Abstract: Cow milk, is a product of the mammary gland and
soymilk is a beverage made from soybeans; it is the liquid that
remains after soybeans are soaked. In this research effort, we
compared nutritional parameters of this two kind milk such as total
fat, fiber, protein, minerals (Ca, Fe and P), fatty acids, carbohydrate,
lactose, water, total solids, ash, pH, acidity and calories content in
one cup (245 g). Results showed soymilk contains 4.67 grams of fat,
0.52 of fatty acids, 3.18 of fiber, 6.73 of protein, 4.43 of
carbohydrate, 0.00 of lactose, 228.51 of water, 10.40 of total solids
and 0.66 of ash, also 9.80 milligrams of Ca, 1.42 of Fe, and 120.05 of
P, 79 Kcal of calories, pH=6.74 and acidity was 0.24%. Cow milk
contains 8.15 grams of fat, 5.07 of fatty acids, 0.00 of fiber, 8.02 of
protein, 11.37 of carbohydrate, ´Çá4.27 of lactose, 214.69 of water,
12.90 of total solids, 1.75 of ash, 290.36 milligrams of Ca, 0.12 of
Fe, and 226.92 of P, 150 Kcal of calories, pH=6.90 and acidity was
0.21% . Soy milk is one of plant-based complete proteins and cow
milk is a rich source of nutrients as well. Cow milk is containing near
twice as much fat as and ten times more fatty acids do soymilk. Cow
milk contains greater amounts of mineral (except Fe) it contain more
than three hundred times the amount of Ca and nearly twice the
amount of P as does soymilk but soymilk contains more Fe (ten time
more) than does cow milk. Cow milk and soy milk contain nearly
identical amounts of protein and water and fiber is a big plus, dairy
has none. Although what we choose to drink is really a mater of
personal preference and our health objectives but looking at the
comparison, soy looks like healthier choices.
Abstract: The oleaginous yeasts Lipomyces starkey were grown
in the presence of dairy industry wastewaters (DIW). The yeasts were
able to degrade the organic components of DIW and to produce a
significant fraction of their biomass as triglycerides.
When using DIW from the Ricotta cheese production or residual
whey as growth medium, the L. starkey could be cultured without
dilution nor external organic supplement. On the contrary, the yeasts
could only partially degrade the DIW from the Mozzarella cheese
production, due to the accumulation of a metabolic product beyond
the threshold of toxicity. In this case, a dilution of the DIW was
required to obtain a more efficient degradation of the carbon
compounds and an higher yield in oleaginous biomass.
The fatty acid distribution of the microbial oils obtained showed a
prevalence of oleic acid, and is compatible with the production of a II
generation biodiesel offering a good resistance to oxidation as well as
an excellent cold-performance.
Abstract: Graph partitioning is a NP-hard problem with multiple
conflicting objectives. The graph partitioning should minimize the
inter-partition relationship while maximizing the intra-partition
relationship. Furthermore, the partition load should be evenly
distributed over the respective partitions. Therefore this is a multiobjective
optimization problem (MOO). One of the approaches to
MOO is Pareto optimization which has been used in this paper. The
proposed methods of this paper used to improve the performance are
injecting best solutions of previous runs into the first generation of
next runs and also storing the non-dominated set of previous
generations to combine with later generation's non-dominated set.
These improvements prevent the GA from getting stuck in the local
optima and increase the probability of finding more optimal
solutions. Finally, a simulation research is carried out to investigate
the effectiveness of the proposed algorithm. The simulation results
confirm the effectiveness of the proposed method.
Abstract: Experiments were carried out at the Faculty of Food
Technology of Latvia University of Agriculture (LLU). Soft cheese
Kleo produced in Latvia was packed in a biodegradable PLA without
barrierproperties and VC999 BioPack lidding film PLA, coated with
a barrier of pure silicon oxide (SiOx) and in combination with
modified atmosphere (MAP) the influence on the shelf life was
investigated and compared with some conventional (OPP, PE/PA,
PE/OPA and Multibarrier 60) polymer film impact. Modified
atmosphere consisted of carbon dioxide CO2 (E 290) 30% and
nitrogen N2 (E 941) 70%. The analyzable samples were stored at the
temperature of +4.0±0.5 °C up to 32 days- and analyzed before
packaging and in the 0, 5th, 11th, 15th, 18th, 22nd, 25th, 29th and 32nd
day of storage. The shelf life was extended along to 32 days, good
outside appearance and lactic acid aroma was observed.
