Effects of Using Anode Biofilm and Cathode
Biofilm Bacteria as Inoculum on the Start-up,
Electricity Generation, and Microbial Community
of Air-Cathode Single-Chamber Microbial
Fuel Cells

Inoculum is critical for the start-up and performance of microbial fuel cells (MFCs). The effluent of mature MFCs is usually used as inoculum for the start-up of immature MFCs. However, the effluent of mature MFCs contains bacteria both from anode biofilm (ASB) and cathode biofilm (CSB). Here, ASB and CSB and their mixtures were used as inoculum in the start-up of MFCs in order to gain more insight into the influence of CSB on the start-up of MFCs. Compared to anode inoculum-enriched MFCs, using cathode inoculum reduced start-up time from 5 d to 3 d. The time needed for scavenging oxygen was reduced from 900 min to 600 min, maximum power density was 19% lower (691 mW/m2 vs 823 mW/m2), and the charge transfer resistance increased from 29.0 Ω to 48.3 Ω. The decreased start-up time and power generation of cathode inoculum-enriched MFCs was attributed to the increasing abundance of Azospirillum (80.02% vs. 12.68%) and the decreasing abundance of Geobacter (9.08% vs. 61.25%). This research suggested that CSB in the effluent of mature MFCs, when used as inoculum, has a side-effect on the start-up of MFCs.
An ontology-based hybrid methodology for image synthesis and identification with convex objects

ABSTRACT One of the core challenges in developing a computer system for machine learning is to make the system learn efficiently and effectively like a real human by grasping the domain knowledge exemplified by human experts. In this challenge, we have introduced a hybrid image synthesis model that can simulate one of the human’s learning capabilities in the vision field – the ability to synthesize images of convex objects by identifying solid geometries and textures of specific objects using few photographs. We have incorporated an ontology-based, domain knowledge on solid geometries into our model to synthesize large number of training images with only a minimum number of input images. Our initial experiments have shown that our model has convincing improvements by demonstrating a substantially better FAR/FRR/EER results when it is compared with a smaller set of non-synthetic images.
Does Foreign Direct Investment Generate Long-Term Growth in Ghana?

In pursuant to sustainable economic growth on the ticket of FDI-led growth hypothesis, the government of Ghana has instituted a myriad of thoughtful policy reforms to help boost the economy to realize a self-sustaining economic growth. To some extent, the policies might have paid off as the country was named the highest recipient of FDI in West Africa in 2018. However, the supposed upsurge in the inflow of foreign direct investment in the country and its expected long-run spillover benefits have not been tangibly felt in the region as the economy continues to oscillate. Therefore, this study utilized two methods; the autoregressive distributed lag model (ARDL) and the variance decomposition method (VDM) to empirically examine economic growth of Ghana as a function of foreign direct investment (FDI) whiles controlling for exchange rate, financial development, trade oppeness and employment rate. The results of the study endorses the FDI-led growth for Ghana by indicating that a positive long run causal impact flows from FDI to economic growth. The findings from the VDM test affirm the results are robust and reliable. Therefore, the study suggests that government should amplify FDI inflow via policies like incentives to draw more foreign investors directly into other sectors other than the conventional sectors gratified by foreign investors.
Training on Functional Behavioural Analysis on Teacher Self-E cacy Among Special Education Teachers in Osun State, Southwestern Nigeria

