description: We have performed several high pressure electrical resistance experiments on Bi1.98Sr2.06Y0.68Cu2O8, an insulating parent compound of the high-Tc Bi2212 family of copper oxide superconductors. We find a resistive anomaly, a downturn at low temperature, that onsets with applied pressure in the 20-40 kbar range. Through both resistance and magnetoresistance measurements, we identify this anomaly as a signature of induced superconductivity. Resistance to higher pressures decreases Tc, giving a maximum of 10 K. The higher pressure measurements exhibit a strong sensitivity to the hydrostaticity of the pressure environment. We make comparisons to the pressure induced superconductivity now ubiquitous in the iron arsenides.

description: The Belinkskii, Khalatnikov and Lifshitz conjecture says that as one approaches space-like singularities in general relativity, 'time derivatives dominate over spatial derivatives' so that the dynamics at any spatial point is well captured by an ordinary differential equation. By now considerable evidence has accumulated in favor of these ideas. Starting with a Hamiltonian framework, we provide a formulation of this conjecture in terms of variables that are tailored to non-perturbative quantization. Our formulation serves as a first step in the analysis of the fate of generic space-like singularities in loop quantum gravity.

description: Using first-principles approaches, this study investigated the efficiency of energy conversion in nanojunctions, described by the thermoelectric figure of merit $ZT$. We obtained the qualitative and quantitative descriptions for the dependence of $ZT$ on temperatures and lengths. A characteristic temperature: $T_{0}= \sqrt{β/γ(l)}$ was observed. When $T\ll T_{0}$, $ZT\propto T^{2}$. When $T\gg T_{0}$, $ZT$ tends to a saturation value. The dependence of $ZT$ on the wire length for the metallic atomic chains is opposite to that for the insulating molecules: for aluminum atomic (conducting) wires, the saturation value of $ZT$ increases as the length increases; while for alkanethiol (insulating) chains, the saturation value of $ZT$ decreases as the length increases. $ZT$ can also be enhanced by choosing low-elasticity bridging materials or creating poor thermal contacts in nanojunctions. The results of this study may be of interest to research attempting to increase the efficiency of energy conversion in nano thermoelectric devices.

name: Abonyi, Michael Chinweuba
Publisher: name: Nigerian Medical Journal
Year: 2024

description: Background: The ageing population worldwide presents a significant challenge for healthcare systems, with malnutrition being a common problem among elderly individuals, particularly those hospitalized. Assessing nutritional status is crucial for identifying and addressing malnutrition in this population. This study aimed to assess the prevalence of malnutrition among elderly hospitalized patients in a Nigerian tertiary healthcare setting.

Methodology: This was a hospital-based descriptive and cross-sectional study conducted from March to June 2023, involving 122 patients aged 60 years and above. Demographic data and anthropometric measurements were collected, and the Short-form Mini Nutritional Assessment (MNA-SF) tool was used to assess nutritional status. The reliability of the MNA-SF was assessed using Cronbach’s α coefficient and item-to-total score correlations.

Results: The mean MNA score was 14.4 ± 5.3, with 71.3% of participants classified as malnourished, 22.1% at risk of malnutrition, and 6.6% well-nourished. Significant differences were observed in the body mass index (BMI) of nourished, at-risk, and malnourished individuals respectively (23.3 ± 3.6 kg/m2, 22.5 ± 3.8 kg/m2, and 19.6 ± 2.8 kg/m2, p < 0.001). The MNA-SF tool demonstrated acceptable reliability (Cronbach’s α coefficient = 0.777), with significant correlations between total MNA scores and most MNA-SF questions.

Conclusion: The high prevalence of malnutrition among elderly hospitalized patients in this Nigerian tertiary hospital emphasizes the importance of implementing routine nutritional screening protocols and targeted nutritional interventions for improved health outcomes among the elderly.

description: We demonstrate the possibility to build a thermoelectric engine using a one dimensional gas of molecules with unequal masses and hard-point interaction. Most importantly, we show that the efficiency of this engine is determined by a new parameter YT which is different from the well known figure of merit ZT. Even though the efficiency of this particular model is low, our results shed new light on the problem and open the possibility to build efficient thermoelectric engines.

