Implications of the Forces Equipment with New Weapon Systems on the Combat Power Morale Component
Authors:   Major, Superior Instructor, PhD Candidate, Command and Staff Faculty, “Carol I” National Defence University, NISTORESCU Claudiu Valer
Published: June 2023

Today’s modern battlefield requirements impose more than a simply convenient force concentration in order to accomplish the mission and obtain a military success. Definitely, the factor of morale remains a force multiplier and an essential element of combat power. In this regard, we highlight that by equipping military forces with modern and performing weapon systems we can obtain a significant combat power increase. The superiority with respect to this military action’s dimension ensures the premises not only for a physical destruction of the opponent, but also for shattering its cohesion and will to fight. Tactical forces’ proper equipment in terms of quantity and quality generates results not only for the combat power’s physical component, but also for its morale component. Therefore, my opinion is that the maintenance of morale is strictly related to the quality and reliability of providing forces with new weapon systems and other military equipment.
Romanian Naval Forces Contribution to Strengthening Romania’s Profile as a Proactive Security Provider in the Black Sea Region
Authors:   Chief of the Romanian Naval Forces, PANAIT Mihai
Published: June 2023

Nowadays, because of growing uncertainty and instability in the context of a changing geopolitical system, we should reconsider the Wider Black Sea Region as a place in which frictions between cultural, political and economic divergent communities would be more predominant. In addition, there are the consequences of globalisation that create a factual interdependence of countries geographically far away, when the effects of local crisis are immediately perceived at the worldwide scale. Countries around this region, and not only, rely on the maritime domain for trade, economic development, food, job and other types of security. In this context, the latest actions of the Russian Federation in Ukraine and the militarisation of Crimea have substantially modified the framework of security strategies in the area. The numerous frozen conflicts, due to Russian policy, represent a real threat across the region. With the Crimean Peninsula, Russia is able to extend its military reach over much of the Black Sea maritime domain, the South Caucasus littoral, Ukraine, Moldova, and, possibly, far beyond over Romania, Bulgaria and Turkey
The Authentic Leader and Psychological Capital in the Military Environment
Authors: ANTONESEI Marcela , FĂSĂREA Simona
Published: June 2023

“Authentic leadership” is a significant area of research. Based on the theory, which explains how individuals establish a social and professional relationship, we have postulated a statistical relationship between authentic leadership and psychological capital. Thus, the implications of this type of relationship for theory and practice are discussed in the paper. In this study, we intend to conduct an exploratory study to demonstrate not only the role of authentic leadership in the military organization, but also how it is achieved. The study aims to identify whether there is a significant relationship between authentic leadership and psychological capital. Why is such research important in the military environment? Because military leaders can motivate subordinates both inside the organization and outside the chain of command. Being an authentic leader is much more complex than simply “giving an order”. An authentic leader’s influence on other colleagues or subordinates can take many forms.
The Question of the Bosporus and the Dardanelles Straits
Authors: CUCOȘ Cezar
Published: June 2023

"The struggle for control of the Bosporus and the Dardanelles, strategic access points on the only waterway between the Black Sea and the oceans of the world, has a long history. It has become even topical in the modern age, as an effect of the increase in economic power and the expansionist tendencies of some states, bearing the imprint of the flourishing or decline of some empires whose fate depended on the strategic situation at the junction of Europe and Asia. However, 86 years ago, in a conciliatory setting, a diplomatic instrument was signed in Montreux, emblematic in the evolution of international law, based on a real spirit of harmonization of political, economic and military interests, which authorized the transit of ships and aircraft through the area of the Bosporus and the Dardanelles straits. Still in force today, the Montreux Convention signed on 20 July 1936, which put Ankara in possession of the keys to the straits, is one of the long-lasting international agreements, limiting the number and tonnage of vessels and, in the case of warships, the duration of their presence in the area, a fact that, in the almost nine decades, has produced effects on the interests of some states, be they Black Sea littoral states or not. The current war in Ukraine, launched on 24 February 2022, brings back in the diplomatic debates the document whose articles relating to the conflict situation have not been invoked since the end of the Second World War, although, over time, interested parties have strongly advocated for the revision of the Montreux Convention."

