Anthracnose, caused by the fungal pathogen Colletotrichum orbiculare (Berk. & Mont.) Arx syn. lagenaria, is one of the most important diseases of watermelon in the United States and worldwide. The study was conducted to identify C. orbiculare race 1 resistance quantitative trait loci (QTL) in a ‘Charleston Gray’, resistant parent, and ‘New Hampshire Midget’, susceptible parent, biparental mapping population. The mapping population consisted of 228 F2 and the validation population consisted of 60 individuals each in BC1P1 and BC1P2. The disease severity was rated using a disease index comprising a rating scale of 0 to 100%. IciMapping was used to draw the linkage map and R/qtl non-parametric method (‘model = np’) was used to identity QTL. We identified a major disease resistance QTL, Qar1-8, on chromosome 8. The significant SNP marker S8_5149002, part of a putative coiled-coil (CC)–nucleotide-binding site (NBS)–leucine-rich repeat (LRR) (CC-NBS-LRR or CNL; ClCG08G002410), had a LOD of 14.06. The significant marker was validated on mapping populations using R package functions ‘chisq.test’, ‘wilcox.test’, ‘kruskal.test’, and ‘dunn.test’. The significant marker S8_5149002 was also tested for its ability to differentiate race 1 anthracnose resistance on 61 watermelon germplasm including 41 plant introduction (PI) lines. Hence, the diagnostic SNP marker S8_5149002 could be used for marker assisted selection (MAS) for race 1 anthracnose resistance in watermelon breeding programs.

Published: June 2022

Metal-organic framework materials(ZIF-9) were loaded on Sodium alginate/polyvinyl(PVA/SA) hydrogel by in situ growth method for adsorption of heavy metal Cu (II). The structure of hydrogels composited with MOFs and polymers was designed to improve the poor mechanical properties of natural polymer gel materials and the inconvenience of powdered MOFs materials in practical applications. The adsorption results showed that the optimum adsorption process of Cu (II) pH was 5.0. The adsorption kinetics and isotherm suggest that the adsorption process follows the Freundlich isotherm and the pseudo-second-order models. The experimental maximum adsorption capacity was 98.98 mg/g, 2.6 times and 1.5 times higher than ordinary SA and PVA/SA hydrogel spheres. Synthesized hydrogel spheres were characterized by FT-IR, SEM, XRD, and XPS, which confirmed that MOF materials have grown in situ on PVA/SA hydrogel spheres. More importantly, PVA/SA@ZIF-9 exhibited exceptional mechanical stability and showed excellent recycling capability in the cyclic adsorption process.
Understanding the reaction mechanism of the CO2 and cyclohexene oxide copolymerization catalyzed by zinc(II) and magnesium(II) catalysts: a DFT approach

Published: June 2022

The reaction mechanisms of carbon dioxide and cyclohexene oxide copolymerization catalyzed by four different zinc(II)-magnesium(II) catalysts were computationally studied using the density functional theory at the BP86-D3(BJ)/def2-TZVP/SMD//BP86-D3(BJ)/def2-SVP/SMD level of theory. The results showed that the most effective catalyst was the ZnMg system, in which poly(cyclohexene carbonate) was the preferred product, followed by the side product cis-cyclohexene carbonate. The QTAIM, NCI and ELF analysis performed to understand the role of metals in the reaction showed that ligands and substrates interact more strongly with zinc(II) centers compared to magnesium(II) centers. Furthermore, the Zn-I interaction at the M1 position was stronger than the Mg-I interaction at the same position. All these results indicate a synergism between the metals Zn and Mg, which makes Zn(II)Mg(II) the best combination for the reaction.
Low Latency Low Loss Media Delivery utilizing In-Network Packet Wash
Authors: Clayman Stuart , Sayıt Müge
Published: June 2022

This paper investigates how to carry streams of layered video using Scalable Video Coding (SVC) from servers to clients, utilizing the Packet Wash mechanism devised for the Big Packet Protocol (BPP). The mechanisms utilized are presented together with the video’s path through the network. BPP was designed to handle the transfer of packets for high-bandwidth, low-latency applications, aiming to overcome a number of issues current networks have with high precision services. One of the most important advantages of BPP is that it allows the dynamic adaption of packets during transmission. BPP is based on the idea of injecting meta-information into packets in order to provide programma-bility for network nodes on how to process those packets, and that given specific commands, a node can drop parts of the payload. The strategy BPP uses is to reduce the payload of a packet, and its size, by eliminating specific chunks. For video, this means cutting out specific segments of the transferred video, rather than dropping packets, or retrying the transmission of packets. This approach has proved to be an effective way to enhance the performance of video streaming applications, by obtaining continuous delivery, while maintaining guaranteed quality at the receiver. In this work we have successfully used an H264 Scalable Video Codec (SVC) encoded video for layered video transmission utilizing BPP, and can demonstrate video delivery with low latency and low loss in limited bandwidth environments.

