Authors: Mwachugha Alfred Gift , Byiringiro Jean , Ngetha Harrison , Carolus Thomas , Stahl Kathrin
Published: November 2020

A Prandtl probe is one of the standard instruments used for flow characterization in wind tunnel facilities. The convectional fabrication method of this instrument requires skilled artisanship, precision drilling, lathing and soldering of its several parts. This reflects into high costs of production in turn making wind energy studies expensive. With the adoption of additive manufacturing, the tooling costs, skills required and design to manufacture constraints can be addressed. This research presents a Prandtl probe that was designed using NX™ software, fabricated by desktop stereolithography additive manufacturing platform and validated in a wind tunnel for velocity range of 0 m/s to 51 m/s. This research attested the option of fabricating relatively cheap functional Prandtl probe with desktop stereolithography technology which can be used for accurate determination of flow quality in wind tunnels experiments. This provides various learning and research institution in developing countries that have already invested in additive desktop manufacturing technology certainty and a cheaper option to fabricate wind research instruments for use at their laboratories. Moreover, fabrication and validation of a 5-hole Prandtl probe can also be examined.

Authors: Petrov Ivan , Janevski Toni
Published: November 2020

The development of the telecommunication networks observed in present and future time is impressive. Today we witness rapid implementation of 5G networks. We can say that this actually is the moment when (artificial intelligence) AI enters at small door but in the beyond 5G world it is expected to have the prime role in smart operation, management and maintenance of non-software defined networking (SDN), network function virtualization (NFV) and especially at SDN and NFV aware networks. Number of standardization body’s and work groups are focused in a way to create a framework that will define the future use of AI and security standards necessary to exist in order to create health environment for the next generation telecommunication infrastructure. In the wireless world AI/Machine learning (ML) has great potential to shake the way we operate and to become foundation of the transformation that leads to the next industrial revolution. Network virtualization gives flexibility and freedom of the telco operators to choose the hardware and network topology they need for AI/ML platforms and big data sets. 5G and IoT create positive environment for AI and ML development and usage. As the network requirements are developed and the number of the users raises, gains are expected to grow with the number of variables and the interactions among them so it becomes impossible to relay on humans to control the network for increased number of variables and this is why AI with ML and automation become beneficial and necessity to run the future networks. AI generally is defined as capacity of mind or ability to acquire and apply knowledge and skills while ML is defined as learning that does not require explicit programming. Combined usage of AI and ML can optimize almost any component of the wireless network, this does not mean that it should be used everywhere mainly because at the end of the day the cost benefit analysis of its usage must be positive. Smart operation, management and infrastructure maintenance (SOMM) networks are defined as: Intelligent, data driven, integrated and agile. Today AI is introduced but in future it will represent the network engine. It is interesting to mention that network security must be upgraded because the network will provide services for massive number of IoT devices that will have variety of functions and requests. AI/ML can improve the security services and to be used in order to elevate them at advanced level. In this text we focus our attention at AI/ML and security scenarios defined for IoT in 5G environment.

Published: November 2020

This study was conducted to determine the microbiological quality of fresh raw and unwashed leafy and salad vegetables in Dhaka, Bangladesh. Six different types of samples (red amaranth, spinach, carrot, radish, tomato, and cucumber) were collected in pre-sterilized zip-lock bags from various local markets in Dhaka. All samples were transported to the Centre of Excellence for Global Health Research Laboratory of Primeasia University at earliest convenience. Samples were enriched in Nutrient Broth media and were then cultured on selective media for isolation purpose. Serial dilution was performed for the total viable count. Biochemical and carbohydrate profiling was conducted for the presumptive identification of the isolates. Commercial antibiotic discs were used for antibiogram by Kirby-Bauer disc diffusion method on Mueller-Hinton agar medium. The total microbial load ranged from 8x107 to 1.70x108. Total 36 isolates were identified, having 7 differentorganisms. The most predominant organism was Vibrio sp. (23%) followed by Klebsiella sp.(20%), Acinetobacter sp. (19%), Pseudomonas sp. (19%), Salmonella sp. (8%), Moraxella sp.(8%) and Escherichia coli (3%). 11% of the Vibrio sp. isolates were V. cholerae, found from 4 samples. No presence of V. cholerae was observed in the tomatosamples. E. coli was observed only in Carrot sample. Antibiotics from 7 different groups were tested against the organisms among which Imipenem showed the highest sensitivity (86%). Following Ceftriaxone (100%), Nitrofurantoin (94%), Erythromycin (89%) and Amoxicillin (83%) had the highest resistance against the isolated organisms. Moreover, most of the isolates showed a multi-drug resistance pattern where they were resistant to at least four drugs. Prevalence of pathogenic bacteria in raw unwashed vegetables can cause potential adverse health effects and therefore the consumers need to be conscious about the matter.

