Estimation of Shelf Life of Mango Juice Produced Using Small-Scale Processing Techniques

The objective of this study was to estimate shelf life of mango juice produced using small-scale processing techniques. Juice was processed and packaged in 80 plastic bottles and stored at 13 oC and 30 oC. At each temperature, 20 bottles had preservative (0.5 mg/l sodium benzoate) and 20 bottles had no preservative. The juices were analyzed for pH, vitamin C, sensory attributes and microbial load at two week intervals for six weeks. From week 2 to week 6, juices stored at 30 o C had lower pH values (3.15 – 2.80 with preservative, 3.60 – 2.6 without preservative) than juices stored at 13 o C (4.20 - 3.80 with preservative, 4.15 - 3.70 without preservative ) and the differences were significant (p<0.05). At 6 weeks, vitamin C loss was highest (79%) in juice without preservative stored at 30 o C, followed by juice stored at 30 o C with preservative (71.43%). The loss was lowest (26.98%) in juice with preservative stored at 13 o C. Significant differences (p<0.05) in color were observed at week 6 between juices stored at 13 o C (4.5 with preservative and 4.66 without preservative) and 30 o C (5.02 with preservative and 7.00 without preservative). Juices stored at 30 o C were rated ‘bad’ from week 2, in smell (5.91 and 6.25) and taste (5.66 and 6.91) while at that time, juices stored at 13 o C were rated ‘almost similar’ to fresh juice in smell (4.25) and taste (4.25 and 4.58). Storage at 13 o C with preservative resulted in lowest bacteria (2.04 x 10 4 CFU/ml) and yeast and mold (1.72 x 10 4 CFU/ml) counts whilst highest bacteria (2.10 x 10 8 CFU/ml) and yeast and mold (1.96 x 10 8 CFU/ml) counts were observed in juices stored at 30 o C without preservative. The shelf life was estimated based on taste and smell as 2 weeks and 4 weeks for juices stored at 30 o C and 13 o C, respectively. Chilling combined with use of preservative slowed down rate of vitamin C loss, deterioration of sensory attributes and microbial growth.
The Calming Effect of Imee Ooi's Buddhist Music: from Mantra to Music and Meditation

Past researchers explain how Buddhist music has gone through three stages developing from chant, to devotional song, to commercial music. Among the many composers of Buddhist music, Imee Ooi is a wellknown Malaysian composer who has composed and produced thirty albums to date, highlights being: Siddhartha, Above Full Moon, The Chant of Metta, Heart Sutra and Jewel of Tibet. The composer has a reputation for producing her own Buddhist mantra music that is believed to have a calming effect on listeners. This study looks into the context of Buddhist music and examines its effect on listeners. Methods that are both qualitative and quantitative in nature include analysis, interview and virtual ethnography. The song composed on the mantra Om Mani Padme Hum was selected for musical analysis to shed light on how Ooi ingeniously combines text into a musical structure that contributes to a calming and meditative effect.
Comparision of Iris Identification by Using modified SIFT and SURF keypoint Descriptor

A wide variety of systems require reliable personal recognition schemes to either confirm or determine the identity of an individual requesting their services. The purpose of such schemes is to ensure that only a legitimate user, access the rendered service. A biometrics system is essentially a pattern recognition system, which makes a personal identification by determining the authenticity of a specific physiological or behavioral characteristic possessed by the user. Iris serves as one of the excellent biometric traits due to the stability and randomness of its unique features. After localization of the iris, Scale Invariant Feature Transform (SIFT) is used to extract the local features. But SIFT is found out to be computational complex.So in this paper another keypoint descriptor ,Speeded Up Robust Features (SURF), is tested and then modified which compare the performance of different descriptor and hence gives promising results with very less computations. We finally carry out a comparision of both the descriptors performance wise.

A Review of the Hyporheic Zone, Stream Restoration, and Means to Enhance Denitrification

The hyporheic zone is the subsurface area below and adjacent to a stream where groundwater mixes with stream water, through vertical, lateral, and longitudinal flows. The hyporheic zone connects the stream to uplands and other terrestrial environments. It is a zone of distinct faunal communities, high biological diversity and ecological complexity, and is the site of chemical processing and transformations of ground- and stream waters. The hyporheic zone is important to the overall ecosystem ecology of the stream, and it can influence stream water chemistry. Flows, reactions, and biota in the hyporheic zone are heterogeneous and patchy, making it difficult to clearly describe the ecotone in a straightforward, general way. Nitrogen processing, especially denitrification, appears to be widespread in the hyporheic zone. The hyporheic zone, as with most aquatic systems, is often impacted by human activities. Stream restorations rarely consider potential effects on the hyporheic zone, but careful project choices can enhance the condition of the hyporheic zone, and so increase uptake of nitrogen by stream-associated environments as partial mitigation of continuing and increasing releases of reactive nitrogen, potentially reaping short-term benefits to estuarine environments that may not be as quickly realized from source control measures.
Radial velocities of HIPPARCOS southern B8-F2 type stars

