International Congress on Engineering and Food ( ICEF 11 ) An overview of encapsulation technologies for food applications

Encapsulation is a process to entrap active agents within a carrier material and it is a useful tool to improve delivery of bioactive molecules and living cells into foods. Materials used for design of protective shell of encapsulates must be food-grade, biodegradable and able to form a barrier between the internal phase and its surroundings. Among all materials, the most widely used for encapsulation in food applications are polysaccharides. Proteins and lipids are also appropriate for encapsulation. Spray drying is the most extensively applied encapsulation technique in the food industry because it is flexible, continuous, but more important an economical operation. Most of encapsulates are spray-dried ones, rest of them are prepared by spray-chilling, freeze-drying, melt extrusion and melt injection. Molecular inclusion in cyclodextrins and liposomal vesicles are more expensive technologies, and therefore, less exploited. There are number of reasons why to employ an encapsulation technology and this paper reviews some of them. For example, this technology may provide barriers between sensitive bioactive materials and the environment, and thus, to allow taste and aroma differentiation, mask bad tasting or smelling, stabilize food ingredients or increase their bioavailability. One of the most important reasons for encapsulation of active ingredients is to provide improved stability in final products and during processing. Another benefit of encapsulation is less evaporation and degradation of volatile actives, such as aroma. Furthermore, encapsulation is used to mask unpleasant feelings during eating, such as bitter taste and astringency of polyphenols. Also, another goal of employing encapsulation is to prevent reaction with other components in food products such as oxygen or water. In addition to the above, encapsulation may be used to immobilize cells or enzymes in food processing applications, such as fermentation process and metabolite production processes. There is an increasing demand to find suitable solutions that provide high productivity and, at the same time, satisfy an adequate quality of the final food products. This paper aims to provide a short overview of commonly used processes to encapsulate food actives. © 2011 Published by Elsevier Ltd.

Seminal plasma biochemistry and spermatozoa characteristics of Atlantic cod (Gadus morhua L.) of wild and cultivated origin.

Our objectives were to compare spermatozoa activity, morphology, and seminal plasma (SP) biochemistry between wild and cultivated Atlantic cod (Gadus morhua). Swimming velocities of wild cod spermatozoa were significantly faster than those of cultivated males. Wild males had a significantly larger spermatozoa head area, perimeter, and length, while cultivated males had more circular heads. Total monounsaturated fatty acids and the ratio of n-3/n-6 were significantly higher in sperm from wild males, while total n-6 from cultivated males was significantly higher than the wild males. Significantly higher concentrations of the fatty acids C14:0, C16:1n-7, C18:4n-3, C20:1n-11, C20:1n-9, C20:4n-3, C22:1n-11, and C22:6n-3 were observed in wild males, while significantly higher concentrations of C18:2n-6, C20:2n-6, and C22:5n-3 occurred in cultivated males. Osmolality, protein concentration, lactate dehydrogenase and superoxide dismutase activity of SP of wild males were significantly higher than the cultivated males. Antioxidant capacity of SP was significantly higher in cultivated males, while pH and anti-trypsin did not differ between fish origins. Four bands of anti-trypsin activity and nine protein bands were detected in SP. Performing a discriminant function analysis, on morphology and fatty acid data showed significant discrimination between wild and cultivated fish. Results are relevant to breeding programs and aquaculture development.
Effects of long-term biventricular stimulation for resynchronization on echocardiographic measures of remodeling.

BACKGROUND
Long-term ventricular resynchronization therapy improves symptom status. Changes in left ventricular remodeling have not been adequately evaluated.


METHODS AND RESULTS
Fifty-three patients with systolic heart failure and bundle-branch block underwent implantation of biventricular stimulation (BVS) devices as part of a randomized trial. Echocardiograms were acquired at randomization and at 6-week intervals until completion of 12 weeks of continuous BVS. There were no changes in heart rate or QRS duration after 12 weeks of BVS. Serum norepinephrine values did not change with BVS. After 12 weeks of BVS, left atrial volume decreased. Left ventricular end-systolic and end-diastolic dimensions and left ventricular end-systolic volume also decreased after 12 weeks of BVS. Sphericity index did not change. Measures of systolic function, including left ventricular outflow tract and aortic velocity time integral and myocardial performance index, improved.


