Authors: Feng Yuan , Liu Xinran , Han Yueqing , Chen Mantian , Zhang Lin , Hu Yuling , Chen Liya , Chen Gang , Li Ning
Published: August 2020

Background & Objective:

Nowadays, the interaction between natural products and microRNAs provides
a promising field for exploring the chemopreventive agents for various cancers. As a member of microRNAs,
the expression of let-7f-5p is universally downregulated in Colorectal Cancer (CRC). The present study
aimed to uncover the function of let-7f-5p in the proliferation of human colon cancer cell line Caco2 and explored
chemopreventive agents from natural resources that can prevent the development of CRC.

Methods:

Herein, Caco2 cells were transfected with let-7f-5p mimic and inhibitor to manipulate let-7f-5p levels,
and the expression of let-7f-5p was performed by RT-qPCR. Next, we determined how let-7f-5p regulates
Caco2 cell proliferation by using MTT, wound-healing, cell cycle, and colony formation assays. Besides, to
further understand the effect of let-7f-5p, we evaluated the protein level of AMER3 and SLC9A9 by using western
blotting assays.

Results:

The results showed a suppressive function of let-7f-5p on Caco2 cell proliferation and then put forward
a triterpenoid (Rotundic Acid, RA) which significant antagonized the effect of cell proliferation, restitution after
wounding, and colony formation caused by let-7f-5p. Moreover, the western blot results further indicated
that the inhibitory effect of RA might be due to its suppressive role in let-7f-5p-targeted AMER3 and SLC9A9
regulation.

Conclusion:

Our validation study results confirmed that let-7f-5p was a potent tumor suppressor gene of Caco2
cell proliferation, and RA showed as a regulator of the effect of let-7f-5p on cell proliferation and then could be
a potential chemopreventive agent for CRC treatment.

Published: August 2020

Background:

Conventional cancer therapeutics has enormous toxicity and severe side effects that generate multi-drug resistance. Therefore, an urgent need exists for new alternative therapeutic agents for cancer treatment. Cepharanthin (CEP) has anti-cancer potential but has poor aqueous solubility, which limits its clinical use. Nanosuspensions (NS) are attractive as insoluble drug delivery systems.

Objectives:

In this study, we used D-alpha Tocopherol acid Polyethylene Glycol Succinate (TPGS), Polyvinylpyrrolidone (PVP) VA64, and Croscamellose Sodium (CCS) as stabilizers to produce TPGS-CEP-NS, PVP VA64-CEP-NS, and CCS-CEP-NS by wet-milling technology, and then characterized the NS and evaluated their functional activities in vitro.

Methods:

EP Nanosuspensions (CEP-NS) were prepared by the wet-milling method. The prepared NS were characterized by particle size distribution, zeta potential, morphology, surface properties, and molecular interactions. The NS were evaluated for their effects on HepG2 cells in vitro. The evaluations included assessment of cellular cytotoxicity, cellular apoptosis, NS uptake by cells, and mitochondrial membrane potential changes.

Results:

CEP-NS showed an appropriate particle size and were physically stable. All CEP-NS exhibited HepG2 enhanced anti-proliferative effects by reducing cell viability, enhanced cellular uptake, induced cellular apoptosis, and mitochondrial membrane potential loss.

Conclusion:

: CEP-NS may be effective therapeutic agents for the treatment of hepatocellular carcinoma.

Authors: Noviardi Febri , Rahmanto Andre Noevi , Slamet Yulius
Published: August 2020

