Authors: FESENKO O. O.
Published: February 2019

The article analyzes one of the opportunities for the enhancement of the efficiency of grain processing production - improvement of working conditions through the certification of the workplaces. Such action is the component of the sectorial program for development of a safety status, occupational health and the production environment, which is the task of each sectoral ministry. The grain processing branch of the agroindustrial complex demonstrates continuous and stable growth over the past decades. It creates additional workplaces, provides employment of the population, and preserves the labor resources of the country. However, the leading branch of agroindustrial complex has no sectorial program for improvement of safety status at the workplaces. As a result, the agroindustrial complex is the third largest in work-related incidents for last years. The reasons and circumstances of incidents are stated. The improvement of the situation is the certification of workplaces, which exercises the worker’s right to healthy and safe working conditions, benefits and compensation for work in adverse working conditions. The legal and regulatory framework for certification of workplaces, the composition of the certification committee, and the procedure for certification are given. The certification identifies the workplaces with the adverse working conditions, where it is necessary to take the first-priority measures for their improvement; the workplaces, production, jobs, professions and positions, for the employees of which it is proposed to establish benefits and compensations at the expense of the enterprise; confirms the right of employees to benefits and compensations stipulated by the legislation. The article deals with the adaptation of the European approach to the organization of monitoring of the influence of production factors on the safety and health of the person, which serves as the basis of new methodological recommendations for the certification of workplaces for working conditions. The list of jobs with heavy, harmful and dangerous work conditions at the grain processing enterprises is offered. The mistakes and disadvantages in the course of certification are stated. The employees of the food industry and agricultural processing sustain the occupational injuries due to labor process factors such as the severity and intensity of labor. In most cases, the causes of accidents (up to 80%) have organizationalarrangement nature, including failure to certificate the non workplaces for working conditions (or violation of the legislation on the certification of workplaces).

Published: February 2019

Functional properties of food products with the addition of germinated grain raw materials have become the object of increased attention of scientists and specialists in the food industry. In addition to the nutritional ingredients, food products with the addition of grain raw materials contain functional ingredients that positively affect the human body that helps to adapt to the effects of the external environment. Functional products with the addition of germinated grain are considered not only as a source of plastic substances and energy but also as a nutritional complex that provides a healing effect. The usage of germinated grain in the food and processing industries is very limited due to its short shelf life and the characteristics of preparing malt for further processing. A relevant technological challenge is the selection of barley malt moisture regimes. The cycle of researches concerning hydrothermal processing of dry barley malt has been carried out. The purpose of determining the optimal technological regimes of hydrothermal processing of dry germinated grain is the prospects for its further use in various food technologies as a food additive or a component of the enrichment of products with biologically active substances. The work highlights the selection process and the main technological parameters of the process that can be used in the industrial processing of barley malt. As a research object, dry germinated grain (malt) produced by a special technology was used. In the course of research, an optimal hydro module was selected for humidifying barley malt, the temperature regime of hydrothermal processing of germinated grain was determined, the degree of swelling of malted grain was determined, the optimum time of wetting of raw materials for its further processing was determined. When analyzing the data obtained, it was concluded that the optimal hydro module for swelling barley malt is 1:4, the optimum temperature is +65С and the duration of hydrothermal processing is 48 hours. The regimes of hydrothermal processing of barley malt presented in the article will allow optimizing the technological process of malt processing.

