Mayaro virus (MAYV) is an arthropod-borne virus (arbovirus) belonging to the family Togaviridae, genus Alphavirus. In recent years, the geographic distribution of MAYV may have expanded north from South and Central America into the Caribbean Islands. Although Haemagogus janthinomys is considered the main vector for MAYV, the virus has also been isolated from other mosquitoes, including Aedes aegypti, a widespread species that serves as the main vector for highly epidemic viruses. Given the possible expansion and outbreaks of MAYV in Latin America, it is possible that MAYV might be adapting to be efficiently transmitted by urban vectors. Therefore, to investigate this possibility, we evaluated the vector competence of Ae. aegypti and Ae. albopictus mosquitoes to transmit MAYV isolated during a year of low or high MAYV transmission. Adult Ae. aegypti and Ae. albopictus were orally infected with the MAYV strains, and the infection, dissemination, and transmission rates were calculated to evaluate their vector competence. Overall, we found higher infection, dissemination, and transmission rates in both Ae. aegypti and Ae. albopictus mosquitoes infected with the strain isolated during a MAYV outbreak, whereas low/no transmission was detected with the strain isolated during a year of low MAYV activity. Our results confirmed that both Ae. aegypti and Ae. albopictus are competent vectors for the emergent MAYV. Our data suggest that strains isolated during MAYV outbreaks might be better fit to infect and be transmitted by urban vectors, raising serious concern about the epidemic potential of MAYV.

A note on limits of sequences of binary trees
Authors: Grübel Rudolf
Published: May 2023

We discuss a notion of convergence for binary trees that is based on subtree
sizes. In analogy to recent developments in the theory of graphs, posets and
permutations we investigate some general aspects of the topology, such as a
characterization of the set of possible limits and its structure as a metric
space. For random trees the subtree size topology arises in the context of
algorithms for searching and sorting when applied to random input, resulting in
a sequence of nested trees. For these we obtain a structural result based on a
local version of exchangeability. This in turn leads to a central limit
theorem, with possibly mixed asymptotic normality.

Authors: Schwieterman Jaclyn , Welch Michael , Breitbach Anthony
Published: May 2023

Background: Interprofessional education and collaborative practice are standards that have been added to the accreditation standards for athletic training education. Athletic training educators will need to provide interprofessional experiences to their students to remain compliant with the standards. The goal of the mixed methods study was to explore athletic training preceptors' perceptions of interprofessional education and collaborative practice in the clinical setting. Methods: A total of 34 athletic training preceptors completed the full online survey, and of those, 5 completed the semi structured interview. Participants completed an asynchronous online module and a retrospective pretest survey using the ISVS-21 about their beliefs, behaviors, and attitudes about interprofessional education and practice. Participants that volunteered were asked additional questions during a semi-structured interview. Results: The findings of this study found that the educational module was effective in increasing the beliefs, behaviors, and attitudes of athletic training preceptors with a short online module and that preceptors had positive attitudes/beliefs about IPE/IPCP, however, preceptors identified lack of education about IPE/IPCP and barriers to implementing IPE/IPCP with and without students that influenced their use of IPE/IPCP. Conclusion: Athletic training programs could educate and develop athletic training preceptors in interprofessional education and clinical practice to help develop opportunities for athletic training students in the clinical setting.

