Habitat of Asian giant honeybee (Apis dorsata) and the forest that surround it play an important role for the development of bees. For local, honey gathered from the bees has important role in enhancing people`s live hood. However, studies examine the interaction between the bees and its vegetation is limited. The objection of this study were to (1) determine the number of the sialang trees and (2) to eamine structure of vegetation along the Indragiri river, Riau. The data were collected using the observation method by establishing many observation plots. The data were processed and analyze using quantative descriptive. The results showed that the structure of forests along the Indragiri river are consisted of several types of sialang trees, namely jelemu, arau, and stone wood. The diversity of plants is considerably high, such as Melastoma malabatrichum, rubber, ferns, acacia, and rattan at the seedling level and Macaranga sp, durio sp, rubber and meranti at the weaning level. The vegetation is considered still in good condition for bees` hive. Forest vegetation is dominated by the types of meranti, rubber, and the araceae family which can be used for either habitat or bee forage for bees.

The typologies of landscapes of individual states that have ratified the European Landscape Convention do not include mountain pasture landscapes. Pasture landscapes in the Carpathians are preserved in a relatively good condition, although their spatial extent has considerably shrunk over the last few decades. The article demonstrates that mountain meadows and glades in the Carpathians meet all the conditions that allow them to be classified as a type of landscape, and thus they should be included in national typologies of landscapes. Firstly, they constitute a set of natural (non-forest vegetation) and anthropogenic (traditional shepherding buildings) objects. Secondly, they are a dynamic system in which natural, social and economic processes take place. They are also a source of stimuli, affecting different human senses and values and are a system that provides various real and potential services. The inclusion of mountain pasture landscapes in national typologies may provide a stronger basis for their protection.

Partial Intestinal Obstruction

Total colonic aganglionosis (TCA) extended to the ileum is seen quite rare among infants with Hirschsprung's disease. Type and timing of definitive surgery in these patients are controversial. This report was presented to discuss the management of two siblings with TCA. Case 1: A two-day-old girl was operated for partial intestinal obstruction. During laparotomy, serial frozen biopsies proved TCA extended to the terminal ileum and a loop ileostomy was performed. At five months of age, a modified Duhamel-Martin procedure without protective ileostomy was performed. An endo-GIA stapler was transanally used for colo-ileal anastomosis. She is doing well for the last five years. Case 2: A one-day-old boy admitted to the hospital with similar findings to his sister. Frozen biopsies during first laparotomy proved that majority of ileum and entire colon was aganglionic and a proximal ileostomy was performed. At 10 months of age, he underwent a similar Duhamel-Martin operation. He is in a good condition for the last four years. Conclusion: In infants, our modification on Duhamel-Martin procedure, which is based on the use of an endo-GIA stapler transanally for colo-ileal anastomosis without protective ileostomy, may be utilized as an alternative method in the definitive treatment of patients with TCA.

The financial statements serve as a benchmark in assessing the financial performance of the company as the basis for making business decisions. The motivation in conducting this research is to support previous research to see the development condition of one of the oil palm plantation companies. The purpose of this study is to assess the financial performance by using financial ratio analysis and horizontal analysis. The method used in this research is Quantitative Descriptive with analysis design using Term series Analysis. The result of the research based on financial ratio analysis shows the liquidity ratio and solvency ratio in good condition, while the activity ratio and profitability ratio are not good because it is below the industry average of similar companies. Based on horizontal analysis, financial performance fluctuated and influenced internal and external factors such as operational performance and the average price of world palm oil. The limitations of this study are using only two analytical tools and financial statements analyzed only the balance sheet and income statement.

This paper presents the findings of the stability, thermal conductivity and viscosity of CNTs (doped with 10 wt% graphene)- TiO2 hybrid nanofluids under various concentrations. While the usage of cutting fluid in machining operation is necessary for removing the heat generated at the cutting zone, the excessive use of it could lead to environmental and health issue to the operators. Therefore, the minimum quantity lubrication (MQL) to replace the conventional flooding was introduced. The MQL method minimises the usage of cutting fluid as a step to achieve a cleaner environment and sustainable machining. However, the low thermal conductivity of the base fluid in the MQL system caused the insufficient removal of heat generated in the cutting zone. Addition of nanoparticles to the base fluid was then introduced to enhance the performance of cutting fluids. The ethylene glycol used as the base fluid, titanium dioxide (TiO2) and carbon nanotubes (CNTs) nanoparticle mixed to produce nanofluids with concentrations of 0.02 to 0.1 wt.% with an interval of 0.02 wt%. The mixing ratio of TiO2: CNTs was 90:10 and ratio of SDBS (surfactant): CNTs was 10:1. The stability of nanofluid checked using observation method and zeta potential analysis. The thermal conductivity and viscosity of suspension were measured at a temperature range between 30˚C to 70˚C (with increment of 10˚C) to determine the relationship between concentration and temperature on nanofluid’s thermal physical properties. Based on the results obtained, zeta potential value for nanofluid range from -50 to -70 mV indicates a good stability of the suspension. Thermal conductivity of nanofluid increases as an increase of temperature and enhancement ratio is within the range of 1.51 to 4.53 compared to the base fluid. Meanwhile, the viscosity of nanofluid shows decrements with an increase of the temperature remarks significant advantage in pumping power. The developed nanofluid in this study found to be stable with enhanced thermal conductivity and decrease in viscosity, which at once make it possible to be use as nanolubricant in machining operation.

A New Species

Abstract—A new species of Eugenia from the Atlantic forest of Brazil is described and illustrated. Eugenia flavicarpa is restricted to the Floresta de Tabuleiro (lowland forests) of Espírito Santo state and is nested in Eugenia subg. Pseudeugenia. Considering all other species of the subgenus that occur in forest vegetation types of the Atlantic forest phytogeographic domain, Eugenia flavicarpa can be distinguished mainly by the combination of smooth leaves with indumentum on both surfaces, with two marginal veins, usually ramiflorous inflorescences, pedicels 4.5‐9.7 mm long, flower buds 3.5‐4 mm in diameter, and by the calyx lobes that are 2‐3 mm long with rounded to obtuse apices. Morphological analyses were performed to explore the significance of quantitative diagnostic features between the new species and the closely related species, Eugenia farneyi. Notes on the habitat, distribution, phenology, and conservation status of Eugenia flavicarpa are provided, as well as a key for all species of Eugenia subg. Pseudeugenia from forest vegetation of the Atlantic forest phytogeographic domain.
