Biochemical and Mitochondrial Changes Induced by Cd, Fe and Zn in Limnodrillus hoffmeisteri International Journal of Morphology
Grajeda y Ortega,María de los Angeles; Ortiz Ordoñez,Esperanza; Favari,Liliana; Shibayama,Mineko; Silva Olivares,Angélica; López López,Eugenia.
The effects of sublethal concentrations of cadmium (0.64 µg/L), iron (0.043 mg/L) and zinc (0.31 mg/L) and a mixture of these metals on succinate dehydrogenase (SD) and alkaline phosphatase (AP) activity and on structural changes in the mitochondria of epithelium cells of the digestive tract were examined in the oligochaete Limnodrillus hoffmeisteri after 96 h of exposure in artificial sediments. SD activity was significantly inhibited, particularly in treatments with Cd alone (92.57%), while AP increased its activity with Cd alone (73.23%). However, when this metal was mixed with Fe and Zn, the inhibition of SD activity was lower (67.82%) than with Cd alone, showing an antagonistic effect and AP increased its activity (73.26%). Mitochondria were...

Crystal morphology of binary and ternary mixtures of hydrogenated fats and soybean oil BABT
Simões,Ilka Sumiyoshi; Gioielli,Luiz Antonio.
The objective of this study was to verify the influence of temperature on crystallization of binary and ternary mixtures of two hydrogenated fats and soybean oil, by polarized light microscopy at temperatures of 30° C, 35° C, and 40° C. The types of crystals observed were spherulites type A, and B and the polymorphic forms were ß , and ß -prime. The soybean oil does not contribute statistically to total area or maximum diameter of the crystals. At 35° C the positive relative coefficients to the interactions presented, in general, absolute values higher than the negative ones, pointing that the crystals were larger than what could be expected, if there was no interaction among the components. At 40° C the negative relative coefficients revealed, in general,...

Evaluation of almond shell as a culture substratefor ornamental plants. II. Ficus benjamina: (with 3 tables & 2 figures) Phyton
Lao,MT; Jiménez,S.
Some technical and economic problems currently limit the use of substrates. The main problems include the lack of reciprocal adaptation of the cultivation technics and the substrate,the possible presence of pathogens, and the cost involved. To these we must add the ecological problems of the extraction areas, since there are no short-term renewable resources, especially in peat, the classic substrate. This has motivated the search for substitutes, especially amongst indigenous materials and those easily obtainable locally, such straws cereals, rice husk and cork residuous. The use of these substrates should be evaluated agronomically for: physical, chemical and cultural properties. The characterisation and use of almond shell (Prunus dulcis) as a...

Joint effects of nine antidepressants on Raphidocelis subcapitata and Skeletonema marinoi : a matter of amine functional groups ArchiMer
Minguez, Laetitia; Bureau, Ronan; Halm-lemeille, Marie-pierre.
Antidepressants are among the most prescribed pharmaceuticals throughout the world. Their presence has already been detected in several aquatic ecosystems worldwide and their effects on non-target organisms justify the growing concern of both the public and regulatory authorities. These emerging pollutants do not occur as isolated compounds but rather as multi-component mixtures, which may lead to increased adverse effects compared to individual compounds. Freshwater and marine algae seem particularly sensitive to pharmaceuticals, including antidepressants. Studies assessing the toxicity of antidepressant mixture to algae focused mainly on binary mixtures of selective serotonin reuptake inhibitors. In the present experiment, the freshwater algae...

Statistical procedure for the composition of a sensory panel of blends of coffee with different qualities using the distribution of the extremes of the highest scores Agronomy
Cirillo, Marcelo Ângelo; Ramos, Mariana Figueira; Borém, Flávio Meira; Miranda, Felipe Mesquita de; Ribeiro, Diego Egídio; Menezes, Fortunato Silva de.
The identification and interpretation of discrepant observations in sensory experiments are difficult to implement since the external effects are associated with the individual consumer. This fact becomes more relevant in experiments that involve blends, which scrutinize coffees with different qualities, varieties, origins, and forms of processing and preparation. This work proposes a statistical procedure that facilitates the identification of outliers while also evaluating the discriminatory powers of a sensory panel concerning the differentiation of pure blends and coffees. For this purpose, four experiments were performed that tested coffees with different qualities and varieties. The results suggest that the statistical procedure proposed in this work...

每穴種植株數對同質與異質大豆族群生育之影響 Taiwan Agricultural Research Institute
林順福; 詹國連; 魏趨開; S.F. Lin;K.L. Chan;C.K. Wey.
[[abstract]]由於本省大豆種植方式普遍為每穴種植二株,可能造成同穴植株間之競爭壓力,因而影響產量及育種選拔效果,又因兼顧雜交早期分離世代為不同基因型之異質族群,後期品系世代之同一試區或系行為相同基因型之同質族群,故本試驗針對此種植株間競爭壓力改變及早後期世代之不同遺傳背景兩大要素進行探討,以供栽培及育種選拔參考,試驗結果: 1. 同質與異質族群有顯著差異之性狀為植株乾物重及粒數,而產量性狀則未有顯著差異,可知早期與後期世代之植株間競爭方式對產量選拔未有顯著影響。 2. 每穴種植株數所影響性狀與穴距相同,每穴種植二株較每穴種植一株具有顯著較高植株、較少分枝數、較低植株乾物重、較少粒數、較大之收穫指數、較低單株產量及較高小區產量。 3. 在單位面積一定株數下,每穴株數與穴距對產量之影響未有顯著差異,故每穴種植二株之植株競爭壓力,可因穴距加大之緩衝,而對早期或後期世代之育種選拔無顯著之影響。
