Desenvolvimento radicular de híbridos de mamona submetidos à adubação potássica

A deficiency of potassium at the beginning of the season affects the nutritional balance implicating the proper development of plants. The objective of this study was to evaluate the effect of potassium (K) in the root system development and production of dry matter of shoots of hybrid castor. The experiment was a 5 x 2 factorial scheme in a completely randomized design with four replications. The treatments consisted of five doses of K: 0, 25, 50, 100 and 200 ppm and two hybrids of castor (Lyra and Savana). After 45 days after emergence, there was a collection of shoot and root system of plants. The evaluations were: length, area, diameter and dry root and shoot. The addition of potassium caused increased root diameter at the hybrid Savana and reduced at the Lyra. The production of root and shoot dry of the hybrid Savana decreased with doses from 78 and 116 ppm of potassium, respectively.

Concepção detalhada de uma bancada para simular esforços mecânicos em colunas de perfuração

In this work we study the construction of a test rig made to simulate the Mechanical efforts in wich a drillstring is submitted. The model is based on the rig built at IDS, Germany. There are some fault liabilities while doing the project of the axis. Therefore it's important to analyze and take knowledge of this efforts in order to predict failures like rupture or fatigue collapse. The main objective of this theis is to show the operating principle of the test rig and it's construction. The accomplished study allow us to predict the drillstring behavior and from the economic point of view that is very important because failures results in equipments maintenance that requires time and money causing prejudice to the company. Using SolidWorks, a simulation software, the thesis approaches all the mechanical parts required for it's construction as well as it's working principle. Acquisition sensors like strain gauges, accelerometer, and torque transductor were also used in this model. The objective of this thesis is to create a simulation model to be eventually at FEG(UNESP). During the development of the study, it was possible to learn more about the drilling process and the mechanical efforts in which the drill pipe is submitted. The accomplished contributed with knowledge for the student in the drilling process area. Also during the development of the study it was possible to have contact with different areas of engineering but the study is specifically directed to the construction of the test rig. Therefore the main theme of this thesis is to show the operating principle of the test rig and it's construction

Gene copy number and differential gene expression in haploid and diploid males of the stingless bee, Melipona quadrifasciata

Complementary sex determination in Hymenoptera implies that heterozygosity at the sex locus leads to the development of diploid females, whereas hemizygosity results in haploid males. Diploid males can arise through inbreeding. In social species, these pose a double burden on colony fitness, from significant reduction in its worker force and through being less viable and fertile than haploid males. Apart from being "misfits", diploid males are of interest to assess molecular correlates for possibly ploidy-related bionomic differences. Herein, we generated suppression subtractive cDNA libraries from newly emerged haploid and diploid males of the stingless bee Melipona quadrifasciata to enrich for differentially expressed genes. Gene Ontology classification revealed that in haploid males more DEGs were related to stress responsiveness, biosynthetic processes, reproductive processes and spermatogenesis, whereas in diploid ones differentially expressed genes were associated with cellular organization, nervous system development and amino acid transport were prevalent. Furthermore, both libraries contained over 40 % ESTs representing possibly novel transcripts. Quantitative RT-PCR analyses confirmed the differential expression of a representative DEG set in newly emerged males. Several muscle formation and energy metabolism-related genes were under-expressed in diploid males. On including 5-day-old males in the analysis, changes in transcript abundance during sexual maturation were revealed.

RGMa and RGMb expression pattern during chicken development suggest unexpected roles for these repulsive guidance molecules in notochord formation, somitogenesis, and myogenesis

Background: Repulsive guidance molecules (RGM) are high-affinity ligands for the Netrin receptor Neogenin, and they are crucial for nervous system development including neural tube closure; neuronal and neural crest cell differentiation and axon guidance. Recent studies implicated RGM molecules in bone morphogenetic protein signaling, which regulates a variety of developmental processes. Moreover, a role for RGMc in iron metabolism has been established. This suggests that RGM molecules may play important roles in non-neural tissues. Results: To explore which tissues and processed may be regulated by RGM molecules, we systematically investigated the expression of RGMa and RGMb, the only RGM molecules currently known for avians, in the chicken embryo. Conclusions: Our study suggests so far unknown roles of RGM molecules in notochord, somite and skeletal muscle development. Developmental Dynamics, 2012. (C) 2012 Wiley Periodicals, Inc.