CONCLUSIONS
Long-term resynchronization therapy results in atrial and ventricular reverse remodeling and improved hemodynamics.
Efficiency of parallel direct optimization.

Tremendous progress has been made at the level of sequential computation in phylogenetics. However, little attention has been paid to parallel computation. Parallel computing is particularly suited to phylogenetics because of the many ways large computational problems can be broken into parts that can be analyzed concurrently. In this paper, we investigate the scaling factors and efficiency of random addition and tree refinement strategies using the direct optimization software, POY, on a small (10 slave processors) and a large (256 slave processors) cluster of networked PCs running LINUX. These algorithms were tested on several data sets composed of DNA and morphology ranging from 40 to 500 taxa. Various algorithms in POY show fundamentally different properties within and between clusters. All algorithms are efficient on the small cluster for the 40-taxon data set. On the large cluster, multibuilding exhibits excellent parallel efficiency, whereas parallel building is inefficient. These results are independent of data set size. Branch swapping in parallel shows excellent speed-up for 16 slave processors on the large cluster. However, there is no appreciable speed-up for branch swapping with the further addition of slave processors (>16). This result is independent of data set size. Ratcheting in parallel is efficient with the addition of up to 32 processors in the large cluster. This result is independent of data set size.
In vitro and in vivo Efficacy of New Blue Light Emitting Diode Phototherapy Compared to Conventional Halogen Quartz Phototherapy for Neonatal Jaundice

High intensity light emitting diodes (LEDs) are being studied as possible light sources for the phototherapy of neonatal jaundice, as they can emit high intensity light of narrow wavelength band in the blue region of the visible light spectrum corresponding to the spectrum of maximal bilirubin absorption. We developed a prototype blue gallium nitride LED phototherapy unit with high intensity, and compared its efficacy to commercially used halogen quartz phototherapy device by measuring both in vitro and in vivo bilirubin photodegradation. The prototype device with two focused arrays, each with 500 blue LEDs, generated greater irradiance than the conventional device tested. The LED device showed a significantly higher efficacy of bilirubin photodegradation than the conventional phototherapy in both in vitro experiment using microhematocrit tubes (44+/-7% vs. 35+/-2%) and in vivo experiment using Gunn rats (30+/-9% vs. 16+/-8%). We conclude that high intensity blue LED device was much more effective than conventional phototherapy of both in vitro and in vivo bilirubin photodegradation. Further studies will be necessary to prove its clinical efficacy.
Radiofrequency ablation of advanced head and neck cancer.

OBJECTIVE
To determine if the application of radiofrequency ablation to advanced head and neck cancer (HNC) would result in local control of the tumor.


DESIGN
Radiofrequency ablation was applied to advanced head and neck malignant tumors in the participants of this nonrandomized controlled trial.


SETTING
Academic tertiary care medical center.


PARTICIPANTS
Twenty-one participants with recurrent and/or unresectable HNC who failed treatment with surgery, radiation, and/or chemotherapy were selected for the trial. Patients deemed appropriate for curative standard radiation or surgery were not accepted as participants.


INTERVENTION
Radiofrequency ablation was applied to head and neck tumors under general anesthesia and computed tomographic scan guidance.


MAIN OUTCOME MEASURES
The primary end point was local control. Computed tomographic scan tumor measurements were used to assess response by standard response evaluation criteria in solid tumors (RECIST) guidelines. Secondary outcome measures included survival and quality of life.


RESULTS
Eight of 13 participants had stable disease after intervention. Median survival was 127 days, and an improvement in University of Washington quality-of-life scores was noted. Adverse outcomes included 1 death due to carotid hemorrhage and 2 strokes.