Published: February 2019

The development of new physiologically functional food products is a prospective direction for world food products market. The inclusion of functional ingredients in food can increase the biological value of products that are already familiar to the consumer, as well as expand the range of products offered. Physiological activity of cereal’s ingredients varies widely, there are: anticancer, antiallergic, antioxidant properties, prebiotic, immunostimulating effects, etc. Moreover, the cereal’s ingredients can improve the organoleptic properties of bakery, dairy and confectionery. Cereals can be used as a prebiotics: fermentable substrates for the growth of probiotic microbiota. It is scientifically proven that grain’s nondigestible carbohydrates stimulate the growth of Lactobacillus acidophilus, L. casei, L. reuteri, L. rhamnosus, L. johnsonii, L. plantarum, Bifidobacterium longum, B. breve, B. lactis. Cereals contain water-soluble fibre, such as β-glucan and arabinoxylan, oilgosaccharides, such as xylo- and fructooligosaccharides and resistant starch, which have a wide application as prebiotic preparations. Furthermore, cereals as wheat, rye and rice contain polyphenols (benzoic and cinnamic acid derivatives) that are used both in the food industry as antioxidants, dyes, flavors of natural origin and in the compositions of physiologically functional ingredients, as well as in the pharmaceutical and cosmetic industries. Thus using cereals as a raw material for functional ingredients obtaining is a perspective in biotechnology, food and pharmaceutical industry. The modification of cereals processing technologies also will allow produce insufficiently studied prebiotic compounds, the functionality of which must be studied.

Published: February 2019

The high efficiency of poultry and pigs is based on high-yielding breeds, balanced high-yielding mixed fodders and appropriate animal holding conditions. Recently, the tendency of increasing the efficiency of the nutritional potential of mixed fodder has become of increasing importance in order to reduce the cost of this factor in the production of livestock products. The role of the intermediate link between animals and the nutritional potential of feed is borne by enzymes. A few years ago the question about the use of exogenous enzyme preparations in the composition of feed was controversial. But a better understanding of the action of industrial enzymes, as well as more successfully developed enzyme preparations have changed the situation. Enzymes are now widely used in many countries around the world to improve the quality of feed produced on the basis of barley, wheat, wheat and barley, as well as other cereals. Perspective is the use of enzyme preparations in ration of young pigs in fattening. In our experiments, lysozyme was used to improve the productivity of young pigs. The experiments were carried out at "Iziumsky compound feed plant", Izium district, Kharkiv region and at the farm "Avangard-D" Ltd., Ovidiopolsky district, Odesa region. It was established that feeding of young pigs of mixed fodder enriched with the enzyme preparation "Lysozyme" prevents the growth of average daily increments, live weight of animals and reduction of feed costs per unit of products. The lowest feed costs per unit gain of live weight were set in the experimental group, which comprised 4.2 feeds. unit. That is less in comparison with animals of control group I by 7.0%. The economic efficiency of raising the young from 4 to 8 months of age has shown that the addition of prezime "lysozyme" to the diet of pigs affects the formation of basic expenses and the receipt of net profit per 1 head.

CLARIFICATION OF THE METHODS USED FOR CALCULATING POWER OF SIEVE SEPARATORS
Authors: SOLDATENKO L. S. , HORNISHNYI O. V.
Published: February 2019

Calculation of sieve separators power is usually done during their development. The goal of such calculations is to determine the power of driven electric motors. The imperfection of existing methods for calculating power of some types of sieve separators makes developers to use indicative methods to determine the gear power. For example, it is done using the method of specific energy consumption or the comparison method with parameters of similar equipment. These methods provide only indicative results, that is why the power of the installed electric motors sometimes even exceeds the needed one, so in such way it worsens technical and economic factors of the equipment. The methods for calculating power of flat-sieve separators moving progressive and invers or circular progressive have clearly determined sense and consider all energy consumptions of separators’ engine. The goal of the calculation of technological equipment and sieve separators in particular is to define the power of the electric motors. The imperfection of existing methods for calculating power leads to use in some machines of high power engines which selection is based on indicative calculations, for example, using a method of specific energy consumption or comparing with analogues. As the calculating methods depend on the law of working parts movement and their engine each example considered separately. In the calculation of the power of separators with flat sieve which are moving oscillatory the effective power required by the engine of sieve bodies equal to the sum of the average power required to drive the oscillatory moving mass; the average power that is needed for product overclocking; the average power required to overcome the friction force of the product in the sieve; the average power used to deform the suspension; the average power need to overcome the drag of the air environment. The current value of the power which is need to drive the oscillatory construction elements is determined considering the total value of oscillatory bodies mass; the weight and the amount of sieve bodies; the product weight on the bodies sieves; the weight of the oscillator; the frame weight. During a circular progressive movement of sieve bodies the power which is need to overclock the product mass on the sieve which are moving reciprocally is almost equal to zero, because the product is moving with stops during the all-time being on the sieve. This also refers to the movement of the product on the barrel sieves which are rotating, where parts change the direction of movement while they are slipping down and get accelerated again. The acceleration power in the separators with circled progressive motion of the sieves is equal to the kinetic energy of its circle oscillations. To provide the relative motion of the parts on the horizontal sieve surface which is making a circled progressive motion it is necessary that the difference between the centred inertial force and friction force to be more than zero.

