Effect of Different Enzymes Deactivation Methods on the Quality of Seepweed Tea

In order to study the effects of different enzymes deactivation methods on the quality of seepweed tea, the enzymes deactivation methods such as pan firing, steaming, water bathing and microwave on the quality of seepweed were discussed. The results show that the temperature of the steaming increase faster, the heat is even, and cause the sensory evaluation score of this method is the highest. The four enzymes deactivation methods have a significant effect on the color difference. And the brightness of the sample with the water bathing method is the highest. Steaming have a higher response value to the sensor of the electronic nose, with the most significant effects on the R(1), R(6), and R(8) components. Different enzymes deactivation methods also have a significant effect on the salty taste of seepweed tea, however there is no significant difference with other flavors. The total flavonoids and total phenols of samples by the steaming is the highest, with the value is 19.7 mg/g and the total phenol was 8.819 mg/g respectively. The sample by steaming have a strong penetration and the time is short, which is beneficial to the retention and conversion of organic chemical composition. It can be seen from the experimental results that the tea obtained after the steaming of the seepweed had a higher quality. Keywords—seepweed; quality characteristics; color difference; flavor
Inner models as a basis for traffic behaviour

The theory of "inner models" is described as it relates to driving behaviour. A product of cognitive psychology, "inner models" are mental representations of information procured by the subject and upon which complex decisions are based. Four assumptions of the theory are listed and evidence supporting them described. Accidents involving both experienced and inexperienced drivers i.e. those with and those without well developed inner models, are investigated and discusssed. Type of accident is shown to be related to degree of experience. The use of the theory in the Finnish driver training system is described. A pilot test, in which some pupils receiving training which developed their "hierachy of internal models", showed that such pupils performed better than the control group.
Application of bioreactor technology in plant propagation and secondary metabolite production

The use of in vitro technology for commercial propagation of different plant species and the production of bioactive compounds from them has become profitable industry worldwide. In the past decades, the progress in plant tissue culture technology was directed towards the introduction of the liquid medium for cultivation under submerged conditions in different bioreactor types, and automation of the entire process. Some applications of modified bioreactor systems and their importance for the advancement of plant biotechnology in the fields of agriculture, medicine, and pharmacy are discussed in this review.
Effects of In-Use Driving Conditions and Vehicle/Engine Operating Parameters on

This study provides a direct evaluation of real-time, on-road vehicle and engine operating parameters, and investigates their relationship to rich open-loop (or “off-cycle") emissions for a 1991 Ford Taurus driven in morning and evening commute hours over a matrix of eight freeway and eight urban routes in California’s South Coast Air Basin. Frequency of rich open-loop operation for these routes during commute hours was 0.003 percent and 0.007 percent, respectively. The low frequency of rich open-loop operation on these routes was attributed to the low velocities and close vehicle proximity during “gridlock” conditions. Higher frequencies of open-loop operation were observed for “aggressive” driving experiments for the same routes (0.44 percent freeway and 1.1 percent urban). The maximum frequency of rich open-loop operation occurred during off-peak hours, merging, and on a steep grade. The available data show there can be large variances in the frequency of open-loop operation between manufacturers, and .
Carotid collar : a device for auscultory detection of carotid artery stenosis

The carotid collar is a hardware device designed to aid in detecting carotid artery stenosis, a disease that increases the risk of stroke. This device consists of three electronic stethoscopes that record heart and carotid artery sounds and an electrocardiograph. A software application, ccrec, was written to make the device easy to use by displaying real-time waveforms and storing the recorded signals in files for later analysis. The results of some preliminary tests of the device’s ability to make accurate recordings, including the performance of the software and a test of the frequency response of the stethoscope sensors, are presented. The results suggest that this inexpensive device has considerable promise for rapid screening for carotid artery stenosis. Thesis Supervisor: John Guttag Title: Professor
Strategic and Cultural Misalignment: Knowledge Sharing Barriers in Project Networks

This article draws on theories from knowledge and project management to develop an understanding of how knowledge sharing is encouraged and hindered in the context of a multifirm network assembled to execute an innovative shipbuilding project. The empirical data are based on a qualitative case study, collected from in-depth face-to-face interviews in China and Norway, with the key people from a ship owner, shipbuilder, and ship technology supplier. The research indicates three interesting findings: First, differences in organizational culture (not national culture) hamper knowledge sharing. Second, a strategic misalignment made knowledge sharing difficult. Third, protecting knowledge by patenting and secrecy barely influenced the knowledge sharing processes. Based on previous research and lessons learned from case study experience, we suggest a framework to analyze challenges and links in project networks.
The impact of public reforms on the productivity of the Spanish ports: a parametric distance function approach

This paper tries to analyse the evolution of total factor productivity and its decomposition between 1986 and 2005 in the Spanish port authorities using a parametric distance function approach. Panel data for different outputs and inputs for the last 20 years have been constructed. During this period, the Spanish port authorities suffered three important regulatory changes. The results show that technical progress and scale efficiency gains contributed to improve total factor productivity whereas pure technical efficiency affected negatively. The change in the model of port management from a service port model to a landlord port model, the adoption of certain technologies and the possible existence of overcapacity caused by an increasing port competition, could explain these results.

