In this study, we investigated the drying properties of Sentang (Azadirachta excelsa) dried at different temperatures. Sentang tree planted in Kelantan, Malaysia, was used in this study. Drying specimens with dimensions of 30 ×150 × 500 mm were dried under air-drying conditions, a constant temperature of 60, 80, 100, and 120 °C until the moisture content (MC) of the specimens reaches an equilibrium moisture content (EMC) at each drying condition. The drying properties of the specimens were then examined. The results confirmed that drying temperature had a significant effect on drying time. As expected, drying Sentang under air-drying conditions demanding considerable time than the other drying conditions. © Published under licence by IOP Publishing Ltd.

Utilization of critical land as woody biomass plantations need to be supported by information on the potential of critical land. The objective of this research was to delineate a critical land using remote sensing and GIS techniques combined with Analytical Hierarchy Process method. The parameters used were land use/cover, slope, rainfall erosivity, tolerable soil erosion, soil erodibility, land management, and land productivity. The Analytical Hierarchy Process method was used to provide the weight of each parameter. Land use/cover map was interpreted from SPOT-7 satellite imageries acquired in 2017. The other parameter maps were built based on reference maps, secondary and field data collection as well as soil sample analysis. The resulted map showed that 32.7% area of East Lombok Regency was categorized as a critical area. Based on the land status, the critical land area located in the State forest was smaller (42%) than on the Area for Other Utilization (58%). Utilization of critical land as woody biomass plantation should be prioritized on the shrub-covered land using community forest scheme, while for the area of State forest, the plantation can be only planted in the production forest area applying industrial plantation forest or community plantation forest scheme. © 2019 Published under licence by IOP Publishing Ltd.

As a non-thermal technique for food processing with a “clean label”, high pressure is commonly used for starch modification. In this study, the impact of high pressure on Pueraria montana var. thomsonii starch (PMS) of different varieties (Fenge7 (FG7), Fenge12 (FG12) and Fenge75 (FG75)) were investigated under two pressure levels (100 and 400 MPa) with different high pressure duration (10 and 20 min). The results showed that the particle size of starch increased significantly from 9.84 μm to 10.9 μm, the relative crystallinity decreased from 24.4 % to 19 % (at 400 MPa/20 min in FG75), and apparent amylose content increased by up to 13.7 % in FG7. While preserving the native C-type crystalline pattern, high pressure treatment significantly influenced functional properties. Compared to the native starch, solubility of FG75 reduced from 7.59 % to 5.24 % (400 MPa/20 min). In addition, pasting properties improved markedly, with FG75 exhibiting peak viscosity up to 2077 cP, while hardness decreased by 45.75 % in FG12 under 400 MPa/20 min. In general, these findings emphasize that high-pressure treatment effectively regulates the function of PMS, improves viscosity and reduces degradation, and provides valuable information for the application of high pressure technology in modifying PMS.

Conformal ceramic electrodes utilized in prior recordings of nonhuman primate prefrontal cortical layer 2/3 and layer 5 neurons were used in this study to record tonic glutamate concentration and transient release in layer 2/3 PFC. Tonic glutamate concentration increased in the Match (decision) phase of a visual delayed-match-to-sample (DMS) task, while increased transient glutamate release occurred in the Sample (encoding) phase of the task. Further, spatial vs. object-oriented DMS trials evoked differential changes in glutamate concentration. Thus the same conformal recording electrodes were capable of electrophysiological and electrochemical recording, and revealed similar evidence of neural processing in layers 2/3 and layer 5 during cognitive processing in a behavioral task.

