Published: June 2023

The processing acetone wastes method into isopropyl alcohol (ISA) by liquid-phase hydrogenation on the new catalyst obtained by the selfpropagating high-temperature synthesis (SHS) was studied. The optimal compositions of SHS for producing nickel-chromium catalysts were identified. The comparative analysis of the activity of the SHS catalyst was carried out in comparison with the traditional one obtained as a result of coprecipitation. The surface area morphology of the obtained samples was measured. The surface morphology was studied, including the calculation of the mesopores distribution. It was found that the proposed catalyst was reduced at a higher temperature than the previously proposed one. The stability of particles to sintering was confirmed.

Published: June 2023

The contribution of aerotechnogenic migration to the accumulation of heavy metals by coltsfoot in the city of Tyumen was studied. Metal content analysis (Cu, Zn, Fe, Mn, Pb, Cd, Ni, Co, Cr) was performed using atomic absorption and atomic emission spectroscopy. The conclusion was made about the metal absorption from the soil by the plant root system and the presence of non-root intake of metals from the atmosphere. The interlinkage of aerotechnogenic migration with the metal volatility and the aerosols stability was revealed.

Authors: Amahalu Nestor Ndubuisi , Charles Okudo Chibuike , Eyide Michael Ugeoritsete
Published: June 2023

This study assessed the determinants of cash holdings of quoted pharmaceutical firms in Nigeria from 2014-2022. Three hypotheses were formulated in line with the objectives of the study. Ex-post facto research design and panel data were adopted and the data for the study were obtained from fact books, annual reports and account of the quoted pharmaceutical firms under study. Pearson coefficient of correlation and Panel least square regression were applied for the test of the three hypotheses formulated with aid of E-View 9.0 statistical software. Findings showed that market-to-book value ratio, investment in non-current assets and cash flow have a significant but negative significant relationship with cash holding (proxied by cash and cash equivalent) at 5% significant level. Based on these findings, the study recommended among others that pharmaceutical firms should adopt cash management practices since cash reduces the burden to perform well and allows managers to invest in projects that best suit their own interests.
Metodologia para Estimativa de Perdas em um Conversor Buck Síncrono com Semicondutores de Nitreto de Gálio
Authors: Barboza Igor B. , Grassi Giulia K. , Duarte Renan R. , Menke Maikel F. , Costa Marco A. Dalla
Published: June 2023

Neste artigo, uma nova proposta de metodologia para estimativa de perdas em conversores que empregam transistores GaN do tipo Intensificação (eGaN) é apresentada. A metodologia proposta apresenta como diferenciais, em relação aos demais trabalhos existentes na literatura, dois pontos principais. O primeiro deles é a consideração do efeito das temperaturas medidas nos transistores GaN e nos elementos magnéticos, relacionado às perdas nestes elementos. A outra contribuição é uma estimativa de perdas como uma alternativa para os desafios de medição de tensões e correntes nos transistores GaN, incluindo menores diferenças entre as perdas estimadas e experimentais do conversor, em diversos pontos de operação. Para a validação da metodologia proposta, dois estudos de caso que utilizam dispositivos GaN em um conversor Buck Síncrono foram implementados. O primeiro estudo de caso faz uso de uma solução monolítica com transistores eGaN e o segundo estudo de caso utiliza uma solução discreta de transistores GaN. Por fim, por meio da aplicação do modelo de estimativa de perdas desenvolvido nos estudos de caso 1 e 2, obtiveram-se erros de 0,034% e 0,122%, respectivamente, entre os valores estimados e os valores medidos, em potência nominal.

Published: June 2023

BACKGROUND:Globally, the incidence of neonatal sepsis is estimated to be 2,824 per 100,000 live births, of which 17.6% of neonates have died. The incidence of sepsis was high among premature neonates (10,252 per 100,000 live births). Data on the association between vaginal examinations during labor and neonatal sepsis among preterm neonates in Ethiopia are sparse. This study aimed to assess the prevalence of neonatal sepsis and its associated factors among preterm babies in southern Ethiopia.

