The importance and significance of heritage conservation of ex-tin mining landscape in Perak, the Abode of Grace

The thematic history of tin mining in Perak reveals the evolution of tin production, technology, infrastructure, transportation, social and the state economic development. The mining expansion that spread from Larut district to Kinta at the end of nineteenth century has distinctively impact on it's landscape. The surviving evidences that spread over Kinta demonstrates the importance and significance of conservation of ex-tin mining places. These surviving evidences are testimony of the past history and legacy for the present and future generations.

A review of the conservation ecology of round-leaf Pomaderris Pomaderris vacciniifolia F. Muell. ex Reissek (Rhamnaceae)

Round-leaf Pomaderris Pomaderris vacciniifolia F. Muell. ex Reissek (Rhamnaceae) is a Victorian endemic shrub listed as threatened under the Flora and Fauna Guarantee Act 1988 and critically endangeredunder the Environment Protection and Biodiversity Conservation Act 1999. A review of the available literature for P. vacciniifolia indicated most information is anecdotal or found in unpublished works. Better understanding of the ecology of P. vacciniifolia may help explain why it is vulnerable, and enhance future management. Future research should focus towards better understanding of P. vacciniifolia habitat, reproductive ecology, seed dispersal mechanisms and competitive ability and how these compare with more common sympatric congeners, to determine whether any differences could explain the relative success of these species. Targeted searches for this species on public and private land are warranted to reveal additional populations and fully appreciate the distribution of this species.

Community attitudes toward the reintegration of ex-prisoners

 This study explored community readiness to support ex-prisoner reintegration; a sentencing objective requiring active community participation. Findings indicate the community support reintegration. Certain conditions maximised support. Abstract reintegrative policy was endorsed over personal involvement in ex-prisoner reintegration; ex-prisoners demonstrating an ability to be ‘redeemed’ and non-stereotypical ex-offender-types received greater support.

Ex situ electrochemical sodiation/desodiation observation of Co₃O₄ anchored carbon nanotubes: a high performance sodium-ion battery anode produced by pulsed plasma in a liquid

Liquid plasma, produced by nanosecond pulses, provides an efficient and simple way to fabricate a nanocomposite architecture of Co3O4/CNTs from carbon nanotubes (CNTs) and clusters of Co3O4 nanoparticles in deionized water. The crucial feature of the composite's structure is that Co3O4 nanoparticle clusters are uniformly dispersed and anchored to CNT networks in which Co3O4 guarantees high electrochemical reactivity towards sodium, and CNTs provide conductivity and stabilize the anode structure. We demonstrated that the Co3O4/CNT nanocomposite is capable of delivering a stable and high capacity of 403 mA h g(-1) at 50 mA g(-1) after 100 cycles where the sodium uptake/extract is confirmed in the way of reversible conversion reaction by adopting ex situ techniques. The rate capability of the composite is significantly improved and its reversible capacity is measured to be 212 mA h g(-1) at 1.6 A g(-1) and 190 mA h g(-1) at 3.2 A g(-1), respectively. Due to the simple synthesis technique with high electrochemical performance, Co3O4/CNT nanocomposites have great potential as anode materials for sodium-ion batteries.

Evaluation of nanoformulated therapeutics in an ex-vivo bovine corneal irritation model

Aim : To determine the internalization and protective effects of potential ophthalmic formulations and nanoformulated natural proteins in ex-vivo bovine corneal alkali burn model.

Methods : The bovine cornea obtained were subjected to the 0.5 N NaOH insult that induced alkali burn and inflammation as observed in the in vivo situation. The toxic effects of the nanoformulation were evaluated in the normal and insult induced cornea using histological analysis. Internalization studies were carried out using in vivo imaging and analysis (IVIS, PerkinElmer, USA).

Results : The nanoformulations employed in this study showed no obvious changes in the integrity of the cornea. Further, improvements in the light transmittance and reduced inflammation were observed. The IVIS showed a dose dependant increase in the uptake of the nanoformulations with time.

Conclusion : The nanoformulated bovine lactoferrin and SurR9-C84A (SR9) proteins evaluated in the ex vivo bovine corneal irritation model is the first of its kind, and we report here the non-toxic and therapeutic potential of these formulations for topical applications.