Abstract: Customarily, the LMTD correction factor, FT, is used
to screen alternative designs for a heat exchanger. Designs with
unacceptably low FT values are discarded. In this paper, authors have
proposed a more fundamental criterion, based on feasibility of a
multipass exchanger as the only criteria, followed by economic
optimization. This criterion, coupled with asymptotic energy targets,
provide the complete optimization space in a heat exchanger network
(HEN), where cost-optimization of HEN can be performed with only
Heat Recovery Approach temperature (HRAT) and number-of-shells
as variables.
Abstract: The aim of the present study was to evaluate the
mucoadhesion and the release of nicotinamide gel formulations using
in vitro methods. An agar plate technique was used to investigate the
adhesiveness of the gels whereas a diffusion apparatus was employed
to determine the release of nicotinamide from the gels. In this
respect, 10% w/w nicotinamide gels containing bioadhesive
polymers: Carbopol 934P (0.5-2% w/w), hydroxypropylmethyl
cellulose (HPMC) (4-10% w/w), sodium carboxymethyl cellulose
(SCMC) (4-6% w/w) and methylcellulose 4000 (MC) (3-5% w/w)
were prepared. The gel formulations had pH values in the range of
7.14 - 8.17, which were considered appropriate to oral mucosa
application. In general, the rank order of pH values appeared to be
SCMC > MC4000 > HPMC > Carbopol 934P. Types and
concentrations of polymers used somewhat affected the
adhesiveness. It was found that anionic polymers (Carbopol 934 and
SCMC) adhered more firmly to the agar plate than the neutral
polymers (HPMC and MC 4000). The formulation containing 0.5%
Carbopol 934P (F1) showed the highest release rate. With the
exception of the formulation F1, the neutral polymers tended to give
higher relate rates than the anionic polymers. For oral tissue
treatment, the optimum has to be balanced between the residence
time (adhesiveness) of the formulations and the release rate of the
drug. The formulations containing the anionic polymers: Carbopol
934P or SCMC possessed suitable physical properties (appearance,
pH and viscosity). In addition, for anionic polymer formulations,
justifiable mucoadhesive properties and reasonable release rates of
nicotinamide were achieved. Accordingly, these gel formulations
may be applied for the treatment of oral mucosal lesions.
Abstract: As increasing importance of symbiosis and cooperation among mobile communication industries, the mobile ecosystem has been especially highlighted in academia and practice. The structure of mobile ecosystem is quite complex and the ecological role of actors is important to understand that structure. In this respect, this study aims to explore structure of mobile ecosystem in the case of Korea using inter-industry network analysis. Then, the ecological roles in mobile ecosystem are identified using centrality measures as a result of network analysis: degree of centrality, closeness, and betweenness. The result shows that the manufacturing and service industries are separate. Also, the ecological roles of some actors are identified based on the characteristics of ecological terms: keystone, niche, and dominator. Based on the result of this paper, we expect that the policy makers can formulate the future of mobile industry and healthier mobile ecosystem can be constructed.
Abstract: Trauma in early life is widely regarded as a cause for
adult mental health problems. This study explores the role of
secondary trauma on later functioning in a sample of 359 university
students enrolled in undergraduate psychology classes in the United
States. Participants were initially divided into four groups based on
1) having directly experienced trauma (assaultive violence), 2)
having directly experienced trauma and secondary traumatization
through the unanticipated death of a close friend or family member
or witnessing of an injury or shocking even), 3) having no
experience of direct trauma but having experienced indirect trauma
(secondary trauma), or 4) reporting no exposure. Participants
completed a battery of measures on concepts associated with
psychological functioning which included measures of
psychological well-being, problem solving, coping and resiliency.
Findings discuss differences in psychological functioning and
resilience based on participants who experienced secondary
traumatization and assaultive violence versus secondary
traumatization alone.
Abstract: Palm oil could be converted to cocoa butter equivalent by lipase-catalyzed interesterification. The objective of this research was to investigate the structure modification of palm oil to cocoa butter equivalent using Carica papaya lipase –catalyzed interesterification. The study showed that the compositions of cocoa butter equivalent were affected by acyl donor sources, substrate ratio, initial water of enzyme, reaction time, reaction temperature and the amount of enzyme. Among three acyl donors tested (methyl stearate, ethyl stearate and stearic acid), methyl stearate appeared to be the best acyl donor for incorporation to palm oil structure. The best reaction conditions for cocoa butter equivalent production were : substrate ratio (palm oil : methyl stearate, mol/mol) at 1 : 4, water activity of enzyme at 0.11, reaction time at 4 h, reaction temperature at 45 ° C and 18% by weight of the enzyme. The chemical and physical properties of cocoa butter equivalent were 9.75 ± 0.41% free fatty acid, 44.89 ± 0.84 iodine number, 193.19 ± 0.78 sponification value and melting point at 37-39 °C.
