Modeling and Performance Analysis of a Grid-connected Polycrystalline Silicon Photovoltaic System under the Maritime Climate of El Jadida in Morocco

Renewable energy sources (RES) have been extensively deployed as green energy producers for reducing power consumption while diminishing greenhouse emissions. Nowadays, Morocco focuses on RES, especially solar energy due to its abundance, in order to reduce its dependence on fossil products (e.g., coal, oil, gas). The aim of the work presented in this article is the modeling, the simulation, the experimentation and the assessment of the performance of a 2.040 kWp grid-connected photovoltaic (PV) system. It is based on polycrystalline silicon technology (pc-Si) and installed on the flat roof of the Physics department building of the Faculty of Sciences El Jadida (Latitude 33.22°N, Longitude 8.48°W, Altitude 24 m, and 2.1 km away from the Atlantic Ocean) in Morocco. Thus, the daily and monthly characteristics of the PV system (e.g., power, voltage, current) have been measured, monitored, and analyzed during three years (January 2015-December 2017). Besides, several simulations and experiments have been carried out and the results have been reported and showed that the simulation gives a good approximation of the real-world scenarios. Therefore, the monthly average of the produced energy, the efficiency, the final and the reference yields ( Y F and Y R ), the performance ratio ( PR ), and the annual capacity factor ( CF ) of the PV system have been computed, presented and evaluated in order to assess its performance. For our pc-Si PV system, the average annual values of the produced energy, the PR and the CF are 1830 kWh/kWp, 79% and 0.21 respectively.
VISUAL APPEAL MODEL FOR CONSUMER ONLINE IMPULSIVE PURCHASES IN INDONESIA

This article analyzes the online impulsive purchases. Visual appeal, perceived enjoyment and purchase intention are the exogenous variables. The quantitative research is used in this study with descriptive analysis methods. The samples are 100 consumers who have shopped at the top four online stores in Indonesia (Lazada, Blibli, Tokopedia, Elevenia) and analyzed using path analysis. The results show that visual appeal has a negative influence on purchase intention and consumer online impulsive buying, while visual appeal has an influence on perceived enjoyment. Perceived enjoyment has an influence on purchase intention but has a negative influence on consumer online impulsive buying. Purchase intention has an influence on consumer online impulsive buying. Perceived enjoyment is the most influences variable on purchase intention compared to visual appeal, while the most influential variable on consumer online impulsive buying is purchase intention compared to visual appeal and perceived
Glycolytic and Proteolytic Metabolism in Erythrocytes from Elderly and Demented Patients

Background: Accumulating evidence implicates a role for altered energy and proteolytic metabolism in the pathogenesis of Alzheimer disease (AD), but the involvement of erythrocytes (RBC) remains to be completely understood. The objective stands to test a hypotheses that erythrocytic glycolytic and proteolytic metabolism is disturbed in the elderly and in AD patients. Methods: This pilot study analyzed the levels of the key glycolytic and proteolytic enzymes and metabolites in RBC from patients with AD and non-Alzheimer’s dementia (NA), from age-matched (AC) and young adult (YC) controls. Results: Glycolytic enzymes displayed lower activities in AC, and similar or higher activities in AD and NA, as compared to those in YC. Caspase-3 and calpain activities in AC were about 3 times those of YC. There were no differences between AC, AD and NA in proteolytic enzymes. Conclusion: Among glycolytic parameters studied in four subject groups, only hexokinase activity specifically increases in AD. Changes in other glycolytic and proteolytic enzyme activities and metabolite concentrations in RBC were not specific to dementias but characteristics for aging.
IMPACTS OF USING YEAST, IODINE AND THYROXIN IN SEA BREAM (SPARUS AURATA) DIETS ON FISH PERFORMANCE