CONCLUSION
Radiofrequency ablation is a palliative treatment alternative that shows promise in addressing the challenges of local control and quality of life in patients with incurable HNC who have failed standard curative treatment.
Favorable and Unfavorable Characteristics of EFL Teachers Perceived by University Students of Thailand

Teachers play pivotal roles in EFL classrooms. Characteristics of EFL teachers may affect students’ attitudes and motivations to language learning. The effective/good characteristics of the EFL teachers perceived by the students have been extensively investigated by the previous research works. However, the perceptions of the students from different backgrounds to EFL teachers may vary in different learning settings. In addition, the research works on both favorable and unfavorable characteristics of EFL teachers are comparatively scarce. This study aimed to investigate the favorable and unfavorable characteristics of the EFL teachers perceived by Thai university students. The data were collected from 6o students at Vongchavalitkul University. Open-ended questionnaires and semi-structured interviews were used as the main instruments for data collection. Useful information about EFL teachers’ personal trait-related characteristics and classroom teaching-related characteristics emerged from the data. The information is very useful and beneficial for the EFL teachers to reflect their personal characteristics and reconsider their classroom teaching, which may be very helpful for them to do some adjustment and preparation in their teaching to achieve better education results.
Building contingency planning for closed-loop supply chains with product recovery

Contingency planning is the first stage in developing a formal set of production planning and control activities for the reuse of products obtained via return flows in a closed-loop supply chain. The paper takes a contingency approach to explore the factors that impact production planning and control for closed-loop supply chains that incorporate product recovery. A series of three cases are presented, and a framework developed that shows the common activities required for all remanufacturing operations. To build on the similarities and illustrate and integrate the differences in closed-loop supply chains, Hayes and Wheelwright’s product–process matrix is used as a foundation to examine the three cases representing Remanufacture-to-Stock (RMTS), Reassemble-to-Order (RATO), and Remanufacture-to-Order (RMTO). These three cases offer end-points and an intermediate point for closed-loop supply operations. Since they represent different positions on the matrix, characteristics such as returns volume, timing, quality, product complexity, test and evaluation complexity, and remanufacturing complexity are explored. With a contingency theory for closed-loop supply chains that incorporate product recovery in place, past cases can now be reexamined and the potential for generalizability of the approach to similar types of other problems and applications can be assessed and determined. © 2002 Elsevier Science B.V.

Overtime evaluation of the vascular HEALing process after everolimus-eluting stent implantation by optical coherence tomography. The HEAL-EES study.

PURPOSE
Second-generation drug-eluting stent (DES) have shown a better safety and efficacy as compared to first generation DES due to an improved vascular healing process. This process has not been so far evaluated in vivo in an overtime fashion by optical coherent tomography (OCT). We sought to evaluate the vascular healing process after everolimus-eluting stent (EES) implantation at 6, 9 and 12months, by OCT.


METHODS
Consecutive 36 patients undergoing percutaneous coronary intervention with EES were randomized 1:1:1 to receive OCT imaging at 6 (group A), 9 (group B) or 12-month follow-up (group C). One patient from group C was excluded because of target lesion revascularization at 1-month, whereas 5 patients withdraw the informed consent. Finally, 30 patients were analyzed.


RESULTS
Neointimal thickness was not different between 3 groups (group A: 99.50 [94.06-127.79] μm, group B: 107.26 [83.48-133.59] μm, group C: 127.67 [102.51-138.49] μm; p=0.736). Although the percentage of "uncovered struts" was significantly higher in group A as compared to the other groups (8.0% vs. 4.4% vs. 2.9%, respectively; p=0.180), the ratio of uncovered to total struts per section <30% was similar between 3 groups (0.3% vs. 0.3% vs. 0%, respectively; p=1.000).