Published: February 2019

Defining company goals is one of the more difficult problems in the modern theory of firms. While such a goal has been clearly formulated in neoclassical theory (profit maximisation), in all modern conceptions it is difficult to find a consensus. A critical look at the neoclassical enterprise model has become the basis for the formulation of alternative business theories, such as managerial and behavioural theories. In these theories, two types of perception of objectives can be identified: theories assuming the existence of one main goal, other than the maximisation of profits (managerial theories) and theories assuming that companies implement a bundle of goals (behavioural theory).This article presents the main assumptions and ideas in managerial and behavioural theory in enterprise. This presentation is the basis for identifying the business objectives of companies that determine economic decision-making.

The article analyses the key problems facing the textile and clothing industry, including social and economic aspects of its functioning, and puts forward steps that could be taken to bring the industry closer to sustainable development. The issues discussed include outsourcing of the clothing and textiles production, salaries that can be 50% below a living wage, and fast fashion, which endangers the sustainable development approach to the production and consumption of textile products. The paper provides examples of initiatives aimed at achieving balance in areas including multilateral agreements, independent initiatives among clothing companies to improve pay conditions, respect for employee rights and ensuring safe working conditions, and also the popularisation of slow fashion movement, a response to the dominant phenomenon of consumerism.
The Technical Efficiency of Russian Retail Companies: An Empirical Analysis
Authors: Rogova Elena , Blinova Alina
Published: February 2019

This study focuses on the technical efficiency analysis of Russian retail companies over the period 2011–2015. The main objective is to assess technical efficiency and to reveal factors that affect the efficiency and creditworthiness of this important sector of the Russian economy. Efficiency can be considered a basic measure of creditworthiness because it demonstrates management’s ability to maximise its use of resources. Studying the results enables banks to consider creditworthiness and determine whether to provide retailers with funding for future development. The empirical analysis for this article was performed using Data Envelopment Analysis and Stochastic Frontier Analysis methods. Two differing methods can be used to evaluate technical efficiency. The first, SFA, presents a picture of the whole market and formulates general propositions on the creditworthiness of retail companies. The other method, DEA, looks at certain companies and their relative performance in comparison with their competitors. Banks can use a technical efficiency score to monitor the dynamics and potential of each company. In addition to examining tools for evaluating technical efficiency, the study also has practical implications for managers of retail companies in Russia.
Between Monologue and Dialogue in Social Life – the Philosophies of Martin Buber and Józef Tischner
Authors: Mizdrak Inga
Published: February 2019

Monologue and dialogue are contextual categories. They can be analysed from many different viewpoints, revealing their multiple meanings and their axiological-anthropological-social character. Both communication structures can refer to important social and individual problems.The article examines the meaning and importance of monologue and dialogue in social life. Martin Buber and Józef Tischner explain the real meaning of true (honest) dialogue, by pitting it against the monological way of living. They see dialogue as residing on the plane of life itself (Buber) and affecting the space “between” I and You (Buber, Tischner). Monologue seems to be not only the opposite of dialogue but also to be an incomplete structure that requires complementation. Buber and Tischner present dialogue as an essential human experience. The individual is described as an entity “invited to a conversation” (turned to the other and towards the other). Through this, they crystallise the essence of dialogue, in which freedom and responsibility play the key roles. Facing each other, the subjects must free themselves from prejudice and remove the armor of pretense. The answer to a question coming from another human being creates a dialogical bond of participation in values. Dialogue transcends the monological “being for oneself” of the subject, towards “being for others”. As a result, social reality gains a new meaning, becoming the space for reciprocity, solidarity and social life.

