Abstract In this article, we investigate the Kenmotsu manifold when applied to a Dα-homothetic deformation. Then, given a submanifold in a Dα-homothetically deformed Kenmotsu manifold, we derive the generalized Wintgen inequality. Additionally, we find this inequality for submanifolds such as slant, invariant, and anti-invariant in the same ambient space.

Resumen En este artículo estudiamos la variedad de Kenmotsu cuando se aplica a una deformación Dα-homotética. Luego, dada una subvariedad en una variedad de Kenmotsu Dα-homotéticamente deformada, derivamos la desigualdad de Wintgen generalizada. Adicionalmente, encontramos esta desigualdad para subvariedades tales como oblicuas, invariantes y anti-invariantes en el mismo espacio ambiente.

Resumo O presente estudo foi enfocado na incidência de carrapatos e doenças transmitidas por carrapatos (TTBD) em bovinos mestiços (Friesian x Sahiwal) de duas fazendas (n = 2.548) no distrito de Lahore, Paquistão. Foram coletados 572 carrapatos (adultos e ninfas) e amostras de sangue (10 ml) para microscopia, ou seja, esfregaço sanguíneo - coloração de Giemsa (BST) e análise molecular; Reverse Line Blot-General Primer-PCR (RLB-PCR) e Specific Primer PCR (SP-PCR) -, de bovinos infestados (n = 100) nos meses de abril a setembro. Resultados: A espécie de carrapato identificada em ambas as fazendas foi Rhipicephalus microplus, com diferença significativa na taxa de infestação nos dois locais (p < 0,0001). Os bovinos mestiços Friesian, com maior proporção de sangue, e Sahiwal, com menor proporção de sangue, foram principalmente infestados por carrapatos (p < 0,0458) e hemoparasitos (p < 0,474), e vice-versa. O SP-PCR mostrou maior número de infecção por hemoparasitos do que a BST, revelando 16% de Theileria annulata (p < 0,0001; k valor 0,485; 0,0001), 51% de Babesia bigemina (p < 0,0001; k valor 0,485; 0,0001) e 15% de Anaplasma marginale (p < 0,001; valor de k 0,207; 0,001). A infecção única com B. bigemina foi de 34% (n = 34/100), e com A. marginale, de 6% (n = 6/100). A dupla infecção com T. annulata/B. bigemina foi de 8% (n = 8/100), e com B. bigemina/A. marginale, de 1% (n = 1/100). Já a tripla infecção com T. annulata/B. bigemina/A. marginale foi de 8% (n = 8/100). O estudo filogenético da sequência isolada de T. annulata revelou estreita homologia com isolados do Irã (87%), de B. bigemina com isolados de Cuba (94 a 100%) e de A. marginale com isolados do Paquistão (98 a 99%).

Abstract The present study was focused on the incidence of ticks and tick-borne diseases (TTBD) in cross-bred cattle (Friesian x Sahiwal) of two farms (n = 2548) in district Lahore, Pakistan. We collected total of 572 ticks (adults and nymphs) and blood samples (10 ml) for microscopic i.e., blood smear test - Giemsa Stain (BST) and molecular analysis; Reverse Line Blot-General Primer-PCR (RLB-PCR) and Specie Specific Primer PCR (SP-PCR) from infested cattle (n = 100) from months of April to September. Results: The tick specie identified was Rhipicephalus microplus at both farms, with significant difference in infestations rate amongst both farms (p< 0.0001). The cross-bred cattle having higher ratio of Friesian blood and lower ratio of Sahiwal blood were mostly infested by ticks (p < 0.0458) and haemoparasites (p <0.474) and vice versa. The SP-PCR showed higher number of haemoparasites infection than BST, which revealed 16% T. annulata (p < 0.0001 and k value 0.485, 0.0001), 51% B. bigemina (p < 0.0001 and k value 0.485, 0.0001) and 15% A. marginale (p < 0.001 and k value 0.207, 0.001), respectively. The single infection with B. bigemina was 34% (n = 34/100) and A. marginale 6% (n = 6/100). The double infection with T. annulata/B. bigemina was 8% (n = 8/100) and B. bigemina/A. marginale 1% (n = 1/100). Whereas the triple infection with T. annulata/B. bigemina/A .marginale was 8% (n = 8/100). The phylogenetic study of isolated sequence of T. annulata revealed close homology to isolates from Iran (87%), B. bigemina to isolates from Cuba (94 to 100%) and A. marginale with isolates from Pakistan (99 to 98%).