Published: May 2023

Purpose: E-assessment is a novel practice in developing countries; hence it is essential to determine the online platforms and tools preferred by health sciences education faculty for online assessment. The purpose of this study was to assess the preference of faculty in medical and dental education regarding the online tools for e-assessment of undergraduate students. Methods: This cross-sectional, descriptive study was conducted from June until August 2020 on the faculty of medical and dental undergraduate programs of private and public sector institutes across Karachi, with a sample size of 152. Data was collected through convenience sampling using a validated questionnaire and was analyzed using SPSS version 23. Mean and standard deviation was calculated for numerical data while frequencies and percentages analyzed for categorical data. Results: A total of 125 faculty members participated in the study, having mean age of 37.8±9.99 years, with the majority affiliated with medical program (78%), working in private institutes (58.4%), and teaching basic sciences (64%). Faculty of both basic and clinical sciences preferred Question and Answer (Zoom) for formative assessment (37.6% and 20.8% respectively). Although most faculty were found to not use any online tool for summative assessment, nonetheless, Socrative was preferred for this purpose (23.2% basic sciences, 12.8% clinical sciences). Almost 68% of the faculty faced difficulties in conducting e-assessments and reported that their issues were not resolved effectively (48.2%). Conclusion: Formative assessment was found to be preferably conducted by the Question-and-Answer feature of Zoom. Even though most of the faculty reported not utilizing any online tool for conducting summative assessment, it was found that quiz-based platforms were preferred.

Authors: Anderson Heather , Jackson Sarah , Bilich Lisa , Hunt Craig , Tipton Elizabeth
Published: May 2023

Purpose: Dental hygienists have the unique opportunity to educate patients on connections between nutrition and oral health. Dental hygiene students are introduced to these concepts but struggle to gain confidence to share this knowledge with patients. This pilot study looked at an educational module on motivational interviewing (MI) and an assessment and counseling tool to build student confidence with nutritional counseling. Methods: Dental hygiene students participated in an educational module to review MI and introduce a nutritional risk assessment and counseling tool. Prior to the module, participants completed a pretest about confidence levels regarding MI and nutritional counseling. After three weeks of clinical practice, participants completed a posttest. Data was compared for quantitative changes and qualitative themes from responses. Results: Twenty-two senior dental hygiene students (n = 22) participated in both the pretest and posttest. There were statistically significant changes in participants’ confidence (p = 0.007) and comfort (p = 0.020) discussing nutrition with patients. Participants struggled to become more confident in MI as demonstrated by no significant change in their feelings surrounding MI (p = 0.150). Students reporting increased nutritional counseling sessions showed improvement in their confidence. Conclusion: Introducing MI with an assessment and counseling tool to aid students can improve confidence with nutritional counseling. This type of education may translate into more chairside discussions about nutrition, improving overall patient care.
Exploring the Transtheoretical Model of Change, Barriers, and Motives to Telemedicine Adoption in Athletic Training
Authors: Griffin Gabrielle , Games Kenneth , Gallegos David , Scarneo-Miller Samantha , Kottak Amanda , Winkelmann Zachary
Published: May 2023

Purpose: The delivery of healthcare services by athletic trainers (ATs) has evolved over the past two years as a result of the COVID-19 pandemic. Previous research has identified an integration of telemedicine as a necessary, urgent replacement for face-to-face patient encounters in athletic training; however, there is a lack of data to support the habitual and intentional change to one’s clinical practice that includes telemedicine. Therefore, the purpose of this study was to identify and analyze ATs respective stages of change related to telemedicine adoption, as well as explore motivating factors and barriers related to the adoption of telemedicine. Methods: We performed a cross-sectional study of 883 credentialed ATs. The survey contained a modified TTM stages of change assessment and 51-item telemedicine barriers and motives tool adapted from previous literature. A logistic regression was performed to assess highest level of education with telemedicine adoption status. Results: Overall, most ATs were categorized in the action, maintenance, and termination stage (n=551/882, 62.4%) for telemedicine adoption. Other participants were categorized in the stages as unaware (n=8, 0.9%), precontemplation (n=82, 9.3%), contemplation (n=78, 8.8%), and preparation (n=164, 18.6%). The logistic regression model was statistically significant (pConclusions: The results of the study suggest that most ATs have recently changed their delivery of healthcare in the last 6+ months and intend to maintain telemedicine use as part of their clinical practice. Additionally, telemedicine success was hampered by a lack of exposure but did feel that telemedicine fills gaps in patient care and addresses improved patient satisfaction. Additionally, increasing an ATs highest level of degree earned was associated with an increased likelihood of being in stage five on the modified-TTM assessment suggesting focused, professional development could sustain telemedicine use in athletic training.
Preparing Faculty Using an Assessment for How Clinical Laboratory Students Learn
Authors: Stewart MaryAnne , Chojnacki Ronette
Published: May 2023

