Resilience of athletes with physical disabilities: A cross-sectional study

El objetivo de este estudio fue evaluar la resiliencia de 208 atletas con discapacidades fisicas y examinar la Escala de Resiliencia de Wagnild e Young. Las puntuaciones medias de la resiliencia fueron similares para los hombres ( X = 132.4 ± 30.9) y mujeres ( X = 131.4 ± 35.7), considerado como resiliencia moderada. Se observo que los participantes con lesion de la medula espinal y mielomeningocele mostraron mejores resultados en resiliencia, mientras que aquellos con paralisis cerebral presentaran los peores y los amputados y con la polio tenian puntuaciones intermedias ( F = 3, p = .019). Los participantes en este estudio tenian una media de resiliencia ( X = 132.13 ± 32.25) significativamente menor que la reportada en otros estudios que evaluaban la poblacion general. El analisis factorial se mostro multidimensional, con siete factores responsables por 61.27% de la varianza total. Ademas, el instrumento mostro buena consistencia interna ( α = .88). La moderada resiliencia encontrada en este estudio indica que existe un potencial para desarrollo de la resiliencia en estos atletas
Generational and gender differences in response to traditional male and female personality characteristics

Tricia M. Cirineo Generational and Gender Differences in Response to Traditional Male and Female Personality Characteristics 1999 Dr. Dihoff School Psychology There are many stereotypes pertaining to what is a typical male and typical female characteristic. The purpose of this study was to determine the difference in attitudes towards these characteristics between two different generations. Many theorists feel that masculine and feminine characteristics are on opposite poles of a continuous spectrum, while others feel it is possible to possess both masculine and feminine characteristics, termed androgyny. The Bem Sex Role Inventory, the measure utilized in the present study, was developed to measure masculine and feminine characteristics, as well as the concept of androgyny (Bem, 1974). The sample in this study consisted of 90 participants. Each subject completed the BSRI. This is a 60 item self-report measure. Subjects indicated how well the personality characteristics described themselves. Findings were there was no significant differences found between generations in their responses to the BSRI. However, there was a significant difference between males and females in each generation. There was no interaction effect between generation and gender regarding responses to the BSRI. In conclusion, typical male and female characteristics were endorsed by the subjects of this study. Consistent with previous literature, significant differences were found between male and female responses to the BSRI.
Investigating English Teachers' Awareness of Pedagogical Competence and its Effect on Students' Language Learning

The study examined the impact of high school English teachers’ awareness of pedagogical competence on student learning. A psychometric measurement instrument of English language teachers' pedagogical competence (ELTPC) was first developed through factor analysis with 320 high school teachers in Guilan, Northern Iran. Based on the developed instrument, 36 teachers were divided into two groups of aware and unaware teachers of pedagogical competence (PC) according to Contrasting Groups Method of cut score. Then, 160 high school third graders received instruction from the aware and unaware teachers for 7 weeks. Finally, a survey regarding the teachers’ implementation of pedagogical competence in classrooms was conducted with 30 students. The findings from the experiment and survey supported the teachers in aware group. Although, based on the survey results, the aware teachers were reported to act better, they were not reported as highly practicing the pedagogical competence. The findings can be practically used by schools, education administration, and teacher educators.
Analyzing data independent acquisition mass spectrometry with noiseless ion-networks

Despite technical improvements in data-independent acquisition (DIA) mass spectrometry (MS) such as ion mobility separation (IMS) and scanning quadrupoles, there is still a trade-oﬀ between data integrity and chimericy. Here we present how to collapse multiple reproducible DIA runs from diﬀerent samples into a single noiseless ion-network that computationally eliminates chimericy. This natural DIA data format is ideally suited for untargeted fragment identiﬁcation and liberates hardware to prioritize data integrity towards an unprecedented quantitative accuracy. The last decade, liquid chromatography (LC)-MS techniques have been developed that replace the stochastic precursor selection of data-dependent acquisition (DDA) with predeﬁned window selection for fragmentation. Hence, these DIA techniques acquire a reproducible periodic signal for each individual fragment of all eluting analytes. An early example of DIA is MS e , wherein each low energy (LE) precursor scan is followed by a single high energy (HE) fragment scan. Hereby an optimal data integrity is obtained for all precursors and their fragments in the 0 to 2,000 mass-to-charge ratio ( m/z ) window [1]. Unfortunately, the simultaneous fragmentation of all precursors also generates the most chimeric data possible, i.e. independent fragments from multiple precursors cannot easily be related to each other or their original precursor anymore. While there are examples of software tools that create DDA-like pseudo-spectra per precursor by retrieving their fragments [2], such spectrum-centric representations are inherently unable to capture all intricacies of DIA. More commonly targeted multiple-reaction-monitoring (MRM)-like approaches are taken, colloquially called peptide-centric in the proteomics domain [3]. However, such targeted approaches rely on prior assumptions about sample content that cannot always be made
Floating matrix tablets of atenolol: Formulation and in vitro evaluation