This paper explains how the process of rebranding the logo of the Directorate General of Taxes (DGT) of the Republic of Indonesia carried out by DGT public relations in shaping the image by displaying the cultural values of the Ministry of Finance. This is motivated by the lack of a comprehensive explanation of the process of rebranding the logo in previous studies. At DGT, logo rebranding is carried out because of the low level of the public’s trust in the DGT. Therefore, one of the strategies of the DGT public relations is the formation of an institutional image. This study uses a research method with a qualitativeapproach with data collection conducted by interviewing selected informants using purposive sampling techniques and source triangulation as a technique in testing the validity of the data. The results are analyzed using the Assessment, Communication and Analysis, Design, and Action planning model. The rebranding process was 1) describing the problem, 2) using all channels communication and objectives in delivering a new logo, 3) using professional consultants in planning that consist of research, strategy development, and implementation, 4) as well as carrying out plans, setting rules, and supervising all activities in the DGT’s rebranding process.Tulisan ini menjelaskan bagaimana proses rebranding logo Direktorat Jenderal Pajak (DJP) RI yang dilakukan oleh Humas DJP dalam membentuk citra dengan menampilkan nilainilai budaya organisasi Kemenkeu. Hal ini dilatarbelakangi oleh kurangnya penjelasan yang komprehensif terhadap proses rebranding logo pada studi-studi sebelumnya. Pada DJP, rebranding logo dilakukan karena rendahnya tingkat kepercayaan masyarakat terhadap DJP. Oleh karena itu, salah satu strategi Public Relations (PR) adalah dengan pembentukan citra institusi. Penelitian ini menggunakan metode penelitian dengan pendekatan kualitatif dengan pengumpulan data dilakukan dengan cara wawancarakepada informan terpilih menggunakan teknik purposive sampling dan triangulasi sumber sebagai teknik dalam uji keabsahan datanya. Hasilnya dianalisis menggunakan model perencanaan Assessment, Communication and Analysis, Design, dan Action. Proses rebranding yang dilakukan yaitu 1) menggambarkan masalah, 2) menggunakan semua saluran komunikasi dan tujuan dalam memberikan logo baru, 3) menggunakan konsultan profesional dalam perencanaan yang terdiri dari penelitian, pengembangan strategi, dan implementasi, 4) serta melaksanakan perencanaan, menetapkan aturan,dan melakukan pengawasan terhadap seluruh kegiatan pada proses rebranding Ditjen Pajak RI.

Authors: Lapadat Laura , Balram Anusha , Cheek Joanna , Canas Eugenia , Paquette Andrea ,   Bipolar Youth Action Group, Michalak Erin E
Published: August 2020

Background

We describe the methodological dimensions of community-based participatory research through a description of study design, youth engagement, and methods/processes in the cocreation of knowledge within a Canadian study, the Bipolar Youth Action Project. This collaborative partnership—carried out by a team composed of academic, community, and youth partners—was designed to investigate self-management and wellness strategies for young adults living with bipolar disorder.

Objective

The aim is to describe the opportunities and challenges of this collaboration and to reflect upon the process of involving youth with bipolar disorder in health research that concerns them, and share lessons learned.

Methods

The project was conducted in multiple phases over 2 years: (1) grant-writing, with youth contributing to the process; (2) recruitment, in which 12 youth were selected and trained to help shape and conduct two research forums; (3) the first research forum, where more youth were consulted about the strategies they apply to stay well (self-management strategies); (4) data analysis of Forum I findings; (5) research Forum II, which consulted youth with bipolar disorder about knowledge translation of Forum I findings; and (6) data analysis of Forum II findings. Youth peer researchers with bipolar disorder were involved in a significant capacity at every stage in the process.

Results

Of the initial 12 youth peer researchers, 7 remained on the project from the recruitment phase until the project ended. They collaborated in the creation of two youth research forums that consulted youth with bipolar disorder on their self-management strategies.

Conclusions

This article shares what was learned from the process of partnering with youth with bipolar disorder in a community-based participatory research study.
Impact of The Social Media on COVID-19: Is YouTube In or Out? (Preprint)
Authors: Eyuboglu Gokhan , Guven Ramazan , Yilmaz Semerci Seda , Ozel Deniz , Sasmaz Muhammed Ikbal
Published: August 2020

BACKGROUND

The COVID-19 pandemic, which caused to closure of borders and curfews to be imposed all over the world, is one of the most important urgent public health problems in the last century. Youtube with billions of viewers per day has become one of the information points for COVID-19 in this period while face to face meeting is diminished. Many COVID-19 patients have talked about their experiences on Youtube.

OBJECTIVE

With this study, it has been aimed to evaluate the proficiency of videos about COVID-19 symptoms on Youtube.