Las cofradías, hermandades y guachivales fueron instituciones dedicadas a un santo que llevaban a cabo actividades sociorreligosas. Estas consistían en la realización de las procesiones, misas y festividades en torno al santo. Recaudaban fondos para poder pagar todos los gastos que tenían a su cargo. Las cofradías y hermandades estaban adscritas a la parroquia, mientras que los guachivales estaban ligados a un linaje indígena. Los quijovales eran una institución que agrupaba a los linajes del pueblo de Santa María de Jesús en las faldas      del volcán de Agua. En este trabajo se da a conocer cómo funcionaba cada una de ellas,      así como las      actividades que realizaban. Se hace mención específica de algunas que existieron en      la Antigua Guatemala y los pueblos vecinos a finales del siglo XVIII y principios del siglo XIX.
La tergiversación de la narrativa histórica en Guatemala
Authors: Sabino Carlos
Published: June 2023

El artículo describe la forma en que dos importantes instituciones elaboraron una especie de «historia oficial» sobre el conflicto armado interno que sufrió Guatemala en la segunda mitad del siglo XX. Después de exponer las principales características que tuvo dicho enfrentamiento se pasa a describir, en detalle, la forma en que fue presentado por la Comisión del Esclarecimiento Histórico de la ONU y la Oficina de Derechos Humanos del Arzobispado de Guatemala para construir un relato totalmente favorable a la guerrilla. Se concluye resumiendo las consecuencias políticas y jurídicas que tal tergiversación ha tenido en años posteriores.

This study investigated the use of anaerobic biodigestion as an ecological technique for treating organic waste in urban solid waste. Biogas production is carried out through the action of microorganisms, and the use of enzymatic hydrolysis can increase biogas production, although it presents economic challenges. The aim of the study was to pre-select microbiological groups and enzymes to optimize the process and increase biogas production using statistical tools. Organic waste from a restaurant and sludge from a sewage treatment plant in Brazil were used, and three bacterial strains and 12 groups of microorganisms, as well as commercial enzymes, were evaluated. The study was divided into four stages to reduce the number of independent variables and increase the accuracy of methane and biogas production results. The results indicated that careful selection of microbial groups had a significant positive impact on biogas and methane production. The interaction between pre-selected groups of microorganisms and enzymes resulted in significant positive effects on cumulative biogas and biometane production. The study concluded that careful selection of microbial groups is essential to maximize biogas production and the efficiency of the anaerobic digestion process. Further, a more detailed identification of microorganisms and their interactions is needed to further optimize biogas production. In general, the appropriate choice of microbial groups is fundamental to the success of anaerobic digestion and biogas production.

Authors: Pereira Valentina da Silva Dias , Pereira Antonio Renaldo Gomes
Published: June 2023

O artigo visa refletir sobre um ritual de purificação realizado durante os ritos fúnebres em comunidades tradicionais do sertão baiano, nos quais a socialização e os tabus levantados em consequência da proximidade dos vivos e dos mortos ganham a cena. Buscamos refletir sobre a ressignificação de uma atividade de limpeza do ambiente doméstico, ritual aplicado como atividade própria para o banimento do espírito do morto, bem como dos possíveis perigos representados pela morte e a presença do corpo morto. Para tanto, realizamos entrevistas semiestruturadas via WhatsApp com moradores de três comunidades tradicionais do sertão da Bahia a fim de apreender as ideias centrais desta atividade ritual. Constatamos que os rituais fúnebres têm papel significativo no que condiz à socialização das comunidades sertanejas baianas. Ao passo que evidenciamos a busca por purificação e restabelecimento do cotidiano após o contato ritualizado entre o mundo dos vivos e o mundo dos mortos.
The Commonwealth Caribbean Women’s Movement in a Post-Colonial Mould: A Route Back to Conscience
Authors: Myrie Marsha Hinds
Published: June 2023

