Corona-bedingte Finanzhilfen des Bundes zur Entlastung der kommunalen Haushalte, Eine finanzwissenschaftliche Betrachtung
Authors: Döring Thomas
Published: April 2021

Durch die Corona-Krise haben die Kommunen nicht geplante zusätzliche Ausgaben und gleichzeitig hohe Ausfälle bei den Steuereinnahmen. Im Gegensatz zu Bund und Ländern sind die Kommunen haushaltsrechtlich deutlich stärker beschränkt, wenn es um die Kompensation von Einnahmeausfällen geht. Daher droht vielen Kommunen kurzfristig eine finanzielle Notlage. Dies zu verhindern ist in erster Linie die Verantwortung der Länder. Aufgrund des historischen Ausmaßes der Krise kann auch der Bund zeitlich begrenzt zur Stabilisierung der Kommunalfinanzen beitragen. Dieser Beitrag ist eine überarbeitete Fassung einer Stellungnahme des Autors als Sachverständiger im Rahmen einer öffentlichen Anhörung des Haushaltsausschusses des Deutschen Bundestages am 7. September 2020 und konzentriert sich auf eine ökonomische Bewertung der direkten Finanzhilfen des Bundes für die Kommunen.
RANGE AND RADIAL VELOCITY MEASUREMENT AMBIGUITY ELIMINATION WITH TRAINS OF MULTICOMPONENT SIGNALS
Authors: Buhaiov M. V. , Samoilyk S. P.
Published: April 2021

When designing pulse-Doppler radar, one of the key points is the choice of the pulse repetition period, which determines the boundaries of unambiguous measurement of range and radial velocity and creates contradictions in the measurement of these values. This contradiction is especially acute in the analysis of signals reflected from the propellers and turbines of aircraft. The main approaches to solving the problem of expanding the boundaries of unambiguous measurement of range and radial velocity is the use of variable pulse repetition period and the creation of signal ensembles to separate them by shape. Generation of an ensemble of sounding signals for a pulsed radar must be carried out taking into account both cross-correlation and auto-correlation properties. An approach to the generation of multicomponent signal trains with the possibility of pulse separation inside the train is proposed. Each of the pulses in the train is formed by adding a number of chirp signals, which differ in the values of amplitude and frequency deviation. As the frequency deviation increases, the amplitude of the component decreases. Reducing the cross-correlation coefficient of multicomponent signals from the formed ensemble can be achieved by increasing the number of components of each signal. The size of the signal ensemble, which can be formed on the basis of multicomponent chirp signals, depends on the requirements for the cross-correlation coefficient and auto-correlation function of the signals. It is shown that in order to expand the limits of coordinate measurement at a fixed wavelength, it is necessary to increase the number of pulses in the train. The results of the research demonstrate the potential possibility of using the proposed multicomponent chirp signal to form train of pulses with its subsequent separation.
AUTOMATIC TRAIN DOOR PORTAL SYSTEM USING REGULATED STRAIGHT MOTION FORMULAS
Authors: Sri Winar
Published: April 2021

The train station is an important facility. However, the services provided to train passengers are still not optimal. There are still several weaknesses, including the arrival and departure processes of trains that still rely on telephone communication with other station staff. Notification of train arrival will be sent by telephone by the officer at the previous station to the destination station. On receiving notification of arrival, station staff will close the train portal. This process can have a weakness, and namely, if there is the officers' negligence, it can cause an accident. This is due to the absence of an automatic operating system on the railroad crossing portals. Because the manual system must use human labour or operators to operate and open the railroad crossing portals, so that operator error or failure of manual operation of the portal can increase the likelihood of a train accident occurring at the crossing portal, the above problems can be overcome by implementing an automatic portal closure system. With an automatic portal system, the portal will automatically close if a train passes through the crossing.
A Frequency and Polarization Reconfigurable Dual-Patch Microstrip A Frequency and Polarization Reconfigurable Dual-Patch Microstrip
Authors: Bui Cong , Dang Thanh , Doan Minh , Nguyen Truong
Published: April 2021

This paper proposes a reconfigurable microstrip patch antenna design for wireless ISM band applications. The antenna simultaneously uses PIN Diodes to switch between linear and circular polarization at 2.45 GHz and uses Varactor Diode to continuously tune the
operating frequency from 1.73 GHz to 2.45 GHz. The antenna performance is characterized as a combination of ON/OFF state of PIN Diode and a bias voltage of Varactor Diode varying from 0.8V to 10V. A good agreement between simulation and measurement is
obtained which validates the proposed method. The proposed frequency/polarization reconfigurable antenna is promising for various applications in wireless ISM band such as DCS (1710 – 1880 MHz), PCS (1850 – 1990 MHz), GSM 1800, GSM 1900, UMTS (1920 – 2170 MHz) and WiFi/Bluetooth (2.4 – 2.5 GHz).

