Contribution of radiobiphosphonates bone scan in multifocal tuberculous osteomyelitis
Authors: Nabih Salah , Sahel Omar , Benameur Yassir , Doudouh Abderrahim 
Published: June 2020

AbstractWe share the case of a 86-year-old male patient, followed up for recent left hip pain. Interrogation revealed a fever, nocturnal shivering, and bone pains. Standard radiographs and computed tomography centered on both shoulders and pelvis showed osteoarthritis of the left hip and multiple lytic lesions in both humeral heads and clavicles, suggestive of chronic infectious, metabolic, or secondary disease. Bone scan with radiobiphosphonates showed intense and diffuse uptake in the clavicles, the two humeral heads, and at the cervical and dorsal spine. Biopsy of the left humeral head confirmed the diagnosis of tuberculous osteomyelitis, showing an aspect of caseo-follicular tuberculosis. Bone scan with radiobiphosphonates can be used in our context to search other localizations falling within the framework of a polystotic form, and also to guide nonrisk biopsy in such group of patients.
Synchronous osseous metastasis, degenerative changes, and incidental multifocal Paget's disease in a case of newly diagnosed prostatic carcinoma
Authors: Devita Robert , Chagarlamudi Kaushik , Kardan Arash 
Published: June 2020

AbstractTc-99m methylene diphosphonate bone scintigraphy (bone scan) is a highly sensitive technique for the evaluation of osseous pathology. However, the nonspecificity of the method can present diagnostic challenges in differentiating benign from malignant processes. Often, Paget's disease and osseous metastasis can coexist in elderly patients. Therefore, it is important to accurately distinguish the two pathologies, as each has a different prognosis and impacts clinical management. Obtaining the appropriate clinical diagnosis often involves a combination of laboratory, radiographic, and clinical data. We present a case of newly diagnosed prostatic carcinoma presenting with synchronous osseous metastasis, degenerative changes, and incidental multifocal Paget's disease.
Diagnostic value of the rim sign on hepatobiliary scintigraphy
Authors: Shikare Vinod Shekhar 
Published: June 2020

AbstractThe most commonly accepted pathophysiologic mechanism for the appearance of the “hot rim” sign is inflammatory changes from the gallbladder spreading to and affecting the surrounding liver. The “hot rim” sign has clinical relevance, because it is associated with a high incidence of perforated or gangrenous cholecystitis. The presence of these above-mentioned conditions increases the likelihood of complications and warrants urgent surgical evaluation. We present present the findings of on hepatobiliary scintigraphy and adjunct single-photon emission computed tomography/computed tomography-fused imaging in a case of acalculous cholecystitis, which has been confirmed on histopathology (marked degree of acute gangrenous cholecystitis).

Growth of frequently hypercyclic functions for some weighted Taylor shifts on the unit disc
Authors: Mouze Augustin , Munnier Vincent 
Published: June 2020

AbstractFor any
$\alpha \in \mathbb {R},$
we consider the weighted Taylor shift operators
$T_{\alpha }$
acting on the space of analytic functions in the unit disc given by
$T_{\alpha }:H(\mathbb {D})\rightarrow H(\mathbb {D}),$

$$ \begin{align*}f(z)=\sum_{k\geq 0}a_{k}z^{k}\mapsto T_{\alpha}(f)(z)=a_1+\sum_{k\geq 1}\Big(1+\frac{1}{k}\Big)^{\alpha}a_{k+1}z^{k}.\end{align*}$$
We establish the optimal growth of frequently hypercyclic functions for
$T_\alpha $
in terms of
$L^p$
averages,
$1\leq p\leq +\infty $
. This allows us to highlight a critical exponent.
Inhibition of dehydrogenase activity in S. typhimurium by ethanolic and methanolic extracts of Carica papaya and Ocimum gratissimum
Authors: Umeh SI , Umunna IP , Udensi JU 
Published: June 2020

