The Antioxidant Activity , Vitamin C Contents , Physical , Chemical and Sensory Properties of Ice Cream Supplemented with Cornelian Cherry ( Cornus mas L . ) Paste

The aim of this research was to investigate the effect of cornelian cherry (Cornus mas L.) paste (CP) on the quality properties of ice cream. CP was added to an ice cream mix at four concentrations (0, 5, 10 and 15%, w/w) for ice cream production. The increment of CP level caused the increased of vitamin C content, a values and overrun values, whereas it decreased the viscosity of samples compared to Control ice cream sample. The results indicated that lyophilised water extracts of CP (LWECP) contain remarkable phenolic compounds. The findings showed that there is a positive correlation between the total phenolics and flavonoid contents in LWECP and ice cream samples antioxidant activity. CP has shown to be an effective source of natural antioxidants. CP may be used as a source of natural colour and flavour agent in ice cream manufacture. CP enhanced vitamin C amounts of ice cream, and improve sensory properties. In the literature surveys of Science Direct, Web of Science, Google Scholar and Scopus databases an ice cream study using cornelian cherry fruit was not found.
Awareness and usage of government incentives in the tourism industry: a case study of guest houses in the Eden District Municipality, Western Cape Province, South Africa.

The significant contribution of small, medium and micro enterprises (SMMEs) to local economic development in the locality of municipalities has been recognized and therefore the prioritization of small business support and development by local government has become a focal point of municipal Local Economic Development (LED) programs. The tourism industry has proved to be a good tool for job creation within South Africa. However, many of the opportunities in this sector are not being exploited in a way that includes communities in the tourism value and supply chain. Developing SMMEs that can supply goods and services to the industry will significantly enhance job creation opportunities, especially in rural areas. However these SMMEs are often subject to a myriad of challenges compared to larger established businesses that fall outside the classifications of SMMEs. These challenges thus make it impossible for SMMEs to compete with established businesses and to actively participate in the first economy. The main aim of this article is to determine the awareness and usage of government incentives in the tourism industry by guest houses in the EDM. All surveyed guest houses in this study fall within the definition of SMME according to the National Small Business Act, No. 102 of 1996.
Development of a Flow-Cytometric Screening Method for MMP-14 Inhibitory Antibody

Author(s): Fang, Kuili | Advisor(s): Ge, Xin | Abstract: Mounting evidence suggests that MMP-14 (Matrix Metalloproteinase-14) plays an important role in cancer proliferation, invasion and migration to other healthy tissues through its extracellular matrix degradation activity. Toward the discovery of MMP-14 inhibitors, antibodies are emerging as a very attractive approach, due to their high specificity, low side effects and excellent in vivo stability. However, most current antibody selection methods are essentially binding assays with little control on inhibition function. Here, we report the development of a functional high-throughput screening method, which is able to identify inhibitory clones from non-specific or non-inhibitory clones. This novel method is based on antibody yeast display and dual color fluorescence-activated cell sorting (FACS). More specifically, the catalytic domain of MMP-14 and its native inhibitor N-TIMP-2 (N-terminal-domain of Tissue inhibitor of metalloproteinases-2) were successfully cloned, expressed, purified and refolded to their active formats, then conjugated with fluorophores Alexa488 and Alexa647 respectively. Yeast cells displaying various antibody clones were subjected to incubate with Alexa488-MMP-14 and Alexa647-N-TIMP-2. Dual Color FACS scanning results clearly demonstrated that the inhibitory antibody cells (DX-2400, 1F8) exhibited high Alexa488 fluorescence signals and low Alexa647 fluorescence signals, while the specific but non-inhibitory antibody cells (3B1, 2A10) exhibited high signals on both Alexa488 and Alexa647, and non-specific antibody cells (1H11, 2D9, 2F9, 1B11, b12, M18) exhibited low signals on both fluorophores. This proof-of-concept study paves the way for utilizing this functional screening method to isolate inhibitory antibodies from affinity maturation and synthetic antibody libraries in future researches.

In vivo antibacterial activity of alkaline phosphatase isolates from Escherichia coli isolated from diarrhea patients against Pseudomonas aeruginosa

