A green HPLC method for the determination of torasemide in pharmaceutical dosage forms: Development, validation, and greenness assessment
Authors: Akbel Erten , Bulduk İbrahim , Gökçe Süleyman
Published: November 2023

Two HPLC methods were developed for the determination of torasemide in pharmaceutical products. In the first method, a C18 column whose temperature was kept constant at 25 °C was used. A combination of 0.1% formic acid solution in water and acetonitrile (50/50, v/v) was used as the mobile phase, and isocratic elution was performed at a flow rate of 1.0 mL min-1. Detection was carried out at 288 nm using the UV detector. Although all other conditions are the same as in the first method, the only difference in the second method is that ethanol is used instead of acetonitrile as the organic modifier in the mobile phase. HPLC methods were validated in accordance with ICH guidelines. Correlation coefficients were greater than 0.999 in the concentration range of 5-30 mg mL-1. Later, HPLC methods were applied to pharmaceutical formulations. Results were compared using the student (t) test for means and the Fischer (F) test for standard deviations. No significant differences were observed between methods. Additionally, a greenness evaluation of the developed methods was carried out using AGREE software. As a result, the latter method was proposed as an excellent eco-friendly alternative for the determination of torasemide in pharmaceuticals.

Authors: Wakuma Gadisa , Ele Yaya Estifanos , Getachew Negash , Megersa Negussie
Published: November 2023

In this study a dispersive liquid-liquid micro-extraction (DLLME) method was utilized for extraction of trace pharmaceuticals in wastewater samples. Factors influencing the extraction performances were tested and accordingly 900 µL dichloroethane as the extraction solvent, 1400 µL acetonitirle as dispersive solvent, 10 min extraction time at 4000 rpm centrifugation, and pH 5 were found optimum. Acetonitrile and 0.2% formic acid in water were used as eluent. The column temperature was maintained at 25 °C and the optimum detection wavelengths of 273 nm for sulfamethoxazole and 280 nm for ciprofloxacin were used. For both the analytes, the coefficients of determinations (r2) were found to vary from 0.9989 to 0.9997, confirming good linearity in the concentration range of 0.005-100 µg mL-1 for sulfamethoxazole and 0.01-100 µg mL-1 for ciprofloxacin. The LOD and LOQ were in the range of 0.78-1.58 ng mL-1 and 2.24-5.28 ng mL-1, respectively; the RSDs were 0.41-3.21% for intra-day precision and 0.37-6.44% for inter-day precision. The concentrations of the three pharmaceuticals determined ranged from 0.76-1.53 μg mL-1 in the wastewater samples collected from Black Lion Hospital. However, ciprofloxacin and doxycycline were not detected and only low concentration of sulfamethoxazole was detected in the wastewater samples collected from Menelik II Hospital.

Published: November 2023

This study investigated the effects of leaf protein concentrate (LPC) of Eremomastax speciosa (Hochst.) Cufod on some haematological and serum profile of 45 male Sprague-Dawley rats divided into nine groups of five rats per group. The rats received fresh drinking water daily, with feed at 85% of ad-lib. The standard haematinic used was Ranferon-12®, at the dose of 0.3ml/kg body weight. The resultant groups were; Group1 (Positive control, received commercial feed) Group 2 (phenylhydrazine only or negative control), Group 3 (anaemia +haematinic), 4, 5 and 6 (anaemia +100 mg/kg, 200 mg/kg and 400 mg/kg of LPC respectively), Groups 7, 8, 9 (Untreated (or UT) +100 mg/kg, 200 mg/kg and 400 mg/kg of LPC respectively). The LPC was administered orally to the designated groups, while the controls received distilled water in place of the LPC. Anaemia was induced by intraperitoneal injection of phenylhydrazine at 40 mg/kg for 2 days. Samples for haematological and biochemical analysis were collected on days 9, 21 and 28 of the experiment. Results showed that the groups supplemented with LPC were better in terms of the haematology and serum biochemical values compared to the negative control, and this strongly supported the traditional use of E. speciosa leaf in the treatment of anaemia.
Management of human resource records to support functions in the Ministry of Health, Kenya
Authors: Sudhe Aloice Olali
Published: November 2023

