ABSTRACT The present study focuses on the investigation of both near-surface and vertical variability of carbon monoxide (CO) concentrations and their potential sources obtained from both in situ and satellite Measurements of Pollution in the Troposphere (MOPITT) over a semiarid region (Anantapur, India) from January 2016 to December 2017. The diurnal variation of CO shows sharp morning (07:00-09:00 LT) and evening (07:00-09:00 LT) peaks associated to local anthropogenic activities as well as the impact of the mixed layer height, and low concentrations during daytime (12:00-15:00 LT). The low levels during afternoon hours may be due to the increase of the mixed layer height and the decrease of anthropogenic sources. The seasonal mean CO showed no obvious variation, with highest levels observed in winter (329 ± 52 ppbv), followed by the pre-monsoon (327 ± 57 ppbv), post-monsoon (234 ± 36 ppbv) and monsoon (192 ± 22 ppbv). The high levels of CO during the winter are attributed to increased emissions from anthropogenic sources and a shallow mixed layer height. The vertical distribution of CO showed secondary peaks at high-pressure levels (300-200 hPa) during winter, pre-monsoon, and post-monsoon, which indicates CO transport from different source regions. These findings are reasonably confirmed through the air mass Concentrated Weighted Trajectory (CWT) analysis obtained from the Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model. This study suggests that except for the monsoon, air masses transported from Indo-Gangetic Basin region also contribute to the enhancement of CO concentrations at the receptor site.

RESUMEN El presente estudio se enfoca a la investigación de la variabilidad tanto vertical como cercana a la superficie de las concentraciones de monóxido carbono (CO), así como de sus fuentes potenciales, obtenidas tanto in situ como a partir de datos satelitales del instrumento MOPITT (Measurement of Pollution in the Troposphere) sobre una región semiárida (Anantapur, India), de enero de 2016 a diciembre de 2017. La variación diurna del CO muestra picos pronunciados durante la mañana (de 07:00 a 09:00 horas) y la tarde (de 19:00 a 21:00 horas) asociados con actividades antrópicas locales y el impacto de la altura de la capa de mezcla, así como bajas concentraciones en el día (12:00 a 15:00 horas). Los bajos niveles durante las horas de la tarde pueden deberse al incremento de la altura de la capa de mezcla y al decremento de las fuentes antrópicas. La media estacional del CO no mostró variaciones evidentes, con los niveles más altos observados durante el invierno (329 ± 52 ppbv), seguido por el premonzón (327 ± 57 ppbv), el postmonzón (234 ± 36 ppbv) y el monzón (192 ± 22 ppbv). Los niveles altos de CO observados durante el invierno se atribuyen a emisiones antrópicas y a la escasa altura de la capa de mezcla. La distribución vertical del CO mostró picos secundarios en presencia de niveles de presión altos (300-200 hPa) durante el invierno, el premonzón y el postmonzón, lo cual indica que hay transporte desde diferentes fuentes regionales. El análisis de la concentración ponderada de la trayectoria (CWT, por sus siglas en inglés) de la masa de aire, obtenida a partir del modelo HYSPLIT (Hybrid Single Particle Lagrangian Integrated Trajectory) confirma de manera razonable estos hallazgos. El presente estudio sugiere que, con excepción de la época del monzón, las masas de aire transportadas desde la región de la cuenca indogangética también contribuyen al incremento de las concentraciones de CO en el sitio receptor.

Um novo método isocrático, rápido e simples da cromatografia líquida de alta performance (HPLC) de fase normal quiral foi desenvolvido e validado para a separação enantiomérica do ácido (S)-10-hidroxicamptotecin (10 HCTN), ((4S)-4-etil-4,9-dihidro-1H-pirano [3',4':6,7] indolizina [1,2-b] quinolina-3, 14 (4H, 12H)-diona), um fármaco anti-cancerígeno. Os enantiômeros de 10 HCTN foram separados em uma coluna Chiralpak IC (fase estacionária quiral derivada de polissacarídeo imobilizado), utilizando uma fase móvel que consiste de n-hexano:etanol (50:50 v/v) em uma vazão de 1,0 mL min-1. A resolução entre os dois enantiômeros foi superior a 3 usando o método otimizado. O método desenvolvido foi validado e mostrou serrobusto, exato, enantiosseletivo, preciso e adequado para a determinação quantitativa do enantiômero-(R) tanto na matéria prima quanto no fármaco.

A new and simple, rapid, isocratic, normal phase chiral high performance liquid chromatography (HPLC) method was developed and validated for the enantiomeric separation of (S)-10-hydroxycamptothecin (10-HCTN), ((4S)-4-ethyl-4,9-dihydroxy-1H-pyrano[3',4':6,7]indolizino[1,2-b] quinoline-3,14(4H,12H)-dione), an anti-cancer drug substance. The enantiomers of 10-HCTN were resolved on a Chiralpak IC (immobilized polysaccharide chiral stationary phase) column using a mobile phase consisting of n-hexane:ethanol (50:50 v/v) at a flow rate of 1.0 mL min-1. The resolution between both enantiomers was greater than 3 in the optimized method. The developed method was extensively validated and proved to be robust, enantioselective, accurate, precise, and suitable for quantitative determination of (R)-enantiomer in bulk drug substance and product.