Women in Barbados and the Commonwealth Caribbean have always organised to oppose and change their circumstances. Given the prevalence of misogyny and patriarchy in colonial and postcolonial societies, this resistance is especially important. Women’s activism has primarily been labelled as “feminism,” but this paper contends that this is not historically accurate. While feminism provided a language and an international platform for Caribbean women’s work, it was ineffective in providing a framework for addressing community-based organising. The paper employs Eusi Kwayana’s concept of “conscience” as a more appropriate philosophical anchor for Caribbean activism. Conscience is a philosophical marker that connects Andaiye’s work to a broader Afro-Caribbean approach to navigating life in postcolonial societies affected by the relics of slave plantation economy and social structures. This orientation runs counter to the Western definition of feminism, and Caribbean women should be wary of the ways such concepts impede their ability to organise themselves meaningfully.

Published: June 2023

A technique for lateral ow hybridization analysis of speci c bacterial beta-lactamase mRNAs has been developed, including the preparation of a biotinylated target DNA and its analysis on a test strip with immobilized oligonucleotide probes. When the DNA target and probe structures are complementary, DNA duplexes are formed in the test zone of the strip, which interact with the streptavidin conjugate with gold nanoparticles. The method was used to determine the transcripts of the TEM-type betalactamase genes isolated from the culture of E. coli - producers of the corresponding recombinant betalactamase. It has been shown that singlestranded DNA target of 330 bases was revealed most effectively in lateral ow analysis.

Authors: MIKHAILOVA ANASTASIA YU. , BUDANOVA ULYANA A. , YURII L. SEBYAKIN
Published: June 2023

Low molecular weight RGD peptides and RGD mimetics are widely studied as ligands targeting the corresponding receptor in the diagnosis and therapy of cancer, as well as in the eld of bone tissue regeneration. Some of them are undergoing preclinical trials. The aim of this work is to select optimal variants of the ligand structure based on an aliphatic RGD mimetic. By methods of molecular modeling (“blind” docking and active site docking), the most advantageous constructions for the formation of a stable complex with the integrin αVβ3 were determined. A scheme was developed and the synthesis of two lipotripeptides Gnd-GABA-Gly-Asp(C16)2, Gnd-β-Ala-Gly-As-p(C16)2 with the potential ability to inhibit this receptor on the surface of tumor tissues was carried out.

The effectiveness of drug penetration into the inner tissues of the eye is signi cantly limited by the barrier effect of the cornea and by the washing out of a drug with tear uid. To increase the bioavailability of the drug, it was proposed to include the drug in chitosan particles formed by two types of chitosan - 5 kDa chitosan and 72 kDa glycol-chitosan. Chitosan particles with incorporated angiotensin-converting enzyme inhibitor enalaprilat, capable to reduce intraocular pressure, were characterized by dynamic light scattering and scanning electron microscopy. Particles formed by 5 kDa chitosan had an average hydrodynamic diameter of 85-125 nm and a positive ζ-potential of +21±3 mV, while particles formed by 72 kDa glycol-chitosan were 440-480 nm by size and had ζ-potential of +10±2 mV. The percentage of inclusion of enalaprilat in chitosan particles was 25% and 40%, respectively. In vivo experiments have shown that the inclusion of the drug in chitosan particles increased the retention time of enalaprilat in the lacrimal uid of rabbits.