Dehydrogenase and inhibitions of dehydrogenase activities in Salmonella typhimurium by ethanolic and methanolic leaf extracts of Ocimum gratissimum and Carica papaya were investigated. Dehydrogenase activity assay was carried out using 2, 3, 5-triphenyl tetrazolium chloride (TTC) as the electron acceptor. Pure culture of S. typhimurium was exposed to varied concentrations of ethanolic and methanolic extracts of Ocimum gratissimum and Carica papaya [0-4000 μg/ml]. The ethanolic and methanolic extracts exhibited a concentration dependent response against the tested organism. Results obtained revealed that the ethanolic extracts showed a higher bactericidal effect on the test organism than the methanolic extracts at the threshold and total inhibitory concentrations. The IC50 were 45.349 and 15.697; IC100 were 43.732 and 35.526 for ethanolic extracts of Carica papaya and Ocimum gratissimum respectively while the IC50 were 7.108 and 13.696; IC100 were 40.815 and 31.104 for methanolic extracts of Carica papaya and Ocimum gratissimum respectively. This in-vitro study further revealed that the leaf of Carica papaya was more potent on Salmonella typhimurium than the leaf of Ocimum gratissimum. The findings from this study seem to provide the in-vitro evidence that justifies Carica papaya and Ocimum gratissimum as good candidate medicinal plants for the potential treatment of Salmonella typhimurium infections.
Assessment of growth performance of African catfish (Clariasgariepinus) fed with feed produced from blend of pigeon pea (<i>Cajanuscajan</i>) bambara groundnut (<i>Vignasubterranea</i>) and fish meal

Published: June 2020

A 3-factor -factorial experiment (2K) was designed to produce fish feeds from mixture of pigeon pea, bambara groundnut and fish meal as major ingredients, while maize, red palm oil, salt and micro nutrient pre-mix were added as minor ingredients. The raw materials were processed into flours. The ingredients were weighed out in various ratios and mixed. The mixture was extruded; sun-dried and packaged and labeled F1-F8 and a commercial feed labeled F9 served as control. The feeds were feed to juvenile Clariasgariepinus kept in 9 separate plastic bowels and fed for 42 days. The forty-five fish of uniform weight and age were grouped into 9 and stocked in the nine artificial ponds, each pond contained five fish. The feeds were analyzed for proximate composition, while the growth performance of the fish was evaluated at the end of the feeding period. Result showed that F3 (20g pigeon pea, 20g Bambara ground nut and 16g fish meal) contains the highest protein (33.14 %) and F1(20g pigeon pea, 30g bambara ground nut and 16g fish meal) the least (23.13 %). F3 exhibited the highest specific growth rate (1.14 %) followed by the F9 (control) which contains 1.09%. The highest weight gain (16 g) was observed in the fish fed the control feed. However, F3 and F4 (20g pigeon pea, 30g bambara ground nut and 18g fish meal) ranked next to the control with respect to growth performance. It is therefore possible to produce quality catfish feed from bend of pigeon pea, Bambara ground nut and fish meal.

Published: June 2020

The success probability of water wells constructed in crystalline rock terrains is largely dependent on the size, location and interconnectivity of the fractures present in them as well as the amount and nature of the material that may clog the fractures. Geological and geoelectrical studies were proposed and conducted at Tatiko to determine the structures in the underlying basement rocks and evaluate their groundwater potential. Geological study was used to delineate the structural control on groundwater availability while the geoelectrical study (Vertical Electrical Sounding) was used to investigate the properties of the subsurface materials and determine their potential to host sufficient quantity of groundwater.Structural data were plotted on a rosset diagram and showed major structural control trending in the NW – SE direction. Quantitative interpretation of the geoelectric data indicates that the major fractures are within the weathered to competent basement indicating good hydraulic connection between the weathered and fresh basement. The fractures are deepest within the region that showed thicker weathering and are as shallow as 7 meters in other regions. Apparent resistivity of the fractures ranges between 100Ωm and 1200Ωm in most parts of the area with the highest values in the west. An integration of the result clearly showed that the NW and SW parts of the study area are the most favourable for drilling and further groundwater studies and drilling is recommended to a depth of 40m to 50m.

