A novel wastewater treatment technology combining a sequencing batch biofilm reactor and biological filtration in an SBBR-BF system was presented. Elastic plastic filaments were fixed as biofilms carrying media. Particle materials (sand or anthracite) and the settled sludge constituted the filtration layer. In the laboratory studies, operating results of SBR, SBBR and SBBR-BF were compared. Better quality and stable water quality of effluent could be achieved in SBBR-BF because the fixed film and filtration layer were added in the reactor. Other laboratory experiment results indicated that slow filtration, cycle water stirring and backwashing making use of the settled supernatant are successful methods for preventing clogging and saving energy. The velocity and headloss of filtration were significantly impacted by different MLSS concentration. The MLSS concentration in the reactor must be less than 1,400 mg/L for optimal results. The average velocity of filtration ranging from 0.6 to 1.0 m/h, the backwash velocity of 10–15 m/h and the backwash time of 20 seconds are recommended according to the laboratory experiment. On-site experiment and study showed that SBBR-BF is a stable and efficient system for domestic wastewater treatment, and is particularly suited for small wastewater treatment plants, because of the simple operation and compact installation.
Comparative Study of Traditional Chalkboard Teaching Over Powerpoint Presentation as a Teaching Tool in Undergraduate Medical Teaching

Teaching and learning are active and continuous process. In the past decade, a number of developments appeared in medical education. With the advent of digitalized teaching methods, the most common teaching tool is PowerPoint Presentation. The present study, a cross-sectional questionnaire-based study, was conducted to evaluate the impact of chalkboard and PowerPoint teaching in 209 undergraduate medical students. This study has shown that blackboard teaching still remains the most preferred teaching aid by the students (71.77%) when compared to PPT teaching method (28.23%). However, the students preferred PowerPoint Presentation over traditional chalkboard, when parameters like understanding diagrams and charts (77.51%), demonstration of clinical conditions (89%), problem solving abilities (83.25%) and postlecture summarization (63.16%) were considered. On the contrary, chalkboard was the medium of choice when the students were asked about perception of subject (76.55%), stressing important points (61.72%), maintaining pace with the facilitators (61.24%), student-teacher interactions (74.64%), ability of retention (55.98%), holding attention (66.03%) and flow of thought (91.87%).
The Importance of Reporting All the Occurred Near Misses on Board: The Seafarers’ Perception

Improvement of maritime safety has previously been based on a reactive regulatory approach, where regulatory improvements have been imposed to prevent recurrence of a specific type of accidental event or accidental scenario, after such an accidental event has happened. The ISM Code requires that hazardous situations are to be reported to the company, investigated and analyzed in order to prevent future happenings. Near‐miss reporting is positively evaluated in this respect, because, near‐misses are represented experiences and mistakes that should be shared to learn from in order to prevent the occurrence of accidents. The expression “that was too close” on ships’ bridges between the master and the officers is rarely transferred to a near miss report form, preserving the probability of reoccurrence. Near misses occurred and near misses reported might present a big difference in number. Officers easily forget the near miss situation when the safety of the ship is restored. Hazards identification will be based on documented management system (SMS‐ TMSA‐ ISO). The analysis of the documented safety and quality management will address the gap in order to improve the implemented systems. The objective of this research is to find out the best practices about near‐miss reporting from the companies considered to have high level of commitment to safety within their organization. The study is based on interviews with a total of 35 seafarers who are joining on Greek ocean going vessels, and 4 representatives from safety departments of Greek maritime companies. The research also aims to address the seafarers’ perspective of reporting all near misses which have been experienced while they were in charge of specific duties (bridge watch, engine room watch) or any other operation (mooring, maintenance, drill) carried out on board. The majority of both the seafarers and the companies’ representatives believe that prior to the near miss reporting issue a safety culture environment on board is the real gain pursuit. In their perspective this is first priority to improve the general safety on board. It seems that near miss reporting is carried out on board as a compulsory compliance to the regulatory framework (ISM implementation). Further, it seems that the companies are not yet utilizing the reported data to improve feedback and the follow‐up within the organization. The authors would like to thank companies’ representatives and seafarers who have participated in this study. http://www.transnav. eu the International Journal on Marine Navigation and Safety of Sea Transportation Volume 13
Evaluation of caesarean section practices according to Robson's 10-group classification at a level two maternity ward in Conakry, Guinea