Published: February 2019

A biologia reprodutiva de Suiriri affinis (suiriri-do-cerrado) e S. islerorum (suiriri-da-chapada) é descrita pela primeira vez. O ninho de S. affinis é em forma de cesto raso, sendo construído com fibras vegetais e forrado por painas, sendo todas essas camadas firmemente unidas por grande quantidade de teia de aranha. O seu exterior é ornamentado com liquens e fragmentos de folhas secas. O ninho é apoiado pela base e laterais entre dois ou mais ramos divergentes. Embora superficialmente similar, o ninho de S. islerorum apresenta várias diferenças, sendo mais baixo, raso e apoiado pelas laterais entre uma forquilha. O seu interior é forrado por uma camada adicional de fibras vegetais por sobre as painas. A construção dos ninhos de ambas as espécies é exclusividade das fêmeas. Os ovos de S. affinis são branco-perolados (média de 20,8 x 15,1 mm, 2,5 g), enquanto que os de S. islerorum são creme claro (20,4 x 15,4 mm, 2,4 g), apresentando uma coroa de manchas marrons escuras ao redor do pólo rombo. Os filhotes de S. affinis apresentam a cabeça, superfície dorsal e coberteiras das asas marcadas por abundantes e diminutas manchas brancas, enquanto que os filhotes de S. islerorum são semelhantes aos adultos. A incubação é realizada exclusivamente pelas fêmeas, sendo estimada em 15,2 dias para ambas as espécies. Já os filhotes de S. affinis e S. islerorum permanecem no ninho por 18,9 e 18,3 dias, respectivamente. Algumas evidências sugerem que S. affinis apresenta alguma forma de reprodução cooperativa.

Authors: Kok Philippe J.R.
Published: February 2019

Anomaloglossus praderioi was originally described as Colostethus praderioi by E. La Marca in 1998 on the basis of two male specimens. The present paper provides a redescription of the species on the basis of new material from Maringma Tepui in Guyana and an additional specimen from Sierra de Lema in Venezuela. The redescription includes descriptions of the tadpole and vocalisation. Anomaloglossus praderioi is a medium-sized species mainly distinguished from its known congeners in having Fingers I, II and IV equal in length, the tip of Finger IV barely reaching the base of the distal subarticular tubercle on Finger III when fingers are adpressed, Fingers II and III with preaxial keel-like lateral folds, toes basally webbed with folded flaplike fringing except on Toes IV-V, symmetrical cloacal tubercles present, thin pale dorsolateral stripe present from tip of snout to tip of urostyle, ventrolateral stripe inconspicuous, never straight, oblique lateral stripe absent, throat in male grey to very dark grey, almost solid black, with black blotches, throat in female bright orange, almost immaculate. The tadpole is dark brown to black, exotrophic, benthic, LTRF 2(2)/3. The advertisement call consists of long trains of a single note repeated at a rate of 61-76 notes/min with a dominant frequency ranging from 3,562 to 3,856 Hz. The species is reported from eastern Venezuela and western Guyana and inhabits montane medium-canopy forest at elevations between 1,310-1,950 m above sea level.

Syntypes of Corydoras meridionalis Rodolpho von Ihering, 1911, once regarded as lost, were recently found in the collection of fishes of the Museu de Zoologia da USP. The syntypes had been identified as C. ehrhardti Steindachner, 1910, currently considered a senior synonym of that species. Examination of the rediscovered syntypes corroborates the proposed synonymy. Data on the syntypes are presented and compared with information in the original descriptions of C. ehrhardti and C. meridionalis; a few discrepancies found are discussed. A lectotype is designated for C. meridionalis and a photograph of the specimen is provided.