Radial velocities have been determined for a sample of B8-F2 type stars observed by the Hipparcos satellite. Observations were obtained within the frame- work of an ESO key-program. Radial velocities have been measured using a cross-correlation method, the templates being a grid of synthetic spectra. The obtained precision depends on eective temperature and projected rotational velocity of the star as well as on a possible asymmetry of the correlation peak generally due to secondary com- ponents. New spectroscopic binaries have been detected from these asymmetries and the variability of the mea- sured radial velocity. Simulations of binary and triple sys- tems have been performed. For binaries our results have been compared with Hipparcos binary data. Adding the variable radial velocities, the minimum binary fraction has been found 60% for physical systems. Radial veloc- ities have been determined for 581 B8-F2 stars, 159 being new. Taking into account published radial velocities, 39% south A-type stars with V magnitude lower than 7.5 have a radial velocity.
COMPARISON OF THE SOMATIC STATE AND THE LEVEL OF MOTOR PERFORMANCE OF BOYS BETWEEN THE AGES OF SEVEN AND FIFTEEN IN THE OLOMOUC REGION (CZECH REPUBLIC) AND IN OPOLE (POLAND)

BACKGROUND: Recent years have seen a decrease in habitual movement activity in children and youth, which is being replaced by the predominance of a sedentary lifestyle. A reflection of these negative trends is also seen in the decrease in motor performance. OBJECTIVE: The aim of this research is to analyze the level of the motor skills of contemporary 7 to 15 year olds in Olomouc and in Opole and to compare the physical parameters of Olomouc and Opole boys with the 6th Nation- Wide Anthropological Survey of Children and Adolescents 2001 Czech Republic (the 6th CAV 2001). METHODS: The research was carried out in both the Olomouc (695 boys) and Opole (313 boys) regions. For the diagnostics of the level of the motor performance of the boys, standardized motoric tests were used: the standing long jump with legs together, one-minute sit-ups, the 4 × 10 meter shuttle run, and throwing a medicine ball using both hands, as well as the testing battery UNIFITTEST (6-60). For the statistical evaluation of the results, Student's t-test, Z-scores and the non-parametric χ^2-test were used. RESULTS: The results have shown that, in height and weight, both boys from Olomouc and from Opole are in accordance with parameters, which correspond also to the reference data of the 6th CAV 2001. An identical performance level was reached by both sets of boys in the 4 × 10 m shuttle run and in the standing long jump with legs together. In throwing the medicine ball with both hands, the Olomouc boys scored lower than the boys from Opole. During the period of their earlier school years, Olomouc boys scored higher in the one-minute sit-up test. The evaluation of individual motoric performance of boys in accordance with the testing battery UNIFITTEST (6-60) showed overall that 39% of the Olomouc boys and 42% of the Opole boys had less than average or even below average motoric performance levels. A comparison of the tested results of contemporary Olomouc and Opole boys with referential data for the Olomouc boys dating to 2001 and 2002 indicated a decrease in the speed, endurance and strength of their abdominal musculature and the dynamic-explosive capability of their upper and lower extremities. CONCLUSIONS: The decrease in the motoric performance level of Olomouc and Opole boys probably reflects a decrease in habitual movement activity and the prevalence of a sedentary lifestyle.
Voltage source active power filter, based on multi-stage converter and ultracapacitor dc-link

A multi-stage inverter using three-state converters is being analyzed for active filter and static var compensator applications. Each phase of the converter is composed of four three-state converters, all of them connected to the same dc link and its output connected through output transformers scaled in power of three. The filter can compensate load currents with high harmonic content and low power factor, obtaining sinusoidal currents from the source. A 1F ultracapacitor is used in the dc link, making it possible to obtain a very stable voltage at the dc bus, even with highly contaminated currents. This high capacity also makes it possible to continue feeding the contaminating load during a voltage dip. The capacitor voltage is controlled simply by changing the phase angle of the converter, and thus changing the amount of active current flowing to and from the converter. The control is implemented with a non-linear PI gain and a modulation control to maintain a stable ac voltage during dc voltage drops. The great advantage of this kind of converter is the minimum harmonic distortion obtained. Simulation results for this application are shown and compared with similar results obtained with conventional PWM converters.
Imparting Superhydrophilicity to Diamond-Like Carbon by Plasma Surface Treatment Technique

