Mechanizmy sprzyjające koncentracji materiału procesowego na gruncie angielskiej procedury cywilnej
Authors: Kajkowska Ewelina
Published: February 2023

The paper contains an analysis of solutions conducive to completeness of pleadings and evidence, as adopted in the English civil procedure, and compares them to the mechanisms regulated in the Polish Code of Civil Procedure. The first part is an analysis of the general assumptions of the English civil procedure which emerged under the influence of the Woolf ’s and Jackson’s reforms, oriented towards giving effect to the demand for courts’ greater control over the course of proceedings. In the second part the author moves on to describe the detailed solutions adopted under the English Civil Procedure Rules which help make the proceedings more efficient, while making pleadings and evidence more complete, at various stages of court proceedings. In the last part the author compares the English solutions with those enacted under the Polish Code of Civil Procedure. The paper ends with an indication of the potential direction for amendments of the Polish regulation.
Collaboration agreements in Brasil: a legal transaction with the perpetrator of an offence in criminal proceedings
Authors: Brandalise Rodrigo
Published: February 2023

Collaboration agreements had a strong influence on Brazilian procedural law in the face of several operations carried out to investigate crimes like corruption, money laundering, and other crimes committed against the public administration (usually crimes involving powerful criminal organizations). The Brazilian Criminal Procedure Code of 1941 was not conceived with such facts specifically in mind, providing only for the traditional means of obtaining evidence. Nonetheless, Brazil, like other nations, sought to improve its prosecution system. Thus, it created a procedure that, if not unique, is almost unprecedented: it foresees a judicial procedural phase that involves agreements entered into for the collaboration of the accused and that affects the future outcome of the case. The present article aims to analyse these agreements, perceived as judicial transactions, and the effects of their insertion in the evidence law, based on Brazilian legislation.
Propozycja definicji pracy przymusowej – projekt art. 115 § 22b Kodeksu karnego
Authors: Klaus Witold , Makarska Małgorzata
Published: February 2023

Many legislations struggle with defining forced labour. There is not much help from international law, since the only regulation in this matter is the 1930 International Labour Organisation Convention No. 29, which is out of date and not fit for the current needs. The lack of a clear definition of forced labour is one of the main obstacles making this phenomenon (which is becoming increasingly common nowadays) so difficult to identify for law enforcement agencies, which is why its perpetrators are so rarely brought to justice. There are many discussions about whether forced labour should be construed as a separate offence or whether it is (and should be) understood as a form of human trafficking (as many international documents suggest). The authors of this paper prefer the latter view. We believe that such a solution is more productive (especially in the Polish perspective), because Poland has developed a whole system of counteracting human trafficking and providing assistance to its survivors. In addition, law enforcement agencies are well trained in identifying this phenomenon, while a legal definition of forced labour will be an additional (currently lacking) element that can make their efforts in fighting this offence more effective.

Historyczne i prawne aspekty kształtowania się i rozwoju Ukrainy jako całościowego podmiotu międzynarodowego prawa morskiego
Authors: Szevczuk Liliana
Published: February 2023

Historycznie, ukraińska państwowość powstała od początku istnienia Rusi Kijowskiej w średniowiecznym prawie międzynarodowym, którego jednym z instytutów było prawo morskie. Na wszystkich etapach rozwoju swojej państwowości Ukraina była aktywna w działaniach morskich i do pewnego stopnia posiadała status państwa morskiego. Doświadczenia żeglugi i operacji bojowych na rzekach i morzach z czasów Rusi-Ukrainy zostały z powodzeniem zastosowane i opracowane w przyszłości przez państwo kozackie. W XVII-XVIII w. na Morzu Czarnym i Azowskim dominowała morska żegluga kozacka, której celem była z jednej strony obrona ziem ukraińskich, z drugiej – walka prowadzona o wolność handlu morskiego i rzemiosła. Po zniszczeniu państwa kozackiego Rosja przypisała sobie całą dotychczasową historię ukraińskiej państwowości, w tym doświadczenie morskiej działalności narodu ukraińskiego. Rozpad ZSRR i przywrócenie niepodległej Ukrainy wyznaczyły nowy sposób historycznego rozwoju Ukrainy jako pełnoprawnego podmiotu nowoczesnego międzynarodowego prawa morskiego.
Model formalnych i nieformalnych źródeł etyki akademickiej w Polsce
Authors: Barankiewicz Tomasz
Published: February 2023