Authors: Yu Quanyi , Liu Wei , Yang Kaiyu , Ma Xilai , Wang Tianhao
Published: April 2021

The degree adaptive stochastic response surface method is applied to analyze statistically the crosstalk in multiconductor transmission lines (MTLs). The coefficient of polynomial chaos expansion (PCE) is obtained based on the least angle regression. The truncation degree of PCE is iterated using the degree adaptive truncation algorithm, and the optimal proxy model of the crosstalk of the original MTLs that satisfies the actual error requirements is calculated. The statistical properties of crosstalk in MTLs (such as mean, standard deviation, skewness, kurtosis, and probability density distribution) are obtained. The failure probability of the electromagnetic compatibility in the MTLs system is considered. The global sensitivity indices of crosstalk-related factors are analyzed. Finally, the proposed method is proved to be effective compared with the conventional Monte Carlo method. The uncertainty quantification of crosstalk in MTLs can be calculated efficiently and accurately.
Analysis of EMI from Pantograph-catenary Arc on Speed Sensor Based on the High-speed Train Model
Authors: Tang Yutao , Zhu Feng , Chen Yingying
Published: April 2021

There will be the pantograph-catenary arc (PCA) when the pantograph of a high-speed train is separated from the power supply line, and the electromagnetic interference (EMI) caused by the PCA can affect speed sensors of the train. To study the influence of the PCA, firstly, the traction control unit (TCU) speed sensor of the high-speed train is researched. The result shows both overvoltage and electromagnetic radiation (EMR) generated by the PCA can influence the signal of speed sensor. Secondly, the composite model of the train is established. Then, the interference of the PCA on the TCU speed sensor is verified. The results of practical measurements show the PCA causes a maximum overvoltage of 680 V on train body (TB) and increases the magnetic field around TB to a maximum of 58 dBµA/m. This is the reason of sensor malfunction, which is consistent with the theoretical and simulation results. Finally, the methods to reduce the EMI of the PCA are proposed.
Studying and Analysis of a Novel RK-Sinc Scheme
Authors: Zhu Min
Published: April 2021

In this paper, a novel high-order method, Runge-Kutta Sinc (RK-Sinc), is proposed. The RK-Sinc scheme employs the strong stability preserving Runge-Kutta (SSP-RK) algorithm to substitute time derivative and the Sinc function to replace spatial derivates. The computational efficiency, numerical dispersion and convergence of the RK-Sinc algorithm are addressed. The proposed method presents the better numerical dispersion and the faster convergence rate both in time and space domain. It is found that the computational
memory of the RK-Sinc is more than two times of the FDTD for the same stencil size. Compared with the conventional FDTD, the new scheme provides more accuracy and great potential in computational electromagnetic field.
Vulnerability to rumours during the COVID-19 pandemic in Singapore
Authors: Long Victoria JE , Koh Wei Shien , Saw Young Ern , Liu Jean CJ
Published: April 2021

Introduction: Amid the COVID-19 pandemic, many rumours have emerged. Given prior research
linking rumour exposure to mental well-being, we conducted a nationwide survey to document the base
rate of rumour exposure and factors associated with rumour vulnerability.
Methods: Between March and July 2020, 1,237 participants were surveyed on 5 widely disseminated
COVID-19 rumours (drinking water frequently could be preventive, eating garlic could be preventive, the
outbreak arose because of bat soup consumption, the virus was created in an American lab, and the virus
was created in a Chinese lab). For each rumour, participants reported whether they had heard, shared or
believed each rumour.
Results: Although most participants had been exposed to COVID-19 rumours, few shared or believed
these. Sharing behaviours sometimes occurred in the absence of belief; however, education emerged as a
protective factor for both sharing and belief.
Conclusion: Our results suggest that campaigns targeting skills associated with higher education
(e.g. epistemology) may prove more effective than counter-rumour messages.