The surfaces of medical materials are coated with polymer molecules or drugs in order to functionalize the surfaces in ways such as imparting biocompatibility. However, in the case where the medical materials are inorganic, there is the problem that they will have poor adhesiveness to polymers and be liable to peel. For coronary artery stents, the authors succeeded in developing a method of rendering a diamond-like carbon (DLC)
kW-class picosecond thin-disc prepulse laser Perla for efficient EUV generation

Abstract. The technology for extreme ultraviolet (EUV) lithography sources is maturing. Laser produced plasma (LPP) sources with usable power >100 W have been used in high-volume manufacturing (HVM) applications, and 250-W sources are expected to be introduced in HVM soon. However, a further increase of power and cleanness may benefit a powerful picosecond (ps) laser in the near-infrared and wavelength converted spectral region. The HiLASE Centre has been working in thin-disc laser technology and has demonstrated a 0.5-kW platform Perla-C based on a very compact Yb:YAG regenerative amplifier. 100-kHz ps operation has been achieved with a fundamental spatial mode and excellent long-term pointing and energy stability. It is reported on a thin-disc-based ps Yb:YAG solid-state laser technology platform Perla developed in the Czech Republic and the present performance of delivering >4 mJ, <2-ps pulses at a 100-kHz repetition rate with the potential to be upgraded to 1 kW of average power and 1-MHz pulse repetition rate. The ps laser extendibility is important for kW-class LPP sources and controlled free electron laser EUV sources in 10-kW power region.

Information on the distribution of Cephalopod fauna was collected through 45 deep-trawl surveys carried out on the commercial trawl fishery waters (between 20 and 200 m) between March 2004 and May 2005. During the study, a total of 1101 individuals belonging to eight species; two cuttlefishes, two squids and four octopods, were recorded. Mean value of dorsal mantle lengths and body weights of the captured species were; 10.74 ± 0.10 cm and 126.42 ±3.24 g for Sepia officinalis, 4.2 cm and 4.68 g for Sepia elegans, 15.3±0.42 cm and 87.68 ±6.35 g for Loligo vulgaris, 10.93 ±0.28 cm and 48.17 ±4.52 g for Illex coindetii, 8.08 ±0.13 cm and 99.17 ±4.01 g for Eledone moschata, 13.5 cm and 281.46 g for Eledone cirrhosa, 10.25±0.45 cm and 370.33 ±53.89 g for Octopus vulgaris, 12.71±0.64 cm and 405.59 ±51.69 g for Octopus macropus. In addition the present study also provides information on dorsal mantle length – body weight relationship and biology of the species found in this particular area.
Intercultural interaction and "situational places": a perspective for urban cultural geography within and beyond the performative turn

With the performative turn in social sciences and the humanities the concept of performance has arrived in human geography. Performance denotes an understanding of social actions and practices as consti- tutive for non-representational realities. This paper looks at the relationship between places and performance especially in urban geography and develops the new term "situational place" to grasp the increasing phe- nomenon of (intercultural) encounters in the cities of modern world society. "Situational places" are situated performances of these (intercultural) interactions between strangers in cities of the contemporary world so- ciety. With the aid of performance theory the influence of the omnipresent interactions between strangers in cities on urban space is conceptualized. Therewith, we hope to present some fruitful theoretical and empirical possibilities for a cultural urban geography within and beyond the performative turn. In contemporary human geography many di erent theoreti- cal turns are discussed. The spectrum ranges from the lin- guistic to the somatic, from the spatial to the performative turn. Most of these theoretical turnarounds could be sub- sumed under the broader umbrella of the cultural turn. In this paper we understand "turn" as a metaphor for a move- ment because it signals and is a sign for the eternal motion contained in human geography. A scholastic fixing of theo- retical concepts in human geography is in many accounts im- possible because of its openness and conceptual complexity. It may well be argued that it is exactly this conceptual flexi- bility and openness, the constant ability to transgress bound- aries, that characterizes human(e) geography as a discipline beyond "disciplination". The di erent turns which are dis- cussed in recent human geography could be considered as empirical evidence of sorts for this theoretical thesis. Within this broad field of di erent turns the argument of this paper focuses on one very specific problem: the implications of the performative turn for urban geography or cultural urban geography. Because the performative turn gives space for

