Pulsar Radio Emission Mechanism: Radio Nanoshots as a Low-frequency Afterglow of Relativistic Magnetic Reconnection
Authors: Philippov Alexander , Uzdensky Dmitri A. , Spitkovsky Anatoly , Cerutti Benoît
Published: April 2019

In this Letter we propose that coherent radio emission of the Crab pulsar, other young energetic pulsars, and millisecond pulsars is produced in the magnetospheric current sheet beyond the light cylinder. We carry out global and local 2D kinetic plasma simulations of reconnection to illustrate the coherent emission mechanism. Reconnection in the current sheet beyond the light cylinder proceeds in the very efficient plasmoid-dominated regime, where the current layer gets fragmented into a dynamic chain of plasmoids that undergo successive coalescence. Mergers of sufficiently large plasmoids produce secondary perpendicular current sheets, which are also plasmoid unstable. Collisions of plasmoids with each other and with the upstream magnetic field eject fast magnetosonic waves, which propagate upstream across the background field and successfully escape from the plasma as electromagnetic waves that fall in the radio band. This model successfully explains many important features of the observed radio emission from the Crab and other pulsars with high magnetic field at the light cylinder: phase coincidence with the high-energy emission, nanosecond duration (nanoshots), and extreme instantaneous brightness of individual pulses.

Authors: Sastre-Riba Sylvia , Fonseca-Pedrero Eduardo , Ortuño-Sierra Javier
Published: April 2019

The aim of the study was to understand the components associated with the types of perfectionism described as adaptive/healthy, maladaptive/unhealthy or non-perfectionism, which could offer positive or negative aspects to improve excellence and well-being, exploring the number and content of the latent perfectionism structure as a multidimensional construct in a sample of High Intellectual Abilities (HIA) students. Links with Positive and Negative perfectionism were also compared across perfectionism latent profiles. A total of n=137 HIA students, mean age 13.77 years (SD=1.99), participated in a survey. The Almost Perfect Scale Revised (APS-R) and Positive and Negative Perfectionism Scale-12 (PNPS-12) were used. Results obtained showed three latent classes (LC): ‘Unhealthy’ (LC1), ‘Healthy’ (LC2) and ‘No perfectionism’ (LC3). LC1 showed high scores on Discrepancy subscales but low in Order and High Standards. LC2 displayed higher scores on High Standards and Order. LC3 displayed low scores across all perfectionism facets. Statistically significant differences were found across latent profiles in almost all perfectionism features. Different patterns of associations with Positive and Negative perfectionism were obtained across latent profiles. These findings address the latent structure of perfectionisms in HIA students and allow us to delimit, analyze, and understand the tentative latent profiles within the HIA arena.

El objetivo de este estudio fue comprender los componentes asociados a distintos tipos de perfeccionismo descrito como: adaptativo/sano, mal adaptativo/insano o no perfeccionismo que pueden tener efectos positivos o negativos para el logro de la excelencia. Se exploró el número y contenido de las estructuras latentes del perfeccionismo como constructo multidimensional en una muestra de n=137 estudiantes con Altas Capacidades Intelectuales (ACI) con una media de edad de 13,77 años (DT=1,99). La conexión con el perfeccionismo positivo y negativo se analizó sobre la base de los diferentes perfiles de perfeccionismo. Se utilizaron las escalas «Almost Perfect Scale Revised» (APS-R) y la «Positive and Negative Perfectionism Scale-12». Los resultados mostraron tres clases latentes de perfeccionismo: «No Sano» (CL1), «Sano» (CL2) y «No Perfeccionista» (CL3). La CL1 mostró puntuaciones más altas en las subescalas de Discrepancia y bajas en Orden y Altos Estándares. La CL2 reveló puntuaciones altas en Altos Estándares y Orden. La CL3 mostró bajas puntuaciones en todos los dominios de perfeccionismo. Las diferencias fueron estadísticamente significativas entre las clases latentes en los dominios del perfeccionismo. Asimismo, se encontraron diferentes patrones de asociaciones de las clases latentes con el perfeccionismo Positivo y Negativo. Los resultados encontrados permiten atender a las estructuras latentes de perfeccionismo en estudiantes con ACI, que posibilitan delimitar, analizar y entender posibles perfiles latentes.

