Improvement Approach for Matching PV-array and Inverter of Grid Connected PV Systems Verified by a Case Study
Authors: Omar Moien A. , Mahmoud Marwan M. 
Published: April 2021

Correct matching between PV array and inverter improves the inverter efficiency, increases the annual produced energy, decreases the clipping losses of the inverter, and prevent to a large extent the inverter frequent shut downs during clear sunny days of high solar radiation and low ambient temperature. Therefore, this paper presents a new methodology for selecting the appropriate peak power of the PV array with respect to the inverter output AC rated power taking into account the local daily distribution of solar radiation and ambient temperature. In addition, the proposed methodology specifies the appropriate number of PV modules in each string and the number of parallel strings connected to the input of the inverteraccording to its specifications and to PV cell temperature. Mathematically modeling of system parameters and components are presented and used in the simulation to investigate the different scenarios. The paper presents also a case study using simulation to find the optimal matching parameters of a PV array connected to an inverter with the specifications: 6 kW rated output power, an input mpp voltage range of 333-500 V, 6.2 kW maximum input DC power, and an output AC voltage of 230 Vrms. Considering the local climate conditions in West Bank, the simulation resulted a peak power of 7 kW for the PV array, which is greater than the inverter output power by the factor 1.16. In addition, the obtained PV array consists of two parallel strings each includes 12 PV modules connected in series while each PV module is rated at 290 W. The output voltage of the PV arrayvaries between 359 V to 564 Vat minimum and maximum temperature of 10 ˚C to 70 ˚C respectively. This PV array-inverter combination resulted by simulation an annual yield of 1600 kWh/kWp and an energy of 11197 kWh which corresponds to an energy gain of 1591 kWh/year more than using a PV array with a peak power of 6 kW as the inverter rated power.

Resumen

Objetivos
Las guías de práctica clínica (GPC) son recomendaciones desarrolladas de forma sistemática para ayudar a profesionales y pacientes en la toma de decisiones sobre la atención sanitaria más apropiada. Destacan entre sus características que deben basarse en la evidencia científica y estar elaboradas por equipos multidisciplinares. El objetivo de este estudio fue evaluar, en GPC, el contenido de la información sobre aspectos propios del laboratorio clínico y la participación de los profesionales del laboratorio en su elaboración.

Métodos
Se evaluaron 16 GPC recomendadas por la Sociedad Española de Medicina del Laboratorio (SEQC-ML) y/o seleccionadas en PubMed. En cada guía se evaluaron 80 aspectos relevantes relacionados con el laboratorio clínico y la autoría de profesionales del laboratorio.

Resultados
Las 16 guías evaluadas contenían de media un 49% (DE: 11%) de información sobre los aspectos específicos analizados del laboratorio clínico. Por orden de mayor a menor frecuencia contenían, una información media de: 69% de las variables postanalíticas analizadas (DE: 20%), 52% de las preanalíticas (DE: 11%) y 43% de las analíticas (DE: 18%). Finalmente, la mitad de las guías incluían algún profesional del laboratorio en la autoría.

Conclusiones
En las guías evaluadas fue frecuente observar carencias en la información sobre aspectos fundamentales del laboratorio clínico y únicamente la mitad de ellas incluía entre los autores a profesionales del laboratorio. Por ello, puede considerarse que todavía existe un margen de mejora amplio y sería recomendable una mayor incorporación de profesionales del laboratorio a los equipos multidisciplinares que las desarrollan.

Control of negative gain nonlinear processes using sliding mode controllers with modified Nelder-Mead tuning equations
Authors: E. Govinda Kumar , J. Arunshankar 
Published: April 2021

Abstract
This paper proposes a sliding mode controller (SMC) with modified Nelder-Mead tuning, for the control of nonlinear chemical processes, which are represented as first order plus dead time process with negative gain (FOPDT-NG). In the controller design, the SMC controller parameter in continuous part is obtained based on the time constant and dead time of the process, and controller parameters in the discontinuous part is obtained using Nelder-Mead tuning equations. Even though the controller parameters of conventional SMC are tuned using Nelder-Mead tuning, zero dynamics are noticed in the closed loop response of few FOPDT-NG processes and, with few other FOPDT-NG processes tracking of set-point is unachievable. This work proposes modification in the Nelder-Mead tuning equations using Nelder-Mead optimization to overcome the above disadvantages. Four different types of FOPDT-NG processes are considered in this work, and for every type the Nelder-Mead tuning equations are modified, for the design of proposed controllers. The performances of proposed controllers are evaluated for FOPDT-NG processes and also for three different chemical processes taken from literature. A simulation results demonstrate that, the proposed controller prevailed the performance of the conventional SMC in tracking the set-point and the elimination of zero dynamic behavior of FOPDT-NG processes. Hence, the proposed controllers provide improved closed loop performances as compared to the conventional SMC.

Abstract
The present study was carried out to investigate the beneficial and toxicological effect of plant-based titanium dioxide nanoparticles (TiO2 NPs) on the morphophysiological attributes of wheat plants under salinity stress. The biogenesis of titanium dioxide nanoparticles was accomplished by using the extract of Buddleja asiatica L. leaves followed by characterization through UV visible spectroscopy, SEM, FTIR, and EDX. NaCl salt was applied in two different concentrations after 21 days of germination followed by foliar applications of various concentrations of TiO2 NPs (20, 40, 60, 80 mg/L) to salinity-tolerant (Faisalabad-08) and salinity-susceptible (NARC-11) wheat varieties after 10–15 days of application of salt stress. Salinity stress showed remarkable decrease in morphophysiological attributes of selected wheat varieties. Magnificent improvement in plant height, dry and fresh weight of plants, shoot and root length, root and shoot fresh and dry weight, number of leaves per plant, RWC, MSI, chlorophyll a and b, and total chlorophyll contents has been observed when 40 mg/L of TiO2 NPs was used. However, the plant morphophysiological parameters decreased gradually at higher concentrations (60 and 80 mg/L) in both selected wheat varieties. Therefore, 40 mg/L concentration of TiO2 NPs was found most preferable to increase the growth agronomic and physiological attributes of selected wheat varieties under salinity.
Ernst Cassirer in Japanese Philosophy
Authors: Lofts Steve 
Published: April 2021

