title: Facile Methods for the Assembly of Large-Area Perovskite Solar Cells and Mini-Module: A Step-by-Step Description of Layers Processing

description: Hybrid organic-inorganic perovskites have attracted interest in photovoltaic applications due to their excellent optoelectronic properties and low-temperature processability. From 2009 to 2021, lab-scale perovskite solar cells (PSC) reached a power conversion efficiency (PCE) of 25.7%, and a PCE of 17.9% for perovskite solar modules with an area of 800 cm2. Here, we present an investigation using three deposition techniques, spin-coating, blade-coating, and spray-coating, to process the charge transport layers and the active layer of perovskite solar cells onto 5 cm × 5 cm sized substrates, with device structure glass/fluorine-doped tin oxide (FTO)/c-TiO2/meso-TiO2+Perovskite/2,2’,7,7’-tetrakis(N,N-di-p-methoxyphenyl-amine)9,9’-spirobifluorene (spiro-OMeTAD) or poly(3-hexylthiophene) (P3HT)/Au. Large-area PSC achieved an open-circuit voltage of around 1.1 V and PCE of 6%. The power generated was sufficient to start a fan. Furthermore, the connection in series of two large-area PSCs generated a voltage of 1.9 V. Then, we developed a simple method for manufacturing a monolithic perovskite mini-module containing two series-connected PSCs without using laser-scribing processes (usually named P1, P2, and P3 processes). This mini-module delivered a voltage of 1.52 V. Both voltages (1.9 and 1.52 V) were enough to turn on a red (or yellow) light-emitting diode (LED). To our knowledge, this is the first scientific report describing the assembly of a large-area n-i-p perovskite single cell and mini-module in Brazil.

title: Genetic gain for technological traits in new cultivars developed by the Southern Brazilian common-bean network

description: ABSTRACT Estimating the genetic gain obtained for technological quality traits over the years makes it possible to analyze whether the changes made meet consumer preferences, which represents an important innovation for common-bean breeding programs. The objectives of this study were to obtain genetic gain estimates for technological grain quality traits of common bean lines and investigate whether the modifications made were favorable in the context of sustainability and food and nutritional security for the coming generations. Twenty-four experiments were conducted between the years 2010 and 2022 and a total of 75 common bean lines were evaluated. Genetic gains of technological grain quality traits were determined by the Vencovsky’s (1988) method adapted for biennia. There was a significant effect of genotype for most traits evaluated, which shows the existence of genetic variability. Mass of 100 grains and water absorption had a negative genetic gain of -2.91% and -0.55% per year, respectively, indicating a reduction in these traits. Genetic gain was zero for L* value (lightness) and cooking time, denoting a plateau for these traits. Most of the common bean lines exhibit adequate L* values for carioca (L* ≥ 53) and black (L* ≤ 22) bean grains; a mass of 100 grains from 20 to 25 g; and fast cooking (≤ 25 min). The new common bean cultivars released for cultivation in the southern region of Brazil have high technological grain quality, being favorable in a context of sustainability and food and nutritional security for the coming generations.

title: Epidemiological profile and visual improvement after cataract surgery performed at a reference ophthalmological hospital in Santos

description: ABSTRACT Objective To identify the epidemiological profile and visual benefit of the patient using the Unified Health System after cataract surgery. Methods This is a descriptive, cross-sectional and retrospective study with the analysis of medical records, between October and November 2020. We included 573 eyes of 319 patients that were selected for cataract surgery. Gender, age, cataract classification, pre-and post-surgery corrected acuity, smoking, presence of comorbidities, and previous ocular alterations were analyzed. Results Of the cataract surgeries performed, the mean age was 70.5 years (±7.1%), with a prevalence of 57.1% (n=182) in women; 13.8% (n= 44) were smokers. Systemic arterial hypertension was the most recurrent comorbidity, present in 65.8% (n=210), and glaucoma was the most common ocular alteration in 57% (n=45) of the cases. As for cataract classification, nuclear cataract was manifested in 71.9% (n=412). Visual acuity was evaluated by the logMAR scale, and counting fingers and hand motion were given the value of 3. Mean visual acuity before surgery was 0.7 with an SD of 0.9 and, after surgery, of 0.1, with an SD of 0.3, which was statistically significant. Conclusion Knowledge of the epidemiological profile and visual benefit after cataract surgery allows us to identify risk groups and the importance of the procedure to improve the quality of life. Public actions must be implemented to increase the number of projects that aim to reduce the number of cataracts, since it is the main cause of reversible blindness in the world, interfering with the daily life of the population.

title: Investigation of the Relationship Between Triglycerides-Glucose İndex and Coronary Slow Flow: A Retrospective Case-Control Study

description: Abstract Background Coronary slow flow (CSF) refers to delayed distal vessel opacification in the absence of epicardial coronary artery stenosis. The etiopathogenic mechanism of CSF is still unclear. Objectives This study investigates the relationship between CSF and the triglyceride-glucose (TyG) index. Methods The study sample consisted of 118 CSF patients and 105 patients with normal coronary flow (NCF). The coronary flow rate was measured via the Thrombolysis in Myocardial Infarction (TIMI) frame count (TFC) method in all patients. The TyG index was calculated as the logarithm of the [fasting triglyceride (mg/dL)×fasting glucose (mg/dL)]/2 value. A significance level of &lt; 0.05 was adopted as statistically significant. Results The TyG index, low-density lipoprotein (LDL), body mass index (BMI), neutrophil-to-lymphocyte ratio (NLR) and TFC values, male ratio, and the ratio of smokers were higher, whereas high-density lipoprotein (HDL) levels were significantly lower in the CSF group compared to the NCF group (p&lt;0,05). The correlation analysis revealed that CSF was significantly correlated with TyG index, BMI, NLR, and HDL values. The strongest of these correlations was between CSF and TyG index (r= 0.57, p&lt;0.001). Additionally, the multivariate analysis revealed that TyG index, BMI, NLR ratio, and male gender were independent predictors for CSF (p&lt;0.05). Receiver operating characteristic (ROC) curve analysis indicated that a cut-off value of ≥ 9.28 for the TyG index predicted CSF with a sensitivity of 78% and a specificity of 78.1% [Area under the curve (AUC): 0.868 and 95% Confidence Interval (CI): 0.823-0.914]. Conclusion The findings of this study revealed a very strong relationship between CSF and TyG index.

