1. A Nodal-iterative Technique for Criticality Calculations in Multigroup Neutron Diffusion Models
ABSTRACT In this work, a nodal and iterative technique to evaluate the effective multiplication factor as well as the neutron flux, in multigroup diffusion problems, is presented. An iterative scheme, similar to the source iteration method, is implemented to decouple the system of differential equations which is the fundamental mathematical model. Then, anal

3. Do cytomegalovirus infections affect the daratumumab treatment course in multiple myeloma patients? - Literature review
ABSTRACT Introduction Multiple myeloma is a progressive and incurable hematological disease characterized by disordered and clonal multiplication of plasmacytes in the bone marrow. The main clinical manifestations are caused by the presence of neoplastic cells in bone tissue, as well as the excessive production of immunoglobulins and normal humoral immunity

4. DISINFECTION PROTOCOL AND IN VITRO GERMINATION OF SEEDS OF Dalbergia nigra
ABSTRACT The Atlantic Forest is a biome that has suffered anthropic actions, such as the extraction of hardwood, which can lead to the extinction of endemic species of great economic and ecological value, such as Dalbergia nigra. In this perspective, large-scale multiplication studies are necessary to contribute to the conservation of this species. The objec

5. Reaction of weeds, found in vegetable production areas, to root-knot nematodes Meloidogyne incognita and M. enterolobii
RESUMO Os nematoides-das-galhas causam muitos prejuízos às lavouras de hortaliças no Brasil, além de possuírem grande gama de plantas hospedeiras, incluindo as plantas daninhas. Estas podem manter o inóculo ou mesmo favorecer a multiplicação desses nematoides. Diante do exposto, objetivou-se com esse trabalho avaliar a reação de espécies seleciona

6. Physalis angulata L. propagation in vitro
ABSTRACT Physalis angulata L. is a plant with great fruit production potential, mainly in family farms, due to its versatility and valuable products such as jellies and juice concentrates. The aim of the present study is to evaluate the effect of two cytokines - i.e., plant growth regulators 6- benzylaminopurine (BAP) and kinetin (KIN) -, in association, or

7. Techniques for prevention and control of poisoning by sodium monofluoroacetate (MFA)-containing plants in ruminants
RESUMO: As plantas que contém monofluoroacetato (MFA) causam morte súbita associada ao exercício em ruminantes, e são responsáveis por grandes perdas na pecuária brasileira, estimadas em 500.000 mortes de bovinos anualmente. O controle e tratamento desse tipo de intoxicação, na maioria das vezes, não apresenta eficiência, visto que a evolução da

8. Influence of the host diet on the performance of Doryctobracon areolatus (Hymenoptera: Braconidae)
Resumo O custo adaptativo de parasitoides é geralmente influenciado pela qualidade do hospedeiro. Nós avaliamos parâmetros de desenvolvimento do parasitoide Doryctobracon areolatus (Hymenoptera: Braconidae) em larvas de Anastrepha fraterculus (Diptera: Tephritidae) criadas em dieta artificial com diferentes fontes proteicas. Larvas de A. fraterculus foram

9. El pensamiento multiplicativo de niños del pueblo indígena shipibo-konibo de Ucayali: una perspectiva piagetiana
Abstract The objective of this study was to identify and describe levels of multiplicative thinking in a group of Shipibo-Konibo children from the Ucayali region, in the Peruvian Amazon rainforest. Fourteen elementary school students from two Shipibo-Konibo communities, boys and girls aged between 7 and 12 years old, participated in the study. They were eval

10. Meta-topolin: an alternative for the prevention of oxidative stress in sugarcane micropropagation
RESUMO A influência de duas citocininas aromáticas (CKs), 6-benzilaminopurina (BAP) e meta-topolina (mT) na propagação in vitro e no metabolismo redox da cana-de-açúcar (Saccharum spp., variedade RB98710) foi investigada. As plantas foram cultivadas em meio Murashige e Skoog (MS) suplementado com mT (5 µmol.L-1) ou BAP (5 ou 6,66 µmol.L-1) por 40 dia

12. Diagnostic fingerprints ISSR/SSR for tropical leguminous species Stylosanthes capitata and Stylosanthes macrocephala
ABSTRACT: Stylosanthes capitata Vogel and Stylosanthes macrocephala M.B.Ferreira & Sousa Costa are two forage leguminous species of agronomic importance for animal husbandry in tropical environments. The physical mixture of both species (80 % S. capitata and 20 % S. macrocephala) comprises the commercial cultivar “Estilosantes Campo Grande”. However, pro