AbstractThe primary goal of this paper is not to argue for the “influence” of Cassirer, but rather to make known the reception of Cassirer in Japanese philosophy, illustrate the interconnection between Cassirer’s critique of culture and that of Japanese philosophy, and hopefully spark interest in what might be a fruitful dialog between Cassirer scholars and those working in Japanese philosophy. Historically, the paper defines Japanese philosophy and makes known its engagement with Western philosophy and the Marburg school of neo-Kantianism and its project of a critique of culture during its own self-development. Systematically, the paper points to the possible interconnection between Cassirer’s critique of culture and that of Japanese philosophy and makes the case for a mutually productive dialog between Cassirer scholars and those working in Japanese philosophy. Implicitly, the paper attempted to show that an engagement with Japanese philosophy from the perspective of a critique of culture forces us to question the Western dichotomy between philosophy and religion and the importance of this for the further development of a non-Eurocentric critique of culture. And by extension, that a critique of culture must be cognitive of the historicity of the culture from which it speaks.
Slime control in paper mill using biological agents as biocides
Authors: Pathak Puneet , Kumar Varun , Bhardwaj Nishi Kant , Sharma Chhavi 
Published: April 2021

Abstract
The environmental conditions of paper mills are suitable for the growth of slime-forming microorganisms due to the supply of nutrients, favorable temperature, and moisture. The slime formation causes the spoilage of raw materials & additives, breaks in the paper during papermaking, loss of production, reduces the hygienic quality of the end products, produces off-spec and rejected products, creates microbiological corrosion, and produces harmful gases. The main microorganisms are Bacteria (mainly Bacillus spp., Achromobacter spp., Enterobacter spp., Pseudomonas spp., Clostridium, etc.), Fungi (Aspergillus, Penicillium, Saccharomyces, etc.), and Algae. Besides the use of conventional toxic chemical biocides or slimicides, slime formation can also be controlled in an eco-friendly way using enzymes, bacteriophages, biodispersants, and biocontrol agents alone or along with biocides to remove the slime. Enzymes have shown their effectiveness over conventional chemicals due to nontoxic and biodegradable nature to provide clean and sustainable technology. Globally enzymes are being used at some of the paper mills and many enzymatic products are presently being prepared and under the trail at laboratory scale. The specificity of enzymes to degrade a specific substrate is the main drawback of controlling the mixed population of microorganisms present in slime. The enzyme has the potential to provide the chemical biocide-free solution as a useful alternative in the future with the development of new technologies. Microorganisms control in the paper mill may appear as a costly offer but the cost of uncontrolled microbial growth can be much higher leading to slime production and large economic drain.

Published: April 2021

Abstract
The paper is focused on computation of stable periodic solutions to systems of delay differential equations modelling the dynamics of infectious diseases and immune response. The method proposed here is described by an example of the well-known model of dynamics of experimental infection caused by lymphocytic choriomeningitis viruses. It includes the relaxation method for forming an approximate periodic solution, a method for estimating the approximate period of this solution based on the Fourier series expansion, and a Newton-type method for refining the approximate period and periodic solution. The results of numerical experiments are presented and discussed. The proposed method is compared to known ones.
Analysis of the predictability of stratospheric variability and climate indices based on seasonal retrospective forecasts of the INM RAS climate model
Authors: Vorobyeva Vasilisa V. , Volodin Evgenii M. 
Published: April 2021

Abstract
Ensemble numerical experiments for winter seasons of 1980–2014 were carried out with the use of the mathematical climate model of the Institute of Numerical Mathematics (INM) of the Russian Academy of Sciences developed initially for multi-year climate forecasts. Based on the results obtained in this research, a qualitative assessment of the reproduction of the North Atlantic (NAO) and Pacific-North American (PNA) oscillation indiceswas obtained. It was shown that the INM-CM5-0 climate model has a very high predictability of the winter NAO index and one, but not unique reason for this is the predictability of the stratospheric variability in the INM RAS model. The analysis of the quality of reproduction of the PNA index on a seasonal time scale for the INM-CM5-0 model has shown an acceptable result.
Parallel- vs. Wechselflexion im dat sg mask/neutr – Ein Erklärungsansatz zur Persistenz der Variation
Authors: Sahel Said 
Published: April 2021

AbstractThis paper deals with the variation of adjective inflection in nominal phrases with two consecutive adjectives in the dative singular masculine/neuter (e. g.mit größerem politischem[strong inflection]Einfluss vs. mit größerem politischen[weak inflection]Einfluss‚with greater political influence‘). Only the second adjective is affected by the variation; it can show strong or weak inflection (parallel inflection vs. alternating inflection). In Standard German, both uses coexist without any difference in meaning or function. This phenomenon is analyzed using corpus data. The focus is on the question why this variation persists almost exclusively in the dative singular masculine/neuter. After the discussion of different explanations available, a phonological approach to explain the persistence of the variation is presented. It is argued that the low phonological contrast between the strong inflection -mand its weak counterpart -nis the reason why the variation is still persistent in the dative singular masculine/neuter. The role of grammar reference works in the persistence of the concerning variation is also discussed.