The study aimed to assess the management of human resource records in the Ministry of Health in Kenya. Despite the support provided by human resource records for service delivery in the Ministry, there are still challenges created by reports of missing files and accumulation of files with no space for accommodation. Problems faced by human resource records management include lack of skills and competencies, inadequate human and financial resources, and lack of policy and support by management in providing necessary requirements for the human resource records management unit’s (RMU) operation. The paper assesses the management of human resource records and proposes strategies and intervention measures for their effective and efficient management. The study adopted both the records life cycle model and qualitative research method. Stratified random sampling and purposive sampling were used to select respondents. Ten individuals from the sampled staff were selected for the pilot of the research instruments to test validity and reliability. The targeted population for the study was 307 staff from the Ministry of Health headquarters and its affiliate departments. A sample size of 94 members of staff, constituting 30% of the targeted population, was derived. They included top management, records management staff, clerical staff, human resource management staff, finance staff, information and communication technology (ICT) staff, and heads of departments. The findings revealed that despite efforts made to adopt the best practices, there were still challenges in implementing the elements of records management infrastructure, inadequate top management, and sustainable technical support in the implementation of ICT and human resource records management programmes in the ministry. The study recommended implementation of the elements of records management infrastructure, inadequate top management, and sustainable technical support in the implementation of ICT in resolving the challenges in the management of human resource records in the Ministry of Health.
Records management practice to support patients’ treatments in selected public clinics of Mankweng in Limpopo Province, South Africa
Authors: Ramaphoko Linkie M , Makgahlela Lefose
Published: November 2023

This study assessed records management practices to support patients’ treatments in the selected public clinics of Mankweng, Limpopo Province, South Africa. In primary healthcare facilities, patient records management begins during the creation stage, when a patient arrives and a file is created before treatment can be offered. Depending on the records’ value, the opened file should be managed for as long as the patient receives treatment, longer. Failure to access or retrieve the file may have a negative impact on the continuity of the patient’s treatment and progress because there will be no baseline comparison for healthcare practitioners to work on. A quantitative descriptive research design was used to collect data, and a structured questionnaire was administered to 41 participants from eight of Mankweng's 21 public clinics, including registry clerks, administrative clerks, data capturers, and healthcare workers. The collected data were analysed using descriptive statistical data analysis. According to the findings, records were created both manually and electronically and were filed daily before the end of business. Furthermore, public clinics separated active and inactive records to improve retrieval efficiency, and a functional file plan was implemented to ensure that records personnel did not have difficulty in retrieving files. The study recommends that a hybrid system be used to capture records as well as manage and control them throughout their life cycle. This will serve as a backup to prevent service disruptions if the system becomes dysfunctional, such as during blackouts or when a physical file is misplaced. The paper provides valuable information about the state of records management practices in clinics in Limpopo Province.

Published: November 2023

The phosphate sorption capacity regulates principally the phosphorus concentration and available phosphorus in any soil solution. This work aims to study the phosphate sorption characteristics of five agricultural soils in Akwa Ibom State, Nigeria. The phosphate adsorption isotherm was obtained by shaking each soil sample with 20, 40, 60, 80, 100 and 120 mgL–1 for 24 h with 20 mL of KH2PO4 in 0.01 M CaCl2 solution. The Langmuir, Freundlich, Van Huay and Temkin isotherms were applied to study the PO43-sorption characteristics of the soil samples. The Freundlich model provided the best choice for phosphate sorption with mean R2 value of 0.9872. Results obtained for the phosphate sorbed (µg g–1soil) with 120 mgL-1 solution, heterogeneity factor of adsorption sites (nF), and the Freundlich constant (KF) (Lg–1) were 101(84.3), 0.515 and 7.355 for Onna soil; 62.8(52.3), 0.641 and 2.464 for Ikot-Amama 2; 60.6(50.5), 0.708 and 3.985 for Ogu-Itumbonuso soil; 59.3(49.5), 0.652 and 2.505 for Ikot-Amama 1 soils; 58.0(48.3), 0.704 and 3.682 for Ikot-Nkon soils, respectively. The equilibrium concentration for phosphates (EC-P) were used as desorption index to determine whether the soils could serve as potential sources for their bioavailability to plants and results ranged from 5.0 to 9.90 mgL–1, indicating high vulnerability to phosphate loss. The relationship between phosphate sorption parameters and soil physicochemical properties showed that the Freundlich adsorption intensity factor, nF, strongly correlated negatively with organic carbon and organic matter (r = -0.953 and -0.947; P<0.01), Fe and Mn (r = -0.911 and -0.812, P<0.05). The EC-P correlated strongly with soil pH(H2O) (r = 0.959, P<0.01), clay (r = 0.913, P<0.05), cation exchange capacity (CEC) (r = -0.824, P<0.05), Mn (r = -0.792, P<0.05) and Fe (r = -0.826, P<0.05). The study illustrated that soil management practices which involves the using organic fertilizers as the basis for PO43- sorption in relation to soil properties can be a useful tool for sustainable crop production and environmental soil-water contamination.
Natural clay mineral-periwinkle activated carbon composite: Characterisation and structural insight
Authors: Simon N. , Shaibu S.E. , Fatunla O.K. , Johnson A.S. , Ekpo P.A.
Published: November 2023