title: Effects of chemical and green nano-zinc oxide on histological changes, oxidative stress, and apoptosis in rat kidney associated with cisplatin

description: Abstract Cisplatin (CP) is used to treat various tumors. A main restriction of cisplatin is nephrotoxicity. This study aimed to evaluate the protective effects of ZnONPs on cisplatin-induced oxidative stress and rat kidney tissue damage. Eighty adult male Wistar rats (250g-270g) were divided into ten groups: Control (CON), Sham (SH), Bulk ZnO (BZnO), Chemical ZnONPs (ChZnONPs), Green ZnONPs (GrZnONPs), Cisplatin (CP), Cisplatin+BulkZnO (CP+BZnO), Cisplatin+Green ZnONPs (CP+GrZnONPs), Cisplatin+Chemical ZnONPs (CP+ChZnONPs), Cisplatin+Explant (CP+EX). CP was i.p administered 5mg/kg/week and BZnO, ChZnONPs and GrZnONPs were i.p administered at a dose of 5mg/kg/day. After 30 days of the treatment, the expression of apoptosis/anti apoptosis related genes oxidant/antioxidant factors and histological changes in the were studied. The CP-treated group showed a decrease in body weight, while the Co-administration of ZGNPs to CP-treated rats showed a significant increase compared to the CP group. The results showed that the increased mRNA level of bax, MDA and the decreased mRNA level of bcl2, SOD and CAT activities in kidney of CP group were improved when animals were treated with ZnO NPs. Our results showed that GrZnONPs, ChZnONPs and BZnO had the potential to protect against oxidative stress and cisplatin-induced neurotoxicity that this protective effect was more evident in GrZnONPs.

title: First record of Cerchysiella insularis (Howard, 1897) (Hymenoptera: Encyrtidae) parasitizing Lobiopa insularis (Castelnau, 1840) (Coleoptera: Nitidulidae) on strawberries

description: ABSTRACT: Strawberry is one of the most socially and economically important small fruits in Brazil, with strong demand by the food industry driving high levels of production. However, phytosanitary problems, especially insect damage, can hamper strawberry cultivation. A pest of great concern is the strawberry sap beetle, Lobiopa insularis (Coleoptera: Nitidulidae), which damages the fruits. Chemical control has not been effective against L. insularis, as it makes harvesting and marketing the product unfeasible. Parasitoids have been effectively utilized to control various strawberry pests and support sustainable production. We report the occurrence of the wasp Cerchysiella insularis (Hymenoptera: Encyrtidae) as a parasite of L. insularis on strawberries in São José dos Pinhais, Paraná, Brazil. Samples of strawberries (San Andreas cultivar) attacked by L. insularis were collected from February to March, 2019. Lobiopa insularis larvae were individually placed in rearing pots, fed on San Andreas strawberries, and checked weekly for symptoms of parasitism or parasitoid emergence. Parasitism rates were 33.85% in March and 45.90% in February. The sex ratio varied between 0.88 and 0.86. All parasitized larvae were infested by C. insularis. The natural parasitism rate above 33% and high sex ratio of C. insularis in strawberry crops indicated that it may have the potential in the control of L. insularis.

title: Vernalization temperature and maturation point of seed cloves on garlic production and quality

description: ABSTRACT Brazilian producers have been seeking to improve garlic productivity and quality via vernalization at negative temperatures. However, more concrete information about the application and effects of this technique on the productivity and quality of noble garlic varieties is lacking. Moreover, there are also questions about the use and influence of seed cloves at different maturation points on this crop’s yield. Therefore, the objective of this work was to evaluate the effects of vernalization temperatures and different maturation points of seed cloves on the yield and quality of noble garlic cultivars. Three experiments were conducted using the Ito cultivar over three garlic planting seasons in Cristalina, GO, Brazil. The experimental design followed a 3 x 3 factorial scheme: three vernalization temperature ranges (-1 to -3 °C; 1 to 3 °C; and 2 to 4 °C) and three seed clove maturation points (normal, early and late). Plant height, aboveground fresh mass, bulbar ratio, and bulb yield and quality were evaluated after harvesting. The negative vernalization temperature had significant results with the highest garlic yields occurring in all three planting seasons, with a considerable increase in the quantity of bulbs with better commercial value (‘class 6’) and a decrease in the quantity of ‘discard’ bulbs. In comparison to the other temperatures, negative vernalization temperatures also yielded higher fresh plants in all evaluated seasons. The normal maturation point resulted in gains in total bulb yield. The use of below-zero vernalization temperatures increased the productivity of the garlic cultivar Ito under the conditions found in Brazil.

title: Regional integration, triangular trade and policy recommendations: the case of the Brazilian fine chemical industry

description: ABSTRACT This paper examines the occurrence of “triangular trade schemes” in the export of fine chemical products to Brazil from other Mercosur countries between 1989 and 1992 and suggests possible government counter measures. It is shown that the sudden increase in Brazilian imports of fine chemicals from Uruguay corresponds to a “triangular” trade scheme between both countries and a third party and suggests the adoption of more precise origin rules than those agreed during recent Mercosur negotiations, allowing the gains from integration to accrue mainly to the member countries.