Purpose: Students interpret and learn information in different ways. Whether students develop deep or surface learning depends in large part on the transmission of information from their educator, which activates their domains of learning. Knowing students’ learning styles as either visual, auditory, psychomotor, or mixed, professors can develop teaching resources that benefit the learning diversity of their students by using different instructional delivery methods. This study examines survey results for how students learn best to enhance the student experience within the Clinical Laboratory Science (CLS) program at a university in Detroit, MI, USA. Method: To determine the resources needed to enhance learning for students and to prepare faculty, the cognitive learning styles of students within the last four cohorts of the CLS program were examined. To obtain this data, CLS students, from the 2018-2021 cohorts, participated in an online survey to discuss which cognitive learning styles they identified with based on the survey questions. Results: The majority of students did not just identify with one learning style. However, when presented with two or more learning styles, their retention of the material and experience was enhanced. Conclusion: Creating teaching resources for educators that revolve around multiple learning styles is necessary. Once established, the use of these resources can help enhance learning retention and thus encourage faculty members to thrive within the Clinical Laboratory Science program.

Authors: Vatwani Archana , Morris Melissa , Hill Cheryl , Fernandez-Fernandez Alicia
Published: May 2023

Purpose: The purpose of this study was to determine whether or not training with a computerized stethoscope could impact Doctor of Physical Therapy (DPT) student cardiopulmonary assessment knowledge and confidence. Methods: Eighty-seven (87) DPT students in years 2 (DPT2s, n=39) and 3 (DPT3s, n=48) participated after previously completing a cardiopulmonary course. All subjects took a baseline test and confidence survey for cardiopulmonary skills. Two weeks later, DPT2s attended a 1-hour lab session with simulation stethoscopes and did a post-test and survey. Test scores and confidence data were compared within DPT2s, and for DPT2s vs DPT3s. Results: After training, DPT2 test scores increased significantly (p=0.005, effect size r=0.32). DPT2s also reported significant increases in confidence, with moderate effect sizes, in the following areas: respiratory physical assessment (p=0.001, r=0.37); assessing PT effectiveness for respiratory disease (p = 0.002, r=0.35); cardiovascular physical assessment (p=0.006, r=0.31); and assessing PT effectiveness for cardiovascular disease (p=0.004, r=0.32). The item “assessing PT effectiveness for most disease states” improved but did not reach statistical significance (p=0.058). DPT2s and DPT3s scored similarly in the pre-test (p=0.511), but DPT2s post-test scores were significantly better than DPT3 pre-test scores (p=0.001, r=0.33). Baseline DPT2 and DPT3 confidence scores were not significantly different, but overall DPT2 confidence post scores were significantly higher than the DPT3 baseline. Conclusions: A one-hour lab session utilizing simulated stethoscopes resulted in increased cardiorespiratory assessment knowledge and confidence. Simulated stethoscopes may be a useful didactic supplement to a cardiorespiratory curriculum.

Authors: Friary Philippa , Purdy Suzanne , McAllister Lindy , Barrow Mark , Martin Rachelle
Published: May 2023

Introduction: All healthcare workers are responsible for patient safety and quality improvement and need to “speak up” to communicate issues. As healthcare systems strain under the impact of reduced staffing and workloads increase, allied health new graduates are feeling under pressure and unsupported. Understanding their experiences of speaking up as they transition into the workforce will identify what support they require to fulfil their patient safety and quality improvement responsibilities. Method: An exploratory study was conducted to investigate how new graduates in allied health speak up. Informed by a realist theoretical position, this study was interested in what contexts and resources support new graduates to speak up or not. Two different focus groups with allied health new graduates were used to collect data. Reflexive thematic analysis was employed to draw out key themes and sub-themes. Results: Three main themes were generated –advocacy drives speaking up, scaffolding, and transition impact. Further analysis identified context-mechanism-outcome configurations which were then developed into an initial programme theory. Conclusion: Further in-depth exploration of speaking up behaviour with allied health new graduates will inform leaders within education and workplace settings about ways to develop confident and competent professionals who can speak up for patient safety and quality improvement.