Community-Based Older Adults' Acceptance of and Willingness Toward Waist Circumference Measurement
Authors: Gaynor Beatrice , Wright Regina , Shin Ju Young
Published: April 2019

Older adults have higher rates of central obesity and greater risk for central obesity–related diseases compared to younger adults. Waist circumference measurement is a reliable indicator of preventable, central obesity–related disease risk. Despite its value, it is rarely measured in primary care settings due to providers' perceived patient discomfort with waist measurement. The current study examined community-based older adults' (
N
= 99) experience with, acceptance of, and willingness toward waist measurement. Ninety-two percent of participants reported never having waist measurement in primary care settings. Despite lack of waist measurement experience, 62.6% reported feeling “very” comfortable and 82.8% were “very willing” to have waist measurement. High acceptance of and willingness toward waist measurement in the absence of experience supports acceptability of waist measurement among older adults. Thus, providers are encouraged to use waist measurement to screen older adults for central obesity and associated disease risk. [

Heightening Person-Centered Care Processes in the Delivery of Nursing Restorative Care
Authors: Abrahamson Kathleen , Mueller Christine , Duan Yinfei , Cooke Valerie
Published: April 2019

The objective of the current study was to investigate the perspectives of nursing home (NH) providers regarding the requirements to achieve reimbursement for nursing restorative care (NRC) services and propose recommendations to state agencies to assist NH providers to conduct NRC programs that are person-centered and able to achieve full reimbursement. Methods included a survey of NH providers in one state and a stakeholder focus group to discuss survey findings and develop recommendations. Key findings are that NH providers perceive value to residents from the provision of NRC; providers do not associate these benefits with the stringent reimbursement requirements; and NHs often provide NRC that is individualized, based on resident goals and activity tolerance, as well as realistic given competing demands on staff, even when doing so means giving up reimbursement for NRC services. Recommendations include basing reimbursement for NRC on outcomes rather than the process; reconsideration of the frequency and intensity requirements for NRC components; and increased availability of NRC training/education and resources for providers and case-mix reviewers.

Improving Education and Communication in an Assisted Living Facility to Reduce Avoidable Emergency Department Transfers: A Quality Improvement Project
Authors: Abate Betelehem , VanGraafeiland Brigit
Published: April 2019

The purpose of the current project was to determine the effectiveness of training and communication tools used as intervention strategies to reduce unnecessary emergency department transfers of assisted living facility (ALF) residents. Two communication protocols (SBAR and STOP and WATCH) were introduced to standardize clinical communication among licensed practical nurses (LPNs) and clinical providers. Twenty-nine LPNs working in an ALF with 172 units were recruited. LPNs participated in an intervention intended to improve knowledge on geriatric syndromes. Pre- and postintervention testing revealed improved LPN knowledge of geriatric syndromes. A satisfaction survey indicated positive LPN acceptance of the standardized communication tools. Through daily auditing of charts, adherence with use of the SBAR tool was 87%. This evidence-based, educational intervention project aimed to improve nursing staff geriatric knowledge, monitor nurse adherence to using the SBAR and STOP and WATCH tools, and assess overall satisfaction with use of SBAR.

Nutritional composition and antioxidant activity of different walnut varieties (Juglans regia L.) from Nerpio (Spain) in comparison to commercial varieties
Authors: Viera-Alcaide I. , Hamdi A. , Jiménez-Araujo A. , Rodríguez-Arcos R. , Espejo-Calvo J. A. , Guillén-Bejarano R.
Published: April 2019

In the Nerpio region (Albacete, Spain), endogenous walnut cultivars have been grown since ancient times. None of them has been chemically characterized to valorize them in comparison to commercial varieties. In this work, 47 native (N) and 7 foreign (F) walnut cultivars grown in Nerpio, and 13 commercial (C) samples were studied during three seasons. The average yield, moisture, and protein and oil contents were slightly lower in the N samples than in C. The composition of fatty acid suggested that the N walnuts could be more stable against oxidation due to their higher amount of MUFA and lower amount of PUFA. The biological protein value for the samples was similar but the antioxidant capacity marked important differences among them: N cultivars reached the highest scores, with intermediate F values. Local walnut varieties from Nerpio should be valorized on the basis of their potentially enhanced health benefits, although further studies must be developed on their phytochemicals.

The Rise of Robotics Data for Real-Time Management Based on New NoSQL Solution
Authors: Gueidi Afef , Gharsellaoui Hamza , Ben Ahmed Samir
Published: April 2019

In the face of the rapid growth of data, the authors note the birth of new computer systems leading the management of databases. To ensure reliable handling of data which is bulky and heterogeneous, new systems of basic management data are differentiated from traditional ones by their linear scalability to store and manage data in parallel. Those systems are called NoSQL DB. Robotics database management systems are increasing. These systems ensure good storage of data and with big data analytics, a new approach demands new structures and methods for collecting, recording, and analyzing enterprise data. This journal article deals with the NoSQL DB which are the secret of the continual progression data that new data management solutions have emerged. The implementation of NoSQL for Robotics wrestles all data they acquire into a usable form because with the ordinary type of Robotics, people are facing big limits to find the best decision in real-time. The authors' proposed approach was based on a combination of some experimental studies in the same area.
Cutting Edge: ATM Influences Germinal Center Integrity