Artykuł stanowi prezentację kompleksowego modelu formalnych i nieformalnych źródeł etyki akademickiej w Polsce. W tej kwestii autor analizuje trzy modele: 1) model integralności i wiarygodności; 2) model infrastruktury etycznej oraz 3) model społecznej odpowiedzialności nauki. Przy czym zawsze zakładamy, iż dany model stanowi system złożony, tj. składa się z rodzajowo różnych standardów etyki akademickiej, zarówno norm prawnych, jak i norm moralnych. Wskazane trzy modele nie ujawniają się jednak w Polsce w swojej czystej postaci. Raczej w procesie rozwoju stanowią one efekt pewnej ewolucji, ponieważ każdy kolejny model zawiera elementy modelu wcześniejszego. Proces stopniowej erozji modelu klasycznego (integralności i wiarygodności nauki) stanowi rezultat silnych obecnie ocen zewnętrznych, jak np. postulatu społecznej odpowiedzialności nauki oraz postulatu wzrostu efektywności prowadzenia badań naukowych.
Mindfulness and Care Experience in Family Caregivers of Persons Living with Dementia
Authors: Tolea Magdalena I. , Camacho Simone , Cohen Iris R. , Galvin James E.
Published: February 2023

Background:

Greater mindfulness, the practice of awareness and living in the moment without judgement, has been linked to positive caregiving outcomes in dementia caregivers and its impact attributed to greater decentering and emotion regulation abilities. Whether the impact of these mindfulness-based processes varies across caregiver subgroups is unclear.

Objective:

Analyze cross-sectional associations between mindfulness and caregiver psychosocial outcomes, considering different caregiver and patient characteristics.

Methods:

A total of 128 family caregivers of persons living with Alzheimer’s disease and related disorders were assessed on several mindfulness measures (i.e., global; decentering, positive emotion regulation, negative emotion regulation) and provided self-reported appraisals of caregiving experience; care preparedness; confidence, burden, and depression/anxiety. Bivariate relationships between mindfulness and caregiver outcomes were assessed with Pearson’s correlations and stratified by caregiver (women versus men; spouse versus adult child) and patient (mild cognitive impairment (MCI) versus Dementia; AD versus dementia with Lewy bodies; low versus high symptom severity) characteristics.

Results:

Greater mindfulness was associated with positive outcomes and inversely associated with negative outcomes. Stratification identified specific patterns of associations across caregiver groups. Significant correlations were found between all mindfulness measures and caregiving outcomes in male and MCI caregivers while the individual mindfulness component of positive emotion regulation was significantly correlated to outcomes in most caregiver groups.

Conclusion:

Our findings support a link between caregiver mindfulness and improved caregiving outcomes and suggest directions of inquiry into whether the effectiveness of dementia caregiver-support interventions may be improved by targeting specific mindfulness processes or offering a more inclusive all-scope approach depending on individual caregiver or patient characteristics.

Published: February 2023

After age, polymorphisms of the Apolipoprotein E ( APOE) gene are the biggest risk factor for the development of Alzheimer’s disease (AD). During our investigation to discovery biomarkers in plasma, using 2D gel electrophoresis, we found an individual with and unusual apoE isoelectric point compared to APOE ɛ2, ɛ3, and ɛ4 carriers. Whole exome sequencing of APOE from the donor confirmed a single nucleotide polymorphism (SNP) in exon 4, translating to a rare Q222K missense mutation. The apoE ɛ4 (Q222K) mutation did not form dimers or complexes observed for apoE ɛ2 & ɛ3 proteins.
The Role of Local Agents for the Treatment of Localized Upper Tract Urothelial Carcinoma: A Review of the Current Evidence
Authors: Asimakopoulos Anastasios D. , Kochergin Maxim , Klöcker Christian , Gakis Georgios
Published: February 2023

