Current cattlemen must seek methods to maximum reproductive efficiency of their beef herds, making the business competitive and enhancing greater profitability. For the cow-calf producers, efficiency translates into more cows producing one calf every year. Fixed-time artificial insemination (TAI) is one of several technologies that producers utilize to reach this goal. Postpartum anestrus is one of the biggest obstacles to overcome in order to obtain suitable results at the end of the breeding season. The TAI protocols are efficient in re-establishing cyclicity in noncycling cows during the postpartum period, streamlining the use of labor on farms, allowing the use of artificial insemination (AI) on a large scale, and introducing superior genetics to the herd. The protocols that are most commonly used in Brazil are based on progesterone (P4) releasing devices that prevent premature estrus and ovulation; and estradiol (E2) to synchronize the initiation of a new follicular wave. In such protocols, administration of equine chorionic gonadotropin (eCG) helps the development of the follicle, increases ovulation rate, improves the endocrine and uterine environment during proestrus and diestrus, and improves fertility. The use of eCG in TAI protocols for suckled cows, non-lactating cows and heifers increases the pregnancy rate allowing more calves at the end of the breeding season and higher profitability to the cattlemen

This Work focuses the importance of children‟s literature with the insertion of authors‟ like Aesopo, La Fontaine and Monteiro Lobato in the early years of elementary school, so that children could develop their reading that could bring reflections about the use of the language. It entends to show that books can give kids maturity to notice that when it comes to language there‟s not righ or wrong, but contexts that they should fit, in so that they can communicate and decrease the language prejudice. The authors studied in this study are the ones who study the language, the importance of children‟s literature and language prejudice at schools. This work was done through quantitative and qualitative approach, divided into 2 parts, observation and interventions, the research could be in touch with the observed class and get information about the students. Later the researcher could act by telling stories and get data. A third-grade class in a public school in the year of 2010, was observed during the internship in the early years of elementary school compared to another fourth grade class of another public school. The results and analisis oh the data show kids‟ lack of contact with an appropriate children‟s literature, like the fables which are short tales with moral and romance like Emília no País da Gramática by Monteiro Lobato, would make it difficult to learn the production of consistent texts and appropriate language in different contexts. Schools play an important role for kids to be in touch with these good books, so they should have the main role in the children‟s development and background, making them able to be aware of the importance of reading and writing in their lives. Most of the children found it difficult to write texts, but in the end they reached a god level of language related to the proposed context, writing consistent texts, but the part of children still mistake and in literacy and language adaptation

Atualmente, as pesquisas acadêmicas e industriais não estão voltadas apenas para a descoberta de novos fármacos, mas também para novas maneiras de administração de medicamentos pretendendo obter melhores ações farmacológicas alem de reduzir efeitos colaterais. Partindo deste pressuposto, estudos demonstram que inúmeras moléculas podem ser incorporadas a polímeros híbridos orgânico-inorgânico preparados pelo processo sol-gel, assim pretende-se estudar a possibilidade de sua aplicação no desenvolvimento de um dispositivo de liberação controlada de fármacos na forma de implantes subcutâneos. As matrizes hibridas para serem implantadas devem, necessariamente, ser estéreis. Para isto este trabalho analisa a interação entre o processo de esterilização e uma provável alteração estrutural nestes polímeros. A esterilização por calor úmido em autoclave e a esterilização por radiação gama foram escolhidas para analisar a correlação entre alteração estrutural do hibrido e o processo de eliminação de microorganismos. Outro aspecto que levamos em consideração foi a melhora das características mecânicas das matrizes poliméricas confeccionadas com poli óxido etileno de peso molecular 1900 (POE 1900) e poli óxido propileno de peso molecular 400 (POP 400). Para serem implantadas estas matrizes devem estar uniformes, e não podem trincar ou quebrar antes ou após a implantação. Considerando estes fatores foi adicionado as amostras um agente plastificante, o álcool polivinílico (PVA), na tentativa de melhorar estas características

Acupuncture is one of the oldest forms of treatment, which is based in the grounds of Traditional Chinese Medicine. Despite the ancient history, it’s not completely widespread in Brazil, neither so comprehensive in veterinary medicine as used in humans. The technique of inserting needles into acupuncture points, can also be stimulated by heat, electrical stimulation or implants of metal, is mainly focused on neuromuscular disorders in small animals. The difficulty of comprehension of language and the lack of cientific bases restricted the possible applications of acupuncture. This work will address some of the clinical situations this complementary treatment can act, such as neurological, cardiorespiratory, reproductive, gastrointestinal, immunological, and postoperative intensive care