Published: April 2019

The DNA damage response protein ATM has long been known to influence class switch recombination in ex vivo–cultured B cells. However, an assessment of B cell–intrinsic requirement of ATM in humoral responses in vivo was confounded by the fact that its germline deletion affects T cell function, and B:T cell interactions are critical for in vivo immune responses. In this study, we demonstrate that B cell–specific deletion of ATM in mice leads to reduction in germinal center (GC) frequency and size in response to immunization. We find that loss of ATM induces apoptosis of GC B cells, likely due to unresolved DNA lesions in cells attempting to undergo class-switch recombination. Accordingly, suboptimal GC responses in ATM-deficient animals are characterized by decreased titers of class-switched Abs and decreased rates of somatic hypermutation. These results unmask the critical B cell–intrinsic role of ATM in maintaining an optimal GC response following immunization.
Diffuse low-grade glioma – Changing concepts in diagnosis and management: A review
Authors: Jooma Rashid , Waqas Muhammad , Khan Inamullah
Published: April 2019

Though diffuse low-grade gliomas (dLGGs) represent only 15% of gliomas, they have been receiving increasing attention in the past decade. Significant advances in knowledge of the natural history and clinical diversity have been documented, and an improved pathological classification of gliomas that integrates histological features with molecular markers has been issued by the WHO. Advances in the radiological assessment of dLGG, particularly new magnetic resonance imaging scanning sequences, allow improved diagnostic and prognostic information. The management paradigms are evolving from “wait and watch” of the past to more active interventional therapy to obviate the risk of malignant transformation. New surgical technologies allow more aggressive surgical resections with a reduction of morbidity. Many reports suggest the association of gross total resection with longer overall survival and progression-free survival in addition to better seizure control. The literature also shows the use of chemotherapeutics and radiation therapy as important adjuncts to surgery. The goals of management have has been increasing survival with increasing stress on quality of life. Our review highlights the recent advances in the molecular diagnosis and management of dLGG with trends toward multidisciplinary and multimodality management of dLGG with an aim to surgically resect the primary disease, followed by chemoradiation in cases of progressive or recurrent disease.
Intraorbital solitary fibrous tumor requiring preoperative embolization of feeding artery

Published: April 2019

Solitary fibrous tumors (SFTs) are derived from mesenchymal cells and commonly develop in thoracoabdominal organs; however, their occurrence in orbit is rare. The first-choice treatment is to surgically remove as much of the SFT as possible; however, if total removal is not achieved, the recurrence rate is high, resulting in poor prognosis. A 42-year-old man presented with painless right-sided proptosis and diplopia 4 years ago. Orbital computed tomography revealed a right extraconal mass medial to the optic nerve, measuring 25 mm. Magnetic resonance imaging demonstrated iso-signal intensity on T1- and T2-weighted imaging, including flow-void signals. During biopsy of the intraorbital mass, which was performed by ophthalmologists 3 years earlier, difficulty with hemostasis occurred due to massive hemorrhage from the mass. The mass grew to reach a maximal diameter of 33 mm, resulting in referral to the authors' department. Diagnostic cerebral angiography revealed a hypervascular orbital tumor with multiple feeding arteries. To control intraoperative bleeding, the patient underwent preoperative endovascular embolization. Subsequently, the tumor was completely removed using a combination of microsurgical craniotomy and endoscopic endonasal approach, without the occurrence of massive intraoperative hemorrhage from the tumor. Postoperatively, his clinical course was uneventful except for the remaining preoperative diplopia. The tumor was diagnosed histologically as SFT and has not recurred for 8 months since surgery. Preoperative intravascular embolization of branches of the ophthalmic artery can be performed safely, resulting in excellent control of intraoperative bleeding and facilitating complete removal of SFT without additional complications.
Effect of preoperative modic change in the outcome of patients with low back pain following posterior spinal fusion or laminectomy
Authors: Shahmohammadi Mohammad , Behrouzian Sima
Published: April 2019

Background: Modic changes (MC), visible on magnetic resonance imaging (MRI) are associated with chronic low back pain (LBP). It is reported that different MC types could affect the surgical outcome in patients with LBP. Objective: In this study, we evaluated the effect of MC Type I and II on patients with LBP and degenerative disc disease following posterior spinal fusion (PSF) or laminectomy. Materials and Methods: We evaluated the outcome of 162 patients with LBP and MC Type I and II who underwent laminectomy (n = 72) or PSF (n = 90). Preoperative MRI was used to define MC types. Visual analog scale (VAS) was used to evaluate the pain intensity before and 3 months after surgery. Results: Patients had MC Type I in 46.3% and Type II in 53.7%. Pain VAS significantly decreased following surgery (7.93 ± 1.27–5.98 ± 1.57, P < 0.001). There was no difference between MC Type I and II in pain VAS before (P = 0.51) and after treatment (P = 0.51). Among MC Type I, PSF compared to laminectomy had significantly more improvement in pain VAS (P = 0.01), but the changes in modic Type II were similar between groups (P = 0.89). Conclusion: Surgical treatment in patients with LBP with MC accompanies with significant improvement in pain. PSF seems better treatment in patients with MC Type I.