Our earlier annotation of genome of the yeast Ogataea parapolymorpha DL-1 made it possible to identify ve genes of potential D-amino acids oxidases. All opadaao1 - opadaao5 genes were cloned and expressed in E. coli. Four OpaDAAO1- OpaDAAO4 enzymes were obtained in highly puri ed form and their catalytic properties were studied. It was found that among all DAAOs described in the literature so far, the enzyme OpaDAAO1 has the highest catalytic constant kcat with D-Ala, which makes it promising for practical applications. However, in addition to good catalytic parameters, effective application of the enzyme in practice requires high stability and knowledge of the inactivation mechanism, including at elevated temperatures. In this work we studied the effect of elevated temperatures on the stability of OpaDAAO1. The enzyme was shown to have high thermal stability in comparison with majority of other D-amino acid oxidases. The kinetics of OpaDAAO1 inactivation at different temperatures, initial concentrations of the enzyme, and in the presence of exogenous FAD were studied. A possible kinetic scheme of inactivation was proposed based on the data obtained.

Peptidomimetics are small molecules that are able to mimic the functional and structural features of peptides. The application of rational design during the development process allows their use as effective antibacterial agents with improved pharma-cokinetic properties. In this work, we have constructed a series of cationic amphiphiles based on the alkyl-indole derivative of L-serine, differing in amino acid composition in the polar block and have potential antimicrobial activity. A universal preparation scheme has been developed, which makes it possible to obtain target compounds in quantities necessary for further study of biological properties. Based on the analysis of antimicrobial activity, it was found that structures with a higher lipophilicity value and a smaller polar block volume demonstrate the best results.

Authors: RASTRIGA NIKOLAY V. , GASANOVA DARIA A. , LEVASHOV PAVEL A.
Published: June 2023

For human and chicken lysozyme , the relationship between changes in the parameters of enzyme adsorption on living Escherichia coli bacterial cells and the value of its effective bacteriolytic activity in the presence of glycine and charged amino acids was studied . It has been shown for both human and chicken lysozyme that free amino acids added to a concentration of 1.5 mM for glycine or 5.0 mM for glutamate, aspartate, histidine, arginine, and lysine reduce the desorption constant of the enzyme on bacterial cells to 1.4-2.0 times. At the same time, an increase in the bacteriolytic activity of lysozyme is also observed in 1.5-1.9 times. Thus, the enhancement of antibacterial activity in the presence of glycine and charged amino acids can be explained by an improvement in the productive sorption of the enzyme on the substrate, bacterial cells.

E. coli strains have been created as producers of recombinant β1-adreno-receptor epitopes as part of chimeric proteins. The corresponding epitope sequences are located in the C-terminal region of the human heart fatty acid binding protein (hH-FABP) and separated from it by a linker sequence (Gly4Ser)3. A solid-phase enzyme-linked immunosorbent assay (ELISA) for detection of autoantibodies against β1-adrenergic receptor in human blood serum based on a recombinant epitope has been developed. Blood sera of patients (N = 76) with various diagnoses of cardiopathologies and other diseases were analyzed. In some patients with a con rmed diagnosis of cardiovascular diseases, a signi cantly increased level of autoantibodies to β1-adrenergic receptor was detected, in most cases those with a diagnosis of acute myocardial infarction.

Published: June 2023

The onset of the digital age has led to the rapid development of translation technology. Nowadays, not only specialists in natural languages but also those in applied translation studies keep a close eye on machine translation research. This article examines research papers on translation technology in the humanities and social studies in Russia and China: based on the papers by Russian and Chinese specialists in translation studies, the author conducts a comparative analysis of the evolution and scientific achievements in this field, reveals their common and unique features. For instance, following current trends, Russian scientists offer a new perspective on the development of translation technology based on the concept of “digital translation” that relies on the introduction of modern technologies, in particular computeraided translation (CAT). On the other hand, following the idea of aparadigm shift in translation studies, Chinese scientists o er a new scientific approach expressed in the concept of the “technological shift”. Thus, the fusion of the new approach and a new perspective can contribute to further substantial improvement in translation technologies.