METHODS

The terms “COVID 19 symptoms”, “coronavirus 19 symptoms”, “symptoms of coronavirus” and “symptoms of COVID 19” have been searched on Youtube on 01 April 2020, the videos that were uploaded in 2020 and viewed more than 10,000 times until then were scanned and 719 videos were examined. Records of duplicated videos have been excluded. Videos with an inappropriate language, videos with a duration of shorter than 1 minute, videos that have been deleted by the uploader and videos that contain information incompatible with the title excluded. The videos were examined by two physicians in terms of discussing the symptoms and wrong information and graded. In case there was a difference between two evaluators, peer-review has been made by a third reviewer.

RESULTS

A total of 719 videos were scanned and 202 videos were included in the study. 28.7% of the videos had been viewed more than 500,001 times. Among the uploaders Healthcare Personnel (3.5%) and Institutions (9.4%) are the two lowest groups. No grading difference has been found between Institutions, Healthcare Personnel, Individuals Other Than Healthcare Personnel and Unknown Uploaders (P: .13). Among the uploader groups with 12 and higher points, Individuals Other Than Healthcare Personnel stood out among other uploaders significantly with a ratio of 46.7% (P: .02). Only 4.1% of the videos included wrong/imperfect information and a statistically significant relation between uploader groups was not determined (.35).

CONCLUSIONS

It is important that COVID-19 symptoms are reflected correctly on Youtube, which is one of the most frequently used sites all over the world, in terms of people recognizing the disease in the time of pandemic and isolating themselves and making the decision to apply for a healthcare provider. We are of the opinion that creation of more content by healthcare personnel, in a period with such heavy social media usage, will be useful in terms of informing the public.
Improving Predictions of COVID-19 Preventive Behavior: Development of a Sequential Mediation Model (Preprint)
Authors: Roberts James A , David Meredith E
Published: August 2020

BACKGROUND

Since the beginning of the COVID-19 pandemic, social distancing, self-quarantining, wearing masks, and washing hands have become part of the new norm for many, but not all. It appears that such preventive measures are critical to “flattening the curve” of the spread of COVID-19. The public’s adoption of such behaviors is an essential component in the battle against what has been referred to as the “invisible enemy.”

OBJECTIVE

The primary objective of this study was to develop a model for predicting COVID-19 preventive behaviors among US college students. The Health Belief Model has a long history of use and empirical support in predicting preventive health behaviors, but it is not without its purported shortcomings. This study identifies a more optimal and defensible combination of variables to explain preventive behaviors among college students. This segment of the US population is critical in helping slow the spread of COVID-19 because of the relative reluctance of college students to perform the needed behaviors given they do not feel susceptible to or fearful of COVID-19.

METHODS

For this study, 415 US college students were surveyed via Qualtrics and asked to answer questions regarding their fear of COVID-19, information receptivity (seeking relevant information), perceived knowledge of the disease, self-efficacy, and performance of preventive behaviors. The PROCESS macro (Model 6) was used to test our conceptual model, including predictions involving sequential mediation.

RESULTS

Sequential mediation results show that fear of COVID-19 leads individuals to seek out information regarding the disease, which increases their perceived knowledge and fosters self-efficacy; this is key to driving preventive behaviors.

CONCLUSIONS

Self-imposed preventive measures can drastically impact the rate of infection among populations. Based on this study’s newly created sequential mediation model, communication strategies for encouraging COVID-19 preventive behaviors are offered. It is clear that college students, and very possibly adults of all ages, must have a healthy fear of COVID-19 to set in motion a process where concerned individuals seek out COVID-19–related information, increasing their store of knowledge concerning the disease, their self-efficacy, and ultimately their likelihood of performing the needed preventive behaviors.

LA FIGURE DU PÈRE DANS LES CHRONIQUES FAMILIALES DEMARGUERITE YOURCENAR ET DE LUAN STAROVA
Authors: Popovska Elisaveta
Published: August 2020