Kidney-sparing surgery (KSS) for upper urinary tract urothelial carcinoma (UTUC) is a promising alternative to radical nephroureterectomy, especially for low-risk cases. However, due to the established risk of ipsilateral UTUC recurrence caused by the implantation of floating neoplastic cells after endoscopic resection, adjuvant endocavitary (endoureteral) instillations have been proposed. Instillation therapy may be also used as primary treatment for UTUC. The two most studied drugs that have been evaluated in both the adjuvant and primary setting of endocavitary instillation are mitomycin C and Bacillus Calmette-Guerin. The current paper provides an overview of the endocavitary treatments for UTUC, focusing on methods of administration, novel formulations, oncologic outcomes (in terms of endocavitary recurrence and progression), as well as on complications. In particular, the role of UGN-101 as a primary chemoablative treatment of primary noninvasive, endoscopically unresectable, low-grade, UTUC has been analysed. The drug achieved a complete response rate of 58% after the induction cycle, with a durable response independently of the maintenance cycle. The cumulative experience on the role of UUT instillation therapy appears encouraging; however, no definitive conclusions can be drawn about its therapeutic benefit. Given the current state of the art, any decision to administer adjuvant endoureteral therapy for UTUC should be carefully weighed against the potential adverse events. Nevertheless, newer investigations that improve visualization during ureteroscopy, genomic characterization, novel drugs and innovative strategies of improved drug delivery are under evaluation. The landscape of KSS for the treatment of the UTUC is evolving and seems promising.

Published: February 2023

In this paper, a novel Phased Array fully Flexible Rayleigh-wave EMAT (PAFR-EMAT) suitable for inspection of curved surface based on flexible coil bias field magnet EMAT is proposed. The PAFR-EMAT consists of a flexible racetrack coil generating long pulsed bias magnetic field instead of the conventional permanent magnets, and flexible meander coils triggered in sequence to induce transient eddy current for exciting enhanced Rayleigh wave of MHz frequency. Based on the Lorentz force mechanism, pulsed electromagnetic fields and the generated ultrasonic waves of the proposed new EMAT are studied through numerical simulation at first. Experiments are conducted then to check the practical performance of the PAFR-EMAT for pipe inspection. Results show that the PAFR-EMAT has good performance in Rayleigh wave generation for inspection of the curved surface of metallic pipe and is capable to detect surface crack of small depth.

BACKGROUND: Varicella vaccination of non-immune post-partum women is recommended to reduce the risk of chickenpox in mothers and their infants. Though rare, transmission of the varicella vaccine strain vOka can occur from recent vaccinees to non-immune contacts who usually develop mild chickenpox. METHODS/RESULTS: Here we describe an infant hospitalized in the neonatal ICU with vaccine-strain varicella due to transmission from their mother who received the varicella vaccine post-partum. We describe the infection prevention and control strategies implemented to prevent further transmission. CONCLUSION: Vaccine-strain varicella transmission from mother to infant is a rare event and its occurrence in the neonatal ICU setting can be challenging. Anticipatory guidance for mothers vaccinated in the postpartum period and support of parents of an infected infant are recommended.

Authors: Göktaş Ayşe , Varlı Murat
Published: February 2023

BACKGROUND: The COVID-19 pandemic has become a major cause of stress at work. OBJECTIVE: To examine the effect of self-management and self-control skills on perceived stress of employees in the COVID-19 period. METHODS: The study’s self-administered survey included demographics and the Perceived Stress Scale (PSS) and Self-Control and Self-Management Scale (SCMS). Associations with PSS were determined using a multiple variable linear regression analysis. RESULTS: Scores for stress (28.45±7.82) and self-management (55.73±12.15) were moderate for employees. Of the 181 employees, 41.43% had a mild, 52.48% had moderate, and 6.07% had severe stress levels. Stress was significantly associated with lower self-management level. A negative relation was found between SCMS and PSS (p = 0.000, r = –0.320). Employees with high self-management skills had low stress levels. Employees also reported negative changes to physical activity, income and sleep. Gender, occupation, income category, compliance with COVID-related rules and self-management were associated with levels of stress (p < 0.05). The regression model explained 24.8% of the variance in stress perception (R2 = 0.248, F = 11.452, p = 0.000). Multiple linear regression analysis showed gender (β = 5.089, 95% CI: 2.820 to 7.358, p = 0.000) compliance with COVID-related rules (β = 2.274, CI: 0.066 to 4.483, p = 0.044), a decrease in income (β = 2.051, CI: –0.64 to 4.166, p = 0.057) and self-management (β = -0.173, CI: –0.258 to –0.087, p = 0.000) were significantly associated with lower scores in the stress perception. CONCLUSION: Self-control and self-management were associated with a decline in mental health. Health-promotion strategies directed at adopting or maintaining positive self-control and self-management-related behaviors should be utilized to address increases in psychological distress during the COVID-19 pandemic.
Navigating between stakeholders in return-to-work processes: A qualitative study exploring experiences of workers on sick leave due to back pain
Authors: Poulsen Anne Grøndahl , Rolving Nanna , Hubeishy Maja Husted , Ørtenblad Lisbeth
Published: February 2023