Published: November 2020

Objective: To analyze the frequency, clinical and therapeutic aspects of paratesticular tumors in the urology department of the Ibn Rochd UHC.

Patients and methods: Retrospective study of 5 patients with partesticular tumors treated in the urology department of Ibn Rochd UHC between January 2014 and December 2019. The parameters studied were age, circumstances of discovery, histological type of the tumor and the treatment performed.

Results: Five paratesticular tumors were recorded among all patients admitted for a tumor of the urogenital system, representing a prevalence of 0.52%. The mean age of onset was 27 years (range 17—65 years). The circumstances of discovery were a scrotal mass in 60% of the cases, that is to say three patients and an inguinoscrotal mass in two patients. Several histological types of tumors have been recorded: three cases of rhabdomyosarcomas, either 60%, one case of sarcoma, either 20%, and one case of fibroma. The modalities of the surgical treatment carried out were enlarged orchidectomy by upper inguinal approach with lymph node dissection in two patients, enlarged orchidectomy by upper inguinal approach without lymph node dissection in two cases and one case of tumerectomy.

Conclusion: Paratesticular tumors are rare. They are found mainly in young adults. The clinical presentation is variable and the diagnosis often late. Management is multidisciplinary but remains essentially surgical. Our study illustrates the great histopathological variability of paratesticular tumors.
A Rare Case of a Metastatic Basal Cell Carcinoma
Authors: Chaudhry Hiba , Doumpiotis Dimitrios
Published: November 2020

Background: Basal cell carcinomas are malignant slow-growing neoplasms of the epidermal layer of the skin. They are the most common form of skin cancer, accounting for 80% of non-melanoma skin cancers. Metastasis is rare with an incidence rate of 0.0028 to 0.55%. We report a case of an 83 year old male presenting with basal cell carcinoma (BCC) of the right cheek. The tumour was completely excised with close margins. The patient was closely monitored clinically and on follow-up, a mass in the region of the right parotid was identified. Excision of the tail of the right parotid identified a tumour with similar subtype to the primary tumour excised from the cheek confirming diagnosis of metastatic BCC.

Methods: A literature search was carried out inclusive of the terms identify existing data and guidelines to determine best evidence based practice.

Discussion: Literature search identified aetiology of BCCs and methods of diagnosis and treatment. The search also highlighted an incidence rate of 0.0028 to 0.55% and complications associated with metastasis. The patient underwent a course of radiotherapy as surgery in this case was contraindicated due to history of excision of the parotid tail.

Risk factors for developing BCCs include intermittent sun exposure, ionising radiation, genetic predisposition and immunosuppression. Metastases occurs via the lymphatic system or haematogenously. Surgery is the main form of treatment and aims to be curative.
Fertility Behaviour of Adolescent Mothers in Northern Nigeria and Neonatal Mortality Risk: Mediating Effect of Quality Maternal Health Services
Authors: Alabi Matthew A. , Fasasi Motunrayo I. , Akanbi Mary O.
Published: November 2020