One Pot Synthesis of Polyhydroquinolines Catalyzed by Sulfonic Acid Functionalized SBA-15 as a New Nanoporous Acid Catalyst under Solvent Free Conditions

Sulfonic acid functionalized SBA-15 (SBA-Pr-SO3H) as a new nanoporous acid catalyst was used in the one-pot synthesis of polyhydroquinolines derivatives via the Hantzsch four component condensation reaction of aldehydes, β - ketoesters, dimedone and ammonium acetate under solvent free conditions with short reaction time in excellent yields. SBA-Pr-SO3H was proved to be an efficient heterogeneous nanoporous solid acid catalyst (pore size 6 nm), which could be easily handled and removed from the reaction mixture by simple filtration, and also recovered and reused without loss of reactivity.
Estimadores de parámetros genéticos para características de crecimiento predestete de bovinos. Revisión

En la presente revision, se presentan 2,689 estimadores reportados en la literatura para cinco parametros geneticos y tres caracteristicas de crecimiento de bovinos. Estos estimadores provinieron de 89 grupos raciales localizados en 38 paises. La media, el rango y el numero de estimadores fueron calculados para cada parametro genetico por caracteristica. Tres cientos treinta y siete (337) articulos publicados en la literatura fueron usados para esta revision. Para peso al destete, las medias de los estimadores de heredabilidad directa, heredabilidad materna, correlacion genetica entre efectos directos y maternos, y heredabilidad total fueron: 0.27, 0.17, -0.23 y 0.25. Los estimadores de parametros geneticos variaron grandemente para cada caracteristica. Los rangos de los estimadores fueron de: -0.01 a 0.95, 0.00 a 0.76, -1.00 a 1.00, y de 0.01 a 0.81, respectivamente. Para peso al destete, las medias de los estimadores de heredabilidad total para Angus, Charolais, Brahman, Hereford, Limousin, Nelore y Simmental fueron, en general, similares. Para peso al destete, la media de los estimadores de heredabilidad directa obtenidos mediante el metodo de correlacion entre medios hermanos paternos tendio a ser mas grande que las medias de los estimadores de heredabilidad directa obtenidos con modelos animal, semental y semental-abuelo materno. Las medias de los estimadores de heredabilidad directa y de heredabilidad materna indican que el genotipo del becerro fue mas importante que el genotipo de la vaca para determinar caracteristicas de crecimiento predestete. Sin embargo, las medias de los estimadores de heredabilidad total confirman que la seleccion podria ser efectiva para mejorar dichas caracteristicas
CFD Model Based Comparison of Mixing Efficiency of

The efficient blending and mixing of liquids are very important in most industrial technologies. Mixing is often carried out in tanks, reactors, or mixing apparatuses. Impellers are widely used in many industrial processes ranging from mining through hydrometallurgy to complex processes based on chemical reactions (e.g. fermentation, wastewater treatment, polymerization, crystallization). Mixing can be created in mechanical way by rotary elements on a shaft, or in pneumatically way by high-speed fluid flow. The quality of mixing has huge affect on the rate of transport processes (energy and/or mass) and on the reaction rate too in a chemical reactor. The mixing also contributes to the evaluation of the effects of the optimal operating parameters. The required power and the flow pattern in a vessel depend on the impeller geometry. In the literature, there are only recommendation and no indices to help choosing an impeller for a defined mixing task. And that is not possible to optimize the revolution per minutes at mixing element that have the same design. The primary goal of our research is to create a measure for quantitative characterization of the level of homogeneity in a stirred system resulted by different impeller geometries and rotating speed, and to compare the power consumptions.

Eggshells – assisted hydrolysis of banana pulp for biogas production

In this study, pretreatment of banana pulp using eggshells in both calcined and un-calcined forms to examine the extent of hydrolysis was conducted. Reactor CO containing banana pulp and inoculum but with no eggshells added was used as the control, while reactors C 1 , C 2 , C 3 , C 4 , and C 5 containing banana pulp and inoculum were spiked with 1, 3, 5, 7, and 9 g of un-calcined eggshells and calcined eggshells, for experiment 1 and 2, respectively. Anaerobic digestion was carried out at mesophilic temperature (35°C) for a period of 20 days. Digester C 3 with 5 g of calcined eggshells gave the largest cumulative biogas yield of 2343 mL with 62% CH 4 , follow. The least biogas yield of 10 mL was obtained in digester C 5 with 9 g of calcined eggshells additive. Key words : Anaerobic digestion, banana pulp hydrolysis biogas, eggshells.
