Abstract Assume $Gprec H$ are groups and ${cal A}subseteq {cal P}(G), {cal B}subseteq {cal P}(H)$ are algebras of sets closed under left group translation. Under some additional assumptions we find algebraic connections between the Ellis [semi]groups of the G -flow $S({cal A})$ and the H -flow $S({cal B})$ . We apply these results in the model theoretic context. Namely, assume G is a group definable in a model M and $Mprec ^* N$ . Using weak heirs and weak coheirs we point out some algebraic connections between the Ellis semigroups $S_{ext,G}(M)$ and $S_{ext,G}(N)$ . Assuming every minimal left ideal in $S_{ext,G}(N)$ is a group we prove that the Ellis groups of $S_{ext,G}(M)$ are isomorphic to closed subgroups of the Ellis groups of $S_{ext,G}(N)$ .

Abstract Given a Polish group G , let $E(G)$ be the right coset equivalence relation $G^{omega }/c(G)$ , where $c(G)$ is the group of all convergent sequences in G . The connected component of the identity of a Polish group G is denoted by $G_0$ . Let $G,H$ be locally compact abelian Polish groups. If $E(G)leq _B E(H)$ , then there is a continuous homomorphism $S:G_0rightarrow H_0$ such that $ker (S)$ is non-archimedean. The converse is also true when G is connected and compact. For $nin {mathbb {N}}^+$ , the partially ordered set $P(omega )/mbox {Fin}$ can be embedded into Borel equivalence relations between $E({mathbb {R}}^n)$ and $E({mathbb {T}}^n)$ .

This review deals with recent works on the process and technological aspects of wood-plastic composites (WPCs) manufacturing. WPCs relate to any composites that are built from wood and non-wood fibers and thermoplastic polymers. Recent progress relevant to wood-plastic composites has been reviewed in this article. T he process and technological aspects of WPC, such as raw materials, fabrication, mechanical, physical, thermal, and morphological properties, were outlined comprehensively. The manufacturing process of WPCs is an important aspect of WPCs production. Manufacturing methods like compression molding and pultrusion have some limitations. Extrusion and injection molding processes are the most widely used in WPC s due to their effectiveness. Recent developments dealing with WPCs and the use of different kinds of nanofillers in WPCs have also been presented and discussed . N anoclays are widely used as nanofiller s in WPCs because they represent an eco-friendly, readily available in large quantity, and inexpensive filler . WPCs can be found in a wide range of applications from construction to the automotive industry. Keywords: additive manufacturing, adhesion, fabrication techniques, mechanical and physical properties, wood-plastic composites

The main function of conservation institutions is to control breeding and wild plants and rescue wild plants and animals while maintaining the species purity. This role requires conservation institutions to contribute to animal conservation to save and conserve wild animals ex-situ . This research aims to determine the contribution value of Serulingmas Wildlife Recreation Park as an implementation of animal welfare . The data was collected through interviews and field observations. The results showed that the implementation achievement of animal welfare at Serulingmas Wildlife Recreation Park was classified as good with an achievement value of 76.61. However, t he contribution value of Serulingmas Wildlife Recreation Park to the animal conservation aspects was still categorized as low, w h i ch was mainly due to the low animal births . Increasing the success of animal births could be carried out through coaching on technical aspects such as improving animal health management and facilities.

A simple carbonization technique was applied to utilize Indonesian bamboo resources. Several ba mboo species as betung ( Dendrocalamus asper ), andong ( Gigantochloa pseudoarundinacea (Steudel) Widjaja), hitam ( G. atroviolacea ), tali ( G. apus ), kuning ( Bambusa vulgaris var. striata ), and ampel bamboo ( B. Vulgaris Scharad ) were selected for carbonization. Carbonization was conducted using a laboratory electrical furnace at 200, 400, 600, 800, and 1,000 1,000°C. The morphological and chemical properties of bamboos before and after carbonization were then analyzed. Betung, hitam, tali, kuning, and ampel bamboos had t ype IV structure which was the most common bamboo structure, while andong bambo had type III structure . Cracks in the fiber bundle were observed and became more visible with the increase of carbonization temperature. The pH showed a similar trend in all species. As a result of the electric conductivity test, carbonized andong and kuning bamboo showed higher value due to rich inorganic content. Kuning bamboo has a high value of potassium and silica content, which are suitable for use as fertilizer. The chemical structure transition of bamboo during the carbonization process was analyzed by FTIR spectroscopy, and significant changes were observed between 400 and 600°C. These results could be useful fundamental data for promoting high value-added bamboo utilization and improving research in Indonesian bamboo.