Background: Despite rising prevalence of high-risk birth and adverse birth outcome among adolescent mothers in Nigeria, there is paucity of studies relating childhood mortality risk with fertility behaviour of adolescent mothers. This study examines fertility behaviour of adolescent mothers in northern Nigeria and neonatal mortality risk.
Methods: Data were derived by pooling together the three most recent Nigeria Demographic and Health Surveys (NDHS, 2008, 2013 and 2018). The sample size comprises of weighted sample of 3,739 adolescent mothers 15-19 years with 5, 274 live births for the period under consideration. Survival analysis (cox proportional hazard model) was used to estimate the hazard of neonatal mortality risk as a result of risky fertility behaviour.
Results: Quality of maternal health service utilization was poor among (73.0%) of the adolescent mothers. The independent effect of adolescent fertility behaviour revealed a rise in hazard for neonatal mortality, with increasing high risk fertility behaviour, single high-risk (HR=2.69, p<0.001) and multiple high risk (HR=6.04, p<0.001). Adjusting for quality of maternal health service utilization, resulted in reduced hazard for neonatal mortality, though the result did not reach statistical significance (p>0.05). Adjusting for maternal, child characteristics and quality of maternal health service utilization, resulted in reduced hazard for neonatal mortality, though, the effect of risky fertility behaviour remained insignificant. Multiple birth babies were however, associated with elevated hazard for neonatal mortality (HR=11.4, p<0.05) relative to single birth babies.
Conclusion: Adolescent fertility behaviour was associated with elevated hazard for neonatal mortality.

Life Cycle Assessment (LCA) of an Integrated Solar PV and Wind Power System in Vietnam
Authors: LUU Quyen Le , VAN DOAN Binh , NGUYEN Ninh Quang , NGUYEN Nam Hoai
Published: November 2020

In Vietnam, energy generation accounts for more than half of the national greenhouse gas (GHG) emission. This sector has tremendous potential for emission reduction through the exploitation of renewable energy resources. This study examines the environmental impact of grid-connected solar and wind power in Vietnam, with a focus on GHG emissions. A life cycle assessment was conducted for these purposes. A case study of an integrated 50 kWp solar photovoltaics (PV) and 6 kW wind power model in the Central Highland of Vietnam was selected to illustrate the environmental impact of solar and wind power in Vietnam. The environmental inflows and outflows were quantified from raw material extraction for manufacturing components of the model, such as the panels, turbines, inverters and subsidiary components, to the end of life of the model. OpenLCA software was used for the calculation, with background data from publications and free LCA databases. The results obtained indicate that the life cycle GHG emissions are 20 gCO2e/kWh of solar PV, 3.7 gCO2e/kWh of wind power, and the total emission of the model during its 25-year lifetime is 38.28 tCO2e. If solar and wind power replace grid power, the lifetime emission reduction of the integrated solar and wind power model would be 1.8 thousand tCO2e.

Contracts of making, viewing and listening: Researching in and through films
Authors:   HDK-Valand - University of Gothenburg, Ranjan Ram Krishna
Published: November 2020

This paper tells the story of Contracts of making, viewing and listening, a 17-minute film that has emerged as part of my ongoing doctoral study in Artistic Research in Film. Taking the Bengal Famine of 1943 as a site-event, the doctoral research focuses on investigating and experimenting with epistemologies and ontologies of expressions emanating from a space of subalternity, especially Dalits. Contracts of making, viewing and listening can be seen as an artistic intervention into Satyajit Ray’s Distant Thunder – made in 1973, the film tells the story of effects of the Famine in rural Bengal through the eyes of a Brahmin couple. The artistic intervention was geared towards both critically reading the film from the lens of Dalit consciousness, and to explore ways of writing that critique in the language of the film itself. By retracing the journey of Contracts of making, viewing and listening, this paper focuses on how research is performed in and through the medium of film in this intervention, its multiple conceptual/material contingencies, and ultimately what it proposes in the context of artistic research.
L’ambivalence d’un chef-d’œuvre : Une lettre perdue de I.L. Caragiale
Authors: Modola Doina
Published: November 2020

"The Ambivalence of a Masterpiece: A Lost Letter by I.L. Caragiale. A Lost Letter by I.L. Caragiale, a landmark in the history of Romanian theatre, has enjoyed throughout time numerous critical interpretations, without losing its dramatic potential. We intend to study the comic mechanism through a variety of dramatic strategies: the diversity of the scenes, the circular actions, the baffling succession of situations, starting with the loss of the compromising love letter. This play features the actors of a political electoral farce overflowing with a vaudeville-like comic, that in conjunction with parody, is targeting the ideological clichés and verbal stereotypes. A logically inconceivable humour that borders the absurd. The purpose of this kind of humour, unleashed during comical situations, is not hiding the immorality, the demagogy of a socio-political reality put under the critical scope of the author. The joyful, bitter or cruel laughter are being in a continuous competition here. The humour is thus the element that subverts the values of political commitment.