description: Weakly ferromagnetic alloys are being used by several groups in the study of superconducting/ferromagnetic hybrid systems. Because spin-flip and spin-orbit scattering in such alloys disrupt the penetration of pair correlations into the ferromagnetic material, it is desirable to have a direct measurement of the spin memory length in such alloys. We have measured the spin memory length at 4.2 K in sputtered Pd0.88Ni0.12 and Pd0.987Fe0.013 alloys using methods based on current-perpendicular-to-plane giant magnetoresistance. The alloys are incorporated into hybrid spin valves of various types, and the spin memory length is determined by fits of the Valet-Fert spin-transport equations to data of magnetoresistance vs. alloy thickness. For the case of PdNi alloy, the resulting values of the spin memory length are lsf(PdNi) = 2.8 +/- 0.5 nm and 5.4 +/- 0.6 nm, depending on whether or not the PdNi is exchange biased by an adjacent Permalloy layer. For PdFe, the spin memory length is somewhat longer, lsf(PdFe) = 9.6 +/- 2 nm, consistent with earlier measurements indicating lower spin-orbit scattering in that material. Unfortunately, even the longer spin memory length in PdFe may not be long enough to facilitate observation of spin-triplet superconducting correlations predicted to occur in superconducting/ferromagnetic hybrid systems in the presence of magnetic inhomogeneity.

Suzaku Constraints on the Soft and Hard Excess Emissions from Abell 2199

description: The nearby ($z=0.03015$) cluster of galaxies Abell~2199 was observed by Suzaku in X-rays, with five pointings for $\sim 20$ ks each. From the XIS data, the temperature and metal abundance profiles were derived out to $\sim 700$ kpc (0.4 times virial radius). Both these quantities decrease gradually from the center to peripheries by a factor of $\sim 2$, while the oxygen abundance tends to be flat. The temperature within 12' ($\sim 430$ kpc) is $\sim 4$ keV, and the 0.5--10 keV X-ray luminosity integrated up to 30' is $(2.9 \pm 0.1) \times 10^{44}$ erg s$^{-1}$, in agreement with previous XMM-Newton measurements. Above this thermal emission, no significant excess was found either in the XIS range below $\sim 1$ keV, or in the HXD-PIN range above $\sim 15$ keV. The 90%-confidence upper limit on the emission measure of an assumed 0.2 keV warm gas is (3.7--7.5) $\times 10^{62}$ cm$^{-3}$ arcmin$^{-2}$, which is 3.7--7.6 times tighter than the detection reported with XMM-Newton. The 90%-confidence upper limit on the 20--80 keV luminosity of any power law component is $1.8 \times 10^{43}$ erg s$^{-1}$, assuming a photon index of 2.0. Although this upper limit does not reject the possible 2.1$σ$ detection by the BeppoSAX PDS, it is a factor of 2.1 tighter than that of the PDS if both are considered upper limits. The non-detection of the hard excess can be reconciled with the upper limit on diffuse radio emission, without invoking the very low magnetic fields ($< 0.073 μ$G) which were suggested previously.

description: A microscopic theory for the spin triplet Cooper pairing in non-centrosymmetric superconductors like CePt_3Si and CeTSi_3 (T=Rh, Ir) is presented. The lack of inversion symmetry leads to new anomalous spin fluctuations which stabilize the triplet part in addition to the singlet part originating from the centrosymmetric spin fluctuations. It is shown that both parts have similar nontrivial momentum dependence of A_1 type. Therefore the mixed singlet-triplet gap function has accidental line nodes on both Fermi surface sheets which are stable as function of temperature. This gap function explains the salient features of CePt_3Si and CeTSi_3 superconductors.

description: Background: Cardiovascular diseases (CVD) are widespread and significantly contribute to global mortality with a rising prevalence in developing countries. The aim of this study was to identify the pattern and outcome of admissions related to cardiovascular diseases within the medical wards at the Rivers State University Teaching Hospital.

Methodology: The study was a retrospective cross-sectional hospital-based study. The records of all patients admitted into the medical wards from January 2021 to December 2022 were extracted to include information on biodata, admitting diagnosis, duration of admission, and patients’ outcomes.

Results: Over this 2-year period, a total of 1,540 patients were admitted into the wards and 751 (48.8%) persons were admitted for CVDs with a mean age of 59.6±15. 1years.The commonest cardiovascular diseases documented included heart failure (HF) and cerebrovascular accident (CVA) which occurred in 251(33.4%) and 311(41.1%) patients respectively. Other CVDs recorded were hypertensive crisis in 163(21.7%), acute coronary syndrome (ACS) in 12(1.6%) and pulmonary embolism (PE) in 6(0.8%) patients. During the study period, 311 deaths were recorded representing 20.2% of all admissions with 146(46.6%) hospital deaths attributed to CVDs, accounting for 19.4% of the total cardiovascular admissions with 125 of these deaths occurring in patients with CVA and HF.

