Optimized Direct Instantaneous Torque Control for SRMs With Efficiency Improvement

This article proposes an optimized direct instantaneous torque control (DITC) scheme for switched reluctance motor (SRM) drives with a novel adaptive dynamic commutation strategy, which can effectively reduce torque ripple and improve system efficiency. To minimize torque ripple, two operational modes are developed for torque tracking during commutation regions. In Mode I, the torque error is compensated by the outgoing phase during the current buildup region of the incoming phase; in Mode II, the torque error is compensated by the incoming phase during the demagnetization region of the outgoing phase. To implement the proposed DITC scheme in a more effective conduction range, the commutation instants are dynamically adjusted according to the varied operation conditions. For each phase, the turn-on and turn-off angles are modified in each electrical cycle by a torque error regulator and a phase current endpoint detector, respectively. By employing the proposed strategy, the torque generation capability is fully utilized for minimized torque ripple, and the phase currents work within a more effective conduction range for improved system efficiency. The simulation and experiments on a three-phase 12/8 SRM are carried out to verify the feasibility and effectiveness.
Growth responses and yield of heterotis (Heterotis niloticus) on artificial diet

The growth responses and yield of Heterotis niloticus on artificial diets of varying protein levels were studied in a bid to assess the implication of feeding Heterotis in intensive fish production venture for a rearing period of 84 days. One hundred and twenty juvenile H.niloticus were fed for 12 weeks on 28%, 31%, 34% and 37% dietary crude protein levels. The fish were reared in 4 concrete tanks stocked at the rate of 10 fish per M super(2) 100,00/hectare). Consequently, the weight gain, food conversion ratio, serum protein and albumin-globulin ratio were determined to assess the growth and state of health of the fish. The yield was appraised through economic considerations of cost of production of fish and diets (feed). The varying crude protein levels significantly influenced mean weight gain, percentage weight gain and food conversion ratio however, the 37% crude protein in diet produced the best growth. The serum protein was highest in fish raised on 31% crude protein diet while the highest value was recorded for albumin-globulin ratio on diet containing 34% crude protein. The yield from treatments 1, 2, 3, and 4 were 114.38 of/84 days 571.9kg/g hect);146.79g/84 days 733.95kg/hect), respectively. However, treatment 3 recorded the highest value for profit index
Budgetary Policy and Economic Growth in the Republic of Congo

The purpose of this work is in the field of public finance through an exploration of statistical data spreading from 2004 to 2018 the methodological approach is based on an economic model. We note the existence of a positive relationship between the instruments of fiscal policy and economic growth as measured by gross domestic product (GDP). It is oil revenues, non-oil revenues, Operating expenses, Public expenditure, and private investment that are significant and positively impact economic growth through nominal GDP. This requires attention to be focused on the fiscal policy of the oil sector and the strengthening of the non-oil sector so that fiscal policy is efficient and allows the accumulation of factors of production.
Type of Employment as the Most Important Factor of Economic Growth

—The labor force has a number of essential characteristics that can be classified, on the one hand, into quantitative and qualitative, and on the other, in accordance with the phases of reproduction. Based on the set of characteristics, it is possible to classify the labor force into basic, producing traditional products, and pioneer, producing innovative products. Identifying the influence of employment on the dynamics of GDP and the type of economic growth, it is proposed to distinguish two types of employment: flexible and rigid. The relevance of this article is to identify the influence of the type of employment and the possibility of achieving positive economic growth on a qualitative basis in the long-term perspective. On the basis of theoretical study of types of labor and types of employment a comparative analysis has been carried out for the countries of Great Seven, Russia and China to identify reproduction peculiarities of labor power in these countries and to justify their impact on economic growth. A grouping of the studied countries by type of employment was proposed according to the type of employment based on the ratio of GDP dynamics and the dynamics of the number of consumed workforce. As a result, the type of employment of labor force is closely related to the parameter of labor productivity, which significantly affects the dynamics of national production.