The purpose of the study was to prolong the gastric residence time of atenolol by designing its floating tablets and to study the influence of different polymers on its release rate. Nine formulations of atenolol containing varying concentrations of polymers were designed by optimization. The floating matrix tablets of atenolol were prepared by direct compression method. The prepared tablets were evaluated for physicochemical parameters such as hardness, floating properties (floating lag time, floating time and matrix integrity), swelling studies and drug content. The physicochemical parameters of formulated tablets were found to be within normal range. A significant difference in drug release (P , 0.0001) and floating lag time (P , 0.005) at 0.5, one, four and eight hours were observed. The floating lag time of all the formulations was within the prescribed limit (,10 minutes). All the formulations showed good matrix integrity and retarded the release of drug for eight hours. The release pattern of atenolol was fitted to different models based on coefficient of correlation (r). All the formulations, except F2, F3 and F6 showed Korsemeyer-Peppas model as the best fit model. Formulation F2 and F3 showed first order model while F6 showed zero order model. Diffusion exponent (n) value was found in the range of 0.52-0.99 indicating diffusion as a release mechanism. The swelling studies of all the formulations showed that formulations containing Xanthan gum has higher swelling indices than HPMC K100M and HPMC K4M. It can be concluded that formulations with higher swelling indices retarded the release of drugs more than those with lower swelling indices.
Bombesin-functionalized superparamagnetic iron oxide nanoparticles for dual-modality MR/NIRFI in mouse models of breast cancer

Background The early and accurate detection afforded by imaging techniques significantly reduces mortality in cancer patients. However, it is still a great challenge to achieve satisfactory performance in tumor diagnosis using any single-modality imaging method. Magnetic resonance imaging (MRI) has excellent soft tissue contrast and high spatial resolution, but it suffers from low sensitivity. Fluorescence imaging has high sensitivity, but it is limited by penetration depth. Thus, the combination of the two modes could result in synergistic benefits. Here, we design and characterize a novel dual-modality MR/near-infrared fluorescence imaging (MR/NIRFI) nanomicelle and test its imaging properties in mouse models of breast cancer. Methods The nanomicelles were prepared by incorporating superparamagnetic iron oxide (SPIO) nanoparticles into 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[amino(polyethylene glycol)-5000] micelles to which an NIRF dye and a tumor-targeted peptide (N3-Lys-bombesin, Bom) were conjugated. The nanomicelles were characterized for particle size, zeta potential and morphology. The transverse relaxivity, targeting specificity and imaging ability of the nanomicelles for MR/NIRFI were also examined. Results The fabricated nanomicelles displayed a well-defined spherical morphology with a mean diameter of 145±56 nm and a high transverse relaxivity (493.9 mM−1·s−1, 3.0T). In MRI, the T2 signal reduction of tumors in the Bom-targeted group was 24.1±5.7% at 4 hrs postinjection, whereas only a 0.1±3.4% (P=0.003) decrease was observed in the nontargeted group. In NIRFI, the contrast increased gradually in the targeted group, and the tumor/muscle ratio increased from 3.7±0.3 at 1 hr to 4.7±0.1 at 2 hrs and to 6.4±0.2 at 4 hrs. No significant changes were observed in the nontargeted group at any time points. Conclusion Considering all our results, we conclude that these novel MR/NIRFI dual-modality nanomicelles could be promising contrast agents for cancer diagnosis.
Histological Effect of Bacillus thuringiensis Isolate against Pink Bollworm Larval Midgut, Pectinophora gossypiella (Saund.)

