Blast damaged zone influence on water and solute exchange between backfilled open-pit and the environment

In-pit disposal of mine wastes is a promising alternative management approach to conventional disposal facilities. However, wastes disposed of in pits are in direct contact with the surrounding rock, and regional groundwater could flow in the wastes and contribute to contaminant dispersion in the environment. Blasting operations result in the creation of new fractures close to pit walls, which can provide preferential flow paths and divert flow around backfilled masses, thus reducing contamination risks. The present study aimed to investigate the influence of the blast damage zone (BDZ) on water and solute exchanges using 3D numerical modelling. Results highlighted the BDZ potential beneficial effect which could reduce the flow rate though backfilled tailings by 40% and decrease contaminants release rate in the environment by around 30%. This paper presents the BDZ simulation approaches and discusses the main results obtained. RÉSUMÉ La déposition de rejets miniers dans les fosses est une alternative prometteuse aux approches de gestion conventionnelles. Cependant, les rejets déposés dans les fosses sont en contact direct avec le roc, permettant ainsi à l’eau souterraine de s’écouler dans les rejets, et contribuant à la dispersion des contaminants dans l’environnement. Les opérations de sautage entrainent la création de nouvelles fractures autour de la fosse, formant ainsi des chemins préférentiels pouvant contribuer à dévier l’eau autour des rejets remblayés et réduisant ainsi les risques de contamination. La présente étude avait pour objectif d’investiguer l’influence de la zone endommagée par sautage (ZES) sur les flux d’eau et de contaminant au moyen de modèles numériques 3D. Les résultats ont montré le potentiel effet bénéfique de la ZES laquelle pourrait permettre de réduire jusqu’à 40 % le débit dans les rejets remblayés et d’environ 30 % le flux de soluté. Cet article présente le modèle de la ZES et discute des principaux résultats obtenus.
Thevetia peruviana (Pers.) K. Schum. Potential Antifungal Agent Against Mycosphaerella fijiensis Morelet, Fungi Responsible of Black Leaf Streak Disease (BLSD) of Plantain (Musa spp)

Alternatives to synthetic chemicals are undertaken against phytopathogens. The aim of this work is to evaluate the effect of seed extracts of Thevetia peruviana (Pers.) K. Schum. on Mycosphaerella fijiensis Morelet, fungus responsible for banana black leaf streak disease. Five extracts of T. peruviana, hexane extract (HE), ethyl acetate extract (EAE), acetone extract (AcE), methanol extract (ME) and aqueous extract (AqE), and a fungicide, Azoxystrobin were used. GC-MS of acetone extract was performed. Fifty (50) strains of M. fijiensis per sampling site were tested. Three concentrations of extracts 6.25 (C1), 12.5 (C2), and 25 (C3) μl/ml, a negative control (0 μl/ml) and 10 ppm of azoxystrobin were used for the tests. The MIC50 and MIC90 were determined. GC-MS showed chemical compounds with different molecular height such as acids, sugars, and esters. AcE and AqE significantly reduced M. fijiensis germ tube growth at C2 and C3 concentrations and with inhibition percentage respectively ranged of 60-90% and 40-80%. The growth levels of the germ tubes were above the strobilurin resistance threshold at Njombe and peasant plantation, ranging from 77.9% to 92.3%. AcE showed the same or superior efficacy as the fungicide used on conidial germination at all tested Journal of Agricultural Studies ISSN 2166-0379 2021, Vol. 9, No. 2 http://jas.macrothink. org 366 concentrations. The MIC50 totally reducing mycelial growth and conidial germination was 6.25 μl/ml. T. peruviana seeds extracts can be exploited in integrated pests management against M. fijiensis.
The Experience of Participating in a Choir in the Pulmonary Rehabilitation Program of the ABC Medical School: Patients’ Perception

Result: In this period, 44 patients were interviewed, 23 men and 21 women aged 67 (40 ± 84), MRC 2 (1 ± 4), FEV1 after BD% 45 (15 ± 107) and 05 of the total group maintained the work activity. The subjective perceptions regarding the benefits of this activity were: emotional 45% (20); socialization 36% (16); physical 14% (6); did not know how to answer 5% (2). In the structured interview, five patients considered this choral singing activity before participating in the PRP and after the 41 participation; they considered it possible to develop this activity even with respiratory disease. Conclusion: The singing activity in patients with CRD has been shown to enhance health treatment, associated with the physical benefits already proven by the participation of PRP, the main benefit for them being the emotional state and socialization.
Fit for purpose? An analysis of the effectiveness of Professional Learning Communities for continuous professional teacher development in South Africa