Background: The frequency of caesarean sections (CS) increased dramatically in the world over the last twenty years. The objective of this study was to evaluate caesarean section practices based on Robson classification in an urban referral hospital in Conakry, GuineaMethods: We conducted a cross-sectional study of 2,266 birthing records collected at the maternity ward of the Coronthie Communal Medical Center in Conakry, from January 1st to December 31st 2016. We included in the study all women who had a caesarean section and whose medical records were complete. Robson's classification was used to classify women into 10 groups based on maternal and fetal characteristics. The relative size of each group, its gross caesarean section rate as well as its contribution to overall caesarean section rate and the main caesarean section indications were calculated.Results: In 2016, 769 caesarean sections were performed out of 2,266 deliveries, corresponding to a hospital section rate of 33.9%. Groups 5 (11.0%), 1 (4.8%), and 3 (4.3%) of the Robson classification were the most contributors to registered hospital caesarean section rate. The main indications for caesarean section were uterine scar in group 5 and acute fetal distress in groups 1 and 3.Conclusions: The systematic reference to the Robson classification could help to identify and avoid the relative indications of the caesarean section in urban Guinea. Besides, increasing induction of labor and strengthening providers’ capacities in emergency obstetric and newborn care services could contribute to reduce caesarean section rates in Guinea.
Remote Sensing of the Atmosphere by the Ultraviolet Detector TUS Onboard the Lomonosov Satellite

The orbital detector TUS (Tracking Ultraviolet Setup) with high sensitivity in near-visible ultraviolet (tens of photons per time sample of 0.8 μ s of wavelengths 300–400 nm from a detector’s pixel field of view) and the microsecond-scale temporal resolution was developed by the Lomonosov-UHECR/TLE collaboration and launched into orbit on 28 April 2016. A variety of different phenomena were studied by measuring ultraviolet signals from the atmosphere: extensive air showers from ultra-high-energy cosmic rays, lightning discharges, transient atmospheric events, aurora ovals, and meteors. These events are different in their origin and in their duration and luminosity. The TUS detector had a capability to conduct measurements with different temporal resolutions (0.8 μ s, 25.6 μ s, 0.4 ms, and 6.6 ms) but the same spatial resolution of 5 km. Results of the TUS detector measurements of various atmospheric emissions are discussed and compared to data from previous experiments.
Family Medicine Research Productivity in Saudi Arabia for 15 Years: An Urgent Call for Action

Family medicine is one of the most vital health specialties in the field of medicine. This can be attributed to the wide range of health services for all people regardless of age, gender, and diagnosis. Saudi Arabia as suggested by various studies put more of its attention at all levels to family medicine in order to produce an adequate number of family physicians and improve both the academic aspects and the services provided by family medicine in the country. Thus, a comprehensive national survey was suggested to analyze the current situation of the specialty in the country and to draw up a strategic plan to achieve the national vision for family medicine by 2020. In light of the aforementioned, this study deemed it necessary to examine family medicine research productivity in Saudi Arabia in order to recommend possible measures to increase the quality of research output related to the field. The Web of Science (WoS) bibliographic database search engine was used to retrieve and analyze data. The terms “Family Medicine” and “Saudi Arabia” were entered in the search address fields using the SAME boolean operator (i.e., Family Medicine SAME Saudi Arabia) to retrieve records that contained these two terms and were in the same address. Research articles that were published from 1 January 2004 to 31 December 2018 were included for data analysis. Publication details such as the year of publication, document type, research area, authors’ affiliation, journal name, international collaborators, journal impact factor (JIF), and citation reports were all considered in the analysis. As for the result, Saudi Arabia’s research productivity in the field of family medicine is very poor, with a very gradual linear increase over the last 15 years. Further, health institutions have low research productivity compared to universities and medical colleges. Finally, most of the publications were published in low- or no-impact-factor journals. Therefore, this study concludes that Saudi Arabia has had low research productivity in family medicine. It recommends that an educational research program with the supervision of Ministry of Health (MOH) be implemented among family medicine physicians featuring organizational support and well-structured communication between health and educational institutions to increase research productivity in the country.
COMBINING ABILITY AND NATURE OF GENE ACTION IN OKRA (Abelmoschus esculentus [L.] MOENCH)