The current era of the industrial revolution 4.0, has a very varied influence on various fields, one of which is the industrial sector, with the growing automation of machines and robots, coupled with intense job competition, every worker must prepare for the possibilities that will occur. in the future, humans must begin to be aware of the rapid development of current technology, and see several possibilities that will occur, later robots may affect human employment, starting from job competition, to jobs being taken over by robots, this is will cause anxiety for workers or actors in the industrial sector. Competition in the world of work today does not only involve humans but is a result of current technological developments, resulting in robots being involved and starting to enter the scope of human work competition. With the emergence of this phenomenon, humans are required to improve their skills and abilities to be able to keep up with the robots when there is competition later. The method used in this study included multiple linear regression methods with a sample of 50 informants using the formula Slovin’s study aims to find out whether these possibilities will occur in the future, and then whether there is an influence from robots and job competition on the future of workers. The results obtained from this study indicate that the influence of robots and job competition has a positive and significant impact on the future of workers and to compensate for robots so that they do not dominate human jobs, these workers should continue to improve their skills, knowledge, and skills.

ENGLISH IDIOMS FROM THE PERSPECTIVE OF MODAL MEANING
Authors: Hovhannisyan Anahit
Published: May 2023

Being a multifaceted unit idioms can be studied from five angles: meaning, function, style, emotiveness and contrastive analysis. The merit of this paper lies in the fact that it attempts to analyze the evaluative functions of English idioms. The analysis is performed within the functional framework of evaluative thesis to establish evaluative semantics of idioms. Idioms operate as encoded resources for amplifying attitudinal meanings to the entities and phenomena they describe. They serve to entail multiple modal meanings intensifying the evaluative force in the text. The values are further divided according to whether the value which entails the intensification is positive, negative or dual. A special category of positive values concerns the use of positive idioms amplifying the negative attitudinal force.
GENDER DIFFERENCES IN VERBAL AND NONVERBAL AGGRESSION
Authors: Knyazyan Anna , Marabyan Liza
Published: May 2023

Gender differences permeate every aspect of human personality and appearance, and dictate how men and women should act, think and behave. Gender embodies a pattern of relations that evolves over time to define male and female, masculinity and femininity, concurrently structuring and regulating people’s relation to society. Gender decides what is expected, permitted and valued in a woman or a man in a given context. This paper discusses male and female aggression in political debates with a special focus on the recent debate held on 9th September 2021 in Canada. The analyses carried out through the methods of content, discourse and pragmalinguistic analyses, show that aggression is frequently categorized as a social behavior, and thus falls within a set of criteria depending on the roles that people occupy. In the world today, there is an increase in the use of communicative aggression, both verbal and non-verbal in the political arena. Aggression is widely applied in political communication where the main purpose is to fight the opponent and get the attention of the audience and voters. Male politicians are expected to be verbally and non-verbally more aggressive than women while female politicians perceived as less aggressive and considered to be better performers. However, this assumption remains an area of contention.
Research of influence of operational factors on parameters fuel delivery accumulator system CR engines RT-FLEX
Authors: Polovinka E. , Tabulinskiy I.
Published: May 2023