Experiments were conducted to assess the impact of Bacillus thuringiensis isolate against the midgut of larvae for pink bollworm (PBW) Pectinophora gossypiella (Saund.). The data illustrated indicated that the LC50 value of the tested potent isolate was 3.77 CFU/ml; the confidence limits at (95%) were 2.934. 91CFU/ml. In addition, LC90 value also determined and it obtained 44.23 CFU/ml. and its confidence limits at (95%) were 23.18149. 70 CFU/ml. The effects of the bacterial isolate on the midgut of 4 larval instar of the pink bollworm, treated with LC50CFU/ml showed several histological changes some epithelial cells were disintegrated, vacuolated and their cell boundaries were destructed and separated from the basement membrane. The peritrophic membrane was also destructed and detached from the epithelial cells. In general, epithelium layer in untreated specimen was thicker than that in bacterial treated one. The mode and site of action of the active isolates on PBW larvae have been investigated with Transmission Electron Microscope. The Columnar epithelial cells of the midgut showed the muscle layer surrounding the basement membrane lost its normal appearance and degenerated. An increase of deeply infoldings of the basement membrane occurred and the mitochondria of the basal regions were transformed into a condensed form. Separation in columnar and goplet cells occurred and cleared scatting into the gut luman. Microvilli were disrupted showing non-altered appearance. Strong alterations of cytoplasmic structure and organelles occurred. Also, the cytoplasm was distinguished by numerous vacuoles and destroyed brush border. Fragmented chromatin inside the nucleus that has a terminal position destroyed the nucleus sheath.
Does corporate diversification create value in emerging markets? New evidence from Chile

Using a sample of 85 Chilean firms listed in the Santiago Stock Exchange from 2005 to 2013, we analyze the impact of corporate diversification on firm value. We consider voting rights of the main shareholder and institutional investors’ influence on firm value. We report firm-value destruction for diversified firms. Regarding ownership concentration, we report a negative relation between the largest shareholder ownership and firm value. Separation between voting rights and cash flows rights of this shareholder is negatively related to firm value. While Pension Fund Administrators (AFP) mitigate firm value destruction in diversified firms, other institutional investors do not play an active role in controlling value destruction. Finally, if the largest owner is a family, we report firm-value creation in diversified firms. Copyright © 2016 ASAC. Published by John Wiley & Sons, Ltd.
Phytosociology of Native Species in the Understory of a Corymbia citriodora Stand in Espírito Santo State, Brazil

This study is based on the hypothesis that unmanaged plantations of commercial species do not prevent understory colonization by native species. The research aimed to describe the floristic composition and structure of native arboreal species in the understory of a Corymbia citriodora stand. To this end, 112 plots (10 × 10 m; 1.12 ha) were installed. Six hundred native tree individuals distributed in 54 species, 44 genera, and 20 families were recorded. The regeneration diversity and evenness indices were 3.23 and 0.81, respectively. Native regeneration of C. citriodora understory shows features typical of semideciduous seasonal forests and seems to be at the early stage of regeneration. Results suggest that C. citriodora stands do not prevent understory colonization by native species.
An ultra-broad-band reflection-type phase-shifter MMIC with series and parallel LC circuits

An ultra-broad-band reflection-type phase shifter is proposed. Theoretically, the proposed phase shifter has frequency-independent characteristics in the case of 180/spl deg/ phase shift. The phase shifter is composed of a 3-dB hybrid coupler and a pair of novel reflective terminating circuits. The reflective terminating circuit switches two states of series and parallel LC circuits. Using an ideal circuit model without parasitic circuit elements, we have derived the determining condition of frequency independence of circuit elements. Extending the concept, we can also obtain a broad-band phase shifter for other phase difference as well. In this case, for a given phase difference and an operating frequency, we also derive a condition to obtain minimum variation of phase difference around the operating frequency. This enables the broad-band characteristics for arbitrary phase difference. The fabricated 180/spl deg/ reflective terminating circuit monolithic microwave integrated circuit (MMIC) has achieved a phase difference of 183/spl deg/ /spl plusmn/ 3 over 0.5-30 GHz. The 180/spl deg/ phase-shifter MMIC has demonstrated a phase shift of 187/spl deg/ /spl plusmn/ 7/spl deg/ over 0.5-20 GHz. The 90/spl deg/ reflective terminating circuit MMIC has performed a phase difference of 93/spl deg/ /spl plusmn/ 7/spl deg/ over 4-12 GHz.
Decreased oxygenation demand following hypolimnetic oxygenation