Authors: Mohamed Lobna K. , Dorgham Shereen R. , Eid Walaa M.
Published: April 2021

Context: Professionalism is an essential ingredient in the nursing profession that begins during the foundational educational program when the student nurses learn the knowledge, skills, and attitudes and continue during their practices in the real world.

Aim: This research aimed to assess the main attributes of professionalism among undergraduates nursing students and nurses.

Methods: This study utilized a descriptive comparative correlational design. The current study was conducted in the faculty of nursing, as well as in Intensive Care Units, Neonatal Intensive Care Units, Cardiac Care Units, and Neurology Intensive Care Units at Tanta University Hospital. Subjects. The sample consisted of (897) nursing students and (149) nurses. The data collection’s tool was the nursing professionalism attributes' questionnaire that was developed by the authors. It contains three dimensions, including; professional identity (12 statements), professional ethics (12 statements), and professional behaviors (16 statements).

Results: This study suggested that the undergraduate nursing students perceived the high mean score in all professionalism attributes more than the practicing nurses did.

Conclusion: This study concluded that the development of professionalism in nursing is an essential feature of the nursing profession and practice. The nurse students were high in areas of patients and colleagues’ rights, obeying orders, commitment and collaboration, physical appearance, continuing education, and caring of the patient. While the nurses had very low scores in membership in the nursing association, autonomy, and research areas, this study recommended the encouragement of nurses and students' participation in scientific research activities, including; membership in professional organizations or associations, attending nursing conferences/workshops/symposium as a producer or consumer, and fellowship.

Published: April 2021

Background: Successful plans in disaster and epidemics management depend on the feedback response and the assessment of knowledge, attitudes, and practices among the target population. This study aims to assess the knowledge, attitude, and practice towards COVID-19 among Libyan people. 

Methods: A cross-sectional web-based survey designed to assess the knowledge, attitude, and practice towards COVID-19 among the Libyan people from 13-20 October 2020. A self-administered questionnaire was recruited to collect the data of 287 participants. SPSS version 16.0 was used to analyze the data using univariate and multivariable regression data analyses.

Results: More than half of respondents were males (53.7%), married (61.3%), aged less than 45 years old, highly educated (46.3%), employed (44.6%), urban resident(79.8%), experience good or very good health (71.1%) and earned more than USD 200 monthly (84.3.%). The participants showed a high rate of good knowledge (81.0%), attitude (71.1%), and practice (83.7%) towards COVID-19, respectively. Regression analysis showed that married (P=0.056), female (P=0.037), living in the urban regions (P<0.001) with good income of more than USD 2020 (P=0.001) were significantly associated with upper knowledge score. Females (P=0.040) were more significantly associated with positive attitude scores than males. Regarding practice score, married (P=0.001), females (P=0.059) had better practice, but poor-rated health status (P=0.018) was significantly associated with the weak practice.

Conclusion: The distinction of urban regions with good knowledge, optimistic attitudes, and acceptable practices towards COVID-19 determines the government's action compass towards more interest in supporting males, unhealthy, and those living in the rural areas with accurate and timely knowledge.
Is it Possible to Bring 4 Pregnancies to Term with Obstructive HCM without Maternal or Fetal Complications? (A Case Report and Literature Review)
Authors:   Department of Cardiology B, IBN SINA Hospital Center, Mohammed V University, Rabat, Morocco, Oussou Yousra
Published: April 2021

Obstructive hypertrophic cardiomyopathy (HCM) during pregnancy is associated with significant maternal and perinatal morbidity. Physiological changes during pregnancy can induce complications: sudden death, heart failure and arrhythmia involving the maternal and fetal prognosis. Women with HCM generally tolerate pregnancy well. The risk is however higher in women who are symptomatic before pregnancy or in those with severe left ventricular outflow tract obstruction. The incidence of arrhythmias does not appear to be increased during pregnancy and maternal mortality is low. Prior to conception, women with HCM should have a risk assessment as well as genetic counseling. A vaginal delivery with regional anesthesia is usually appropriate. Women should be managed by a specialist multidisciplinary team.