Keywords: I.L. Caragiale, Romanian theatre, farce, vaudeville, humour, comedy, ambivalence.

Frei Luís de Sousa d’Almeida Garrett. Pour une approche pragmatique du texte dramatique
Authors: Dobroiu Vlad
Published: November 2020

"Frei Luís de Sousa by Almeida Garrett: a pragmatic analysis of the theatre dialogue. In this article, we analyse, from a pragmatic point of view, the dialogue of the play Frei Luís de Sousa by Almeida Garrett and its translation made by Maxime Formont at the beginning of the 20th century and published in Livourne. We focus on the strategies used by the participants in the theatre discourse in order to consolidate and sometimes even to renegotiate their interpersonal relationship. Our main interest concerns the use of nouns and pronouns in the 1st Act. For a better understanding of the socio-historical context of this play, we propose a short introduction to the 19th century, in Portugal. We also present and analyse some important para-textual pieces of information that accompany the translation made by Maxime Formont.

Marcel Proust : la Berma, figure de l’artiste, figure maternelle
Authors: Naturel Mireille
Published: November 2020

"Marcel Proust : The Berma, Actress’ Figure, Motherhood’s Character. La Berma is an actress in Proust’s novel À la recherche du temps perdu. Her main model is Sarah Bernhardt and she has the same beautiful voice, a golden voice. Both of them are famous for their role of Phèdre in Racine’s drama. Theatre represents firstly a family matter and a social challenge. The child discovers theatre outside theatre where he is not allowed to go, that is on posters from the Morris column. And the first approach is semiotic. Theatre is included in narration, through two performances that the hero attends. With them, we have an image of theatre in the 19th century, from a sociological and artistic point of view. In the first one, theatre is considered as a low art and actresses are immoral women. Theatre is a cruel world which leads from glory to death, brings rivalry between actresses. In the latter, theatre is above all a text; Proust is interested in gesture and costume. He is focused on the quality of interpretation in comparison with the role. He shows that interpretation is a real art, which can be compared to painting and music.

Keywords: art, gesture, interpretation, verse, voice, Phèdre, Proust, Sarah Bernhardt."
Trois scènes de bal dans le roman français (« La Princesse de Clèves », « Madame Bovary », « Le Ravissement de Lol V Stein »)
Authors: Popa Marius
Published: November 2020

"Three Ball Scenes in the French Novel (“La Princesse de Clèves”, “Madame Bovary”, “Le Ravissement de Lol V Stein”). This article aims to analyze – in a comparative manner – three ball scenes from novels belonging to leading authors of French literature (Madame de Lafayette, Gustave Flaubert and Marguerite Duras), highlighting a series of dramatic mechanisms used by novelists in the construction of such a diegetic plot. If La Princesse de Clèves describes a ball that takes place in the royal court, with all the typical scenes of the time (embodied in a real mixture of intrigue and gallantry specific to the living environment of the actors, which make the topos of the novel itself become a collective character), Madame Bovary describes, instead, a ball animated by the high society of the nineteenth century, with all the specifics of the realistic episteme (the ball becomes here an opportunity to evoke the painful contrast between different living environments, which the heroine cannot access and which causes her, consequently, to take refuge in an imaginary universe). Much closer to the spirit of contemporaneity, Le Ravissement de Lol V Stein, the famous “nouveau roman”, relies on an image of the harmful and destructive ball, paying particular attention to the psyche of the characters. These novels lean – starting from this narrative pretext of the ball – on some love stories built through specific strategies of the theatre, which is, in essence, the central object of our analysis.