A novel approach to design Multiple Function Antenna (MFA) arrays using Artificial Neural Networks is suggested. A planar array with uniform current excitations which can generate different beam widths and gains is designed using Artificial Neural Networks. The desired beam width, gain and number of elements are given as input to the neural network. The output of the neural network is the current excitations in the form ON/OFF state of the array. Radial Basis Function Neural Network (RBFNN) is initially trained with the input-output data pairs and tested. The network showed 98% high success rate.

O extrato metanólico total de Leucas cephalotes foi submetido à triagem para as atividades antioxidante in vitro (utilizando o método DPPH), analgésica (utilizando teste da placa quente, em camundongos) e antiinflamatória (utilizando teste de edema da pata de rato), nas doses de 200 e 400 mg/kg. O extrato metanólico de Leucas cephalotes (MELC) inativou radicais difenil picril hidrazila (DPPH) de forma dose-dependente. O IC50 para essa atividade foi de 421,3 µg/mL. Observou-se atividade analgésica significativa (p<0,0005) a 60 minutos, com 200 mg/kg, e, com 400 mg/kg, observou-se atividade máxima. A resposta antiinflamatória máxima foi produzida, respectivamente, em 3 h e 2 h, com doses de 200 e 400 mg/kg. Estes resultados sugerem que o extrato metanólico de Leucas cephalotes apresenta efeitos analgésico e antiinflamatório significativos, comparáveis aos fármacos padrão.

The whole plant of the methanolic extract from Leucas cephalotes was screened for invitro antioxidant (using the DPPH method), invivo analgesic (using hot plate test in mice) and anti-inflammatory (using rat paw edema test) activities. The methanolic extract of Leucas cephalotes (MELC) scavenged the DPPH radicals in a dose-dependent manner. The IC50 value to scavenge DPPH radicals was found to be 421.3µg/ml. A significant (p<0.0005) analgesic activity was observed at 60 min with 200 mg/kg, and 400 mg/kg exhibited maximum activity. The maximum anti-inflammatory response was produced at 3 hr and 2 hr with doses of 200 and 400 mg/kg, respectively. These results suggest that the methanolic extract from Leucas cephalotes exerts significant analgesic and anti-inflammatory effects, which were comparable with standard drugs.

A new tetradentate Schiff base, 3-[(Z)-2-piperazin-l-yl-ethylimino]-l, 3-dihydro indol-2-one was synthesized by the condensation of isatin(Indole-2,3-dione) with l-(2-aminoethyl)piperazine(AEP). Its complexes with Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Hg(II), U0(2)(VI) and Th(IV) have been synthesized and characterized by microanalysis, conductivity, UV-visible, FT-IR, 'H NMR, TGA and magnetic susceptibility measurements. The complexes have 1:1 metal to ligand stoichiometry. The complexes of Cu(II) and Th(IV) are 1:1 electrolytes whereas the complexes of Co(II), Ni(II), Zn(II), Cd(II), Hg(II) and U0(2)(VI) are nonelectrolytes. ITie spectral data revealed that the ligand acts as a neutral tetradentate, coordinating through the azomethine nitrogen, two piperazine nitrogen atoms and carbonyl oxygen. Octahedral geometry for Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II) complexes and a coordination number of 8 for U0(2)(VI) and Th(IV) complexes are proposed. The ligand and its metal complexes were screened for antibacterial activity against Bacillus subtilis, Staphylococcus aureus (S. aureus), Escherichia Coli (E. Coli) and Pseudomonas aeruginosa and the complexes are more potent bactericides than the ligand. The anthelmentic activity of the ligand and its complexes against earthworms was also tested.

The gluteal region is an important anatomical and clinical area which contains muscles and vital neurovascular bundles. They are important for their clinical and morphological reasons. In this manuscript we report a rare case of absence of inferior gluteal artery. In the same specimen the superior gluteal artery was taking origin from the anterior division of internal iliac artery. The structures normally supplied by the inferior gluteal artery were supplied by a branch coming from the superior gluteal artery. The developmental and clinical significance of the anatomical variation is discussed

La región glútea es una importante área anatómica y clínica, la cual contiene músculos y vitales elementos neurovasculares. Estos últimos son importantes por razones clínicas y morfológicas. En este trabajo describimos un raro caso de ausencia de la arteria glútea inferior. Encontramos también que la arteria glútea superior tenía su origen en la división anterior de la arteria iliaca interna. Las estructuras irrigadas normalmente por la arteria glútea inferior estaban irrigadas por una rama que se originaba de la arteria glútea superior. Son discutidos el desarrollo y el significado clínico de esta variación anatómica