Abstract: The common practice of operating S-rotor is in an
open environment; however there are times when the rotor is
installed in a bounded environment and there might be changes in the
performance of the rotor. This paper presents the changes in the
performance of S-rotor when operated in bounded flows. The
investigation was conducted experimentally to compare the
performance of the rotors in bounded environment against open
environment. Three different rotors models were designed, fabricated
and subjected to experimental measurements. All of the three models
were having 600 mm height and 300 mm Diameter. They were tested
in three different flow environments; namely: partially bounded
environment, fully bounded environment and open environment.
Rotors were found to have better starting up capabilities when
operated in bounded environment. Apart from that, all rotors manage
to achieve higher Power and Torque Coefficients at a higher Tip
Speed Ratio as compared to the open environment.
Abstract: An ethical mandate of the social work profession in the
United States is that BSW and MSW graduates are sufficiently
prepared to both understand diverse cultural values and beliefs and
offer services that are culturally sensitive and relevant to clients. This
skill set is particularly important for social workers in the 21st Century,
given the increasing globalization of the U.S. and world. The purpose
of this paper is to outline a pedagogical model for teaching cultural
competency that resulted in a significant increase in cultural
competency for MSW graduates at Western Kentucky University
(WKU). More specifically, this model is predicated on five specific
culturally sensitive principles and activities that were found to be
highly effective in conveying culturally relevant knowledge and skills
to MSW students at WKU. Future studies can assess the effectiveness
of these principles in other MSW programs across the U.S. and abroad.
Abstract: The disaster from functional gastrointestinal disorders has detrimental impact on the quality of life of the effected population and imposes a tremendous social and economic burden. There are, however, rare diagnostic methods for the functional gastrointestinal disorders. Our research group identified recently that the gastrointestinal tract well in the patients with the functional gastrointestinal disorders becomes more rigid than healthy people when palpating the abdominal regions overlaying the gastrointestinal tract. Objective of current study is, therefore, identify feasibility of a diagnostic system for the functional gastrointestinal disorders based on ultrasound technique, which can quantify the characteristics above. Two-dimensional finite difference (FD) models (one normal and two rigid model) were developed to analyze the reflective characteristic (displacement) on each soft-tissue layer responded after application of ultrasound signals. The FD analysis was then based on elastic ultrasound theory. Validation of the model was performed via comparison of the characteristic of the ultrasonic responses predicted by FD analysis with that determined from the actual specimens for the normal and rigid conditions. Based on the results from FD analysis, ultrasound system for diagnosis of the functional gastrointestinal disorders was developed and clinically tested via application of it to 40 human subjects with/without functional gastrointestinal disorders who were assigned to Normal and Patient Groups. The FD models were favorably validated. The results from FD analysis showed that the maximum displacement amplitude in the rigid models (0.12 and 0.16) at the interface between the fat and muscle layers was explicitly less than that in the normal model (0.29). The results from actual specimens showed that the maximum amplitude of the ultrasonic reflective signal in the rigid models (0.2±0.1Vp-p) at the interface between the fat and muscle layers was explicitly higher than that in the normal model (0.1±0.2 Vp-p). Clinical tests using our customized ultrasound system showed that the maximum amplitudes of the ultrasonic reflective signals near to the gastrointestinal tract well for the patient group (2.6±0.3 Vp-p) were generally higher than those in normal group (0.1±0.2 Vp-p). Here, maximum reflective signals was appeared at 20mm depth approximately from abdominal skin for all human subjects, corresponding to the location of the boundary layer close to gastrointestinal tract well. These findings suggest that our customized ultrasound system using the ultrasonic reflective signal may be helpful to the diagnosis of the functional gastrointestinal disorders.
Abstract: This paper presents a novel approach to assessing textile porosity by the application of the image analysis techniques. The images of different types of sample fabrics, taken through a microscope when the fabric is placed over a constant light source,transfer the problem into the image analysis domain. Indeed, porosity can thus be expressed in terms of a brightness percentage index calculated on the digital microscope image. Furthermore, it is meaningful to compare the brightness percentage index with the air permeability and the tightness indices of each fabric type. We have experimentally shown that there exists an approximately linear relation between brightness percentage and air permeability indices.
Abstract: Routing in mobile ad hoc networks is a challenging task because nodes are free to move randomly. In DSR like all On- Demand routing algorithms, route discovery mechanism is associated with great delay. More Clearly in DSR routing protocol to send route reply packet, when current route breaks, destination seeks a new route. In this paper we try to change route selection mechanism proactively. We also define a link stability parameter in which a stability value is assigned to each link. Given this feature, destination node can estimate stability of routes and can select the best and more stable route. Therefore we can reduce the delay and jitter of sending data packets.