Authors: Nóbrega Paula Fernanda Albonette de , Pinho João Batista de
Published: February 2019

O conhecimento atual sobre o sucesso reprodutivo e características da história de vida da maioria das espécies de aves neotropicais é deficiente. A qualidade do habitat onde o ninho é construído é um dos fatores que influenciam o sucesso reprodutivo das aves. Este estudo objetivou determinar atributos da história de vida, assim como o padrão de uso de habitat a fim de compreender a dinâmica reprodutiva de Cantorchilus leucotis no Pantanal de Poconé, entre o rio Bento Gomes e Cuiabá, o qual é sujeito a alagamento de janeiro à abril. Cantorchilus leucotis foi registrado pelos métodos de captura com rede de neblina (1.560 horas), observação por censo auditivo (5.600 horas) e procura por ninhos (234 horas), durante os anos de 2001, 2002 e 2006. Foram encontrados 87 ninhos de C. leucotis durante as estações reprodutivas dos anos pesquisados, destes, 58 foram abandonados na fase de construção, quatro foram destruídos por intempéries climáticas, e apenas 25 ninhos chegaram à fase de postura de ovos. A porcentagem simples de sucesso reprodutivos foi de 12% (n = 25). A predação foi a maior causa de perda de ninhos ativos (76%). Desses ninhos, 94,7% encontrava-se em fase de ovo e 5,2% em fase de filhote. Dos 87 ninhos encontrados, 52 (59.8%) foram encontrados no Cambarazal, 26 ninhos (29.8%) no Brejo e nove ninhos (10.4%) no Landi. O parasitismo de ninho não foi observado. A espécie foi registrada ao longo de todos os anos de pesquisa, o que lhe conferiu o status de residente. O cambarazal, por se tratar de uma floresta úmida, apresentou locais ideais para confecção do ninho e a disponibilidade de alimento requerido pela espécie.

A new specie of Artigasia Christie, 1934 (Oxyurida: Hystrignathidae) from a Cuban passalid beetle
Authors: Morffe Jans , García Nayla
Published: February 2019

Artigasia milerai sp. nov. (Oxyurida: Hystrignathidae) is described from the gut caeca of Passalus interstitialis Escholtz, 1829 (Coleoptera: Passalidae) from Escaleras de Jaruco, La Habana province, Cuba (type locality) and El Pan de Matanzas, Matanzas province, Cuba. It differs from A. ensicrinata (Hunt, 1981), A. monodelpha (Travassos & Kloss, 1958) and A. pauliani Théodoridès, 1955 by having ridged eggs and a comparatively shorter tail. It also differs from A. monodelpha and A. pauliani by having a comparatively shorter esophagus, the vulva being slightly more posterior, and the extension of the cervical spines. It is close to A. ankaratrae Van Waerebeke, 1973 but can be differentiated by a stouter body, a comparatively shorter oesophagus and and the extension of the lateral alae.

La edad de los depósitos del Miembro Saladar se remonta al Mioceno Temprano alto/Mioceno Medio bajo. Los materiales son asignados a una nueva especie extinta del género viviente Genidens. Este nuevo taxón se distingue de todas las especies actuales por presentar un proceso supraoccipital muy corto, ancho y redondeado, extraescapular subcircular y mesetmoides amplios con una conspicua escotadura mesial, frontales prácticamente planos en vista lateral y margen lateral de los huesos esfenóticos rectilíneo. Genidens sp. nov., representa el registro más antiguo para el género y constituiría una especie de aspecto similar a las formas actuales del género. sp. nov., representa el registro más antiguo para el género y constituiría una especie de aspecto similar a las formas actuales del género.
A new species of Chaetostoma Tschudi (Siluriformes: Loricariidae) from Colombia with a definition of the C. anale species group
Authors: Ballen Gustavo A.
Published: February 2019

Chaetostoma formosae sp. nov. is described from piedmont tributaries of the upper río Meta on the Cordillera Oriental in Colombia. The new species is distinguished from its congeners by the presence of an elongate unbranched anal-fin ray with two posterior dermal ridges in mature males, the presence of strongly recurved cheek odontodes, the presence of a parieto-supraoccipital dermal keel, the posterior margin of the pelvic-fin strongly projected and angulate in shape in mature males, and by details of coloration. The new species belongs to an informal monophyletic group herein called the Chaetostoma anale species group, along with two additional species, C. anale and C. jegui, from Colombia and Brazil respectively, based on an apomorphic modification of the anal fin in mature males.