This study was conducted to investigate the effect of adding either brewer yeast as a probiotic, iodine or thyroxin with yeast as synbiotics to sea bream (Sparus aurata)fingerlings diets on; growth performance, feed utilization, body composition, biometric measurements indices and some serum constituents of sea bream. Acclimatized fish were randomly distributed in 12 glass aquaria and stocking density was 15 fish per aquarium with an average weight 1.9±0.1 g/fish as triplicate groups per treatment. The 1st group was considered as a control which fed on the basal diet (C). Three tested diets are formulated by adding 2g yeast/kg diet (Y), 2g yeast+0.01g potassium iodide/kg diet (YI) and 2g yeast+0.05 g thyroxin /kg diet (YT4) respectively for second, third and fourth groups. In the present work, addition of yeast with thyroxin followed by yeast alone to sea bream (Sparus aurata) fingerlings diets significantly improve growth performance, feed utilization efficiency and the fish biochemical composition comparing with the control one. The lowest growth performance and feed utilization values were recorded in fish fed diet supplemented with iodine when compared with corresponding values in fish of control group. Results of biometric measurements showed that adding iodine to fish diet significantly reduced gut length. Adding either iodine or thyroxin significantly increased serum lipase and decreased amylase contents.
Agroforestry Benefits and Challenges for Adoption in Europe and Beyond

Soil degradation is a global concern, decreasing the soil’s ability to perform a multitude of functions. In Europe, one of the leading causes of soil degradation is unsustainable agricultural practices. Hence, there is a need to explore alternative production systems for enhanced agronomic productivity and environmental performance, such as agroforestry systems (AFS). Given this, the objective of the study is to enumerate the major benefits and challenges in the adoption of AFS. AFS can improve agronomic productivity, carbon sequestration, nutrient cycling, soil biodiversity, water retention, and pollination. Furthermore, they can reduce soil erosion and incidence of fire and provide recreational and cultural benefits. There are several challenges to the adoption and uptake of AFS in Europe, including high costs for implementation, lack of financial incentives, limited AFS product marketing, lack of education, awareness, and field demonstrations. Policies for financial incentives such as subsidies and payments for ecosystem services provided by AFS must be introduced or amended. Awareness of AFS products must be increased for consumers through appropriate marketing strategies, and landowners need more opportunities for education on how to successfully manage diverse, economically viable AFS. Finally, field-based evidence is required for informed decision-making by farmers, advisory services, and policy-making bodies.
Green Bonds vs Regular Bonds: Debt Level and Corporate Performance

This paper compares the effectiveness of traditional and green bonds for corporate performance among globalcompanies which issue these types of bonds. Our research represents a first attempt to provide an original empiricalcontribution with a specific focus on the influence of green debt levels on corporate performance. We develop aframework for the analysis of the influence of the debt level on corporate performance, and also compare the influence ofvarious types of bonds issuance on several indicators of corporate performance.Our data refer to 118 companies from various industries and countries, including 17 companies issuing green bonds inthe period from 2013 to 2017. We study the impact of debt levels on some standard corporate performance indicators,such as ROA, ROE, Revenue/Assets, EBITDA/Assets and EBIT/Assets.Our results show that bond issuance has a positive effect on corporate performance. In particular, the relationshipbetween debt levels and corporate performance is described in a non-linear way (an inverse U-shape), i.e., as debt levelincreases, the firm’s corporate performance grows, but only up to a certain point where the largest positive effect isachieved. Moreover, we find that the issuance of green bonds has a larger positive impact on corporate efficiency thantraditional bonds and the growth in the share of green financing in the total company’s debt has a positive impact oncorporate performance.This study opens up avenues for further research in the field, and combining our approach to evaluating the effect ofgreen bonds on corporate performance with an examination of companies arranged according to their life cycle stagewould be intriguing. However, at the present stage of development of the green bonds market it is impossible to studytheir influence on corporate performance as the research selection is rather small, and this market has emerged ratherrecently.
Observations of precipitation energies during different types of pulsating aurora