CONCLUSION
Healing process following EES implantation seems almost completed at 6-month follow-up. These data, which need to be confirmed in a larger study, may support the decision to shorten dual antiplatelet therapy.
Dynamics of Rhinoplasty

Nasal dynamics were studied on 87 patients undergoing rhinoplasty of one zone or two distant nasal zones. Statistical analysis of the result revealed that reduction of the nasion area, besides setting the soft tissue back, gave the appearance of increased intercanthal distance and lengthened the nose. Reduction of the nasal bridge resulted in a wider appearance on front view and a cephalically rotated tip on profile. Augmentation of the bridge affected the nose reversely. Tip cephalad rotation was achieved by resecting one of the three areas: the cephalad portion of the lower lateral cartilages (affecting the rims more), the caudal septum (affecting the central portion more), and the caudal portion of the medial crura of the lower lateral cartilages (affecting the central portion only). Resection of the alar base not only narrowed the nostrils but also moved the alar rim caudally. Furthermore, it reduced tip projection when a large alar base reduction was done. Reduction of the nasal spine increased the upper lip length on profile and reduced tip projection when a large reduction took place. Significant reduction in caudal nose projection resulted in widening of the alar base.
Appropriate Use Criteria for Coronary Revascularization and Trends in Utilization, Patient Selection, and Appropriateness of Percutaneous Coronary Intervention.

IMPORTANCE
Appropriate Use Criteria for Coronary Revascularization were developed to critically evaluate and improve patient selection for percutaneous coronary intervention (PCI). National trends in the appropriateness of PCI have not been examined.


OBJECTIVE
To examine trends in PCI utilization, patient selection, and procedural appropriateness following the introduction of Appropriate Use Criteria.


DESIGN, SETTING, AND PARTICIPANTS
Multicenter, longitudinal, cross-sectional analysis of patients undergoing PCI between July 1, 2009, and December 31, 2014, at hospitals continuously participating in the National Cardiovascular Data Registry CathPCI registry over the study period.


MAIN OUTCOMES AND MEASURES
Proportion of nonacute PCIs classified as inappropriate at the patient and hospital level using the 2012 Appropriate Use Criteria for Coronary Revascularization.


RESULTS
A total of 2.7 million PCI procedures from 766 hospitals were included. Annual PCI volume of acute indications was consistent over the study period (377,540 in 2010; 374,543 in 2014), but the volume of nonacute PCIs decreased from 89,704 in 2010 to 59,375 in 2014. Among patients undergoing nonacute PCI, there were significant increases in angina severity (Canadian Cardiovascular Society grade III/IV angina, 15.8% in 2010 and 38.4% in 2014), use of antianginal medications prior to PCI (at least 2 antianginal medications, 22.3% in 2010 and 35.1% in 2014), and high-risk findings on noninvasive testing (22.2% in 2010 and 33.2% in 2014) (P < .001 for all), but only modest increases in multivessel coronary artery disease (43.7% in 2010 and 47.5% in 2014, P < .001). The proportion of nonacute PCIs classified as inappropriate decreased from 26.2% (95% CI, 25.8%-26.6%) to 13.3% (95% CI, 13.1%-13.6%), and the absolute number of inappropriate PCIs decreased from 21,781 to 7921. Hospital-level variation in the proportion of PCIs classified as inappropriate persisted over the study period (median, 12.6% [interquartile range, 5.9%-22.9%] in 2014).


CONCLUSIONS AND RELEVANCE
Since the publication of the Appropriate Use Criteria for Coronary Revascularization in 2009, there have been significant reductions in the volume of nonacute PCI. The proportion of nonacute PCIs classified as inappropriate has declined, although hospital-level variation in inappropriate PCI persists.
UNPU: A 50.6TOPS/W unified deep neural network accelerator with 1b-to-16b fully-variable weight bit-precision

