TERCEIRIZAÇÃO DAS ATIVIDADES FINS EM EMPRESAS PRIVADAS: REFLEXOS DA PRECARIZAÇÃO DO TRABALHO
Com o avanço expressivo do capitalismo nas últimas décadas, os métodos de trabalho sofreram bruscas modificações. A terceirização surge nesse contexto e, com suas espécies contratuais enxutas, acaba por tornar precária a relação de trabalho. Quando analisada perante os princÃpios do direito do trabalho, é possÃvel perceber as inconsistências e as intenções perversas dessa forma de subcontratação. Toda a construção do pleno emprego como sendo uma garantia mÃnima de estabilidade conferida ao trabalhador, se vê em risco com a verificação da terceirização. A regra do contrato de trabalho permanente parece já não estar tão protegida assim após as alterações feitas na Lei 6.019/74 através da Lei 13.429/2017.O presente trabalho localiza-se num cenário de incertezas, buscando estudar e compreender as possÃveis nuances do fenômeno terceirizador após ter sido regulamentado, isso se faz, ao analisar algumas formas de precarização já conhecidas causadas pela terceirização.Palavras-chave: Terceirização.

Fermentation Profile of Signal Grass Silages Intercropped With Calopo or Fertilized With Nitrogen and Treated With Microbial Inoculant
Tropical grasses have characteristics that allow the occurrence of undesirable fermentations resulting in low quality silage. Inoculants can improve silage quality. Fermentation profile and microbial population of signal grass silages under four management (M), with and without microbial inoculant, were evaluated. The experiment was carried out in a 4 × 2 factorial scheme, with silages of signal grass managed without N application (control, 0N), fertilized with 50 kg ha-1 of N (50N), fertilized with 100 kg ha-1 of N (100N), or signal grassintercropped with calopo (Calopogonium mucunoides D.) (LEG), with inoculant (I) andwithout inoculant (WI), in a randomized block design, with two replications of area and two replications of treatment per block. Analysis of pH, organic acids, ethanol, ammonia nitrogen, and microbial populations were performed in the silages. The use of inoculant reduced the acetic acid concentration in the 100N treatment silages (20.1 to 12.8 g kg-1 of DM). The lowest concentration of butyric acid (BA) (2.33 g kg-1 DM) was observed in signal grass silage fertilized with 100 kg of N, without inoculant. In inoculated silages, the treatments 50N and LEG provided lower concentrations of BA in relation to the control. Silage from the uninoculated 50N treatment had the lowest concentration of N-NH3 in relation to the other silages. The lactic acid bacteria (LAB) population was not affected by the factors studied. The inoculant provided a reduction in the population of enterobacteria. No mold and yeast populations were detected in the silages investigated. Signal grass silage fertilized with N or intercropped with calopo, with microbial inoculant, had better fermentative characteristics and could be an option for strategic management of pastures in tropical areas
Sex Reversal Syndrome in an Egyptian Arabian Horse Detected Using Genomic Data – A case report
A 4-year-old Straight Egyptian Arabian horse was evaluated in 2016 due to a malformation of external genitalia and male sexual behavior. On physical examination, small teats in the inguinal area and a rudi- mentary penis-like structure surrounded by a clitoral fossa could be seen. There was no evidence of vulva and vaginal canal. A stallion like behavior was observed, especially in the presence of mares in heat, when the animal was excited and aggressive and had erection of the penis-like structure. Blood samples were collected for two purposes: hormonal (testosterone and estradiol plasma concentration analyses) and genetic (cytogenetic and molecular analysis). The karyotype showed 32 pairs of chromosomes in all cells (2n = 64) including 14 and 18 pairs of metacentric and acrocentric chromosomes respectively, in agreement with a presumptive 64, XX complement. This result agree with STR and SNP molecular analysis, which also ruled out the possibility of hematopoietic chimerism. In addition, SNP genotyping showed no numerical chromosomal aberrations or large deletions or duplications, that can be linked to the phenotype in any autosome, nor numerical chromosomal abnormalities in the father and mother of the horse analyzed. In conclusion, we determined that the animal in the present study is a male pseudo- hermaphrodite.Fil: Oliveira Nogueira, Pedro Paulo.