METHODS:An institution-based cross-sectional study was conducted among 291 preterm neonates from May 1 to August 30, 2021. Data were collected using a pretested structured questionnaire. Data were entered into Epi Data 3.1 and exported into SPSS version 20 for analysis. We summarized participant characteristics using proportions and means. Factors associated with neonatal sepsis were analyzed using binary and multivariable logistic regression with an adjusted odds ratio (AOR) and 95% confidence interval (CI). Ap-value of <.05 was a cutoff point to declare a statistically significant association.

RESULTS:Overall, the prevalence of neonatal sepsis was 52.9% (95% CI: 46.2, 54.4) among preterm neonates. Performing vaginal examinations frequently during labor significantly increases the likelihood of developing neonatal sepsis (AOR: 7.45, 95% CI: 3.87, 6.79). In addition, premature rupture of the membranes (AOR: 5.79, 95% CI: 6.769, 10.65) and the 5-minute Apgar of less than 7 (AOR: 1.780, 95% CI: 2.507,6.094) were associated with neonatal sepsis.

CONCLUSIONS:In this study, the prevalence of neonatal sepsis was high among preterm babies. Performing vaginal examinations frequently in labor increases the risk of preterm babies developing neonatal sepsis. Limiting the frequency of vaginal examinations during labor and good aseptic technique while performing vaginal examinations are vital to reduce the risk of developing neonatal sepsis.
In search of a queer pathos: Connections between Aby Warburg and Queer Studies
Authors: Marconi Dieison , Machado Ramos de Almeida Gabriela
Published: June 2023

The paper investigates connections between queer studies and the contributions of Aby Warburg to image theories, specifically the notion of time as a fundamental conceptual operator in the work of Warburg and his main exegete, Georges Didi-Huberman, from whom we sought help in the endeavor of envisioning a queer pathos that would survive in visual culture. Time is also at the core of a certain criticism by some authors of queer studies to the notion of chrononormativity as biopolitical regulation. This paper attempts to understand how Warburgian notions of Nachleben and Pathosformel help to investigate how abject and anachronistic gestures which keep reappearing as a queer symptom in culture, disorganizing a “natural model” of history of art and breaking with the history of progress that organizes relations between gender, body and sexuality according to disciplinary temporal schema.
Les enjeux de l’évaluation et de la gouvernance des chaînes de valeur agricoles – Exemple de la mangue au Burkina Faso
Authors: Parrot Laurent , Biard Yannick , Klaver Dieuwke , Kabré Edit , Vannière Henri
Published: June 2023

L’évaluation intégrée des filières agricoles par des analyses économiques, sociales et environnementales a pour finalité de fournir les informations nécessaires et suffisantes pour orienter ou appuyer les décisions d’investissement dans le cadre d’un développement durable. Ces évaluations s’appuient d’une part sur des collectes de données et des analyses sur l’organisation de ces filières et, d’autre part, sur la stratégie de leurs acteurs. L’accès aux informations, leur fiabilité, ainsi que le contexte général dans lequel ces filières évoluent sont des dimensions essentielles. Le contexte peut rendre difficiles les décisions d’investir et la mise en œuvre de politiques sectorielles agricoles. En effet, investir nécessite une confiance en l’avenir car cela implique un endettement, donc une prise de risque et une responsabilité. Afin d’atténuer ce risque, l’investisseur a besoin d’informations et doit pouvoir y accéder. Dans les pays à faible revenu, les difficultés à appliquer des textes réglementaires et l’absence d’informations fiables compliquent le développement de chaînes de valeur agricoles durables, ainsi que les démarches pour les évaluer. Nous montrons comment les chaînes de valeur de la mangue au Burkina Faso sont concernées.
The challenges of agricultural value chain assessment and governance – The example of mangoes in Burkina Faso
Authors: Parrot Laurent , Biard Yannick , Klaver Dieuwke , Kabré Edit , Vannière Henri
Published: June 2023