Abstract. Pulsating aurora (PsA) is a diffuse type of aurora with different structures switching on and off with a period of a few seconds. It is often associated with energetic electron precipitation (>10 keV) resulting in the interaction between magnetospheric electrons and electromagnetic waves in the magnetosphere. Recent studies categorize pulsating aurora into three different types – amorphous pulsating aurora (APA), patchy pulsating aurora (PPA), and patchy aurora (PA) – based on the spatial extent of pulsations and structural stability. Differences in precipitation energies of electrons associated with these types of pulsating aurora have been suggested. In this study, we further examine these three types of pulsating aurora using electron density measurements from the European Incoherent Scatter (EISCAT) VHF/UHF radar experiments and Kilpisjärvi Atmospheric Imaging Receiver Array (KAIRA) cosmic noise absorption (CNA) measurements. Based on ground-based all-sky camera images over the Fennoscandian region, we identified a total of 92 PsA events in the years between 2010 and 2020 with simultaneous EISCAT experiments. Among these events, 39, 35, and 18 were APA, PPA, and PA types with a collective duration of 58, 43, and 21 h, respectively. We found that, below 100 km, electron density enhancements during PPAs and PAs are significantly higher than during APA. However, there are no appreciable electron density differences between PPA and APA above 100 km, while PA showed weaker ionization. The altitude of the maximum electron density also showed considerable differences among the three types, centered around 110, 105, and 105 km for APA, PPA, and PA, respectively. The KAIRA CNA values also showed higher values on average during PPA (0.33 dB) compared to PA (0.23 dB) and especially APA (0.17 dB). In general, this suggests that the precipitating electrons responsible for APA have a lower energy range compared to PPA and PA types. Among the three categories, the magnitude of the maximum electron density shows higher values at lower altitudes and in the late magnetic local time (MLT) sector (after 5 MLT) during PPA than during PA or APA. We also found significant ionization down to 70 km during PPA and PA, which corresponds to ∼200 keV of precipitating electrons.
Sorbitol versus sucrose as photosynthesis and translocation products in developing apricot leaves

Very young apricot leaves behave like the young leaves of most plants; that is, [14C]sucrose is formed as the main product of 14CO2 photosynthesis, and also when the leaves are supplied with [14C]glucose. [14C]sorbitol is not produced, and is poorly metabolized when fed to the leaf. Expanding leaves behave differently: [14C]sorbitol and [14C]sucrose are formed in similar amounts from both 14CO2 and [14C]glucose; and when [14C]sorbitol is supplied, it is readily metabolized and utilized for growth. Mature leaves are different again. They form [14C]sorbitol as the main product from 14CO2 and from [14C]glucose, and they do not metabolize [14C]sorbitol at all. Thus during development, apricot leaves gain but then lose the ability to utilize sorbitol. They also gain and keep the ability to synthesize sorbitol. This suggests that different biochemical paths exist for sorbitol formation and utilization, and that these paths are differently developed in the various stages of leaf development. Although the very young leaves did not synthesize sorbitol from CO2 or glucose, they contained it as their major sugar. Translocation behaviour was therefore studied. Neither the very young leaves nor the expanding leaves export any photosynthate, but the mature leaf rapidly translocates carbohydrate, mainly in the form of sorbitol, to the younger leaves as well as the rest of the plant. [14C]sorbitol supplied to the mature leaf can be recovered in that form from the very young leaf on the same shoot. This further establishes the role of sorbitol in apricot as a specific transport carbohydrate.
Personality and coping. What traits predict adaptive strategies