Com base na literatura e dados da coleção de Cecidomyiidae do Museu Nacional, Rio de Janeiro, a diversidade deste gênero no Brasil é avaliada, e informações sobre as espécies, seus hábitos e galhas são apresentadas. O gênero está representado, no Brasil, por 57 espécies (17 descritas e 40 não determinadas), o que corresponde a cerca de 16% do total de espécies descritas e 74% da fauna Neotropical. A maioria das espécies encontradas no Brasil é indutora de galhas (81%) e, destas, a metade induz galhas foliares. Gema, flor e caule foram outros órgãos vegetais galhados. As espécies estão associadas a trinta famílias botânicas, sendo mais comuns em Asteraceae, Myrtaceae e Verbenaceae. A maior parte foi coletada em Mata Atlântica, principalmente em restinga, e São Paulo suporta o maior número de espécies registradas. Oito registros novos de planta hospedeira são apresentados.
On the use of 10-minute point counts and 10-species lists for surveying birds in lowland Atlantic Forests in southeastern Brazil
Authors: Cavarzere Vagner , Costa Thiago Vernaschi Vieira da , Silveira Luís Fábio
Published: February 2019

Due to rapid and continuous deforestation, recent bird surveys in the Atlantic Forest are following rapid assessment programs to accumulate significant amounts of data during short periods of time. During this study, two surveying methods were used to evaluate which technique rapidly accumulated most species (> 90% of the estimated empirical value) at lowland Atlantic Forests in the state of São Paulo, southeastern Brazil. Birds were counted during the 2008-2010 breeding seasons using 10-minute point counts and 10-species lists. Overall, point counting detected as many species as lists (79 vs. 83, respectively), and 88 points (14.7 h) detected 90% of the estimated species richness. Forty-one lists were insufficient to detect 90% of all species. However, lists accumulated species faster in a shorter time period, probably due to the nature of the point count method in which species detected while moving between points are not considered. Rapid assessment programs in these forests will rapidly detect more species using 10-species lists. Both methods shared 63% of all forest species, but this may be due to spatial and temporal mismatch between samplings of each method.
New species of Neosilba McAlpine (Diptera: Lonchaeidae) and new records from Colombia
Authors: Galeano-Olaya Pedro E , Canal Nelson A
Published: February 2019

The Neotropical genus of lance flies Neosilba McAlpine could be found associated with fruits, flowers or buds of plants. There are few basic or applied studies of these insects, including data on taxonomy and/or economic importance. We described ten new species from Colombia: N. plana sp. nov., N. tolimensis sp. nov., N. amphora sp. nov., N. convexa sp. nov., N. concava sp. nov., N. orbata sp. nov., N. spiculata sp. nov., N. angusta sp. nov., N. distospinosa sp. nov. and N. piracea sp. nov. We presented a key for the all 40 valid species of the genus, included in five groups and two subgroups: major, parva, peltae, pendula and glaberrima groups. Glaberrima includes the two subgroups glaberrima and certa, and pendula includes the pendula and nigrocaerulea subgroups. Neosilba parva and N. bifida are reported for first time in Colombia.
Variación intraespecifica en el uso de Percha Nocturna de Basiliscus galeritus (Sauria: Corytophanidae) en Isla Palma, Pacífico Colombiano
Authors: Hernández-Córdoba Óscar Darío , Agudelo-Valderrama Olga Lucía , Ospina-Fajardo Juan Pablo
Published: February 2019

