This experiment arranged a completely randomized design (CRD) with 4 probiotic levels of local microbes (0%, 1%, 2%, and 3%) and 5 replications. The data obtained were analyzed using Analysis of Variance at 1% and continued with Polynom Orthogonal test at 1%. The result of this research showed that the additional of probiotic from local microbial (0%, 1%, 2%, and 3%) was not significant effect (P>0,05) to the number of erythrocytes of layer, but highly significant effect (P <0,01) to the number of hemoglobin. Probiotic levels of local microbial (0%, 1%, 2%, and 3%) can increase the number of hemoglobin with regression equality (Ŷ = 6,68 + 0,48X).

This study was conducted to 1) determine the effect local of probiotic supplements on shell thickness, weight loss persentage, and Haugh unit of eggs which stored ten days; 2) determine the optimal level of supplements local of probiotic on shell thickness, weight loss presentage, and Haugh unit of eggs which stored ten days. This research was held on 08--19 December 2014 in the CV. Varia Agung Jaya henhouse laying in the District of Seputih Mataram, Center of Lampung Regency and continued on 20 December 2014--18 January 2015 in the Laboratory of Microbiology, Laboratory of Molecular Biology Faculty, University of Lampung. The study used completely randomized design (CRD) with 4 treatments of local probiotics in the diet (0%, 1%, 2%, and 3%) and 5 replications. Data obtained was analyzed using analysis of variance at 5% level and continued Orthogonal Polynomial test at 5% level. Based on these results we can conclude: effect of local probiotics in the diet (0,1,2, and 3%) no significant (P> 0.05) on the weight loss presentage and Haugh unit of eggs which stored ten days, but significant (P <0.05) on shell thickness. Increasing the percentage of local probiotic on the ration will improve shell thickness indicated by the regression equation ŷ = 0.42 + 0,24x, with r = 0.68 and R2 = 0.47.

SPORT: A new sub-nanosecond time-resolved instrument to study swift heavy ion-beam induced luminescence - Application to luminescence degradation of a fast plastic scintillator

We developed a new sub-nanosecond time-resolved instrument to study the dynamics of UV-visible luminescence under high stopping power heavy ion irradiation. We applied our instrument, called SPORT, on a fast plastic scintillator (BC-400) irradiated with 27-MeV Ar ions having high mean electronic stopping power of 2.6 MeV/\mu m. As a consequence of increasing permanent radiation damages with increasing ion fluence, our investigations reveal a degradation of scintillation intensity together with, thanks to the time-resolved measurement, a decrease in the decay constant of the scintillator. This combination indicates that luminescence degradation processes by both dynamic and static quenching, the latter mechanism being predominant. Under such high density excitation, the scintillation deterioration of BC-400 is significantly enhanced compared to that observed in previous investigations, mainly performed using light ions. The observed non-linear behaviour implies that the dose at which luminescence starts deteriorating is not independent on particles' stopping power, thus illustrating that the radiation hardness of plastic scintillators can be strongly weakened under high excitation density in heavy ion environments.Comment: 5 figures, accepted in Nucl.

Ion beam generated surface ripples: new insight in the underlying mechanism

A new hydrodynamic mechanism is proposed for the ion beam induced surface patterning on solid surfaces. Unlike the standard mechanisms based on the ion beam impact generated erosion and mass redistribution at the free surface (proposed by Bradley-Harper (BH) and its extended theories), the new mechanism proposes that the ion beam induced saltation and creep processes, coupled with incompressible solid flow in amorphous layer, leads to the formation of ripple patterns at the amorphous/crystalline (a/c) interface and hence at the free surface. Ion beam stimulated solid flow inside the amorphous layer controls the wavelength, where as the amount of material transported and re-deposited at a/c interface control the amplitude of ripples. The new approach is verified by designed experiments and supported by the discrete simulation method.Comment: 12 pages, 6 figures. arXiv admin note: substantial text overlap with arXiv:1206.082

Evaluation of two lyophilized molecular assays to rapidly detect foot-and-mouth disease virus directly from clinical samples in field settings

Accurate, timely diagnosis is essential for the control, monitoring and eradication of foot‐and‐mouth disease (FMD). Clinical samples from suspect cases are normally tested at reference laboratories. However, transport of samples to these centralized facilities can be a lengthy process that can impose delays on critical decision making. These concerns have motivated work to evaluate simple‐to‐use technologies, including molecular‐based diagnostic platforms, that can be deployed closer to suspect cases of FMD. In this context, FMD virus (FMDV)‐specific reverse transcription loop‐mediated isothermal amplification (RT‐LAMP) and real‐time RT‐PCR (rRT‐PCR) assays, compatible with simple sample preparation methods and in situ visualization, have been developed which share equivalent analytical sensitivity with laboratory‐based rRT‐PCR. However, the lack of robust ‘ready‐to‐use kits’ that utilize stabilized reagents limits the deployment of these tests into field settings. To address this gap, this study describes the performance of lyophilized rRT‐PCR and RT‐LAMP assays to detect FMDV. Both of these assays are compatible with the use of fluorescence to monitor amplification in real‐time, and for the RT‐LAMP assays end point detection could also be achieved using molecular lateral flow devices. Lyophilization of reagents did not adversely affect the performance of the assays. Importantly, when these assays were deployed into challenging laboratory and field settings within East Africa they proved to be reliable in their ability to detect FMDV in a range of clinical samples from acutely infected as well as convalescent cattle. These data support the use of highly sensitive molecular assays into field settings for simple and rapid detection of FMDV