espanolEl manejo y las estrategias utilizadas desempenan un papel esencial en la adaptacion a los cambios, y los rasgos de la personalidad son factores predictivos importantes de estas estrategias. El objetivo de este estudio es estudiar que rasgos predicen diferentes estrategias de afrontamiento en adultos mayores. Los participantes fueron 226 adultos mayores (60 a 88 anos). Los instrumentos utilizados fueron el NEO-FFI para evaluar la personalidad y el Cuestionario de estrategias de afrontamiento (CAE). Se realizaron modelos de regresion lineal multiple. El neuroticismo predijo positivamente las estrategias orientadas a la emocion: autofocalizacion negativa, expresion abierta de emociones, evitacion y religion. Las estrategias orientadas a los problemas fueron predichas positivamente: apertura a la experiencia (resolucion de problemas), la amabilidad (reevaluacion positiva) y la responsabilidad (resolucion de problemas y reevaluacion positiva). Ademas, la amabilidad y la responsabilidad predijeron de manera negativa las estrategias orientadas a la emocion: expresion emocional abierta y autofocalizacion negativa. La extraversion no predijo ninguna estrategia de afrontamiento. Estos hallazgos muestran que el neuroticismo es un rasgo desadaptativo durante el envejecimiento, mientras que la apertura a la experiencia, la amabilidad y la conciencia son rasgos adaptativos en los adultos mayores. EnglishCoping and strategies used play an essential role in the adaptation to changes, and personality traits are important predictors of these strategies. The aim of this study is to find out what traits predict different coping strategies in older adults. Participants were 226 older adults (60 to 88 years old). Data on personality and coping strategies were obtained through the NEO-FFI and the Coping Strategies Questionnaire. Multiple linear regression models were conducted. Neuroticism positively predicted emotion-oriented strategies: negative self-focused, overt-emotional expression, avoidance, and religious. Problem-oriented strategies were positively predicted by openness to experience (problem-solving focused), agreeableness (positive reappraisal), and conscientiousness (problem-solving focused and positive reappraisal). In addition, agreeableness and conscientiousness negatively predicted emotion-oriented strategies: overt-emotional expression and negative self-focused. Extraversion did not predict any coping strategy. These findings show that neuroticism is a maladaptive trait during aging, whereas openness to experience, agreeableness, and conscientiousness are adaptive traits in older adults.
Making a virtue of necessity? The economics and politics of the ECB’s monetary policy, 1999-2019

The ECB could hardly afford political neutrality, even in the monetary union’s “honeymoon phase”. Being a stateless central bank entailed striking compromises between confl icting (national) monetary policy preferences. However, such compromises would often be reached at the expense of theoretical consistency and to the detriment of coherence in the ECB’s monetary policy strategy. And, perhaps inevitably, they would also bear the mark of the dominant partner in the European Monetary System, that is prior to the establishment of the monetary union, now also being the biggest subscriber to the ECB’s capital. Political neutrality and, for that matter, monetary activism on the part of the ECB -as well as liquidity in the euro-area- were largely inadequate during the euro area crisis, especially in its early phase. They were subsequently increased, but at a slow pace and in a preferential fashion, that is, largely to the benefi t of the banking industry. Eventually, the ECB did try to make a virtue of necessity; yet, this could only go so far. Thus, the ECB has reluctantly become the only game in town, its reluctance being mostly associated with the overriding concerns of certain national central banks of the Eurosystem, most notably the Bundesbank; namely, ensuring monetary dominance, averting (at that time illusory) infl ationary dangers, preventing moral hazard, enforcing structural reforms and, not least, fending off any, indirectly emerging, type of transfer union. Therefore, the ECB could have no great ambitions; its lonely game was unlikely to produce a medal-winning policy maker in the world championship of central banking.
Treatment of cutaneous field cancerization

The cutaneous field cancerization corresponds to an area of skin chronically exposed to the sun. It contains actinic keratoses and other skin signs of photodamage caused by ultra-violet radiation. This field comprises the genetic alterations that form the basis of the process of cutaneous carcinogenesis. Actinic keratoses have the potential to be stable for years, to regress spontaneously or to become invasive carcinomas. There is a consensus in the literature that the treatment of the entire field cancerization is more effective than treating just isolated lesions since it is not possible to predict which of these lesions will evolve to invasive cancer. It is also effective in the prophylaxis and treatment of the existing clinically imperceptible incipient lesions. There are several therapeutic options for individualized actinic keratoses and the field cancerization, from self-applied topical drug therapies to interventional and surgical therapies.
Effects of Vitamin E, Vitamin C and Mannanoligosaccharide