The results of a computational study of the influence of operational factors on the fuel supply process by the accumulator system CR of RT-flex engines are presented. In the model used in the study of fuel supply in the accumulator system processes that occur in all its essential elements are described. As an accumulator, a constant pressure source is considered. The most detailed analysis is the operation of the injection control unit that determines the processes in the high-pressure system. Carefully presented nozzles, the elements of which are fully consistent with the real design. A change in the basic characteristics of injection with variable values of the temperature of heating the fuel, its viscosity, pressure in the accumulator and the pressure of the nozzle needle lift is considered. The most significant effect is the viscosity and pressure in the accumulator. An increase in viscosity (lowering the heating temperature) leads to a significant decrease in the cyclic supply of fuel and a decrease in the stroke of the metering piston with constant fuel supply phases. The cycle delivery increases with temperature from 500 C to 90-1100 C from 0,013 to 0,022 kg – 1,69 times. Obviously, the determining factor in this dependence is the movement metering piston injection control unit. This indicator changes in a close way, increasing in the same range from 7.4 to 10.5-10.8 mm. Additional information about the movement of the QP is the speed of its movement. In the direct (working, injection) stroke, it increases with increasing temperature in the above range from 0,135 to 0,244 m / s. As for the fuel pressure in the nozzle, then the influence of temperature is small. It decreases from 610 to 600 bar − less than 2 % (in the ratio of 1,016). This pattern indicates the decisive influence of the hydraulic resistance of the elements of the high pressure path on the pressure in the nozzle. In a similar way, the injection parameters change with decreasing pressure in the accumulator. One of the operational parameters of the fuel supply system is the liftingpressure of the nozzle, which depends on the force from the spring. To assess the influence of the pressure of the nozzle lift, the injection process was simulated at various spring tightening pressures. The range of variation of was 300-450 bar with a nominal value of 375 bar. No noticeable effect was on injection characteristics. The change in the cyclic delivery does not go beyond 3,2 %; the difference in the path of the QP for the boundaries of the range is 2,2 %, and the velocity of the QP remains within 1,8 %. The pressure in the nozzle channel remains unchanged.

Thyroid Isthmus Agenesis: A Rare Phenomenon
Authors: Hivre Dr. Mangesh ,   Assistant Professor, Department of General Surgery MGIMS Sewagram, wardha.
Published: May 2023

The thyroid gland is composed of two lobes connected by an isthmus that traverses the midline of the upper trachea between the second and third tracheal rings. The most common manifestation of dysgenesis of the thyroid gland is hemi agenesis or ectopic thyroid gland tissue. Specifically, the incidence rate of agenesis of the thyroid isthmus ranges between 0.5 and 10%. Remember that the identification of agenesis of the isthmus and other thyroid anomalies during preoperative evaluation of patients scheduled for thyroid surgery would significantly contribute to safer surgical procedures and fewer complications. We present a patient with an enlarged right thyroid nodule on USG who was scheduled for a right hemithyroidectomy but was ultimately diagnosed intraoperatively with thyroid isthmus agenesis.

Most of the pediatric surgical conditions or major congenital malformations are diagnosed on spot or with simple radiological imaging just like Tracheoesophageal Fistula (TEF), e.g., Inability to pass NG tube with coiling of NG tube on chest X-ray. But a few of them are still challenging to diagnose, just like ‘H’ type TEF because of delayed presentation as well as absent classical symptoms. (1) And even in today’s era where radiological accuracy has reached to a new level, this diagnosis is missed many times and only confirmed on table. Here we are reporting a case of ‘H’ type TEF, a 17 days old male child, whom we diagnosed on single attempt with virtual bronchoscopy.

Substituição da nutrição amoniacal pela nítrica para plantas de arroz e feijão
Authors:   , Silva Policarpo Aguiar da
Published: May 2023

