A complexidade do planejamento do transporte florestal de madeira levou ao desenvolvimento de um método que auxiliasse na determinação das melhores rotas a serem seguidas por caminhões, para se conseguir um menor custo possível para um máximo volume de madeira posto pátio. Baseando-se na solução do problema do transporte através da programação linear, o método descrito neste trabalho permite, em uma situação de diversas origens e um único destino, análises quanto ao número ideal de viagens, carga ótima por veículo, menor custo por unidade de volume e quilometragem máxima mensal. Os resultados obtidos nos estudos de casos mostram adequação econômica do método de planejamento do transporte por programação linear, havendo um aumento de 22,70% no volume de madeira posto pátio e uma redução de 18,33% no custo por estéreo posto pátio. FORESTRY TRANSPORTATION COSTS MINIMIZATION USING LINEAR PROGRAMMING Abstract The complexity of planning the forest transport leads to developing of a method to aid in the determination of the best routes to be used for trucks, aiming to the lower cost possible for de maximum volume of wood transported. Aiming to the solution of this problem of transport trough linear programming, the method reported in this work allows in situation of several wood origins and just one destine, analyzes on the ideal number of traveling, the optimum truck loading, the lower cost per wood unit volume and the maximum monthly truck mileage. The results obtained in this case study showed economic adequation of the method to transport planning using linear programming, accounting the increase of 22,7% in the wood volume delivery and reduction of 18,33% in the cost on the same number of trucks.

Abstract Freshwater crustaceans are distributed throughout the montane and lowland areas of Colombia, and are therefore a useful indicator group for how aquatic species will respond to climate change. As such, metabolic determination of physiological performance was evaluated for the Colombian pseudothelphusid crab, Neostrengeria macropa (H. Milne Edwards, 1853), over a temperature range inclusive of current temperatures and those predicted by future scenarios in the plateau around the city of Bogotá, namely from 8 °C to 30 °C. The performance results mostly aligned with previous exploratory behavioral determination of the ideal temperature range in the same species, although the metabolism increased at the highest temperature treatments, a point when exploratory behavior declined. These results indicate that this species of montane crab behaviorally compensates for increased thermal stress by decreasing its physical activity, which could have negative predator-prey consequences with changes to community structure as different species undergo climate-mediated geographic range shifts in the region. As this species is endemic to the plateau surrounding Bogotá, it also experiences a number of other stressors to its survival, including infrastructure development and invasive species.

Density functional theory is used to determine the possible crystal structure of the CaSiO3 perovskites and their evolution under pressure. The ideal cubic perovskite is considered as a starting point for studying several possible lower-symmetry distorted structures. The theoretical lattice parameters and the atomic coordinates for all the structures are determined, and the results are discussed with respect to experimental data.

Scale-free networks have several favorable properties as the topology of interconnection networks such as the short diameter and the quick message propagation. In this paper, we propose a method to construct scale-free networks in a semi-deterministic manner. The proposed algorithm extends the Bulut's algorithm for constructing scale-free networks with designated minimum degree k and maximum degree m, in such a way that: (1) it determines the ideal number of edges derived from the ideal degree distribution; and (2) after connecting each new node to k existing nodes as in the Bulut’s algorithm, it adjusts the number of edges to the ideal value by conducting add/removal of edges. We prove that such an adjustment is always possible if the number of nodes in the network exceeds [Formula: see text]. The performance of the algorithm is experimentally evaluated.

Lowlands represent a significant portion of agricultural areas in the world. Thus, understanding the spatial variability of the chemical and granulometric characteristics of hydromorphic soils can contribute to improving soil management and fertility. The objective of this work was to characterize spatial dependence, spatialized chemical attributes, granulometry, and the ideal number of samples in irrigated hydromorphic soil. Soil sampling was conducted in a grid of 10x10 m, in the layers of 0–0.1 and 0.1–0.2 m, totalling 432 composite samples. The evaluated attributes are as follows: pH in water, H+Al, SOM, Ca, Mg, Al, P, K, CTC, V%, Cu, Fe, Zn, Mn, clay, silt, and sand. The texture of the area was classified as loamy–sandy and free in the 0–0.1 and 0.1–0.2 m layers, respectively. The coefficient of variation of the attributes ranged from 2.71% (0–0.1m) to 149.07% (0.1–0.2m). All the attributes studied exhibited moderate to strong spatial dependence. The sample grid with a sampling interval of 20 m referring to the 0–0.1 m layer proved to be adequate. The ideal number of simple samples per composite is 19 for granulometry and macronutrients, and 28 for the micronutrients in the 0–0.1 m layer.