To ensure quality teaching, teachers require continuous professional teacher development (CPTD) opportunities. In South Africa, CPTD faces many challenges however, including most notably budget constraints. Because they have been found to be cost-effective, Professional Learning Communities (PLCs) could constitute a promising way forward in the country. In a PLC, classroom teachers, school managers and/or subject advisors come together to collectively determine their CPTD needs and to set up activities that can help them meeting those needs. Hence, PLCs are needs-based driven and stimulate collaborative learning – characteristics of effective CPTD. In 2017-2018, the South African Department of Basic Education initiated 12 inter-school pilot PLCs among teachers of grade 1 to 6 in the provinces of Free State, North West and the Northern Cape. In this paper, we examine participating teachers’ perceptions of the effectiveness of these PLCs, drawing on focus group discussions and chat box stories, and triangulate their impressions with PLC observations. We find that teachers perceive PLCs to be effective when they are (1) needs-driven, (2) supported by the school management, (3) skillfully facilitated, (4) based on mutual trust and respect, (5) regularly guided by input from external experts and (6) when participating teachers share a sense of collective responsibility for student learning. Promisingly, results also indicate that participation in PLCs increases collaboration among teachers.
Prognostic Impact of Ablative Therapy in Oligometastatic Non-Small-Cell Lung Cancer (NSCLC) with Unresectable Primary Tumor

Purpose: Patients with Oligometastatic (OM) non-small-cell lung cancer (NSCLC) (≤ 3 metastases) might benefit from radical ablative treatment of both primary tumor and metastases. However, the role of ablative therapy in OM patients with locally advance primary tumor has not been evaluated. The aim of our study was to analyze the efficacy and safety of ablative treatment in patients with unresectable primary tumor and synchronous Oligometastases, in terms of response rate, progression free survival (PFS) and overall survival (OS). Methods/Patients: Retrospective study of patients with Oligometastatic NSCLC (≤ 3 lesions in a unique location) and unresectable primary tumor, treated with radical intent (chemo-radiotherapy for primary tumor and surgery, radiotherapy, Stereotactic Body Radiation Therapy (SBRT) or radiofrequency for all known metastases) between October 2011 and March 2015. Results: Thirty patients met inclusion criteria. Median age was 58 years, 76.6% were male, and 96.6% had ECOG 0-1. Histology: Adenocarcinoma (63.6%), squamous carcinoma (20%), and other histology (13.4%). All patients had unresectable primary tumor and/or mediastinal lymph nodes. Site of metastases: brain (46.6%), lung (23.3%), bone (20%), other locations (9.9%). Sequential thoracic radiotherapy (40%) and concomitant radiotherapy (60%). Treatment of metastases: SBRT (53.3%), external radiotherapy (26.6%), surgery (13.6%), radiofrequency (3.3%), none (3.3%). Toxicity grade 3 (29.4%). Response rate was 69.9%, median PFS 11.1 months (IC 95%: 8.2-13.7), and median OS 20.2 months (IC: 15.6-20.3). Conclusions: Radical treatment for oligometastatic and unresectable NSCLC patients is a safe therapeutic strategy and it could be contemplated as an effective therapeutic alternative in selected patients.
Developmental plasticity of texture discrimination following early vision loss in the marsupial <italic>Monodelphis domestica</italic>

Behavioral strategies that depend on sensory information are not immutable; rather they can be shaped by the specific sensory context in which animals develop. This behavioral plasticity depends on the remarkable capacity of the brain to reorganize in response to alterations in the sensory environment, particularly when changes in sensory input occur at an early age. To study this phenomenon, we utilize the short-tailed opossum, a marsupial that has been a valuable animal model to study developmental plasticity due to the extremely immature state of its nervous system at birth. Previous studies in opossums have demonstrated that removal of retinal inputs early in development results in profound alterations to cortical connectivity and functional organization of visual and somatosensory cortex; however, behavioral consequences of this plasticity are not well understood. We trained early blind and sighted control opossums to perform a two-alternative forced choice texture discrimination task. Whisker trimming caused an acute deficit in discrimination accuracy for both groups, indicating the use of a primarily whisker-based strategy to guide choices based on tactile cues. Mystacial whiskers were important for performance in both groups; however, genal whiskers only contributed to behavioral performance in early blind animals. Early blind opossums significantly outperformed their sighted counterparts in discrimination accuracy, with discrimination thresholds that were lower by ∼75 μm. Our results support behavioral compensation following early blindness using tactile inputs, especially the whisker system.

Study of various modalities of treatment of internal fixation of tibial condylar fracture-schatzkers type v and type VI

Fractures of the tibial plateau usually result from high energy trauma. Fractures of the tibial plateau change the knee kinematics, alter joint stability, and cause joint incongruity. Fractures range from simple lateral condyle fractures to severe comminuted metaphyseal fractures. Various surgical modalities like open reduction internal fixation with cannulated Screw fixation, Condylar plate with or without bone graft, AO/ASIF Buttress plate (T/L) with or without bone graft, Proximal tibial locking plate have been practiced. To study the functional outcomes of various modalities of treatment of internal fixation of tibial condylar fractures schatzkers type V and type V1. To find out the basis of selecting the mode of treatment of tibial condylar fractures to bring out the best functional results. 35 patients of age group 18-70 yrs who presented with X-ray based Schatzker Type V and VI proximal tibia fractures were selected for the study. All the patients underwent Open Reduction and Internal Fixation with locking compression plating. The functional outcomes were assessed using knee society score. Complications were observed and treated accordingly with an average follow-up of 12 months. It was observed that the mean duration of the union was 14-16 weeks. Most of the patients (19) showed excellent results with a good range of motion of 122⁰. The combination of dual approaches with dual fixation and with fixed angle locking plates is a safe and effective way to have direct reduction and satisfactory fixation for complex tibial plateau fractures.
The most Applicable Physical Properties of Cervical Mucus Correlated with High Pregnancy Rate in Egyptian Cows under Heat Stress Condition