Nine parental genotypes of okra were crossed in complete diallel design to study combining ability and nature of gene action for earliness and yield components. Mean squares of genotypes were found to be highly significant for all studied traits, providing evidence for presence of considerable amount of genetic variation among studied genotypes. The results showed that (P5) and (P9) were the best general combiners for earliness, while (P1), (P4), (P5) and (P7) were found to be good general combiners for total yield per plant. The crosses (P5xP6), (P5xP9), (P5xP8) ang (P9xP2) were the earliest crosses in comparison with the other crosses. Meanwhile, the cross (P1xP9) had the highest mean value for fruit diameter, plant height and fruit weight. In addition, the crosses, (P1xP6), (P1xP7), (P5xP9) and (P6xP4) had the highest mean values for No. of fruit/plant and total yield /plant. Therefore, these promising crosses among F1 hybrids and F1 reciprocal (F1r) combinations could be used for further breeding studies to improve the economic traits in okra. The results revealed that the general combining ability (GCA) and specific combining ability (SCA) mean squares were highly significant for all studied traits. Significant reciprocal effect mean squares were observed for all studied traits, indicating that these traits were controlled by extra-nuclear factors as well as nuclear factors. The results indicated that the magnitude of additive genetic variance (σ 2 A) were positive and lower than those of non additive (σ 2 D) one for most of studied traits, indicating that non additive gene action played a major role in the inheritance of these traits. The broad sense heritability estimates (H 2 b %) were more than 75% and larger than their corresponding narrow sense heritability (H 2 n %) for all studied traits. However, estimates of narrow sense heritability were 13.9%, 32.4, 40.5, 47.1, 76.8 for earliness, fruit length, fruit weight, plant height and fruit diameter, respectively. The estimates of narrow sense heritability ranged from 11.3 % to 17.34% for total fruit yield per plant and No. of fruit per plant, respectively. It could be concluded that the most studied traits were mainly controlled by non additive effects and cytoplasmic factors. Therefore, the genetic material used in this study could be used for hybridization for producing promising crosses to improve economic traits in okra.
Immunohistochemical detection of Def6 protein in oral cancer

Nowadays oral cancer had become global health issue and reach 21st rank in Malaysian population. Def6 or IRF-4-binding proteins (IBP) that are mostly produced in lymph node and thymus are associated with cell survival and cell proliferation. Def6 protein expression is often found in autoimmune diseases, but current studies also found Def6 in some cancers. In this study, we would like to detect Def6 protein expression in oral cancer. 36 formalin-fixed paraffin embedded tissue were selected for both test group (oral cancer) and control group (normal oral mucosa). The cases were retrieved from the archives of faculty of dentistry, University of Malaya, Kuala Lumpur. Immunohistochemistry (IHC) staining was manually performed using Def6 antibody (Abcam 1:300) and assessed quantitatively (positivity and staining intensity). Positive and negative controls were used to validate the IHC run. All data were then analysed using SPSS version 25.0. Control group is negative for Def6 expression. 29 cases (82.86%) of oral cancer were Def6 positive with 2.86% weak staining, 5.71% moderate staining and 74.28% had strong staining intensity. There is significant different between Def6 expression in normal oral mucosa and oral cancer ( p <0.05). Thus, we postulate that Def6 expression plays a big role in carcinogenesis of human oral cancer.
On the Properties and Applications of a Transmuted Lindley-Exponential Distribution

The Quadratic rank transmutation map proposed for introducing skewness and flexibility into probability models with a single parameter known as the transmuted parameter has been used by several authors and is proven to be useful. This article uses this method to add flexibility to the Lindley-Exponential distribution which results to a new continuous distribution called “transmuted Lindley-Exponential distribution”. This paper presents the definition, validation, properties, application and estimation of unknown parameters of the transmuted Lindley-Exponential distribution using the method of maximum likelihood estimation. The new distribution has been applied to a real life dataset on the survival times (in days) of 72 guinea pigs and the result gives good evidence that the transmuted Lindley-Exponential distribution is better than the Lindley-Exponential distribution, Exponential distribution and Lindley distribution based on the dataset used.
Calculation of inductances and induced currents in cryogenic by-pass line for SIS100 particle accelerator at FAIR

Quality of electric current delivered to the magnets of a particle accelerator is essential for safety and reliability of its operation. Even small discrepancies strongly affect the properties of particle beams. One of the sources of the disturbances is the appearance of induced currents caused by the electromagnetic interactions between the elements of the machine. In this paper the calculations of induced currents in by-pass lines of a SIS100 particle accelerator are presented. In order to find the values of the currents the self-inductances and mutual inductances of the by-pass lines are found. Due to the complex geometry of the line, especially of Ω-shaped dilatations, the numerical approach was employed. The calculations show that the size of induced currents increases with the distance between the cables in an individual bus-bar. The maximum discrepancy of the magnetic field in a dipole magnet is found to be 7.7 μT. The decrease of distance between the cables allows one to obtain a discrepancy of 1.2 μT.
Influence of Certain Animal Manures on Nematode Community in Mandarin Orchards Citrus reticulata (Blanco) in Sharkia Governorate, Egypt