Unravelling the roles of two senescent enhanced MYB transcription factors in the regulation of anthocyanin biosynthesis in Arabidopsis thaliana

MYB90 and MYB75 are two MYB transcription factors that regulate anthocyanin biosynthesis in Arabidopsis. Prior to this study a microarray experiment indicated that MYB90 was required for senescence associated anthocyanin biosynthesis. The role of MYB90 during senescence was investigated using a MYB90 knockout insertion mutant, IM28. Gene expression studies at different time points during the development of the seventh rosette leaf showed that MYB90 regulates anthocyanin biosynthesis genes and MYB75 during senescence. The absence of MYB90 expression reduced photosynthetic performance at two time points during development. Analysis of anthocyanin and flavonoid content showed that there was reduced anthocyanin biosynthesis in the absence of MYB90 expression. The role of MYB90 and MYB75 during high light stress was investigated by analysing the photosynthetic performance and anthocyanin content of high light treated IM28 and MYB75 RNAi plants. MYB90 is required for increased resistance during high light stress, which reflected anthocyanin levels. However, there was eventual compensation for the absence of MYB90 expression in prolonged high light stress. MYB75 was also required for increased resistance to high light stress, but this was not reflected in the anthocyanin levels. The spatial and temporal regulation of MYB90 and MYB75 was investigated using transgenic plants containing promoter: GUS fusions. MYB90 promoter activity was mainly localised to vascular tissue during senescence and low nitrogen/high glucose treatment. MYB75 showed differential tissue specificity in different treatments. The transcriptional regulation of the MYB90 promoter was analysed using promoter deletion GUS: fusions. A senescence specific activation region and a repressor region of the promoter were identified.
Electrospun Bilayer PAN/Chitosan Nanofiber Membranes Incorporated with Metal Oxide Nanoparticles for Heavy Metal Ion Adsorption

Bilayer nanofiber membranes with enhanced adsorption and mechanical properties were produced by combining a layer of polyacrylonitrile (PAN) functionalized with metal oxides (MO) of ZnO or TiO2 with a layer of chitosan (CS) via consecutive electrospinning. The adsorption properties of the bilayer PAN/MO–CS nanofiber membranes against lead (Pb(II)) and cadmium (Cd(II)) ions were investigated, including the effects of the solution pH, initial ion concentrations, and interaction time. The integration of a CS layer into PAN/MO nanofibers increased the adsorption capacity of lead by 102% and cadmium by 405%, compared to PAN/MO single layer. The nonlinear optimization method showed that the pseudo-second-order kinetic model and Langmuir isotherm equation better described the adsorption results. More importantly, the incorporation of a supportive CS nanofiber layer enhanced the tensile strength of PAN/MO–CS bilayer by approximately 68% compared to the PAN/MO single layer, owing to the strong interaction between the fibers at the interface of the two layers.
Fabrication and Development Low Cost Dual Axis Solar Tracking System

Solar energy is gaining importance day by day as an energy resource. By sun tracking we can increase the electric energy of solar panel. When the solar panel is perpendicular to the sun’s rays it receives more sunlight. This paper about follow the sunlight direction across the sky by using a DC motor(satellite motor), the LM324 IC control the movement of DC motor by this the solar panel will change their position, solar panel detects the sunlight using four light dependent resistors (LDRs). The objective is to design and implement an automatic solar-tracking mechanism using an embedded system design with minimum cost and reliable structure. The results presented in this review confirm that the azimuth and altitude dual axis tracking system is more efficient compared to other tracking systems.
Development of new poly(ADP-ribose) polymerase (PARP) inhibitors in ovarian cancer: Quo Vadis?

Epithelial ovarian cancer (EOC) is the fifth leading cause of cancer mortality among women, potentially due to ineffectiveness of screening tests for early detection. Patients typically present with advanced disease at diagnosis, whereas, up to 80% relapse and the estimated median progression-free survival (PFS) is approximately 12–18 months. Increased knowledge on the molecular biology of EOC resulted in the development of several targeted therapies, including poly(ADP-ribose) polymerase (PARP) inhibitors. These agents have changed the therapeutic approach of the EOC and exploit homologous recombination (HR) deficiency through synthetic lethality, especially in breast cancer genes 1 and 2 (BRCA1/2) mutation carriers. Furthermore, BRCA wild-type patients with other defects in the HR repair pathway, or those with platinum-resistant tumors may obtain benefit from this treatment. While PARP inhibitors as a class display many similarities, several differences in structure can translate into differences in tolerability and antitumor activity. Currently, olaparib, rucaparib, and niraparib have been approved by Food and Drug Administration (FDA) and/or European Medicines Agency (EMA) for the treatment of EOC, while veliparib is in the late stage of clinical development. Finally, since October 2018 talazoparib is FDA and EMA approved for BRCA carriers with metastatic breast cancers. In this article, we explore the mechanisms of DNA repair, synthetic lethality, efficiency of PARP inhibition, and provide an overview of early and ongoing clinical investigations of the novel PARP inhibitors veliparib and talazoparib.
Movement Disorders in Genetic Pediatric Ataxias