Realization of micromachined-electromechanical devices for wireless communication applications

As the communication technology evolves day by day, the demands for low cost, low power, multifunctional and higher-speed data communication circuits are increasing enormously. All these essential requirements enforce significant challenges on the current technology and illustrate the need for new designs and advanced architectures. The challenges of reconfigurability, spectrum efficiency, security, miniaturization and cost minimization can only be met by ensuring that the transceiver/receiver is comprised of low-energy, low-cost, adaptive and high performance RF devices. With the potential to enable wide operational bandwidths, eliminate off-chip passive components, make interconnect losses negligible, and produce almost ideal switches and resonators in the context of a planar fabrication process compatible with existing IC processes, micromachining and Micro-Electro-Mechanical Systems (MEMS) has emerged to overcome the aforementioned problems of communication circuits. Up to date RF MEMS technology prove that on-chip switches with zero standby power consumption, low switching power and low actuation voltage; high quality inductors, capacitors and varactors; highly stable (quartz-like) oscillators and high performance filters operating in the tens of MHz to several GHz frequency range can be realized. The availability of such RF and microwave components will provide designers with the elements they have long hoped for to create novel and simple, but powerful, reconfigurable systems. In this thesis, realization of RF MEMS components such as capacitive switches, parallel plate variable capacitors, micromachined inductors and resonators for wireless communication applications are presented. The design and fabrication of each component are given in detail. The performance improvement of some blocks by integrating RF MEMS devices is demonstrated. Also the fabrication process problems limiting the performance parameters of RF MEMS components are addressed.
A comparison of traditional test blueprinting and item development to assessment engineering in a licensure context

With the need for larger and larger banks of items to support adaptive testing and to meet security concerns, large-scale item generation is a requirement for many certification and licensure programs. As part of the mass production of items, it is critical that the difficulty and the discrimination of the items be known without the need for pretesting. One approach to solving this need is item templating, an assessment engineering (AE) approach that is intended to control item difficulty and other psychometric operating characteristics for a class of items developed from each template. There are important advantages that can accrue to having exchangeable items that operate in a psychometrically similar manner in terms of item bank development (reduced time and lower cost to develop), pretesting efficiency, test security, and so forth. This study describes one method to use AE and item templates in a licensure context to yield sets of items with statistical characteristics that match the needs of the program with reduced need for pilot testing. It is shown that item variants developed in this method fit the Rasch calibration/scoring model as well, if not better than items developed in traditional ways and that the item variants from the same template yield similar classical and IRT statistics. One key result of the study is a method to use AE to evaluate the performance of item writers over time.
THE THREE-PARAMETER BLACK AND SCHOLES PROCESS

: In this paper, we propose a new study of the Black and Scholes Process (BSP). The main objective is to add a threshold parameter to the Black and Scholes Process. Using Kolmogorov equations, we obtain the probability density function and the moments of the process. Estimators of the parameters are studied by considering discrete sampling of the sample trajectories of the model and then using the maximum likelihood method and the Wicksell method.

Attempted Suicide in a Parkinsonian Patient Treated with DBS of the VIM and High Dose Carbidopa-Levodopa

Introduction Parkinson's disease (PD) is a complex disease that is often treated with dopaminergic medications such as carbidopa-levodopa and now with innovative interventions such as deep brain stimulation (DBS). While PD frequently presents with depression and apathy, research must elucidate whether its treatment modalities have an additive or synergistic effect that can lead to an increased suicide risk. DBS has been associated with depression, behavioral changes, and suicidality while dopaminergic treatment has also been shown to cause behavioral changes such as hypersexuality and impulsivity. Considering the now frequent practice of utilizing both DBS and carbidopa-levodopa to treat PD, it is crucial to understand how to properly manage PD patients who are displaying this overlap in symptomology. Case Report A 56-year-old Caucasian male with a 6-year diagnosis of PD who was being treated with high dose carbidopa-levodopa and left DBS of the ventral intermediate nucleus (VIM) presented after a suicide attempt. The patient was found to be severely depressed and had exhibited behavioral changes in the weeks leading up to the attempt. Imaging was performed to assess positional changes of DBS and carbidopa-levodopa dosage adjusted while under close observation in the inpatient unit. The patient was started on fluoxetine to treat the depressive symptoms and was eventually discharged with close monitoring. Discussion With PD and DBS being associated with behavioral changes and depressive symptoms and carbidopa-levodopa therapy being linked to behavioral changes such as impulsivity, it is important that these patients be closely monitored and research analyzes how these factors may interact and lead to an increased risk of suicide. Furthermore, when symptoms appear, a clear protocol must be established on managing these patients. We therefore recommend an approach that utilizes imaging to assess any changes in DBS placement, dose management of carbidopa-levodopa, and behavior monitoring in an inpatient setting.
Metal gates for advanced sub-80-nm SOI CMOS technology

Extensive simulations were performed to evaluate the impact of the gate workfunction on the sub-80-nm PD and FD SOI device performance. The optimal gate workfunction for the 50 nm technology node is 0.2 eV below (above) the conduction (valence) band edge of silicon for NMOS (PMOS). Midgap gates are not suitable for PD SOI CMOS due to the severe short-channel effects, but are desirable for FD SOI CMOS.