Speech perception and cortical auditory evoked potentials in cochlear implant users with auditory neuropathy spectrum disorders

Objective: To characterize the PI component of long latency auditory evoked potentials (LLAEPs) in cochlear implant users with auditory neuropathy spectrum disorder (ANSD) and determine firstly whether they correlate with speech perception performance and secondly whether they correlate with other variables related to cochlear implant use. Methods: This study was conducted at the Center for Audiological Research at the University of Sao Paulo. The sample included 14 pediatric (4-11 years of age) cochlear implant users with ANSD, of both sexes, with profound prelingual hearing loss. Patients with hypoplasia or agenesis of the auditory nerve were excluded from the study. LLAEPs produced in response to speech stimuli were recorded using a Smart EP USB Jr. system. The subjects' speech perception was evaluated using tests 5 and 6 of the Glendonald Auditory Screening Procedure (GASP). Results: The P-1 component was detected in 12/14 (85.7%) children with ANSD. Latency of the P-1 component correlated with duration of sensorial hearing deprivation (*p = 0.007, r = 0.7278), but not with duration of cochlear implant use. An analysis of groups assigned according to GASP performance (k-means clustering) revealed that aspects of prior central auditory system development reflected in the P-1 component are related to behavioral auditory skills. Conclusions: In children with ANSD using cochlear implants, the P-1 component can serve as a marker of central auditory cortical development and a predictor of the implanted child's speech perception performance.

Early malnutrition decreases contrast sensitivity to circular concentric gratings

Early malnutrition refers to inadequate nutrition during the critical period of nervous system development followed by nutritional recovery, resulting in a short stature according to age but normal weight according to short stature. We measured the effects of early malnutrition on contrast sensitivity (CS) to concentric circular gratings in 18 children of both sexes, aged 8 to 11 years (mean = 9.2 years, standard deviation = .99 years). Nine of the children were eutrophic (E group), and nine experienced early malnutrition (EM group) based on state healthcare records and Waterlow's anthropometric parameters. Contrast sensitivity to four spatial frequencies (.25, 1.0, 2.0, and 8.0 cycles per degree [cpd]) was measured using a temporal two-alternative forced-choice psychophysical method with mean luminance of 40.1 cd/m². Statistical analyses showed significant differences between groups and a group × frequency interaction. EM group was significantly less sensitive than the E group to the 8.0 cpd frequency and needed 1.49-times more contrast to detect the gratings. These results suggest that early malnutrition impairs CS to high-spatial-frequency concentric circular gratings in children. Therefore, early malnutrition, which is known to affect primary visual cortical areas, may also affect higher visual cortical areas such as V4 and the inferotemporal cortex.

Politiche di sviluppo e questione etnica. La cooperazione italiana IN Bosnia Erzegovina