Dans le Parc National d’Azagny, des plantations de cultures pérennes ont été abandonnées, certaines détruites de même que des habitats successivement en 1986 et 2000. Ainsi donc, l’ensemble de la végétation du parc est constitué de reliques de forêts anciennes, de forêts secondaires et de jachères d’âge différents. La présente étude a évalué les changements des traits fonctionnels des espèces végétales arborescentes dans différentes formations du Parc National d’Azagny. Il s’est agi, spécifiquement de : décrire les traits de vie des espèces arborescentes et comparer la composition fonctionnelle entre les forêts anciennes, les forêts secondaires et les jachères de 19 et 33 ans. Le type foliaire, le mode de dissémination et la tolérance à la lumière ont été renseignés pour les individus arborescents de diamètre ≥ 2,5 cm recensés dans des parcelles de 0,25 ha. Le spectre fonctionnel des espèces a été déterminé et des tests de Kruskal-Wallis ont permis de comparer la composition fonctionnelle entre ces formations. L’étude des spectres fonctionnels réalisée sur 1972 individus d’arbres, répartis entre 127 espèces et 46 familles a montré une dominance des espèces à feuilles mésophylles et macrophylles, des espèces sciaphiles et de la zoochorie dans chacun des biotopes. Les tests de Kruskal-Wallis ont montré des différences significatives dans la composition fonctionnelle des habitats au niveau des modalités de traits mégaphylles, pionnières, barochores et zoochores. Ces travaux révèlent un retour des processus écologiques initiaux, donc une bonne reconstitution des milieux perturbés, qui sera facilitée par un renforcement des mesures de protection.Mots clés: Utilisation des terres, succession secondaire, diversité fonctionnelle, Parc National d’Azagny, Côte d’Ivoire.

Au cours des dernières décennies, le Niger a subi des nombreux aléas climatiques qui ont pour conséquences une diminution de la production agricole et une recrudescence des crises alimentaires et nutritionnelles. L’objectif de cette étude, vise à analyser le lien entre l'insécurité alimentaire nutritionnelle et les risques pluviométriques. La méthodologie utilisée est surtout basée sur des enquêtes (entretiens en groupe et entretiens individuels) dont les populations cibles sont celles des régions de Maradi, Tahoua et Tillabéri. Les résultats relèvent qu’il existe une différence significative entre les précipitations des trois régions. Les résultats, ont aussi, montré que les deux risques pluviométriques sont : les sécheresses et les inondations. Mais, au vu de la population rurale, les sécheresses impactent beaucoup négativement sur la sécurité alimentaire et nutritionnelle car elles engendrent une diminution de la production céréalière et une augmentation des prix des céréales locaux. La sécheresse contribue fortement au déterminisme de l’insécurité alimentaire et nutritionnelle au Niger.Mots clés : Risques, sécheresse, inondation, sécurité alimentaire et nutritionnelle.
English Title: Rainfall risks, source of food and nutritional insecurity in Niger
In recent decades, Niger has suffered from numerous climatic hazards which have resulted in a decrease in agricultural production and a resurgence of food and nutrition crises. The objective of this study is to analyze the link between nutritional food insecurity and rainfall risks. The methodology used is mainly based on surveys (group interviews and individual interviews) whose target populations are those of the regions of Maradi, Tahoua and Tillabéri. The results show that there is a significant difference between the precipitation in the three regions. The results also showed that the two rainfall risks are: droughts and floods. However, in view of the rural population, droughts have a very negative impact on food and nutrition security because they cause a reduction in cereal production and an increase in local cereal prices. Drought contributes significantly to the determinism of food and nutritional insecurity in Niger.

Experimental assessment of the performance of reinforced concrete beams strengthened with carbon fiber reinforced polymer laminates
Authors: Yusuf N. , Kaura J.M. , Ocholi A. , Abbas M. 
Published: June 2020

In this study, experimental research is carried out to assess the flexural performance of RC beams strengthened with different amount of CFRP laminates at the tension face. Twelve rectangular RC beams were fabricated and three are un-strengthened and used as reference beams and the remaining nine are strengthened with different amount of CFRP varying from single to triple layers and all are tested to failure under three points bending test. The increase of ultimate strength provided by the bonded CFRP laminates is assessed and failure modes is identified and compared to the un-strengthened RC beams. The results indicated that the flexural capacity of the beams was significantly improved as the amount of the laminates increases that ranged from 20% to 52% increased for single to triple layers laminates. It is concluded that the attachment of CFRP laminates has substantial influence on the performance of CFRP strengthened RC beams. Based on the observed results, recommendations are made that externally application of CFRP laminates can be used for a significant enhancement of the strength deficient RC beams in increasing the ultimate load carrying capacity.