A hundred and fifty samples of stools were collected from patients suffering diarrhea. Hundred and thirty bacterial isolated (86.7%) were identified 84 (64.6%) belonged to Escherichia coli, 23(17.7%) to Klebsiella pneumoniae, 10 (7.7%) Enterobacter cloacae, 7 (5.4%) to Shigella dysenteriae, 4(3.1%) to Salmonella typhi and 2(1.5%) to Pseudomonas aeruginosa. The ability of E.coli isolates to produce alkaline phosphatase enzyme was tested on MM agar medium along with pNPP. ALP was extracted, the crude extract activity and specific activity was 1.86 unit/ml and 20.44 unit/mg protein respectively. The enzyme purified by precipitating with ammonium sulfate (50-75%) saturation then using ion-exchange chromatography in DEAE-Cellulose ionic exchange column and gel filtration chromatography by using sepharose-6B gel filtration column, to obtained pure ALP enzyme with specific activity 272.73unit/mg, with 13.34 fold purification and yield of enzyme 56.45%. The in vivo investigation for the effect of ALP enzyme on the infection with P. aeruginosa was done using BLBC mice. The results shows that ALP degreased the number of bacteria in liver, spleen and lung with significant differences (P<0.05). Also the results shows a significant differences (P<0.05) in elevated levels of cytokines (IL-6, IL-10 and IL-12) compering with control group.
Socioeconomic Factors Affecting Adoption of Sunflower Varieties in Sindh

This research study is based on primary data collection from sunflower growers to assess the socioeconomic factors that are affecting the adoption of sunflower varieties in Sindh. Data samples have been selected from two districts; Badin and Thatta, as these districts are considered main sunflower growing areas in Sindh. The results reveal that Sunflower growers are using Hybrid varieties i.e. 43 percent planted Hysun-33, 29 percent Hysun38 and 28 percent Hysun-37 varieties. The finding of research using multinomial logistic regression suggests that farm size and level of education significantly affected the adoption of sunflower varieties. These factors are statistically significant at p<0.05. The other variables such as tenancy status and source of income are not statistically significant in the adoption of sunflower varieties in Sindh.
Assessing the effectiveness of waste minimization methods in solid waste reduction at the source by manufacturing firms in Malaysia

Manufacturing industries in Malaysia play a fundamental role in economic growth and enhancing the population’s standard of living. However, a huge quantity of industrial wastes is generated daily, exacerbating landfill disposal issues. Waste minimization as the most sustainable approach of waste handling contributes to a significant reduction of waste. In Malaysia, practicing waste minimization by manufacturing firms is not very common. Thus, this study attempted to determine the most commonly practiced methods of minimization by manufacturing firms in Malaysia. Also, the effectiveness of each method in waste reduction was explored. Data were collected through survey and analyzed through the quantitative and qualitative approaches from 214 manufacturing firms that cover small, medium, and large sizes with a 67.5% response rate. The questionnaire was developed based on the review of literature and is validated by a panel of experts. Paired sample T-test was used to compare the solid waste generation one year before and one year after practicing methods. Spearman Rho Correlation and multiple linear regression analysis were used to explore the relationships of methods and their significant contribution in waste reduction. Findings revealed that waste generation was significantly different after practicing waste minimization methods (p<0.05). With respect to the methods correlation and effectiveness in waste reduction, all waste minimization methods have a significant and positive correlation with waste reduction (p<0.05). Methods include segregation of wastes, on-site reuse and recycle, improved housekeeping, and equipment modification – all of which were found to be effective in waste reduction for Malaysian manufacturing firms (p<0.05).
A New Linear Programming Approach for TDGCS Layout Problem

Currently, considering the layout effect, the linear programming method based on column generation is generally proposed to solve the large-scale TDGCS layout problem, but layout scheme which is obtained by this method is the need to get multiple layout, a large number of calculations and a lot of time. However, there must be a balance between the material utilization ratio and computing time in the actual production process. Therefore, in this paper, a new linear programming method, which is based on two aspects of the minimum and maximum of objective function about the layout problem, is proposed. Firstly, a preliminary layout is finished from the aspect of the minimum optimization, then, a precise layout based on the preliminary layout is achieved from the aspect of maximum optimization. Compared with the original algorithm, theoretically speaking, this method can significantly reduce the amount of calculation through the calculation process, guaranteeing the material utilization.
Security Warning Life Cycle: Challenges and Panacea

Security warning is a very important aspect in computer security. Security warning is a form of message conveyed to inform user on the risk of allowing an application to run on the computer system. Security warning plays an important role in notify, warn and advise user about the potential result of an action beforehand. However, security warnings are often being ignored due to various reasons such as poor design of security warnings and too many technical terms used in security warnings. This research highlights insights into the discovery of problems and difficulties encountered by the users, approaches in improving security warnings and future direction of the security warning improvement process. We proposed to utilise the hybrid approach of iterative design and mental model in the effort to enhance the current implementation of security warning. Iterative design is a cyclic design process where prototyping, testing and refining are done repeatedly. A mental model is a person’s psychological representation of how they perceive and understand something. It is expected that this paper would benefit the researchers to comprehend approches and challenges to improve security warnings.
IMECE 2011-64479 THERMODYNAMICS APPLIED TO GEOTHERMAL POWER PLANTS . CASE STUDY : UNIT 5 , CERRO PRIETO , BAJA CALIFORNIA MEXICO