The effects of cow, horse and turkey manures in comparison with oxamyl on phytoparasitic, free-living and predacious nematodes were verified in a mandarin orchard located in Sharkia Governorate during 2017. Treatments of cow and horse manures were at the rate of 6.4 tons/ feddan, while that of turkey manure was at the rate of 4.8 tons/ feddan. However, oxamyl 10% G was treated at the rate of 25 kg/ feddan. Samples were taken monthly during three months after application. Soil temperature and pH were measured after sampling. Results indicated that the tested manures and oxamyl significantly (P ≤ 0.05) minified numbers of phytonematodes. The best treatment (after oxamyl) was turkey manure followed by horse manure, while cow manure was the least effective one. Remarkable decrease in numbers of plant-parasitic nematodes was noticed as the time elapsed after application. For instances, in turkey manure treatment percentages reduction in numbers of Tylenchulus semipenetrans, Pratylenchus spp. , Tylenchorhynchus spp. , and Helicotylenchus spp. after 2 and 3 months were diminished by 56.78% (75.29%), 57.66% (78.54%), 56.84% (77.95%) 56.23% and (78.28%), respectively. On the other hand, one month after application, the tested manures slightly increased numbers of free-living nematodes mainly genus Rhabditis and predacious nematodes belonging to order: Mononchida. Whereas, 2 and 3 months after application pronounced abundance of these nematodes was detected. The highest augmentation was achieved in soil amended with turkey manure. However, oxamyl decreased numbers of nonstomatostylet bearing nematodes compared to untreated trees. The tested manures raised soil temperature and altered soil pH to be alkaline. Generally, our results emphasized the significance of animal manures particularly the turkey one in suppression plant-parasitic nematodes in mandarin orchards which may be attributed to its role in increasing predacious nematodes and change soil temperature and pH.
Parametric Human Shape Reconstruction via Bidirectional Silhouette Guidance

We present a method to reconstruct the body geometry of a person by aligning the skinned multi-person linear (SMPL) model to an unconstrained human image. In contrast to previous methods that regress the model parameters from a shared image feature, we decouple the regression of pose and shape parameters in two sub-networks so that we can use different backbone architectures to extract better and more specific features for each regression task while allowing the two sub-networks to work together by our final training loss. We have further proposed a novel bidirectional silhouette constraint to restrict the estimated body geometry. The silhouette constraint is weighted adaptively according to the accuracy of pose estimation in order to handle truncations, occlusions and complex human poses. Experimental results on Human3.6M and UP datasets show that our method outperforms state-of-the-art methods and fits the body segmentation better, especially under extreme human pose conditions.
2. Omogoriola, H.O Article

Oil industry activities such as exploration, transportation, storage, use and disposal, as well as oil spills are sources of major contamination problems in Niger Delta, which have significant deleterious effects on aquatic organisms. The objective of this study was to report LC values 50 obtained from acute toxicity tests on the African Catfish, C. gariepinus exposed to Water Accommodated Fraction (WAF) –heavy (Ebok), light (Meji) and medium (Erha) crude oils. Acute toxicity concentrations of 0%, 2%, 4%, 6% and 8%, 0%, 15%, 20%, 25% and 30% and 0%, 40%, 60%, 80% and 100% were used to determine the 96h Lethal Concentration (LC ) of 50 heavy, light and medium crude oils respectively. The analysis of variance (ANOVA) showed that there was a significant (p<0.05) difference in the quantal response of C. gariepinus to different concentrations of the various crude oil types at 24, 48, 72 and 96 hours exposure. These results showed that 96LC values for heavy, light and medium crude oils on C. 50 gariepinus were 0.028 mg TPH/l, 0.177 mg TPH/l and 0.742 mg TPH/l respectively. The 96LC of WAF showed that the heavy crude oil was six times more toxic than light and twenty 50 six times more toxic than medium and on toxicity categorization, the heavy, light and medium crude oils were very highly toxic, highly toxic and highly toxic on C. gariepinus. Based on the 0 acute toxicity tests, heavy with lower API (<22.3 C) gravity was more toxic than other crude oils on C. gariepinus. All crude oils are toxic to aquatic organisms especially the fish; their discharge into the water bodies during crude oil exploration, transportation, storage and even sabotage should be discouraged to protect the environment.
Outcomes of patients with malignant melanoma treated with immunotherapy prior to or after vemurafenib.

8569 Background: Treatment of patients (pts) with BRAF mutant malignant melanoma (MM) with vemurafenib (vem), a BRAF inhibitor (BRAFi), is associated with a high response rate (RR) and improvement in progression free survival (PFS) and overall survival (OS) compared to standard chemotherapy. Responses to vem are typically not durable and most pts require additional therapy. However, there is little data to guide sequencing of vem with other standard therapies such as ipilimumab (ipi) or interleukin 2 (IL-2). Methods: 43 pts treated with vem as part of clinical trials from 2009-2012 were retrospectively identified. RR of vem was calculated for all pts as well as for pts treated with immunotherapy (IT) prior to vem. The OS from first systemic and vem treatment, duration of vem therapy, OS from when pts came off vem, and PFS and OS for post-vem ipi was determined using Kaplan-Meier estimates. Results: Of the 43 pts, 11 remain on vem and 32 are off vem (19 deceased) with a median follow up of 19 mo. Pre-vem L.