Conclusion: Heart failure and Cerebrovascular accidents emerged as significant contributors to the morbidity and mortality of patients on admission in Rivers State. Policies to incorporate appropriate, preventive and management strategies in the community to reflect this distribution are essential to significantly reduce cardiovascular deaths in our population.

description: Papua New Guinea (PNG) had its democratic institutions and processes established during the 1960’s. This process began with the establishment of the Legislative Council in 1959 and later the House of Assembly in 1964. The discussion of the Organic Law on the Integrity of Political Parties and Candidates (OLIPPAC) relates to political parties and candidates, therefore a brief mention will be made on the historical evolution of political parties in Papua New Guinea. Political parties first emerged in Papua New Guinea in 1967. Two of the earliest parties were the Pangu Party and the United Party. Political parties in the history of PNG first contested the 1968 national election (Moore and Kooyman, 1998). The emergence of the different groups that later became political parties became sporadic which brought about the multiparty nature of the party system in the country. During the 1972 election, new political groups such as the People’s Progress Party, National Party, Melanesian Alliance and other smaller groups emerged and contested the election. Other groups based on nationalistic sentiments also contested but most of them did not last after the 1982 national election (May, 1982). This paper will look at the failures of the OLIPPAC. The first part will be a general discussion of the OLIPPAC. The second part will look at the events after the 2002 elections, which have affected the effectiveness of the OLIPPAC. The third part will discuss how and why the OLIPPAC has failed to provide the much-needed political stability. And finally the paper will look at some remedies to the failures.

description: A search for supersymmetric partners of quarks is performed in the topology of multijet events accompanied by at least one tau lepton decaying hadronically and large missing transverse energy. Approximately 1 fb-1 of ppbar collision data from the Fermilab Tevatron Collider at a center of mass energy of 1.96 TeV recorded by the D0 detector is analyzed. Results are combined with the previously published D0 inclusive search for squarks and gluinos. No evidence of physics beyond the standard model is found and lower limits on the squark mass up to 410 GeV are derived in the framework of minimal supergravity with tan(beta)=15, A_0=-2m_0 and mu<0, in the region where decays to tau leptons dominate. Gaugino masses m_1/2 are excluded up to 172 GeV.

description: The fractional Fokker-Planck equation for subdiffusion in time-dependent force fields is derived from the underlying continuous time random walk. Its limitations are discussed and it is then applied to the study of subdiffusion under the influence of a time-periodic rectangular force. As a main result, we show that such a force does not affect the universal scaling relation between the anomalous current and diffusion when applied to the biased dynamics: in the long time limit subdiffusion current and anomalous diffusion are immune to the driving. This is in sharp contrast with the unbiased case when the subdiffusion coefficient can be strongly enhanced, i.e. a zero-frequency response to a periodic driving is present.

description: In this paper, we analyze the performance of an electro-optic modulator based on a single quantum dot strongly coupled to a nano-resonator, where electrical control of the quantum dot frequency is achieved via quantum confined Stark effect. Using realistic system parameters, we show that modulation speeds of a few tens of GHz are achievable with this system, while the energy per switching operation can be as small as 0.5 fJ. In addition, we study the non-linear distortion, and the effect of pure quantum dot dephasing on the performance of the modulator.

Governance and Governmentality: The Influence of the Bologna Process on Ethiopian Higher Education
Creators: name: Mekonnen, Geberew
Publisher: name: University Of Tasmania
Year: 2023
Subjects: Education policy

Educational administration, management and leadership

description: The purpose of this study was to investigate the Ethiopian public universities' governance systems in the context of the Bologna Process. It specifically aimed at understanding and interpreting the perceptions and strategic responses of leaders, instructors, and students of public universities towards their governance systems. In the past few years, there has been a prevailing chorus of complaints among academic leaders, instructors, and students about university governance. The Ethiopian government acknowledged the stakeholders' dissatisfaction with governance and placed it as one of the priorities in the Growth Transformational Plan-II of 2016-2020. This dissatisfaction and the introduction of newly adopted elements of the Bologna Process brought enormous pressures to the governance of public universities. In addition, little is known about the Ethiopian higher education institutions' governance in the context of the Bologna Process. This limited information on higher education governance in the Ethiopian context and the dissatisfaction of university key actors about the university governance systems provided the impetus for this study.

