INFLUENCE OF NOZZLE TYPE AND SPRAY RATES ON CORN AND WEED PLANTS DROP DEPOSITIONS

The objective of this study was to evaluate different nozzles and spray rates on drop deposition in corn (Zea mays), Euphorbia heterophylla and Brachiaria plantaginea, both weeds located at and between crop rows. The experimental design established was complete random blocks with treatments arranged at 2 x 2 factorial scheme (2 nozzles types: DG11002VS flat flan and medium droplets, TXVK08 cone and very fine droplets; and 2 rates: 100 and 200 L ha(-1)) with four replications. The spray applications occurred at 13 days after corn germination (3-5 expanded leaves), when E. heterophylla and B. plantaginea plants had 2-4 and 2-3 leaves, respectively. Solution of Brilliant Blue (FD&C-1) dye at 3,000 ppm was used as spray tracer. It was concluded that the greatest average deposits in corn plants was provided by TXVK08, independently of the spray rates used. The most uniform deposits occurred when the spray rates of 200 L ha(-1) was used. Spray deposits were most uniform in B. plantaginea compared to E. heterophylla when both weds were located at crop row, independently of nozzle or spray rates. However, the DG 11002VS spray nozzle provided the most uniform drop deposition on B. plantaginea located between the rows, while the most efficient deposition over E. heterophylla located between rows was TXVK08.

Occurrence of heat waves in Triangulo Mineiro and Alto Paranaiba and their effect on milk yield and feed intake in cattle

The aim of this study was to estimate milk production and food consumption during the occurrence of heat waves in the Triangulo Mineiro and Alto Paranaiba, MG by means of bioclimatic zoning based on the Temperature and Humidity Index (THI). Therefore a history of heat wave occurrence between the years 2000-2010 was compiled. The decline in milk production (DMP) and reduced food consumption (RFC) were simulated in cities where periods of heat waves were identified. Frutal and Ituiutaba had the highest rate of heat wave occurrence per year. The DMP and RFC showed bioclimatic differences between the cities of Uberaba, Ituiutaba and Frutal. The cities with the best bioclimatic conditions were Sacramento and Patrocinio, as they presented a THI classified outside of the emergency range, with a night THI of below 76 and without heat waves. Therefore, the occurrence of heat waves can impair food intake and decrease milk production, thereby most effectively demonstrating the effects of thermal stress on dairy cows in the Triangulo Mineiro and Alto Paranaiba, MG region.

GASTROPOD SHELLS USED BY Dardanus insignis (Decapoda, Anomura) NEAR ISLANDS IN THE UBATUBA REGION, SAO PAULO, BRAZIL

The use of gastropod shells by hermit crabs is determined by the availability of shells in the environment or through selection for size and volume. This study analyzed patterns in the use of shells by Dardanus insignis (Saussure, 1858). From January 1998 to December 1999, 386 individuals were collected from two islands at Ubatuba, Sao Paulo. The crabs were measured for cephalothoracic shield length (CSL) and wet weight (CWW). The gastropod shells occupied by hermit crabs were identified, and the shell aperture width (SAW), dry weight (SDW) and internal volume (STY) were measured. The relationships between the dimensions of the gastropod shell and the hermit crabs were evaluated by linear regression analysis. Among the 11 species of gastropod shells used by D. insignis, the most often used was Olivancillaria urceus (31%), followed by Strombus pugilis (22%) and Siratus tenuivaricosus (18%). The shell of O. urceus was used most probably due to its high availability on Couves and Mar Virado islands. The most significant biometric parameter was shell aperture width (F=18.231; p<0.0001), highlighting the importance of this variable for the shell choice by D. insignis at both sites.

