Refrigeration needs for sustainable preservation of horticultural products

Fresh horticultural products are highly perishable and need refrigeration for further preservation. Refrigeration needs energy consumption with consequent economical cost and damage for the environment. The objective of the present work was to use efficiently the refrigeration according to the product needs and time for consumption. Salicornia ramosissima and Sarcocornia perennis fresh branch tips, which are used for fresh salads, were stored at 1, 4 and 9 °C for up to 21 days. In both species, fresh tips were of good consumer acceptability for up to 14 days at 9°C. At 1 and 4 °C fresh tips could be stored in good conditions up to 21 days. For efficient use of energy in refrigeration of fresh salicornia and sarcocornia we conclude that if it is to put those products in the market earlier we can use the higher temperature for storage saving energy. Only for further storage we shall use the lower temperatures.

Linking law: practical guidelines for delivering law to rural Victoria using e-learning technologies

These guidelines provide information, analysis and practical tips for organisations seeking to use digital technologies to enhance general and professional legal education for people living in remote, rural and regional (RRR) Victoria. Given the difficulties people living in RRR areas still face in having to take time away from work and home and travel long distances to attend many legal educational events, it makes sense to explore these options. However, it can be particularly difficult for organisations seeking to engage with RRR people to choose between educational technologies and techniques, given the considerable hype and movement in the field at present. Options are plentiful and complex, with multiple practical and organisational considerations attached to each, and the situation changes frequently as technologies improve. The increasing reach of high-speed internet and mobile networks is creating opportunities for different and more engaging educational methods to be used in most regional and rural areas, but fast internet is not the be-all and end-all. There is much that can be achieved with intelligent use of a range of lower-tech options including low-speed internet, phone, DVD and regional site-based educational technologies.

Professional partnerships in children's services: working together for children

Early childhood education and care services in Australia are moving towards an integrated approach to service delivery requiring educators to work in partnership with professionals from sectors such as health, education and community services for the benefit of young children and their families. This means that educators need to work in perhaps new and different ways in their everyday work.Professional partnerships in children’s services: Working together for children looks at ways educators can work effectively with other professionals in building and leading these partnerships in children’s services. It examines some of the issues surrounding working in partnership with others and the implications this has for understanding and enacting leadership. It explores topics such as:•working collaboratively in early childhood education and care settings•thinking about the knowledge base of others•transdisciplinarity—a new strategy to consider•examples of collaborative practice with otherprofessionals in early childhood education and care services are provided.Examples are given that have been implemented in early childhood education and care services to work collaboratively with other professionals. Professional partnerships in children’s services: Working together for children points to a way forward by encouraging the rethinking and reworking of practice by educators with the inclusion of reflective questions, scenarios from services and top tips for educators to consider.

End of life care - the importance of advance care planning

Background: Communication about end of life care may involve difficult conversations for patients, family members and health professionals. However, a lack of understanding of a person's wishes about their future care may result in a loss of dignity for the person, and additional distress for their family members and health professionals and burden to the healthcare system. Objective: This article discusses the barriers to advance care planning and provides some guidance for the general practitioner in undertaking advance care planning with patients and their families. Tips for initiating end of life discussions with patients and families utilising the 'PREPARED' acronym, and ensuring appropriate care delivery are included. Discussion: Involving patients and their family members in advance care planning may be challenging and time consuming for GPs. However, there are a number of resources to support this activity in relation to training, communication support and Medicare item funding.

Theoretical study on the (1-012) deformation twinning and cracking in coarse-grained magnesium alloys

This paper theoretically and systematically investigates: (1) the effect of local transformed strains within deformation twinning on twin intersection; (2) the fracture mode based on type I co-zone tensile twin intersection in coarse-grained magnesium alloys, as well as the impacts of twin intersection and grain diameter on interfacial crack nucleation along twin boundaries; and (3) the influence of the local stresses arising from the encountered twin bands on crack growth. A novel dislocation-based strain nucleus model and a Green's function method, which are applicable to any material with local transformations in which elastic properties are reasonably approximated as isotropic, are specifically employed to model the concentrated transformed strain and calculate the local stress field resulting from deformation twinning and the stress intensity factors at crack tips in the magnesium alloys, respectively. In addition, an electron backscatter diffraction (EBSD) measurement is provided for crack nucleation originating from Type I co-zone tensile twin intersection. The theoretical modeling indicates: (i) the local strains within barrier twins strongly dictate the growth of incident twins and enhance the twin propagation stress; (ii) larger grains favor brittle fracture. More specifically, the dislocation reactions and pile-ups at the junctions between tensile twins can result in interfacial crack nucleation and growth along the twin boundaries, which is a brittle fracture mode based on lower twinning stress and stress concentration in the coarse-grained magnesium alloys; and (iii) the direction of crack propagation is easily changed by high-density twin bands and twin intersections owing to the local strains.

