Karakterisasi Aroma dan Rasa Beberapa Varietas Beras Lokal melalui Quantitative Descriptive Analysis Method

Improvement of the national rice production could be done by using superior variety (VUB), which has early age ofmaturity and high productivity. However, the farmers, until now, still fanatics to grow the local rice. The utilization oflocal varieties as genetic resources for producing new superior varieties is expected to be solution. The study used sevenlocal rice varieties (Anak Daro, Si Buyung, Cicih Merah, Mentik Wangi, Bengawan Solo, Rojolele, and Mandoti), to testthe aroma and taste. Quantitative Descriptive Analysis (QDA) using trained panelists was applied. Data obtained wereanalyzed by Multivariate Analysis of Principle Component Analysis technique. Results showed that Mandoti and Rojolelehave similar aroma and characterized by pandan, cereals, buttery, and green aroma. Cicih Merah characterized by creamyand sweet aroma. Mentik Wangi, Bengawan solo, and Anak Daro have similar properties but are not characterized by adistinctive aroma. Flavors of Cicih Merah and Bengawan solo are in one group and characterized by a taste of sweet andumami. Mandoti are in different groups and characterized by a taste of salty and bitter. Mentik Wangi and Si Buyung,Anak Daro and Rojolele even be in one group but not characterized by a distinctive flavor attributes

Setting the e-Commerce Scene: A Qualitative Investigation of the Use of Nature Imagery in User Interface Design

User experience designers often employ natural landscapes as background imagery in e-commerce user interfaces (UI). However, at this stage, there is only limited work on how nature imagery in UI design affects user perception and behaviour. In this paper, we present a qualitative study involving semi-structured interviews into the use of nature imagery in UI design. Our study builds on theories in environmental psychology and seeks to develop a theoretical framework for the role of nature imagery in user perception and behaviour. Further, building on the expertise of user experience practitioners and end users, we seek to develop theoretically-grounded design guidelines for the capture, selection, and integration of nature imagery in e-commerce UI designs

Antimicrobial and anti-inflammatory activity of chitosan-alginate nanoparticles: a targeted therapy for cutaneous pathogens.

Advances in nanotechnology have demonstrated potential application of nanoparticles (NPs) for effective and targeted drug delivery. Here we investigated the antimicrobial and immunological properties and the feasibility of using NPs to deliver antimicrobial agents to treat a cutaneous pathogen. NPs synthesized with chitosan and alginate demonstrated a direct antimicrobial activity in vitro against Propionibacterium acnes, the bacterium linked to the pathogenesis of acne. By electron microscopy (EM) imaging, chitosan-alginate NPs were found to induce the disruption of the P. acnes cell membrane, providing a mechanism for the bactericidal effect. The chitosan-alginate NPs also exhibited anti-inflammatory properties as they inhibited P. acnes-induced inflammatory cytokine production in human monocytes and keratinocytes. Furthermore, benzoyl peroxide (BP), a commonly used antiacne drug, was effectively encapsulated in the chitosan-alginate NPs and demonstrated superior antimicrobial activity against P. acnes compared with BP alone while demonstrating less toxicity to eukaryotic cells. Together, these data suggest the potential utility of topical delivery of chitosan-alginate NP-encapsulated drug therapy for the treatment of dermatologic conditions with infectious and inflammatory components

Stagnation point reverse flow combustor for a combustion system

A combustor assembly includes a combustor vessel having a wall, a proximate end defining an opening and a closed distal end opposite said proximate end. A manifold is carried by the proximate end. The manifold defines a combustion products exit. The combustion products exit being axially aligned with a portion of the closed distal end. A plurality of combustible reactant ports is carried by the manifold for directing combustible reactants into the combustion vessel from the region of the proximate end towards the closed distal end

Using art to assess environmental education outcomes

Construction of developmentally appropriate tools for assessing the environmental attitudes and awareness of young learners has proven to be challenging. Art-based assessments that encourage creativity and accommodate different modes of expression may be a particularly useful complement to conventional tools (e.g. surveys), but their efficacy and feasibility across diverse contexts has not been adequately explored. To examine the potential utility of integrating art into evaluations of environmental education outcomes, we adapted an existing drawing prompt and corresponding grading rubric to assess the environmental attitudes and awareness of children (ages 6–12) at summer camps in Athens, GA, USA (n = 285). We then compared children’s drawings with scores on a more typical survey instrument that measured similar outcomes, the Children Environmental Perception’s Scale. Results showed that a drawing prompt was a practical and unique learner-centered tool for measuring distinct components of environmental attitudes and awareness. Findings also revealed different response patterns across the two instruments, highlighting the value of using multiple approaches (e.g. art-based and survey-based) to assess cognitive and affective aspects of children’s environmental orientations

Evaluasi Mutu Beras Untuk Menentukan Pola Preferensi Konsumen Di Pulau Jawa

Java is the most populated area as well as the highest consumers of rice in Indonesia. Until now, rice widely grown in Java is still dominated by Ciherang. This research aimed to study the patterns of rice consumer preferences in Java to be used as one of main considerations for dissemination and new varieties breeding program. Evaluation was done by conducting sensory and physicochemical analysis on five most purchased rice brand of each province on Java. Hedonic and ranking test was assessed by 1000 panelists from all the five provinces in Java. Physicochemical analysis was carried out in the Proximate Laboratory in Indonesian Center for Rice Research (ICRR), Sukamandi. The results showed that, in general, consumer preferences in each province have a similar pattern except in DIY. Consumers in West, East, and Central Java as well as in DKI Jakarta prefer rice with intermediate amylase content, while those in DIY prefer low amylase rice. Gelatinization temperature of rice is mostly high gelatinization temperature except those in DIY that were dominated by low gelatinization temperature rice. Moreover, rice color influences consumer preferences in Java except on consumers in West Java who chose rice not based on the level of rice color. Correlation analysis between consumer preferences in general with all other variables showed that consumer preferences in general were significantly affected only by the amylose content and was not influenced by other parameters. Whiteness degree of rice significantly related to consumer preferences based on color and very significant correlation based on rice translucency and taste

An Accurate Determination of the Exchange Constant in Sr_2CuO_3 from Recent Theoretical Results

Data from susceptibility measurements on Sr_2CuO_3 are compared with recent theoretical predictions for the magnetic susceptibility of the antiferromagnetic spin-1/2 Heisenberg chain. The experimental data fully confirms the theoretical predictions and in turn we establish that Sr_2CuO_3 behaves almost perfectly like a one-dimensional antiferromagnet with an exchange coupling of J = 1700^{+150}_{-100}K.Comment: revised and reformatted paper with new title to appear in Phys.
