Authors: Joseph Lewis , Kulshreshtha Prof. Neha
Published: April 2023

Abstract: The wastewater formed in various processes in the pharmaceutical industry is considered environmentally delinquent because of its unsafe and potential for influences the aquatic ecology. Pharmaceutical wastewater comprises a high volume of organic matter, expired drugs, API, etc., that causes a lot of damage to the ecology. There are still trace quantities of suspended solids and dissolved organic material, even after secondary treatment. To advance the excellence of pharmaceutical wastewater sewage, advanced treatment is vital. Catalysts contribute extremely to the industrial revolution concerning reaction rates and a decrease in manufacturing costs. Widespread research has been recognized on numerous industrial catalyses in the previous few eras. The performance of catalysts is inclined by numerous parameters, counting synthesis approaches. In this study, a heterogenous copper-based catalyst is used which is prepared via the sol-gel method to understand its performance in the treatment of pharmaceutical wastewater. The characterization of the catalyst was done by analytical techniques. The treatment of synthetic pharmaceutical wastewater was carried out at the following operation conditions: different pH, oxidant dose (H2O2) of 1 ml – 5 ml, and the absorbance of the sample was measured using a UV spectrometer. The wavelength used was from 200nm to 1000 nm.

Published: April 2023

Learning trajectory of set is a learning path to get concept of set. However, several teachers did not combine methods, approaches, and ideas in their practical deliveries. This situation becomes a concern for teachers to handle since it will affect the rule without reason so that the accepted concept will not last long in students’ memory. This study aim to describe the learning trajectory using RME models to construct the concept of set. Hypothetical learning trajectory (HLT) was designed using a qualitative method with the realistic mathematics education (RME) of Gravemeijer model as the activity stage begin from preparing for the experiment, pilot experiment, teaching experiment and retrospective analysis. The designed HLT consisted of an objective, activity, and conjecture. This study achieved an understanding of the set concept with applying RME design. By providing examples of contextual mathematics that take place in the learning environment, these outcomes were achieved. Then using media like set cards to model mathematics so that students can advance their own knowledge to the level of formal mathematics. Therefore, the RME-based HLT design can be a solution to obtain the concept of set, primarily in domain definition and set notation to produce a learning trajectory.

Mathematical literacy helps an individual recognize the role or use of mathematics in everyday life. One of the factors supporting mathematical literacy is the learning style of the student. This study aimed to describe the mathematical literacy of students in the context of SMP Negeri 1 Palopo based on their answers to PISA test questions by observing their learning styles. The subjects in this study were three eighth graders each representing visual, auditory, and kinesthetic learning styles. The data instruments used were a learning style questionnaire, a mathematical literacy test based on the 2012 PISA test draft, and an interview guide. The results of the learning style questionnaire were analyzed by referring to the indicators of the three learning styles under study, while the results of the PISA test were analyzed by referring to the indicators for each PISA level. The results of this study indicated that the visual student and the auditory student had mathematical literacy at level 3 as shown by their ability to connect and reflect things involved in interpretation and basic reasoning, while the kinesthetic student had mathematical literacy at level 4 as shown by their ability to build and communicate explanations and argumentation based on interpretations, arguments, and actions. Based on the research results, it is suggested that students be accustomed to working on PISA-like problems to improve their mathematical literacy.

In this study, We demonstrate mono and few layers MoS2 samples on the SiO2 (270nm)/Si substrate from bulk MoS2 crystal by micromechanical exfoliation technique. We also report that the Raman and PL intensity can be thermally modulated by annealing 1L, 2L and 7LMoS2 in a vacuum or air. We have systematically studied Atomic Force Microscopy, Raman and PL properties of mono and few layer MoS2 on the SiO2  (270nm)/Si substrate. First, we find that the number of layer values dependent the Raman and PL emission. First, Raman intensity area ratio of the MoS2 E12g, Ag1 and 2LA modes to that area of the Si substrate increased linear with increasing number of layers MoS2. Second, Normalized PL intensity area of the (A) peak decreased linear with increasing number of layers MoS2. The value of those graphs is a method to understand the number of layers the exfoliated MoS2. Third we found that some effects of the few layers MoS2after thermal annealed (vacuum and air 3000C for 40 min).

Effect of pulsed electromagnetic field on in vitro and in vivo neural differentiation, cell survival of human mesenchymal stem cells
Authors: U Enerelt , M Tsogbadrakh , P Jung-Keug
Published: April 2023