MORPHO-PHYSIOLOGICAL INDICES AND ECONOMIC PRODUCTIVITY OF JAMBU CULTIVARS INFLUENCED BY THE ORGANIC AND MINERAL FERTILIZERS

The jambu belongs to the family Asteraceae, tropical crop, nowadays, this plant has been considered as a promising vegetable crop, because to its pharmacological properties. Despite this novelty, the vegetable remains invisible in the statistics of production and market in the state of Para, Brazil. This research was carried out with the aim of comparing the economic productivity and phenological development by the morpho-physiological growth indexes of two cultivars of jambu organic manure and mineral fertilizers. The experiment was carried out at the Sao Manuel Experimental Farm (Sao Manuel-SP), which belongs to the Faculdade de Ciencias Agronomicas - UNESP, campus Botucatu. The experimental design was a factorial randomized blocks (2 x 2) with two fertilization (organic and mineral) and two cultivars (Jambuarana and Nazareth), with six replications, two fertilization (organic and mineral) and two cultivars (Jambuarana and Nazareth). The following characteristics were evaluated: Plant height (cm), Leaf area (cm(2)), Fresh mass (g), Dry mass (g), Leaf area index (LAI), Leaf area ratio (LAR), Specific leaf Area (SLA), Leaf Weight Ratio (LWR), Amount of water in the plant (QAPA) (g per plant set), Leaf specific weight (LSW) (g cm(-2) per plant set) and Economic productivity. All data were statistically analyzed by analysis of variance and the Tukey test (1%) for mean comparison, with the software SISVAR. In the conditions of this experiment was carried out, it was possible to verify that the cultivar Jamburana had not only a good agronomic development and economic productivity under organic fertilization but also the best morpho-physiological indexes, showing that this kind of fertilization increases the agronomic effectiveness of this cultivar.

Diga-me quem tu és: o léxico-marketing na publicidade e o comportamento de gêneros sociais

It is unanimous among lexicologists that lexical units present deep marks in the representativeness of cultural and behavioral issues. Thus, some scholars have been proposing methodologies in order to enable the verification, scientifically, of mechanisms to systematize the lexicon within a specific time/space. In this way, it would be possible to promote discussions about its relations with social matters. These lexical contents can be analyzed, for instance, in the publicity having in mind its power of extending the desires of its receiver/customer to the acquisition of products/services since it is a media outlet that provide aids, by means of verbal texts produced by advertising editors, in order to deal with issues of our society, as those related to female and male genders. From all of this, the present article aims at organizing lexical items in market segments, here referred to lexicon-marketing, so as to make possible observation of social behaviors in the universes of both women and men.

Turpilóquio em português e italiano: reflexões sobre marcas de uso de itens tabus em dicionários

In this paper, we tried to understand the place of taboo words and their importance in the language. We focused questions about the taboo and how words can be prohibited. We elected swear words as our object of research because these words have an important place in the lexicon of many speakers, and they are present in books and movies, as well as in the everyday speech. Therefore, we tried to show that they must be analyzed with attention and also free from prejudices. We found out that the use of bad words can be very different in the languages selected and they reflect thus the culture of the languages involved.

A nova teoria da antropologia da civilização: tradução para a língua inglesa de neologismos terminológicos criados por Darcy Ribeiro nas obras o processo civilizatório e o povo brasileiro

This study analyzes the translation process into English of neologisms and expressions in the works written by the anthropologist Darcy Ribeiro and in their respective translations, made by Betty J. Meggers and Gregory Rabassa. Our research project draws on Corpus-Based Translation Studies (BAKER, 1995, 1996, 2000; CAMARGO, 2007), Corpus Linguistics (BERBER SARDINHA, 2004) and on some concepts of Terminology (ALVES, 1999; BARROS, 2004; BOULANGER, 1989; CABRÉ, 1993, 1999). Results show that terms do not present similarities within the language related to Brazilian Anthropology, being necessary for the author to look up alternative terminology and to create new concepts that can be used by other anthropologists. The translation of words and expressions developed by the author reflects lexical variation due to the options chosen by the respective translators for the target language. These tendencies may be found in Ribeiro’s translated texts, indicating the difficulty to conceptualize the anthropological Brazilian universe in English.

Lematização de unidades fraseológicas diacríticas em dicionários bilíngues espanhol/português

In this paper we consider a broad conception of phraseology to propose a description and analysis of phraseological units of stemming diacritical Spanish / Portuguese bilingual dictionaries. The focus of the analysis seeks to show not only the organization of the macro-structure proposed by two different lexicographical works, but also to discuss the use of labels and equivalences presented. Phraseological units are understood here as diacritical phraseologisms containing unique lexias, lacking syntactic and semantic autonomy recognized by speaker only within fixed expressions.