BACKGROUND: Return-to-work processes involve many stakeholders who need to cooperate to best support the person on sick leave. Yet, there is little knowledge of how workers sick listed due to back pain experience navigating between stakeholders. OBJECTIVE: This study aimed to explore how Danish workers on sick leave due to back pain experience navigating between the involved stakeholders, focusing on settings related to social work, health care and workplace. METHODS: Sixteen individual semi-structured interviews were conducted and data analysed using a thematic analysis approach. RESULTS: Analysis resulted in three themes. 1) ‘Meeting the system’ where establishing a positive relationship with the social worker was hampered by a negative perception of the job centre. This perception was initiated by the convening letter and accentuated by physical meetings being experienced as a waste of time. 2) In ‘Navigating between systems’ some participants lacked support from professionals to navigate the role as messenger between the job centre and health care system. 3) In ‘The workplace–a familiar arena’ workers experience the workplace as a familiar arena, even if negative decisions were made. Analysis additionally revealed that patients’ return-to-work processes could be divided into two types, namely complex and smooth. CONCLUSION: The initial contact from the job centre seems pivotal for the following return-to-work process. The main challenges experienced by sick listed workers were related to the job centre and to being a messenger between job centre and health care, not to their workplace and the decisions made there.

Published: February 2023

La decisión de emigrar es compleja y tiene importantes consecuencias. Quienes emigran suelen ser los más educados y menos satisfechos con su situación en su país de origen, pero se desconocen sus estilos decisionales, si experimentan pesar al decidir y cómo eso se asocia con su bienestar y salud. Esto es analizado en 261 migrantes sudamericanos adultos, de ambos sexos, residentes en Talca (Chile), elegidos por disponibilidad, quienes respondieron instrumentos para medir estilos decisionales, pesar, bienestar y salud. Se observa una fuerte tendencia a la maximización, alto pesar, alto bienestar, y una autoevaluación de salud muy favorable. Se registran asociaciones positivas significativas de maximización con pesar (.374, p = .01), con bienestar (.161, p = .009) y con tres dominios de la calidad de vida relacionada con la salud (.174, p = .005; .169, p = .006; .212, p = .001). Se discuten los resultados y se sugieren nuevos estudios.
Socio-Economic Effect of COVID-19 Pandemic on the Nigerian Worker: An Empirical Analysis
Authors: Abubakar Faruk , Amoto Tijani , Malik Abdul
Published: February 2023

The current study investigated the impact of the COVID-19 pandemic on workers in Nigeria from a socioeconomic standpoint. Nigeria remains one of the most highly affected countries on the African continent; hence the Nigerian government has emulated other countries in taking measures to curtail the spread of the pandemic. These measures include but are not limited to lockdown orders, due to which individuals stop going to work, as well as the closure of factories and businesses. The lockdown order has been applauded for being effective in curtailing the spread of the virus; however, it is deemed to adversely affect the Nigerian workers in both the public and private sectors. Many authors have contributed to literature related to the COVID-19 pandemic, but there is still a paucity of literature investigating the socio-economic effect of the lockdown order on Nigerian workers. To the best of our knowledge, there is no empirical study that investigates the COVID-19 pandemic and its socio-economic impact on civil servants and bankers. The study adopted a survey research design and primary data gathered through the survey was analyzed. The data collection instrument was a questionnaire, which was filled in online using Google Forms. The collected data was analyzed using Pearson Product Moment Correlation (PPMC) and t-test statistical tools. The findings of the study revealed that COVID-19 has an inverse and minimal effect on the socio-economic condition of public and private sector workers. The research proposed, among other things, that the government should place mechanisms to curb excessive price increase of products and services, ensuring that workers in both the public and private sectors are not exploited during the COVID-19 pandemic.