The ICT proficiencies of university teachers in Saudi Arabia: a case study to identify challenges and encouragements

Nowadays the use of information communications technology (ICT) is prevalent in higher education across all countries. This study focuses on the level of use of ICT among teachers at a leading university in Saudi Arabia. 16 indepth interviews reveal that the majority of teachers do not make use of ICT in their teaching. A number of attitudes were identified ranging from the idea that ICT would hinder the teaching process to an unwillingness to change long-standing teaching methods. However, the results also reveal that many teachers want to use more ICT in their teaching. Thus, there is preparedness to receive training programmes that focus on ICT. The results are encouraging as well as identifying specific challenges.
Spatial Heterogeneity and Factors Influencing Anemia and Severe Anemia among Under-5 Children in Ethiopia: Spatial and Multilevel Analysis

Background: Anemia is recognized as a significant public health problem in Ethiopia. Method: This secondary analysis, sampling technique and procedures done by DHS. A total of 8482 children aged 6–59 months were included in the study from EDHS 2016. Used tools for spatial heterogeneity analysis are Morans I, Local G*, Heat map, and Kulldorﬀ’s scan statistic, those carried out open source software (QGIS, GeoDa, SaTScan). Multilevel logistic regression analysis was used to identify both individual and household level factors associated with anemia and severe anemia, which measures between household variability using IHHC of the null model and generates 4 models PCV, AIC, and log-likelihood ratio used model selection for a report, which is carried out Stata 14.Result: The highest risk of both anemia and severe anemia regions are Somalia, Afar, DireDawa, and Harari. Specifically, all zones of Somalia, Afar (zone1, and 3), DireDawa, Harari, and Oromia higher risk of anemia and some of them are high risk for severe anemia. The high concentration of the disease showed in DireDawa, Harari, Jigjiga some part of Gambela and Benishangul Afar at the boundary of Amhara and Tigray and Eastern part of Tigray for anemia. Harari, DireDawa, and Afar at the border of Djibouti had high concentrated(density) severe anemia. Children (Younger age, lower preceding birth interval, stunted, underweight); mothers (younger age and anemic); households (poor and denser family number); and children from the highest and the lowest ecological zone are high risk for anemia. Additionally, children from the younger, work less, uneducated, poor, and anemic mother were high risk of a severe anemiaConclusion: Across the country, anemia is high, especially rift value areas highly affected by both anemia and severe anemia like Somalia regions and its neighbors. Those regions are not productive areas, lack of health facility, malaria region, backward for any access. So the concerned body must be tackled to minimize this childhood series problem. Before starting any intervention first must be prioritized according to risk, concentration, and characteristics.
Low‐Cost 2D Collimation of Real‐Time Pulsed Ultrasonic Beams by X‐Wave‐Based High‐Voltage Driving of Annular Arrays

Experimental limited-diffraction waves, based on proposals in the electromagnetic field for ideal infinite apertures (where the Bessel beam concept was already implicit), were reported for finite transverse apertures, firstly in the optic field and soon extended to an acoustic context, as the so-called X-waves. The first verification of the X-waves in acoustics was based on the sequential driving of the elements in an annular array and posterior synthesis of a limited-diffraction beam by using software composition of all the radiated patterns. This would need a complex and rather expensive multi-channel electronic instrumentation, to be extended for ultrasonic generation applicable in a strict real-time regime, as it is required for effective beam collimation in practical ultrasonic applications like non-invasive medical diagnosis by imaging or industrial inspection. In this chapter, principles and implementation details are shown for an author s proposal, by means of which an efficient and simple real-time generation of limiteddiffraction ultrasonic waves can be achieved in an impulsive regime. This is based on approaching X-wave non-diffracting solutions, by converting the complex morphology of the classical X-wave excitation signals in two-level simpler pulses (equivalent, -only for driving & vibration effects-). The pulses are optimized in amplitude & width using, as target functions, time-pulsed responses in emitting faces of all the array annuli. This approach would permit to attain efficient electronic X-beam collimation in Megahertz range, having both cost and size very reduced in the multi-channel hardware involved. A real-time ultrasonic emitting and beamforming configuration, based on the new proposal for the array electric excitations, is described in detail showing: the array elements characterization, HV driving pulses and related electronic procedure. Transient acoustic field results with good focusing pattern and large field depth are demonstrated. Our optimized results for the array excitations and the acoustic beam patterns, related to an ad-hoc designed 8-annuli array (with similar dimensions and working frequency as that proposed in the classical approach), are compared with those calculated using the exact 0-order X-wave solution. The comparison shows the viability of our proposal with only small deviations from the ideal case, which can be very acceptable for imaging.