Abstract: In the package design industry, there are a lot of tacit knowledge resided within each designer. The objectives are to capture them and compile it to be used as a teaching resource and to create a video clip of package design process as well as to evaluate its quality and learning effectiveness. Interview were used as a technique for capturing knowledge in brand design concept, differentiation, recognition, rank of recognition factor, consumer survey, knowledge about marketing, research, graphic design, the effect of color, and law and regulation. Video clip about package design were created. The clip consisted of both the speech and clip of actual process. The quality of the video in term of media was ranked as good while the content was ranked as excellent. The students- score on post-test was significantly greater than that of pretest (p>0.001).
Abstract: Intelligent tutoring systems constitute an evolution of computer-aided educational software. We present here the modules of an intelligent tutoring system for Automatic Control, developed in our department. Through the software application developed,students can perform complete automatic control laboratory experiments, either over the departmental local area network or over the Internet. Monitoring of access to the system (local as well as international), along with student performance statistics, has yielded strongly encouraging results (as of fall 2004), despite the advanced technical content of the presented paradigm, thus showing the potential of the system developed for education and for training.
Abstract: This paper deals with the problem of non-uniform
torsion in thin-walled elastic beams with asymmetric cross-section,
removing the basic concept of a fixed center of twist, necessary in the
Vlasov-s and Benscoter-s theories to obtain a warping stress field
equivalent to zero. In this new torsion/flexure theory, despite of the
classical ones, the warping function will punctually satisfy the first
indefinite equilibrium equation along the beam axis and it wont- be
necessary to introduce the classical congruence condition, to take into
account the effect of the beam restraints. The solution, based on the
Fourier development of the displacement field, is obtained assuming
that the applied external torque is constant along the beam axis and
on both beam ends the unit twist angle and the warping axial
displacement functions are totally restrained.
Finally, in order to verify the feasibility of the proposed method
and to compare it with the classical theories, two applications are
carried out. The first one, relative to an open profile, is necessary to
test the numerical method adopted to find the solution; the second
one, instead, is relative to a simplified containership section,
considered as full restrained in correspondence of two adjacent
transverse bulkheads.
Abstract: Enterprises need a strategic plan to retain their skillful employees and provide their career management, sustain their existence, to have growth and leadership qualities, to reach the objectives to increase the value of the enterprise and to not to be affected from changing demographic structure. In the cases when the long term career expectations of skillful employees are in integrity with the enterprise’s interests, skill management process is directly related to the career management. With a long term plan, the enterprises should cover the labor force need that may arise in the future by using systematic career development programs and be prepared against developments for all times. Skill management is considered as a practice with which career mobility is planned for the skillful employee to be prepared for high level positions. Career planning is the planning of an employee’s progress or promotion within an organization for which he works by developing his knowledge, skills, abilities and motives. Career planning is considered as an individual’s planning his future and the position which he wants to have, the area which he want to work in, the objectives which he want to reach. With the aim of contributing the abovementioned discussion process, career management concept and its perception manner are examined in this study in a comparative manner.
Abstract: Developing a nation geared by the principle of
sustainable development has been one of the piers in moulding a
greater nation for Malaysia since its independence. This is seen by
the act of joining the United Nations in 1957, just a month after
gaining their independence. The United Nations is an international
organization that aims to unite the nations worldwide based on
justice, human dignity and human well-being. Malaysia has
established a local body called the United Nations Malaysia which
collaborates with the government to accomplish the aim of
supporting sustainable development in Malaysia. Agenda 21 is an
international document produced from the Earth Summit providing
guidelines of implementing sustainable development globally,
nationally and locally. Initiatives of applying Agenda 21 in Malaysia
have been taken by the government and non-profit organizations to
expose issues regarding sustainable development and providing
environmental education to the community to increase awareness
towards environmental protection.
Abstract: The lack of security obstructs a large scale de- ployment of the multicast communication model. There- fore, a host of research works have been achieved in order to deal with several issues relating to securing the multicast, such as confidentiality, authentication, non-repudiation, in- tegrity and access control. Many applications require au- thenticating the source of the received traffic, such as broadcasting stock quotes and videoconferencing and hence source authentication is a required component in the whole multicast security architecture. In this paper, we propose a new and efficient source au- thentication protocol which guarantees non-repudiation for multicast flows, and tolerates packet loss. We have simu- lated our protocol using NS-2, and the simulation results show that the protocol allows to achieve improvements over protocols fitting into the same category.