Abstract Gantzer PA, Preece EP, Nine B, Morris J. 2019. Decreased oxygenation demand following hypolimnetic oxygenation. Lake Reserv Manage. 35:292–307. We analyzed long-term oxygenation dynamics in 3 waterbodies: Spring Hollow Reservoir (SHR) and Carvins Cove Reservoir (CCR), which are water supply reservoirs, and North Twin Lake (NTL), a natural lake. Bubble plume line diffuser hypolimnetic oxygenation system (HOS) operation was for 13, 10, and 7 yr for SHR, CCR, and NTL, respectively. Water column profiles were measured in all 3 waterbodies. Additionally, remotely deployed sensors were used to monitor dissolved oxygen (DO) in NTL year-round, specifically to capture winter conditions during ice cover. Hypolimnetic oxygen demand (HOD) was observed to decrease after several years of HOS operation in all 3 waterbodies. Annual HOD decreased more for HOS operated year-round compared to recovery-based operation where HOS was started after DO decreased below 5.0 mg/L. Additionally, HOD throughout the summer stratified period was lower following maintenance of higher DO during spring prior to onset of stratification. An analogous result was observed during winter ice cover relative to DO conditions following fall turnover. Prior work showed increased HOD during HOS operation compared to pre-HOS. The increased HOD during HOS operation was termed diffuser-induced oxygen demand and implied the HOS was inducing oxygen demand. However, the current work shows HOS operation is not actually inducing oxygen demand; rather, it is addressing the existing oxygen demand already in the sediments. Our data suggest that a HOS is an effective tool to maintain hypolimnion DO in stratified lakes and reservoirs. When operated year-round or before DO decreases, HOS can decrease HOD and reduce overall long-term operational costs.

Los trabajos de investigacion sobre la hipotesis de la Paridad del Poder de Compra (PPP) han arrojado resultados mixtos; ademas, la mayoria no considera los cambios estructurales. El objetivo del trabajo es contrastar la hipotesis PPP para la economia mexicana tomando en cuenta los cambios estructurales de la relacion bajo doce diferentes definiciones del tipo de cambio, diferentes anos base y diferentes ponderaciones de comercio. Dependiendo de las definiciones del tipo de cambio real, algunos resultados confirman la hipotesis PPP como una relacion de largo plazo para el peso mexicano, mientras los resultados de otras definiciones no la confirman.
FROM SOURCE LOCALIZATION TO BLIND SOURCE SEPARATION: AN INTUITIVE ROUTE TO CONVOLUTIVE BLIND SOURCE SEPARATION

Most algorithms for blind source separation (BSS) of convolutive speech mixtures are derived in a deductive way from abstract statistical principles and exploit a combination of three signal properties, i.e. nongaussianity, nonwhiteness and nonstationarity. In this paper we show how a separation system can be build the opposite, inductive, way using basic speech processing building blocks. The main block and starting point of our derivation is a simple generalized cross correlation based localization system with two microphones. The capability of source separation (2 signals and 2 sensors) is added by duplicating the localization structure and adding an inhibition mechanism which suppresses already localized sounds. Finally, experimental results with artificially mixed speech signals are presented.
Effect of Preceding Winter Crops and Herbicidal Combinations on Weeds, Yield and Econemic Feasability of Broadcast-Seeded Rice Productivity.

