Peningkatan Mutu Kompos Kiambang MelaluiAplikasi Teknologi Hayati Dan Kotoran Ternak Sapi

Kiambang (Salvinia natans) which a water plant became a seriously problem in the use of Reservoir Batutegi, because nearly 80% of its surface covered by Salvinia natans. The presence of highly abundant of Salvinia natans have highly potential to be used as a source of organic fertilizer. The purpose of this study was to examine the effect of the application of biological technology (decomposers) and cow manure on the quality of the resulting compost kiambang. This study used randomized block design and experiment arranged in factorial 4 x 4 with three replications. The first factor was the dose of decomposers which consists of 4 levels, namely A1 = 0 ml, A2 = 20 ml, 30 ml dose = A3, and A4 = 40 ml decomposers per quintal kiambang respectively. The second factor was the dose of cattle dung, i.e. B1 = 0 kg, B2 = 10 kg, 20kg = B3, and B4 = 30 kg manure per quintal kiambang. The results showed the compost that has the best quality in terms of physical and chemical compost was the compost derived from the treatment of 30 ml and 40 ml decomposers per quintal kiambang which combined with 10 kg, 20 kg or 30 kg manure per quintal kiambang

A fracture condition incorporating the most unfavourable orientation of the crack

A fracture condition incorporating the most unfavourable orientation of the crack has been derived to improve the safety of loaded brittle components with complex shape, whose loading results in a three-dimensional stress state. With a single calculation, an answer is provided to the important question whether a randomly oriented crack at a particular location in the stressed component will cause fracture. Brittle fracture is a dangerous failure mode and requires a conservative design calculation. The presented experimental results show that the locus of stress intensity factors which result in mixed-mode fracture is associated with significant uncertainty. Consequently, a new approach to design of safety–critical components has been proposed, based on a conservative safe zone, located away from the scatter band defining fracture states. A postprocessor based on the proposed fracture condition and conservative safe zone can be easily developed, for testing loaded safety–critical components with complex shape. For each finite element, only a single computation is made, which guarantees a high computational speed. This makes the proposed approach particularly useful for incorporation in a design optimisation loop

Feed Markets in the Late Dry Season across Agro-Ecological Zones in Burkina Faso

Limited access to adequate quantities of high-quality feed is a major constraint to livestock productivity in smallholder systems in the West African Sahel. As a result of the increase in the livestock population and the associated growth in the demand for feeds, feed markets have sprung up in many cities and towns in the region. However, there is little available information on price variations for different feed types across agro-ecological zones in Burkina Faso. Information on feed price and quality is essential to developing strategies to match feed supply with demand. Surveys on the price and quality of feeds at nine feed markets in peri-urban areas across the four agro-ecological zones in Burkina Faso were conducted in the late dry season (March–May) in 2019. In each location, at least 10 feed sellers were interviewed. Samples of major feeds on sale at the markets were collected for laboratory analysis. Cowpea hay had the highest price of 394±53 FCFA per kg DM in Ouagadougou while the feed with the lowest price was sorghum straw, which was 30±2 FCFA per kg DM in Ouahigouya. For nearly all feeds, the prices were highest in Ouagadougou, which is presumably a reflection of higher demand. There was no correlation between price and quality (nitrogen concentration and in vitro organic matter digestibility (IVOMD) in the Ouagadougou market. However, there was a significant (P \u3c 0.05) positive relationship between price and nitrogen concentration in Dori, and between price and IVOMD in Bobo-Dioulasso and Ouahigouya markets. The results suggest that increasing demand for feed tends to drive up price particularly in the urban areas regardless of the quality. The findings in Dori, Bobo-Dioulasso and Ouahigouya indicate that there is opportunity to develop feed pricing based on quality

Emergence of Multidrug Resistance and Metallo‑beta‑lactamase Producing Acinetobacter baumannii Isolated from Patients in Shiraz, Iran

Background: Metallo‑beta‑lactamase (MβL) enzymes production is one of the most important resistance mechanisms against carbapenems in some bacteria including Acinetobacter baumannii. Aims: This study was aimed to determine the antimicrobial susceptibility and the prevalence of MβL among carbapenem‑resistant isolates of A. baumannii. Materials and Methods: In this cross‑sectional study from October 2012 to April 2013, 98 isolates were identified as A. baumannii using Microgen™ kits and confirmed by molecular method. These isolates were tested for antimicrobial susceptibilities by disk diffusion method according to the Clinical and Laboratory Standards Institute guidelines. Carbapenem‑resistant isolates were further detected phenotypically by MβL minimal inhibitory concentration (MIC)‑test strips, and subsequently positive MβL isolates were confirmed by polymerase chain reaction (PCR). Results: Overall, 98% (96/98) of A. baumannii isolates were detected as carbapenem‑resistant by MIC test. Highest sensitivity to the tested antibiotic with 42.9% (42/98) was observed to colistin. Of 96 carbapenem‑resistant isolates, 43 were phenotypically positive for MβL; out of 43 isolates, 37 were confirmed for the presence of MβL genes by PCR. Conclusion: The frequency of drug resistance among the clinical samples of A. baumannii isolated in our study against most of the antibiotics was very high. Moreover, all MβL producing isolates were multidrug resistance. Therefore, systematic surveillance to detect MβL producing bacteria and rational prescription and use of carbapenems could be helpful to prevent the spread of carbapenem resistance.Keywords: Acinetobacter baumannii, Antibiotic resistance, Carbapenem, Iran, Metallo‑beta‑lactamas

Towards Noncommutative Fuzzy QED

We study in one-loop perturbation theory noncommutative fuzzy quenched QED_4. We write down the effective action on fuzzy S**2 x S**2 and show the existence of a gauge-invariant UV-IR mixing in the model in the large N planar limit. We also give a derivation of the beta function and comment on the limit of large mass of the normal scalar fields. We also discuss topology change in this 4 fuzzy dimensions arising from the interaction of fields (matrices) with spacetime through its noncommutativity.Comment: 33 page

Challenging cisgenderism through trans people's narratives of domestic violence and abuse

By drawing on empirical research that explored trans people’s experiences of domestic violence and abuse (DVA), this paper problematises the ‘gender asymmetry debate' in DVA discourse. It does so by highlighting cisgenderism and a heteronormative bias which have led to the invisibility of a trans perspective. Qualitative data was collected via narrative interviews and this was examined using a voice-centred relational technique. A total of twenty four interviews were undertaken with trans people (n = 15) and domestic abuse practitioners (n = 9). In relation to the presentation and impact of DVA, and in the context of trans and cisgender people's abuse experiences, the research findings report both similarities and differences. Four narratives are presented here to illuminate both. This paper adds new insight and challenges normative and dominant discourses by promoting the need for further theorising about the gendered nature of domestic violence and abuse