O nitrogênio é o nutriente demandado em maior quantidade pela maioria das culturas cultivadas, sendo absorvido principalmente nas formas amoniacal e nítrica. A ureia (Ure) é o principal fertilizante nitrogenado comercializada no Brasil, porém o seu manejo inadequado pode proporcionar perdas expressivas de Nitrogênio(N). Além disso, alto consumo de energia na sua produção tem deixado sua aquisição cada vez mais difícil. Devido a suspenção das atividades da Petrobras em suas unidades de produção de Ureia, somado ao crescente uso de outros fertilizantes nitrogenados, buscou-se avaliar fertilizantes amoniacais e nítricos para as culturas de arroz e feijão, a fim de avaliar se é recomendável ou não a substituição da Ureia por fontes nítricas. No experimento foram avaliados a Ure, o sulfato de amônio (SAm), o nitrato de amônio (NAm) e o nitrato de cálcio (NCa). Também foram cultivados vasos com plantas de ambas as culturas sem aplicação de nitrogênio. Foram utilizados três solos: um arenoso (Ar), um argiloso com baixo teor de matéria orgânica (AGb) e outro argiloso com maior teor de matéria orgânica (AGa). As plantas foram cultivadas por 45 dias. Para o arroz avaliaram-se a produção de matéria seca (pMS), o conteúdo de nitrogênio na parte aérea (cN), a taxa de recuperação aparente de N (trN) e o remanescente de N-NH 4+ e N-NO 3- no solo. Todos os fertilizantes se mostraram eficientes para propiciar aumento da pMS, da mesma forma que proporcionaram ganhos no cN e ainda, nenhuma deles promoveu ganho significativo de N remanescente nos solos. Para o feijoeiro avaliou-se a produção de matéria seca na parte aérea (pMSpv) e das vagens (pMSva), a percentagem de matéria seca na vagem (pcMSva), o conteúdo de N na parte aérea (cNpv), o conteúdo de N nas vagens (cNva), o conteúdo de N total (cNT), a percentagem do conteúdo de N nas vagens (pcNva), o número de vagens (nV), a taxa de recuperação aparente de N (trN) e o remanescente de N-NH 4+ e N-NO 3- no solo. Somente nos solos Ar e AGb observaram- se ganhos na pMSpv com a adubação dos solos, o mesmo observa-se para cN nas plantas. O número de vagens mostrou-se independente da condição de fertilidade do solo, e o remanescente de N no solo não se alterou para nenhuma das fontes utilizadas. Concluiu-se assim, que a substituição da ureia por fontes nítricas mostrou- se viável, sem prejuízos de produtividade. Palavra-chave: Nitrogênio. Nitrato. Amônio. Nítrico.

The Construction Blockchain Consortium (CBC) was established to develop knowledge transfer, arrange commercial and academic presentations, assess and test commercial services and technology, conduct research, and drive policy, regulation and understanding of the consequences of Blockchain and other emerging technologies in the Built Environment. We also establish open-source projects and encourage application developers to build proprietary technology and services for sustainable construction solutions. In this first document of a series of white papers, we elaborate on the impact of blockchain in construction financing & procurement. Originally, we envisioned one document to cover the domains of financing and procurement. However, it soon transpired that the complexities of this intersection of multidisciplinary knowledge calls for topic analysis in order to retain the definition required to inform prospective technological applications. Therefore, here we review current developments of blockchain technology relevant for construction smart contracts and assess its impact in the construction cash flow models and some of its procurement devices. This document aims to gather evidence with a view to shaping future policy and regulation in collaboration with the British Parliament.

There seem to be a low attention towards the use of computer as a medium of instruction to optimize education especially in primary schools. This paper, through a quasi-experiment examined the effects of Computer-Assisted Instruction (CAI) on pupils’ performance in Quantitative and Verbal Reasoning. The population for the study comprised all the public primary school pupils in Lagos State. The target population consists of all the primary five pupils in Lagos State public primary schools. The study purposively sampled 2 Government owned schools based on the availability of computer facility in them and randomly sampled 154 primary school pupils. The research instrument that was used for the study was a researcher-made model. The data generated were analyzed using percentages while the hypotheses formulated in this study were tested using Analysis of Covariance (ANCOVA) at 0.05 alpha level of significance. The findings show that CAI has a significant positive effect on pupils’ performance in Quantitative and Verbal Reasoning. Based on the tested hypotheses, it is hereby recommended that government should provide CAI devices to all public primary schools in Lagos State and proffer the means of using the CAI devices (electricity).

