  • For the encapsulation of flavor compounds, maltodextrin (MD), gum arabic (GA) alkenylsuccinated modified starch (MS) and gellan gum were chosen for wall materials and their combination was optimized. Five fruit flavor compounds having boiling point of $90{\sim}200^{\circ}C$ were selected as core materials and their mixture was incorporated with rapeseed oil (flavor mixture to oil = 1 : 4). Flavor compound mixture to wall material ratio of 1 : 4 was selected, and the amount of maltodextrin was fixed to 30% of the wall material mixture. Gellan gum was selected as an additional wall material to increase emulsion stability. The optimum combination ratio of the wall material mixture for maximal total oil retention and minimal surface oil content is : 30.0% MD ; 26.4% GA ; 39.6% MS ; 4% gellan gum.

  • The effects of some hydrocolloids such as carboxymethylcellulose, xanthan gum, gum arabic, and sodium alginate, on quality attributes of rice cake (packsulki) were investigated. Fresh(F) and refrigerated(R) packsulkis were evaluated by sensory evaluation and with Instron Testing Mashine. The results of sensory evaluation indicated the differences among packsulkis with and without additive. Hardness of packsulkis increased markedly when refrigerated. Differences among R groups were much smaller compared to those among F groups. Textural characteristics measured by Instron also revealed the differences among the groups. They showed similar tendancy to those of sensory evaluation.

  • This study was carried out to investigate rheological properties of bread dough by adding hydrocolloids such as arabic gum, pectin and carboxyl methyl cellulose (CMC). 0.2% and 0.5% of each hydrocolloid were added to the dough. Farinograph, pH of dough, extensograph, fermometer and amylograph were analyzed. In farinograph, water absorption rate of dough was increased by adding hydrocolloids and the highest water absorption resulting in 70.8% was shown by adding 0.5% of CMC. Dough development time increased but stability decreased. pH of dough was lowered by adding hydrocolloids and pH of dough with 0.5% of pectin was the lowest. In extensograph, resistance of dough decreased but extensibility increased and R/E value lowered. In fermometer, $CO_2$ gas production increased and dough with 0.2% of CMC showed the largest gas production. In amylograph, initial gelatinization temperature increased by $0.5-1.5^{\circ}C$, but temperature for maximum viscosity was lowered by $1-1.5^{\circ}C$ and maximum viscosity was increased.

  • This article is concerned about a reason for which Cervantes participates an arabic author named Benengeli and morisco translator in his work instead of christian author. From the multi-cultural point of view, the time in which Don Qujote was published, belongs to the Golden Age. In other words, the society can not be supported by the ideology of Purity of Blood in that the morisco, converso (Christian Jewish) have been permitted to coexist in the name of christian proselyte or New Christian despite of invisible discrimination. An invisible discrimination is based on the prejudice and negative stereotype of Old Christian against the New Christian. Cervantes offers an o open space for readers to participate in the creative reading, giving up the absolute authority of author named Benengeli. The deep-rooted prejudice against morisco or muslim author makes the readers of Don Quijote do reinterpret the contents and have question about his sincerity. This disbelief is partly on the basis of hypothesis that Don Quijote would be passed on orally by an arabic or morisco. Leaving the hypothesis alone, Romance, festival performances of morisco or the aljamia literature in the Iberian Peninsula have the chivalry or knights of the Occident. The chivalry in Romance of morisco means that morisco would seek assimilation into the mainstream of Occidental Christian community. At the same time, morisco would be faced with the dilemma of loss of religious identity. But Taqiyya, islamic doctrine, offsets the dilemma between yearning to assimilate into mainstream and religious conscience of morisco in that Taqiyya permits morisco to convert to Christianity in case that they are in danger of life or the following risk. From this point of view, There is no room for doubt about the fact that Taqiyya contributed to social assimilation or multicultural society of the Iberian Peninsula. It has been a long time since a narrow-minded religious dogma and ideology became a anachronistic relic in multicultural society of Spain such as the Purity of Blood. From a relative viewpoint, Don Quijote provides a ground for the collective intelligence among christian, muslim(morisco) and converso through a liberal community between readers and authors who form a pluralistic society.

  • Western society has depreciated the Middle Ages as the 'Darkness'. However, if Islam, which led the medieval millennium, had not spread paper and art of papermaking, and Arabic translations to the Western countries, translating and interpreting Arabic manuscripts into Greek and Latin, Gutenberg's printing press, Reformation, and Renaissance could not take place. They were not destructors of ancient knowledge and civilization, but were the protagonists of restoration and resurrection. The base camp is the Mosque and Islamic library(the House of Wisdom), which was referred to as a Muslim community. This study traced Islamic libraries that emerged in the process of establishing the Islamic dynasties and controlling Arabian Peninsula, Africa, Iberian Peninsula. For this purpose, the Islamic library was divided into the caliph library led by the royal families, the public library attached to the mosques, and the private library established by the viziers and scholars, etc. Then, the researcher analyzed history and development, roles and functions, impact and Importance on human civilization, and stagnation and decline, focusing on major libraries that existed in the Islamic cities of Damascus, Mecca, Baghdad, Aleppo, Cordoba, Cairo, Fes, Tunis, etc.