Dealing with challenging behaviour is a source of stress and burnout among teachers of children with special education needs. Functional Behavioral Analysis (FBA) is useful for prevention and management of challenging behaviour, but the evidence-base among special education teachers is limited in Sub-Saharan Africa. Twenty teachers were recruited from two special needs schools (10 from each school), with one school designated ‘intervention’ and the other ‘control’. Two sessions of group-based training on FBA were conducted in the intervention school for the 10 teachers. All participants completed the ‘Teacher Self E cacy Scale’ and ‘Professional Quality of Life Scale’ at baseline and again two weeks after the last intervention session. e intervention group completed a post-intervention ‘Client Satisfaction Questionnaire’. Controlling for baseline scores, the intervention group scored signi cantly higher on Self-E cacy [F (1,18)=8.95, p=0.009, partial eta squared=0.36], and lower on Burnout [F (1,17) = 9.82, p=0.006, partial eta squared=0.380]. e intervention group’s mean score on the Burnout subscale of PQOLS was more than one standard deviation lower than the control group after the intervention [(29.30(2.58) vs 34.11(4.01)]. All participants in the intervention group rated the programme as good or excellent and over three -quarters (77.7%) would recommend it to their peers. To our knowledge, this is the rst study of FBA training for special education teachers in Sub-Saharan Africa. e programme showed promising e ectiveness, good feasibility and was highly accepted. 2L V K UJ[PVUHS )LOH]PV YHS (UHS P :WLJPHS ,K JH[PVU 5LLK ) YUV [ ;LHJOLY 5PNLYPH e E ect of Training on Functional Behavioural Analysis on Teacher Self-E cacy Among Special Education Teachers in Osun State, Southwestern Nigeria Olanrewaju Ibigbami1, Yetunde Adeniyi2, Olayinka Omigbodun3 and Cornelius Ani 4 LWHY[TLU[ VM 4LU[HS /LHS[O 6IHMLTP ( VSV V UP]LY P[ 0SL 0ML HUK VU S[HU[ OPSK HUK (KVSL JLU[ 7 JOPH[YP [ L SL .

Deterministic and Stochastic Holling-Tanner Prey-Predator Models

A modified version of the so called Holling-Tanner prey-predator models with prey dependent functional response is introduced. We improved some new results on Holling-Tanner model from Lotka-Volterra model on real ecological systems and studied the stability of this model in the deterministic and stochastic environments. The study was focused on three types of stability, namely, stable node, spiral node, and center. The numerical schemes are employed to get the approximated solutions of the differential equations. We have used Euler scheme to solve the deterministic prey-predator model and we used Euler-Maruyama scheme to solve stochastic prey-predator model.
CCIDE_A_324396 379..387

Dental Clinics, Dental University Hospital, King Saud University, Riyadh, Kingdom of Saudi Arabia Objective: To evaluate the ability of dentists and dental students to detect caries by using the International Caries Detection and Assessment System (ICDAS). Materials and Methods: A cross-sectional study was conducted in Riyadh city and in the College of Dentistry at King Saud University (KSU) in Saudi Arabia. The study sample included a cluster sampling of 50 private clinics (100 dentists) and all 3rd-, 4th-, and 5th-year students (393 students). Data were collected using an electronic questionnaire. The ability score of detecting caries for each group was identified by calculating the mean percentages of the score. The data were entered into SPSS Version 20. One-way ANOVA was used for comparing quantitative data. Results: The overall response rate of the survey was 64.5% (318/493). A total of 62.6% (199) of respondents know about ICDAS. All groups had difficulty assessing the activity of caries in Code 2. There were significant differences among all groups in the ability to detect caries (P-value: 0:00). Moreover, 4thand 5th-year students had the highest mean of percentage ability score (53.8% and 57.6%, respectively) to detect caries using ICDAS compared to 3rd-year students and general practitioners (38.6% and 38.7%, respectively). Conclusion: Overall, detection of early dental caries limited to enamel was confusing and difficult. The abilities of dentists and dental students to detect caries using ICDAS were low and require improvement by continuing further clinical training.
White magnetic paper based on a bacterial cellulose nanocomposite