OBJECTIVE To compare the inhibition of lymphocyte-activation gene 3 (LAG3) plus programmed cell death 1 (PD-1) versus the inhibition of cytotoxic T-lymphocyte antigen 4 (CTLA-4) plus PD-1 in patients with previously untreated advanced melanoma.DESIGN A meta-analysis of individual participant data (IPD).DATA SOURCES PubMed, Web of Science and Embase were searched from January 1, 2015, to January 14, 2022, for eligible studies.ELIGIBILITY CRITERIA FOR STUDY SELECTION Data from randomized controlled trials reporting on the use of dual LAG3-PD1 inhibitors or dual CTLA4-PD1 inhibitors which assigned PD1 inhibitor alone as their control arm and provided corresponding Kaplan-Meier (KM) curves of treatment outcomes for previously untreated advanced melanoma were retrieved. METHODS The IPD data were extracted from the KM plots using a graphical reconstructive algorithm. Log-rank, Cox proportional hazard model, Bayesian hierarchical model with time-varying hazard ratio (HR) effect, and restricted mean survival time (RMST) were performed to estimate survival benefits. The primary endpoint was progression-free survival.RESULTS The CheckMate-067 (N = 630) and RELATIVITY-047 (N = 714) trials were included for analysis. The graphical reconstructive algorithm showed that IPD had similar HRs and log-rank values as the original plots. The HR of nivolumab-relatlimab (LAG3 inhibitor) versus nivolumab-ipilimumab (CTLA4 inhibitor) was 1.19 (95% confidence interval [CI] 0.96 to1.48). The 24-months RMST of nivolumab-relatlimab versus nivolumab alone was 2.35 (95% CI 0.77 to 3.94) months, compared with 1.87 (95% CI 0.25-3.49) months for nivolumab-ipilimumab versus nivolumab. The Bayesian hierarchical model showed that patients treated with nivolumab-relatlimab had earlier PFS benefits than those with nivolumab-ipilimumab. Grade 3 or 4 treatment-related adverse events occurred in 18.9% of patients using nivolumab-relatlimab and 55.0% of patients using nivolumab-ipilimumab.CONCLUSION These findings suggest that the PFS of LAG3-PD1 and CTLA4-PD1 inhibition were similar and that LAG3-PD1 inhibition tended to exhibit earlier survival benefit and lesser TRAEs.
A multi-wavelength observations on the infrared dust bubble N75
Authors: Cui Quanling , Zhang Chuan-Peng , Wang Jun-Jie
Published: June 2022

We presented a study on the infrared dust bubble N75 using the IRAM 30m telescope at Spain and searched for star formation evidence in its surroundings. We observed C18O, HCO+, HNC, N2H+ towards N75 and performed a multiwavelength study around G38.93 with data taken from large-scale surveys: GLIMPSE, MIPSGAL, GRS, NVSS and BGPS. We analyzed the spectral profifile and the distribution of the molecular gas and dust in the G38.93. Morphologically, the C18O emission correlates well with Spitzer IRAC 8.0µm emission. The channel map and the velocity-position diagram show that the outflflow exists in G38.93. We calculated the physical parameters of the outflflow including the mass, size, column density and optical depth. We found only several YSOs coincident with the bright bubble rims. It is possible that YSOs have not yet formed, or will not be, formed in the bubbles shells, or they are simply hidden amid the high IR background. The dynamical age (∼ 5.1×105 yr) of outflflow is close to the expanding age (∼ 2.5 × 105 yr) of the bubble. It could be that the both are formed at the same evolutionary period.
Kernel Method for Estimating Matusita Overlapping Coefficient Using Numerical Approximations
Authors: Omar  , Enas
Published: June 2022