Authors: Silva Jonh Billy , Gaio Denilton Carlos , Curado Leone Francisco Amorim , Nogueira José De Souza , Valle Júnior Luiz Claudio Galvão , Rodrigues Thiago Rangel
Published: April 2019

This study analyzed the performance of the Brunt (1932), Swinbank, (1963), Idso and Jackson (1969), Brutsaert (1975), Idso (1981), and Bignami et al. (1995) methods to estimate atmospheric emissivity under grass-dominated savannas (known as campo sujo Cerrado), in the region of Baixada Cuiabana. The estimates were compared with data obtained by energy balance equation in two seasons, dry season (May to August), and wet season (September to December) of 2009. The Swinbank and Idso and Jackson methods, that consider only air temperature, show better performances for the wet season. However, methods that consider water vapor pressure and air temperature (Brunt, Brutsaert, Bignami and Idso) show good performances for the dry season. The Idso and Brutsaert methods show the highest index of agreement and are recommended to estimate atmospheric emissivity for the region.
Tidal impacts on primary production in the North Sea
Authors: Zhao Changjin , Daewel Ute , Schrum Corinna
Published: April 2019

Abstract. This study highlights the importance of tides in controlling the spatial and
temporal distributions of phytoplankton and other factors related to growth,
such as nutrients and light availability. To quantify the responses of net
primary production (NPP) to tidal forcing, we conducted scenario model
simulations considering M2 and S2 tidal constituents using the
physical–biogeochemical coupled model ECOSMO (ECOSystem MOdel). The results were
analyzed with respect to a reference simulation without tidal forcing, with
particular focus on the spatial scale of the tidally induced changes. Tidal
forcing regulates the mixing–stratification processes in shelf seas such as
the North Sea and hence also influences ecosystem dynamics. In principle, the
results suggest three different response types with respect to primary
production: (i) in southern shallow areas with strong tidal energy
dissipation, tidal mixing dilutes phytoplankton concentrations in the upper
water layers and thereby decreases NPP. Additionally, tides increase
turbidity in near-coastal shallow areas, which has the potential to further
hamper NPP. (ii) In the frontal region of the southern North Sea, which is a
transition zone between stratified and mixed areas, tidal mixing infuses
nutrients into the surface mixed layer and resolves summer nutrient
depletion, thus sustaining the NPP during the summer season after spring
bloom nutrient depletion. (iii) In the northern North Sea, the NPP response
to tidal forcing is limited. Additionally, our simulations indicate that
spring bloom phenology is impacted by tidal forcing, leading to a later onset
of the spring bloom in large parts of the North Sea and to generally higher
spring bloom peak phytoplankton biomasses. By testing the related changes in
stratification, light conditions and grazing pressure, we found that all
three factors potentially contribute to the change in spring bloom phenology
with clear local differences. Finally, we also analyzed the impact of the
spring–neap tidal cycle on NPP. The annual mean impact of spring–neap tidal
forcing on NPP is limited. However, locally, we found substantial differences
in NPP either in phase or anti-phase with the spring–neap tidal cycle. These
differences could be attributed to locally different dominant factors such as
light or nutrient availability during spring tides. In general, we conclude
that in shallow shelf seas such as the North Sea, intensified vertical mixing
induced by tidal forcing could either promote NPP by counteracting nutrient
depletion or hinder NPP by deteriorating the light environment because of the
resuspension and mixing of suspended matter into the euphotic zone.
Where should we draw the lines between dinocyst “species”? Morphological continua in Black Sea dinocysts
Authors: Hoyle Thomas M. , Sala-Pérez Manuel , Sangiorgi Francesca
Published: April 2019