O morfema de gerúndio 'ndo' no Português Brasileiro: análise fonológica e sociolinguística

Neste artigo, tratamos do processo fonológico de apagamento do /d/ no morfema de gerúndio “ndo” em uma variedade do Português Brasileiro. Com base em análise acústica e perceptual, verificamos que, quando /d/ tem seus parâmetros acústicos alterados, os ouvintes percebem seu apagamento no morfema de gerúndio. Essa correlação, porém, não é categórica. A regra de apagamento do /d/ é variável e se aplica somente a formas de gerúndio. Esses fatos levam ao desafio de interpretar o processo ou como regra lexical ou como poslexical. Fundamentados nos pressupostos da Fonologia Lexical, defendemos que se trata de regra lexical. Na análise variacionista do fenômeno, analisamos 76 amostras de fala constituídas a partir do controle das variáveis sociais sexo/ gênero, idade e escolaridade. Constatamos que homens jovens e com poucos anos de escolaridade são os que mais aplicam o apagamento de /d/ nas formas de gerúndio, o que nos permite concluir, com base em hipóteses clássicas da atuação de variáveis sociais, que tal fenômeno é estigmatizado na comunidade de fala estudada.

As orações concessivas nas gramáticas e nos livros didáticos do Ensino Fundamental: análises e novas propostas

This paper aims to discuss the approach of sentences concessive on grammars and teaching books in Portuguese in order to ascertain to what extent is closer or more distant from the description of sentences concessive in real interaction from the perspective of Functional Discourse Grammar. Were consulted normative grammars, descriptive and five textbooks used in primary schools. In some, the grant was not addressed, as in others, we note that, in general, have definitions which simply equate concessive clauses a concept syntactic and sometimes semantic, detaching it from the domain of pragmatic language. This level of analysis is not left out, however, by the prospect Functional Discourse, which analyzes the pragmatic as the broader component within which we analyze the semantics and syntax. From this point of view, we intend to propose new emphases in approach given the award by the grammars and the teaching materials.

As orações subordinadas substantivas em função de sujeito: questões de ensino

This paper attempts to answer how the descriptive analysis of the substantive subordination clauses made within the realm of academic research can contribute to the effective teaching of those structures in the Elementary School. After showing how the subordination has been treated in grammar school and textbooks and pointing at some recurring problems in the presentation of the subject, we present the treatment of subordinate clauses with the function of subject in two descriptive grammars of Portuguese, in order to ascertain to what extent the relevant aspects of the description of those clauses are related to the traditional way of teaching. From those descriptive works, we selected some functional features considered to be essential for the treatment of the subject in the Elementary School.

Oficinas de leitura, interpretação e produção textual no ensino fundamental

This paper describes a project called “Development of educational workshops on text reading, interpretation and writing in elementary school”, which took place at the São Paulo State University (UNESP) with financial support given by the PROEX-UNESP (Pro-Rectorate of Extension). This project aimed to organize and run educational workshops on reading, interpreting and writing different genres for students enrolled at a public elementary school in São José do Rio Preto, São Paulo state. The analysis of the texts produced by the students unfolded the project into two essential approaches. In the first one, it was possible to identify problems and inaccuracies in language usage, which was the starting point to prepare the minicourses that would be offered. These mini-courses promoted a deep involvement of undergraduate students (in Portuguese Language and Literature) with the practice of Portuguese teaching at the school. In the second one, 5.468 texts, which were produced during the four-year project, founded researches whose goal is to describe processes in which there is a relation between speech and writing, and are based on a theoretical framework that values the multiplicity of literacies associated with social practices experienced by the students. Thus, this extension project aimed to articulate the service to the external community – in this case, public school students - to the internal community – undergraduate students in Portuguese Language and Literature.

O uso da aprendizagem baseada em problemas e a atuação docente

Recent national education policy documents have emphasized the importance of methodologies and problem-centered learning processes. The purpose of this article is to promote reflection on the problem-based learning (PBL) understood as a methodology that favors learning processes and the active role of students. PBL emerged in undergraduate medical and has been gaining ground not only in higher education but also in basic education. This conception of teaching-learning breaks with the traditional relationship teacher-student- knowledge, introducing new dynamics of relationships between subjects and those with knowledge. From this perspective the educational performance turns and brings new challenges to the teacher.
