Roadside Air Pollution Assessment in Port-Harcourt, Nigeria

In this study, the level of air pollution along roadsides at selected locations in Port-Harcourt metropolis was assessed. The ambient air quality survey was done with respect to Carbon monoxide, Sulphur dioxide, Oxides of nitrogen and Particulate matter (PM10) and monitored in the study area at four locations. Three junctions (Mile One Junction, Rumuola Junction and Artillery Junction) along the Port-Harcourt Aba Expressway were monitored because of their high traffic density and the presence of roadside vendors while Bodo Street in the New GRA was used as the control. The air pollution measurements were carried out using direct reading, automatic in-situ gas monitors; HAZDUST Particulate Air Monitoring Equipment for PM10, VRAE Multi Gas Monitor for SOx and NOx and AEROQUAL Gas Detector for CO. Sampling was carried out for six consecutive days; three days for each location. The measured parameters were found to be in the following ranges for hourly readings: CO (0-60.24ppm), NOx (0-1.5ppm), SOx (0-0.75ppm) and PM10 (26-199μg/m). Air Quality Index values in the study varied between a maximum of 267.17 and a minimum of 14.71 showing that the health of people who spend long hours along roadsides are at risk.
Outcome of Unstable Pelvic Fractures after Internal Fixation: Our Experience

Introduction: Pelvic Fractures are usually associated with high intensity trauma, as those seen in traffic accidents. These patients present at emergency department as polytrauma and unstable pelvic fractures which has a very high mortality and even higher morbidity. Internal fixation surgery in an integral part for its management allows for a better outcome. Material and Methods: Fifteen patients with unstable pelvic fractures after traffic accidents, treated with internal fixation surgery between 2012 to 2018 were retrospectively reviewed. Every patient had a Tile B or Tile C fracture and was followed up at a minimum of 6 months. The outcome was performed according to Survey form 36v2, Majeed pelvic score, Iowa pelvic score, Pain Visual analog score. Results and Discussion: The average age was 48 years old and a mean follow up time of 30 months. Sixty percent had a Tile C fracture and the mean time between admission and discharge was 31 days. The mean time between admission and surgery was 13 days. Seven patients were female and 8 patients were male. The main cause of the fracture and run over accidents and motorcycle accidents. The mean score for physical SF36v2 was 60% and emotional SF36v2 was 54%. The mean VAS pain score was 3.7/10 and more than half didn’t limp at final observation. The mean Majeed pelvic score was 81% and Iowa pelvic score was 70.5%. Conclusion: The outcome of unstable pelvic fracture after internal fixation was very good with a Majeed pelvic score of 81%.
Efficient Method for Direct Embryogenesis in Phalaenopsis Orchid

Light spectrum is one of the environmental cues that influence plant growth and development. Light is a stimulating factor for induction of somatic embryos during tissue culture practices. To accelerate the direct embryogenesis, six different light spectra including: white (W), red (R), blue (B), green (G), red + blue (R+B) and red + far red (R+FR) together with dark condition (D), in combination with thidiazuron (TDZ) in four concentrations (0, 0.5, 1.5 and 3 mg L-1) were used. Inter-simple sequence repeat was used for identification and genetic stability analysis of somatic regenerated plantlets. Intact protocorm explants showed higher potential for direct somatic embryogenesis (DSE) than the other explants. The rate of DSE was highly dependent on the concentration of TDZ and its interaction with light spectra. R and R + FR spectra with 3 mg L-1 TDZ on intact protocorms and R+FR with 3 mg L-1 TDZ were efficient treatments to induce DSE without somaclonal variation. G light spectrum has also significant effects on DSE of protocorm explants. The amplified products showed 26 scorable bands and regenerates were completely identical to the mother plant. In conclusion, this protocol provides way to regenerate plants through embryogenesis, and is a reliable protocol to obtain proper development and genetic stable Phalaenopsis embryos.
Time Series Clustering Based on the K-Means Algorithm