Dans leurs chroniques familiales, Marguerite Yourcenar et Luan Starova mettent en honneur le rôle bienfaisant de leurs pères respectifs. Bien qu’ils incarnent différents milieux sociaux (la bourgeoisie aisée dans le cas de Yourcenar, l’émigration intellectuelle dans le cas de Starova), ces pères ont exercé, directement ou indirectement, une influence déterminante dans la formation intellectuelle de leurs enfants. Possédant une vaste érudition, en grande partie acquise par l’autodidaxie, les deux pères ont insufflé aux futurs écrivains l’amour pour les livres. Les bibliothèques qu’ils possédaient et les lectures qu’ils proposaient à Marguerite et à Luan ont non seulement façonné le goût littéraire de ceux-ci mais les ont également préparés pour un affrontement lucide avec les hauts et les bas que leur offrirait la vie. Ces pères encourageaient les débuts littéraires de leur progéniture et, plus tard, autant que la durée de leur vie le leur permettrait, se sont montrés lecteurs assidus et commentateurs avisés des œuvres de leurs enfants devenus écrivains. Yourcenar et Starova dans leurs chroniques familiales vont bien au-delà de la mémoire personnelle et se plongent dans la mémoire familiale dans toutes ses manifestations : généalogique, référentielle, rituelle, corporelle, volontaire, involontaire... L’histoire familiale se montre ainsi une présence qui habite constamment ces auteurs et qui ressurgit dans leurs écrits par l’évocation des résonnances d’un passé plus ou moins éloigné.
BRANDING AND BRAND AS FACTOR OF THE COMPETITIVE ADVANTAGE IN SPORTS
Authors: Bačevac Srećko , Veselinović Jovan , Životić Dragan
Published: August 2020

The basic purpose of this research is based on the analysis of scientific-theoretical-practical knowledge in the field of brand management, with special emphasis on the brand as a significant factor of organizational competitive advantage and establishing a leading position in the sports market. By examining a wide variety of theoretical knowledge, we come across definitions that are based on the views of world’s leading marketing experts who point out that the basic function of marketing is brand building. Building, consolidating and expanding the brand require dimensions of clarity, consistency and leadership, adapted to the environment, with particular emphasis on competitive advantage, technology and on establishing a leading position in the market. Referring to the adequate literature, this paper covers the complete branding strategy, starting from the general ones that define the branding strategy as the most powerful communication tool; from strategies that are based on definitions that the key to success is the achievement of competitive advantage and the establishment of a leading position in the market; towards specific strategies who explore the basic elements of the branding strategy and their impact on the company’s business and productivity, as well as the impact on the consumers’ awareness.

Published: August 2020

The goal of this paper is to analyse the relationships and differences among volleyball teams, participants of the 2018 World Cup in Japan, divided into three categories by their final standings (1st to 4th place, 5th to 8th place and others), based on the elements of situation-based efficiency. For the purposes of this paper, information from the official match reports (p 2 report) related to the way of winning points in the match was used, and these data were analysed using the program Volleyball Information System (VIS). The data obtained were analysed in relation to the team category and the outcome of the match. The data were obtained using descriptive and comparative statistical procedures. The survey sample includes all the women’s volleyball championship games played in Japan in 2018. Based on the final standings, the teams were divided into three groups: 1) the teams who reached the 3rd stage of the tournament (6 teams, from 1st to 6th place); 2) the teams that finished the competition in phase 2 (10 national teams, ranking 7th to 16th); 3) national teams that finished the competition in phase 1 (8 national teams, ranking 17th to 24th). The results obtained indicate that the teams had an equally good performance of the block and serve game elements; statistically these were not significant for the match outcome, but they rather serve as an aid for the overall game and for the final outcome of the match. The results of this research also highlight the spike as the key element affecting the positive end result of the match. It is important to emphasize that the opponent errors are a factor that depends exclusively on the opponent, but they also determine the overall score of the winning team.
THE RELATIONSHIP BETWEEN MAXIMAL STRENGTH, VERTICAL JUMP, ACCELERATION AND CHANGE OF DIRECTION PERFORMANCE
Authors: Ranisavljev Igor , Matić Milan , Janković Nenad
Published: August 2020