The intricacies of a natural clay mineral-periwinkle shell activated carbon (NM-PAC) composite were examined using Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), BET surface area analysis, and Fourier Transform Infrared spectroscopy (FTIR). TEM analysis revealed irregular shaped particles with sizes of around 100 nm and relatively good distribution characteristics. Further examination with SEM supported these findings, showing a heterogeneous microstructure with activated carbon particles evenly distributed within the clay matrix. This uniform distribution was indicative of a high surface area available for adsorption. BET surface area analysis of the NM-PAC was determined to be 72.243 m2/g. FTIR analysis highlighted the presence of characteristic absorption bands related to the vibrational and rotational states of various functional groups. The broad band in the range of 3700–3000 cm-1indicated the stretching vibration of hydroxyl groups, and new bands around 1730 cm-1 , 1250 cm-1, and 1040 cm-1, suggested the presence of carbonyl, carboxyl, and phenol groups respectively. These findings provide valuable insights into the composite's structural properties and its potential for improved adsorption efficiency, particularly for the removal of polar pollutants.

Published: November 2023

This work proposes and analyzes a non-linear deterministic model which describes the outbreak of Coronavirus disease with fomites (environmental reservoirs) propagating the spread of the infection in human population. Suitable Lyapunov functions are constructed to demonstrate the Global Asymptotic Stability (GAS) of both the Endemic Equilibrium (EE) and Disease Free Equilibrium (DFE) of the system. The EE was also found to be epidemiologically relevant when the basic reproduction number of new infections is greater than unity.

Photography in the Face of Cry of Remembrance on Genocide from Beneath the Concrete of Mass Tourism

In the text, I discuss the problems of the genocide experience in the context of mass tourism. I point out that large-scale Holocaust memorials and genocide museums incorporated into the mass-tourism industry are drowning out cries of remembrance. I propose three categories of commemoration: “Captions”, “Monuments” and “Stand-alone Works”. The latter category includes fine art photography among others. Using the case of the photographic series Koenigsgraben, I point out that the category of “Stand-alone Works” seems to have the greatest potential (next to historical enviro mental activeness) to free the cry of remembrance from beneath the concrete of the monuments.
The Priorities and Challenges of Diaspora Education Policies in Poland and Lithuania
Authors: Popyk Anzhela
Published: November 2023

The changing character of diasporas and states’ politics intersect with new challenges in the policymaking process. This study aims to investigate the priorities and hardships of the diaspora education policies in Poland and Lithuania. The study applies the three-dimensional approach (Lesińska, Popyk 2021) to study diaspora policy and draws on qualitative research with the diaspora state institution representatives in the two countries. This paper compares the role of diaspora education policy in a broader policy context, alongside presenting the challenges, namely “socio-demographic”, “methodological”, “political” and “financial”, that state institutions face while ensuring education for the young members of diasporas. It contributes to the scholarship on diaspora policies studies by presenting how state institutions approach and govern the relationships with young diasporas through ensuring education and support social and cultural life of diaspora schools.
Tools of State: Using Research to Inform Policy Decisions in Higher Education
Authors: St. John Edward P.
Published: November 2023

