-recipients’ households. Five Focus Group Discussions (FGDs) and 13 Key Informants Interviews (KIIs) were conducted. Qualitative data was analysed using content analysis. Findings indicated that CT to poor households by itself is not enough to significantly reduce extreme poverty. However, the results indicated significant effect of CT on five poverty indicators which are type of floor, sanitation facilities, livestock, mobile phone and chair. The study recommends to government adoption of multi-intervention programs directed on key living standard indicators such as productive assets to transform the quality of low-income households.
Clients' Perception of VICOBA Informal Social Security Roles: The Case of Nambis Division in Mbulu District, Tanzania
Authors: Magali, PhD Joseph , Barhe Reginald
Published: December 2022

The study sought to establish clients’ perception of Village Community Banks'(VICOBA) informal social security role in the Nambis division of the Mbulu District, Tanzania. The concurrent mixed-method designs were applied concomitantly with stratified and systematic sampling to select 124 clients for the study. The semi-structured questionnaires were used to collect data from 9 VICOBA groups located in 4 wards of the Nambis division. The quantitative data were analysed using the descriptive and Ordinary Least Square (OLS) regression analysis while the qualitative data was analysed using relational content analysis. The findings demonstrated that VICOBA played the informal social security role of prevention and protection, promotion of essential goods and services’ accessibility and fostering of opportunities and potentials positively and significantly. The study recommends the government formulate a policy which recognizes VICOBA’s informal social security functions. This will enable VICOBA to perform their informal social security roles effectively.

Published: December 2022

The purpose of the study was to examine the effect of non-monetary rewards on employees’ performance in Mount Meru Referral Hospital in Arusha, Tanzania. The sequential parallel design was employed to carry out the study. The target population was 355 while the sample size was 188 which included 8 managerial workers and 180 non-managerial employees of the hospital. Questionnaire and interview guide were used for data collection. The quantitative data was analyzed using both descriptive and inferential statistics while the qualitative data was thematically analyzed. The study established that non-monetary rewards such as employee recognition, training, development, employee independence and flexible work schedules have a positive effect on the employees’ performance. The practice of flexible working schedules currently in place in the hospital needs to be retained for effective job performance to be realized. The management of the hospital should get employees trained and re-trained so as to enhance their performance in terms of service delivery to patients.

Artículo de reflexión | Publicaciones científicas: ¿El conocimiento como un mercado o como un bien común
Authors: Caballero Carlo Vinicio , Fajardo Estefanía
Published: December 2022

Las publicaciones científicas se han convertido en el vehículo preferido para dar a conocer los avances en el campo de la ciencia. En las últimas décadas ocurrieron cambios importantes relacionados con la difusión del conocimiento científico y, además, surgieron con fuerza los movimientos del acceso abierto y lo que se ha denominado ciencia abierta. Así mismo, estos cambios han generado una modificación conceptual respecto a lo que fueron las publicaciones científicas, lo que representan en la actualidad y hacia dónde pueden dirigirse en el futuro. También los avances tecnológicos han permitido que cada vez sea más fácil y menos costoso compartir el conocimiento, situación que, sin duda, está influyendo en el desarrollo de estas publicaciones. En este artículo de reflexión describiremos los fenómenos que se han presentado en torno a la difusión de la ciencia, y realizaremos un análisis de la información disponible para, posteriormente, radiografiar el presente de las publicaciones científicas y proyectar lo que sería el futuro inmediato de esta importante actividad editorial. Inicialmente, describiremos los orígenes de la publicación científica, sus logros y el establecimiento de una industria con un mercado, así como la existencia de un emporio del prestigio y los movimientos que abogan por un cambio en la visión comercial del sector para que se atienda más la ciencia como un bien común. Además, revisaremos el papel de las publicaciones científicas en América Latina y los retos y desafíos de una industria cuyo producto principal es el conocimiento.

Yüzey suyu ile yer altı suyu arasındaki ilişki oldukça karmaşıktır ve bu ilişki-nin modellenmesi pek de kolay olmayan bir süreçtir. Bu çalışmada, yüzey suyu-yer altı suyu arasındaki ilişki Mersin İli Silifke İlçesine bağlı Göksu Del-tası için modellenmiştir. Bunun için, Amerika Birleşik Devletleri Jeolojik Araştırmalar Kurumunun (USGS) geliştirdiği PRMS (Yağış-Akış Modelleme Sistemi) ile MODLFOW-2005’in (Modüler Yer Altı Suyu Akım Modeli) en-tegrasyonu ile oluşturulan GSFLOW (Yer Altı Suyu-Yüzey Suyu Akım Modeli) kullanılmıştır. Modelin kalibrasyonu yapılırken öncelikle PRMS ve MODFLOW-2005 kalibre edilmiş, daha sonra GSFLOW’un kalibrasyonu yapılmıştır. MODFLOW-2005’in kalibrasyonu, arazide ölçülen yer altı su seviyeleri ile modelleme sonucu elde edilen seviyeler karşılaştırılarak yapılmış-tır. Bunun için bir yıl boyunca, sahada tespit edilen on sekiz kuyuda aylık olarak statik yer altı su seviyeleri ölçülmüştür. Yatay ve düşey hidrolik iletkenlikler kalibrasyon parametresi olarak kullanılmıştır. Çalışma ile Göksu Deltasının yüzey suları ile yer altı suyu arasında daimî ve değişken bir ilişki olduğu sonucuna varılmıştır.

Comparative Evaluation of Prediction Model between Inference Fuzzy System and Universal Kriging for Spatial Data
Authors: Mahmood Dhaher Ghanim , Ibrahim Ibrahim Abdulghany
Published: December 2022

This paper dealt with one of the spatial interpolation methods in the geostatistics field. The purpose of this research is to get the parameters of unbiased estimators based on regionalized random variables in spatial statistics. In this paper, we used universal kriging with the fuzzy inference system by the Mamdani technique. the objective of this work is to estimate the parameters of covariance functions relying on spatial real for the depth of groundwater in Mosul city, Iraq. The data adopted contains (100) real data with locations representing the depth. From the results we show the best model with the constructs of weights, we illustrate the performance of universal kriging is the best when corresponding with the fuzzy system. In conclusion, the improvement of any method of spatial interpolation or fuzzy system does not depend on more statistical structures but depends on the efficiency of the method which satisfies the conditions of weights and minimum variance errors. All programming is applied by Matlab language.