The goal of the present study was to explore the relationship between maximum strength, the vertical jump, acceleration and change of direction performance in healthy young male students. The sample of variables included the following variables: body mass (BM), one repetition maximum on the half-squat test (Squat 1RM), one repetition maximum normalized for body mass (Squat 1RM_rel), peak power during the concentric phase of countermovement jump (Ppeak CMJ), vertical jump height during CMJ (CMJ_H), time for the 20m sprint (20m Srint) and time for the agility T-Test (Agility T-Test). The relationship was tested with the Pearson Coefficient of linear correlation (r). The results showed significant correlation between body mass with Squat 1RM_rel and peak concentric power during CMJ (r=-.424, and r=.377, respectively). Peak concentric power during CMJ additionally has a significant correlation with the change of direction abilities, 20m sprint, and vertical jump height, (r=-.401; r=-.467; r=.656; p<0.05, respectively). Also, significant correlation was determined between the 20m Sprint and Agility T-Test (r=.443; r=-.570, respectively), and Agility T-Test vertical jump height (r=-.498).  The level of relationships between maximum strength, acceleration, COD and CMJ may be attributable to differences in the control and coordination of several muscle groups during execution of these tests.
Tafonomía lítica del sitio Quebrada de Quereo
Authors: Carranza Elola Javier , Méndez César
Published: August 2020

This paper aims to develop an analytical proposal for dealing with ambiguity in lithic material of late Pleistocene contexts in alluvial locations. We focus our study on the Quebrada de Quereo site (13480-13070 cal BP) located in the coast of Northern Semiarid Chile. To build a comparative analog, different combinations of taphonomic and technological variables are explored in an assemblage of natural origin from a nearby ravine that mimics lithic knapping attributes. This same set of variables was tested on the anthropogenic lithic assemblage of the Quebrada Santa Julia site (12990-12730 cal BP). This procedure allowed us developing an analytic system centered on the characteristics of chipped edges to weigh taphonomic and technological attributes and their natural production in torrential ravine contexts. By applying this scheme to a sample of the lithic material of Quebrada de Quereo, we discuss which pieces are most likely to be considered as lithic artifacts. We conclude that most of the Quebrada de Quereo lithic assemblage may be explained as produced by natural causes, thus those pieces should be considered pseudo-artifacts.
Trama y urdimbre
Authors: Pey María Laura
Published: August 2020

In this article, I interpret the occupational history of the archaeological site Huayatayoc (Cusi Cusi, Jujuy Puna) considering the multiplicity of practices and logics that could interact in the dwelling of this productive locus over time. The study of this case allows me to discuss the interpretative model that has been used in the study of the region. This model considers pastoral and agricultural logics as excluding and discrete in the landscape. I propose the consideration of a third logic - agropastoralism - and I make a first approximation towards a textile analogy to interpret the way in which these ways of understanding, constructing and relating to the environment could be intertwined in the local landscape.
Keywords: agricultura, pastoralism, agropastoralism, dry puna, archaeology.

Republicanismo: vitalidade de um conceito à luz das heranças da modernidade
Authors: Scheiner Lívia Mauricio , Simões Rafael Cláudio
Published: August 2020

Recuperar a dimensão histórica da ideia de republicanismo torna-se, atualmente, uma necessária contribuição dos estudos históricos para a compreensão das tradições e dos elementos contemporâneos que estão envoltos neste conceito. Dimensionar a sua construção desde as repúblicas italianas, no Renascimento, passando pela Revolução Inglesa do século XVII até chegarmos às revoluções Americana e Francesa do século XVIII, com suas discussões centradas nas ideias de liberdade, virtude cívica e participação, permite-nos aquilatar, para além da formação do próprio conjunto de valores desse ideário, as disputas e apropriações que rondam este conceito na atualidade. Por meio da análise de escritos políticos clássicos da Modernidade inglesa e francesa e, à luz da presente historiografia sobre o tema, o presente artigo pretende adensar a reflexão sobre as heranças modernas das atuais apropriações do republicanismo como construto teórico e como prática política.

Published: August 2020

This study presents 2-D simulations of a flow-through a sudden expansion/contraction micro-channel with the existence of obstacles. The bottom wall is maintained at constant flux, while the other walls are adiabatic. Rectangular adiabatic obstacles are mounted before the expansion region on the upper and lower wall of the channel used. The finite element method was used to discretize the equations that govern the physical model. Results indicate the apparition of a separate vortex, situated in the corner after the sudden expansion of the micro-channel for low Reynolds numbers. For higher values and expansion ratios, the vortex separation length increases. The obtained results show that the obstacles have a considerable effect on the dynamics of the flow and enhancement of heat transfer.
Investigations on melting and solidification of a battery cooling system using different phase change materials
Authors: Pradeep Ramu , Venugopal Thangavel
Published: August 2020