Morphology in forest soils has developed over a long time due to the non-intensive management of forest soils. Damage to forest soil occurs when there is logging activity, fire, or land use change. Some forest was used as productive land for example agroforestry and forest production. As with land use in agriculture, intensive management of forests can also reduce soil productivity. Inaccuracy forest land use would cause environmental or economic damage, so basic soil management data in forest areas is needed. However, the soil morphology of the Ayer Hitam Forest Reserve (AHFR) in Malaysia has never been observed. The objective of this study is to assess the soil characteristic and soil morphological properties of the AHFR . Studying the characteristics of soil morphology in toposequent conditions is necessary to find out the differences in soil from different heights and the effects of erosion, transportation, and deposition on the soil. This study was conducted in the AHFR , Puchong, Selangor Darul Ehsan , Peninsular Malaysia. Mapping of the area under investigation was carried out by conventional soil survey techniques with a physiographic approach using maps with a scale of 1:30,000. The results showed that AHFR has some different soil morphologic al characteristics and classification in subgroup among five different slope positions with similar soil order, which is a U ltisol soil. The soil in the AHFR is formed from highly weathered soil due to high rainfall in this location. Th e result s of this study are important for soil development, identification management, and land use priority such as erosion control on steep - slope forest areas, regeneration and reforestation, and it can also be used for forest education, practice, research , and training activities.

This study aimed to observe and compare the qualitative anatomical characteristics of compression (CW) , lateral (LW) , and opposite (OW) woods in the stem wood of Sumatran pine ( Pinus merkusii ) and Agathis ( Agathis loranthifolia ) . The anatomical characteristics were observed using optical microscopy and scanning electron microscopy. CW showed a gradual transition from earlywood to latewood in both species, circular tracheid shape, many intercellular spaces, irregular tracheid tips, helical cavities, and slit-like bordered pit s . CW of Sumatran pine showed an indistinct growth ring, while CW of Agathis showed a distinct growth ring. Helical ribs occurred only in CW of Sumatran pine. LW and OW showed an oval tracheid with an angular outline, regular tracheid arrangement, and tapered tracheid tips in both species. LW and OW showed mainly uniseriate bordered pits in Sumatran pine, while LW and OW of Agathis frequently showed multiseriate bordered pit s . CW, LW, and OW showed fusiform and uniseriate rays in Sumatran pine, while those of Agathis showed uniseriate rays. In conclusion, CW showed distinctive qualitative anatomical characteristics to LW and OW in both species, while LW and OW mainly showed similar characteristics. In particular, there were considerably distinctive characteristics between CW from both species. Keywords: Agathis, anatomical characteristics, reaction wood, Sumatran pine

While many studies have examined Forest Management Unit or Kesatuan Pengelolaan Hutan ( KPH) management in Indonesia, studies that focused on specific partnership policies in developing nature-based tourism in KPH remain understudied. This study offered a case of partnership in nature-based tourism development in the Mangunan area, KPH Yogyakarta, Indonesia. To understand to what degree the partnership benefits locals and forest areas, a triangulation approach includes secondary data collection, interviews, and field observations were employed. In the case considered, it is evident that the deliberative policies of KPH Yogyakarta foster social innovations in nature-based tourism development and serve the pathway in delivering simultaneous benefits for locals and forest areas. In drawing its conclusion, the study highlights that the nature-based tourism development in the Mangunan area has fostered locals’ roles in managing state-forest areas by which they generate numerous benefits. Furthermore, this study provides valuable insights that would allow us to better grasp the positive impacts of innovative policies in managing KPH .
