Providing adhesion for a miniture mobile intra-abdominal device based on biomimetic principles

This paper investigates the surface adhesion characteristics required for a miniature mobile device to move around the abdominal cavity. Such a device must be capable of adhering to the tissue lining and move freely across the upper surface of the insufflated abdomen. Accordingly, the potential of utilising bioinspired solutions to facilitate wet adhesion is assessed

Drivability analysis of through-the-road-parallel hybrid vehicles

In the last decade, Hybrid Electric Vehicles (HEVs) have spread worldwide due to their capability to reduce fuel consumption. Several studies focused on the optimisation of the energy management system of hybrid vehicles are available in literature, whilst there are few articles dealing with the drivability and the dynamics of these new powertrain systems. In this paper a ‘Through-the-Road-Parallel HEV' is analysed. This architecture is composed of an internal combustion engine mounted on the front axle and an electric motor powering the rear one. These two powertrains are not directly connected to each other, as the parallel configuration is implemented through the road-tyre force interaction. The main purpose of this paper is the drivability analysis of this layout of HEVs, using linearised mathematical models in both time (i.e. vehicle response during tip-in tests) and frequency domain (i.e. frequency response functions), considering the effect of the engaged gear ratio. The differences from a traditional Front-Wheel-Drive (FWD) configuration are subsequently highlighted. Furthermore, the authors compare different linearised dynamic models, with an increasing number of degrees of freedom, in order to assess which model represents the best compromise between complexity and quality of the results. Finally, a sensitivity analysis of the influence of the torque distribution between the front (thermal) and rear (electric) axles on vehicle drivability is carried out and presented in detai

Effectiveness of Triploidization on Ingir-ingir (Mystus Nigriceps) with Different Fertilization and Heat Shock

This research was conducted in August until November 2015 in the Fish Hatchery and Breeding Laboratory, Faculty of Fisheries and Marine Sciences, University of Riau, Pekanbaru. This research was aimed to know the triploidization effectiveness in fertilized egg of ingir-ingir larvae (Mystus nemurus) with different fertilization and heat shock. The method used in this research was the experimental method; 2 factors, 10 treatments and 3 replications. Fresh eggs and milt were fertilization, then 1, 2 and 3 minutes after fertilization zygotes were shocked by heat shock 400C for 1, 2 and 3 minutes. The treatments were, P0K0 (as control), P1K1, P1K2, P1K3, P2K1, P2K2, P2K3, P3K1, P3K2, P3K3. The result shown that the best results in treatment Fertilization Rate (P3K1=31,06%), Hatching Rate (P2K1=65,74%), Survival Rate of 4 days and Survival Rate of 21 days (P3K3=71,82% and 41,67%), the length and width of a red blood cell were (0.192 mm and 0.123 mm)

Effects of Feeding Feed Enriched Curcumin Turmeric (Curcuma Domestica Val) Overview of the Red Blood Cellspangasius Hypophthalmus

This research was conducted in June-August 2016. The purpose of this study was todetermine the effect of feeding feed enriched curcumin turmeric (Curcuma domestica Val)to the picture of the red blood cells (total erythrocytes, hematocrit, and hemoglobinconcentration) Pangasiushypophthalmus and infected by Aeromonas hydrophilla. Thedesign used was Completely Randomized Design (CRD) with one factor, the level 5treatments and 3 replications. The treatments were feeding enriched curcuminextract withdifferent dose i.e Kn = negative control (feeding without being given curcumin extract andwere not infected byAeromonashydrophilla); Kp = positive control (feeding without beinggiven curcumin extract and infected byAeromonashydrophilla); P1 = addition of curcuminextract in feed at a dose of 0.3 g/kg; P2 = addition of curcumin extract in feed at a dose of0.5 g/kg; and P3 = addition of curcumin extract in feed at a dose of 0.7 g/kg. The resultsshowed that feeding enriched curcuminextract against of Pangasiushypophthalmus at adose of 0.7 g/kg (P3) is the best dose for Pangasiushypophthalmuswith a total oferythrocyte 1.87x106 cells/mm3, hematocrit 35.33 %, and hemoglobin concentration of 7.66g/dl after infected byAeromonashydrophilla and generate growth in absolute weight of 3.66g and a survival rate of 100 %

Identification of Pathogenic Bacteria of Tilapia (Oreochromis Niloticus) in Subdistrict Marpoyan Damai Pekanbaru

This research was done in April - Juni 2014 in Fish Disease Parasite and Laboratories and an Experiment of the Faculty of Fisheries and Marine Science University of Riau. This study aims to determine the types of pathogens that attack tilapia in District Marpoyan Damai Pekanbaru. The benefits of this research is to provide information to farmers about the types of pathogens in tilapia, so it can be the prevention of disease. The method used in this study is a survey method by taking samples in the field and analyzed in the laboratory. The amount of bacteria found from both the ponds was six species. Bacteria found in a pond one these were Aeromonas hydrophila, Basillus sp, Pseudomonas sp and Streptococcus sp. Meanwhile bacteria found in a pond two these were Basillus sp, Stapyhilococcus sp, and Edwardsiella tarda

Diagnostic Utility of the Impact of Event Scale-Revised in Two Samples of Survivors of War

The study aimed at examining the diagnostic utility of the Impact of Event Scale-Revised (IES-R) as a screening tool for post-traumatic stress disorder (PTSD) in survivors of war. The IES-R was completed by two independent samples that had survived the war in the Balkans: a sample of randomly selected people who had stayed in the area of former conflict (n = 3,313) and a sample of refugees to Western European countries (n = 854). PTSD was diagnosed using the MINI International Neuropsychiatric Interview. Prevalence of PTSD was 20.1% in the Balkan sample and 33.1% in the refugee sample. Results revealed that when considering a minimum value of specificity of 0.80, the optimally sensitive cut-off score for screening for PTSD in the Balkan sample was 34. In both the Balkan sample and the refugee sample, this cut-off score provided good values on sensitivity (0.86 and 0.89, respectively) and overall efficiency (0.81 and 0.79, respectively). Further, the kappa coefficients for sensitivity for the cut-off of 34 were 0.80 in both samples. Findings of this study support the clinical utility of the IES-R as a screening tool for PTSD in large-scale research studies and intervention studies if structured diagnostic interviews are regarded as too labor-intensive and too costly

Optical control of spin textures in quasi-one-dimensional polariton condensates

We investigate, through polarization-resolved spectroscopy, the spin transport by propagating polariton condensates in a quasi one-dimensional microcavity ridge along macroscopic distances. Under circularly polarized, continuous-wave, non-resonant excitation, a sinusoidal precession of the spin in real space is observed, whose phase depends on the emission energy. The experiments are compared with simulations of the spinor-polariton condensate dynamics based on a generalized Gross-Pitaevskii equation, modified to account for incoherent pumping, decay and energy relaxation within the condensate.Comment: 10 pages, 9 figure

Corrosive-Abrasive Wear Induced by Soot in Boundary Lubrication Regime

Soot is known to induce high wear in engine components. The mechanism by which soot induces wear is not well understood. Although several mechanisms have been suggested, there is still no consensus. This study aims to investigate the most likely mechanism responsible for soot-induced wear in the boundary lubrication regime. Results from this study have shown that previously suggested mechanisms such as abrasion and additive adsorption do not fully explain the high wear observed when soot is present. Based on the results obtained from tests conducted at varying temperature and soot levels, it has been proven that the corrosive–abrasive mechanism was responsible for high wear that occurred in boundary lubrication conditions