In this paper, the nonparametric kernel method is used to estimate the well known overlapping coefficient known as Matusita 𝜌. Due to the complexity of finding the formula expression of this coefficient when using the kernel estimators, we suggest to use the numerical integration method to approximate its integral as a first step. Then the kernel estimators were combined with the new approximation to formulate the proposed estimators. Two numerical integration rules known as trapezoidal and Simpson rules were used to approximate the interesting integral. The proposed technique produced two new estimators for 𝜌. The proposed estimators are studied and compared with existing estimator developed by Eidous and Al-Talafheh (2020) via Monte-Carlo simulation technique. The simulation results clearly demonstrated the usefulness and efficiency of the new technique for estimating 𝜌.

Authors: Aboul-Ella Hassan , Hamed Rafik , Abo-Elyazeed Heidy
Published: June 2022

Dermatophytosis is a widely spread contagious zoonotic disease, affecting both man (tinea) and animals (ringworm). This disease is caused by a group of closely related keratinophilic fungi known collectively as the dermatophytes group. Although the wide distribution of dermatophytosis cases throughout the whole world and its adverse clinical effect on human health, economical effect on productive animals, and pet animal welfare, there is no rapid accurate diagnostic tool for such disease. Up to date, dermatophytosis diagnosis is limited to direct, rapid with low sensitivity and specificity several wet mounts techniques, sophisticated with high skilled personnel requirement molecular assays, and gold standard with long time consumption conventional culturing and biochemical testing. All of the previously mentioned existing diagnostic methods are lab confined techniques with no availability of a field, handheld, or bedside tests. The different aspects of difficulties facing dermatophytosis diagnosis lead to mistaken diagnosis and faulty prescription of antifungals with its expected long list of side effects on man and animals. The current conducted study tries to accomplish the difficult equation by achieving an accurate, sensitive, specific, user-friendly, rapid, robust, device less, deliverable to end-users, and economic cost for development and production diagnostic kit. The newly designated and developed kit, based on lateral flow immune-chromatographic assay, showed a very promising competitive diagnostic result.

Published: June 2022

Crystalline silicon (c-Si) has been widely used in semiconductor and energy-related industries. One of the biggest challenges of c-Si production is its high energy and environmental cost due to the requirement of high-temperature synthetic process and the accompanied intense greenhouse gas emission. Herein, we demonstrate a new process for preparing c-Si directly from hydride-terminated silicane (HSi) under mild conditions. We design a wet-chemistry approach that effectively creates Si-Si bonds between HSi flakes via nucleophilic attack by Lewis base reagent at room temperature. c-Si produced by such a chemical suturing process demonstrates promising capability in charge carrier migration and separation under visible light irradiation, which is of critical importance in photocatalysis. Compared to the existent c-Si manufacturing processes, the reported approach drastically reduces the energy consumption and provides a new strategy to tailor the electronic and photophysical properties of c-Si for optoelectronic and catalytic applications.
Predictive Analytics for Cold Chain Break Detection
Authors: Kale Swati Dilip
Published: June 2022

Perishable food deteriorates at any step in the cold chain due to various internal and external factors. The leading cause of deterioration is fluctuating ambient temperatures. An intelligent cold chain management system comprises proper observation and control of perishable food parameters from food safety. The current work develops a predictive model that considers critical factors like vehicle characteristics, initial and environmental temperature, method of loading and unloading the food in-vehicle, and measurement of Mean Kinetic Temperature (MKT). Predictive data analytics is carried out using machine learning algorithms for real-time forecasting of food quality at each stage of the cold chain. Machine learning models are a step forward in cold chain management that is more accurate and requires less computing time than traditional techniques such as CFD (Computational Fluid Dynamics) method, Kriging method, and capacitive heat transfer method. Thus, the developed system will avoid cold chain breakage caused by temperature abuse during transit. Experimentation with various perishable foods is being considered. The results are experimentally validated in real-time applications.