Time series is one of the forms of data presentation that is used in many studies. It is convenient, easy and informative. Clustering is one of the tasks of data processing. Thus, the most relevant currently are methods for clustering time series. Clustering time series data aims to create clusters with high similarity within a cluster and low similarity between clusters. This work is devoted to clustering time series. Various methods of time series clustering are considered. Examples are given for real data.
Optimization of the High Aspect Ratio Wing with Position and Distribution of Aileron Mass on the Speed and Frequency

As the aileron mass parameter and its position on the velocity and frequency of the flutter is an important problem in design of the aircraft wings, the optimization of the composite wing with an aileron is represented in this paper. Mass properties and its distribution have a great influence on the multidisciplinary optimization procedure based on speed and frequency of flutter. At first, flutter speed was obtained with and without aileron, then aileron was mass-equilibrated and other studies were performed using the proposed method. It is deduced that changing the position and mass properties of the aileron the speed and frequency of the flutter changed. The position of the aileron was determined for better wing performance in flutter instability and minimizing the composite stress. In the present study, it has been attempted to model the aerodynamics of the problem under ultrasound with the panel method, and the structure has been modeled using finite element method and coupled with the aerodynamics. Using the p-k method, the equations are solved and the results are extracted.
Evolutes of null torus fronts

The main goal of this paper is to characterize evolutes at singular points of curves in hyperbolic plane by analysing evolutes of null torus fronts. We have done some work associated with curves with singular points in Euclidean 2-sphere [H. Yu, D. Pei, X. Cui, J. Nonlinear Sci. Appl. , 8 (2015), 678–686]. As a series of this work, we further discuss the relevance between singular points and geodesic vertices of curves and give different characterizations of evolutes in the three pseudo-spheres. c ©2015 All rights reserved.
OXIDATIVE STABILITY OF PROCESSED CHEESE SPREADS AS AFFECTED BY ADDED WHEY PROTEINS/

The effect of added whey proteins/carrageenan particulate on the oxidative stability of processed cheese spreads was investigated. Processed cheese spreads (low fat, half fat and full fat) containing different levels of whey ptoteins/carrageenan particulate, (0, 2, 4 and 6%) were prepared. Spreads from different treatments were analysed for gross composition (TS, fat, TN and SN, lactose and acidity), SH groups, thiobarbeturic acid (TBA) values and conjugated dienes during a storage periods of 90 days in the refrigerator. Addition of particulates increased slightly the SH group contents of spreads with the increase in percentage of particulates added. However, the SH groups in spreads decreased with advanced storage. The TBA values of spreads increased slightly with advanced storage. However, the effect of added particulate on TBA values was negligible. On the other hand, the conjugated dienes contents increased with the increase in fat content in spreads and with advanced storage in all treatments. However, the increase in dienes in full fat spreads during storage was less pronounced in spreads containing high percentage of particulates. This suggests the whey protein particulate may have beneficial effect on the oxidative stability of full fat processed cheese spreads.
Pre-service Teachers’ Emotional Social Intelligence: Differences by Gender and Major

The current study examines pre-service teachers’ emotional social intelligence with regard to their gender and major. Data was gathered from a faculty of education students majoring in preschool education, secondary school mathematics education and secondary school biology education (N=230). To collect data, Emotional Quotient Inventory (the EQ-i) was used. A two-way ANOVA was conducted to examine the effect of gender and major on total EQ-i scores. A significant main effect was found for major, indicating that the scores of preschool pre-service teachers were lower than the scores of both mathematics pre-service teachers and biology pre-service teachers. To explore the effects of gender and major with respect to subscales of EQ-i, a two-way MANOVA was performed. Results of this analysis yielded significant main effects for gender and major. Findings will be discussed in the light of previous research.
Studies on the Interaction between Derivatives of 9-Aacridinyl Amino Acid as Anticancer Drugs and Functionalized Carbon Nanotubes: ONIOM2-PCM Approach