Abstract. The morphology of dinoflagellate cysts (dinocysts) is related not only to the
genetics of the motile dinoflagellate from which it derives, but is also
dependent on a range of environmental factors including salinity, temperature
and nutrient status. Although this knowledge improves our understanding of
the drivers behind dinocyst morphological variations, it makes the taxonomy
governing their description somewhat complex. In basins such as the Black
Sea, where environmental change can be extreme and occurs on relatively short
(millennial) timescales, taxonomy becomes particularly challenging.
Morphological continua can be observed between described forms, displaying a
large range of intermediate phenotypes that do not necessarily correspond to
any genetic difference. As these morphological nuances may preserve
information about palaeoenvironments, it is important to find a systematic
method of characterising morphotypes. Here, we show a dinocyst matrix within
which dinocysts are described according to their similarity to (or difference
from) described forms based on key descriptive parameters. In the example set
out here, cyst shape and degree of process and/or ectophragm
development are taken as two key parameters in Pyxidinopsis psilata and Spiniferites cruciformis, and can allow the description of
intermediate forms even though the definitions do not overlap. We review some frequently occurring morphotypes and propose that using
matrices to show the gradual variation between endmember forms is the most
pragmatic approach until cyst–theca studies and genetic sequencing can be
used to demonstrate relationships between genotypes and morphotypes. As prior
studies propose salinity to be a primary driver of intraspecific variability,
the endmembers presented may represent salinity extremes within an overall
brackish environment. Although we cannot assign each morphotype to a value or
a range of an environmental parameter (e.g. salinity) as the different
morphotypes can occur in the same sample, using this matrix allows
preservation of information about morphological variability without creating
taxonomic categories that are likely to require alteration if genetic
evidence becomes available.
Buckling of elastically restrained nonlocal carbon nanotubes under concentrated and uniformly distributed axial loads
Authors: Robinson Mouafo Teifouet Armand , Adali Sarp
Published: April 2019

Abstract. Buckling of elastically restrained carbon nanotubes is studied subject to a combination of uniformly distributed and concentrated compressive loads. Governing equations are based on the nonlocal model of carbon nanotubes. Weak formulation of the problem is formulated and the Rayleigh quotients are obtained for distributed and concentrated axial loads. Numerical solutions are obtained by Rayleigh–Ritz method using orthogonal Chebyshev polynomials. The method of solution is verified by checking against results available in the literature. The effect of the elastic restraints on the buckling load is studied by counter plots in term of small-scale parameter and the spring constants.

Published: April 2019

The aim of this work is to identify the spectrum, frequency and antimicrobial resistance of bacterial pathogens occurring in sheep dairy herds in Slovakia. Of a total of 310 samples of sheep's milk coming from three breeds during two seasons (2017 and 2018), at least one potential pathogen was isolated from 102 samples (32.9%). A total of 131 microbial isolates were isolated. The most represented species were coagulase negative staphylococci CoNS (75.6%), followed by Streptococcus agalactiae (10.7%), Staphylococcus aureus (6.9%), Streptococcus dysgalactiae (4.6%), Escherichia coli (1.5%), Enterococcus faecium (1.5%), and others (Streptococcus uberis, Streptococcus parauberis, Candida sp., Klebsiella sp., moulds) below 1%. A total of 99 isolates of CoNS were tested for antimicrobial resistance. Of these, 63.6% were resistant to at least one antibiotic. A total of 24.2% of the tested isolates were resistant to 3 groups of antimicrobials simultaneously (multi-drug resistance). The highest resistance was observed to lincomycin (57.6%) and neomycin (36.4%), the lowest to sulfamethoxazolum+trimethoprim (0%) and enrofloxacin (3.0%). Based on the results of this work, it is possible to assume a similar spectrum of pathogens and their antimicrobial resistance described in the literature also within the Slovak sheep  farms focused on milk production.

Authors: Angelovičová Mária , Klimentová Michaela , Angelovič Marek
Published: April 2019

The purpose of this study was to investigate of the broiler chicken thigh muscle fat profile after feeding a commercial supplement based on eugenol, nerolidol and piperine applied in feeding mixtures. Broiler chickens Ross 308 were reared in a pen equipped with a straw deep litter and placed into 2 groups. One group was designated as control and the second as experimental. Difference between control and experimental groups was in using of feed supplement in experimental feeding mixtures. Experimental supplement is a commercial powder product which was used in an amount of 10 g per 100 kg of feeding mixtures. Chickens of body weight of 1800.0 g were selected from each group, human killed and technologically processed to carcass. Samples were measured according to Fourier Transform Infrared Spectroscopy (FTIR) using the Nicolet 6700 instrument. Infrared area near middle was chosen for determining fat and fatty acids. Mean fat content was found slightly higher value 1.53 g.100g-1 in experimental group opposite 1.49 g.100g-1 in control group showing no statistically significant difference (p >0.05). Ratio among saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) was 4.24:5.89:1 in experimental group and 3.75:5.13:1 in control group. Omega-3 PUFAs content was reached 0.54% in experimental group and 0.58% in control group showing no statistically significant (p >0.05). Near-perfect correlation was found between total PUFAs and omega-6 PUFAs as well in the experimental group and control group showing linear, positive and statistically significant relation (p <0.01, p <0.001). Ratio between omega-3 and omega-6 PUFAs was statistically significant (p <0.05) closer in experimental group 1:14.65 opposite ratio 1:16.78 in control group. Conclusion: comparable fat profile in the thigh muscle was achieved, showing no statistically significant difference (p >0.05), in addition to the correlation between total PUFAs and omega-6 PUFAs, which was statistically significant in control (p <0.001) and experimental groups (p <0.01), and statistically significant (p <0.05) closer relation between omega-3 and omega-6 PUFAs in experimental group.
Effect of Dividend on Stock Price: A Case of Fuel and Power Industries in Bangladesh
Authors: Islam Mir Md Nazrul
Published: April 2019