Published: June 2022

Ready-to-eat (RTE) salads service and utilize with pide/lahmacun, kebab types, and tantuni in meat restaurants in Turkish cuisine. Hence, the vegetable salads served with meat-based RTE foods are a risk factor for public health. In this study, we report the microbiological properties, antimicrobial resistance of foodborne pathogens including E. coli and S. aureus, and the presence of important enteric viruses in eastern Turkey. The total aerobic bacteria (TAB) ranged from < 1 to 6.40 log CFU g− 1 in the RTE salads (n = 42), whereas yeast and molds was ranged from < 1 to 6.26 log CFU g− 1. The coliform bacteria and the Staphylococcus and Micrococcus spp. count were determined < 1-5.82 log CFU g− 1 and < 1-5.66 log CFU g− 1 in all REVS samples, respectively. None of the RTE vegetable salads (REVS) tested in this study contained Salmonella spp., whereas E. coli and S. aureus were isolated in 38.1% (16/42) and 2.4% (1/42), respectively. S. aureus was resistant to gentamicin, kanamycin, aztreonam, and ciprofloxacin in the disc diffusion assay, however, it was not harboring the mecA gene. E. coli strains (n = 16) were resistant (100%) to aminoglycoside antibiotics (gentamicin and kanamycin) and 35.7% (6/16) of the isolates were ESBL producing. BlaTEM and blaCTXM8/25 were detected in two isolates, whereas one isolate carried blaCTXM−1 and blaTEM together by PCR. Of the REVS, two were evaluated as positive for rotavirus (4.8%), and six for hepatitis A (14.3%) and hepatitis E virus (14.3%). These results indicate the high microorganism load, presence of ESBL E. coli, and viral enteric pathogens in REVS, hence it is important to perform routine hygiene practices.

Shiga toxigenic strains of E. coli (STEC) known to be etiological agents for diarrhea were screened for their incidence/ occurrence in selected abattoirs and retail meat sources in Osogbo metropolis of Osun State, Nigeria using a randomized block design. Samples were plated directly on selective and differential media and confirmed serologically using latex agglutination serotyping kit, then, multiplex PCR analysis was used to screen for the presence of specific virulence factors. The results showed a percent occurrence of STEC at the sampled sites ranging from 25.8- 46.3%. None of the strains showed any visible agglutination with the O157 latex reagent. Sequence analysis of PCR products was performed on a representative isolate showing the highest combination of virulence genes. This sequence was subsequently submitted to GenBank with accession number MW463885. The sequence showed 100% coverage and 96.46% percentage identity with Escherichia coli O113:H21 (GenBank Accession number: CP031892.1) strain from Canada. From evolutionary analyses, the strain from Nigeria, sequenced in this study, is evolutionarily distant when compared with the publicly available sequences from Nigeria. Although no case of E. coli O157 was found within the study area, percent occurrence of non-O157 STEC as high as 46.3% at some of the sampled sites is worrisome and requires regulatory interventions in ensuring hygienic practices at the abattoirs within the study area.

Identification of Key Sectors in Nigeria – Evidence of Backward and Forward Linkages from Input-Output Analysis
Authors: Ojaleye Dayo , Narayanan Badri
Published: June 2022

The input-output table provides summary information on the industrial structure of an economy in a specific period. This table contains information on the flow of goods and services between industries and economic sectors. The backward and forward links are descriptive measures of the economic interdependence of sectors in terms of the volume of transactions. Sectors with strong backwards and forward linkages are vital sectors and play an essential role in a country’s development strategy. This paper aims to construct a symmetric input-output table for Nigeria and examine the Nigerian economy’s production structure by using the results applying traditional backward and forward linkage methods developed by Chenery-Watanabe and Rasmussen. Our study identifies the key sectors with backward and forward linkages as Crop and Animal production, Manufacture of Food products, Textiles, Refined petroleum products, Chemicals, Motor vehicles, Furniture, Machinery and equipment, Wholesale/retail trade, Land transport and Telecommunication. In addition, through the constructed symmetric input-output table, sector development can be further done in line with the relationship matrix, as it serves as a conduit for investment strategy, local linkage matrix and policy development. So, for the development strategy it is very important to determine which industries possess high backward and forward linkages, then stimulating final demand or primary inputs namely of these industries could positively influence the economic activity of the country. The results from this work may be used by policy makers in terms of which sectors of the economy stimulate (for example, by means of creating extra final demand, decreasing taxes, or with the help of subsiding) in order to gain better results in the sphere of economic development of Nigeria.
Autentificar, falsificar y patrimonializar. La cerámica Alzate y la transformación de su valoración
Authors: López Lugo Iván Darío
Published: June 2022