For many decades, states and the federal government have used both qualitative and quantitative studies to inform policy decisions, yet there have been longstanding concerns among qualitative researchers that their work is treated as second class. This paper examines an alternative construction of the problem. Policymakers in states and federal agencies treat policy research as tools of stateâ€”instruments to be used by policy makersâ€”a practice in conflict with the moral stance of many qualitative researchers. Recognizing this problem, I provide guidance for constructing quantitative and qualitative research to inform decisions on policies on equity in preparation for, access to, and academic success in higher education without undermining the researchers’ quest for truth.
Violence in the Arab Revolutions: The Paradigmatic Case of Egypt
Authors: Khosrokhavar Farhad
Published: November 2023

Arab Revolutions promoted non-violence (selmiyah) at their outset, in conjunction with thedignity of the citizen (karama). These mottoes did not resist for a long time against theviolence of the Deep State, the intolerance of the revolutionary actors, and the geopolitics ofthe region, with the notable exception of Tunisia, where geopolitics were not paramount. Thisarticle aims at analyzing the manifold features of violence during the transitional period, fromthe ousting of the President Mubarak in February 2011 up to the third anniversary of theRevolution in January 25, 2014. It purports to show that grass root level actors (the BlackBloc made of Football fans, the secular youth building up the social movement Tamarrod...)and institutional ones (the Judiciary, the security forces representing the Interior Ministry, andthe military at the highest level) rejected the new President from the Muslim Brotherhood.The latter acted in an inept and partisan manner, dialogue becoming impossible and violentrupture becoming unavoidable. The two types of violence (from below and from the DeepState) made democratization impossible. The door was opened for a new period ofauthoritarianism under the aegis of the army.The article does not deal with the geopolitics andtheir role in the radicalization within the Egyptian society.

This article provides an overview of the most relevant aspects of Verständigung in German Criminal Procedure Law. This legal institute regulates agreements between the court, the defendant, and the prosecutor, with the main objective of expediting the procedure by exchanging the defendant’s confession for a mitigation in the punishment. In the first section, the text addresses historical aspects of criminal deals in Germany, such as the public disclosure of its informal existence, the main decisions of higher courts, and the legal regulation of this kind of agreement. Next, it presents a summary of the main arguments in favor and against the institute, mainly those based on procedural principles and maxims recognized by the German law doctrine. Subsequently, the currently applicable regulatory framework is analyzed. Finally, the paper briefly assesses how the study of criminal agreements in German Law can contribute to the criminal policy discussion about deals in other countries, focusing on the Brazilian context.

Published: November 2023

The objective of this paper is to investigate, on the one hand, if it is possible to act in self-defense of animals, and on the other hand, what would be the limits of defensive action. To this end, the paper was divided into two main parts. In the first part, the attempts to ground the crime of maltreatment of animals were analyzed in order to, from them, identify the status that animals occupy in the legal order, concluding that they can be holders of legal goods. Still in the first part, the possibility of self-defense of third parties was investigated, understood as the defense of a right/legal good, in favor of animals, with the caveat that it is a limited defense right compared to the defense of another human being. Finally, in the second part, taking this limitation into account, the boundaries within which self-defense in favor of animals can be admitted were drawn.

Abstract: The article analyzes the demographic situation in Ukraine, which testified to the existence of a deep demographic crisis in Ukraine along with socio-economic problems. The low standard of living, political instability and difficult state conditions caused a dramatic shift in the country's demographic balance. Attention is paid to the problem of migratory activity of the population, in particular forced migration, as a factor influencing the indicators of the demographic situation in the country. Due to the full-scale war caused by russia, millions of women and children were forced to leave the country. It is worth noting, that many years, Ukraine was the main labour donor country for neighboring Poland, Slovakia, the Czech Republic, and Hungary. The consequences for the economy of Ukraine are determined, as well as the main problems relevant for the labour market based on the results of a general analysis of demographic, statistical and analytical information. In any case, depopulation awaits Ukraine - regardless of whether the forced migrants return or not. This means that there will be a shortage of labour in Ukraine, and human capital will be lost. If nothing is changed, in a few years' time, there will be twice as many pensioners in Ukraine as there are working people. That is why the issue of demography should be a priority today and requires urgent measures. The strategy for overcoming the demographic crisis in Ukraine should primarily include two directions: the returning of Ukrainians home from forced emigration; maximum wide-scale work to restore the reproductive potential of the nation.

