Opis:
Governments, corporations, and other organizations are expanding further into remote locations, such as polar regions, space, and other relatively inaccessible areas with minimal development. However, with this increased interest in remote areas, there is a shortage of scholarly work to draw upon for operating in these regions. Therefore, this presents an opportunity to fill an academic gap, and the article asks, ‘How can sustainability be a source of competitive advantage for logistics in remote locations?’ To explore this question and to serve as a resource for future researchers, the article defines key terms, utilizes an interdisciplinary framework by integrating the academic disciplines of business and sustainability, and supplies a detailed literature review. From this groundwork, the article follows a qualitative methodology whereby three hypotheses emerge. The research results offer that sustainability can be a source of competitive advantage for logistics in remote locations by: sustainable logistics innovation; reducing, reusing, and recycling; and optimizing supply networks. Finally, the article closes with a discussion and summary, by recognizing research limitations and by contributing recommendations for future dialogue and research.

Opis:
Superconducting layers in silicon and germanium are fabricated via gallium implantation through a thin $SiO_2$ cover layer and subsequent rapid thermal annealing. Gallium accumulation at the $SiO_2//Si$ and $SiO_2//Ge$ interfaces is observed but no pure gallium phases were found. In both cases superconducting transition occurs around 6-7 K which can be attributed to the metallic conducting, gallium rich interface layer. However, the superconducting as well as the normal-state transport properties in gallium overdoped silicon or germanium are different.

Opis:
Copper indium gallium diselenide (CIGS) becomes more significant for solar cell applications as an alternative to silicon. The quality of the layer has a critical impact on the final efficiency of the solar cell. An influence of the post-deposition millisecond range flash lamp annealing on the optical and microstructural properties of the CIGS films was investigated. Based on the Raman and photoluminescence spectroscopy, it is shown that flash lamp annealing reduces the defect concentration and leads to an increase of the photoluminescence intensity by a factor of six compared to the nonannealed sample. Moreover, after flash lamp annealing the degradation of the photoluminescence is significantly suppressed and the absolute absorption in the wavelength range of 200-1200 nm increases by 25%.

Opis:
The aim of this study was to investigate the impact of feed supplements with alfa-amylase and beta-glucanase (Optipartum C+ 200) on ingestive-related behaviour biomarkers registered with real-time sensors: rumination behaviours and reticulorumen parameters (pH and temperature). Cows (n=20) in the treatment group (TG) were fed with Optipartum C+ 200 (Enzymes feed supplement: Alfa-Amylase 57 Units; Beta-Glucanase 107 Units) from 21 days before calving until 30 days after calving with a feeding rate of 200 g/cow/day. Cows (n=22) in the control group (CG) were fed a feed ration without feed supplement. Measurements started from 6 days before calving and continued until 21 days after calving. The following indicators were registered: with the RumiWatch System: Rumination time; Eating time; Drinking time; Rumination chews; Eating chews; Drinking gulps; Bolus; Chews per minute; Chews per bolus. With the SmaXtec system: the temperature, pH of the contents of the cows’ reticulorumens, and cows’ walking activity. According to our results, feed supplementation with alfa-amylase and beta-glucanase (Optipartum C+ 200) in the TG group resulted in increases in the following parameters: 9% rumination time and eating time, 19% drinking time, 11% rumination chews, 16% eating chews, 13% number of boluses per rumination, 5% chews per minute and 16% chews per bolus. The rumination time showed a strong, positive relation with rumination chews and bolus indicators in both groups (TG and CG) (p<0.001); while the rumination time in both groups of cows showed an opposite direction and was negatively related to eating time and eating chews (p<0.05). We found a 1.28 % lower reticulorumen pH and a 0.64 % lower reticulorumen temperature in cows fed with the supplement compared with cows in the control group. Cows in TG were 8.80% more active than those in the CG group. For improvement of ingestive-related behaviour we suggest adding a feed supplement with alfa-amylase and beta-glucanase (Optipartum C+ 200).
