Enhancing Web-based Students’ Results and Transcripts Computation in a Hybrid System

An automated computerized examination results management system for tertiary Institution use for end semester examination and generation of transcripts as student’s records processing in a hybrid system is design to overwhelmed the manual or computerized method used for students’ end of semester academic result processing for some institution which was found to be complex and tedium , especially when apply for a large number of students or hybrid system in term of different program. The processing of result in term of grade collection on different courses may involves the entire process time-consuming, error prone and inability to carry out real time control system. The system to be designed is meant to perform student result administration of all facet.  The method to be employ to achieve this approach is top – down hierarchical approach. The expected result show that result and transcript generation was achieved on real time and the monitoring of students with outstanding subject are transfer to a particular partition in the database, where they are monitored on the duration of academic studies before transfer to the first, second and third probations and finally terminated. The system presents a single platform that will be used to manage the processing of all examination records both in part time and full time within the institution. The data used for testing was obtained from the  Department of Academic Planning (DAP) Lagos State Polytechnic, Lagos State. In conclusion, the deployment of academic student processing result and transcripts has demonstrated high sense of efficiency, reliability, error free and real time actualization of student position and good standing.

Antibiotic Prevention of Acute Exacerbations of COPD

An estimated 24 million persons in the United States have COPD on the basis of lung-function testing.1 Globally, COPD is the fourth leading cause of death,2 and in the United States it is the third most common cause of death and chronic complications.3 The average person with COPD has one to two acute exacerbations each year, with wide variation from patient to patient.4 In 2000 in the United States, 726,000 patients were hospitalized with acute exacerbations of COPD.1 During an acute exacerbation, antibiotics are generally administered for 5 to 10 days,5 creating a national burden of 120 million to 480 million antibiotic-days annually. The median hospital stay per exacerbation has been estimated at 9 days.6 In a 2007 Canadian study, the median cost of a hospital stay after an acute exacerbation of COPD was $9,557 (Canadian dollars).7 Acute exacerbations of COPD requiring hospitalization are associated with a 30-day rate of death from any cause of 4 to 30%.6 A study in Sweden showed an all-cause mortality of 26% at 30 days and of 69% at 3 years.8 Acute exacerbations also accelerate the progressive decline in lung function associated with COPD. Overall, the FEV1 falls by approximately 33 ml per year in patients with COPD.4 Each acute exacerbation increases the rate of decline by an additional 2 ml per year4 and by up to 7 ml per year in smokers.

The b-quark mass from non-perturbative Nf=2N_f=2 Heavy Quark Effective Theory at O(1/mh)O(1/m_h)

We report our final estimate of the b-quark mass from $N_f=2$ lattice QCD simulations using Heavy Quark Effective Theory non-perturbatively matched to QCD at $O(1/m_h)$. Treating systematic and statistical errors in a conservative manner, we obtain $\overline{m}_{\rm b}^{\overline{\rm MS}}(2 {\rm GeV})=4.88(15)$ GeV after an extrapolation to the physical point.Comment: 15 pages including figures and tables; as published in Phys.Lett.B / typo in table 4 corrected / footnote 1 expande

ESTIMATING EXCHANGE RATE PASS-THROUGH TO DOMESTIC PRICES; SIERRA LEONE EXPERIENCE

The study conducts an investigation that seeks to evaluate the nature of exchange rate pass-through on consumer prices in Sierra Leone. As a small, open economy, the country is susceptible to exogenous shocks. The exchange rate acts as a medium through which external shocks get transmitted to the real economy. Therefore, the general objective of the study is to assess the effect of the fluctuation of the exchange rate on domestic prices in Sierra Leone. More specifically, it sought to determine which type of exchange rate pass-through exists for Sierra Leone, using annual time series data between 1992 and 2022. The empirical analysis was based on a VECM model. The coefficient of the exchange rate (.5365) which is also significant at the 5% level of significance (p-value = 0.002), indicates that the exchange rate pass-through is incomplete in Sierra Leone. This means that a 1-unit depreciation of the Leone (increase in nominal exchange rate), leads to an increase in Sierra Leone consumer price by .5365 units or approximately 53.65%. This is an indication of indirect pass-through, where importers increase the price of imported goods to maintain their markup in the event of a nominal exchange rate depreciation. The recommendation to the finding is that since it was revealed that Sierra Leone has relatively high exchange rate shocks means that monetary authorities in Sierra Leone should pay more attention to the effects of EXR fluctuation on consumer prices. Measures such as the promotion of local production to substitute imported goods are key to addressing the effects of exchange rate variations. JEL: F31, E31, C32, O24  Article visualizations

Analyses, calibration and validation of evapotranspirationmodels to predict grass-reference evapotranspiration in theSenegal river delta