Genetic pediatric ataxias are heterogeneous rare disorders, mainly inherited as autosomal‐recessive traits. Most forms are progressive and lack effective treatment, with relevant socioeconomical impact. Albeit ataxia represents the main clinical feature, the phenotype can be more complex, with additional neurological and nonneurological signs being described in several forms.

Health Monitoring of Human Multiple Physiological Parameters Based on Wireless Remote Medical System

Telemedicine, as a new technical means and medical model, can truly realize the sharing and monitoring of telemedicine information, and ultimately ensure that everyone has equal access to medical and health resources. Based on the research on the status of telemedicine application and wireless communication technology, this paper proposes a multi-physical parameter wireless telemedicine health monitoring system solution, and analyzes the overall structure and functional requirements of the system. Human physiological parameters of the wireless remote medical system for health monitoring include body temperature, respiration, blood oxygen saturation, pulse, blood pressure, and electrocardiogram. In this paper, fabric electrodes are used to extract human bioimpedance signals, discrete Fourier transform algorithm is used to detect human respiratory signals, and respiratory rate is detected based on dynamic differential threshold peak detection technology. The reflection type photoelectric sensor is used to realize the reflection of the human pulse signal, and the continuous measurement of the cuff-free blood pressure based on the pulse wave conduction time is combined with the ECG (Electrocardiogram) data. A self-learning threshold algorithm based on near-infrared photo plethysmo graphy signal trough detection is designed on the reflective blood oxygen saturation calculation algorithm. The difference threshold method is used to extract the QRS band feature points. We tested the overall operation of the system. The results show that the collected human physiological signal data is accurate. After a series of tests, the validity and reliability of the collected physiological signals have been proven.
Advances in tuberculosis in 2019 in Canada and globally

Tuberculosis (TB) continues to be an important public health and clinical concern in Canada, leading the Public Health Agency of Canada to establish a target of TB elimination by 2035. Although TB rates have declined over the past 30 years, between 2005 and 2017, the rate of decline slowed to an average of only 1% annually over those years. By contrast, in the same time period in the United States, the average annual rate of decline exceeded 5% annually. This persistence is accompanied by enormous disparities in rates of TB in various populations in Canada. One affected population that continues to be disproportionately affected by TB is the Indigenous populations. The disparity between the rates of the Indigenous population and non-Indigenous Canadian-born population has actually widened over the past 20 years. In 1991, the incidence of active TB among the Indigenous populations was 10 times higher than the rate among the Canadian-born, nonIndigenous population. In 2017 the rate was more than 40 times higher. Among the Inuit in Nunavut and Nunavik, rates have increased more than tenfold over the past 2 decades with major epidemics affecting many communities. This has been attributed to the disparities in social determinants of health, particularly crowded housing. The other population affected by TB is the foreign-born, who contributed to more than 70% of all TB cases in Canada over the past decade. In part, this reflects migration of persons who reactivate in Canada, after migrating here with latent tuberculosis infection (LTBI) from countries with high incidence of TB disease and high prevalence of LTBI. They come from the vast global pool with LTBI, estimated to be close to one-quarter of the entire world’s population. Among migrants to Canada, the impact of current immigration screening efforts is modest. Of all foreign-born children and adolescents diagnosed with active TB in Ontario between 2002 and 2011, only 8% were detected through immigration screening referrals. In Alberta, Long and colleagues found that the immigration screening program had minimal public health impact and concluded that the current TB immigration screening system in Canada was “fundamentally flawed. ”
Effet de l’équilibre potassium-azote en fertigation sur la productivité et la qualité de trois variétés de fraise