Pressure distribution of a horizontal well in a bounded reservoir with constant pressure top and bottom
Authors: Orene J.J. , Adewole E.S. 
Published: June 2020

The purpose of this study is to develop a mathematical model using Source and Green’s functions for a Horizontal Wells in a Bounded Reservoir with Constant Pressure at the Top and Bottom for the interpretation of pressure responses in the reservoir based on dimensionless pressure and pressure derivative. Reservoir and well parameters investigated revealed what sets of reservoir/ well parameters combination that will prolong infinite activity of the reservoir before steady state sets in. Results show that dimensionless lateral extent does not directly affect the dimensionless pressure and dimensionless pressure derivative for very short well lengths as used in this paper. Dimensionless pressure increases with reservoir pay thickness and delay the time for steady state conditions. In fact external fluid invasion is strongly affected by the size of the pay thickness, thus the minimum time for steady state period to set in is according to the relation TD ≥ LD/5.
Keywords: Bounded, reservoir, steady-state conditions, horizontal well, constant pressure.

Published: June 2020

In this research, an Electromagnetic (E.M) method of groundwater investigations was used as an on-spot assessment tool to test the integrity of the developed borehole in Afe Babalola University, Ado-Ekiti. Some randomly selected functional and abandoned boreholes developed by the Vertical Electrical Sounding (VES) methods were chosen for this study, with the aim to know the potential of the boreholes. Four transverses were established across the institution consisting of two functional and two abandoned boreholes selected from the existing forty boreholes. These weresubjected to E.M method of groundwater investigation using a PQWT S500 series machines. The results obtained from this study produced curve graphs and subsurface profile maps of each transverse location. It was observed that boreholes TR 1 and TR 3, were accurately sited on vertical fractures and weathered formations while TR 2 and TR 4 were wrongly sited at the locations of poor groundwater yielding zone.

Published: June 2020

The study aimed to evaluate the effect of a diet containing extruded linseed (Linum usitatissimum L.) on growth performances, carcass traits and meat quality in Nero Lucano pigs. Sixteen male piglets were weaned at about 50 days of age and divided into two homogeneous groups fed a control diet (C) or a diet containing 3% extruded linseed (EL). The trial lasted 32 weeks and pigs were slaughtered at 9 months of age. Samples from the Longissimus dorsi (Ld) muscle were analysed to assess physical and chemical parameters and intramuscular fatty acid composition. Average daily gain, feed intake and feed conversion ratio were not affected by the diet. Pigs fed the C diet showed a significantly greater slaughter weight in comparison to the EL group (116.50 vs 108.25 kg) Meat pH and chemical composition were not influenced by the diet. No differences were found for shear force (WBS) in raw meat, while cooked meat of the EL group showed a lower WBS value. The EL diet significantly lowered total SFA and increased total PUFA, of both n-6 and n-3 series. Among the n-6, significant differences between dietary treatments were found for linoleic acid. As for the n-3 series, EL feeding significantly enhanced linolenic acid, EPA, DPA and DHA. Feeding EL also significantly lowered the PUFA/SFA and n-6/n-3 ratios and the AI and TI, with benefits for human health. In conclusion, dietary supplementation with 3% EL didn't affect growth performance while it improved the fatty acid profile of meat.

Including protein yield and mastitis resistance in dairy cattle breeding goal optimizes response to selection
Authors: Sagwa C.B. , Okeno T.O. , Kahi A.K. 
Published: June 2020

Selection response from a two-tier nucleus breeding scheme using the current Kenyan breeding goal was compared with an alternative that also accounts for protein yield (PY) and mastitis resistance (MR). The economic value for PY was estimated using a bio-economic model. For mastitis resistance, like other disease resistance traits, the economic value cannot be estimated with profit equations because they have multi-fold effects on input and output, which affects profitability. Therefore, selection index methodology was used. Somatic cell count (SCC) was used as an indicator trait for MR. The ZPAN computer program was used to model the breeding schemes and evaluate response to selection. The alternative breeding goal, which included PY and MR, realized additional KES358.48, 613.55, and 613.65 in annual genetic gain, returns and profit per cow per year, respectively, compared with the current breeding goal. Economic values for PY and MR were KES778.99 and -2364, respectively. Relative economic values for milk yield (MY, kg), fat yield (FY, kg), protein yield (PY, kg), MR, calving interval (CI, days), preweaning daily gain (DG, g/day), postweaning daily gain (PDG, g/day), live weight (LW, kg), preweaning survival (SR1, %), postweaning survival (SR2, %), and length of productive life (PLT, days) were 23 689.80, 4 146.77, 34 665.50, -992.88, 33.66, 62.40, 159.80, 391.94, 987.04, 4 474.37, and 7.56, respectively. This implies that including milk quality traits such as PY in the breeding goal would optimize response to selection in dairy cattle production.