A newly proposed idea for the fabrication of white magnetic paper is presented. These papers are fabricated from a layered composite of bacterial cellulose (BC) sheets. Magnetic BC sheets are prepared by the incorporation of CoFe2O4 nanoparticles (NPs) in the BC structure (MBC). White BC sheets were formed by the impregnation of ZnO NPs in the BC nanofibrils (ZBC), and then forming a ZBC/MBC/ZBC sandwich structure. This structure was then hot-pressed to obtain white magnetic paper. The fabricated magnetic BC paper exhibits a ‘whiteness’ of over 80%, with a high reflectance of over 70% in the visible spectral range. XRD and SEM analysis confirmed the presence of the BC, CoFe2O4 and ZnO phases in the white magnetic paper. The whiteness of the paper is improved further with a higher concentration of ZnO NPs, but at the cost of a reduction in the mechanical properties. Magnetic hysteresis was observed in the fabricated white magnetic paper with a saturation magnetization of ∼20 emu g−1, comparable to the literature values for black magnetic papers. The white magnetic paper was demonstrated to exhibit flexibility and foldability just like regular paper sheets but can also be distinguished by subjecting it to an external magnetic field. This gives potential for its use as security paper or in anti-counterfeiting applications.
The Baetidae (Ephemeroptera) of the Comoros and Mayotte

Material collected in 1974 during the Austrian Hydrobiological Mission of F. Starmühlner to the Comoros and during recent years by one of the authors (NM) in the course of an ongoing freshwater monitoring program in Mayotte is the basis of this first larger study of the mayfly family Baetidae in the Comoros Archipelago (Comoros, Mayotte). We identified eight different species using morphological characters, four species on both the Comoros and Mayotte, three species on the Comoros only and one species on Mayotte only. Two species, Dabulamanzia mayottensis sp. nov. and Nigrobaetis richardi sp. nov., are new to science; they are described and illustrated based on their nymphs. The nymph of Afroptilum bicorne (Ulmer, 1909) is described for the first time and its assignment to this species is discussed. The description of the previously endemic Malagasy species Potamocloeon (Aquaediva) freitagae (Gattolliat, 2001), is complemented based on the additional material from the Comoros and re-examination of the type material. A key to the nymphs of all species of Baetidae in the Comoros and Mayotte is provided and the biogeography of the family in this region is discussed.
Finite Element Analysis of Experimentally Tested Concrete Slabs Subjected to Airblast

Since the last century, concrete has been used to protect structures against intentional or accidental detonation of explosives. Recently, as concerns about terrorist activities and accidents in plants using explosives increase worldwide, the study of the behaviour of this type of material and any civil or military structure under the influence of explosions has increased. Among the lethal effects of explosive devices, which cause greater loads in structural elements is the airblast effect. For this reason, this paper presents a series of airblast finite element (FEM) simulations developed in Abaqus/Explicit®. To validate the computational method, such simulations are geometrically and structurally kept similar to full-scale tests conducted in a blast test area of the Science and Technology Aerospace Department (Brazilian Air Force). Both simulations and tests consisted of seven reinforced concrete slabs with compressive strengths of about 40 to 60 MPa, variable steel reinforcement areas, slab dimensions measuring 1×1 m, and subjected to 2.7 kg of non-confined plastic bonded explosive. The results demonstrated that FEM simulations can predict the rupture of the tested slabs and how the effect occurs, showing a valid method to investigating the response of RC slabs when compared to expensive field tests. Differences in displacements were observed between the results of FEM simulations and blast field tests, mainly caused by the sensitivity of the case studied, limits of computational capacity, and intrinsic variations in the materials and sensors used in the field tests. However, these differences showed an order of magnitude compatible with the safety coefficients used with RC, demonstrating that the method can be used for the design of RC slabs under the effect of airblast.
Recycling flue gas desulphurization gypsum (FGDG) for removal of tetracycline from aqueous solutions

ABSTRACT The present research aimed to explore the feasibility of removing tetracycline (TC) by flue gas desulphurization gypsum (FGDG). The adsorptive properties of FGDG for TC, such as pH values, adsorption isotherms and kinetics, and thermodynamics parameters, were investigated in the batch experiments. The results revealed that the process of TC adsorption was pH dependent and the optimal pH value was pH 8.0. The adsorption mechanism could attribute to the formation of TC-FGDG complexation. Langmuir isotherm model and the pseudo-second-order kinetic model can be described the better adsorption behaviors. The thermodynamics parameters indicated that adsorption process was endothermic and chemisorption in nature. FGDG would be an ideal adsorbent for removal of TC from aqueous solutions with the characteristics of low-cost and good adsorption properties.
Effect of Chain Length and Topological Constraints on Segmental Relaxation in Cyclic PDMS