Disaster management is an important part in case of catastrophe for the wellbeing of humanity to save them from severe effects. For active disaster management combined approaches may be used such as applications of artificial intelligence, e.g. geographical analysis, risk mapping and tracking, obscure sensing ability, advance technologies for drone and machine learning and urban planning based on smart cities technology, analysis of hotspots and analysis of environmental impacts are modern technologies which needs to be studied more in the context of disaster management. Researchers of social sciences used different procedures and technology to analyze the hazards, risks and catastrophe between disciplinal.They utilized empirical and evaluative collection of data and itsanalysis techniques. The current study is an overview of present applications of AI being helpful in disaster management throughout its tetrahedral states. AI is important in all states of disaster management as it's a faster solution than other technologies. Integration of two basic supportive tools which are Remote Sensing (RS) and Geographically Information System (GIS) in disaster management provides higher level of planning and its analysis. It can help authorities to take quick and effective decisions in case of natural disaster.
A puha hatalmi gondolkodás és befolyásolás ideológiai előfutárai
Authors: Pál Melinda
Published: February 2023

A puha hatalom húzóerő, vonzáson, együttműködésen, önkéntes azonosulási vágy kiváltásán alapuló befolyásolás. Eszmei gyökere az a nem feudális, az emberi jogokon és az egyéni szabadságon alapuló társadalom, amelyre az amerikai nép az alkotmányában lefektetett klasszikus liberális értékkészlete ékköveként tekint. Ez az eszmei alap a felvilágosodás szellemében fogant széles körű társadalmi értékkonszenzusból fejlődött ki. Jelen tanulmány górcső alá veszi a nyugati civilizációt, értékrendet, ideálokat máig meghatározó, a 17. században induló és a 18. században kiteljesedő felvilágosodást. Vázolja továbbá a szintén a 17. században, az amerikai földrész első kolóniái megalakulásától kezdődő amerikai kivételesség- és küldetéstudat történelmi állomásait. Mivel a soft power elmélet, analitikus koncepció forrásának tekinthető univerzálisnak tartott amerikai értékrendszerre fókuszál, azokat a felvilágosodás kori gondolkodókat és ideálokat vizsgálja, akik, amelyek „tettlegesen” vagy „csak” ideológiai távolságból megalapozták ezt az értékrendszert. Legterjedelmesebben Locke-ot, Hobbest és Kantot. Az amerikai kivételesség- és küldetéstudat fejezetben pedig azoknak a személyiségeknek a munkásságát és hatását emeli ki, akik leegyszerűsítéssel a békepolitikák, a nyugati típusú morális gondolkodás és a liberális internacionalizmus eszméjének előfutárai, majd legfőbb képviselői voltak. A tanulmány zárófejezetei a bipolárisból unilaterális hatalmi helyzetbe került Egyesült Államok külpolitikáinak jellegét vázolja puha hatalmi perspektívából a 2004-es analitikus koncepció kidolgozásáig. Külön kiemeli az újkonzervativizmus térnyerését, azét az ideológiai irányzatét, amely a globális nemzetközi szervezetek által nem támogatott, jóvá nem hagyott iraki beavatkozás elméleti alapját és visszaigazolását jelentette, s amely ily módon ellenirányzatként, negatív mintaként a gyakorlati politikusok számára iránymutatásnak szánt nye-i puha hatalom analitikus koncepciókidolgozásának közvetlen indikátora volt. Ebben a politikai kontextusban a nye-i koncepció a mindenkori békepolitikák elemévé is vált.

Authors: Infante-Jiménez Zoe T. , Ortega-Gómez Priscila , Coutiño Andres Eduardo
Published: February 2023

Objective: Map the innovation networks of blackberry producers in the Los Reyes Michoacán region, as well as to identify the degree of centrality, density and intermediation of the network and some options for improvement.
Design/methodology/approach: Visits and interviews were made to the main collection centers Sunbell, El Cerrito, SPR and Driscoll, to the personnel of Trusts Established in Relation to Agriculture of the Western Region, the Zamora Agency. For the baseline survey, a universe of 50 producers was considered, including partners and main clients; then, all the red was relieved with the "snowball" technique.
Results: 39% of the producers are also dedicated to the production and marketing of avocado. Most of the production (92%) is destined for export. The main collection centers for export are Sunbelle, Splendor and Driscoll. El Molinito and Moradely account for 70% of the total national market.
Agrofertilizadores de Michoacán Agromich, Fertimich, Bucosa and Agrupe concentrate 70% of the inputs sold to producers. The company Procal stands out in the supply and service management network.
Limitations on study/implications: It is a study focused on the Los Reyes region, which could be extended to other regions, crops, and expand the number of actors involved in the study.
Findings/conclusions: The relationships between different actors centralization, inputs-outputs, and intermediation indicators take higher values, which shows the role of producers and key companies (Ere03 and OP01) as source, collector, and articulator actors. It is important to promote high productivity and profitable technologies for innovation