The globalization process of the last twenty years has changed the world through international flows of people, policies and practices. International cooperation to development is a part of that process and brought International Organizations (IOs) and Non Governmental Organizations (NGOs) from the West to the rest of the world. In my thesis I analyze the Italian NGOs that worked in Bosnia Herzegovina (BH) to understand which development projects they realized and how they faced the ethnic issue that characterized BH. I consider the relation shaped between Italian NGOs and Bosnian civil society as an object of ethnic interests. In BH, once part of former Yugoslavia, the transition from the communist regime to a democratic country has not been completed. BH’s social conditions are characterized by strong ethnic divisions. The legacy of the early 1990s crisis was a phenomenon of ethnic identities created before the war and that still endure today. The Dayton Peace Agreement signed in 1995 granted the peace and reinforced the inter-ethnic hate between the newly recognized three principal ethnicities: Serbs, Croats and Bosniak. Through the new constitution, the institutions were characterized by division at every level, from the top to the bottom of society. Besides it was the first constitution ever written and signed outside the own country; that was the root of the state of exception that characterized BH. Thus ethnic identities culture survived through the international political involvement. At the same time ethnic groups that dominated the political debate clashed with the international organization’s democratic purpose to build a multicultural and democratic state. Ethnic and also religious differences were the instruments for a national statement that might cause the transition and development projects failure. Fifteen years later social fragmentation was still present and it established an atmosphere of daily cultural violence. Civil society suffered this condition and attended to recreate the ethnic fragmentation in every day life. Some cities became physically divided and other cities don’t tolerated the minority presence. In rural areas, the division was more explicit, from village to village, without integration. In my speech, the anthropology for development – the derivative study from applied anthropology – constitutes the point of view that I used to understand how ethnic identities still influenced the development process in BH. I done ethnographic research about the Italian cooperation for development projects that were working there in 2007. The target of research were the Italian NGOs that created a relation with Bosnian civil society; they were almost twenty divided in four main field of competences: institutional building, education, agriculture and democratization. I assumed that NGOs work needed a deep study because the bottom of society is the place where people could really change their representation and behavior. Italian NGOs operated in BH with the aim of creating sustainable development. They found cultural barricade that both institutions and civil society erected when development projects have been applied. Ethnic and religious differences were stressed to maintain boundaries and fragmented power. Thus NGOs tried to negotiate development projects by social integration. I found that NGOs worked among ethnic groups by pursuing a new integration. They often gained success among people; civil society was ready to accept development projects and overcome differences. On the other hand NGOs have been limited by political level that sustained the ethnic talk and by their representation of Bosnian issue. Thus development policies have been impeded by ethnic issue and by cooperation practices established on a top down perspective. Paradoxically, since international community has approved the political ethnic division within DPA, then the willing of development followed by funding NGOs cooperation projects was not completely successful.

Prove accelerate per la verifica strutturale di trattrici agricole

The needs of customers to improve machinery in recent years have driven tractor manufacturers to reduce product life and development costs. The most significant efforts have concentrated on the attempt to decrease the costs of the experimental testing sector. The validation of the tractor prototypes are presently performed with a replication of a particularly unfavourable condition a defined number of times. These laboratory tests do not always faithfully reproduce the real use of the tractor. Therefore, field tests are also carried out to evaluate the prototype during real use, but it is difficult to perform such tests for a period of time long enough to reproduce tractor life usage. In this context, accelerated tests have been introduced in the automotive sector, producing a certain damage to the structure in a reduced amount of time. The goal of this paper is to define a methodology for the realization of accelerated structural tests on a tractor, through the reproduction of real customer tractor usage. A market analysis was performed on a 80 kW power tractor and a series of measures were then taken to simulate the real use of the tractor. Subsequently, the rainflow matrixes of the signals were extrapolated and used to estimate the tractor loadings for 10 years of tractor life. Finally these loadings were reproduced on testing grounds with special road pavements. The results obtained highlight the possibility of reproducing field loadings during road driving on proving grounds (PGs), but the use of two field operations is also necessary. The global acceleration factor obtained in this first step of the methodology is equal to three.

