In mathematical investigations, these fluids are modeled in terms of traditional integer-order partial differential equations (PDEs). It is recognized that traditional PDEs cannot decode the complex behavior of physical flow parameters and memory effects. Therefore, this article intends to study the mixed convection heat transfer in nanofluid over an inclined vertical plate via fractional derivatives approach. The problem in hand is modeled in connection with Atangana–Baleanu fractional derivatives without singular and local kernel with a strong memory. Human blood is considered as base fluid and carbon nanotube (CNTs) (single-wall carbon nanotubes (SWCNTs) and multi-wall carbon nanotubes (MWCNTs)) are dispersed into it to form blood-CNTs nanofluid. The nanofluid is considered to flow in a saturated porous medium under the influence of an applied magnetic field. The exact analytical expression...

Most of the existing approaches use regression on density maps for the crowd count from a single image. However, these methods cannot localize individual pedestrian and therefore cannot estimate the actual distribution of pedestrians in the environment. On the other hand, detection-based methods detect and localize pedestrians in the scene, but the performance of these methods degrades when applied in high-density situations. To overcome the limitations of pedestrian detectors, we proposed a motion-guided filter (MGF) that exploits spatial and temporal information between consecutive frames of the video to recover missed detections. Our framework is based on the deep convolution neural network (DCNN) for crowd counting in the low-to-medium density videos. We employ various state-of-the-art network architectures, namely, Visual Geometry Group (VGG16), Zeiler and Fergus (ZF), and VGGM in the framework of a region-based DCNN for detecting pedestrians. After pedestrian detection, the proposed motion guided filter is employed. We evaluate the performance of our approach on three publicly available datasets. The experimental results demonstrate the effectiveness of our approach, which significantly improves the performance of the state-of-the-art detectors.

We also present the convergence analysis of these iterative methods. To assess the validity and performance of these iterative methods, we have applied to solve some nonlinear problems.

Metronidazole and cephalosporins are considered as best choice for prophylactic use in gastrointestinal operations. Therefore, the study is established to reveal the comparative effect of metronidazole, ceftriaxoine sodium and their combination on the tensile strength of jejunual anastomotic site. A total of twenty healthy stray dogs were included in this study. These dogs were randomly divided into four groups, which underwent end to end jejunal ansastmosis. The dogs in Group I (control) were operated for jejunal anstomosis without any antibiotic prophylaxis. The metronidazole alone was administered intravenously to dogs in Group II at the dose rate of 50mg/kg while the dogs in Group III were administered with intravenous ceftriaxone sodium at the dose rate of 30mg/Kg body weight two hours prior to surgery. The dogs in Group IV were given metronidazole in combination with ceftriaxone sodium by intravenous route at the dose rate of 50mg/Kg and 30mg/kg respectively two hours before surgical intervention. A significant difference was noted in the tensile strength between the four studied groups (P < 0.05). The study concluded that the combination of ceftriaxone sodium with metronidazole was found to enhance the gain in tensile strength significantly i.e. 47.50 %.

CMI against dinitrochlorobenzene (DNCB) and sheep red blood cells (SRBC) in rabbits was determined by delayed-type hypersensitivity and macrophage engulfment assay (MEA), respectively; whereas, HI to Pasteurella multocida B2 vaccine and SRBC was determined by indirect haemagglutination assay (IHA) and Jerne hemolytic plaque formation assay (JHPFA), respectively. The rabbits were divided into four major groups (A through D) each subdivided into four subgroups (1 through 4). Rabbits of group A served as vehicle control while those of groups B, C and D were treated with ivermectin at the dose rates of 200 μg/kg, 400 μg/kg and 600 μg/kg b.w., respectively. Cellular immunity was determined in subgroups 1 and 2 through DNCB and MEA, respectively while HI was determined in subgroups 3 and 4 through IHA and JHPFA, respectively. The skin sensitivity to DNCB at 24 and 48 h and macrophage engulfment of SRBC were highest (P N 0.05) in rabbits administered with 600 μg/kg b.w. The highest geometric mean titers (14.00 ± 0.31) and number of plaque forming units (1860 ± 0.75) were found in rabbits that received ivermectin at a dose of 600 μg/kg b.w. followed, in order by the groups that received 400 μg/kg, 200 μg/kg b.w. and controls. Leukocyte counts were significantly higher in ivermectin-treated groups (C and D) than group A (vehicle control) and B (ivermectin at the rate of 200 μg/kg). A graded dose immune response suggested an immunopotentiating effect of ivermectin at higher doses.

Data were collected prospectively on a predesigned form and collated. Diagnoses of different diseases/disorders were based on clinical examination supplemented with relevant laboratory tests. A total of 463 entries of 34 different clinical diseases/disorders were recorded. Sarcoptic mange (35% of 200 camels) followed by anhidrosis (23%) and trypanosomosis (19%) were the three most frequently encountered disorders. The body system most often involved was the integument (31%) followed by gastrointestinal (21%), locomotory (12%), thermoregulatory (6%), blood (6%), urogenital (6%), lymphatic (3%), nervous (3%), respiratory (3%) and ocular (3%).