The integrated assessment of agricultural value chains through economic, social and environmental analyses is aimed at providing the necessary and sufficient information to guide or support investment decisions in the context of sustainable development. These assessments are based on data collection and analyses of the organisation of these value chains, as well as on their stakeholders’ strategies. Access to information, the reliability of this information, and the general context in which these value chains evolve are key dimensions. The context can be an obstacle to investment decisions and the implementation of sectoral agricultural policies. Indeed, investing requires confidence in the future, since it implies debt, and therefore risk-taking and accountability. In order to mitigate this risk, investors require information and must be able to access it. In low-income countries, difficulties in applying regulatory texts and the lack of reliable information hamper the development of sustainable agricultural value chains, as well as the processes to assess them. We show how mango value chains in Burkina Faso are concerned.

Challenges of newspaper reportage of the Niger Delta conflict: reporter’s perspectives of the insurgency
Authors: O.O. Ofem
Published: June 2023

The paper assessed the viewpoints of reporters on the challenges of newspaper reportage of the Niger Delta conflict in Nigeria (2006-2007). The Guardian, The Vanguard and The Niger Delta Newspapers were purposively selected for the study due to both their national and local outlooks in the coverage and reportage of the conflict. In-depth interviews were conducted on two (2) correspondents each from the three (3) selected newspapers making a total of six (6), while four (4) respondents from each of the newspaper making 12 were selected for questionnaire administration. Results obtained identified ownership (41.7%) and media protective interest (33.3%) as the primary challenges faced by the media in the reportage of the Niger Delta conflict. The actions of the Ijaw Youths, militant activities (41.7%), killings (25%) and hostage taking (16.6%) considerably affected the nature of reportage during the heat days or periods of the conflict. Findings from the in-depth interviews showed that the geology (nature of terrain) of the conflict area, issue of trust from the militants and security forces exerted considerable influence on the selected newspapers failure to perform the required effective mediation and intervention role in the conflict.
Participatory Development Communication in Mitigating Forest and Land Fires in Riau Province
Authors: Widhagdha Miftah Faridl , Purwanto Wahyu , Hidayat Rahmad
Published: June 2023

This study examines CSR programs for mitigating forest and land fires in Riau Province carried out by the private sector, namely PT Pertamina Refinery Unit II Sungai Pakning through a participatory development communication approach. This research was conducted in the community assisted by CSR of PT Pertamina (Persero) Refinery Unit II Sungai Pakning located in Sungai Pakning Village, Bukit Batu District, Bengkalis Regency, Riau Province. This research method uses qualitative methods by collecting data through participant observation. The results of this study indicate that the participatory development communication approach carried out by PT Pertamina (Persero) Refinery Unit II Sungai Pakning CSR in carrying out forest and land fire mitigation activities is carried out through four stages of participatory communication namely heteroglosia, polyphony, dialogue and carnival. These four stages of participatory communication are supported because of the still close communitarian tradition and the enactment of deliberative communication in the decision-making process at the local level. In this study it was also found that the role of local leaders as opinion leaders was still needed in conveying important information. The role of local leaders is not merely an informal symbol, but also an influential party in determining the diversity of the community, mediators in public discussions and dialogues, and guards of local customs that are still held by the community. Therefore, the participatory communication approach based on the four characters mentioned earlier is important to involve the role of local leaders so that the messages communicated can be more optimal. Keywords: CSR, Development Communication, Participatory Communication
Tartu-Moscow Semiotic School and the Development of Semiotic Studies in Indonesia
Authors: Nazaruddin Muzayin
Published: June 2023