Cerro Prieto Geothermal Power Plant has a capacity of 720 MW. The earliest 5 units are 23 years old, and unit 5 from Cerro Prieto Uno was restored in 2008. This paper presents a thermodynamic analysis on the effects that has the increase of non condensable gases content in geothermal steam. Results show that the cooling water temperature will rise due to the energy entering the system with the water flow of the new vacuum system that feeds the condenser. Normal operation would be l imited and there exists a risk of not sustaining the condenser’s pressure. The new vacuum system, should extract from the condenser a flow 4 times larger, requiring 27% more steam at a higher pressure, as well as 4.5 times the quantity of cooling water. At this condition, the water returning to the condenser is 4.3 times larger than the original at a higher temperature, increasing in 218% the associated energy. A thermal behavior model was obtained for the cooling tower. In the most likely scenario the cooling tower exit temperature will be higher than the required, and to maintain the equilibrium it will be necessary to lower the condenser thermal load by reducing the steam flow to the turbine and accordingly, the power delivered.

A new characterization of salt deposits Ş

Exploration by wells of a salt accumulation generally involves continuous mechanical sampling and chemical analyses of cores to determine their NaCI content. Thus is obtaining a continuous geochemical profile in salt, giving information about salt quality (particularly NaCI content). As continuous mechanical sampling and chemical analyses are very expensive, this study propose a new method to achieve continuous geochemical profiles in salt proceeding from relationship between gamma natural log and NacCI content. The study area is placed in vicinity of Gura Slanic, Targu Ocna salt deposit where eight exploration wells were drilled. In four of those wells mechanical continuous sampling was carried out, and in all of them usual borehole-geophysics (i.e. caliper, electrical standard log and natural gamma log and neutron-gamma log) was carried out. From our experiments the best correlation between NaCI content and log recordings in salt appears for natural gamma log. The way of calculating NaCI content using these logs is as follows: 1) Fix an origin point, and through this point draw a "basis line" so that further measurements refer to this line; 2) Measure values of curve minimum amplitude (Imin) and maximum amplitude (lmax) recorded in salt; 3) Calculate relative size of natural gamma radiation ΔJX, with relation: ΔJx = (Ix Imin)/(Imax Imin) where lx is the value of gamma radiation at given depth; 4)Use the value of ΔJX in graph from Figure 2, which shows relationship between ΔJX and NaCI content, to determine the corresponding value of NaCI content. Using of relative size of natural gamma radiation (dimensionless), allows us to avoid drawbacks due to using of different units for gamma log (impulses per minute or API units), radiation background and tool type. This way NaCI content can be established in wells where no continuous mechanical sampling was available. To verify method accuracy we compared NaCI contents from chemical analyses with those calculated by our method, for four wells in which both geochemical profile and natural gamma log were available. A very good correlation can be observed as residual analysis gives a mean residual error of 0.73% and a standard deviation of 1.23%. Use of this method allows us to draw up geochemical profiles in wells where these are missing. Using overall data we draw up maps for various horizons and sections with NaCI content izolines. Such a section is shown in figure 4. In order to calculate salt geological reserve a map with Salt Formation thickness was drawing up and correlated with maps and sections with NaCI content izolines. Summarizing, this study achieved a new method to estimate NaCI content using natural gamma log which facilitate calculation of geological reserve for a new salt accumulation placed eastward Gura Slanic, Targu Ocna salt deposit. Key-Words: salt deposit, geochemical profile, gamma log
Augmentation of an Institute's Kitchen: An Ambient Auditory Display of Electric Power Consumption

Efficient feedback on energy consumption is regarded as one step towards a more sustainable lifestyle. Sonification is very apt to convey such information continuously in an ambient and effective way. This paper presents a pilot system for sonifying the electric power consumption of an institute’s kitchen. The reverberation of the kitchen is changed depending on the actual consumption and its difference to a weekly baseline. If the actual consumption is low, it is mapped to a plausible kitchen reverberation. If it is high compared to the baseline, the reverberation becomes unnatural. Evaluating the system gave insights on perceptibility and acceptance of auditory augmentation in a semi-home context.
Turbulent drag in a rotating frame

What is the turbulent drag force experienced by an object moving in a rotating fluid? This open and fundamental question can be addressed by measuring the torque needed to drive an impeller at a constant angular velocity ${\it\omega}$ in a water tank mounted on a platform rotating at a rate ${\it\Omega}$ . We report a dramatic reduction in drag as ${\it\Omega}$ increases, down to values as low as 12 % of the non-rotating drag. At small Rossby number $Ro={\it\omega}/{\it\Omega}$ , the decrease in the drag coefficient $K$ follows the approximate scaling law $K\sim Ro$ , which is predicted in the framework of nonlinear inertial-wave interactions and weak-turbulence theory. However, stereoscopic particle image velocimetry measurements indicate that this drag reduction instead originates from a weakening of the turbulence intensity in line with the two-dimensionalization of the large-scale flow.
Figures of merit for high-performance transparent electrodes using dip-coated silver nanowire networks