The temperature of battery modules in electric vehicles must be controlled adequately to remain within a specified range for optimum performance. In this research work, thermal management of battery modules with PCM was investigated experimentally and computationally. The Li-Ion battery pack cooled with a PCM for removing heat generated during the battery charging and discharging cycles. Computations and experiments were carried out to estimate the heat transfer, solidification and melting characteristics of the PCM used in the thermal management of a Li-Ion cell module. Four PCM (GR44, RT50, OM35, and paraffin wax) with different melting temperature were used for the study. Battery operating temperature and melting point are the key parameters for selection of PCM. Experiments have been carried out only for OM35 and paraffin wax, because OM35 melting point is within the battery operating temperature and paraffin wax for considering harshest condition. The OM35 melting temperature range is below 35?C which is accordance with a desire to keep battery temperature below that temperature. Based on experimental and simulation results, it was found that OM35 is keeping battery temperature range minimal, which was the ideal for Li-Ion battery thermal management.

The efficient utilization of waste from food industry is possible after thermal treatment of the material. This treatment should be economically feasible and compromise the energy efficient drying process. The main goal of this investigation is to determine drying characteristics of nectarine pomace as a waste from food industry. The measurements were performed in an experimental dryer by combined conductive-convective drying method with disk-shaped samples of 5, 7, and 10 mm thickness and 100 mm in diameter at the air temperatures of 30, 40, 50, 60, and 70?C, hot plate temperatures of 50, 60, and 70?C and air velocity of 1.5 m/s. The drying curves were compared to a few semi-theoretical mathematical models. The Logarithmic model showed the best correlation. On the basis of experiments, it is determined that the drying process takes place in a falling rate period and it is accepted that the main mechanism of moisture removal is diffusion. The effective coefficient of diffusion was determined using experimental results by calculating the slope of the drying curves. Drying time and equilibrium moisture are determined for each experiment. Analysis of drying curves showed that the conductive-enhanced drying method reduces drying times and increases the diffusivity coefficient. The character of drying rate curves for conductive-enhanced drying was analysed and compared with pure convective drying of nectarine pomace.
CEO Overconfidence and the Timeliness of Goodwill Impairments
Authors: Chung Byung Hun , Hribar Paul
Published: August 2020

We use survival analysis techniques to examine whether overconfidence affects the likelihood and timeliness of goodwill impairments. We predict that overconfident CEOs have a lower likelihood of impairment in any firm-quarter, and take longer, on average, to impair goodwill. Using the Cox proportional-hazards model and the accelerated failure time model, we find evidence consistent with both predictions. In cross-sectional tests, we find having more financial experts on the board mitigates the effect of CEO overconfidence on the timeliness of goodwill impairments, while uncertainty in predicting a firm's future performance strengthens the effect. Additional results show that overconfident CEOs hold overly optimistic expectations of their firms' performance, and that they underweight negative market signals prior to the impairment decisions.

Published: August 2020

Abstract: Living things need nutrients to grow and their endurance. The presence of nutrients around plant roots is very important for microorganisms as biological control agents and also for plant pathogens. PGPR Plant Growth Promoting Rhizobacteria (PGPR) has a role in increasing plant growth, crop yields and plant growth. Bacteria in PGPR can actively colonize the rhizosphere. Bamboo roots are colonized by many bacteria (Pseudomonas fluorescens), these bacteria can play a role in increasing the solubility of P in the soil, certain strains of Pseudomonas sp. can prevent plants from fungal pathogens that come from the soil. Rhizobacteria from the Bacillus spp. and Pseudomonas spp., able to dissolve phosphate, while the Serratia spp. group, in addition to being able to increase the availability of P (phosphate) can also fix nitrogen and be able to synthesize IAA. Microbes with the ability to produce phytohormone are an effort to help in increasing plant growth.