Maintaining gut health is important for the production of high quality and profitable poultry. The goal of this study was to examine the effects of supplemental mannan oligosaccharide (Bio-MOS ), Vitamin E (VE) ® and C (VC) on the growth performance and immune response of broilers given a corn based diet over a 6 weeks experimental period. About 1 day old male broilers (n = 300) were randomly distributed to 4 groups (75 birds in each group and 15 birds in each subgroup for repetation 5 times) and reared under similar conditions. Standard husbandry and good management practices were followed that met or exceeded industry guideline. At each feeding, the following treatments were administered: control (no Bio-MOS , VE and VC), 1.5 g kgG Bio-MOS , ® 1 ® 500 μg kgG VE and 500 μg kgG VC. Body Weights (BW), Feed Intake (FI) and Feed Conversion Ratio (FCR) 1 1 were measured on day 1, 21 and 42. Blood samples were taken from vena ulnaris every 7 days and were analyzed on IgG concentration. The results showed that there was no significant difference in BW, FI and FCR among the treatment groups. During the 6 weeks of trial period considering plasma IgG levels significant differences were only found as following: compared to control group it was significantly lower in VE group at week 1 and 2, higher in VC and Bio-MOS groups at week 2 and lower in Bio-MOS group at week 6. Additionally, at 4 week ® ® lowest (0.90±0.06 mg, n = 15) and at 5 week highest (2.85±0.18 mg, n = 15) plasma IgG level was found after applying the dietary treatment in Bio-Mos group. Consequently, this data suggest that supplementation of ® Bio-MOS , VE or VC may not improve either broiler performance or immune response in healthy broilers. ®
The Influence of Web Distortion of Doubly- Symmetric Steel I-Beam on Elastic and Plastic Slenderness Limits

Lateral buckling of steel girders with slender webs and stocky flanges are accompanied by distortions in the web, known as lateral distortional buckling (LDB). These distortions result in reductions in the torsional and warping rigidities of the girders and cause them to buckle at moments below that calculated from lateral torsional buckling (LTB) formulations, neglecting the web distortions. Based on these considerations for estimating the LDB moments of doubly-symmetric steel I-beam in both elastic and inelastic ranges of buckling, the present study aims at developing elastic and plastic slenderness limits for the beam. These limits provide to use the right formula among the elastic and inelastic LDB equations. For this purpose, a numerical study was conducted to determine LDB moments of doublysymmetric steel I-beam for varying unbraced lengths. For all these works, the ABAQUS finite element program was utilized. In the finite element analysis, distributed loads were acted on flange of the beam, and roller supports was assigned to one end of the beam providing simple support conditions in and out of plane while for the other end pinned boundary conditions were defined. The present analyses indicated that the web distortions, which are usually accounted for in the inelastic range of lateral torsional buckling, also affect the buckling behavior of steel I-beams in the elastic range. The elastic and inelastic limiting unbraced lengths of steel beams were found not to comply with the buckling behavior in the presence of web distortions.
Foliar application of zinc, manganese, copper and boron influenced the fruit growth, development and quality of Khasi Mandarin (Citrus reticulata Blanco)

An experiment was conducted during 2016 and 2017 at Mizoram University, Aizawl, Mizoram to study role of micronutrients on fruit growth and development of Khasi Mandarin (Citrus reticulata Blanco). Randomized block design was adopted with sixteen treatments such as, Foliar application of T1: Zinc (Zn),T2:Manganese (Mn),T3: Copper (Cu), T4: Boron (B), T5: Zn + Mn,T6: Zn + Cu,T7: Zn + B,T8: Mn + Cu,T9: Mn + B,T10: Cu +B,T11: Zn + Mn + Cu,T12: Zn + Mn + B,T13: Zn + Cu + B,T14: Mn + Cu + B,T15: Zn + Mn + Cu + B,T16: Control (no micro nutrients). From the pooled analysis of two consecutive years during the experiment, foliar application of Zn+Cu+ B (T13) showed maximum fruit set percentage, maximum fruit yield, maximum number of fruits per tree, highest fruit retention percentage, highest ascorbic acid content, total sugar and minimum total fruit drop percentage, seed number per fruit and acidity percentage. Whereas, highest TSS and minimum seed weight and minimum peel weight were observed with treatment which received micronutrient combination of Zn + Mn + Cu+ B (T15) against control. However, maximum fruit weight was observed with application of Zn + Mn + B (T12) and maximum fruit juice content with foliar application of Zn + Mn + Cu (T11).