La carga de ambos fue equiparada con relación a la duración de la parte central de las sesiones. Todos los sujetos fueron evaluados con tests de fuerza máxima (Back Squat, Bench Press y Dead Lift), fuerza resistencia (Squat y Push-ups) y fuerza explosiva (Squat Jump y Abalakov) pre y post intervención. Se verificaron mejoras en ambos grupos en todas las variables analizadas (p < 0,05), pero no se hallaron diferencias entre grupos como consecuencia de los distintos programas de entrenamiento. Se concluye que ambos programas de entrenamiento son similarmente efectivas para desarrollar la fuerza máxima, la fuerza explosiva y la fuerza resistencia en adultos entrenados.
Abstract: Muscular strength development in its different expressions forms is relevant for both sport performance and health. The purpose of the present study was to determine the effects of CrossFit training in comparison with traditional resistance training on different expressions of strength. Fourteen adults of both sexes, with strength training experience, were randomly divided into two groups to perform 8 weeks of training: one group (CF; age: 24.9 ± 1.6yrs) performed CrossFit and the other group (ET; age: 28.7 ± 4.6yrs) performed traditional strength training. The training load of both programs was equated in relation to the duration of the main part of the sessions. All subjects were tested for maximal strength (Back Squat, Bench Press and Dead Lift), endurance strength (Squat and Push-ups) and explosive strength (Squat Jump and Abalakov) before and after the intervention. Significant improvements were verified in both groups post intervention for all the variables analyzed (p <0.05), but no significant differences were found between groups as a consequence of the different training programs. It is concluded that both training modalities are similarly effective in developing maximal strength, explosive strength and endurance strength in trained adults.

Published: April 2021

Several governments around the world have tried strategies based primarily on financial education programs to improve the financial literacy of their citizens. In this study, we discuss a new strategy that involves using knowledge transfer activities carried out by intermediary agents, called financial knowledge brokers, to achieve significant improvement in financial literacy. Thus, the aim of this paper is to test the impact of the five activities of financial knowledge brokers (i.e., financial knowledge acquisition, financial knowledge integration, financial knowledge adaptation, financial knowledge dissemination, and creation of links) on financial literacy. For this, we built a database from a questionnaire carried out to nearly 103 financial advisers during the period June 2015 to June 2017. Overall, the results of Structural equation Modeling (SEM) technique showed that the financial knowledge brokerage activities (four of the five activities) have a positive impact on improving financial literacy as well as on its four dimensions, namely financial attitude, financial behavior, basic financial knowledge, and advanced financial knowledge.

Este artigo visa a discutir relatos de experiência de dez licenciandos de Letras de uma universidade pública para se compreender os significados que (re)construíram com sua participação no Programa Institucional de Bolsas de Iniciação à Docência (PIBID), sub-projeto Inglês. Desenvolveu-se, portanto, uma pesquisa qualitativa (Flick, 2009) que, após contextualizar o ensino de língua inglesa no Brasil (Celani, 2010; Leffa, 2016; Szundy, 2017), apoia-se teoricamente em elaborações recentes sobre a formação do professores de línguas (Celani, 2016; Silvestre, 2017) e o papel de narrativas para deflagrar reflexões durante nesse processo (Barcelos; Ruohotie, 2018; Mello, 2020), bem como sobre as identidades do docente de línguas (Barkhuizen,2017; Freitas; Velasques,2018; Reichmann; Romero, 2019). Os resultados da pesquisa confirmam o potencial do Programa em intervir para transformações identitárias, uma vez que os dizeres dos participantes colaboradores puderam revelar as aprendizagens construídas socialmente com o desenvolvimento dos trabalhos propostos. Essas aprendizagens foram ocasionadas especialmente pelas interações com colegas, alunos da escola pública, com professores e educadores da universidade. Sendo assim, constata-se que o PIBID proporcionou ressignificação da identidade docente dos futuros professores de inglês, o que pode encaminhar mudanças qualitativas na prática de ensino-aprendizagem da escola pública.