This paper proposes the importance of the infusion of Tartu-Moscow Semiotics School (TMSS) into the development of semiotic studies in Indonesia. Semiotic studies in Indonesia have mostly departed from the ideas of Peirce, Saussure, and Barthes, while TMSS has not been recognized by Indonesian scholars. The paper proposes two concepts of TMSS, namely ‘text’ and ‘semiosphere’, which would significantly enhance semiotic studies in Indonesia. Indonesian scholars usually regard text as a concrete artefact, causing overgeneralization that every artefact is text, as well as oversimplification that every text is concrete artefact. Semiotic studies in Indonesia tend to exclude text as the object study from its cultural context and to analyse it in its individuality. While, TMSS defines text based on its meaningfulness, authority, and cultural functions. Besides its function as message carrier, TMSS proposes three functions of text, namely creative, poetic, and memory functions. These functions are connection points between a text and its wider cultural and historical contexts and its dynamic aspects. Finally, the concept of semiosphere, an abstract model in which semiosis occurs and outside of which semiosis cannot exist, would drive a holism perspective, avoiding the tendency to analyse the discrete text in its individuality.Keywords: Tartu-Moscow Semiotic School; text; text function; semiosphere; sign system.

Published: June 2023

The purpose of this study is to examine public engagement with the hashtag #CampurLGBT campaign as portrayed by Malaysian netizens’ response on social media. This study applies AIDA model, consisting of four levels, namely attention, interest, desire, and action. Netizens’ response to the campaign, such as their comments, discussions, and even pictures posted under the hashtag #CampurLGBT are analyzed, in order to understand public engagement with the issue, also to determine how the campaign may influence their views on the LGBT lifestyle. This study finds that despite the campaign being successful in recruiting followers and supporters of the movement, the number of those supporting it is relatively small compared with those who are against it. Those who respond positively to the campaign are mostly members of the LGBT community itself, also urban Malaysian netizens who have been exposed to the LGBT culture through friends and family members. While the netizens who have shown their negative responses are mostly concerned with the practice of being prohibited in Islam, also with the negative health implications of the LGBT lifestyle. They feel attacked by the ‘negative messages’ of the campaign, and therefore need to do the counter campaign. They explicitly declare their negative desire towards the campaign, also take action to reject the campaign.Keywords: public engagement; AIDA model; #CampurLGBT; #TolakLGBT.
Nationalism in Popular Culture: Critical Discourse Studies on American and Indonesian Films
Authors: Felani Herman , Adi Ida Rochani , Lukito Ratno
Published: June 2023

Many scholars have alarmed the rise of new extreme nationalism in many countries which is actively  promoted by some important national and international leaders. This paper examines the discourses of nationalism in popular culture and compares them with the nationalism ideas as promoted by those political leaders. Assuming that popular culture represents the bedrock belief of the society, this study has investigated the ideology of nationalism in 10 American and 10 Indonesian films applying the discourse historical approach from Ruth Wodak and Martin Reisigl. This study has identified nine features of nationalism in American films, i.e. us against them, saving life of Americans versus taking life of enemies,  individual versus institutional hero, hero as common people, anti war narratives, individual versus national interest, absence of governmental supports, white as the dominant, and superpower. While six main features of nationalism in Indonesian films are against poverty, against foreign power, against corruption, sacrifice and service for the nation, imagination as a nation, and developing the nation. This study concludes that the discourse of nationalism in American and Indonesian films do not in line with the nationalism ideas as proposed by the politicians or the government. While the politicians are campaigning new hostile nationalism, popular cultures are promoting nationalism with individual freedom and equality, striving for prosperity, and fighting poverty.Keywords: Discourse-Historical Approach; nationalism; new nationalism; popular culture; American film;   Indonesian film.
Telegram Discourse on The 2017 Iran’s Presidential Election
Authors: Kermani Hossein
Published: June 2023

This paper explores the discourse in Telegram during the Iran’s 2017 election period. Recently, Telegram has become the most popular social media in Iran, playing a significant role in recent social and political events. This paper examines the highest-ranking posts to provide a better understanding of Telegram posts’ characteristics, dynamics, and potentials for producing the new discourses or reinforcing the existing ones. The materials of this study were gathered from the 620 most-viewed posts during the election period. The data were analyzed mainly with quantitative content analysis and completed with ethnographic content analysis. This study finds that counter discourses are not shaped in Telegram and the most viewed posts mainly reproduce and reinforce the dominant discourses. This finding also clarifies how the content circulation is affected by the national political events, such as the election.  Keywords: Telegram, Iran, presidential election, content analysis, discourse analysis.
Mediating Indonesian Islamic Center in the Era of Post-Islamism
Authors: Hidayaturrahman Purnama , Dhona Holy Rafika
Published: June 2023