description: Robotics and automation have significantly transformed CNC machining operations, enhancing productivity, precision, and efficiency. Robots are employed to load and unload raw materials, workpieces, and finished parts onto CNC machines. They can efficiently handle heavy and bulky components, reducing the demand of manual labor and minimizing the risk of injuries. Robots can also be used in CNC machine tools to perform tasks such as automatic tool changing system, part inspection, and workpiece positioning. Automation technologies, including in-line inspection systems and non-destructive testing methods, can be integrated into CNC machining cells to enhance accuracy and reduce scrap and rework in machining operations. These systems collect real-time data on process parameters and machine tool performance to predict maintenance, optimize machining parameters, and improve overall efficiency. In the study, applications of robotics and automation in modification of CNC machine tools are reviewed and discussed. Different applications of robotics and automations in CNC machine tools such as automated material handling, automatic tool changing, robotic work cells, adaptive machining, machine tending, quality inspection, data monitoring and analysis and production line integration are discussed. Thus, by analyzing recent achievements in published papers, new ideas and concepts of future research works are suggested. As a result, accuracy as well as productivity in process of part production can be enhanced by applying the robotics and automation in CNC machining operations.

description: It is possible that a system composed of up, down and strange quarks consists the true ground state of nuclear matter at high densities and low temperatures. This exotic plasma, called strange quark matter (SQM), seems to be even more favorable energetically if quarks are in a superconducting state, the so-called color-flavor locked state. Here are presented calculations made on the basis of the MIT bag model considering the influence of finite temperature on the allowed parameters characterizing the system for stability of bulk SQM (the so-called stability windows) and also for strangelets, small lumps of SQM, both in the color-flavor locking scenario. We compare these results with the unpaired SQM and also briefly discuss some astrophysical implications of them. Also, the issue of strangelet's electric charge is discussed. The effects of dynamical screening, though important for non-paired SQM strangelets, are not relevant when considering pairing among all three flavor and colors of quarks.

Initiation and quest in some early Canadian journals
Creators: name: Hodgson, John Maurice Devereux
Publisher: name: University of British Columbia
Year: 2011

description: This thesis examines a number of Canadian Captivity and Exploration journals dating from Radisson's account of his captivity in 1652 to the investigation of the West Coast by the naturalist David Douglas in 1826. The examination attempts to reveal these early journal writers not only as men undertaking a specific physical task, but as authors reflecting the spirit of their enterprise in their journals. The genre of the travel journal reflects the literary spirit of the age in which they were written; sometimes allied to it, and at times quite antithetical to it. Each journal exposes an individual, uniquely aware of his position in time and place, attempting to express a novel experience in terms familiar to himself and his readers. The result is not always satisfying from a literary point of view, but then the criterion of the thesis has not been stylistically based,but has been primarily interested in revealing the individual in his particular endeavour. The results are not consistent nor conclusive, but the examination of the journal, which is the lasting testimony of physical trial, uncovers a fresh literary genre which is usually investigated only by the historian or the geographer. The thesis is divided into two primary sections: chapter two, which deals with the Captivity journals of John Tanner, Alexander Henry, John Jewitt and Pierre Radisson; and chapter three which investigates the Exploration journals of Radisson, Henry Kelsey, William Cormack, David Douglas, Alexander Mackenzie, David Thompson and Samuel Hearne. The introductory chapter gives some background to the genre of the travel journal from the period of Richard Hakluyt to the esoteric world of Science Fiction. The nature of heroic endeavour and the position of the travel journal as source material for authors is also briefly discussed. In handling a subject which refuses to be limited to any one discipline, nothing conclusive can be stated. However, it seems important to isolate the travel journal in its attempt to describe the human condition. The environment and terms are not usually associated with literature, and yet the genre manages, unexpectedly, to point up those universal themes so essential to all creative writing.
title: Tense-Aspect Categories and Standard Negation in Five Bamileke Languages of Cameroon: A Descriptive and Comparative Study