Recently, the derivatives of 9-acridinyl amino acid have been synthesized and introduced as the anticancer and antiproliferative agents. In this regard, the functionalized single-wall carbon nanotubes (f-SWCNTs) have been employed as a drug delivery system in the nanomedicine applications. The role of the functionalized armchair (5, 5) SWCNT in drug delivery of 9-acridinyl amino acid derivatives as anticancer agents was studied by combining quantum mechanics and molecular mechanics methods. Therefore, the present study was conducted to investigate and measure the binding properties of 9-acridinyl amino acid derivatives as the anticancer agents with pristine (5, 5) single-walled carbon nanotube (SWCNT) and functionalized SWCNT (COOH-SWCNT) by the ONIOM2 (B3LYP/6-311G: UFF) and ONIOM2-PCM methods. The structural and electronic properties, binding energy, highest occupied molecular orbital and lowest unoccupied molecular orbital of the most stable configuration were also analyzed. Our results displayed that the interaction of the nanotubes with the derivatives of 9-acridinyl amino acid was relatively weak likewise the interaction and adsorption of the anticancer agents with SWCNT can be physical. The interaction of the anticancer agents on the f-SWCNT was more intense to the pristine SWCNT. In the aqueous solution, the solubility of the f-SWCNT as the carrier was increased.
Determinants of agricultural land rent and its development in Czechia

Zdenek, R. , Lososova, J. & Mrkvicka, T. (2019). Determinants of agricultural land rent and its development in Czechia. Bulgarian Journal of Agricultural Science, 25 (6), 1114–1121 The paper deals with the main factors infl uencing agricultural land rent and its development. We use our own sample survey data of agricultural farms complemented by the data from other sources. The sample contains 48 identical farms between 2011 – 2015 from the whole territory of the Czech Republic. The data were analysed with the mixed effect model. We investigated the infl uence of both agricultural and non-agricultural factors. Of the observed factors explaining the growth in land rent, the most important factor is time. Other signifi cant agricultural factors are land share in the LFA, the area of utilised agricultural land, production orientation on crop production, livestock density and the share of rented land. Population density is the only signifi cant non-agricultural factor.

Simulated study of plasmonic coupling in noble bimetallic alloy nanosphere arrays

The plasmonic coupling between the interacting noble metal nanoparticles plays an important role to influence the optical properties of arrays. In this work, we have extended the Mie theory results of our recent communication to include the effect of particle interactions between the alloy nanoparticles by varying interparticle distance and number of particles. The localized surface plasmon resonance (LSPR) peak position, full width at half maxima (FWHM) and scattering efficiency of one dimensional (1D) bimetallic alloy nanosphere (BANS) arrays of earlier optimized compositions i.e. Ag0.75Au0. 25, Au0.25Cu0. 75 and Ag0.50Cu0. 50 have been studied presently by using discrete dipole approximation (DDA) simulations. Studies have been made to optimize size of the nanosphere, number of spheres in the arrays, material and the interparticle distance. It has been found that both the scattering efficiency and FWHM (bandwidth) can be controlled in the large region of the electromagnetic (EM) spectrum by varying the nu.
Rietveld refinement of Debye–Scherrer synchrotron X‐ray data from Al2O3

The application of the Rietveld refinement technique to synchrotron X-ray data collected from a capillary sample of Al2O3 in Debye–Scherrer geometry is described. The data were obtained at the Cornell High Energy Synchrotron Source (CHESS) with an Si(111) double-crystal monochromator and a Ge(111) crystal analyzer. Fits to a number of well resolved individual peaks demonstrate that the peak shapes are very well described by the pseudo-Voigt function, which is a simple approximation to the convolution of Gaussian and Lorentzian functions. The variation of the Gaussian and Lorentzian half widths, ΓG and ΓL, with Bragg angle can be approximated quite closely by the functions V tan θ and X/cos θ which represent the contributions from instrumental resolution and particle-size broadening respectively. Rietveld refinement based on this model yields generally satisfactory results. The refined values of V and X are consistent with the expected vertical divergence (≃0.1 mrad) and the nominal particle size (≃ 0.3μm). In particular, the use of a capillary specimen virtually eliminates preferred orientation effects, which are highly significant in flat-plate samples of this material.
Applications and Datasets for Superpixel Techniques A Survey