Islamic centers emerged when Muslims in the West had difficulties to build a mosque. As a majority, Indonesian Muslim communities do not need to adopt the concept of Western Islamic Center.  Nevertheless, establishing Islamic Center is quite popular among Indonesian Muslims. This paper argues that the establishment of Islamic Center is a practice of post-Islamism in Indonesia, in which Islam is interpreted in a specific way that juxtaposes religiosity and leisure, mixes between ‘the sacred’ and ‘the profane’. Taking the Mataram Islamic Center as a case study, this study explores how discourse of the Islamic Center shapes its establishment. Applying critical discourse analysis, this study takes several units of analysis, i.e. the mediation practices of the center and the visiting practices of the visitors. This study finds that there are two prominent discourses, namely the center as a religious space and the center as a tourist space, both of which do not defeat each other. Keywords: Islamic center, critical discourse analysis, post-Islamism, space mediation.
Tsunami in the Collective Memory: A Reception Study of the Visitors of Tsunami Memorials in Aceh, Indonesia
Authors: Nazaruddin Muzayin , Indah Lana Senja
Published: June 2023

Disaster tourism could be defined as tourism practices based on certain disasters, both natural and cultural, which happened in the past. It melts the enjoyment and trauma, when people come and enjoy the monument of disaster or damaged place caused by a disaster. Thus, many questions arise: why do people come as tourists to disaster artefacts? How do people make meaning of the disaster artefacts? The paper examines this question, taking the visitors of Tsunami Museum, PLTD Apung Monument, and Kapal Tsunami Lampulo as study cases. The paper aims to describe the meaning of disaster tourism activities constructed by the visitors of these three memorials. The broader purpose of the study is to understand why and how people enjoy the disaster tourism destinations. The paper is based on qualitative research done in these three memorials in Aceh, Indonesia. The fieldwork to collect primary data was conducted in three months in 2015 and another three months in 2017, optimizing in-depth interviews and observations. The study concludes that disaster tourism activities are closely related to individual and collective memory. The Acehnese or the outsider, who is deeply related to the place or has direct experience of the tsunami, construct the meaning of their activities as remembering and recreational activities, which is closely associated with their inner level of memory. While the Indonesian and foreigners who do not have firsthand experience of the disaster construct the meaning of their visits as educational and recreational activities, which is related to the collective memory of the 2004 tsunami. Thus, the study confirms some previous studies that have emphasized that disaster tourism could have different roles and change its function to suit visitors' needs. Keywords: disaster tourism, collective memory, Tsunami Museum, PLTD Apung Monument, Kapal Tsunami Lampulo
Islamic Discourse and Baduy in Tanah Ulayat Kanekes: Contestations and Connections
Authors: Naziah Salma Qowiyatun , Dhona Holy Rafika
Published: June 2023

The Cicakal Girang village, known as the village where the Muslim Baduy lives, has different religious practices from the Baduy. Obedience to Baduy customs is very loose in this village, which the Baduy indigenous community permits. This study investigates the cultural discourse producing the Cicakal Girang village and the reproduction of such discourse as well. The empirical data were collected through fieldwork and analyzed with the cultural discourse analysis method. This study finds that the Cicakal Girang and its Islamic activities practice the existing discourse system, namely the Cicakal Girang as a place of the 'penghulu ratu’ (the queen) of the Baduy community. Such discourse situates the Cicakal Girang as a connection space for the Baduy community with the outside world. It is reproduced in the interaction between Cicakal Girang and the Baduy community. Keywords: Baduy, Cicakal Girang, communication geography, cultural discourse analysis
“They Are Not Gone – yet!” : Social Media Users’ Reaction to the Perceived Death of Cyber Acquaintances
Authors: Memarian Mohammad
Published: June 2023