With the growth of the demand on electric energy in the last decades, the urban distribution and transmission systems have experienced a bigger necessity to improve on the substations, the automation procedures and techniques on the operation maneuvers of such systems, in a sense that better attends the quality levels, availability, continuity and operational reliability. In this way, the objective of the present paper is to perform a study of protection and control on an electrical industrial system involving the procedures of digitizing and maneuvers automatism utilizing operational techniques and other pertinent information used in a typical high-voltage Industrial Electrical System. Analysis were made on short-circuits to specify the main components of the 138 [kV] substation, in addition, there were used digital MiCOM relays to make the protection of the present elements. With that, a program was developed to allow the user to monitor the condition of circuit-breakers through a supervision screen being able to simulate some kinds of faults, as well as observing the characteristics of each device. This way, the importance of having a fast and reliable system that ensures the equipment’s protection and the industrial process continuity due to faults on the electrical system is noticeable. It’s important to highlight that all this digitizing was mainly favored by the development of digital technology on the last years, mainly on microelectronics, also with the appearance of supervision gadgets allowing the development of complex systems in supervision and electric energy control

The NbCl5 being a strong electrophile, is a potential candidate to act as a Lewis acid, and therefore it mediates various organic reactions. For this reason, it has received continuous attention by Brazilian researchers, especially in recent decades, since Brazil holds the largest reserves of niobium, besides being the largest producer of this element. The Michael addition reaction is one of the most widely used for forming carbon-carbon bonds and takes place by the addition of nucleophiles to activated olefins. Although this type of reaction is usually catalyzed by base, there are reports in the literature on the use of various Lewis acids in this type of reaction. The synthesis of enamines based acetilenodicarboxilates and amines, aromatic or alkyl, by Michael addition reaction is quite interesting, since these are valuable synthetic intermediates for the synthesis of heterocyclic and they are used in multicomponent reactions. The derivatives of anilino-fumarate also have a great potential for medical application. In this study we investigated the use of niobium pentachloride as Lewis acid to catalyze the Michael additions between the derivatives of aniline and acetilenodicarboxilates the synthesis of enamines

The modernist poet Emílio Moura (1902-1971) incorporates a strictly modern language regarding the imagistic suggesting a mainly poetry metalinguistic. That way, from the works Canto da hora amarga (1932) and Cancioneiro (1944) we attest, through the poetic analysis, that modernity Moura’s poetry takes place in confluences with ideas ranging from biblical tradition and come to the depersonalization of the modern I and questing. We objectify, therefore, demonstrate and explore the metalinguistic and intertextual character that results in the personification of poetry, as clarified muse. To achieve this, this same poetry undergoes a dualistic and pessimistic sentiment, baroque, the I that is divided into life and death, light and shadow; goes through a romantic feeling of anguish and desolation and reaches the multiplicity of the poetic speaker, which promotes a constant struggle with the language. More than draw a correlation between classical and modern ideas (in the sense that the poet creates depersonalization and appropriates of free, short prose or verse, typical of modernism), intend to supply, at least in part, the dearth of studies on the miner poet who has found fertile ground to question and analyze internally the role of poetry in the multiplicity of man and modern society to therefore conclude that universalism the Emílio Moura becomes distinctive and mature. Thus, we will check how poetic inflows corroborate both works for reevaluation and critical insertion of poetic the Emílio Moura in the context of modern/Modernist Brazilian literature

Titanium and its alloys has been widely used as materials for metallic biomaterials implants are usually employed to restore the hard tissue function, being used for artificial joints and bones, synthetic plates, crowns, dental implants and screws . Objective of this work was the surface modification of Ti-alloy 25Ta from biomimetic surface treatment of employment and deposition of polymer by electrospinning. The league was obtained from the fusion of the pure elements in the arc furnace with controlled atmosphere. The ingots were subjected to heat treatment, cold forged and sectioned discs with 13 mm diameter and 3 mm thick. Two surface treatments was evaluated, biomimetic and electrospinning with PCL fiber. The biomimetic treatment was performed involving alkaline treatment for three molarities 1.5M, 3M and 5M with immersion in SBF. The electrospinning was performed using PCL polymer alloy surface after the alkali treatment Ti25Ta 1M. For this group the polymer coated surfaces were immersed in calcium phosphate containing solution for immobilization of apatite. The results were compared with previous studies using surface treatment group to verify hydroxyapatite formation on the sample surface and it is concluded that the best condition is biomimetic treatment with 5M alkali treatment and heat treatment at 80 ° C for 72 hours