Keywords: ball scenes, French Novel, dramatic mechanisms, narrative pretext, love stories."
Triple Personality: Creating, Performing and Appreciating Physical Theatre
Authors: Gavriliu Andrea
Published: November 2020

"This article represents a closer examination of the triadic perspective of creating, performing and appreciating a performative event. This type of analysis is directly linked to choreological studies, a domain which is not yet part of the Romanian academic field, but, in essence, it does exist through other forms of theatrical studies and practices. I localize every scholarly aspect in current performative practices, more precisely, in that of physical and dance theatre. Through this article I would like to bring more attention to the way these forms of performing arts are created, performed and spectated by individuals who are able to deal with all three processes. Therefore, this analysis will have a more personal mark, thanks to the interviews integrated, with two internationally known artists in physical theatre: Hannes Langolf and Rob Hayden. It is a closer unveiling of how processes of transaction function within a piece of work. It is a way of constant questioning every participant in an artistic event should confront him/herself with.

Factors of the circular economy development
Authors: Ratner S.V.
Published: November 2020

Subject. Today the circular economy is viewed as a new model of economic growth that allows overcoming resource constraints. Despite the general understanding that environmental problems are the main incentive for the transition to circular models of production and consumption, the underlying factors in the development of this economic model have not been fully studied in modern literature. Are circular production models available only to technologically highly developed rich countries, or, conversely, poverty and a total lack of resources are the best incentive for the development of a circular economy?
Objectives. I study the influence of such factors as the general economic and innovative development of the country, as well as the State's innovating activity to form and develop circular models of economic growth.
Methods. The research was carried out with methods of econometric modeling. Eurostat data were used as an underlying source of information.
Results. The study showed that the high level of the national economic development positively influences the resource efficiency of an economy, but more advanced countries produce more waste in the consumption sector. Production and consumption waste recycling demonstrates better trends in less economically developed countries. Countries with substantial innovation expenditures tend to have more robust municipal and industrial waste recycling technologies, as well as a more effective use of secondary materials. The development of an e-waste recycling system is essentially dependent on government incentives for innovation in this area.
Conclusions. The findings can be used for outlining national federal and regional programs for the development of production and consumption waste recycling mechanisms in Russia. Social entrepreneurship and business initiative may appear one of the priority mechanisms spurring the circular economy in Russia through traditional patterns of resource-saving consumer behavior.

Authors: Rodnyanskii D.V.
Published: November 2020

Subject. Currently, traditional methods and tools of public administration in the oil industry cease to be effective. As external factors put more pressure (agreements of OPEC+, energy price volatility), digital transformation of business and public administration and accelerating changes in the economic system, respective authorities need to refine their tools to manage the industry. Objectives. I provide the rationale for transforming the system of public administration in the Russian oil industry, articulate the concept of the process- and project-based model of sectoral management and determine its tools and elements. Methods. I rely upon analytical methods, such as the statistical and retrospective analysis, and the mathematical modeling framework to prove the reasonableness and accuracy of my conclusions. Results. I provide the concept of the process- and project-based model of the sectoral management in Russia's oil industry, substantiate its strengths, describe its targets, elements and mechanisms. Conclusions and Relevance. Sectoral authorities should supplement traditional methods of sectoral regulation with tools of process- and project-based approaches, thus substantially improving the quality and timelines of the regulator's decisions, and make the Russia oil enterprises more competitive.

Hearing Amplification Improves Eye Movements: A Case Study
Authors:   University Of Paris, Kapoula Zoï
Published: November 2020

Background: Using two different approaches, we study the possible interaction between the sound and the preparation and execution of eye movements. The first approach deals with the sensory modalities of the target to which eye movements are made, the second with the hearing amplification of the subject. Material: Saccades and vergence were tested for a healthy 19-year-old student performing his internship in the lab. Tests with visual vs audiovisual targets were done. The normal hearing participant performed all tests with a hearing bilateral device that was adjusted in different conditions either at zero (no amplification), moderate amplification, or high amplification. Experimentations were made over a month, and the different tests were executed following a Latin square design. Results: We found statistical differences between eye movements towards audio-visual targets and visual targets in the absence of hearing amplification. The presence of the sound component on the stimulus improved the preparation and execution of saccades and impacted the execution of vergence. The hearing amplification has a differential impact on eye-movements towards visual targets. For vergence, it significantly reduced the amplitude of convergence. For saccades, it increased the amplitude and decreased the latency. These results could be due to an arousal state elicited by the amplifying background noise and sound coming from the participant himself. Conclusion: This pilot study opens the investigation of the different interactions between sound and saccade and vergence eye movements. We hope that these results will inspire other studies.