description: This thesis is a study of tense-aspect and standard negation in five Bamileke languages: Ngiemboon, Feʔfeʔ, Ghomalaʔ, Ngombale, and Medumba. It aims at a detailed description of the mechanisms for expressing tense-aspect categories and standard negation in each of the five languages under investigation and a comparison of the tense-aspect systems and standard negation across the languages analysed. The ultimate aim of the comparison is to test previous scholars’ claims that aspects of grammar largely exhibit the same properties from one Bamileke language to the other (Nissim 1975, Sonkoue 2014). The study is mainly synchronic and is based on working sessions with language consultants, using a questionnaire and a list of topics for collecting short oral texts. The conceptual framework that guided the analysis and interpretation of the data relies basically on the works by Comrie (1976, 1985) and Dahl (1985) on tense-aspect and Miestamo (2000, 2003, 2005) on negation. The main findings of the study are: (i) tense and aspect are encoded differently in each of the languages analysed. Verb forms may either lack an overt tense or aspect marking, they may exhibit a single marker, or a construction including at least two elements (for example, two tense markers following each other). Tense-aspect markers may also have one or more basic uses. (ii) Tense-aspect and standard negation interact in an interesting way in the languages analysed; and (iii) on close inspection, both the similarities and differences between the five languages analysed with respect to tense-aspect and standard negation prove to be considerable. Thus, this study departs from previous scholars’ claims and argues that Bamileke languages show a high degree of similarity in the basics of their tense-aspect systems and standard negation. Nevertheless, when deep analyses are carried out in each individual language within these domains of grammar, comparing the languages indicates that they have both, similarities and differences and thus, neither should be de-emphasised. In addition, the study indicates that various hypotheses about diachronic change relating to tense-aspect systems and standard negation in the languages under investigation, and to a certain extent in related languages outside the Bamileke group, can be advanced. For example, it is posited in the study that the near past markers (kà in Ngiemboon, kə̄ in Feʔfeʔ and Ghomalaʔ, and kə̀ in Ngombale) are probably derived from the same source. The study closes with recommendations for future research. It recommends, for instance, an analysis of the extended functions of tense-aspect categories in each of the languages analysed.

description: Background: The utilization of HIV testing services in Nigeria has not been optimal due to socioeconomic and demographic factors such as educational level, place of residence, and religion. For Nigeria to achieve epidemic control, pregnant women need to know their HIV status through HIV testing, which is the gateway to HIV prevention, care, support, and treatment services. Therefore, the purpose of this study was to determine the predictors of HIV testing among Nigerian pregnant women aged 15-49 years HIV testing during antenatal visits or childbirth.

Methodology: Secondary data analyses of 659 pregnant women randomly selected from the multiple imputation datasets of the 2013 Nigeria Demographic and Health Survey (NDHS)were done using SPSS version 25. Data on socio-demographic characteristics, HIV stigmatizing attitudes, and HIV testing were retrieved from the dataset for the study. Bivariate and multivariate regression analyses were done to determine the predictors of HIV testing.

Results: The prevalence of self-reported HIV testing and receiving results among women of reproductive age was 36.72%. Bivariate model findings showed that educational level, place of residence, and religion were statistically significant predictors of HIV testing among pregnant women. Only educational level and place of residence significantly predicted pregnant women's HIV testing in the parsimonious multivariable regression model. Pregnant women with higher levels of education (Primary Education, AOR, 1.85; 95% CI, 1.07,3.19; Secondary Education, AOR, 3.75; 95% CI:1.93, 7.28; Higher Education, AOR, 11.23; 95% CI: 4.40, 28.68) and those living in urban areas (AOR, 1.60: 95% CI:1.03, 2.47) were more likely to test for HIV than those with no education and those living in the rural areas.

Conclusion: This study identified having a higher level of education and living in urban areas as predictors of HIV testing, therefore, more efforts are needed to have women with lower levels of education and those living in rural areas test for HIV as a strategy for the elimination of mother-to-child transmission of HIV.

description: Background: Even though the vaginal route is said to be the gynaecologist route of surgery, abdominal hysterectomy remains the predominant method of uterine removal in most parts of the world, despite the evidence of the safety of vaginal hysterectomy. The study aims to determine the prevalence, socio-demographic variables, indications as well as outcome of vaginal hysterectomy at Federal Teaching Hospital (FTH) Katsina, during the 5-year study period.

Methodology: A five-year retrospective study on vaginal hysterectomy was conducted in Federal Teaching Hospital, Katsina from 1st January 2015 to 31st December 2019.

Results: The rate of hysterectomies (Abdominal & Vaginal) was 21.6% of the total major gynaecological surgeries performed during the study period. Vaginal hysterectomy accounted for 6.7%. The mean age and parity of the patients were 56.06+/- 9.55 years and 10.17+/- 4.57 respectively. The commonest indication was Utero-vaginal Prolapse (88.9%) and 80.5% (29) of the patients had no complications. Most of the patients (94.4%) were discharged within 7 days of surgery and there was no fatality.

Conclusion: The rate of vaginal hysterectomy in our centre is low. Most of the patients were grand multiparous with the main indication being Uterovaginal prolapse. It is associated with favourable outcomes and very low complication rates.