El caso de la cerámica Alzate es un reconocido episodio en el que un grupo de expertos locales y algunos científicos europeos fueron engañados por parte de una familia de la ciudad de Medellín a principios del siglo XX, conocida como los Alzate quienes fabricaban cerámicas de barro con fines comerciales, las cuales fueron a parar a algunos de los museos más importantes en el mundo como el Museo de Historia Natural de New York, el museo Trocadero en Francia, el Museo de Neuchâtel en Suiza, entre otras instituciones, como precolombinos originales. Este particular hecho configura un capítulo sin precedentes en cuanto a la valoración del patrimonio cultural precolombino se refiere, la reinterpretación de este por parte de unos artesanos locales y la comercialización del pasado material de los indígenas que dieron origen a una expresión artística local basada en modelos indigenistas del pasado. De otra parte, es un episodio como pocos en los que un objeto pasa de ser considerado como una evidencia material invaluable de las culturas americanas de antes de la conquista, a ser consideradas como falsificaciones de poco valor para ser consideradas posteriormente como piezas importantes por su estética y carga cultural siendo actualmente custodiadas por varias instituciones museísticas en Colombia y el mundo.
El ocultamiento del símbolo y la imaginación: repercusiones en el sistema educativo actual

Published: June 2022

En el presente trabajo teórico-reflexivo se abordan las nociones del símbolo y la imaginación como facultades cardinales para el desarrollo individual y social del ser humano. Se acentúa el interés en la concatenación de ambas nociones para construir sociedad y el ocultamiento que éstas han experimentado desde el auge del pensamiento racionalista y positivista. Además, se aborda la consecuencia de esta desestimación de lo simbólico y la imaginación en el actual sistema educativo formal. En este artículo se advierte que la situación por la que atraviesan los modelos educativos y la forma de enseñanza que reproducen, responden a los propósitos del mercado financiero, la tecnociencia y la atomización de los saberes, que se nutren de un pensamiento de racionalidad científica-tecnológica. Lo anterior en desmedro de los saberes humanistas que, por su naturaleza reflexiva y teórica, potencian el desarrollo de las capacidades simbólicas e imaginativas.
Price reaction to rights issue announcements of family firms
Authors: Setia-Atmaja Lukas , Suthiono Henry
Published: June 2022

This study examines the effect of family control on the price reaction to rights issue announcements of publicly listed firms in Indonesia during the period of 2005–2018. The study uses agency theory, which discusses the conflict of interest between controlling/majority and non-controlling/minority shareholders. The results show that the price reaction to the right issue announcements for publicly listed firms in Indonesia is statistically significantly negative. The mean of cumulative abnormal returns (CAR) falls between –1.40% (for the Day 0 window period) and –3,43% (for the –5 to +5 window period). Further examination indicates that family control is associated with a more negative price reaction to these rights issue announcements. Specifically, for rights issue announcements of family firms, the mean cumulative abnormal returns (CAR) fall between –1,98% at announcement day (Day 0) and –5,23% for the event window period (–5 to +5). Meanwhile, for rights issue announcements of non-family firms, the current study found statistically insignificant price reactions to rights issue announcements for all the event window periods. These findings suggest that investors perceive higher agency problems among family firms where the family controlling shareholders tend to misuse and tunnel the rights issue funds for their own private benefit.

Published: June 2022

Foot-and-mouth disease (FMD) is an acute, febrile and highly contagious disease caused by foot-and-mouth disease virus (FMDV), mainly affecting cloven-hoofed animals. FMDV antibody detection can provide a timely understanding of the immune level after vaccination. In this study, 22,902 cattle blood samples from free-range households and large-scale farms were collected from eight districts in Tongliao city, Inner Mongolia Autonomous Region, China, from January to December 2020. Serum antibodies against serotypes O and A FMDV were detected by liquid-phase blocking ELISA. The results showed that the positive rates of serotypes O and A FMDV antibodies in Tongliao were 91.21% and 90.18%, respectively. The positive rates of serotypes O and A FMDV antibodies in 8 regions ranged from 85.80% to 98.41% and 84.48% to 96.77%, respectively. The positive rates of serotypes O antibodies in cattle from households and farms were 82.15% to 97.41%, and 90.51% to 99.32%, respectively. The positive rates of serotypes A FMDV antibodies in cattle from households and farms ranged from 83.47% to 96.77% and 84.98% to 97.30%, respectively. The positive rates of serotype O FMDV antibody in spring, summer, autumn and winter were 92.68%, 94.40%, 88.84% and 84.32%, respectively, and those of serotype A FMDV antibody were 93.50%, 92.19%, 87.26% and 88.86%, respectively. The results indicated that the immunization level of FMD was high in Tongliao city, and all positive rates exceeded the requirement that the qualified rate of immune antibody should be kept above 70% all year long according to the National Compulsory Immunization Plan of Animal Epidemic Diseases in 2020. However, vaccination and antibody detection of cattle raised by households in autumn and winter should be strengthened. The results of this study can provide a basis for authorities to formulate FMD prevention and control plans.

