Objective:To evaluate the larvicidal efficacy of eight volatile components of essential oils against 3rd instar larvae of Anopheles gambiae ***:Larvicidal effects of each compound were evaluated in both laboratory and semi-field *** solution was prepared and serial dilutions were made in six concentrations for each compound.A total of 20 larvae were exposed to larvicides for each replicate and monitored at intervals of 12,24,48 and 72 *** monitoring was done on basis of dead and live larvae in all ***:All assayed compounds were larvicides and presented varying degrees of larval toxicity,with LC50 values ranging from 1.28 to 1 938.92 mg/L depending on the treatment time(12,24,48 or 72 h).(-)-Perillyl alcohol presented the strongest larvicidal activity towards Anopheles gambiae larvae,with LC_(50) values of 73.60,18.36,1.72 and1.28 mg/L after 12,24,48 and 72 h of exposure,*** next strongest were(-)-isopulegol(LC_(50)= 135.10,49.39,34.39 and 20.22 mg/L) and(-)-carvone epoxide(LC_(50)= 168.86,124.74,80.84 and 23.46 mg/L).After 12,24 and 48 h of treatment,hydroxydihydrocarvone was the least toxic compound,with LC_(50) values of 1 938.92,1 172.18 and 401.03 mg/L,***:The data obtained in this study suggest that all evaluated monoterpenes,especially(-)-perillyl alcohol,have remarkable larvicidal effects and may be considered as potential sources for the development of suitable natural larvicides for mosquito management *** small-scale field trials should be conducted.

Oxytetracycline Water Contamination Treated with Biocarbon TiO2 and Solar Photodecomposition

引用

Journal of Agricultural Chemistry and Environment 2020年第4期9卷 299-313页

作者： Nilce Ortiz Izabela Rodrigues cerqueira lima Azevedo Marília Guerino Vieira Fernanda Maichin Lucia Nascimento Institute for Nuclear and Energy Research—IPEN S&#227 o Paulo SP Brasil

Reliable data of antibiotic use and environmental discharge as veterinary medicine are essential to help countries raise awareness of the appropriate use, control, and correct water release. The first approach is to change the regulatory framework based on consuming information, use policy, and discharge laws. The important research contribution is a novel water treatment process to treat, remove, and reduce antibiotic concentration in discharged water, mainly those used in the animal protein industry. The low particle biochar added during the titanium isopropoxide hydrolysis reduces the titanium dioxide (TiO2) agglomerates and promotes the adsorption surface process. Such improved catalyst material enhances the solar decomposition efficiency to 93% from original oxytetracycline with better correspondence with the Elovich kinetics, intraparticle diffusion, R-P isotherm, and Langmuir-Hinshelwood model.

Intake,digestibility and nitrogen utilization in cattle fed tropical forage and supplemented with protein in the rumen,abomasum,or both

引用

Journal of Animal Science and Biotechnology 2016年第4期7卷 544-553页

作者： Luana Marta de Almeida Rufino Edenio detmann Daianyíris Gomes William lima Santiago dos Reis Erick Darlisson Batista Sebastiao de Campos Valadares Filho Mário Fonseca Paulino department of Animal Science Universidade Federal de Viaosa department of Animal Science Universidade Federal Rural da Amaznia

Background： There is little information in the tropics with regard the comparative understanding of how an increased nitrogen supply in the rumen or in the intestines affects efficiency of nitrogen utilization in cattle. This study evaluated the effects of supplementation with nitrogenous compounds in the rumen, abomasum, or both on intake, digestibility and the characteristics of nitrogen utilization in cattle fed tropical forage. Four rumen- and abomasum-fistulated Nellore bulls （227 ± 11 kg） were used. Four treatments were evaluated： control, ruminal supplementation （230 g/d of supplemental protein in the rumen）, abomasal supplementation （230 g/d of supplemental protein in the abomasum）, and ruminal and abomasal supplementation （115 g/d protein in both the rumen and the abomasum）. The basal forage diet consisted of Tifton 85 hay with a crude protein （CP） level of 78.4 g/kg dry matter. Casein was used as a supplement. The experiment was conducted using a 4 x 4 Latin square. Results： There were no differences between the treatments （P 〉 0.10） with regard to forage intake. The intake and tota digestibility of CP increased （P 〈 0.01） with supplementation. The nitrogen balance in the body increased （P 〈 0.01） and muscle protein mobilization decreased （P 〈 0.01） with supplementation, regardless of the supplementation site. The efficiency of nitrogen utilization did not differ among the treatments （P 〉 0.10）. Conclusions： The supplementation of cattle fed tropical forage with protein in the rumen, abomasum, or both similarly increased the nitrogen accretion in animal, which reflects improvements on nitrogen status in animal body.

Efficient Incremental Maintenance of Frequent Patterns with FP-Tree

Journal of Computer Science & Technology 2004年第6期19卷 876-884页

Mining frequent patterns has been studied popularly in data mining area. However, little work has been done on mining patterns when the database has an influx of fresh data constantly. In these dynamic scenarios, efficient maintenance of the discovered patterns is crucial. Most existing methods need to scan the entire database repeatedly, which is an obvious disadvantage. In this paper, an efficient incremental mining algorithm, Incremental-Mining (IM), is proposed for maintenance of the frequent patterns when incremental data come. Based on the frequent pattern tree (FP-tree) structure, IM gives a way to make the most of the things from the previous mining process, and requires scanning the original data once at most. Furthermore, IM can identify directly the differential set of frequent patterns, which may be more informative to users. Moreover, IM can deal with changing thresholds as well as changing data, thus provide a full maintenance scheme. IM has been implemented and the performance study shows it outperforms three other incremental algorithms: FUP, DB-tree and re-running frequent pattern growth (FP-growth).

The objectives of this study were to apply statistical techniques to discriminate fertilization treatments of Eremanthus erythropappus（DC.） Mac *** autoregressive modeling, and to develop individual tree models for diameter and crown area（CA） projection to define management strategies for candeia plantations subjected to different fertilization treatments. This is an important tree species originating from the Brazilian Atlantic Rain forest and Savannah biomes, intensively used in the cosmetic industry. Nonetheless, to date, research has not addressed the management of natural stands or plantations of the species. Our experiment was located in Baependi, Minas Gerais, Brazil, and comprised of four randomized blocks and 13 treatments. The treatments consisted of 12 different regimes of fertilization plus a control. Each sample plot was composed of 50 plants plus two border plants in a planting spacing of 2.5 9 2.0 m and undergoing pruning at 5 and 6 years of age. Starting in the second year, total tree height（H） and circumference（at 1.30 m from the ground or breast height, CBH） were measured every 6 months. Starting in the fifth year CA was measured. Tree growth varied by fertilization *** were detected by using an autoregressive approach, considering that standard statistical methods were not powerful enough to detect significant *** growth groups were formed, and maximum growth was obtained for treatment 10（NPK, 8-28-16）. Management guidelines are provided based on individual tree models for different fertilization levels.