Study region: Grass-reference evapotranspiration estimation by the Penman-Monteithmethod (PM-ETo) requires a number of climate variables which are not always availableat all weather stations. Different alternative ETo equations have been developed and theirutilization for various local climate conditions requires analyses of their accuracy as com-pared to the standardized Penman-Monteith method. There is a significant lack of data andinformation on this topic in the Senegal River Delta (SRD). Study focus: The objective of this study was to evaluate, calibrate and validate six EToequations ((Trabert, Mahringer, Penman1948, Albrecht, Valiantzas1 and Valiantzas2) forthe SRD. Although all six equations showed good agreement with the PM-ETo (R2\u3e 0.60)for daily ETo estimates, the Valiantzas2 equation was the best model for the Senegal RiverDelta and had the lowest root mean squared difference (RMSE) of 0.45 mm/day and thelowest percent error of estimate (PE) about 7.1%. New hydrological insights for the region: In the case of data limitations, the equationscalibrated in this study are recommended for ETo estimation in the Senegal River Delta. Theresults of this study could be used by agricultural producers, crop consultants, universityresearchers, policy makers for the agricultural, hydrological, and environmental studies aswell as proper allocation and use and forecasting in the SRD where lowland irrigated riceis predominant

Antihydrogen studies in ALPHA

he ALPHA experiment studies antihydrogen as a means to investigate the symmetry of matter and antimatter. Spectroscopic studies of the anti-atom hold the promise of the most precise direct comparisons of matter and antimatter possible. ALPHA was the first to trap antihydrogen in a magnetic trap, allowing the first ever detection of atomic transitions in an anti-atom. More recently, through stochastic heating, we have also been able to put a new limit on the charge neutrality of antihydrogen. ALPHA is currently preparing to perform the first laser-spectroscopy of antihydrogen, hoping to excite the 2s state using a two-photon transition from the 1s state. We discuss the recent results as well as the key developments that led to these successes and discuss how we are preparing to perform the first laser-spectroscopy. We will also discuss plans to use our novel technique for gravitational tests on antihydrogen for a direct measurement of the sign of the gravitational force on antihydrogen

Ionic Tuning of Cobaltites at the Nanoscale

Control of materials through custom design of ionic distributions represents a powerful new approach to develop future technologies ranging from spintronic logic and memory devices to energy storage. Perovskites have shown particular promise for ionic devices due to their high ion mobility and sensitivity to chemical stoichiometry. In this work, we demonstrate a solid-state approach to control of ionic distributions in (La,Sr)CoO$_{3}$ thin films. Depositing a Gd capping layer on the perovskite film, oxygen is controllably extracted from the structure, up-to 0.5 O/u.c. throughout the entire 36 nm thickness. Commensurate with the oxygen extraction, the Co valence state and saturation magnetization show a smooth continuous variation. In contrast, magnetoresistance measurements show no-change in the magnetic anisotropy and a rapid increase in the resistivity over the same range of oxygen stoichiometry. These results suggest significant phase separation, with metallic ferromagnetic regions and oxygen-deficient, insulating, non-ferromagnetic regions, forming percolated networks. Indeed, X-ray diffraction identifies oxygen-vacancy ordering, including transformation to a brownmillerite crystal structure. The unexpected transformation to the brownmillerite phase at ambient temperature is further confirmed by high-resolution scanning transmission electron microscopy which shows significant structural - and correspondingly chemical - phase separation. This work demonstrates room-temperature ionic control of magnetism, electrical resistivity, and crystalline structure in a 36 nm thick film, presenting new opportunities for ionic devices that leverage multiple material functionalities

Surgical intervention on uterine fibromyoma in a country with limited resources: case of the gynaecology-obstetrics department of the Communal Medical Centre of Ratoma Conakry - Guinea

Background: In developing countries, treatment of uterine fibromyoma is confronted with numerous problems, namely: financial inaccessibility to the proposed treatments, fear of surgery and the weakness of the technical platform. The objectives of the study were to calculate the frequency of uterine fibromyomas, describe the socio-demographic characteristics of patients, identify the main clinical data and to describe the modalities of surgical management.Methods: It was a mixed descriptive study, cumulative over a period of 5 years (60 months) with data collection in two phases: a 4-year retrospective study from January 1, 2015 to December 31, 2018 and a 1-year prospective study from January 1, 2019 to December 31, 2019.Results: Authors collected 135 cases of uterine fibromyomas operated on out of a total of 260 cases of gynaecological pathologies, i.e. a frequency of 51.92%. Nulliparous women were the most concerned (45.18%), and women who attended school (60%) and those who did not attend school (40%). Women at home and housewives accounted for 42.20% and 54.07% respectively. Clinically, the circumstances of discovery were dominated by menometrorrhagia and menorrhagia respectively 77.77% and 68.14%. The large uterus was the most frequent physical sign found in 96.29% of cases. Uterine fibromyomas were recorded in 86.6% of cases in women with genital activity. The operative indications were dominated by the large polymyomatous uterus (64.44%), followed by hemorrhagic fibroma (18.52%) The surgical treatment was conservative in 92.60%. The total hysterectomy was performed in 7.40. Lethality was 1.4%.Conclusions: The surgical management of fibroids contrasts conservative treatment (myomectomy) with radical treatment (hysterectomy) with multiple possible approaches (hysteroscopy, vaginal surgery, laparoscopy or laparotomy). In this context, only laparotomy was possible due to lack of equipment. Laparoscopy and hysteroscopy equipment are necessary for less invasive surgery