The topicality of researching specific features of migration processes on the territory of the Russian Federation deals with the rising role of economic security in providing strategic priorities of states in the period of growing tension in the world. Apart from that, such factors as unfavorable demographic situation, changes in the age structure of the population, adverse trends on labour market of many regions, shortage of labour, etc. become more and more important. It increases academic and practical interest in researching migration processes on different territorial levels, including the sphere of national and economic security. The Decree of the President of the Russian Federation N 208 dated May 13, 2017 ‘Concerning Strategy of Economic Security in the Russian Federation for the Period up to 2030’ defined optimization of labour migration flows based on needs of national economy as one of key objectives of realizing the trend dealing with the development of state governance system, forecasting and strategic planning in economy.  This document among indicators characterizing economic security focuses on the tension factor on labour market, the share of employable people in the total population and distribution of those employed by the level of education. The Degree of the President of the Russian Federation N 400 dated July 2, 2021 ‘Concerning Strategy of National Security of the Russian Federation’ points out that attaining goals of economic security of the Russian Federation is realized by solution of such important problems as cutting differentiation of entities of the Russian Federation by the level and rate of social and economic development, standard of living, motivating the development of economic potential in regions, strengthening of their budget support. Migration processes are included in the zone of such problem solution. They can cause even higher territorial differentiation in regions, a drop in the standard of life or, on the contrary, reduce territorial inequality and improve space development of the country. In view of national and economic security external migration is more important, as it influences many social and economic aspects taking place in the country. But whether migration processes inside the country can affect economic security of Russia is still a debatable issue.

Published: June 2022

The article studies factors affecting the efficiency of interaction between small business and higher education, tools of interaction between business and higher education and identifies problems of non-coordination of business and higher education. The necessity to upgrade infrastructural support of business and higher education interaction was substantiated. The current practices of business and higher education were investigated, which gave an opportunity to come to the conclusion about inefficiency of these ties. Misbalance of labour market, absence of demand for graduates of higher education on regional market and consequently, outflow of young highly-qualified workers show the need to upgrade ways of interaction between business and higher education and to develop the adequate infrastructure. The author grounds the necessity to raise professional competences of business in order to build foundation for the development of innovative forms of entrepreneurship and involvement of young qualified personnel with higher education in their work. Analysis of business and education interaction allows us to improve efficiency of interaction between business and higher education by setting-up the education cluster. Within the frames of the education cluster creating investment appeal of higher education is created.

A principal forma de propagação de Schinus terebinthifolius é por sementes, contudo pouco se conhece sobre os testes para a avaliação da qualidade fisiológica das sementes dessa espécie. Os objetivos do presente trabalho foram avaliar a influência da temperatura no teste de germinação em sementes de S. terebinthifolius e verificar a eficiência do teste de condutividade elétrica. Sementes de três lotes foram submetidas a teste de germinação nas temperaturas de 20ºC e 25ºC e a testes de vigor: índice de velocidade de germinação, tempo médio de germinação, comprimento de plântula e condutividade elétrica, com leituras após 0, 2, 4, 6, 8, 10, 12, 24, 26 e 28 horas de embebição. Obtiveram-se plântulas mais vigorosas e resultados superiores para o índice de velocidade de germinação, tempo médio de germinação e comprimento de plântulas na temperatura de 25ºC. No teste de condutividade elétrica, após 10 horas de embebição, as leituras foram estabilizadas e permitiram a comparação entre lotes. A temperatura de 25ºC é mais adequada para a condução do teste de germinação de sementes de S. terebinthifolius, e o teste de condutividade elétrica não é recomendado para a análise da qualidade fisiológica das sementes de tal espécie.