| The objective of this study was conducted to assess the potential associations between some physical properties of cervical mucus and pregnancy rate under heat stress condition. Estrous synchronization was done for 28 Egyptian cows and randomly assigned to either unheated stress group (UHS, n=14) or heated-stress group (HS, n=14). Afterward, estrus signs were observed for 30 minutes at 06:00 a.m. and 06:00 p.m. Blood and cervical mucus samples were collected (at the time of the first cervical mucus secretion) just before inseminating and to correlate the secretion pattern with pregnancy. Appearance, pH, and viscosity were observed and measured. The levels of progesterone and estradiol 17β, some biochemical profiles, and some macro-minerals levels were also determined in serum. Results showed that the percentage of cervical mucus samples that appeared transparent, thin consistency, and pH between 7-7.5 were higher in the UHS group than in the HS group. Also, estradiol, glucose, total protein, and cholesterol increase, while progesterone and sodium concentrations decrease with increasing mucus transparency and thin consistency with normal pH level (7-7.5) in both groups. It’s evident from our study that regardless of the effect of heat stress, the percentage of pregnant cows was extremely higher in cows that showed transparent vaginal fluids, and this percentage decreased in opaque fluids and reached 0.0 % with cows showed unclean mucus. Most of the serum components gained the best values of pregnancy rate when cervical mucus was transparent, thin consistency, and pH range between 7-7.5 under moderate weather conditions (UHS group). In conclusion, the appearance, viscosity, and pH of the cervical mucus are considered as useful tools in predicting the optimum time for inseminating in Egyptian cows with or without heat stress conditions.

The study clearly proves that if trust is created between the management and employees are improved then commitment will increase.
Application of Routine Analysis Procedures to a Direct Mass Spectrometry Technique: Selected Ion Flow Tube Mass Spectrometry (SIFT-MS)

In recent years the environmental and human health impacts of volatile organic compounds (VOCs) have become more apparent, resulting in increased analysis demand. The gold-standard chromatographic techniques continue to be employed for most laboratory analyses. However, they have made only modest gains in productivity over the years, and these gains are primarily due to automated sample preparation and injection. Alternatively, significant productivity gains for VOC analysis through faster sample analysis and reduced instrument maintenance could be achieved by adopting direct mass spectrometry techniques such as selected ion flow tube mass spectrometry (SIFT-MS). This article demonstrates that routine analysis techniques such as quality control checks, method validation, the method of standard additions, and internal standards are readily applied to SIFT-MS, simplifying adoption of the technique. In addition, workflows for analysis of chromatographically challenging species are simplified by using SIFT-MS. Sample throughputs are increased twoto 25-fold depending on the analytical procedure.
Cash Management and Bank’s Financial Performance: Evidence from selected Deposit Money Banks in Nigeria

This study empirically examined the effects and implications of cash management of DMBs in Nigeria. The variables studied were Cash to total asset, Operating cash to total asset, Investing cash to total asset, Financing cash to total asset, Bank size, Bank age, proxied for cash management and Return on Asset used to represent financial performance. Data used for this study were from secondary sources and were generated from the annual reports and accounts of the selected DMBs for the period 2014–2018. The results show that while operating cash to total asset of bank, investing cash to total asset and bank size have no significant effect on financial performance of DMBs, financing cash to total asset and bank age have a significant and positive effect on financial performance of deposit money bank (DMBs). However, cash to total asset has a significant negative effect on financial perfor-mance of banks. The study concludes that cash positions, which can lead to liquidity risk has to be managed because it has tendency to compound other risks. It further highlighted that adequate attention should be paid on the use and reserves of cash among banks in Nigeria. This study recommends that banks should adopt optimum cash management model for efficiency and effectiveness. Stringent regulatory policies in this regard must be reviewed in such a way that they can be relaxed, to encourage effective liquidity manage-ment measures.

Evaluation of robotic gait training in stroke through EMG investigation

Stroke is a leading cause of acquired disability in adults worldwide. To face this problem, wearable robotic exoskeletons can provide high doses, immersive gait rehabilitation, allowing an early mobilization of lower limbs in patients who are unable to maintain the upright position or trunk control. For these reasons, exoskeleton assisted gait training is nowadays proposed in addition to standard therapy to improve stroke patients re-learning. The present work aims to evaluate the impact on muscle activity of gait training assisted by the commercial wearable exoskeleton Ekso GTTM (Ekso Bionics, USA) in sub-acute hemiparetic stroke patients. Timing and amplitude of muscular activation were investigated through the Gait Metric index. Results suggested that exoskeleton-assisted therapy has been more effective than the standard physiotherapy in promoting the recovery of the non-paretic side muscular activity. These considerations support the hypothesis that Ekso training guides the re-learning process toward a healthy pattern.