Low frequency-pulsed electromagnetic fields (LF-PEMFs) affect many biological processes such as differentiation, regulation of transcription factor and cell proliferation. However, the fundamental mechanisms responsible for these effects remain unclear. The aim of this study is to understand the mechanisms underlying PEMF-mediated suppression of apoptosis and promotion of survival, including PEMF-induced neuronal differentiation on in vivo and in vitro. Treatment of induced human BM-MSCs with PEMF increased the expression of neural markers such as NF-L, NeuroD1 and Tau. Moreover, treatment of induced human BMMSCs with PEMF greatly decreased cell death in a dose- and time-dependent manner. There is evidence that Akt and Ras are involved in neuronal survival and protection. Activation of Akt and Ras results in the regulation of survival proteins such as Bad and Bcl-xL. Thus, the Akt/Ras signaling pathway may be a desirable target for enhancing cell survival and treatment of neurological disease. C57B6 mice were exposed to LF-PEMF (F = 60Hz, Bm = 10mT) after photothrombotic occlusion. We measured the BDNF/TrkB/Akt signaling pathway, pro-apoptotic and pro-survival protein and gene expressions, and the expression of inflammatory mediators and performed behavioral tests in both LF-PEMF-treated and untreated ischemic stroke mice. Our analyses showed that PEMF exposure dramatically increased the activity of Akt, Rsk, Creb, Erk, Bcl-xL and Bad via phosphorylation. PEMFdependent cell protection was reversed by pretreatment with LY294002, a specific inhibitor of phosphatidylinositol 3-kinase (PI3K). Our data suggest that the PI3K/Akt/Bad signaling pathway may be a possible mechanism for the cell-protective effects of PEMF. Also results indicated that LF-PEMF treatment promotes activation of the BDNF/TrkB/Akt signaling pathway. Subsequently, pro-survival proteins were significantly increased, while proapoptotic proteins and inflammatory mediators were decreased in ischemic stroke mice after LF-PEMF treatment. The results demonstrated that LF-PEMF exposure has a neuroprotective effect after ischemic stroke in mice during the recovery process.

trap was used to sample insects in the rice field area at three
identified sites. A total of 2499 bats from 27 species were captured and
for insect abundance a total of 161,539 individuals from 11 orders were
captured. Rhinolophus pusillus was recorded as the dominant bat species
in all seasons. In the dry season, the dominant insect pest was
Chilo polychrysus (Stem borer) and in the wet season,
Nilaparvata lugens (Brown planthopper) the dominant insect pest
species. Insects from the Order Coleoptera (the dominant insect Order in
dry season) may be eaten by bats that have a larger body size and that
have a strong bite force. Due to high food availability and insect
abundance, the peak time of bat foraging activity is the same as the
peak time of insect emergence. We found that there is a significant
relationship between bat activity with temperature and rainfall, but not
with insect abundance. This study further highlights the importance of
bats in regulating the insect pests population naturally in the rice
field area.

Turquoise Management Model in Knowledge-Based Organisations
Authors: Fałda Beata , Małkowska Maria Alicja
Published: April 2023

Subject and purpose of the work

The commercial success of an organisation is based on its unique characteristics which make it stand out from its competitors. It can be the result of as many factors as there are many types of organisations and the goals they pursue. However, there are some invariants among them, which include leadership and management style associated with it. The purpose of this article is to demonstrate the possible ways of implementing the idea of a turquoise management model in organisations with strong knowledge-based leadership.

Materials and methods

The subject of the study were medical entities of the SMEs group. A faceto- face and telephone interview with a person holding a leadership role in the treatment unit was chosen as the research method.

Results and conclusions

An attempt was made to verify the thesis of the possible synergies between turquoise ideas and strong leadership. The paper demonstrates a natural evolution of the leadership model which has resulted from the generation Y and Z entering the labor market, which is characterised by features converging with the turquoise idea of management.
The Relationship Between Social Capital and Geographical Indications. A Comparative Case Study of Prosciutto Veneto Berico Euganeo PDO (Italy) and Jamón de Trevélez PGI (Spain)
Authors: Valverde Francisco Antonio Navarro , Pagliacci Francesco , Salpina Dana
Published: April 2023

This study compares two EU quality-label schemes in Italy and Spain: Prosciutto Veneto Berico Euganeo PDO and Jamón de Trevélez PGI, respectively. It aims to demonstrate that social capital plays an important role in both establishing and managing geographical indications (GIs), and that obtaining this label reinforces existing networks, so boosting rural development. The research is based on semi-structured interviews with 7 key informants, the analysis of institutional information and legislation, and of statistical data on the socioeconomic structure of both geographical areas. The research reveals two quite different experiences in obtaining EU quality labels, regardless of the fact that the products, places and people involved in this process have various aspects in common. This study illustrates how the advantages resulting from these high-quality labels and their impact on rural development can vary in relation to the level of social capital and the strength of local networks.

Authors: Vítová Blanka
Published: April 2023

Summary

The article investigates the connection between the unfair commercial practices and the concept of corporate social responsibility (CSR) from the perspective of consumer law. With the use of descriptive analysis and normative argument, it provides examples of unfair commercial practices by large enterprises within the travel sector and explains how they breach the EU legal regulation. The article concludes that the concept of CSR covers actions which go above the basic legal regulation and since the practices performed by the enterprises within the travel sector discussed in the article breach several legal regulations, they may not be presented as CSR activities.
The relations between the Singapore Mediation Convention and the European Mediation Directive
Authors: Malacka Michal
Published: April 2023

Summary

This paper deals with the Singapore Convention on Mediation from United Nations General Assembly in December 2018 and signed in Singapore on 7 August 2019. Also with the European Union situation, given by the existence of the Directive 2008/52/EC of the European Parliament and of the Council of 21 May 2008 on certain aspects of mediation in civil and commercial matters. EU States haven’t signed the Singapore Convention on Mediation. This paper is trying to analyse the two instruments, the Directive as a harmonisation instrument, maybe opening the field of the possible usage of the convention and not existing Regulation unifying the legal ground in the EU. The Singapore Convention on Mediation enters into force six months after deposit of the third instrument of ratification, acceptance, approval, or accession. EU is now in the position, where a decision about new Directive, or maybe the acceptance of the convention must be decided with accordance to all the dilemmas of the Singapore Convention.