—The use of superpixels instead of pixels can significantly improve the speed of the current pixel-based algorithms, and can even produce better results in many applications such as robotics, remote sensing, industrial inspection, and medical diagnosis. Two main tasks related to vision could beneﬁt from superpixels, named object class segmentation and medical image segmentation. In both cases, superpixels can increase performance signiﬁcantly and also reduce the computational cost. In addition to superpixel applications, various datasets were employed for the evaluation of the superpixel algorithms. This work aims to survey the recent applications and the most common datasets that can be used based on superpixel techniques.

The Case for Integrating Multi-Source Data for a Fairer and Holistic Judgement of Competence in Medical Education & Training

Being a doctor in the 21st Century requires a diverse range of skills, a broad base of knowledge and a suite of professional values and attitudes that enable clinical practice to be safe, effective and caring. Doctors, irrespective of their specialty, need to be knowledgeable and skilful not just in their area of expertise, but also need a range of generic skills and capabilities such as communication, leadership, academic scholarship and research, teaching, quality improvement, advocacy, digital literacy to name a few. These capabilities, all relevant to clinical practice, are assessed routinely in clinical settings. This rich information about trainees, available from their formative assessments, does not inform high-stakes judgements about progression. Instead, these judgements are usually made on the basis of summative examinations conducted in simulated settings. Unfortunately, these summative assessments have consistently delivered results with a large magnitude of differential between the outcomes of candidates, based on factors such as ethnicity, gender, other protected characteristics and also country of primary medical qualification. Formative assessment during training, however is individualised and tends not show this level of difference; leading to a situation where failure in summative examinations comes as a surprise to both trainees and to training programme directors. There is evidence that periodic assessment of trainees’ acquisition of core capabilities can help make balanced, informed judgements about readiness for progression. The move from a pass/fail categorisation to a yet/not yet categorisation when coupled with appropriate remedial measures can improve, both the validity, as well as fairness of assessments. The large magnitude of differential in outcomes of high-stakes assessments cannot be fixed by tweaking current assessment systems. Instead, there needs to be a recognition that high-level of capabilities consistently demonstrated in the workplace need to play a role in judgements about progression. Failure to do so is unfair, wasteful of public finances, and in breach of the trust places by the public, in training safe and competent clinicians.
Lowdin's Canonical Orthogonalization: Getting Round the Restriction of Linear Independence

Lowdin's canonical orthogonalization procedure can be useful in organizing large data sets, but it is applicable only to a set of linearly independent vectors. This places a serious constraint for there can be at most n linearly-independent vectors in an n-dimensional space. We propose two ways of getting round this restriction so that Lowdin's procedure can be used to find the vector along which all the given vectors—any number of them in a space of arbitrary dimensionality—project maximally. Under these conditions, this orthogonalization procedure is equivalent to the principal component analysis. © 2004 Wiley Periodicals, Inc. Int J Quantum Chem 99: 882- 888, 2004
QATAR’S EXPERIENCE WITH HEREDITARY BREAST AND OVARIAN CANCER AND HIGH RISK CLINIC: A RETROSPECTIVE STUDY 2013- 2016