Inverting Gravity Data to Density and Velocity Models for Selected Area in Southwestern Iraq
Authors: Al-Inizi Athir , Al-Saadi Osamah
Published: November 2023

The gravity method is a measurement of relatively noticeable variations in the Earth’s gravitational field caused by lateral variations in rock's density. In the current research, a new technique is applied on the previous Bouguer map of gravity surveys (conducted from 1940–1950) of the last century, by selecting certain areas in the South-Western desert of Iraqi-territory within the provinces' administrative boundary of Najaf and Anbar. Depending on the theory of gravity inversion where gravity values could be reflected to density-contrast variations with the depths; so, gravity data inversion can be utilized to calculate the models of density and velocity from four selected depth-slices 9.63 Km, 1.1 Km, 0.682 Km and 0.407 Km. The depths were selected using the power spectrum analysis technique of gravity data. Gravity data are inverted based on gravitational anomalies for each depth slice or level and the extracted equivalent depth data from available wells using a connection curve between densities and velocities, which were mostly compatible with Nafe and Drake's standard curve. The inverted gravity data images highlight the behavior of anomalies/structures in the model and domain of density/velocity, which can be utilized in the processing of the recorded seismic data and time to depth conversion, in parallel with available well's data information within the intended study area of South-Western Iraq.

Published: November 2023

Flood damage assessment is considered the essential tool for evaluating risk to civil and agricultural systems in land use planning. The validity of the studies’ outcome depends on the availability of data and their spatial distribution. The present study came to compute flood susceptibility maps utilizing two application models: (i) the frequency ratio, and (ii) the analytical hierarchy process. These models were then tested in the Khazir River basin using GIS with a selection of twelve flood conditioning factors. The flood inventory variables layer and flood-causing factors were created using remote sensing data, a digital elevation model, and secondary data from various sources. Then, the flood inventory map was highlight divided into training and test data, with 105 flood sites (70%) used for training and 45 sites (30%) used for testing. After applying the areas under the curve for the frequency ratio and analytical hierarchy process models, which were 90.6% and 88.9%, respectively, the final flood sensitivity maps showed similar results for the two models, which confirm the effectiveness of the adopted methodology. The study found a considerable spatial variance in flood sensitivity maps, as (21.06%) of the flooded areas are classified as having very low sensitivity to flooding, (24.09%) are classified as having low vulnerability to floods, and (23.79%) are classified as having moderate vulnerability, (24.10%) classified as highly vulnerable to flooding, and (6.96%) classified as highly vulnerable to flooding. Flood danger ranged from very low in mountain locations to very high in plain areas close to the riverbanks. Obtained results could be improved if a land-use planning policy will be applied, in order to establish a master plan for water resources development to avoid flood damage.

Map to Compassion

This article introduces the Human Needs Map — a sense-making tool that helps orient our minds to human needs that drive and trigger us, disrupting relationships and creating conflict. Initially inspired from fieldwork of the Israeli-Palestinian peace process, the Human Needs Map has developed into a systems model that reveals the interior landscape of our Protective body/mind with needs and emotions in dynamic flux.  The model provides a language to speak about the interconnectivity of needs through their synergies and tensions. Naming this emerging and coherent inter-dependency between needs and emotions offers a way to understand emotions as reasonable and provides more vectors to heal, dislodge or re-write narratives and beliefs, which perpetuate conflict. The implication lies not only at the individual level but also at the level of systems change to support the design of social and cultural structures more capable of taking needs and emotions into account. The present article traces the iterative process conceptualizing the model and discovering its internal patterns, followed by a discussion about  the Needs system’s adaptive qualities and its role in creating and perpetuating Conflict, concluding with insights for Israeli-Palestinian peacebuilding.