to combat food insecurity and malnutrition among the local populace. However, the giant rat has been reported to harbour many parasites thus, its close association with man in raising them as mini-livestock and the consumption of the meat could be a public health risk to individuals handling them. This study was conducted to investigate the gut parasites and their prevalence on African giant rat in Nsukka metropolis. A total of 21 giant rats comprising 13 males and 8 females were trapped for the study. The giant rats were dissected, and the guts were removed and searched for parasites. A total of 506 parasites where recovered. Four different parasites Trichostrongylus sp., Trichuris muris (nematodes) and Hymenolepis diminuta and Taenia sp. (Platyhelminthes) were identified in the gastrointestinal tract of the giant rats. Hymenolepis diminuta was the most prevalent (100%) while Taenia sp. had the highest mean intensity of 10.15 (7.46 – 12.85, 95% CI) followed by Trichostrongylus sp. Taenia sp. is significantly higher in the caecum of males than the females (p< 0.05). The weight of African giant rat has positive correlation with the prevalence and intensity of the parasites. Given the parasitic load of African giant rats it is recommended that the giant rat should be reared to reduce the intensity of parasitic infection and increase the market value since the farmed ones will be regularly dewormed.
DERIVATION OF THE DYNAMICAL EQUATIONS OF MOTION OF THE R3BP WITH VARIABLE MASSES AND DISK
Authors: Taura Joel John , Leke Oni
Published: February 2023

This paper explores the dynamical equations of the restricted three-body problem with variable masses of the primaries which are enclosed by a disk, when the masses of the primary and the disk vary with time in accordance with the unified Mestschersky law and motion of the primaries is determined by the Gylden-Mestschersky equation. It is seen that the equations of motion differ from those of the restricted three-body problem with variable masses due to the disk mass

Published: February 2023

The experiments were conducted at the Teaching and Research Farm, Faculty of Agriculture, Nasarawa State University, Shabu-Lafia Campus during 2018 and 2019 cropping seasons to evaluate the effect of different rates of biochar on nodulation and yield of soybean in Lafia, Southern Guinea Savanna of Nigeria. The experiments were laid in randomized complete block design (RCBD) with three replications. Biochar at the rates of 0, 4, 8 and 12 tons/ha was incorporated into ridges at planting. Four seeds of soybean were planted per hole at a spacing of 5cm between plants on four manually prepared ridges of 2 m long spaced at approximately 75cm. The seedlings were thinned to two plants after two weeks of planting (WAP). All data collected were subjected to analysis of variance (ANOVA) using GENSTAT statistical package while least significant difference was used to separate treatment means at 5% level of probability. The results obtained showed that biochar at the rate of 8 tons/ha significantly (p<0.05) produced the highest number of nodules (20.8 and 16.4), recorded the heaviest weight per 100 seeds (16.9 and 14.9g) and grain yield of soybean (1304.0 and 1316.7 kg/ha) in both cropping seasons. The results further revealed that the highest dose of biochar (12 tons/ha) in this study did not necessarily influence and increase any parameter tested except over the control (0.0 tons/ha) in both cropping seasons. Therefore biochar at the rate of 8 tons/ha is hereby considered to be the optimum rate for sustainable soybean production in the study area.

Published: February 2023

Overweight and obesity which are known to pose serious health problems are becoming increasingly prevalent in Nigeria which is a sub-Saharan African country. This study utilized the 2018 Nigeria Demographic Health Survey to examine demographic and socio-economic risk factors of overweight and obesity among Nigerian women aged 15-49 years. Exploratory analysis was used to provide basic description of the data while a semiparametric structured additive models was used to describe the relationship between the presumed factors and overweight and obesity status while also accounting for spatial effects at state level. The national prevalence of overweight and obesity among Nigerian women was found to be 27.4%. Increased risk of overweight and obesity among Nigerian women was found to be strongly associated with being older, high educational level, being rich, living in an urban area, having many children, being pregnant, and residing in southern part of Nigeria. In respect to ethnicity and religion, the Fulani tribe and Islamic religion were associated with lower prevalence of overweight and obesity. Overweight and obesity were found to be significantly more prevalent in the Southern parts compared to the Northern parts of Nigeria. The highest and lowest prevalence of overweight and obesity were observed in Anambra and Yobe states respectively. Prevalence of overweight and obesity was higher among Muslim women compared to Christian women since most Northern women are Muslims and most Southern women are Christians. Random (unstructured) spatial effects were significant indicating that overweigh/obesity was influenced by unobserved state specific factors

Information technology has made the world a global village and tele communication plays an indispensible role in this. Queues are predominant features in information processing and transfer. This work examines queue model in relation to telecommunication transfer/ processing problems. Some of the prevalent questions in tele-traffic are “how do we minimize time wastage (how long do I wait?) in the system and what will be the effect on waiting time if the number of operations are altered. In this work, tele-traffic problem was formulated and solution established through a model. Focasting ideas were also suggested. The queue theory has been applied to answer the above questions.