Tropical forests and woodlands are key components of the global carbon and water cycles. Yet, how climate change affects these biogeochemical cycles is poorly understood because of scarce long-term observations of tropical tree growth. The recent rise in tropical tree-ring studies may help to fill this gap, but a large-scale quantitative analysis of their potential in global change research is missing. We compiled a list of all tropical tree species known to form annual tree rings and built a network encompassing 492 tropical ring-width chronologies to evaluate the potential to generate insights on climate sensitivity of woody productivity and to build centuries-long reconstructions of climate variability. We assess chronology quality, length, and climatic representativeness and explore how these change along climatic gradients. Finally, we applied species-distribution modeling to identify regions with potential for tree-ring studies in ecological and climatic studies. The number of tropical chronologies has rapidly increased, with ∼400 added over the past two decades. Yet, tree-ring studies are biased towards high-elevation locations, with gaps in warmer and wetter climates, on the African continent, and for angiosperm species. The longest chronologies with strongest climate signals (i.e., synchronous growth variations among trees) are from cool regions. In wet regions, climate signals and precipitation sensitivity decrease. Most tropical regions harbor 5–15 (and up to 80) species with proven potential to generate chronologies. The potential for long climate reconstructions is particularly high in drier high elevation sites. Our findings support strategies to effectively expand tree-ring research in the tropics, by targeting specific species and regions. Tropical dendrochronology can importantly contribute to global change research by generating historical context of climate extremes, quantifying climate sensitivity of woody productivity and benchmarking vegetation

To meet the local and international market’s timber demands, Azadirachta excelsa, a native tree locally known as a Sentang, has been listed among the potential fast-growing species to be planted for forest plantation establishment in the mid -1990s by the Malaysian government. Understanding wood properties is well known as crucial for the industry to use it as a raw material properly. Because of the underrepresented and limited accessible data on the tree’s qualities, the species’ potential has been determined. The physical properties of the 25-year-old Sentang tree planted in Gurun, Kedah, Malaysia, were discussed in this paper. The impact of radial growth rates on moisture content, density, and shrinkage from the pith to the bark at the stump, DBH, middle, and top of the trees is investigated in this paper. As a result, three trees were cut and classed as slow, average, or fast-growing. The results were as follows. From the pith to the bark, the green MC of all classed trees continues to diminish. The density, on the other hand, did not follow the same pattern; however, fast-growing trees have lower densities than slower-growing trees at the bottom, DBH, middle, and top of the trees. Tangential, radial, and longitudinal shrinkage appeared to reduce as tree height climbed, then increase again at the trees’ tops.

Azadirachta excelsa, known as Sentang by a native, a fast-growing and light-hardwood tree, was one of the selected species included in forest plantation projects in the mid-1990s by the Malaysian government to supply timber demands for local and international markets. Ambiguity has been pointed out about the species potential due to understudied and limited data available regarding the properties of the tree. This paper investigates the physical properties of 26 years old Sentang tree planted at Jeli, Kelantan, Malaysia. This paper focuses on the effects of radial growth rates on moisture content, density, and shrinkage from the pith to the bark at the stump, diameter-breast height (DBH), middle, and top of the trees. Three trees were categorized into slow, average, and fast growth rates were selected and harvested for this purpose. The green moisture content (MC) of all the categorized trees tends to decrease from the pith to the bark. However, the same tendency was not observed in the density. As predicted, the shrinkage in the tangential direction is higher than in radial and longitudinal directions.

Detecting Bacterial Leaf Blight (BLB) in paddy fields is one of the essential issues in Indonesia to prevent losses in rice production. This study reports the effectiveness of textural analysis using drone-acquired data over paddy fields in West Java, evaluating the potential of integrating textural and thermal characteristics. We used drone data combined with machine learning techniques to distinguish different levels of BLB impact. The normalized difference texture index derived from Haralick textural features was used as a predictor. The findings revealed that incorporating textural features enhanced the disease detection accuracy significantly compared with the traditional approach based on spectral indices. The random forest algorithm, which merges texture and vegetation indices, achieved a classification accuracy of 0.984. The proposed method offers a robust, noninvasive solution for BLB disease detection, contributing substantially to safeguarding crop yields and mitigating global food security issues. © 2024, The Authors.