Published: May 2023

The research examined the challenges that rural school heads faced in implementing the new curriculum in Zimbabwe. Six primary school heads participated in this study. Curriculum changes were initiated as a key focus to restructuring the educational system with a strong emphasis placed on its implementation. The changes were intended to improve the quality of education for the benefit of learners. Qualitative and quantitative research approaches were employed, and the case study research design was used. The population comprised of twenty-eight primary schools in Mutoko district and from these six primary schools were purposefully selected. Interview guides, observation guides and document analysis schedules were used in this research study. The use of the three methods of gathering data was meant to increase the validity and reliability of the findings. The data from interviews were transcribed word for word and that from observations and document analysis were coded and then classified into different categories of themes. Findings revealed that teacher expertise, inadequate resource materials and lack of parental involvement in school activities were challenges that school heads faced in implementing the new curriculum. It was found out that Ministry involvement was greatly needed to equip schools with the requisite teaching staff and adequate resources for effective implementation of the new curriculum to take place.

"Crowded pedestrian detection" is a hot topic in the field of pedestrian detection. To address the issue of missed targets and small pedestrians in crowded scenes, an improved DETR object detection algorithm called DETR-crowd is proposed. The attention model DETR is used as the baseline model to complete object detection in the absence of partial features in crowded pedestrian scenes. The deformable attention encoder is introduced to effectively utilize multi-scale feature maps containing a large amount of small target information to improve the detection accuracy of small pedestrians. To enhance the efficiency of important feature extraction and refinement, the improved EfficientNet backbone network fused with a channel spatial attention module is used for feature extraction. To address the issue of low training efficiency of models that use attention detection modules, Smooth-L1 and GIOU are combined as the loss function during training, allowing the model to converge to higher precision. Experimental results on the Wider-Person crowded pedestrian detection dataset show that the proposed algorithm leads YOLO-X by 0.039 in AP50 accuracy and YOLO-V5 by 0.015 in AP50 accuracy. The proposed algorithm can be effectively applied to crowded pedestrian detection tasks.

Authors: Salem AL-AQILI Fatma
Published: May 2023

In the year 631 BC, a Greek city was founded in the eastern part of Libya, known as Cyrene, by colonists from the Greek island of Thera. Macomades Euphrantas, Agaila to the West, is called the province of Cyrene, while the area to the west was under the influence of the Carthaginians. And since the Greek and Roman literary sources have singled out talk about this region since its foundation, the distinction of this region with its medicinal plants was praised by ancient poets and writers, such as Homer, Herodotus, Pandaros, Theophrastus and many others. Plants that gained great fame in the ancient world at the time. In view of the inability to list all the medicinal plants for which the region was famous, we will address some of them through what was reported by the literary sources, where we specify in the first requirement the extension of the vegetation cover in the region and then in the second requirement the names of medicinal plants, their characteristics and areas of spread, and then we will address in the third requirement their medicinal and therapeutic properties And let us conclude this research with a brief conclusion of all that we have come to

Published: May 2023

The use of advanced information technology contributed to the production of huge data. This made it difficult to analyze and determine its ability to influence the decision-maker. Sustainability reports represent an integrated set of narrative non-financial information, and that the problem of these reports is not governed by unified standards and there are no agreed measurement methods. Rather, the design of these reports is left to the responsibility of managing economic units. Therefore, the task of the auditor is difficult in light of the diversity of these reports and the lack of sustainability audit requirements in local environment. The study aimed to clarify the concept of big data technology and its types and uses of each type. Also, to show the impact of this technology on data production. In addition, study the impact of this big data with regard to auditing sustainability reports The most important conclusions are that the quality of the audit depends on the quality and quantity of data and information provided by the economic unit administration in the sustainability reports. The greater the amount of data, the greater the audit risks that reduce the quality of the audit.
