Published: January 2020

Abstract
In this work we investigate the formation of elongated gold nanoparticles (NPs), which occurred by laser ablation of gold target in aqueous solutions containing CaCl2. In all our experiments Ytterbium fiber laser (wavelength at 1060-1070 nm, pulse width of 200 ns, pulse repetition rate of 20 kHz, pulse energy of 1 mJ) was used as a radiation source. In the present work first, laser-assisted formation of elongated Au nanoparticles by ablation of a solid Au (99, 99%) target in liquid was done using this laser source. Extinction spectra correlating with TEM images of the mentioned above nanoparticles show the appearance of absorption signal in red region and near IR-spectrum that corresponds to longitudinal plasmon resonance of electrons in elongated nanoparticles. Second, generated elongated Au nanoparticles were exposed to pulsed laser beam with different pulse energy and ablation time. The peculiarity of the experiments is the use of additives of bivalent cations. The experiments on irradiation of the gold target by laser ablation in liquid were carried out in water obtained by Milli-Q purification system with different concentration of calcium chloride (CaCl2). Extinction spectra show pronounced shift to red region in the absorption maximum with increasing concentration. Results of other experiments show that formation of elongated gold nanoparticles as chains is common process under laser ablation of the solid target in the presence of some divalent ions in water. The paper discusses the mechanisms of formation of elongated nanoparticles by laser ablation of solids depending on the concentration of divalent ions in the liquid and the time of laser exposure.

Abstract
The introduction of nanotechnology in nuclear imaging has gained significant interest and could have promising potential for clinical use. Tumor imaging with radiolabeled nanoparticles (NPs) may be used for early detection, characterization, staging of disease, and for monitoring treatment efficacy. In this study we evaluated the biodistribution of porous silicon NPs labeled with positron-emitter gallium-68 in Wistar rats with subcutaneously transplanted cholangioma RS-1. The uptake of 68Ga-NPs in tumor tissue was 0.24±0.02 %ID/g at 5 min postinjection (p.i.) and climbed to 0.87±0.07 %ID/g at 5 h p.i. On the other hand, the amount of free 68Ga injected as 68GaCl3 solution decreased from 0.34±0.07 %ID/g at 5 min p.i. to 0.07±0.01 %ID/g at 5 h p.i. The highest level of radioactivity revealed in liver (8.27–15.79 %ID/g), spleen (0.98–1.27 %ID/g), and lungs (0.98–1.80 %ID/g). 68Ga-NPs were also determined in blood: up to 3.33±0.14 %ID/g at 5 min p.i. The uptake of 68Ga-NPs in other organs and tissues didn’t exceed 1 %ID/g. In conclusion, the obtained results suggest that 68Ga-NPs could be suitable for use as molecular imaging probes.

Abstract
Surgical removal of glial tumors is a challenge due to their infiltrative growth. At the moment, the main way to solve this problem is fluorescent intraoperative navigation. However, in the absence of accumulation of a fluorescent marker in tumor tissues, other diagnostic parameters are required to find the boundaries of such tumors. Raman spectroscopy has the advantages of optical spectroscopy such as speed and non-invasiveness. With an exhaustive database of reference spectra of those components that can be expressed in glial tumors, Raman spectroscopy allows for diagnostics of such tumors and their intraoperative demarcation. The purpose of this work was to study healthy brain tissues and intracranial tumors of laboratory animals and humans in order to detect significant differences using spectroscopy of spontaneous Raman scattering. Also, the analysis of cultures of tumor and immunocompetent cells was carried out. The results of the study showed significant differences in the spectral lines related to lipids, proteins and nucleic acids, which can be used to develop an optical biopsy method of brain tumors based on Raman spectroscopy.

Wildland fire reburning trends across the US West suggest only short-term negative feedback and differing climatic effects
Authors: Buma B , Weiss S , Hayes K , Lucash M 
Published: January 2020

Abstract
Wildfires are a significant agent of disturbance in forests and highly sensitive to climate change. Short-interval fires and high severity (mortality-causing) fires in particular, may catalyze rapid and substantial ecosystem shifts by eliminating woody species and triggering conversions from forest to shrub or grassland ecosystems. Modeling and fine-scale observations suggest negative feedbacks between fire and fuels should limit reburn prevalence as overall fire frequency rises. However, while we have good information on reburning patterns for individual fires or small regions, the validity of scaling these conclusions to broad regions like the US West remains unknown. Both the prevalence of reburning and the strength of feedbacks on likelihood of reburning over differing timescales have not been documented at the regional scale. Here we show that while there is a strong negative feedback for very short reburning intervals throughout wildland forests of the Western US, that feedback weakens after 10–20 years. The relationship between reburning intervals and drought diverges depending on location, with coastal systems reburning quicker (e.g. shorter interval between fires) in wetter conditions and interior forests in drier. This supports the idea that vegetation productivity—primarily fine fuels that accumulate rapidly (<10 years)—is of primary importance in determining reburn intervals. Our results demonstrate that while over short time intervals increasing fires inhibits reburning at broad scales, that breaks down after a decade. This provides important insights about patterns at very broad scales and agrees with finer scale work, suggesting that lessons from those scales apply across the entire western US.