Through in-depth interviews with 28 Iranian social media users, this paper examines the reaction of social media users to the perceived death of their online friends in order to find common threads of anxieties and uncertainties among users who experienced such events. We found that subjects experience contextual, cognitive and emotional difficulties in absorbing the news, leading them to go through an initial stage of wandering before dealing with the actual trauma. Such difficulties are categorized in terms of 5 generic conditions: Conceptual Dilemma, Rational Denial, Situational Puzzlement, Relational Confusion, and Environmental Inconsistency. With ample examples, we have discussed each condition and their interrelatedness. It seems that rather than an absolute fact, the death of an online friend is understood, or felt, as a fuzzy state of mixed presence and absence, in relation to which later death events in online or even offline situations may be understood.
Leveraging Pan-Africanism to Fight French Neocolonialism in Francophone Africa: A Study of the Cameroonian Audio-Visual Media and Intelligentsia
Authors: Endong Floribert Patrick C.
Published: June 2023

The persistence of French neo-colonialism has motivated the emergence of new and very aggressive forms of pan-Africanism in most – nay all – Francophone African countries. Indeed, many Francophobic pressure groups operating in Francophone African countries have sought to resist French neo-colonialism in their countries by mobilizing forms of pan-Africanism, which to a great extent, are xenophobic and disruptive to France’s diplomacy in specific Francophone African countries. In Cameroon, for instance, several so-called pan-African media initiatives, such as Afrique Media, have resorted to a very combative – but professionally problematic – form of journalism called ‘journalism of opinion’ to denounce Western political imperialism and contribute in no small measure, to the fight against Western (and particularly French) neo-colonialism in Cameroon. This paper seeks to illustrate the above phenomenon hinging on secondary sources and critical observations. Specifically, the paper explores indexes of French neo-colonialism in Cameroon and examines how the Cameroonian intelligentsia, in general and specific pan-African media houses in the countries in particular, have sought to combat this French neo-colonialism.

Published: June 2023

Introduction: CT scan of the skull in patients with head trauma play an important role in identifying patients' injuries; In moderate to severe brain injury; CT scans are arguably the best way to get information about the intracranial complications of a head injury. Researchers have cited a number of reasons for why doctors are increasingly asking for CT scans of patients. In this study; pathological findings in CT scan of patients with mild cranial trauma and level of consciousness 13-15 are examined.

Method: In this study, the treatment process of 445 patients who had referred to the emergency department due to skull trauma was examined as research units; and samples were taken by simple random sampling among patients for whom CT scan of the brain was requested. In this study; the reasons for requesting a CT scan of the skull from the requesting physician were questioned through an interview at the time of request.

Results: According to the tables; it can be seen that most of the patients referred to the hospital due to skull trauma for CT scan were men and were discharged in less than the first 24 hours. The age group of 21 to 30 years had the highest and the age group over 70 years had the lowest frequency and the highest percentage of request for CT scan was by doctor and the biggest injury that caused patients with mild cranial trauma to go to hospital was fall.

Conclusion

Based on the findings of this study, cranial trauma is one of the life-threatening factors that can cause minor or severe injuries Its range varies from superficial injuries to hematoma and intracranial hemorrhage, which is a reason to perform CT scans of patients with skull trauma. In order to carefully examine the extent of the damage to the patient and to avoid possible risks and to take the necessary measures for treatment. On the other hand, the lack of clear protocols as well as the lack of clarity and certainty of physicians in their diagnoses to perform graphs of qualified people has increased the number of unnecessary CT scans

Numerical Solutions for the Nonlinear PDEs of Fractional Order by Using a New Double Integral Transform with Variational Iteration Method
Authors: AL-Safi Mohammed G. S. , Fawzi Rand Muhaned , AL-Hussein Wurood R. Abd
Published: June 2023

This paper considers a new Double Integral transform called Double Sumudu-Elzaki transform DSET. The combining of the DSET with a semi-analytical method, namely the variational iteration method DSETVIM, to arrive numerical solution of nonlinear PDEs of Fractional Order derivatives. The proposed dual method property decreases the number of calculations required, so combining these two methods leads to calculating the solution's speed. The suggested technique is tested on four problems. The results demonstrated that solving these types of equations using the DSETVIM was more advantageous and efficient
Assessing the Activity of Renin and GST in the Serum of Ladies Suffering from Polycystic Ovary Syndrome and COVID-19 to Predict the Danger of Cardiac Disease
Authors: Ali Shaimaa Emad , Khaleel Fayhaa M.
Published: June 2023