O modal rodoviário representa a maior parte da logística de transporte de cargas do nosso país, seja de pessoas ou de mercadorias. No entanto, segundo dados da Confederação Nacional do Transporte (CNT, 2021), apenas 12,3% das rodovias brasileiras são pavimentadas, além de que, dentre essa reduzida malha pavimentada, a maior parte apresenta patologias que dificultam o transporte, causando elevação nos custos, que poderiam ser solucionados com ações de manutenção. Deste modo, esse artigo objetiva estudar as condições atuais do pavimento da rodovia BA – 262 localizada na região do município de Ilhéus e inserida no contexto do Complexo Intermodal Porto Sul. Para isto, são utilizados dois métodos distintos: Levantamento Visual Contínuo, normatizado pelas DNIT 008/2003 e o aplicativo Roadroid, criado por pesquisadores suecos, que quantifica o Índice de Irregularidades do Pavimento. Esta rodovia é de asfalto CBUQ que há tempos sofre com grande incidência de patologias e reparações mal sucedidas e superficiais. Desse modo, após análise detalhada da situação atual da rodovia, esta foi classificada como “péssima” de acordo com as metodologias utilizadas, onde a grande quantidade de trincas, buracos, remendos e deformações foram as principais causas da baixa qualidade da BA-262. Além disso, este trabalho pode servir como base para incipientes pesquisas e futuros estudos de alternativas de restauração do pavimento atual, considerando inclusive, o aumento do tráfego projetado com a instalação do novo Porto Sul.

Little research has been conducted to examine the participation and persistence of adult basic education students in northern and rural Canada. This explanatory sequential mixed-methods study was conducted with adult learners to address this research deficit. The study consisted of questionnaire and interview phases. Using thematic analysis, five themes were identified from the participant responses: (a) positive, supportive, personal touch; (b) situational hardships; (c) friendships and community; (d) campus Indigeneity; and (e) program resources. Situational hardships directly affected students’ program participation and persistence. A positive, supportive environment contributed to participation and persistence, while friends, community, and program resources influenced student persistence in the program. Participants identified campus Indigeneity and promotion of the program as areas for improvement.
Teaching International Students in a Difficult Time
Authors: Tavares Vander
Published: June 2023

The coronavirus (COVID-19) pandemic has forced instructors and students to work together under constantly evolving circumstances. The abrupt transition to online education has contributed to making the educational experiences of instructors and students more emotionally complex and intense. Growing attention has been directed toward understanding the challenges international students face and their impact on the students’ learning experiences, considering the unprecedented difficulties the global pandemic has posed for international student mobility. In this context, instructors are in a unique position to support international students. One way to do so is by being (more) empathetic. Empathy is important because it not only helps us feel for and with the other, but also improves the academic outcomes of students. This paper discusses the importance of empathy in teaching international students by expanding on the concept of teacher empathy. This paper also critically examines the experiences of international students in higher education in several domains of lived experience, such as the linguistic, academic, social, cultural, and psychological. Other aspects of empathy presented are its contagious nature and the concept of radical empathy. This paper concludes by highlighting the practical application of empathy in light of international students’ experiences.

In the era of regional autonomy, being a principal is no longer a career position but a political one. Managerial competence does not seem to be the main requirement to occupy this position. This study aims to analyze the implications of the madrasa principal’s managerial competence on the conduciveness of the teacher’s work climate. The informants for this phenomenological study consisted of the principal and teachers of the Lamakera State Islamic Junior High School, East Flores, Indonesia. The results showed that the madrasa principal had a good leadership vision, but because the management function in the madrasa program was not optimal, the madrasa principal's managerial competence was low. The teacher's work climate is not conducive because the principal's communication is not effective, madrasah teachers are divided into several groups, there is a lack of ratio of teachers to number of students, administrative work is mostly done by honorary and voluntary teachers, and the allocation of educational operational funds determined by the government is not in accordance with the needs of the madrasa. This research has implications for the need to appoint principals not only based on a training certificate for prospective principals but also on a credible fit and proper test taking into account achievement, experience, and good career paths.