Dinamika Kampung Kota Berkelanjutan Di Tengah Pandemi Covid-19
Authors: Nurjani Ni Putu Suda
Published: April 2021

Kampung kota sebagai salah satu wujud permukiman di Indonesia, dimasukkan dalam kategori permukiman kumuh (Slums). Kehidupan perkotaan yang dipandang mampu memberikan harapan penghidupan bagi masyarakat desa, membawa arus bawaan yaitu perpindahan penduduk sehingga ruang publik yang ada di perkotaan menjadi semakin berkurang. Lokalitas yang terkandung pada tatanan kampung akan memberi karakter bagi pembentukan semangat urbanisme baru yang sesuai dengan karakter masyarakat. Perwujudan urbanitas dan ruang kota yang berkelanjutan dapat dicapai dengan rumusan prinsip-prinsip yang telah lama diwariskan oleh nenek moyang bangsa ketika membentuk sebuah kampung tradisional. Namun, di tengah pandemi covid-19 yang melanda dunia, keberadaan kampung kota di Indonesia mengalami gejolak yang cukup besar. Masyarakat urban yang dulu nya membentuk sebuah kampung di daerah perkotaan, kini memilih kembali pulang ke daerah asal akibat minimnya pekerjaan yang tersedia di kota. Banyak pekerja dirumahkan tanpa pesangon, dengan tuntutan hidup yang besar, membuat kaum urban memilih pulang kembali ke kampung halaman. Kawasan permukiman yang sebelumnya tumbuh tidak direncanakan, kini ditinggalkan. Ilegal settlement yang dahulu meresahkan, semenjak pandemi berubah menjadi kampung tidak bertuan. Ketika sebuah permukiman yang awalnya dianggap sebagai sebuah beban dan merusak citra kawasan kini ditinggalkan, apakah kota menjadi lebih baik, apakah kehidupan sosial masyarakat kota menjadi baik atau sebaliknya. Fenomena ini memerlukan sebuah kajian mendalam. Citra buruk kota yang sebelumnya selalu dibebankan pada permukiman kumuh, kini bisa dilihat bagaimana permasalahan agraria yang sebenarnya. Dalam permukiman kumuh tumbuh sistem kekerabatan baru yang saling menguatkan antar orang perantauan, membentuk sebuah ruang publik informal yang mendukung kaum individualistis yang hidup di kota.
The Combined Effect of Strength and Speed Training on Change of Direction Performance in Soccer Players
Authors: CARVAJAL Rafael , SALAZAR Walter
Published: April 2021

Soccer is an intermittent sport where high-intensity actions such as sprints, jumps, and change of direction (COD) can become determining factors of success. Strength and speed are essential physical qualities related to an athlete's COD ability. The influence of strength and speed training on COD performance has been examined in various sports. The purpose of this study was to determine the effect of a combined strength and speed training program on COD performance in high-performance junior soccer players. The study was a randomized crossover trial designed to determine whether there is a difference in the COD test performance after treatment of strength and speed training. Eighteen soccer players were recruited from the same team and randomly assigned to two experimental groups and a control group. The players were evaluated in four various tests, the Illinois Agility Test, 30 meters speed test, 30 meters speed with a change of direction Test and, the 5RM submaximal strength Test. Four 2(Test) x 3(groups) ANOVAs with Tukey posthoc test were performed to detect any statistically significant differences between and within the training groups. An alpha-level of <0.05 was considered to be statistically significant. This study did not find significant improvements in the performance of the studied qualities speed (linear and COD) and, nor an increase in the strength test's performance linked to the treatment used at the end of the six weeks of combined treatment of strength and speed. Strength plus speed training can be used to improve strength during the competitive season.

Conversation Strategies and Communicative Competence
Authors:   University of Liverpool, UK, Jones Christian
Published: April 2021

The book reports on research into teaching conversation strategies as a means of developing communicative competence. The introductory chapter defines key terms and positions this book’s aims and arguments. The next four chapters each describe a different study examining the teaching of conversation strategies in a different way: a learner corpus investigation of strategies used by both learners and users of English as a lingua franca; a materials evaluation study based on the responses of teachers in a variety of contexts; an experimental study in an ESL context, comparing the effects of teaching conversation strategies to a control group receiving no instruction; and finally a qualitative diary and interview study in an EFL context. The author concludes by discussing the implications of these studies for teachers and researchers.
What are conversation strategies and why teach them?
Authors: Jones Christian
Published: April 2021

In this chapter, the author aims to explain the theoretical basis of this book. In doing so, there is a need to look at several key areas. He starts by defining conversation strategies and showing how they differ from and are related to more generalised communication strategies. Next, he defines communicative competence (Hymes, 1972) and shows why this theory should still provide an important basis for developing the teaching of conversation within a communicative teaching framework, whichever precise form that takes. Following this, he explores why we might teach conversation strategies as a means of helping to develop communicative competence. Finally, he gives one brief example of how this might look in the classroom.