Deep neural network (DNN) accelerators [1-3] have been proposed to accelerate deep learning algorithms from face recognition to emotion recognition in mobile or embedded environments [3]. However, most works accelerate only the convolutional layers (CLs) or fully-connected layers (FCLs), and different DNNs, such as those containing recurrent layers (RLs) (useful for emotion recognition) have not been supported in hardware. A combined CNN-RNN accelerator [1], separately optimizing the computation-dominant CLs, and memory-dominant RLs or FCLs, was reported to increase overall performance, however, the number of processing elements (PEs) for CLs and RLs was limited by their area and consequently, performance was suboptimal in scenarios requiring only CLs or only RLs. Although the PEs for RLs can be reconfigured into PEs for CLs or vice versa, only a partial reconfiguration was possible resulting in marginal performance improvement. Moreover, previous works [1-2] supported a limited set of weight bit precisions, such as either 4b or 8b or 16b. However, lower weight bit-precisions can achieve better throughput and higher energy efficiency, and the optimal bit-precision can be varied according to different accuracy/performance requirements. Therefore, a unified DNN accelerator with fully-variable weight bit-precision is required for the energy-optimal operation of DNNs within a mobile environment.
DETECTION OF BOVINE HERPESVIRUS 1 FROM AN OUTBREAK OF INFECTIOUS BOVINE RHINOTRACHEITIS

Clinical symptoms from the respiratory tract were observed in cattle after the introduction of pregnant heifers into the dairy herd. Sera and nasal swabs from all animals and tissue samples from two dead animals were tested for BHV1. Specific antibodies against BHV1 were found in serum samples of 24 animals. Only one sample reacted doubtfully in gB ELISA. The virus was isolated only from nasal swabs and lungs collected from 2 weeks old calf. The remaining samples were negative in virus isolation test. PCR with external primers detected the presence of BHV1 in 11 nasal swabs and in lung and liver samples of 2 weeks old calf. In nested PCR almost all tested samples were positive. Restriction enzyme analysis confirmed the specificity of amplification. Results of laboratory diagnosis revealed that introduction of newly purchased animals into the herd initiated the outbreak of disease caused by BHV1.
Modelling and multicriteria analysis of water saving scenarios for an irrigation district in the upper Yellow River Basin

Water saving in irrigation is a main issue in the Yellow River basin. This paper refers to a field and modelling study performed in the Huinong Irrigation District, a very large surface irrigation system in Ningxia, upper Yellow River basin, intended to assess water saving and improved water use issues. The decision support system SEDAM was purposefully developed to evaluate alternative scenarios of improvements of farm and off-farm irrigation canal systems. It includes a demand and delivery simulation tool and adopts multicriteria analysis. Simulation is performed at various scales, starting at the distributor and then successively at the sub-branch, branch and sector scales. It uses a database built from random generation of system characteristics at these scales, and based on field surveys. Demand is built from exploring interactively the irrigation scheduling simulation model ISAREG and the surface irrigation models SRFR and SIRMOD, which were previously parameterized. The first is used to generate improved irrigation schedules and the second to define improved basin irrigation scenarios. In addition, a simple paddy irrigation tool is used to simulate replacing the current deep flooding method by shallow water irrigation. Water delivery scenarios are built to match those of demand including several improved procedures that aim at controlling runoff and seepage. Results indicate that progressively adopting farm and delivery system improvements leads to reduced canal seepage and runoff, which is essential to an effective functioning of the drainage system, in addition to control diversions into the Huinong canal. Water savings amount to more than 50% of actual water use. However, results referring to the economic criteria, particularly to the farm gross margin, reveal that more stringent improvements have low impacts, i.e. the respective utilities increase little when scenarios require higher investments. The described application shows that adopting a DSS simulation model and multicriteria analysis is appropriate to assess water use improvements in large irrigation systems and that it is advantageous to perform the analysis of related impacts by combining economic and environmental criteria. The importance of adopting improved delivery systems is also evidenced. # 2007 Elsevier B.V. All rights reserved. * Corresponding author. Tel.: +351 213653480; fax: +351 213621575.