O objetivo desta pesquisa foi comparar o tempo de permanência nas classes de conforto térmico que as ruas com e sem arborização proporcionam na cidade de Curitiba (PR). Para isso foram selecionadas três amostras, cada uma contendo um trecho de rua com e outro sem arborização; as ruas arborizadas eram compostas por diferentes espécies. Realizou-se o monitoramento das variáveis meteorológicas com miniestações da marca Kestrel® e “medidores de stress térmico” modelo TGD-400. A coleta desses dados ocorreu das 9 às 15 horas, com intervalo de monitoramento de 1 minuto, repetida nas quatro estações do ano, com início no inverno de 2011. O índice utilizado para a análise do conforto térmico foi o Universal Thermal Climate Index (UTCI). Os resultados demonstram que as ruas arborizadas, além de apresentarem melhores índices de conforto térmico do que as ruas sem arborização, proporcionaram condições de conforto por mais tempo. No inverno, as ruas arborizadas registraram conforto térmico em 92,6% do tempo; as ruas sem arborização, em 77,3%. No verão, as ruas arborizadas apresentaram conforto térmico em apenas 16,3% do tempo, enquanto as ruas sem arborização não evidenciaram conforto térmico em nenhum momento. Conclui-se que uma rua arborizada proporciona condições de conforto térmico por mais tempo do que uma sem arborização.

Dicksonia sellowiana is the only Brazilian tree fern in the Dicksoniaceae family. Due to the exploitation of its caudex for the manufacture of pots for plants, the species is endangered. The objective of this research was to analyze the spatial distribution of D. sellowiana in the araucaria forest. To obtain data, 37 sample units with 10 × 50 m each were evaluated and systematically distributed in 25-hectar permanent plots installed in the Irati National Forest. All tree ferns above 1.30 m in total height were identified and measured. To analyze the spatial distribution, three aggregation indices were used, while the total volume and the commercial volume were estimated using volumetric models. The density and population structure in height classes were calculated. The species has an average density of 83 individuals per hectare. Through the evaluation of the indices, it was verified that the species has an aggregated pattern. The estimates were 19.87 m3 .ha-1 for total volume and 11.82 m3 ha-1 for commercial volume, with more than 60% of these volumes concentrated in heights of 3.30 m to 6.30 m, which is about 40% of the population.

O objetivo deste estudo foi avaliar altas diluições dinamizadas de sulfato de ferro e fosfato natural sobre a incidência de tripes e os danos causados por eles, a severidade de míldio e a produtividade e o rendimento pós-colheita de cebola em sistema orgânico. Substâncias compostas de ferro e fósforo foram selecionadas pelo princípio homeopático da semelhança, pois podem favorecer a incidência de tripes. Conduziram-se dois experimentos individuais com altas diluições de sulfato de ferro e fosfato natural em 2016 e 2017, na Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri), na Estação Experimental de Ituporanga (SC). Os tratamentos consistiram em pulverizações foliares de altas diluições a 0,5% de sulfato de ferro e fosfato natural nas diluições 6CH, 12CH, 30CH e testemunha sem aplicação. A incidência e os danos de tripes, a severidade de míldio e a área foliar lesionada por ele e a produtividade e o rendimento pós-colheita não foram influenciados pelos tratamentos. Exceto em 2017, ano com menor precipitação pluviométrica, altas diluições de sulfato de ferro 6CH e 12CH reduziram a porcentagem de bulbos comerciais.