Rapid germination and emergence is an important factor of successful establishment in soybean. Response of soybean varieties to hydro priming duration were investigated under field condition at the Research Farm of the Faculty of Agriculture, Kano University of Science and Technology, Wudil located at Bagauda, and at Gaya fields respectively in 2018 rainy season. The treatment consisted of four improved soybean varieties (TGX-1835, TGX-1904, TGX-1951 and TGX-1955) and four priming duration (0hour (dry seed or control), 4hours, 6hours and 8hours) respectively, they were combined and laid out in a randomized complete block design (RCBD) and replicated three times. The result showed that priming duration has significant effect on stand count and plant height at Gaya alone, there were no significant effects on the number of pods per plant, number of seeds per pod, number seeds per plant, grain yield (t/ha). The highest value was obtained at 8 hour priming duration at both locations. The varieties tested also differed significantly, where TGX-1904 and TGX-1951 recorded superior growth and yield parameters compared to TGX-1835 and TGX-1955 at Gaya. At Bagauda TGX-1904 and TGX-1955 proved superior in terms of stand counts, plant heights at eight weeks after sowing compared to others. From the foregoing, therefore, it is recommended that, priming duration of 8 hours in both locations and varieties TGX-1904 and TGX-1951 could be cultivated by soybean farmers in Gaya while varieties TGX-1904 and TGX-1955 is recommended for farmers in Bagauda for good crop yield.

Toxic metals in wastewater when discharge in to the environment can accumulate in vital organs when ingested, and get concentrated through the food chain causing poisonous effects to living organisms. Alumina modified onion peel composite was used in this study as an adsorbent for the removal of lead, nickel, chromium, copper and zinc ions from Fish pond wastewater via adsorption process.  Batch adsorption experiments were conducted to examine the effect of adsorbent dosage, pH, adsorbate concentration, and contact time on the adsorption of the cations. The optimum adsorbent dosage was 0.3g, pH was 2, contact time was 60 mins and initial concentration was found to be 10 mg/l. The concentration of metal ions present were analyzed using Atomic Absorption Spectrophotometer. The characterization by Fourier Transform Infrared (FTIR) showed absorbance peaks that correspond to hydroxyl, aldehyde, alkyl, amide and carboxylic acid functional groups. These functional groups helped in enhancing the adsorption of the metal ions. Scanning Electron microscope (SEM) analysis was carried out for the morphological characteristics of the adsorbent, before and after adsorption. The experimental isotherm data were analyzed using linear form of Langmuir and Freundlich isotherm models. The Langmuir isotherm provided the best fit for the sorption of Zn2+, Cu2+, Cr3+ and Pb2+ ions with the correlation coefficient (R2) as 0.981, 0.994, 0.9192 and 0.9478 respectively while the Freundlich isotherm had a best fit for the sorption of Ni2+ with the correlation coefficient (R2) of 0.9574. The maximum monolayer adsorption (qm) for copper was found to be the highest

Aluminum Metal Matrix Composites (AMMC) have been becoming suitable materials for many devices in the application of various fields such as medical equipment, aircraft, electrical motors, overhead transmission lines, construction, etc. Aluminum was reinforced with the Fe3O4-(AuTe2) through the recrystallization process, hence, AMMC was successfully developed. The aim was to characterize the microstructure and phase patterns of the developed AMMC and compare it with conventional Aluminum as well as its thermos-mechanical characteristics. Physical, mechanical, and morphological properties of the composite and regular Al were examined. Based on the outcomes, the microstructural examination of the composite showed that the Al matrix had a sizable distribution of reinforcement components. Additionally shown was the creation of new phases, which significantly improved the strength and corrosion resistance of the composite. The influence of the reinforcement materials was found to have greatly enhanced the hardness tests. From 60 HRB for ordinary Al to 92.3 for AMMC, the hardness rose. Hence, after corrosion tests in an acidic solution (5% H2SO4 + H2O) hardness also increased from 41.1 HRB of the conventional Al to 52.8 HRB of the AMMC. Therefore, Corrosion resistance is improved by adding this reinforcement (Al- Fe3O4-(AuTe2) to the composite (lower corrosion rate). We then chose Al-5Fe3O4-10(AuTe2) as an optimal composite after comparing all the samples.