Introduction: Approximately 5%-10% of breast cancer is hereditary and BRCA1 and BRCA2 genes are responsible for most of the cases. In the State of Qatar, the cancer genetics program was established at National Center of Cancer Care and Research on 2013 which is considered the first of its kind in the region dedicated exclusively to providing genetic counseling, risk assessment and management of high risk patients and their families. In this study, we aim to describe our experience with the hereditary cancer and high risk clinic from the period of March 2013 until December 2016.Methods: In this retrospective study, a total of 697 patients were evaluated at the high risk clinic between March 2013 to December 2016. High risk patients were either placed under surveillance or offered genetic testing for the BRCA genes. Results: A total of 697 patients were evaluated at the high risk clinic in which 347 patients were considered eligible for high risk screening. 167 patients pursued genetic testing and 64 patients (38%) had BRCA mutations with BRCA1 being the most common, while 72 patients (43%) were BRCA negative. A total of 31 patients (19%) had variants of unknown significance in the BRCA genes. Most of the BRCA positive patients 63% were affected with either breast and/or ovarian cancers and were within younger age group, while 38% were unaffected. 55% of those BRCA positive affected patients had triple negative breast cancer. The prevalence of BRCA mutations among Qatari breast cancer patients reaches up to 10% while it reaches approximately 3.5% among nonQatari breast cancer patients. Conclusion: Our program is an example of a well-established and multidisciplinary service targeted toward prevention and personalized medicine in high risk patients that goes in line with Qatar’s 2022 vision of achieving excellence in cancer care. From our unique experience, we show that BRCA mutations are prevalent among Qatari breast cancer patients reaching approximately 10% which can partially explain the young onset diagnosis of breast cancer in Qatar. With the higher awareness about our service and the recent establishment of BRCA testing at HMC, it is believed that the prevalence of BRCA is going to increase. In addition, with the introduction of multigene panel at our clinic, we believe that it will provide us [Bujassoum et. al., Vol.5 (Iss.10): October, 2017] ISSN2350-0530(O), ISSN2394-3629(P) DOI: 10.5281/zenodo.1040670 Http://www.granthaalayah. com ©International Journal of Research GRANTHAALAYAH [185] with new perspective on all hereditary cancers.

Contacts on n-type germanium using variably doped zinc oxide and highly doped indium tin oxide interfacial layers

The impact of varying interfacial layer (IL) doping on the performance of Ti/IL/n-Ge contacts is demonstrated using undoped ZnO, aluminum-doped ZnO (AZO), and O-vacancy-doped n+-ZnO ILs having similar conduction band offsets ΔEc with respect to Ti and Ge. Diode and transfer length method measurements show Fermi-level unpinning for all the ILs; however, the contact resistance and its dependence on the IL thickness decrease with increasing IL doping owing to the reduction in the tunneling resistance. The contact resistivity depends on the IL doping (NIL) as for N_{\text{AZO}} > N_{\text{ZnO}}$? >. Contacts using a highly doped, low ΔEc tin-doped In2O3 IL exhibit the lowest value, 1.4 × 10−7 Ω·cm2.
Corrosion Inhibition of Cu-Zn-Fe Alloy in Hydrochloric Acid Medium by Crude Ethanol Extracts from Roots-Leaves Synergy of Solanum melongena

The corrosion inhibition of Cu-Zn-Fe alloy in hydrochloric acid medium by crude ethanol extracts from roots-leaves synergy of Solanum melongena have been studied with chemical methods (mass loss and gasometric methods). At 3.0 grams per litre concentration of the roots-leaves synergy of Solanum melongena, it was observed that a 98.8 % inhibition efficiency was recorded as corrosion rate of alloy was decreasing with inhibitor increase. Temperature evaluation on the inhibitor showed 99.2 > 88.4 > 85.6 % as trial was conducted from 303-323 respectively, and in respect to increasing concentration, corrosion rate was found to be 1.718 > 0.013, 0.0192 and 0.247 at 303, 313 and 323 respectively. All these present a good result for the synergistic inhibitor and a proof of its efficiency in controlling the corrosion of Cu-Zn-Fe alloy in hydrochloric acid medium. Inhibition mechanism was deduced from the activation and thermodynamic parameters that govern the process. Adsorption of extract on the Cu-Zn-Fe alloy was found to obey the Langmuir adsorption isotherm. The phenomenon of physical adsorption is proposed from the obtained thermodynamic parameters.