Homogeneous, highly conductive, and transparent silver nanowire thin films were fabricated using a simple dip-coating technique and a subsequent annealing step. Silver nanowires with two different average lengths (11 µm and 19µm) were used in the sample preparation to analyze the dependence of the sheet resistance on the length of the one-dimensional nanostructures. The best sample had a sheet resistance of 10. 2Ω/D with optical transmittance of 89.9%. Two figures of merit, the electrical to optical conductivity ratio (σDC/σOP) and ϕTC, were obtained for all the samples in order to measure their performance as transparent conductive materials.
Flow Regimes and Thermal Patterns in a Subway Station

As underground railway systems can generate enough heat from their operations to raise station and vehicle temperatures substantially[1,2]. This may lead to passenger discomfort and complain in warm weather conditions if the underground railway environment is not cooled. This paper presents modifications that can be made on air conditioning systems in subway stations by discussing and analyzing air flow and thermal patterns in a typical one.As CFD is now a popular design tool for engineers from different disciplines for pursuing an optimum design due to the high cost, complexity, and limited information obtained from experimental methods[3-5]. The pre-processor Gambit is used to create the geometric model with parametric features. Commercially available simulation software “Fluent 6.3” is incorporated to solve conservation of mass, momentum and energy in the processing of air distribution, and to analyze turbulence affection combined heat transfer on air distribution. In this paper work, the so-called standard k-e turbulence model, one of the most widespread turbulence models for industrial applications, was utilized. Basic parameters included in this work are air temperature, air velocity, relative humidity and turbulence parameters are used for numerical prediction of indoor air distribution. The CFD model was validated by comparing the simulation results with measurements of air velocity, and in a plane perpendicular to the supply diffuser and another plane in the vicinity of the advertisement lamp box. Thermal comfort was used in this paper to judge the impact of any modification. The thermal comfort prediction through this work was based on the PMV (Predicted Mean Vote) model and the PPD (Percentage Predicted Dissatisfied) model, the PMV and PPD were estimated using Fanger’s model.
Effects of Ingested Multi-Walled Carbon Nanotubes in Poecilia reticulata: Localization and Physiological Responses

Multiwalled carbon nanotubes (MWCNTs) are among the nanomaterials earmarked for water purification, yet they have been reported to cause toxicity in fresh water species. This study was conducted to investigate the histopathological and physiological effects of MWCNTs in freshwater fish (Poecilia reticulata). Literature reports that physicochemical properties of MWCNTs could be linked to their toxicological effects, hence the MWCNTs used in this study were characterized prior to (for physical and chemical properties) and during testing (for chemical interactions). Fourier transmission infra-red spectroscopy (FT-IR) revealed additional functional groups in oxidized multiwalled carbon nanotubes (o-MWCNTs) that were absent in the pristine multiwalled carbon nanotubes (p-MWCNTs). Transmission electron microscopy (TEM) and energy dispersive X-ray (EDX) also revealed amorphous carbon and residual Fe catalyst only in p-MWCNTs. The fish were exposed for 96 h in suspensions of p-MWCNTs and o-MWCNTs prepared by sonicating in moderately hard reconstituted water to test toxicity. Zeta potential measurements revealed an impartation of a negative charge onto MWCNT surfaces by HA, whilst hydrodynamic size measurements revealed aggregation/ disaggregation occurring alternately over the 96-h exposure time. Apart from only fish hyperactivity, no mortality was observed for 96-h acute tests for up to 300 mg/L MWCNT concentration. Histopathology revealed that MWCNTs aggregates were deposited mainly in the gut where they caused inflammation, hemorrhaging and oedema which were characterized by fragmented fibrin. Cell lyses also occurred in o-MWCNT exposed fish as evidenced by nuclei clusters among o-MWCNT aggregates. Statistical analysis by 2-way ANOVA followed by Bonferroni posttests showed that significant (p<0.05) reactive oxygen species (ROS) was induced as indicated by depleted antioxidant capacity (TCA), superoxide dismutase (SOD), lipid peroxidase (MDA) and protein carbonyl (PC) content between 3.25 and 15.0 mg/L of MWCNTs. These effects were attributed to the MWCNTs’ physicochemical properties as predetermined by functionalization (acid oxidation). The obtained results indicate that indeed MWCNTs cause toxic effects in freshwater fish, and although depuration was evident, there is a risk of MWCNT trophic transfer to fish eaters.