The coronavirus-pandemic has a major impact on women's-mental and physical-health. Polycystic-ovary-syndrome (PCOS) has a high-predisposition to many cardiometabolic-risk factors that increase susceptibility to severe complications of COVID-19 and also exhibit an increased likelihood of subfertility. The study includes the extent of the effect of COVID-19-virus on renin-levels, glutathione-s-transferase-activity and other biochemical parameters in PCOS-women. The study included 120 samples of ladies that involved: 80 PCOS-patients, and 40 healthy-ladies. Both main groups were divided into subgroups based on COVID-19 infected or not. Blood-samples were collected from PCOS-patients in Kamal-Al-Samara Hospital, at the period between December until June. Some biochemical parameters were measured for all study-groups, which included: determination of serum renin levels by using the ELISA-technique, GST-activity, lipid-profile.  FBS was assessed manually, and hormones were assessed using VIDAS-analyzer-hormones. The result showed a possible relationship between FBS-levels and renin in PCOS-ladies (Stein-Leventhal-Syndrome), while GST-activity were inversely associated with BMI in PCOS-ladies. Also, it was found that the renin-levels were higher in PCOS-patients groups compared with healthy-groups. On the other hand, the renin levels and Glutathione-S-Transferase-activity were lower in PCOS-patients-infected-with-COVID-19 than female-patients-without-COVID-19. The statistical-data-displayed that the level of renin is associated negatively with glutathione-s-transferase-activity in PCOS-cases. Renin level was higher in PCOS-ladies, this may lead to increase renal-dysfunction and risk of cardiovascular-disease that may be expected in patients. A decrease in the antioxidant-capacity may be because the high number of free-radicals that enter the body by the virus and high levels of renin which lead to a higher risk of PCOS-complication like cardiovascular-disease.

In this study, an improved process was proposed for the synthesis of structure-controlled Cu2O nanoparticles, using a simplified wet chemical method at room temperature. A chemical solution route was established to synthesize Cu2O crystals with various sizes and morphologies. The structure, morphology, and optical properties of Cu2O nanoparticles were analyzed by X-ray diffraction, SEM (scanning electron microscope), and UV-Vis spectroscopy. By adjusting the aqueous mixture solutions of NaOH and NH2OH•HCl, the synthesis of Cu2O crystals with different morphology and size could be realized. Strangely, it was found that the change in the ratio of de-ionized water and NaOH aqueous solution led to the synthesis of Cu2O crystals of different sizes, while the morphology of Cu2O crystals was not affected. The synthesized Cu2O crystal samples were used as photocatalysts for methyl orange (MO) dye decomposition, as a model molecule, to evaluate the photocatalytic activities. However, under 200 watts of a visible light source, there are four samples with and without graphene-based nanocomposite of Cu2O NPs. The results showed that, compared with roughly spherical, irregular but thick plates, brick and small granule spheres shaped Cu2O nanoparticles provided better activity. The Cu2O sample with irregular but thick platelet-like shapes, having an average particle size of 0.53 µm, exhibited excellent photocatalytic activity (99.08% degradation). In addition, by reducing the size of Cu2O particles and preparing their graphene composition, one can fabricate a sample (Cu2-Cu2Gr) with the highest efficiency which has significantly better photocatalytic activity in comparison to the others. This work represents an innovative strategy for pre-the-case production of nanomaterials with shapes and sizes, that is, Cu2O crystals, with excellent photocatalytic activity through compositing with graphene