İmplantasyon sürecinin penetrasyon fazında, implantasyon alanı çevresinde vasküler değişimler meydana gelir. Bu vasküler fizyolojinin düzenlenmesinde etkili olduğu bilinen COX-2, tekrarlayan gebelik kayıplarının (TGK) etiyolojisinde de önemli rol oynamaktadır. TGK’nın büyük oranda penetrasyon fazında ve gebeliğin 8-12. haftalarında oluşması, blastosist implantasyon sürecindeki olumsuzluklara bağlı olarak gelişebileceğini düşündürmektedir. TGK’nın tedavisinde, klinikte sıklıkla kullanılan düşük molekül ağırlıklı heparinin (DMAH), antikoagulan etkisinin yanında antiinflamatuar etkilerinin de fayda sağlayabileceği yapılan çalışmalarda bildirilmiştir. Bu çalışmada, sıçanlara gebeliğin 0, 1, 3, 5 ve 7. günlerinde 50 IU/kg enaksoparin sodyum, intraperitoneal olarak uygulanmış ve toplanan uterus dokularında COX-2 immunlokalizasyonları belirlenmiştir. DMAH’ın gebeliğin erken dönemlerinde sıçan uterus dokusunda TGK etyolojilerinde yer aldığı bilinen COX-2 ekspresyonu üzerinden bir etkiye sahip olup olmadığı araştırılmış ve DMAH uygulamasının, immunohistokimyasal seviyede ve semikantitatif gözlemde COX-2 immunekspresyonu üzerine bir değişiklik oluşturmadığı sonucuna varılmıştır.

CHRONIC COMPLICATION OF FOREIGN BODY IN TRACHEOBRONCHIAL TREE : A CASE REPORT
Foreign body aspiration in tracheobronchial could be life threatening particularly if the object large enought to cause nearly complete obstruction.  In the other hand small object could pass beyond carina and cause less severe sign and complication manifest. Chronic  symptoms with recurrent infection that lead to brochiectasis may occur in delayed of extraction. We presented a case of nail aspiration  by a 17 years old male patients who presented with  hemoptysis. The patient had history of nail aspiration six months ago and had no symptom until the last one week . First attempt of evacuating  used rigid bronchoscopy  under general anesthesia had failed. Fiber optic bronchoscopy (FOB) found the nail at the orificium of right lower lobe and chest computed tomography stated the  occurancy of bronchiectasis at distal of nail. The extraction was performed by FOB with local anesthesia succeeded to remove the nail to the laring that induced cough and nail threw out. There were no major complication and further symptoms after the extraction. Eventhough aspiration small object cause no symptom, it could lead  to chronic complication such as bronchiectasis. FOB for removing the object is supposed to perform carefully because the object could fall on another part of brochial tree when it was  pulled out.

Anxiety is a response to a threat that comes nowhere, internally, indistinctly or conflictually. One common cause of the anxiety in the world is a patient that will experience an operation. The incidence is about 11-80% in the world. There are some risk factors that impact the anxiety of pre-operative patient like ages, education levels, operation histories, information resources, and etc. This study aimed to give the incidence of the anxiety of cesarean section pre-operative patients with spinal anaesthesia at Siti Hawa’s Mother and Child Hospital Padang. Specifically, cesarean section is chosen to be observed because this surgery is the most common operation in the world and spinal anesthesia is the main choice because of its rapid onset and low failure. This study was an observational-descriptive with cross-sectional design done from July until August 2018. Data were collected by direct interview with eighty-three respondents using The Amsterdam Preoperative Anxiety and Information Scale (APAIS) questionnaire. This result of this study based on APAIS questionnaire were (51,8%) patients does not feel anxiety and the most need for information was low (48,2%). The highest frequency of preoperative anxiety were patients twenty to thirty-five years old (54%), based on education levels (62,9%) patients graduated from college, based on operation histories (63%) patients that hadn’t experience the operation yet, and based on the information resources (53,3%) patients who had known the operation procedure.