Phylogenie und Biogeographie der Linoideae (Linaceae) - Evolution von Heterostylie, Homostylie in Linum

Die Linaceae-Linoideae, vor allem die Gattung Linum, wurden unter Verwendung von zwei molekularen Markern (rbcL und ITS) bzgl. ihrer Phylogenie und Biogeographie untersucht. Die Linaceae entstanden während der mittleren Kreide in den frühen tropischen Regenwäldern, von wo aus sich die monophyletischen Linoideae vor etwa 51-46 Mill. Jahren über die temperaten Gebiete der Nordhemisphäre ausbreiteten. Während die drei basal abspaltenden Gattungen Anisadenia, Reinwardtia und Tirpitzia bzgl. ihrer Verbreitung auf Südostasien beschränkt sind, ist die Gattung Linum heute auf allen Kontinenten vertreten. Der Ursprung von Linum liegt wahrscheinlich in Südwestasien bzw. dem östlichen Mediterraneum, wo es im Oligozän zur Aufspaltung in zwei Entwicklungslinien kam ('Blaue Gruppe' und 'Gelbe Gruppe'). Während die überwiegend blaublühenden Linum-Arten ('Blaue Gruppe') vor allem in Europa und Südwestasien vorkommen, weisen die Vertreter der 'Gelben Gruppe' ein wesentlich größeres Verbreitungsgebiet auf. Gelbblühende Linum Arten findet man auf allen Kontinenten mit Diversitätszentren in Nordostamerika und Südwestasien. Interessanterweise wurde Amerika zweimal unabhängig voneinander besiedelt. Während die gelbblühenden Arten vor etwa 22-20 Mill. Jahren von Westeuropa über den Atlantik den amerikanischen Kontinent erreichten, wanderten Vertreter der 'Blauen Gruppe' im Pliozän (vor 3.78-3.33 Mill Jahren) über die Bering-Landbrücke in die Neue Welt ein. Auch in Südafrika sind einige gelbblühende Linum-Arten zu verzeichnen, die nicht über Nordafrika (wo einige Arten der 'Gelben Gruppe' beheimatet sind) die südliche Spitze des Kontinents erreichten, sondern von Amerika aus. Die molekularphylogenetischen Ergebnisse legen eine Eingliederung der Gattungen Cliococca, Hesperolinon, Radiola und Sclerolinon in Linum nahe, die durch morphologische Merkmale gestützt wird. Linopsis, die artenreichste Sektion der Gattung Linum, bedarf einiger Umstrukturierungen auf der Basis der molekularen und morphologischen Daten. Ein interessantes Phänomen innerhalb der Linaceae ist das Vorkommen von heterostylen und homostylen Arten innerhalb der Familie. Die Kombination der molekular-phylogenetischen Ergebnisse mit morphologischen Beobachtungen des Reproduktionssystems lassen darauf schließen, dass sich Homostylie innerhalb von Linum mehrfach unabhängig voneinander entwickelt hat. Das Modell von Primula wurde als Grundlage verwendet, um Aufschluss über die Entstehung der Homostylie innerhalb von Linum zu erlangen. Aus Primula ist bekannt, dass eine Kopplungsgruppe aus mindestens drei Genen an der Vererbung von Heterostylie beteiligt ist: G/g kodiert hierbei die Griffellänge und die Selbstinkompatibilitäts-reaktion der Narbe, A/a die Länge der Filamente und P/p die Selbst-inkompatibilitätsreaktion des Pollens. Umfangreiche Kreuzungs-experimente einer homostylen und einer heterostylen Linum-Art deuten darauf hin, dass die Genotypen der beiden Blütenformen in heterostylen Linum-Arten denen in Primula entsprechen. Langgriffel sind hiernach homozygot rezessiv (gpa/gpa), während die Kurzgriffel heterozygot sind (GPA/gpa). Selbstkompatible, homostyle Arten können theoretisch durch verschiedene Rekombinations-ereignisse entstehen. Erste Ergebnisse der rasterelektronen-mikroskopischen Betrachtung der Pollenkornoberflächen und Narbenpapillen deuten darauf hin, dass innerhalb von Linum Homostylie durch unterschiedliche Rekombinations-ereignisse mehrfach aus heterostylen Arten entstanden ist. So besitzt die homostyle Linum leonii den Genotyp gPA/gPA, während für die homostylen L. tenuifolium und L. nodiflorum der Genotyp Gpa/Gpa wahrscheinlich ist.