Abstrak This paper will explore aspects of research methodology of exegesis written by Aksin Wijaya related to methods nuzuli ala Muhammad Izzat Darwazah. For that, the focus of this discussion is the methodology of his research in his own book of under title Sejarah Kenabian Dalam Perspektif Tafsir Nuzuli Muhammad Izzat Darwazah, finding out how people review mufassir. Specifically, the methodical determination of the previous his experienced has moved soon of orientation from the critical to the descriptive while facing of four books, namely: Tafsir al Hadith, 'Ashr al Nabiy wa Biatuhu Qabla al Bi'tsah, Sirah al Rasul; Suwar Muqtabasah min al Qur'an, and ad Dustur al Qur'an fi Su'uni al Hayat works of thinkers and historians. From his reading, he at least analyzes his views into two important parts, namely; 1) the interpretation method of nuzuli and the ideal concept it contains, 2) it then draws it into the realm of pre-Islamic, personal and family life of the prophet Muhammad, to the condition of the people of prophetic era through the perspective of nuzuli Izzat Darwazah exegesis. According to the reviewer, there are other research elements in writing the work of the exegesis, namely some models of research methods of interpretation at once, such as: comparative research, character research, and thematic-nuzuli research. Whereas although placed more as an overview of nuzuli interpretation, at least he invites readers, especially in Indonesia to re-read the tafsir nuzuli treasury and see which is as worthy to be developed in the turats of Islam Nusantara. Abstrak Tulisan ini hendak menelusuri aspek metodologi penelitian tafsir yang dilakukan oleh Dr. Aksin Wijaya terkait metode nuzuli ala Muhammad Izzat Darwazah. Untuk itu, fokus dari pembahasan ini adalah tentang metodologi penelitiannya dalam buku berjudul Sejarah Kenabian Dalam Perspektif Tafsir Nuzuli Muhammad Izzat Darwazah untuk mengetahui bagaimana orang mengkaji mufassir. Dimana secara khusus mulai penentuan metodis dari sebelumnya ia mengalami pergeseran orientasi dari kritis ke deskriptif dalam menghadapi empat kitab hasil perburuannya, yaitu: Tafsir al Hadits, ‘Ashr al Nabiy wa Biatuhu Qabla al Bi’tsah, Sirah al Rasul; Suwar Muqtabasah min al Qur’an, dan ad Dustur al Qur’an fi Su’uni al Hayat karya tokoh pemikir dan sejarawan. Dari pembacaannya tersebut, ia setidaknya menganalisa pandangannya menjadi dua bagian penting, yaitu; 1) metode tafsir nuzuli dan konsep ideal yang dikandungnya, 2) kemudian ia menariknya ke ranah kehidupan masyarakat pra-islam, pribadi dan keluarga nabi Muhammad saw, hingga kondisi masyarakat era kenabian melalui perspektif tafsir nuzuli Izzat Darwazah. Pun demikian, menurut penulis ada unsur penelitian lain dalam penulisan karya Aksin tersebut, yaitu beberapa model metode penelitian tafsir sekaligus, seperti: penelitian perbandingan, penelitian tokoh, dan penelitian tematik-nuzuli. Dimana walaupun diletakkan lebih sebagai gambaran umum tafsir nuzuli, setidaknya ia mengajak pembaca khususnya di Indonesia untuk meneelaah kembali khazanah tafsir nuzuli dan memandang mana yang sekira layak untuk dikembangkan dalam turats Islam ke-Indonesia-an.
