Lake Size

A 17.63 m long bore-hole core extracted from the deepest part of Lake Yamanaka, one of the Fuji-five Lakes at the northeasternfoot of Mount Fuji, central Japan, composed of sediment with intercalations of scoria fallout deposits. The sediment of the upper11.4 m was investigated for grain-size distribution by using a laser diffraction particle size analyser. The mean grain-size profileshowed various degrees of fluctuations, both short-and long-terms, and the size-frequency distribution revealed unimodal-trimodalmixing of sediments. Changes in lake size and water depth appear to be the main factors affecting the variability in the grain-sizedistribution and properties. The lake level appears low during 7000–5000 cal BP and 2800–1150 cal BP and relatively high during5000–2800 cal BP and 1150 cal BP– present.DOI: http://dx.doi.org/10.3126/bdg.v14i0.5437Bulletin of the Department of Geology Vol.14 2011, pp.35-42

SummaryA simple mathematical model of the distribution of potato tuber yield between size grades is presented. It has two parameters, μ, a measure of crop tuber size and σ, a measure of the spread of yield across size grades. The model is shown to be useful for the analysis of field experiments, the prediction and physiological study of tuber size distribution, and the economic analysis of management decisions. The model is applied to a variety of dataandthe practical control of tuber size discussed.

Abstract The gelation process of poly(vinyl chloride) (PVC) plastisol is very important to ensure the quality of the product and is affected by the type of resins, plasticizers, and other additives. In this study, the gelation process of the as-prepared PVC plastisol was characterized by measuring the evolution of vibrational viscosity with temperature or time using a vibrational viscometer. Furthermore, the effect of some commercial resins with different particulate morphologies on the gelation process was investigated by synchronously combining scanning election microscopy and laser particle size analyses. The results of this study proved that the particle size distribution and the aggregation degree of the secondary particles of a resin are the key factors affecting the gelation process. For the resin with bimodal particle size distribution, the closer the aggregation of the secondary particles, the slower the gel speed; however, an opposite behavior was observed for the resins with unimodal particle size distribution.

Experiments were conducted on some of factors affecting the polymerized particle size distribution in suspension polymerization of styrene. Polymerization experiments with styrene at 80 °C showed that the final polystyrene product size distribution is strongly affected by the stabilizer concentration, the type and the speed of impeller, and the hold-up fraction.

This study aims to investigate attributes of tempeh desired by consumer households, consumers satisfaction levels on tempeh, the pattern of tempeh demand, and factors affecting tempeh demand in Bandar Lampung City. This study is conducted in Bandar Lampung City. Data is collected in December 2016 to February 2017. The population in this study is household in Bandar Lampung City. The samples employed in this study are 75 households chosen by multistage random sampling method. The results showed that tempeh attributes  wanted by consumer households were cheap price, good taste, unique looks, good packaging, hygienic tempeh, quality standard, containing good nutrients, and accesibility location to purchase tempeh. Consumer households in Bandar Lampung City were satisfied by tempeh products. Tempeh demand patterns by consumer households in Bandar Lampung City were as follows: the average of tempeh purchases by household was 1,600 grams per week and the average of purchase frequency was 1.72 times per week. The total of tempeh consumption was 66.67 percent processed by frying, mostly be purchased at the market. Affecting factors on tempeh demand were price of tempeh, vegetable oil, wheat flour, and eggs.Key words: demand, consumer satisfaction, tempeh

The Stability

The most common method of biodiesel production is base catalyzed transesterification where alkaline materials, such as potassium hydroxide, are used as a catalyst. This paper presents a study of factors affecting biodiesel production from low free fatty acids (FFA) content waste vegetable oil through base catalyzed transesterification as well as the optimum reaction conditions. The optimum conditions were found to be a time of 60 min, catalyst loading of 1% of oil mass, mixing speed of 400 rpm and temperature of 65 °C. It also introduces a kinetic study of this reaction to determine the best model to fit the experimental data. First order model was found to be the best one to fit the early reaction stages while the second order model was the best to describe reaction kinetics in later stages. The stability of produced biodiesel was studied through determination of acid value and viscosity of stored biodiesel along three months.