In this study the radiation-induced degradation of crystal violet (CV) dye under various experimental conditions has been investigated. D0.5, D0.9 and D0.99 values suggests that lower doses are required for 50%, 90% and 99% removal of CV dye when the sample solution contains excessive amount of �OH radicals. The removal efficiency of CV dye in terms of G-values was also calculated under each reaction conditions. The results showed that �OH radicals are playing effective role in the degradation of CV dye as compared to e aq‒ and .H radicals. The gamma irradiation process effectively degraded CV dye at all pH values. The organic byproducts were examined and accordingly degradation pathway was proposed.

This study reports the degradation of ciprofloxacin (CIP) by means of ionizing radiations. Kinetic studies with aqueous concentrations of 4.6, 10, 15, 17.9 mg/L reveals that degradation of CIP follows pseudo-first order kinetics and the decay constant increased with decrease in initial concentration of CIP. The removal efficiency, represented by G-value, decreased with increasing absorbed dose and increased with higher [CIP]0 concentration at a given absorbed dose. The effects of bubbling CIP solution with N2, N2O or air on CIP degradation were also studied. The influence of various radical scavengers like tert-butanol, iso-propanol, HCO3- , CO3(2-) , NO3- and NO2- as radical scavengers in N2- saturated solutions of CIP indicated that 'OH were more closely associated with the radiolytic decomposition of CIP than other radicals, such as e-aq or ·H. The pH value of aqueous media played a crucial role in the degradation of CIP. It was observed that degradation efficiency was higher under acidic condition compared to degradation in natural or alkaline media. F-, CH3COO- and HCOO- were formed as a result of CIP degradation that were analyzed by ion-chromatography.

Fetal heart rate (FHR) monitoring is a routine for obtaining significant information about the fetal condition during pregnancy and labour. Fetal condition may change abruptly during the pregnancy period. Therefore, a continuous fetal electrocardiogram (FECG) monitoring will ease the fetal well-being. An algorithm has been developed to detect R-peak for the simultaneous measurement of the fetal and maternal hearts rates during pregnancy and labor for fetal monitoring. The algorithm is based on a cross-correlation, adaptive threshold and statistical properties in the time domain. The performance achieved for the R-peak detection for the heart rate measurements shows that the model can extract R-peak for both, mother and fetus utilizing a single-lead configuration. The algorithm has been implemented in the field of propagation gate array (FPGA). The design was synthesized and fitted into Altera’s Stratix EP1S10 using the Quartus II platform because of its enhanced DSP capability. Test case results showed an error percentage of around ± 0.3% and ± 0.5% for the R-peak detection of maternal and fetal mortality respectively. The system is capable of running at a maximum clock frequency of 48.56MHz, and consumes 9633 logic elements, 101616 memory space and 4 units of DSP blocks.

El monitoreo de la frecuencia cardiaca fetal (FHR) es una rutina para obtener información significativa sobre el estado del feto durante el embarazo y el parto. La condición fetal puede cambiar abruptamente durante el período de embarazo. Por lo tanto, un continuo monitoreo fetal por medio de electrocardiograma (FECG) facilitará el bienestar fetal. Se ha desarrollado un algoritmo para detectar el pico R para la medición simultánea de las frecuencias cardiacas fetal y materna durante el embarazo y el trabajo de monitorización fetal. El algoritmo se basa en la correlación cruzada del umbral adaptativo y propiedades estadísticas en el dominio del tiempo. El desempeño obtenido para la detección del pico R para las mediciones del ritmo cardíaco muestra que el modelo puede extraer picos R para ambos madre y feto utilizando una configuración de una sola via. El algoritmo ha sido implementado en el arreglo de compuertas de propagación (FPGA). El diseño fué sintetizado y acomodado en Stratix de Altera EP1S10 utilizando la plataforma Quartus II debido a su capacidad DSP mejorada. Los resultados de las pruebas de caso mostraron un porcentaje de error de alrededor de ± 0,3% y ± 0,5% para la detección R-pico de la mortalidad materna y fetal, respectivamente. El sistema es capaz de funcionar a una frecuencia de reloj máxima de 48.56MHz, y consumes 9633 elementos lógicos, 101616 espacio de memoria y 4 unidades de bloques DSP.