Psychiatric patients have got an increased morbidity and mortality to other physical health problem. The most problem they are facing is the lifestyle factors such as the use of substances and the decreased physical activity. These patients are mainly restricted to their home. If mental ill patients do not create any problems to the family members and their neighbouring families, the family members are happy and not so much bother about the patients. And if they are not creating any problems for others, family members are not bothered or motivated to treat the mentally ill patients. Hence the lack of motivation from the other family members results in mentally ill patients showing the symptoms of the high risk of being affected by other health problem. There is the availability of treatment to the mentally ill patient. There was only a little availability of the treatment facilities for the psychiatric patients. So the lack of services available and the most vulnerable nature made them more adherent to the problems. There is a direct relationship between the physical and mental health of the patients. In this study the researcher dealing with only the minor issues such as substance abuse, obesity, hypertension, diabetes along with the mental illness, and it would be a way to understand the problems of these patients. The main aim of the study is to study the problems of mentally ill patients and the objectives are; to study the physical health status of the mentally ill patients; and to study the lifestyle factors such as smoking and alcoholism affected the life of mentally ill. The detail studies of 5o intake patients from the hospital where the psychiatric department exist are taken. The interview schedule is used and more observation and case records were referred to get the history. Secondary data is also considered for the research study.

Hyper IgE Syndrome (HIES) is a rare primary immunodeficiency disease. Most of HIES cases are sporadic. Autosomal dominant HIES is caused by mutation in signal transducer and activator of transcription-3 (STAT-3). A number of mosaicism HIES has been reported that is associated with intermediate phenotype. Autosomal recessive HIES is due to mutation in Dock-8 or cytokinesis-8 and TYK-2 or tyrosine kinase-2. The common manifestations are atopic eczema, staphylococcal dermatitis, cellulitis and folliculitis (cold dermal abscesses that are not warm, painful and without redness), recurrent pneumonia and pulmonary abscesses, osteopenia and recurrent bone fracture. The diagnosis of standard HIES is based on clinica suspicion. There is no specific treatment for HIES. The treatment should be based on the prevention of developing infections. Prophylactic antibiotics such as cotrimoxazole and IVIG are administered. Hematopoietic stem cell transplantation was done for all types of HIES, but there is a little information and experience about the long term results of this therapy.

Infectious diseases are the main causes of morbidity and mortality worldwide. There is increasing concern of indiscriminate use of antibiotics and incidences of multiple antibiotic resistances in human pathogens. The potential of higher plants as source of new drug leads has been demonstrated but is still under explored. In Africa and most developing countries, traditional medicine still forms the backbone of rural medicinal practice. Although a number of American and Asian countries medicinal herbs have been evaluated scientifically and their medicinal properties demonstrated. In Africa, attempts to evaluate medicinal plants in relation to their biological activities and medicinal usefulness are limited. The emergence of antibiotic resistance has led to increased use of herbal medicine as an alternative to combat various ailments. This study aimed at determining the antimicrobial activity of Vernoa hildebrandtii, Acacia stuhlmannii and Moringa oleifera leafy and root bark extracts using disc diffusion technique. Crude extracts were obtained from dried powder by single solvent maceration with ethanol and water. Bioassays were used to evaluate the bioactivity of the extracts against Escherichia coli and Staphylococcus aureas. Antimicrobial activity was determined by measuring the zones of growth inhibition in mm. Moringa aleifera root water extract was the most potent fraction with bioactivity arrange of between 6-32 mm followed by Acacia stuhlmannii root bark water extracts with bioactivity range between 12-31 mm and Moringa oleifera root bark with bioactivity range of between 6-29 mm. Vernoa hildebrandtii leave alcohol and Acacia stuhlmannii Taub root bark- alcohol extract had bioactivity range of between 9-28 and 5-28, respectively. However, Acacia stuhlmannii leaf extracts did not show any antimicrobial activities. The antimicrobial effects of the plant extracts were dose dependent. These findings validate what have been known about Moringa oleifera. They also demonstrate potential biochemical agents in Vernoa hildebrandtii and Acacia stuhlmannii extracts in the management of diarrheagenic microorganisms
