This study aimed to show that the physicochemical proprieties obtained by Fourier transform infrared spectroscopy （FTIR）, thermogravimetry （TG）, and scanning electronic microscopy （SEM） can be useful tools for evaluating the quality of active pharmaceutical ingredients （APIs） and pharmaceutical products. In addition, a simple, sensitive, and efficient method employing HPLC-DAD was developed for simulta- neous determination of lidocaine （LID）, ciprofloxacin （CFX） and enrofloxacin （EFX） in raw materials and in veterinary pharmaceutical formulations. Compounds were separated using a Gemini Cm （250 mm×4.6 mm, 5μm） Phenomenex column, at a temperature of 25℃, with a mobile phase containing 10 mM of phosphoric acid （pH 3.29）： acetonitrile （85.7：14.3, v/v） and a flow rate of 1.5 mL/min. Physicochemical characterization by TG, FTIR, and SEM of raw materials of LID, CFX, and EFX provided information useful for the evaluation, differentiation, and qualification of raw materials. Finally, the HPLC method was proved to be useful for evaluation of raw material and finished products, besides satisfying the need for an analytical method that allows simultaneous determination of EFX, CFX, and LID, which can also be extended to other matrices and applications.

Efficiency in Teaching Speaker and Listener Repertoires:Comparing Three Instructional Sequences in Autistic Children

Previous studies have investigated the efficiency in teaching listener and speaker repertoires in children diagnosed with autism spectrum disorder(ASD).Some investigations focused on listener responding by function,feature,and class(LRFFC)and intraverbal by function,feature,and class(FFC).For some children,teaching intraverbal FFC was more efficient because it resulted in a better emergence effect of a related untaught repertoire(LRFFC).For other children,teaching LRFFC along with tacting pictures was more efficient,resulting in a better emergence effect of a related untaught repertoire(intraverbal FFC).In these cases,it is not clear whether the tact increased the efficiency of LRFFC training because a comparison with a condition in which tacts were not required was not *** investigation consisted of a replication with two children diagnosed with *** instructional sequences were compared:teaching LRFFC-probing intraverbal;teaching LRFFC+tacts-probing intraverbal;teaching intraverbal-probing *** a child,all sequences were equally efficient because all related untaught repertoires emerged without ***,the acquisition of intraverbals during training occurred with *** the case of the second child,the most efficient sequence consisted of teaching intraverbals,resulting in the emergence of LRFFC without *** both cases of teaching LRFFC,the emergence of related intraverbals was partial and acquisition of the trained repertoires occurred with *** case that did not demand tact responses was slightly more *** were discussed in the sense that the best instructional sequence may vary from learner to learner.

Analysis of Tracheal Secretion in Healthy Horses Undergoing a Vaquejada Simulation Test

Open Journal of Veterinary Medicine 2014年第10期4卷 232-238页

This study aimed to evaluate the occurrence of EIPH in vaquejada horses via endoscopy and tracheal lavage and citology. We used eight Quarter-mile horses that usually perform at vaquejadas. Clinical examination was carried out before the race. After the race, endoscopy and tracheal lavage with 20 ml of saline via the service channel of the endoscope were performed. The samples were sent to the laboratory for processing and confection of the slides. Of the eight horses (four pull and four helper horses), six had hemosiderophages in their tracheal aspirates, confirming the existence of pulmonary hemorrhage after exercise. No difference was observed between the analyzed parameters between the two groups of vaquejada horses (P > 0.05). Tracheal lavage and endoscopy can be used for evaluating this important disease in animal athletes.

Changes in Soil Carbon Stocks under Integrated Crop-Livestock-Forest System in the Brazilian Amazon Region

引用

Agricultural Sciences 2017年第9期8卷 904-913页

作者： Marcela C.G.da Conceicao Eduardo S.matos Edison D.Bidone Renato de A.R.Rodrigues Renato C.cordeiro Universidade Federal Fluminense NiteróiBrazil Embrapa Agrossilvipastoril SinopBrazil Embrapa Solos Rio de JaneiroBrazil

Several studies indicate that the use of integrated production systems, such as integrated crop-livestock-forest systems (ICLF), improves the quality of the soil and consequently the sequestration of organic carbon in the soil. In this way, this work aims to evaluate the carbon stocks in soil under different management systems in the Cerrado/Amazonia transition zone, namely: ICLF, no-tillage, pasture and eucalyptus plantation. For this, two soil samplings were done in 2011 and 2014, in the 0 - 5, 5 - 10 and 10 - 30 cm layers. Soil carbon and nitrogen stocks were analyzed. ICLF system was the treatment that obtained the highest percentage of carbon gain (7.8%) after three years of establishment which represents to an increase of 5.5 Mg·ha-1. Management systems, such as ICLF, with minimal soil disturbance combined with crop rotations that contribute to the quantity and quality of residues input, increase soil organic matter content. Carbon stock data show the potential of ICLF systems to increase soil carbon stocks.

Growth and Visual Symptoms of Nutrients Deficiency in Mangosteens(Garcinia mangostana L.)

American Journal of Plant Sciences 2018年第5期9卷 1014-1028页

The aims of study were to evaluate growth and characterize the visual symptoms of macronutrient and micronutrient deficiencies in mangosteens. The seedlings were cultivated in nutritive solution containing all required macronutrient and micronutrients and in solutions with omission of N, P, K, Ca, Mg, S, B, Cu, Fe, Mn, and Zn, using the missing element technique. The experimental design was completely randomized with five replicates and twelve treatments. Symptoms of nutrient deficiency were accompanied by photographic records and described from beginning until complete definition, in which the plants were collected. Growth was evaluated through of dry mass production and nutrient contents. Nutrients omissions resulted in morphological alterations, characteristic symptoms of nutritional deficiency, promoted the reduction in dry mass production in plant, in which the Fe was most limiting, followed by N, and S. Macronutrients and micronutrients contents, without deficiencies (complete treatment) and deficient in mangosteen leaves were respectively: N (16.4 and 12.5 g kg-1);P (1.1 and 0.2 g kg-1);K (10.2 and 8.1 g kg-1);Ca (6.7 and 1.9 g kg-1);Mg (1.1 and 0.1 g kg-1);S (3.0 and 2.2 g kg-1);B (20 and 16 mg kg-1);Cu (7 and 3 mg kg-1);Fe (266 and 86 mg kg-1);Mn (58 and 17 mg kg-1). The decreasing order in appearance of visual symptoms of deficiency was N > S > K > B > Ca > P > Mg > Mn > Cu > Zn.