Published: January 2020

Abstract
This research aimed to find out the peatland river fishermen’s adapting strategy against the climate change and the effects of strengthening the strategy. This study was an action research using participatory rural appraisal. The results showed that so far the fishermen employed local wisdom in predicting the fish output of the peatland river. The method considered the rainy days rate in mapping the quantity of tuakang, pelumpung, toman, and snakehead freshwater fish species. Local flood occurrences became the main indicator of the initiation for high fish production period. The water hyacinths preservation in pandanus forest to support fish reproduction and sunlight-dependence manual fish processing indicated the naturefriendly behaviour of fishermen community. Several attempts have been taken to reinforce the adaptation strategy of fishermen, i.e.: (1) developing the capacity of fishermen group, including preparing the fish season calendar and, fishermen time map, also fishermen institution relation map; (2) conducting training for fish processing verification; and (3) advising on the processing of water hyacinth for alternative products.

Published: January 2020

Abstract
The sustainable management of palm oil can be achieved through a regulatory approach. Indonesia as one of the largest palm oils producing countries in the world is committed to achieving sustainable palm oil management in order to reduce greenhouse gas emissions as an effort to combat climate change impact. The concretization of this commitment is to require the Presidential Instruction Number 8 of 2018 concerning Palm Moratorium. However, the Presidential Instruction Number 8 of 2018 has limitations in its authority to be implemented. Therefore, it requires synchronization with relevant regulations to provide a strong legal position for the implementation of the Presidential Instruction Number 8 of 2018. Therefore, the purpose of this study is to analyze the synchronization between the Presidential Instruction Number 8 of 2018 and other relevant regulations. To achieve this goal, the author employed a normative approach in the form of an analysis of the contents of the regulation that needs to be synchronized. The results of this study indicated that there are fundamental problems at the level of regulation regarding the sustainable palm oil management that are contradictory to each other, making it difficult for Indonesia to fulfill its commitment to reduce the emission of greenhouse gases to combat climate change as part of its effort to combat climate change.

Published: January 2020

Abstract
When the haze disaster struck several regions in Indonesia (especially Kalimantan and Sumatra) in 2015, various parties tried to get involved in saving the environment and preventing the effects of climate change. Republika Daily, as a leading media brand in Indonesia, showed its social responsibility through news photo of the smog that adorned its front page. By interviewing the editor-in-chief of Republika in-depth and searching for documents online, we identified the reasons why Republika concerned on the haze disaster as part of the impacts of climate change, why using smoggy photojournalism, and how Republika’s social responsibility regarding the environmental disaster arose. Pathetic facts in the field related to the natural conditions, victims of local communities who had suffered the health problems, and economic losses caused by the haze disaster prompted Republika to not only call-for-public-awareness but also call-for-public-action in overcoming the problems and helping the victims. Therefore Republika used smoggy photojournalism to make the public ‘feel’ the conditions on the ground. This research can inspire other media to participate in saving the environment and increasing climate change awareness through creative and impactful ways.

Published: January 2020

Abstract
Corporate Social Responsibility (CSR) in business activities is now a fairly popular trend. This is done as a form of compensation for business activities that affect the activities of the community and the surrounding environment. It is well known that CSR contributes quite significantly to environmental preservation and inhibits climate change. CSR activities use the community development concept, hence local community involvement would determine the performance of the design and implementation of CSR programs. This study aims to analyze the local factors that play a role in providing an impact on the performance of CSR activities. In this paper, two methods were used sequentially, namely in-depth interviews to openly explore prospective factors, and the Delphi method for agreeing the intended factors. CSR officers and Community Development consultants were the object of research. The results show that the strength of values/cultural factors, the strength of actors, the attention of actors in regional development, the strength of actor networks, the participation of community components and local government are factors considered as factors that have an impact on CSR performance.

Abstract
Drought is a major problem in rice production in rainfed areas. Climate change has exacerbated the negative effect of drought on the sustainability of rice production. Development of drought tolerant rice varieties is important strategy to minimize rice yield losses in drought prone areas. This study aimed to determine drought tolerance of twenty-five advanced rice breeding lines under artificial drought environment and to evaluate their agronomic performance in rainfed lowland rice areas. Evaluation of drought tolerance was carried out at seedling stage in greenhouse. Yield trial was conducted in rainfed rice area in Indramayu district, West Java province, during wet season 2017-2018. The trial was designed in randomized complete block design with four replications. Result from this study indicated a variation in drought tolerance of twenty-five breeding lines. Two lines showed highly tolerant response to drought in seedling stage namely B15231-MR-10-1 and B15143C-TGB-12. The grain yield of highly drought tolerant rice line B15231-MR-10-1 (4.81 t ha-1) was comparable to popular rice varieties Situ Bagendit (4.56 t ha-1) and Ciherang (5.09 t ha-1). Drought tolerant rice breeding lines identified from this study have potential to be adopted by farmers in drought prone rainfed areas as an adaptation strategy to the impact of climate change.
