A Pressure Sensitive Occlusal Contact Indicator for Implant Restorations: An Observational Clinical Evaluation
Abstract:
Contact intensity is a significant factor in immoveable implant restorations. This study visually compares the use of four occlusal contact indicators one of which measures contact intensity and surface area in a single subject. The need for an occlusal contact indicator that can be used with fixed implant restorations is examined. Three contact indicators used in practice are visually compared to a novel system where pressure sensitive information and surface area can be evaluated numerically and stored. Findings suggest that intensity and surface area should be measured upon implant placement. Limitations of this observational study are discussed. Directions for future research and more systematic study are offered
Non-Specific Steroid Cell Tumor of The Ovary: Case Report And Review of The Literature
Abstract:
Steroid cell tumors of the ovary are particularly rare, secreting sex hormones, characterized by steroid cell proliferation and represent only 0.1% of all ovarian tumors. They are classified into three subtypes according to their cell of origin: stromal luteoma, Leydig cell tumors and a third subtype of unknown lineage corresponds to a not specified steroid cell tumor (SCT-NOS). This third subtype accounts for 60% of steroid cell tumors. The clinical manifestations of SCT-NOS can take many forms, including pain, abdominal distension, but perhaps the most visible presentations are those related to hormonal activity and virilization of the tumor. We present a rare case of a 48-year-old woman with vaginal bleeding and a history of trunk obesity, hirsutism for 2 years and hypothyroidism with hormone replacement therapy. Clinical examination revealed a characteristic of obesity, virilization. Serum testosterone was 3.62 µg / L and CA-125 was 40.67. Magnetic resonance...
Effect of Set Size and Fertilizer Type on Off- Season Onion (Allium cepa. L) Production
Abstract:
Two off-season experiments were conducted during 2015/16 and 2017/18 at Shambat Research Station Farm, Khartoum, Sudan, to investigate the effects of large (2-3 cm) and small (1-2 cm) sets size of onion variety Baftaim (S) and two chemical fertilizer (Urea 240 kg/ha) and NPK(15:15:15) (120 kg/ha) in addition to organic fertilizer (Elkhaseeb 20 tons/ha) and their combinations (Urea+ Elkhaseeb and NPK+Elkhaseeb) on off-season production. The experimental units were in split plot design, with set size and fertilizers as main and sub plots, respectively, with three replications. The yield was evaluated as bulb weight and yield/ha, whereas, the quality was evaluated as marketable and percentage of double and bolted bulbs, TSS and dry matter. The results reflected no significant differences in bulb weight due to set size, fertilizer type and their interactions, however, the heaviest bulbs were obtained by Elkhaseeb + urea and its interaction with the large set size in b...
Effects of Seed bed, Cultivars and Seed rates on Yield and Quality of Onion Sets (Allium cepa L.)
Abstract:
Field experiments were conducted during three successive winter seasons 2010/11, 2011/12 and 2012 /13, at Shambat Research Station Farm on clay loam soil pH 7.8, to study the effects of seed bed, cultivars and seed rates and their interactions on onion set yield and quality. Two seed bed (flat and ridge), two cultivars Kamleen and Baftaim (S) and three seed rates 4, 8, 12 g / m² (40, 80, 120 kg / ha) were tested. The experimental design used was 2*2*3 Factorial in spilt-split plot design with four replications. Yield was evaluated as set yield t / ha, whereas, quality was evaluated as percentage of large (2.9-2.0 cm) and medium (1.9-1.0 cm) set size according to diameter and average of single set weight (g). Cultivar Baftaim (S) gave the highest set yield t/ha and average of single set weight in the three seasons. The seed rate of 4 g/m² (40 kg / ha) resulted in highest average of single set weight and the highest number percentage of large set size...
CERN Large Hadron Collider (LHC) Radiation Source for Magnetic Resonance Biospectroscopy in Metabolic and Molecular Imaging and Diagnosis of Cancer
Abstract:
Molecular imaging is a new method in examining physiological studies in molecular dimensions. Among the various methods that have been introduced for this purpose, the magnetic resonance spectroscopy (MRS) method has made it possible to more accurately study the activities of the brain region as well as tumors in different parts of the body. MRS imaging is a type of non– invasive imaging technique that is used to study metabolic changes in the brain, stroke, seizure disorders, Alzheimer's disease, depression and also metabolic changes in other parts of the body such as muscles. In fact, since metabolic changes in the human body appear faster than anatomical and physiological changes, the use of this method can play an important role in the early detection and diagnosis of cancers, infections, metabolic changes and many other diseases.

Metallic Intrapulmonary Foreign Body by Playful Accident in A Child
Abstract:
Intrathoracic foreign bodies secondary to penetrating wounds are rare in children. We report the observation of a 10-year-old patient who presented an intrapulmonary metallic foreign body following a playful accident. Its migratory aspect, highlighted by imaging, required urgent extraction which was performed by thoracotomy, with good clinical outcome. The interest of the question lies in the circumstances of the incident, the type of foreign body and the terrain.

Success Driven: Student Motivation Actions in Teaching and Learning
Abstract:
The purpose of this topic is to add to the body of good teaching and learning that helps create the conditions for more critical thinking and practice skills that enable, keep students interested, and consistently motivate them. Teachers now have a greater focus on implementing motivational learning and studying strategies that are more relevant to the processes of teaching and learning thanks to new methodologies, which have further enhanced instructional strategies for teaching and learning. Positive school cultures that are long-lasting will result from these new methods and strategies. According to the authors, educators have been impacted by evidence-based practice and data-based decision making within the educational system. As a result, there is a growing need for educators to learn more about these resources that are relevant to students and can lead to greater success. These applicable interventions have a positive effect on students, and ...

Molecular Confirmation of Staphylococci Strain’s Identification Isolated in the Hospital and University Center of Brazzaville, Republic of Congo
Abstract:
Bacteria of the genus Staphylococcus are pathogenic Gram-positive bacteria responsible for various infections, including skin suppuration, which can be severe or chronic. The objective of this study was to confirm Staphylococci strain’s identification isolated by bacteriological methods from biological products of CHU-B patients, by molecular methods based on the analysis of the gene coding for 16S rRNA. In total, 30 strains of Staphylococci were isolated including 8 (26.66%) community strains, 22 (73.33%) hospital strains. The products of the amplification of gene fragments encoding 16S rRNA from 10 strains of Staphylococci including 6 strains of