Résumé L’objectif du présent travail de recherche est d’évaluer l’équilibre potassium-azote sur les paramètres de production et de qualité des trois principales variétés de fraise au Maroc (Fortuna, San Andreas et Sabrina). L’expérimentation a été conduite durant la campagne 2017-2018 en deux essais: 1) en serre de production à la sation expérimentale de l’INRA-Larache, 2) en hors sol à la serre expérimentale de l’Institut Agronomique et Vétérinaire Hassan II, Rabat. Les programmes de fertilisation testés ont un équilibre K2O/N croissant durant la phase végétative: 1,2; 1,7; 2,4; 3,0 et décroissant durant la phase de production: 2,0; 1,7; 1,1; 0,9. La fertilisation totale en N, P, K, Ca et Mg est identique pour tous les traitements. Le dispositif expérimental est un split-plot à trois répétitions. Les résultats ont montré qu'un programme avec les ratios 2,4/1,1 était supérieur aux autres programmes en améliorant les paramètres de productivité et de qualité des fraises. L'apport d'une solution nutritive avec un rapport K2O/N de 2,4 durant la période végétative et 1,1 durant la période de production de fruits a augmenté le taux de chlorophylle de 12,7%, le calibre des fruits de 9%, le rendement de 2,3 T/ha (6%) et la teneur en sucre de 13%. Le programme de fertilisation avec un K2O/N de 2,4/1,1 devrait être adopté pour améliorer la productivité et la qualité des fraises marocaines.
ULTRA-COMPACT BALANCED MULTIBAND FULLY RECONFIGURABLE BANDSTOP FILTER

This paper introduces a balanced (differential) multiband reconfigurable (tunable) bandstop filter (BSF) using all lumped elements. The main features of the design include its ultra-compact size as well as flexibility to control any frequency band independently in terms of both center frequency and absolute bandwidth (ABW). In the proposed structure, the corresponding non-resonating nodes (NRN) of the symmetrical bisections are connected to N number of LC π-circuits (N-band cell) through capacitors. Again, in each symmetrical bisection, K number of NRNs are series cascaded through LC π-circuits. This results in a Kth order N-band stopband (notch) response in differential mode (DM) operation whereas provides a passband response when excited by a common mode (CM) signal. Reconfiguration of any DM stopband is obtained by using tunable capacitors for the corresponding LC π-circuit in each N-band cell and also, for its coupling capacitors to the NRNs. To validate the proposed topology, a dualband differential tunable BSF is designed and fabricated where both DM stopbands are controlled independently in the range of 1.16 GHz–1.32 GHz. Also, the bandwidth of each band is varied independently by 20–50 MHz without affecting the other band. At any tuning state, DM stopband rejection for each band is found to be ≥ 19 dB, resulting in a minimum CMRR value of 19 dB. The fabricated prototype occupies an area of 0. 13λg × 0. 04λg (21mm × 7 mm) where λg is the guided wavelength at the center frequency of the entire spectral range, and the experimental results show a good agreement with the simulation results.
Organising experience of informal sector workers – a road less travelled

This paper uses the Social Identity Model of Collective Action (SIMCA) framework of Zomeren et al. (2008) to explain the organising experiences of the informal sector workers engaged in large number in the world's largest shipbreaking industry located in the western Indian town of Alang. ,A single case study approach was adopted to understand the participation of shipbreaking workers in their trade union and factors that influence their participation. ,Sense of cohesive collective identity and injustice alongside efficacy considerations have shaped the organising experiences and affected the participation of informal sector workers in their union. The trade union was able to overcome the scourge of invisibility that has been one of the dominant features of informal sector employment. ,This paper treated union participation as unidimensional. Besides, the subjective conceptualization of strengths of perceptions of injustice, identities and efficacy considerations could be a limitation. The paper does acknowledge the gendered nature of shipbreaking but have not actively pursued it as a part of our research. ,The findings of our study are an exemplar for those who intend to organise informal sector workers, especially precarious workers. The empirical findings allude to the role of trade unions in combating the invisibility, which is one of the defining features of informal sector workers through a distinctive, cohesive identity inculcated in those workers. ,This paper has borrowed the SIMCA framework to explore union participation. Organising experiences of precarious workers from the developing world provides a contextual and an empirical novelty to our study.