We present a detailed investigation of local dynamics of linear and cyclic poly(dimethylsiloxane) (PDMS) covering a wide range of molar masses. To aid interpretation of the experimental data, QENS measurements in the time scale from 2 to 200 ps and at Q = 0.3 to 1.8 A–1 are complemented by theoretical calculations. These make use of a methodology developed by us elsewhere applicable to both simple chain models and real chains and applied here, for the first time, to cyclic PDMS. Analysis of the incoherent dynamic structure factor at T < Tm shows that the rotational motion of the methyl groups is unaffected by polymer topology. At higher temperatures, the QENS data are described by a model that consists of two dynamic contributions: methyl group rotation and segmental motion, the latter described by a stretched exponential function. Relaxation times of both linear and cyclic PDMS increase with increasing molar mass. Several features predicted by theory are also reproduced by the experimental data. We show,.
Application of a Model-Based Fault Detection Approach on a Spacecraft

The model-based fault detection approach is one of the software-based supervision systems monitoring. This method has a marked effect to detect components fault without demanding extra sensors to measure or add redundancy. The extended multiple model’s adaptive estimation method is an online strategy to detect and isolation failure of components. Simple implementation, fast and accurate response, compatibility with nonlinear systems, and the ability to detect different types of faults are the most important features of this method. This method is applied to the faulty spacecraft in terms of actuators and its capability is evaluated. The most probable actuator fault implemented using MATLAB/SIMULINK software. The presented approach successfully detects faulty actuators.
Bone Health in Patients With Prostate Cancer: An Evidence-Based Algorithm.

Background The veteran population has an increasingly high number of patients who have either survived, are currently living with, or are being treated for prostate cancer. Survivorship concerns related to the treatment of this disease is a relevant topic in the Veterans Health Administration, given the longevity of life with localized disease treatment and the fairly durable therapies for metastatic disease. Long-term androgen deprivation therapy (ADT) forms the backbone of treatment for advanced and metastatic castration-sensitive prostate cancer. Observations The potential bone-health complications resulting from treatment with ADT should be recognized as many patients live for prolonged periods with stable or controlled disease. It is well established that prolonged ADT can lead to significant bone loss and increased fracture risk, which increases all-cause mortality and disability. Bone-remodeling agents, such as bisphosphonates and receptor-activated nuclear factor κ-B ligand inhibitors, are recommended to reduce the risk of fragility fractures in patients at high risk due to diminished bone density while on hormone deprivation therapy for hormone-naive prostate cancer. These agents are also indicated at a higher dose to prevent complications from bone metastases in castration-resistant prostate cancer with bone metastases. Conclusions This article reviews recent studies on bone health in men with prostate cancer and presents an evidence-based algorithm for bone-health monitoring during treatment and recommended interventions.
The Determination of Total Alkaloid, Polyphenol, Flavonoid and Saponin Contents of Pogang gan (Curcuma sp.)

Pogang gan (Curcuma sp., Zingiberaceae family) is medicinal herb and threatened and it is usually used as a tonic. We successfully micropropagated and cultivated this species. This study determined the total alkaloid, polyphenol, flavonoid and saponin contents of its growth time in order to determine harvest time. The highest level of total alkaloid content is roots after 11 months cultivation (0.272 mg/g), total polyphenol content is rhizomes after 11 months (1.71 mg GAE/g), total flavonoid content is rhizomes after 11 months (13.89 mg QE/g) and total saponin content is tubers and roots after 11 months (5.26% and 4.78%). The total content of alkaloid and flavonoid of pogang gan is higher than Curcuma zedoaria. The total saponin content of natural pogang gan is equal to 39.5% of 6-year old Vietnamese ginseng and the saponin content in rhizomes and tubers of 11-month-planted Pogang gan is from 55.5% to 67.8%, compared with natural Pogang gan.
Seismotectonics in Northeastern France and neighboring regions