Research works in construction tend to focus on identifying and analyzing risk factors associated with construction projects. The researcher has identified several risk factors associated with building construction projects that are mainly attributed to the contractor. Risk response strategies also developed to include: Avoid, Retain, Reduce and Transfer. However, no research suggests which category of risk to avoid, retain, reduce or transfer. This research aims to map out the risk response strategies for varying risk factors in Building Construction Projects. It can be achievable by identifying the risk factors and response strategies from theliterature, assessing each stakeholder’s level of importance attached to each risk factor, identifying the most relevant risk factors, and mapping out the risk response strategies to varying risk factors. The study adopted a questionnaire where 68 valid questionnaires were analyzed using frequencies, means and percentages. The result shows that there are 54 risk factors associated with building construction projects, out of which 36 are of high significance. There is a significantly positive relationship between the probability of occurrence and the level of impact of the risk factor i.e. higher probability of occurrence is associated with a higher level of impact. The mapping of risk response strategies on risk factors shows that 37% of the risk factors are to be managed by reducing, 28% by avoiding,20% by retaining and 19% by transferring. Thus, the best risk response strategies are ‘reduce’ and ‘avoid’. Finally, the study recommends that all stakeholders understand and implement these risk response strategies accordingly.

Tanaman jahe (Zingiber officinale) merupakan salah satu komoditas tanaman yang termasuk dalam suku Zingiberaceae yang dikenal dengan ginger. Tanaman jahe merupakan rempah yang paling populer dan dimanfaatkan bangsa Eropa pada jaman dahulu.  Selain sebagai tanaman herbal, tanaman jahe menyimpan zat antioksidan yang berguna bagi kesehatan tubuh manusia. Pada tahun 2016, produksi tanaman jahe cenderung mengalami penurunan sedangkan permintaan terus meningkat. Oleh karena itu, perkembangbiakan tanaman jahe dapat dilakukan dengan menggunakan zat pengatur tumbuh auksin yang dapat memacu pertumbuhan dan perkembangan tanaman jahe.  Tujuan penelitian ini adalah untuk mengetahui formulasi yang optimal terhadap pertumbuhan tanaman jahe pada fase vegetatif. Penelitian dilakukan pada bulan februari hingga bulan April di Lahan Pertanian, Fakultas Pertanian, Universitas Pembangunan Nasional “Veteran” Jawa Timur. Penelitian ini menggunakan percobaan yang disusun menggunakan Rancangan Acak Lengkap (RAL) dan diulang sebanyak 3 kali.  Faktor I Konsentrasi ZPT Atonik sebesar 0 ml/l (kontrol), Konsentrasi ZPT Atonik sebesar 2 ml/l, Konsentrasi ZPT Atonik sebesar 4 ml/l, Konsentrasi ZPT Atonik sebesar 6 ml/l, Konsentrasi ZPT Atonik sebesar 8 ml/l, dan Konsentrasi ZPT Atonik sebesar 10 ml/l.  Faktor II Varietas Jahe Emprit, dan Varietas Jahe Merah.  Hasil penelitian menunjukkan perbedaan dosis konsentrasi Zat Pengatur Tumbuh (ZPT) Atonik terhadap berat kering pada fase vegetatif memiliki nilai BNT 5% sejumlah 7,95. Hal ini disebabkan karena pemberian auksin yang tepat dapat meningkatkan penyerapan unsur hara melalui akar.  Pada hasil penelitian juga didapatkan perbedaan yang nyata pada perbedaan varietas tanaman jahe yang berbeda nyata terhadap panjang akar dengan nilai BNT 5% sejumlah 12,46. Hal ini disebabkan karena hormon tersebut dapat memacu serta memacu uatu aktivitas biokimia. Pada diameter batang memiliki perbedaan yang nyata pada perbedaan varietas tanaman jahe yang berbeda nyata dengan nilai BNT 5% sejumlah 0,36. Hal ini disebabkan karena bahan yang digunakan untuk menyuplai pembentukan rimpang tersedia dalam jumlah banyak, maka rimpang yang terbentuk lebih besar dan memengaruhi diameter rimpang.