Las variaciones en el uso de percha nocturna son en parte un reflejo de la partición de recursos que permite la coexistencia al disminuir la competencia intraespecifica entre individuos de diferentes sexos y tamaños. En este trabajo se evaluó el uso de percha nocturna en los machos, las hembras y los juveniles de Basiliscus galeritus en Isla Palma - Pacífico Colombiano en abril de 2011. Los individuos fueron capturados manualmente y se tomó la información de la altura de la percha, posición en la que estaban perchados, longitud rostro cloacal y cobertura vegetal. Se registraron 39 individuos, encontrando que el tipo de percha utilizado con mayor frecuencia fueron las ramas (46,15%) seguido por las hojas (38,46%) y ocasionalmente fueron observados sobre lianas, suelo y tallos. Se evaluo el grado de asociación entre los sexos y cada una de las variables estudiadas con la altura de percha utilizando tablas de contingencia. No se detectó asociación alguna aunque el uso de percha estuvo relacionado con el tamaño corporal del individuo, independiente de su sexo. (rs = ‑0,08, p = 0,7).
Change in the meiofauna community structure of sandy beaches of the Nuevo Gulf (Chubut, Argentina)
Authors: Harguinteguy Carlos A. , Cofré M. Noelia , Pastor de Ward Catalina T.
Published: February 2019

The composition and distribution of the benthic meiofauna assemblages of the Nuevo Gulf (Chubut, Argentina) are described in relation to abiotic variables. The meiofauna and sediment samples were collected in the intertidal zone of four sandy beaches with different anthropic disturbances in June 2005. The samples were obtained at 20 sampling sites using a 2.5 cm diameter core tube at a depth of 10 cm. A total of 13 meiofauna taxa were identified, with the meiofauna being primarily represented by nematodes, gastrotrichs, ciliates and polychaetes and the meiofauna abundances ranging from 1.5 × 10³ to 6.5 × 10³ ind. 10 cm‑2. Univariate (one-way ANOVA test) and multivariate (ANOSIM/MDS test) analyses showed clear dissimilarities in community structures between sites with anthropic effects and those in pristine condition, revealed by the significant differences were found between beaches near to and far way from a city with port activity. The meiofaunal assemblage varied in abundance and diversity, and these changes in the community structure may have been related to environmental gradients on the shore. The BIO‑ENV analysis showed that the redox potential discontinuity depth might be the main factor in the spatial distribution of organisms.
Richness of hymenopterous galls from South America
Authors: Maia Valéria Cid
Published: February 2019

An overview of hymenopterous galls from South America is presented here based on literature as well as on data from the insect gall collection of the Museu Nacional/UFRJ. Seventy-three galls have been recorded on 71 host plants. Myrtaceae and Fabaceae are the plant families with the greatest number of galled species and gall morphotypes. Gall richness per plant species varied from one to two. The stem and bud were the most galled plant organs. The gallers comprise eight hymenopteran families, the best-represented being Eulophidae, Eurytomidae, and Cynipidae. Geographic records are restricted to six countries, and the majority is from Brazil.

Neoadjuvant cisplatin-based chemotherapy (NAC; 70 mg/m2) is standard of care for muscle-invasive bladder carcinoma (MIBC). Many patients (pts) cannot receive cisplatin because of renal impairment, and administration of cisplatin 35 mg/m2 on day 1 + 8 or 1 + 2 (i.e., split schedule) is a commonly used alternative. In this retrospective analysis, we compared complete (pT0) and partial (<pT2) pathologic response rates between split schedule (SS) and conventional schedule (CS) pts, after 1:1 matching on chemotherapy regimen, number of cycles, tumor histology, and clinical stage. Eighty matched pts were identified. pT0 rates were 17.5% (95% confidence interval [CI], 7%–33%) and 32.5% (95% CI, 19%–49%) in SS and CS cisplatin pts, respectively (p = .21), corresponding to an odds ratio for pT0 of 0.45 (95% CI, 0.16–1.31) with SS cisplatin. Split schedule cisplatin was associated with numerically but not statistically significant lower pathologic response rates relative to full dose.