The region of northeastern France is affected by low-magnitude background seismicity, with the rare occurrence of moderate earthquakes, which gives this region a non-negligible seismic risk. We provide an overview of the seismicity and seismotectonics of this intraplate domain and of its subregions: the Upper-Rhine Graben (URG), the external range and foreland of Jura, the Vosges, northern France and southern Belgium. Previously published catalogues over historical and instrumental times are used, and the epicentral distribution of earthquakes is compared to known tectonic structures, and the recently computed deformation field. Although no large earthquakes with Mw > 6.0 occurred since the 1356 Basel seismic event (Io IX, MKS), the recent identification of active faults suggests periods of high seismic strain rates in the past. The origin of the seismic activity in each of these sub-regions, characterized by low to very-low strain rates, is attributed to pre-existing faults reactivated under specific natural or anthropogenic conditions.

Physicochemical and Microbiological Characteristics from “Wagashi” Production Whey in Abomey-Calavi (Benin)

Aims: The production of “wagashi”, induce the production of whey which is often directly drop in the environment. The aim of this study was to evaluate the microbiological and physicochemical qualities of wagashi’s whey samples collected in Abomey-Calavi (Benin). Methodology: Whey samples were collected from Abomey-Calavi (Parana and Akassato) in Southern Benin. The physicochemical analyses targeted the pH, titratable acidity, dry matter contents, protein and lactose. The microbiological analyzes carried out consisted in enumeration of total mesophilic flora (TMF), fecal coliforms, lactic acid bacteria, staphylococci, yeasts and molds, Pseudomonas, Escherichia coli and salmonella by cultures on specific synthetic nutrient media. Results: This study revealed characteristics such as dry matter (5.30-5.66 g / l), pH (3.91-5.21), titratable acidity, protein (5.94-0.128 g / l), lactose; and microbial quality of the whey. Parana’s whey was more acidic (pH = 3.91 ± 0.014) than Akassato’s whey analyzed with higher titratable acidity (pH = 0.92 ± 0.01). The presence of total mesophilic aerobic flora, Escherichia coli, staphylococci, lactic acid bacteria, yeasts and molds reveals fecal, human and environmental contamination during cheese production or during whey storage. Thus, Parana's whey was more contaminated with TMF (3.45.108 CFU/ml), lactic acid bacteria (4.82.108 CFU/ml) and fecal coliforms (> 3.108 CFU/ml) while Akassato's whey was more contaminated by staphylococci (4.70.108 CFU/ml) and Escherichia coli (> 3.108 CFU/ml). Salmonella was not identified. Conclusion: It thus important raising the awareness of cow's milk processors and / or whey producers in Benin. We therefore project to use this whey as a substrate for bioproduction.
DESIGN OF MIMO/SMART ANTENNA ARRAYS USING DIFFERENT ARRAY MODULES FOR HANDHELD DEVICE

|In this paper, an eight-element MIMO smart antenna system consisting of two diﬀerent array modules for handheld device is proposed. The (cid:12)rst module is a six-element array operating in N78 (3.3{3.8 GHz) band for 5G, which achieves MIMO functions for receiving and beam scanning for transmitting. The second module is a two-element antenna array, which operates in LTE/WWAN/N78 (0.7{0.91 GHz, 1.63{2.61 GHz, 3.3{3.8 GHz) bands. To take full advantage of the existing antenna resources in the mobile device, the six elements in the (cid:12)rst module are combined with the two elements in the second module to form an 8-element array in the overlapping N78 band. Good isolations and envelope correlation coeﬃcients are achieved in the receiving mode by loading L-shaped slots for the combined module. The distribution of excitations for the combined array in the transmitting mode is optimized by the method of maximum power transmission eﬃciency to direct the beam to the desired direction with maximum possible gain and is realized by an in-house designed beamforming controller. The impacts of the environments on the antenna array performance are investigated.