Despite improvements in the detection and treatment of severe mental disorders, suicide remains a significant public health concern. Suicide prevention and control initiatives can benefit greatly from a thorough comprehension and foreseeability of suicide patterns. Understanding suicide patterns, especially through social media data analysis, can help in suicide prevention and control efforts. The objective of this study is to evaluate predictors of suicidal behavior in humans using machine learning. It is crucial to create a machine learning model for detection of suicide thoughts by monitoring a user's social media posts to identify warning signs of mental health issues. Through the analysis of social media posts, our research intends to develop a machine learning model for identifying suicide ideation and probable mental health problems. This study will help immensely to comprehend the environmental risk factors that influence suicidal thoughts and conduct across time. In this research the use of machine learning on social media data is an exciting new direction for understanding the environmental risk factors that impact an individual's susceptibility to suicide ideation and conduct over time. The machine learning algorithms showed high accuracy, precision, recall, and F1-score in detecting suicide patterns on social media data whereas SVM has the highest performance with an accuracy of 0.886.

The demand for article publication among students has intensified in various universities. However, these demands lead to plagiarism behavior, so journalistic ethics education at the beginning of college entry needs to be socialized early. This research is the result of field research. Analysis of research data from interviews, observations, and documentation with the reduction, display, and verification stages. Journalistic fiqh, as the ethical basis for students of the Miftahul Ulum Lumajang Syari'ah College of Sciences, carries out ethical principles based on Islamic teachings; among others, in carrying out journalistic duties and publishing articles, they should convey information based on facts that can be confirmed, because if they manipulate research results It is the same as guarding against spreading false news or hoaxes, so that provoked parties to appear, and more importantly, not accessing pornographic websites and not using social media to sell prohibited items.

A Semi-Supervised Domain Adaptive Learning Approach to Unstructured Road Region Semantic Segmentation for Greenhouse Robots

Published: June 2023

Efficient drivable region segmentation is a critical for greenhouse robot navigation. State-of-the-art deep learning based road segmentation methods rely largely on labeled datasets to deal with the complexity of unstructured facility agriculture environment. However, the scarcity of annotated datasets limits the model performance. To break the bottleneck, this paper proposes a semi-supervised domain adaptive learning method for unstructured road semantic segmentation. Firstly, we establish a training framework for segmentation models through the transfer learning approach from a synthetic road dataset to an unstructured road dataset. Secondly, we determine the optimal pre-training strategy for solving the greenhouse road segmentation problem. Finally, for the long-tailed distribution of image data in the process of drivable area segmentation, we optimize the loss function to obtain an effective segmentation model for greenhouse robot navigation. For unstructured facility farming scenarios, we created an unstructured road dataset with annotation. Experiments show that, with a small number of labeled data, the road mIoU reaches 98.6%, which is about 10% greater than the existing unstructured road segmentation models to deal with ambiguous boundaries, complex obstacles, and shadow interference. It shows that the proposed method is feasible to leverage the successful existing city self-driving models and datasets to enrich and improve the road segmentation under agricultural scenarios.
Human Capital and Gender Wage Inequality in Sub-Saharan Africa: Evidence from the Quantile Model with Smoothing Instrumental Variables

Published: June 2023

The objective of this study is to determine the conditional impact of human capital on gender wage inequality in sub-Saharan Africa. We use a sample of 30 countries between 1995 and 2015. Moreover, we consider the quantile model of instrumental variables of Chernozhukov and Hansen (2008); while using the Kaplan (2022) estimator. Next, human capital is measured by the Barro and Lee (2015) indicator, which determines the educational attainment of women aged 15–64. The estimates show that human capital reduces gender inequality in all quantiles in Sub-Saharan Africa (lower quantile 0.25; middle quantile 0.5 and upper quantile 0.75). Moreover, when analyzed by subregion, only the lower (0.25) and middle (0.5) quantiles in Central Africa show an increase in the gender wage gap. Furthermore, using the Peen World Table indicator as a measure of human capital, the results obtained confirm those obtained by Barro and Lee (2015). To check the robustness of our results, we used two-stage least squares estimation, two-stage generalized moments in system, and simultaneous quantile regression. The results are consistent with those obtained using the Kaplan quantile estimator (2022) for instrumental variable smoothing.