Dividend policy is an extensively researched topic in the arena of investments but still it remains an enigmatic that whether Dividend Policy affects the Stock Prices or not. The consequences of researches conducted in different stock markets are different. In Bangladesh, capital market investment is very essential and significant for the growth and market capitalization of domestic industry, trade and commerce. In current years Bangladesh had faced many precarious situations in its stock market. The Stock price reactions to the declaration of dividend of the fuel and power industry of Bangladesh are empirically examined. This study examines stock price reactions of listed dividend paying fuel and power industries in Dhaka stock exchange, Bangladesh for period of 11 years from of 2008-2018. This study will help us to make effective dividend decisions and effective implementation of dividend policies. In this study, Fixed Effect Model along with Random Effect Model have been used to estimate results. Both Models are implemented on panel data for explaining the association between dividend payments and share prices while controlling logarithm value of Profit after Tax, Earnings per Share and Return on Equity. The research is accompanied with a view to find whether the dividend announcement convey any evidence to the market that results a stock price volatility for adjusting the dividend announcement information while controlling the variables like Profit After Tax Earnings, Per Share and Return on Equity. The study also tested both the Models and found Random Effect Model is more significant than Fixed Effect Model. The result documented on the Random Effect Model shows that there are significant relationship with Retention Ratio, dividend per share and Return on Equity. In addition, Profit after tax shows the negative significant association and Earning per Shares insignificant with the share prices in Bangladesh Fuel and Power sector.

Metodologicamente, a pesquisa qualitativa caracterizou-se por um estudo de caso de múltiplas fontes de evidência (Yin, 2016), com três fases: entendimento de sistemáticas, compilação dos dados quanto à formação de portfólio e análise do produto final, a fim de esclarecer como ocorreu o processo de escolha do portfólio de projetos no Planejamento Estratégico 2017-2018, bem como traçar um perfil de formação de portfólio em relação ao alinhamento estratégico almejado pela ALRN. Os resultados apontaram para um alinhamento estratégico onde foram identificadas as fases de definição de eixos estratégicos, critérios de descarte e vinculação dos catorze projetos na criação do portfólio de projetos estratégicos. Contudo, registra-se, como ponto de atenção, a inclusão de projetos diretamente pela direção da instituição na fase final de definição do portfólio, fato este de risco para a manutenção do alinhamento, por não seguir a metodologia geral de construção do portfólio. Assim, o artigo visa contribuir nas discussões sobre o tema, ao partir de uma perspectiva de alinhamento estratégico onde se acrescenta uma discussão acerca da seleção dos projetos, de modo a garantir a devida prioridade dentro da organização, buscando a eficiência e eficácia em seus processos.
The importance of flavonoids in reducing blood pressure - selected aspects
Authors: Różańska Dorota , Regulska-Ilow Bożena
Published: April 2019

Hypertension is an independent risk factor for the development of cardiovascular disease. Therapy requires modifying the diet and lifestyle in order to reduce body weight. The role of flavonoids in reducing blood pressure also seems interesting. Flavonoids are plant compounds. The main classes of flavonoids are flavons, isoflavons, flavonols, flavanols, flavanones, and anthocyanins. Numerous epidemiological studies have reported that a higher intake of flavonoids in a diet is associated with a decreased risk of hypertension. One of the mechanisms by which flavonoids can help to reduce blood pressure is their activity as angiotensin-converting enzyme (ACE) inhibitors. Various flavonoids have a different ability to inhibit ACE, which is dependent on their chemical structure. The ACE inhibitor activity is associated with three structural elements of flavonoids: the catechol group on the B-ring, C2-C3 double bond and the cetone group in C4 at the C-ring. Flavonoids may exhibit ACE inhibitor activity because of compete with the substrate (competitive inhibition). One of the studies showed that flavonoid activity, as an ACE inhibitor, may be dependent on the ACE genotype (I/I, I/D, D/D). The vasodilatory properties of flavonoids can help lower blood pressure. Authors of numerous studies have shown that these properties are associated with different mechanisms, e.g. activation of potassium channels, regulation of extracellular and intracellular Ca2+ level, stimulation of nitric oxide synthase and increased synthesis of nitric oxide. Based on the studies presented in this paper, it can be concluded that flavonoids may play an important role both in preventing hypertension and in supporting its treatment.