Timbal (Pb) merupakan suatu logam berat yang bersifat toksik bagi tubuh. Timbal dapat menginduksi pembentukan radikal bebas yang dapat menimbulkan stres oksidatif sehingga berujung pada kematian sel. Kematian sel menstimulasi peningkatan enzim hati seperti SGPT dan SGOT. Tubuh memerlukan antioksidan eksogen untuk menghambat stres oksidatif akibat radikal bebas. Daun jamblang mengandung antioksidan alami seperti flavonoid dan fenolik yang dapat menangkal radikal bebas. Penelitian ini bertujuan untuk mengetahui efek proteksi pemberian ekstrak daun jamblang terhadap peningkatan aktivitas serum glutamate pyruvate transaminase (SGPT) tikus jantan yang diinduksi timbal asetat.
Penelitian ini adalah penelitian eksperimental dengan rancangan randomized post test only group design menggunakan 15 ekor tikus jantan yang dibagi atas 3 kelompok yaitu kelompok kontrol negatif (K-) yang diberikan pakan standar, kelompok kontrol positif (K+) yang diberikan pakan standar dan timbal asetat dosis 40 mg/KgBB per oral, kelompok perlakuan 1 (P1) yang diberikan pakan standar serta timbal asetat dosis 40 mg/KgBB dan ekstrak daun jamblang dosis 150 mg/KgBB per oral. Penelitian ini dilakukan selama 28 hari dan di hari ke-29 tikus dimatikan lalu diambil serumnya untuk diperiksa kadar SGPT. Pemeriksaan kadar SGPT menggunakan tes berdasarkan kriteria IFCC tanpa pyridoxal phosphate dengan metode Sample Start. Data dianalisis dengan uji Shapiro Wilk, uji One Way Anova dan uji Post Hoc Tukey’s HSD.
Hasil penelitian ini menunjukkan rerata kadar SGPT kelompok kontrol negatif (K-) 46,6 U/L, kelompok kontrol positif (K+) 73,9 U/L, dan kelompok perlakuan 1 (P1) 62,0 U/L. Hasil ini menunjukkan perbedaan bermakna rerata kadar SGPT semua kelompok hewan coba yang dibuktikan dengan nilai p < 0,05.
Kesimpulan penelitian ini adalah adanya efek proteksi pemberian ekstrak daun jamblang terhadap peningkatan aktivitas SGPT tikus yang diiinduksi oleh timbal asetat.

This study aims to explore investment, financial, and trade freedom impact on banks’ risk-taking. A unique dataset of large commercial banks of the USA covering the period 2002-2018 is used. The findings prove that financial freedom reduces the bank’s risk-taking whereas investment and trade freedom increase the risk-taking of large commercial banks in the observed period. The behavior of risk-taking due to financial, trade and investment freedom of under-capitalized and low-liquid banks seems to be marginally less impacted as compared to well-capitalized and high-liquid banks. The findings are robust using loan loss reserves as a risk measure and subclassification of a sample. The results suggest that the intervention of the government is decisive in developing the degree of economic freedom for the stability of the financial system.

Published: November 2020

Se examina la evolución del empleo en la industria de la construcción en México y se analizan sus determinantes principales mediante la estimación de un modelo de panel de datos espaciales para el periodo 1980-2013. Los hallazgos muestran que el empleo es muy sensible a las variaciones de las remuneraciones reales, las cuales tienen efectos directos negativos; se observó que existe una alta elasticidad producto del empleo, mientras que la productividad total factorial no tiene efectos de interacción espacial sobre la ocupación. Se concluye que en el sector de la construcción se cumple la hipótesis de los salarios de eficiencia.