Antimicrobial activity of Eucalyptus tereticornis and comparison with daily life antibiotics

Eucalyptus is a fast growing tree which has shown to possess high degree of resistance against stressed environmental conditions. Eucalyptus tereticornis is widely cultivated in various parts of the world even in Pakistan. The medicinal properties of this tree reside in its oil. The main aim of our study is to check the antimicrobial activity of this valuable tree and to compare it with commercially available antibiotics. Eucalyptus tereticornis oil was extracted from the fresh leaves and branch tips during flowering season from surrounding areas of Hazara University, Pakistan. Different concentrations of oil were checked against Gram positive bacteria Staphylococcus aureus (ATCC 6538), Enterococcus faecalis (ATCC 49452), Gram negative bacteria including Escherichia coli (ATCC 25922), Salmonella typhimurium (ATCC 14028) and Pseudomonas aeruginosa (ATCC 27853), and also against yeast Candiada albican (ATCC 2091). The oil was significantly active against all the microbes studied. The activity of E. tereticornis oil was compared with standard antibiotics Ciprofloxacin (CIP-5 μg), Chloramphenicol (C-30 μg), Tetracycline (TE-30 μg) and Ampicillin (AMP 25-μg). The comparison gives the significant results and proves the antimicrobial efficiency of this valuable plant.

Étude du rôle de la membrane basale spécialisée dans la maturation de l'émail

Les cellules épithéliales qui produisent l’émail, les améloblastes, sont séparées de l'émail au niveau de la zone de maturation par une membrane basale spécialisée (MBS) enrichie en laminine 332 (LM-332). Cette protéine hétérotrimérique (composée des chaînes α3, ß3 et γ2) assure l'intégrité structurelle des membranes basales (MB) et influence divers processus cellulaires épithéliaux tels que l'adhésion et la différenciation cellulaire. Des modèles de souris « knockout » (KO), où les gènes codant pour LM-332 ont été supprimés, meurent peu après la naissance. Néanmoins, ce phénotype létal peut être contourné en substituant chez la souris le gène produisant la chaîne γ2 de la laminine (LAMC2) par sa forme humaine, sous le contrôle de l’expression du promoteur-rtTA, de la cytokératine 14, inductible par la prise de doxycycline (Dox) - (Tet-on). Le but de ce projet est d’examiner si l’utilisation de cette protéine humaine chez la souris a un effet sur la structuration de la MBS ainsi que sur la maturation de l'émail. La phase de maturation de l’organe de l’émail chez la souris transgénique a été sévèrement altérée par rapport à une souris normale (WT). La MBS n’est plus visible, une matrice dystrophique s’est formée dans la couche d'émail dans la phase de maturation, et la présence d’une matrice résiduelle de l'émail est observée durant la phase tardive de maturation. Des micro-analyses tomographiques ont révélé une usure excessive des surfaces occlusales des molaires, un écroulement de l'émail sur les pointes des incisives et une hypominéralisation de l'émail. Cependant, aucune altération structurale due à cette recombinaison transgénique n’a été observée dans d'autres sites épithéliaux, tels que la peau, le palais et la langue. Ces résultats indiquent que, bien que ce modèle de souris humanisée soit capable de rétablir ses fonctions dans divers tissus épithéliaux, il est incapable de soutenir la structuration d'une MBS à l'interface entre les améloblastes et l’émail en maturation. Cet échec peut être lié à la composition spécifique de la MBS dans la phase de maturation et supporte l’hypothèse que la MBS est essentielle pour la maturation adéquate de l'émail.