This paper extends Jean-Luc Nancy’s engagement with St. Anselm. Specifically, while Nancy is primarily concerned with Anselm’s Proslogion, this paper brings Nancy’s deconstructive protocols to bear on Anselm’s Cur Deus Homo. Of particular interest is Nancy’s treatment of the semiological association of economics and metaphysics. Ultimately, the “supplemental logic” developed here allows us to read Anselm’s dependence on the category of debt in the context of prayer. Finally, by stressing Nancy’s reception of French literary theory and poststructuralism, this paper offers an intervention into the burgeoning theological reception of Nancy, which generally sees him as a basically anti-Christian philosopher of Heideggerian, not Derridean, immanence.

W artykule dokonano oszacowania wpływu pozyskiwania drewna na wybrane procesy naturalne i elementy środowiska w 15 nadleśnictwach w Karpatach Wschodnich, w tym na strukturę gleby i tempo erozji oraz na reakcję hydrologiczną w skali stoku i zlewni. Główny nacisk położony został na oszacowanie gęstości i przestrzennego układu dróg leśnych i szlaków zrywkowych oraz intensywności ich wykorzystania, ponieważ z przeglądu literatury wynika (por. Affek, 2019), że zrywka jest tym elementem procesu pozyskiwania drewna, który w największym stopniu oddziałuje na glebę i reakcję hydrologiczną zlewni górskich. Do badań wykorzystano wysokorozdzielcze dane LiDAR i dane leśne. Uzyskane wyniki wskazują, że ok. 5% analizowanego obszaru ma naruszoną strukturę gleby na skutek stosowanej naziemnej zrywki, przeważająca część powierzchni analizowanych oddziałów leśnych może być zagrożona skutkami efektu brzegowego powodowanego przez drogi, a gęstość dróg leśnych, z uwzględnieniem szlaków zrywkowych, należy do najwyższych notowanych w literaturze.

To investigate the effect of various transplanting dates on yield and yield attributing characteristics of Nerica rice mutants at drought prone areas, Ishurdi and Chapai Nawabgonj during aman season. Two advanced Nerica mutant lines (N4/350/P-4(5), N10/350/P-5-4) were evaluated compared with one check variety (Binadhan-17) with three dates of transplanting (D1=July 20, D2=July 30 and D3=August 10). The experiments were laid out on randomized complete block design (RCBD) with three replications. Twenty five days old seedlings were transplanted with optimum 20 x 20 cm row to row and plant to plant distance. The unit plot size was 3 m×4 m. The recommended doses of fertilizer were applied. The effect of dates of transplanting on grain yield of D3 was the highest (5.10 t ha-1) whereas D2 produced the lowest grain yield (4.24 t ha-1). Among the mutant lines/varieties, Binadhan-17 produced the highest grain yield (4.94 t ha-1) followed by N4/350/P-4(5) (4.57 t ha-1). The interaction effect of date and variety showed that Binadhan-17 produced the maximum yield (5.56 t ha-1) at D3 followed by N4/350/P-4(5) mutant (4.92 t ha-1). The interaction effect of date and location, D3 transplanting date produced the maximum yield (5.23 t ha-1) at Ishurdi which was followed by transplanting (4.96 t ha-1) at Chapai Nawabgonj. The interaction effect of variety and location Binadhan-17 produced maximum yield (5.06 t ha-1) in Ishurdi followed by Binadhan-17 in Chapai Nawabgonj (4.82 t ha-1). The interaction effect of date, variety and location transplanting date D3, Binadhan-17 produced maximum yield (5.70 t ha-1) in Ishurdi followed by transplanting date D3, Binadhan-17 in Chapai Nawabgonj (5.43 t ha-1). The data recorded on crop duration from transplanting to maturity revealed that the advanced mutant line N4/350/P-4(5) required the least average 108 days and the Binadhan-17 required maximum average 119 days. Therefore, 10th August was found to be the best date of transplanting and Binadhan 17 showed the best performance at Ishwardi in Bangladesh.