O uso empírico e indiscriminado de plantas medicinais para tratamento de doenças pode acarretar graves consequências à saúde humana. Apesar dos novos métodos disponíveis pelas indústrias de medicamentos, grande parte da população ainda utiliza as plantas medicinais em razão das tradições e dos hábitos de gerações e comunidades, o que torna necessários o conhecimento e o estudo das características e da preparação dessas plantas. As folhas das espécies Myrciaria floribunda e Eugenia uniflora, popularmente conhecidas como cambuizeiro e pitangueira, da família das mirtáceas, destacam-se pelas propriedades de uso medicinal. O presente trabalho teve como objetivo analisar o potencial mutagênico de M. floribunda e E. uniflora, por meio do teste de Allium cepa. Foram realizados quatro tratamentos com quatro repetições cada um, por meio de infusão de folhas frescas de cambuizeiro e pitangueira: (C-) água destilada (controle negativo); (C+) paracetamol 800 mg L-1 (controle positivo); (C1) 150 mg L-1; e (C2) 300 mg L-1. Os dados foram tratados pelo software SAEG 9.1. Os resultados obtidos apresentaram diferença significativa pelo teste de Scott-Knott (p ≤ 0,05). Verificou-se que, para M. floribunda e para E. uniflora, nas concentrações testadas, houve diferença em relação ao controle positivo, sendo este o que apresentou maior média (13,6 e 13,5, respectivamente). Esse dado possibilita o consumo, em função da baixa mutagenicidade evidenciada.

O conhecimento da ordenação das espécies ao longo de um gradiente altitudinal é importante para se conhecer sua distribuição, sobretudo em biomas ameaçados como a mata atlântica. O presente estudo foi realizado na reserva particular do patrimônio natural (RPPN) Alto Montana, localizada no município de Itamonte, na Serra da Mantiqueira, Minas Gerais, sudeste do Brasil. Analisou-se a influência do gradiente altitudinal na riqueza e na composição de espécies de vespas sociais. O método de amostragem foi busca ativa com rede entomológica e armadilhas atrativas, em nove pontos amostrais, distando 100 m um do outro. O gradiente estudado variou do ponto fixado a 1.335 até 2.135 m de altitude. Foram amostradas 11 espécies de vespas sociais, distribuídas em sete gêneros. Como esperado, houve correlação negativa significativa entre a altitude e a riqueza de espécies. Polybia punctata e Polybia fastidiosuscula foram as únicas espécies registradas nos pontos de maior altitude, estando também presentes em 78 e 66% dos pontos amostrais, respectivamente. Agelaia multipicta também se destacou por estar presente em 66% dos pontos. Para corroborar os resultados aqui obtidos, é necessário realizar mais estudos de longo prazo na área.

As pesquisas com sementes de espécies florestais vêm ganhando espaço em âmbito nacional em virtude da grande demanda de mudas para a preservação da biodiversidade, implantação de programas de recuperação de áreas degradadas e reflorestamento. Por isso, é necessário o conhecimento das melhores condições para o armazenamento, o que permitirá a oferta de sementes viáveis por um período mais longo de tempo, mesmo fora da época de frutificação dessas espécies. Diante disso, o objetivo do presente trabalho foi avaliar diferentes ambientes e o período de armazenamento de sementes de C. americana. As sementes, após a coleta, foram armazenadas em três locais – ambiente sem controle, câmara seca e geladeira – e avaliadas quanto à sua qualidade fisiológica em oito períodos (0, 2, 4, 6, 8, 10, 12, 14 meses) durante o armazenamento. As variáveis analisadas foram: grau de umidade das sementes, plântulas normais e plântulas anormais. As sementes de C. americana podem ser armazenadas em geladeira e em câmara seca sem afetar sua qualidade fisiológica por 14 meses.

A cidade de Joinville possui uma enorme capacidade para o desenvolvimento do turismo que vem crescendo, estando essa atividade de certo modo correlacionada com o clima, visto que, em dias de sol, os turistas aproveitam mais as atrações que a cidade oferece ao ar livre. Entretanto as emissões industriais da cidade estão entre as maiores causadoras do efeito estufa, que leva a mudanças climáticas e, consequentemente, afeta a vida na Terra. Posto isso, o presente trabalho tem como objetivo avaliar os padrões das emissões atuais e compará-los ao emprego de energia de fontes renováveis pelos maiores emissores. Foram realizados estudo de revisão bibliográfica na plataforma Google Acadêmico, acesso virtual a dados da concessionária de distribuição de energia elétrica de Santa Catarina e consulta à literatura científica. Após o levantamento bibliográfico e a análise dos gráficos, discutiu-se acerca do crescimento da cidade vinculado à expansão econômico[1]industrial para além do setor eletro-metal-mecânico. Na sequência, projetou[1]se o reconhecimento de uma cidade capaz de expandir tecnologias e projetos de desenvolvimento sustentável e ser exemplo, pelo emprego de energias de fontes renováveis.