  • This work provides a reliable and classified stocks dataset merged with Saudi stock news. This dataset allows researchers to analyze and better understand the realities, impacts, and relationships between stock news and stock fluctuations. The data were collected from the Saudi stock market via the Corporate News (CN) and Historical Data Stocks (HDS) datasets. As their names suggest, CN contains news, and HDS provides information concerning how stock values change over time. Both datasets cover the period from 2011 to 2019, have 30,098 rows, and have 16 variables-four of which they share and 12 of which differ. Therefore, the combined dataset presented here includes 30,098 published news pieces and information about stock fluctuations across nine years. Stock news polarity has been interpreted in various ways by native Arabic speakers associated with the stock domain. Therefore, this polarity was categorized manually based on Arabic semantics. As the Saudi stock market massively contributes to the international economy, this dataset is essential for stock investors and analyzers. The dataset has been prepared for educational and scientific purposes, motivated by the scarcity of data describing the impact of Saudi stock news on stock activities. It will, therefore, be useful across many sectors, including stock market analytics, data mining, statistics, machine learning, and deep learning. The data evaluation is applied by testing the data distribution of the categories and the sentiment prediction-the data distribution over classes and sentiment prediction accuracy. The results show that the data distribution of the polarity over sectors is considered a balanced distribution. The NB model is developed to evaluate the data quality based on sentiment classification, proving the data reliability by achieving 68% accuracy. So, the data evaluation results ensure dataset reliability, readiness, and high quality for any usage.

  • In this study, we conducted the adsorption equilibrium and batch experiments of dissolved organic carbon (DOC) in the wastewater by granular activated carbon (GAC). The components of organic compound were Beef extract (1.8 mg/L), Peptone (2.7 mg/L), Humic acid (4.2 mg/L), Tannic acid (4.2 mg/L), Sodium lignin sulfonate (2.4 mg/L), Sodium lauryle sulfate (0.94 mg/L), Arabic gum powder (4.7 mg/L), Arabic acid (polysaccharide) (5.0 mg/L), $(NH_4)_2SO_4$ (7.1 mg/L), $K_2HPO_4$ (7.0 mg/L), $NH_4HCO_3$ (19.8 mg/L), $MgSO_4{\cdot}7H_2O$ (0.71 mg/L), The adsorption characteristics of DOC in synthetic wastewater was described using the mathematical model through a series of isotherm and batch experiments. It showed that there was linear adsorption region in the low DOC concentration (0~2.5 mg/L) and favorable adsorption region in high concentration (2.5~6 mg/L). The synthetic wastewater used was prepared using known quantities of organic and/or inorganic compounds. Adsorption modelling isotherms were predicted by the Freundlich, Langmuir, Sips and hybrid isotherm equations. Especially, hybrid isotherm of Linear and Sips equation was a good adsorption equilibrium in the region of the both the low concentration and high concentration. In applying carbon adsorption for treating water and wastewater, hybrid adsorption equation plus linear equation with Sips equation will be a good new adsorption equilibrium model. Linear driving force approximation (LDFA) kinetic equation with Hybrid (linear+Sips) adsorption isotherm model was successfully applied to predict the adsorption kinetics data in various GAC adsorbent amounts.

  • The 3-omega (3-${\omega}$) method is utilized to measure the thermal conductivity of nanofluids. A metal line heater on a silicon nitride membrane bridge structure is microfabricated by a bulk silicon etching method. Localized measurement of the thermal conductivity within the nanofluids droplet is possible by the fabricated 3-${\omega}$ sensor. Time varying AC temperature amplitudes and thermal conductivities are measured to check the stability of the nanofluids containing multi-wall carbon nanotubes (MWCNTs). Stabilities of MWCNT nanofluids prepared with different chemical treatments are compared. Acid treated MWCNT showed best dispersion stability in water while MWCNTs dispersed in water with surfactants such as Gum Arabic and Sodium dodecyl benzene sulfate showed clear sign of gravity dependence.

  • Lipolytic characteristics of candia cylindracea lipase was studied by various triacylglycerols with different fatty acyl chains as substrate. The substrate was emulsified with gum arabic and the rate of hydrolysis was determined by pH stat method. The effects of gum concentration, pH, temperature, and $Ca^{2+}$ ion on the enzyme activities were examined. The results show that the effect of these factors are markedly depending on the structurla nature of substrates. The triolein was the best substrate among tested. Present study demonstrates that for characterization of lipolytic enzymes, it is critically important to select proper substrate and activator.r.

  • In this paper, we propose an automatic system that recognizes dynamic human gestures activity, including Arabic numbers from 0 to 9. We assume the gesture trajectory is almost in a plane that called principal gesture plane, then the Least Squares Method is used to estimate the plane and project the 3-D trajectory model onto the principal. An improved FNN model combined with HMM is proposed for dynamic gesture recognition, which combines ability of HMM model for temporal data modeling with that of fuzzy neural network. The proposed algorithm shows that satisfactory performance and high recognition rate.