Nowadays, in Egypt there is a big shift towards increasing the cultivated area with broadcast-seeded rice which needs to overcome the heavy out weeds infestation in this case. Thus, four field experiments were conducted at the Experimental Farm of El-Serw Agri. Res. Station, Damietta Governorate in 2014 and 2015 summer seasons, to investigate effect of clover and wheat as two preceding winter crops before sowing the rice as broadcast-seeded rice and six weed control treatments [Saturn at 2.0 L/ faddan + Basagran at 1.5 L/ faddan, Ronstar at 0.75 L/ faddan + Enpul at 20 g/faddan, Rainbow at 0.4 L/ faddan + Enpul at 20 g/ faddan, Rainbow at 0.4 L/ faddan + Basagran at 1.5 L/ faddan combinations, hand weeding twice and untreated check] in each experiment on weeds, rice grain yield and its components with economic evaluation. The main findings indicated that sowing the rice as broadcasted after clover; and weed control treatments irrespective of the preceding winter crops decreased significantly the dry weight of both dicot and monocot weeds and markedly increased rice grain yield (ton/faddan) and its components i.e., plant height, number of tillers/m, number of panicles/m, number of filled grain/panicle and weight of grain/panicle, that is true in both seasons. In first season the interaction between clover as a preceding winter crop and herbicides combinations i.e. Rainbow 2.5% OD (penoxsulam) at 0.4 L/ faddan followed by Enpul 75% WG (halosulfuron-methyl) at 20 g/faddan; Rainbow 2.5% OD at 0.4 L/faddan followed by Basagran 48% AS (bentazon) at 1.5 L/ faddan; Ronstar 25% EC (oxadiazon) followed by Enpul 75% WG at 20 g/faddan and Saturn 50% EC (thiobencarb) at 2.0 L/faddan followed by Basagran 48% AS at 1.5 L/faddan reduced the total weeds by 91.7, 91.3, 88.5 and 86.3%, respectively, at 70 DAS, and accompanied with significant increases on rice grain yield by 145.3, 154.0, 122.0 and 148.0% than untreated check, respectively. Whilst, hand weeding twice was less effective on reducing the total weeds by 56.5 and 53.4% at the respective assessments and reflect that to increase rice grain yield in both seasons. The highest net income/faddan were obtained by the previous herbicidal combinations in trials preceded with clover than wheat during the two seasons. This study throw lights about suitable and satisfactory herbicidal combinations to overcome the heavy weeds infestation problem in broadcast-seeded rice. These results indicated that under heavy infestation with weeds in broadcastseeded rice, it is possible to grow broadcast-seeded rice after clover with using one herbicides combinations,( Rainbow at 0.4L/fed + Enpul at 20 g/fed, Rainbow at 0.4L/fed + Basagran at 1.5 L/fed, Ronstar at 0.75 L/fed + Enpul at 20g/fed; and Saturn at 2.0 L/fed + Basagran at 1.5 L/fed) which, gave the highest redution weeds, increase broadcastseeded rice yield and the highest economic values in both seasons.
Use of genetic data for conservation management: the case of the Arabian oryx

In this study we investigate some applications of genetic markers in animal conservation, using the Arabian oryx (Oryx leucoryx) as an example. Out of 66 sets of microsatellite primers from other ruminants, 58% were found to amplify microsatellites in Arabian oryx. Polymorphism (50% of loci amplified) and allelic diversity (mean 2.1 alleles/locus amplified) were within the range found in other ruminants. Arabian oryx (n= 343) representing most of the major groups world‐wide were typed at six loci. Low but significant population differentiation was found between most oryx groups, suggesting that management of Arabian oryx has led to substantial genetic mixing between populations. Forty percent of the alleles in one additional Arabian oryx sample from the pre‐extinction population in Oman were not found in any contemporary Arabian oryx, and two out of four contemporary populations were deficient in rare alleles, suggesting that the species has lost some neutral genetic variation. The microsatellite loci were sufficiently polymorphic for identification of an Arabian oryx sample in a forensic context, but were not sufficiently polymorphic for large‐scale parentage inference. We suggest that it is important to evaluate whether genetic markers are likely to have sufficient power to answer particular conservation questions prior to committing conservation resources to genetic typing.
Neutrophilic Leukocytosis in Infectious Mononucleosis: A Case Series Report

Introduction: Infectious mononucleosis is a relatively common childhood disease caused by the epstein-barr virus (EBV). Typical cases are seen in young children and are mostly clinically mild or asymptomatic. In this disease, leukocytosis with predominance of lymphocytes is found. Classical clinical symptoms associated with atypical lymphocytosis in the peripheral blood smear helps in diagnosis. Case Presentation: The patients were proven cases of infectious mononucleosis disease and unlike the typical cases of this infection; they showed high ESR (erythrocyte sedimentation rate), CRP (C-reactive protein), and neutrophilic leukocytosis, instead of lymphocytosis. All of them were discharged in good general condition after receiving corticosteroids. Conclusions: According to our findings, EBV infection cannot be ruled out in exudative pharyngitis, despite having neutrophilic leukocytosis, high levels of ESR and CRP. Therefore, EBV diagnostic tests should be conducted in these patients.
