3-Phenoxybenzoic acid is an intermediate in the degradation of several pyrethroid insecticides in soil. Two pseudomonads were isolated together on vitamin-supplemented nutrient agar from 3-phenoxybenzoate enrichment of an agricultural soil. One isolate, designated 13b, grew on 3-phenoxybenzoate in mineral salts medium producing stoichiometric amounts of phenol. It degraded 3-[phenoxy-14C(U)]phenoxybenzoate to [14C(U)]phenol and did not assimilate any 14C from this molecule. It metabolized [carboxyl-14C]3-phenoxybenzoate but not [14C(U)]phenol. It also produced 4-chlorophenol and p-cresol from 3-(4-chlorophenoxy)benzoate and 3-(4-methylphenoxy)benzoate, respectively. This indicated that isolate 13b transformed the benzoate but not the phenoxy moiety of 3-phenoxybenzoate. The second isolate, designated 13a, did not metabolize 3-phenoxybenzoate but grew on and mineralized phenol. Incubation of 3-phenoxybenzoate with isolates 13a and 13b together resulted in the degradation of both aromatic nuclei. Key words: 3-phenoxybenzoate, bacterial degradation, mineralization, pyrethroid.

Intramolecular Amidation

To reveal the scope of the syntheses of 3-aryl-2-quinolinones from 2-nitro-α-phenylcinnamic acids, the isomerization of (E)-2-amino-α-phenylcinnamic acids was studied. The results showed that (E)-2-amino-α-phenylcinnamic acids were isomerized to its (Z)-forms under sunlight in organic solvents. The reaction temperature and the functional groups at both phenyl rings have no effect on the isomerization of (E)-2-amino-α-phenylcinnamic acids and the following intramolecular spontaneous amidation of (Z)-2-amino-α-phenylcinnamic acids. Various 3-aryl-2-quinolinones prepared in high total yields indicated that the syntheses of 3-aryl-2-quinolinones from Perkin condensation products 2-nitro-α-phenylcinnamic acids via reduction, sunlight-induced isomerization of (E)-2-amino-α-phenylcinnamic acids, and the following intramolecular amidation is an efficient procedure. Key words: 3-aryl-2-quinolinones, isomerization, amidation.

Para Determinar

Os artigos continuam sendo a principal maneira de divulgação científica nos meios especializados. Tem sido observado que muitos dos artigos submetidos à Horticultura Brasileira seguem as normas para publicação, mas apresentam problemas em seu formato. Os problemas mais comuns são sua extensão (muito longos ou curtos), título inadequado, resumo e "abstract" diferentes em tamanho e conteúdo, falta de uma proporção entre as divisões do artigo e excesso de tabelas e figuras ou com tamanho inadequado. Para determinar-se o artigo "ideal" em termos de tamanho e formato foi realizado um levantamento em dez artigos publicados na Horticultura Brasileira, Fitopatologia Brasileira, HortScience e Plant Disease de 2000 e 2001. Como resultado, obteve-se as seguintes médias: título, 14 palavras; número de autores, 4; número de instituições dos autores, 2; número de palavras-chave, 3; número de key-words, 3; resumo, 200 palavras; abstract, 202; introdução, 470 palavras; material e métodos, 640 palavras; resultados e discussão, 890 palavras; número de artigos citados, 24; número de tabelas e figuras, 2-3; número de páginas impressas, 5. Esta proporção pode servir como um guia e um modelo em relação ao tamanho e formato do artigo. A apresentação adequada de um artigo, aliada ao seu conteúdo e qualidade científica, podem acelerar sua tramitação e publicação, além de agradar aos leitores.

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the digestive tract (1%). These tumors express the CD 117 in 95% of cases. The stomach is the preferential localization (70%). Diagnosis is difficult and sometimes late. Progress of imaging has greatly improved the management and the prognosis. Computed tomography (CT) is the gold standard for diagnosis, staging, and treatment follow-up. The increasing recognition of GIST’s histopathology and the prolonged survival revealed some suggestive imaging aspects. Key words: gastro-intestinal stromal tumors; computed tomography; diagnosis

Five phosphorus rates (0, 5, 10, 20 and 30 kg P/ha) were tested with four rice genotypes in Boro (BRRI dhan36, BRRI dhan45, EH1 and EH2) and T. Aman (BRRI dhan30, BRRI dhan49, EH1 and EH2) season. Phosphorus rates did not influence grain yield irrespective of varieties in T. Aman season while in Boro season P response was observed among the P rates. Application of P @ 10 kg/ha significantly increased the grain yield. But when P was applied @ 20 and 30 kg P/ha, the grain yield difference was not significant. The optimum and economic rate of P for T. Aman was 20 kg P/ha but in Boro rice the optimum and economic doses of P were 22 and 30 kg/ha, respectively. Hybrid entries (EH1 and EH2) used P more efficiently than inbred varieties. A negative P balance was observed up to 10 kg P/ha.

A Value

One indicator of the success ofeducation in the level of classroom learning is when a lecturer is able to build student learning achievement and will be more successful if this achievement can be increased if their attendance is above 80% (minimum 10 times attendance from 12 meetings). If the students can be grown discipline and provided a decent campus facilities, then as difficult as any lecture material or learning process that followed by they undoubtedly will live with feelings of joy, even they will feel sad if that day lecturer could not come because there is a need outside campus.There are four stages of appraisal that apply to each student for each course taken include (1) attendance of 10% (2) Task 20% (3) 30% Semester Exam (UTS) and (4) Final Exam Semester. (UAS) 40%. The writer as a lecturer tries to cultivate motivation to learn from the beginning, in addition to always communicate actively with students who follow the lecture also monitor attendance and assignment, each completed college is always given the practice / tasks are directly given the value, usually given the task quite easily so they can get a value of 100, even if there is a miscalculation, they are still given the opportunity to fix the error so that eventually get a value of 100. With the value of this 100, their motivation to grow and even grow in such a way that spur them to diligent lectures.The difficulty level of the task is balanced with the lecture, the longer it is raised so as to reach the maximum average level of student ability at the end of the lecture meeting...This research reveals that there is no a significant correlation between student achievement to discipline presence of student/mahasiswa with campus facilities. The analyzing was taken from an answer of 55 students who were randomly selected as respondents by filling out the Questionaire that was distributed to them. Key words : achievement, attendance, discipline, campus facility