Controlled burning of rice husks at<700°C produced rice husk ash (RHA) which is predominantly amorphous silica (SiO2). RHA was used as a substitute for laterite and cement in proportions of 5%, 10%, 15%, 20%, 25% and 30% of concrete. The concrete was cured for 7 days, 14 days, 21 days, and 28 days respectively. It was observed that 20% of RHA provides the optimum strength. The effects of different particle sizes of 75, 150, 212, 300, 425 and 600 microns (µm) were tested using a compression test machine. A graph of average strength against particle size indicates 2.9 Nm-2 as the optimum strength at 75 µm and 1.2 Nm-2 as the minimum at 150 µm. From the ash size distribution, the presence of grains of several different sizes was observed. The grains were weighed using a weighing machine and a graph of particle size against percentage plotted to determine the particle size distribution. This showed that rice husk ash (RHA) is coarse grain material.

Coronary artery anomalies occur in 1.3-5.6% of patients undergoing coronary arteriography. An anomalous origin of LCX from right coronary sinus is the most common congenital variant. It is usually considered “benign” since it is not known to predispose individuals to sudden cardiac death. Such vessels are particularly predisposed to atherosclerotic disease in their proximal portion, due to the acute angulation of its origin from the aorta and its posterior retro aortic course. We present a case of 55 years old female admitted with acute coronary syndrome. Coronary angiogram showed the anomalous origin of the left circumflex artery from right coronary sinus. This artery had a significant lesion which was successfully stented with a drug-eluting stent.

Pearl millet is one of the major food crops in most of the arid and semi arid cropping region of India. Being the fourth most important cereal crop, pearl millet gives more nutrients and minerals to the rural people. The main purpose of the present study was to carry out an analysis of energy utilized during processing of pearl millet for preparing two different bakery products (i.e. cake and biscuits) under laboratory conditions. The present study was conducted at established lab. of Centre for Excellence, Pearl Millet, HAU, Hisar. In this lab, processing of pearl millet is done on regular basis for preparation of cakes and biscuits for demonstration as well as selling purpose through ATIC (Agriculture Technology and Information Centre) of HAU, Hisar. Pearl millet processing involves various unit operations such as cleaning, drying, milling, baking and packaging. Basically two types of energy i.e. manual and electrical were used during processing of pearl millet. Electricity was the main energy source for the value added products of pearl millet. Electricity was used to run electric oven, spiral mixer, dough maker, mill, packaging machine, lights etc. In pearl millet processing, some of the operations were done manually like, cleaning, sun drying, feeding of biscuits in package and weighing etc. Manual energy used was around 8% while electrical energy used was around 92%.

In this work we have reported an investigation on Hibiscus sabdariffa and Delonix regia dye extracts and their mixture as natural sensitizers for TiO2/DSCs. A shift in the absorption maximum toward the lower energy of the ultraviolet-visible spectrum was observed for the dye mixture and a shift in the absorption maximum towards the higher energy of the ultraviolet-visible spectrum was observed for the dye extracts. The optical band gaps obtained at the point where the absorption spectra showed strong cut offs range from 1.79eV to 2.40eV. Also, we have used TiO2 thin films of thickness 5.2μm and the Light Harvesting Efficiencies (LHE) of the dye extracts and the dye mixture adsorbed onto TiO2 surface were close to unity. The average diameter of the TiO2 films obtained from SEM is in the range of 25-40nm reflecting that the TiO2 films are transparent and suitable for DSC application. The XRD pattern revealed the TiO2 films to be of anatase form and the structure type is tetragonal with 3.53217Å as the d-spacing for the most prominent peak, 2θ=25.2139° (ICDD data file: 01-075-8897). Three (3) DSCs each of 0.52 cm2 active area were assembled and subjected to current-voltage characterization using a standard overhead Veeco viewpoint solar simulator equipped with AM 1.5 filter to give a solar radiation of 1000 W/m2 and coupled to Keithley source meter (model 4200SCS). The photoelectrochemical performance of the fabricated DSCs showed open-circuit voltages (Voc) varied from 0.42 to 0.53 V, the short-circuit current densities (Jsc) ranged from 0.10mAcm-2 to 0.90mAcm-2 and the fill factors (FF) varied from 12 to 38%. The best overall solar power conversion efficiency of 0.13% was obtained, under AM 1.5 irradiation and a maximum short circuit current density of 0.90mAcm-2. Nevertheless, pure Hibiscus sabdariffa and Delonix regia dye extracts proved to be rather poor sensitizers as can be seen by the low spectra absorption at lower energies with current densities of 0.17mAcm-2 and 0.10mAcm-2 respectively. The solar power conversion efficiencies for Hibiscus sabdariffa and Delonix regia dye extracts were 0.01% and 0.02% respectively. In our earlier studies, we highlighted an established fact that raw natural dye mixtures exhibit better performance than pure dye extracts. Thus, the power conversion efficiency of 0.13% observed for the dye mixture sensitized TiO2/DSC corresponds to an increment in the neighborhood of 85% to 92% over the pure dye extracts sensitized TiO2/DSCs.
