Background Using clinical judgment to diagnose dehydration can be highly subjective. To diagnose dehydration, it would be ideal to have an accurate, inexpensive, objective and easy-to-perform diagnostic tool. In cases of dehydration, plasma osmolality rises, causing an increase in antidiuretic hormone (ADH) secretion. The increased ADH reduces urine production and increases urine osmolality. Previous studies have show that urine osmolality correlates well to urine specific gravity. We investigated if urine specific gravity can be a reliable and objective detennination of dehydration status.Objective To assess the accuracy of using urine specific gravity as a diagnostic tool to determine dehydration status of children with diarrhea.Methods We conducted the study in the pediatric ward of Sardjito Hospital from September 2009 to December 2009. Using a refractometer we measured urine specific gravity from patients with diarrhea. This measurement was then compared to a standard of acute body weight loss, with dehydration defined as weight loss of 5% or more. The cut-off value for defining dehydration using specific gravity measurements was detennined by a receiver-operator curve (ROC).Results Out of 61 pediatric patients who were recruited in this study, 18 (30%) had dehydration as defined by a body weight loss of 5% or more. Based on the ROC, we determined the cut off  value for urine specific gravity to be 1.022. Using this value, urine specific gravity was 72% sensitive (95% CI 52 to 93), and 84% specific (95% CI 73 to 95) in determining dehydration status.Conclusion Urine specific gravity is less accurate than clinical judgment in determining dehydration status in children with diarrhea.

Abstract Weight loss, specific gravity and strength are traditional measures of how wood changes after fungal exposure. This study investigated the effects of fungal decay on properties of oriented strand board (OSB) made of aspen including weight loss, specific gravity, dowel-bearing strength, shear strength, and alkali solubility. Shear strength and alkali solubility were strongly correlated with specific gravity. In addition, X-ray densitometry and near-infrared (NIR) spectroscopy were used to study the decay process. X-Ray densitometry was used to assess localized density around the dowel-bearing embedment zone of a nail. A statistical model using the specific gravity directly under the nail from dowel-bearing strength tests as the explanatory variable had a higher coefficient of determination than models using the gross specific gravity of the sample. Predictive models using NIR spectro-scopy, in combination with multivariate statistical methods, showed promise as predictors of weight loss, shear strength, dowel-bearing strength, and solubility.

The response of potato (Solanum tuberosum L.) cultivars Russet Burbank and Kennebec to soil and fertiliser potassium (K) was studied on basaltic krasnozems of north-west Tasmania. Yield increases in response to fertiliser K were recorded at sites with up to 300-400 mg/kg of bicarbonate extractable soil K. The close correlation between relative yield and soil K indicated that soil K can reliably predict fertiliser requirements. Petiole K concentrations at early tuber set increased with fertiliser K at responsive sites; maximum yields were achieved with 12-14% petiole K for Kennebec and 11-13% for Russet Burbank. Petiole K concentrations provide an excellent indication of the K status of a growing crop. Tuber K concentrations increased with both soil and fertiliser K, and yields of 50-80 t/ha removed 180-380 kg K/ha in the tubers. At severely deficient sites specific gravity and crisp colour increased with low rates of fertiliser K, but the general trend was for fertiliser K to reduce specific gravity and crisp colour. Bruising susceptibility decreased with fertiliser K at some sites but the physiological disorder, 'hollow heart', was not influenced by fertiliser K. There were consistent differences between the 2 cultivars. Russet Burbank required higher soil K, had lower petiole and tuber K concentrations and removed less K in the marketable tubers.

The effects of preharvest, foliar applications of mefluidide (N-(2,4-dimethyl-5-(((trifluoromethyl)sulfonyl)amino)phenyl)-acetamide) to potato (Solanum tuberosum L.) plants on subsequent periderm development and on storage quality of Russet Burbank and Norchip tubers were investigated. Mefluidide application caused adnormal periderm development in tubers of both cultivars and resulted in increased tuber weight loss during storage due to enhanced water loss rather than to elevated respiration. Treatment with mefluidide 5 wk before harvest resulted in greater tuber weight loss in storage than treatment 7 wk before harvest. After ca. 26 wk storage, sucrose content generally increased in tubers from treated Russet Burbank plants but not in corresponding Norchip tubers. Despite a perceived periderm enhancement, the abnormal periderm development which increased water loss in stored tubers would suggest that mefluidide has little potential as a preharvest treatment to reduce tuber damage and improve storage of Russet Burbank and Norchip potatoes.Key words: Potato, mefluidide, storage, Russet Burbank, Norchip, periderm

Artificial graphite generally manufactured by carbonization sintering of shape-body of Kneaded mixture using granular cokes as filler and pitch as binder, going through pitch impregnation process if necessary and finally applying graphitization heat treatment. The effect of thermal oxidation with air or CO2 atmosphere on IG-11 graphite samples was investigated. The results show a localized oxidation process which progressively reveals the large coke particles with increasing overall weight loss in air. The surface of graphite was peel off which was not changed the specific gravity after air oxidation. However, the specific gravity of graphite continuously decreased by CO2 oxidation. Decreasing of specific gravity in the CO2 oxidation was because that CO2 gas ingress the surface to interior. The pore shape after the CO2 oxidation showed the longneck beakers.