Published: August 2020

Baia Mare region is one of the most polluted areas from our country due to extraction and processing of ores with high content of Cd, Cu, Pb, Zn and precious metals. The main objectives of the present study were: to assess the groundwater quality by determine the physico-chemical parameters values, dissolved ions and heavy metal concentration and to evaluate if those groundwater sources can be used for irrigation and drinking purposes by calculating 10 specific quality indexes. A total of 70 groundwater samples were collected from 14 private wells and springs from Baia Mare and surrounding areas (November 2013 and December 2013, June 2014, September 2014 and December 2014). In situ a portable multiparameter WTW Inolab 320i respectively a portable turbidimeter were used to determine the physico-chemical parameters like: pH, ORP, EC, TDS, DO, salinity and turbidity. The dissolved ions (Li+, Na+, NH4+, K+, Mg2+, Ca2+, F-, Cl-, Br-, NO2-, NO3-, PO43-, SO42-) were analysed in laboratory by using an ion chromatograph IC DIONEX 1500. An atomic absorption spectrometer ZEENIT 700 was used to determine the heavy metals concentrations like: Cd, Fe, Mn, Ni, Pb and Zn. After calculating the specific quality indexes (WQI, MI, HPI, PI, SAR, % Na, SSP, MH, MR and KR), the obtained results indicated that the majority of the investigated water sources are not recommended for drinking and most of them are suitable to be used only like irrigation waters.
THE CHRISTIAN-ORTHODOX FAITH AND CHRISTIAN TRANSHUMANISM
Authors: CIRA Călin Emilian
Published: August 2020

The Church has been confronted with various challenges in the recent period. One of these is the transhumanist movement that aims to create a new man by using the means of science and technology. In this context, the Christian Transhumanist Association was set up, an organization which proposes a dialogue with Transhumanism and even a way to find compatibilities between Christianity and this new trend. In this essay, having The Christian Transhumanist Affirmation as a starting point, we will try to offer a possible perspective from the point of view of Orthodox Christianity in relation to what this association claims.
SAINT BASIL THE GREAT, MASTER OF PHILANTHROPY
Authors: MUREȘAN Radu Petre
Published: August 2020

The present study aims to highlight the concept of philanthropy in the writings of Saint Basil the Great, the manner in which it was materialized during the lifetime of the Great Cappadocian Father and its relevance for the mission of the Orthodox Church in the contemporary society. Man as a social being and philanthropy as a result of the communion in love, following the Trinitarian model, are the main themes of Saint Basil’s sermons. The study shows that the philanthropy-centered discourse of Saint Basil would not have any impact if it weren’t reinforced by the personal example, when he shared all the wealth inherited from his parents with the poor, and built a whole philanthropic complex on the outskirts of Caesarea. Regarding the importance of St. Basil's writings for the current life of the Church, the study points out that St. Basil was actively involved in the life of society and tried, with audacity and perseverance, to denounce and correct its inequalities. In so doing, he proved to be a leader of the Church whose spiritual, administrative, and moral authority was so great that it could no longer be ignored or challenged by the authority of the state.
THE CHURCH IN NORTHERN NIGERIA IN THE FACE OF RELIGIOUS FUNDAMENTALISM, AND THE RE-INTERPRETATION OF THE DOCTRINE OF CHURCH SUFFERING: A REFLECTION
Authors: AKUBOR Emmanuel Osewe , AYOGU Chinedu
Published: August 2020

Extensive studies have shown that at the outset of the 21st century, the most immediate danger faced by nations of the world, apart from global climate disruption is fundamentalism. It has shown that this phenomenon has tended to divide the world on the line of religion. In the case of Nigeria, this dividing line is always in the increase and is setting people against each other. This is because, this has not only disrupted development, but has led to a situation in which some people have become second class citizens in their native country, so much so that they arguably constitute what the Catholic Doctrine refers to as the Church Suffering-faithful who are undergoing the purification of purgatory while on earth. This is hinged on the premise that perhaps for the sake of Christ and the Church, they are being prepared for heaven after torturous life on earth. The qualitative method is used for this particular research. Data obtained from primary and secondary sources were deployed to carry out the study with an analytical and narrative historical approach. This includes historical, descriptive and analytical approaches based on gathered evidence. The primary source for this research is based on field investigations conducted in the area and surrounding territories. Among other things, the data collection process includes semi-structured interviews with individuals. The research also uses historical documents from the national archives, relying on previous research conducted on issues relating to Colonial and Missionary activities in northern Nigeria, Religion, doctrine and intergroup relations in addition to documentary data taken from newspaper accounts, diaries, letters and verbal reports.