Allelopathy is a common biological phenomenon by which one organism produces biochemicals that influence the growth, survival, development, and reproduction of other organisms. The aim of this study was to investigate the phytochemical screening of the various extracts of Kherchoun (Hertia cheirifolia) and the evaluation of antioxidant capacities, by the DPPH test (2, 2-diphenyl-1-picrylhydrazyl), and of their allelopathic effects, vis-à-vis the two species: Vetch (Vicia sativa L.) and triticale (Triticosecale wittm L.). Biochemical analysis results showed that the highest total lipid content was observed at the leaf level (9%). The aqueous extracts of the leaves are rich in polyphenols, with a rate of 268.67mg EAG/g MS, compared to the stems (242.67mg EAG/g MS). The levels of flavonoids are higher in the leaves (38.67mg EAG/g MS) but lower in the stems (24.75mg EAG/g MS). On the other hand, the highest total tannin content recorded at leaf level is 608.33 mg EAG/g MS and the lowest is recorded in the stems (505 mg EAG/g MS). In contrast, the aqueous extract of the stems has the highest condensed tannin content (0.049 mg EAG/g MS), compared to that of the leaves (0.036 mg EAG/g MS). The two extract .Both aqueous extracts of Hertia cheirifolia are endowed with good antioxidant abilities. CI50 =139.43 2.99a μg/mL at leaf level and CI50 =111.38 22.2a μg/mL at stem level.Concerning the allelopathic study, the results obtained showed that the two extracts (Leaves and stems) of Hertia cheirifolia exerted different effects on the germination parameters of weed seeds of vetch (Vicia sativa L.) and triticale (Triticosecale wittm L.). Indeed, the two extracts exerted very important inhibitory effects, vis-à-vis the two seeds tested, on the germination and development of the seedlings (length of the root and length of the aerial part), in a significant and dose-dependent way.

Comprehensive pre-surgical evaluation, proper radiographic examination and careful surgical intervention are necessary for long-term success of implants. This study highlights the importance of assessment of morphometric dimensions of alveolar ridge profile at the maxillary lateral incisor and premolar using cone beam computed tomography (CBCT) thereby reducing the complications during the clinical procedures like implant placement, mini-implants in orthodontic anchorage, para-endodontic surgeries.

A total of 58 CBCT scans were included in the study and divided into two groups. (group-A, 20-35 years; group-B, 36-50 years). The buccal and palatal thickness of the maxillary alveolar cortical plates were measured at the crest, mid root, mid alveolar housing area, and the apex of the root.

In the sample of 58 CBCTs, the cortical plate thickness at the crest of the premolars has a significant increased thickness when compared to the lateral incisor in both the age groups. The thickness of mid alveolar housing point of premolars has significant increased thickness than the lateral incisors of age group-B.

In this study, the recommendations based on the results were beneficial in providing information regarding the buccal and palatal bone thickness at the maxillary lateral incisor and premolar tooth regions in 21-35 years and 36-50 years age groups thereby preventing complications that occur while undergoing dental procedures.