Asphalt is a pavement material that works as an aggregate binder and filler Natural polymer in the form of cellulose from banana stem leaves has the potential to be used as an alternative material added on asphalt to increase the quality of asphalt itself. The reason for the use of cellulose from banana stem is because it is easy to get and can reduce waste of banana stem. The design of the specimens used pure asphalt pen 60/70 mixed with banana stems fiber powder. Percentage of additive material were 0%; 0.1%; 0.2%; 0.3%; and 0.4% of the asphalt weight. The specimens made for each physical asphalt test were three samples. The results of the analysis and discussion found that the additional banana stems fiber powder on the pure asphalt produced an increase in physical characteristics of asphalt. The optimal percentage of adding banana stems fiber powder was obtained at 0.1% percentage since all test values fulfilled the 60/70 asphalt requirement. The additional banana stems fiber powder of 0.1% resulted in a decrease in penetration value from 70.7 (0.1 mm) to 67.4 (0.1 mm), ductility value from 146 cm to 102.3 cm, weight loss from 0 , 14% to 0.09%, and the specific gravity from 1.042 to 1.037. The additional banana stems fiber powder with asphalt resulted in an increase of softening point from 44.2 º C to 44.7 º C, the viscosity value from 300.99 cst to 320.80 cst. Aspal merupakan bahan perkerasan jalan sebagai bahan pengikat dan pengisi antar agregat, sehingga aspal harus memiliki kemampuan dalam mempertahankan sifat fisiknya terhadap kelenturan dan kelekatannya. Polimer alam berupa selulosa dari pelepah batang pisang memiliki potensi dijadikan alternatif bahan tambah pada aspal untuk meningkatnya kualitas dari aspal. Pertimbangan penggunaan selulosa dari batang pisang dikarenakan mudah didapatkan dan dapat mengurangi limbah batang pisang dan menjadi bahan yang bermanfaat. Metode yang dilakukan untuk membuat aspal jenis baru ini dengan mempersiapkan bahan tambah berupa pelepah batang pisang menjadi serbuk serat. Rancangan benda uji menggunakan aspal murni pen 60/70 yang dicampur dengan bahan aditif dari serbuk serat pelepah batang pisang. Prosentase bahan tambah sebesar 0%; 0,1%; 0,2%; 0,3%; dan 0,4% dari berat aspal. Benda uji dibuat masing–masing sebanyak tiga sampel untuk setiap pengujian sifat fisik aspal. Hasil analisis dan pembahasan didapatkan bahwa penambahan serbuk serat batang pisang pada aspal murni menghasilkan peningkatan terhadap karakteristik sifat fisik aspal. Prosentase optimal penambahan serat batang pisang didapat pada prosentase 0,1%, karena semua nilai pengujian memenuhi persyaratan aspal 60/70. Penambahan serbuk serat batang pisang sebesar 0,1% mengakibatkan penurunan nilai penetrasi dari 70,7 (0,1 mm) menjadi 67,4 (0,1 mm), nilai daktilitas dari 146 cm menjadi 102,3 cm, kehilangan berat dari 0,14% menjadi 0,09%, dan berat jenis dari 1,042 menjadi 1,037. Penambahan serbuk serat batang pisang dengan aspal mengakibatkan kenaikan titik lembek  dari 44,2ºC menjadi 44,7ºC, nilai viskositas dari 300,99 cst  menjadi 320,80 cst. Penambahan serbuk serat batang pisang pada aspal mengakibatkan penurunan nilai penetrasi dan nilai daktilitas serta meningkatkan nilai titik lembek aspal sehingga aspal lebih tahan pada temperatur yang lebih tinggi.

The objective of this study was to evaluate the internal quality and lipid oxidation of eggs coated with a carnauba wax-based product at different concentrations and stored for up to 28 days under two temperatures. For analysis of internal quality, the eggs were assigned to a completely randomized 3 x 4 factorial design (uncoated eggs (control); eggs coated with carnauba wax at 12% concentration (Aruá®); eggs coated with carnauba wax at 15% concentration (Aruá®); four storage periods - 7, 14, 21, and 28 days). Fifteen eggs from each treatment were evaluated in each storage period, with each egg representing one replicate, i.e., 300 eggs per storage temperature (10 and 25°C). Egg weight loss, yolk percent (%), albumen percent (%), Haugh unit, yolk index, and specific gravity were calculated. Lipid oxidation of the egg yolk was measured by thiobarbituric acid reactive substances (TBARS), using 10 eggs at time 0 (fresh) and 30 eggs in each storage period (7, 14, 21, and 28 days), in triplicate, under only one storage temperature (25°C). A total of five pools, consisting of two eggs each, were used for each treatment. Each pool was considered a replicate, and each treatment consisted of five replicates. The weight loss of the eggs stored at 10°C and 25°C during the storage period was, on average, 46.1% and 37.3% lower for the eggs coated with carnauba wax than in uncoated eggs, respectively. Overall, coated eggs, regardless the concentration of the wax (12 or 15%) had higher Haugh units, specific gravity, and yolk index than uncoated eggs, in both temperatures (10 and 25°C). Uncoated and coated eggs showed similar lipid oxidation values regardless of the storage period. On the other hand, eggs coated with solutions containing 15% wax showed less oxidation than eggs coated with 12% wax. The coating of commercial eggs with carnauba wax, both at concentrations of 12 and 15%, was effective in maintaining their internal quality during storage at both storage temperatures (10 and 25°C). Eggs stored at 25°C had lower quality traits during storage compared with eggs kept under refrigeration. Coating eggs with wax did not minimize the oxidative processes in the egg yolk.