THE ROLE OF ECTOMYCORRHIZAL FUNGI ON FERTILIZED AND UNFERTILIZED NURSERY GROWN WHITE SPRUCE

Nursery grown seedlings are an essential part of the forestry industry. These seedlings are grown under high nutrient conditions caused by fertilization. Though grown in a controlled environment, symbionts such as ectomycorrhizal fungi (EcMF) are often found in these conditions. To examine the effects of EcMF in these conditions, colonized Picea glauca seedlings were collected from Toumey Nursery in Watersmeet, MI. After collection, the EcMF present were morphotyped, and seedlings with different morphotypes were divided equally into two treatment types- fertilized and unfertilized. Seedlings received treatment for one growing season. After that time, seedlings were collected, ectomycorrhizas identified using morphotyping and DNA sequencing, and seedlings were analyzed for differences in leaf nutrient concentration, content, root to shoot ratio, total biomass, and EcMF community structure. DNA sequencing identified 5 unique species groups- Amphinema sp. 1, Amphinema sp. 5, Thelephora terrestris, Sphaerosporella brunnea, and Boletus variipes. In the unfertilized treatment it was found that Amphinema sp. 1 strongly negatively impacted foliar N concentration. In fertilized seedlings, Thelephora terrestris had a strong negative impact on foliar phosphorus concentration, while Amphinema sp. 1 positively impacted foliar boron, magnesium, manganese, and phosphorus concentration. In terms of content, Amphinema sp. 1 led to significantly higher content of manganese and boron in fertilized treatments, as well as elevated phosphorus in unfertilized seedlings. Amphinema sp. 5 had a significant negative effect on phosphorus content. When examining root to shoot ratio and biomass, those seedlings with more non-mycorrhizal tips had a higher root to shoot ratio. Findings from the study shed light on the interactions of the species. Amphinema sp. 5 shows very different functionality than Amphinema sp. 1. Amphinema sp. 1 appears to have the highest positive effect on seedling nutrition when in both fertilized and unfertilized environments. Amphinema sp. 5 and T. terrestris appear to behave parasitically in both fertilized and unfertilized conditions.

Photonic packaging: transforming silicon photonic integrated circuits into photonic devices

Dedicated multi-project wafer (MPW) runs for photonic integrated circuits (PICs) from Si foundries mean that researchers and small-to-medium enterprises (SMEs) can now afford to design and fabricate Si photonic chips. While these bare Si-PICs are adequate for testing new device and circuit designs on a probe-station, they cannot be developed into prototype devices, or tested outside of the laboratory, without first packaging them into a durable module. Photonic packaging of PICs is significantly more challenging, and currently orders of magnitude more expensive, than electronic packaging, because it calls for robust micron-level alignment of optical components, precise real-time temperature control, and often a high degree of vertical and horizontal electrical integration. Photonic packaging is perhaps the most significant bottleneck in the development of commercially relevant integrated photonic devices. This article describes how the key optical, electrical, and thermal requirements of Si-PIC packaging can be met, and what further progress is needed before industrial scale-up can be achieved.

Effect of sonic and ultrasonic activation on organic tissue dissolution from simulated grooves in root canals using sodium hypochlorite and EDTA

Aim: To compare soft-tissue dissolution by sodium hypochlorite, with an EDTA intermediate rinse, with or without activation with passive ultrasonic activation (PUI) or sonic activation using the Endoactivator (EA) or Eddy tips (ED). Methodology: The root canals of eighty-three human maxillary central incisors were chemo-mechanically prepared and the teeth split. A standardized longitudinal intracanal groove was created in one of the root halves. Eighty-three porcine palatal mucosa samples were collected, adapted to fit into the grooves and weighed. The re-assembled specimens were randomly divided into four experimental groups (n = 20), based on the final rinse: no activation; EA; PUI; ED, using 2.5% sodium hypochlorite, with an EDTA intermediate rinse. A control group (n = 3) was irrigated with distilled water without activation. The solutions were delivered using a syringe and needle 2 mm from working length. Total irrigation time was 150 s, including 60 s of activation in the specific groups. The study was carried out at 36 ± 2 °C. The porcine palatal mucosa samples were weighed after completion of the assays. Student paired t-test and anova were used to assess the intra- and intergroup weight changes. The multiple comparisons were evaluated using Bonferroni correction (α = 0.05). Results: Weight loss occurred in all experimental groups. Irrigant activation resulted in greater weight loss when compared to the nonactivated group [vs. EA (P = 0.001); vs. PUI (P < 0.001); vs. ED (P < 0.001)]. No significant differences were found amongst the different activation systems. Conclusions: Activation increased the tissue-dissolving activity of irrigants from artificial grooves in root canals of maxillary central incisors. © 2016 International Endodontic Journal.