Background: Obesity is a common health problem that restricts people’s daily activities. Many observational studies found that diverticulosis is a common complication for obesity and the prevalence of diverticulosis is increasing. However, the correlation between obesity and diverticulosis remains controversial. Aim: The primary aim of our study was to assess the prevalence and the association between overweight or obesity and the rate of diverticulitis (as diagnosed by CT scans). Methods: Our study was based on reviewing the medical records in a single medical center in Saudi Arabia over a period of 3 years. 342 patients diagnosed with diverticulosis and confirmed by colonoscopy and CT scan were included, with those ages above 18 years old receiving a health examination, measurement of percentage of body fat, blood test and colonoscopy at King Abdulaziz University. Results: Women with body mass index (BMI 30) had a greater risk of developing diverticulosis (PR, 1.58; 95% CI, 1.05–2.06) when compared to women with normal BMI. By gender, in patients less than fifty-one, occurrence of colonic diverticulosis was less in female patients compared to males (29% vs 45%, P=.06). However, in older ages there wasn’t clear difference among male and female patients in the prevalence of diverticulosis. Conclusion: 342 patients who underwent screening colonoscopies for diverticulosis, were included in our analysis. We found that the risk of colonic diverticulosis has an obvious correlation to obesity especially in women with BMI 30. When comparing by age, colonic diverticulosis was less predominant in premenopausal-age women compared with similar-age men. These findings may be due to female sex hormones that enhance diverticulosis development. Key words: colonic diverticulosis, obesity, metabolic syndrome, Saudi Arabia

Background: In the context of fertility, Doppler sonography is used to evaluate the blood flow to the uterus and ovaries. The blood flow to these organs plays a crucial role in the process of ovulation, fertilization, and implantation of the fertilized egg. Changes in the Doppler sonographic indices of the uterine and ovarian arteries can provide information about the blood flow to these organs and can help identify potential problems that may be affecting fertility. Objective: To evaluate the Doppler indices of uterine and ovarian arteries in fertile and infertile women and help clinicians develop more effective diagnostic and treatment strategies for infertility. Methodology: A cross-sectional Analytical study was conducted for a duration of 9 months at a Medics Dr. Amers, Lahore, Pakistan. The study included 150 fertile and 150 infertile females aged 18-45 and excluded all females using oral contraceptive and contraceptive devices. SPSS software version 25 was used to analyze the data. Results: Age of participants ranged between 19 to 43 years with a mean + SD age of 28 + 6.5 years. The mean + SD RI and PI of left ovarian artery was 0.48 + 0.03 and 1.1 + 0.13 in the fertile, 0.9 + 0.03 and 4.2 + 1.2 in the infertile group. The mean + SD RI and PI of right ovarian artery was 0.60 + 0.03 and 1.6 + 0.06 in the fertile, 0.8 + 0.01 and 3.0 + 0.4 in theinfertile group (Table 1) Overall, results shows that the four variables are significantly different between fertile and infertile groups, with higher values in the infertile group. Independent sample test showed statistical significance between RI and PI of right ovarian artery of both groups (P < 0.05). However, in left ovarian artery the values of PI in both groups showed a significance (P< 0.05) were as values RI are found to be insignificant (P > 0.05). Independent sample test showed statistical significance between RI and PI of right and left uterine artery of both groups (P < 0.05). The mean + SD endometrial thickness in fertile group was 11.0 + 2.6 mm it was 9 + 1.6 mm in infertile group (Table 3). Indicating a significant difference between the two groups (P < 0.05). Conclusion: Uterine and Ovarian artery hemodynamics plays an important role in fertility. Findings from this study revealed that a high RI and PI and thin endometrium significantly affects fertility. Key words: Resistive index, Pulsatility index, Infertility, Uterine artery, Ovarian artery.

The Astra User Interface Library
Authors: Furuti Carlos A.
Published: June 2023

Embora aplicações complexas exijam interfaces eficientes com o usuário, sistemas gráficos básicos não são adequados à sua implementação sistemática. O uso de bibliotecas (toolkits) reduz o esforço de construção oferecendo elementos de interface (widgets) padronizados e pré-definidos. STK é uma proposta de toolkit simples e portável suportando workstations gráficas e terminais convencionais. Uma aplicação usando STK teria um único código-fonte, podendo ser usada com interfaces similares em ambas as plataformas. O módulo gráfico Astra, já implementado e em avaliação em sistemas UNIX, é apresentado neste texto. Astra é flexível e pode ser estendida. Futuramente uma ferramenta poderá editar graficamente interfaces STK criando automaticamente código de interface para dispositivos gráficos e textuais.
