Antimicrobial Properties of Lyophilized Extracts of Olive Fruit, Pomegranate and Orange Peel Extracts against Foodborne Pathogenic and Spoilage Bacteria and Fungi In Vitro and in Food Matrices

Several novel antimicrobials with different concentrations of olive, pomegranate, and orange fruit pulp extracts were produced from agricultural byproducts and, after lyophilization, their antimicrobial activity and potential synergistic effects were evaluated in vitro and in food samples against foodborne pathogenic and spoilage bacteria and fungi. The Minimum Inhibitory of the tested bacteria was 7.5% or 10%, while fungi were inhibited at a concentration of 10% or above. The optical density of bacterial and yeast cultures was reduced to a different extent with all tested antimicrobial powders, compared to a control without antimicrobials, and mycelium growth of fungi was also restricted with extracts containing at least 90% olive extract. In food samples with inoculated pathogens and spoilage bacteria and fungi, the 100% olive extract was most inhibitory against E. coli, S. typhimurium, and L. monocytogenes in fresh burger and cheese spread samples (by 0.6 to 1.8 log cfu/g), except that S. typhimurium was better inhibited by a 90% olive and 10% pomegranate extract in burgers. The latter extract was also the most effective in controlling the growth of inoculated fungi (Aspergillus niger, Penicillium italicum, Rhodotorula mucilaginosa) in both yogurt and tomato juice samples, where it reduced fungal growth by 1–2.2 log cfu/g at the end of storage period. The results demonstrate that these novel encapsulated extracts could serve as natural antimicrobials of wide spectrum, in order to replace synthetic preservatives in foods and cosmetics.

Continuous-wave lasing has been obtained at 2. 714μm in a fluorozirconate single-mode fibre when pumping at 476.5, 501.7 or 647.1 nm. A threshold pump power of 7mW, an output laser power of 250μW and a linewidth less than 2 nm were measured
Wave passage effects on the seismic response of a maglev vehicle moving on multi-span guideway

As a seismic wave travels along the separate supports of an extended structure, the structure is subjected to multiple-support excitation due to seismic wave propagation. Considering the seismic wave passage effect, this paper describes seismic analysis of a maglev vehicle moving on a multiply supported gudieway. The guideway system is modeled as a series of simple beams and the vehicle as a four degrees-of-freedom (DOFs) rigid bar equipped with multiple onboard PI+LQR hybrid controllers. The controller is used to regulate control voltage for tuning both magnetic forces of uplift levitation and lateral guidance in the maglev system. Numerical studies show that as a maglev vehicle is equipped with more supported magnets then they can provide more control gains for tuning the guidance forces of the moving vehicle, and mitigate seismic-induced lateral vibration of a maglev vehicle running a guideway.
Sweden’s Thirty-year Experience with Tractor Rollovers

The purpose of this study was to analyze Sweden's experience of farm tractor rollover injuries over three decades during which policy requirements for safety features on tractors were first introduced and then later strengthened. The incidence of fatal and nonfatal tractor rollover injuries was compared with the proportion of farm tractors with and without rollover protective structures (ROPS) at different times from the late 1950s up to 1990. From the period 1957-1964 to the period 1986-1990 rollover fatalities decreased from 12 to 0.2 per 100,000 farm tractors. During that same period, the total number of Swedish farm tractors rose by 275% and the proportion of those tractors equipped with ROPS increased from 6% to 93%. The Swedish approach for prevention of fatal and nonfatal tractor rollover injuries was successful, emphasizing the value of public policy requiring ROPS on farm tractors.
Variational Analysis of Ridged Waveguide Modes

Brief expressions of eigenvalue problems, nornral modes, and electric-field profiles for all odd TE and TM modes of ridged waveguides, and the guide wavelength and characteristic impedance for the TE/sub 10/ dominant mode, are presented in this paper. In this analysis, the computation time can be reduced by getting simple approximated variational expressions for eigenvalue equations by using a trial function which satisfies the right-angled edge condition of a ridge. These theoretical results are in good agreement with the experimental results and the several references employed.
Nasotracheal intubation for dental surgery: A comparison of direct laryngoscopy with McGrath MAC videolaryngoscopy

Aim: The purpose of our study was to compare the McGrath MAC videolaryngoscope (VL) with the Macintosh direct laryngoscope (DL) for the efficacy during nasotracheal intubation (NTI) in patients undergoing dental surgery. Material and Methods: In total, 70 American Society of Anesthesiologist physical status (ASA) I-II patients who underwent elective dental surgery requiring NTI were included in this study. The patients were divided to two groups based on intubation using McGrath MAC VL (n=35) and Macintosh DL (n=35). The patients were monitored via electrocardiography (ECG), noninvasive arterial pressure, and peripheral oxygen saturation (SpO2) after they were taken to the operating room. Preoxygenation was performed with face mask for at least 3 minutes with 100 % O2. In addition, 2 mg/kg propofol and 1 μg/kg fentanyl were administered for anesthesia induction, and 0,6 mg/kg rocuronium was administered for muscular relaxation. NTI was performed 3 minutes after rocuronium injection with a nasotracheal tube. Anesthesia was maintained with sevoflurane and 50% air in oxygen. Mean arterial pressure (MAP), heart rate (HR), SpO2 and end tidal-carbon dioxide (EtCO2) were recorded at baseline; after anesthesia induction; and 1st, 2nd, 3th and 5th minutes after intubation. Cormack-Lehane and Mallampati Scores (MPS), laryngeal compression, duration of intubation, using Magill forceps, ease of intubation, and the incidence of complications due to intubation were recorded. Results: The demographic characteristics of the groups were similar. Regarding the success of the intubation, no significant difference was detected between the McGrath MAC VL group and the Macintosh DL group (p >0,05). However, when intubation times were compared, a significant difference was noted between groups (p<0,05). The intubation time was reduced in the McGrath MAC VL group. No statistically significant difference was observed regarding MAP and HR values. Intubation using McGrath MAC VL was significantly easier than direct laryngoscopy (p<0,05). No difference in complications was observed (p>0,05). Conclusion: We compared the McGrath MAC VL with the Macintosh DL for NTI and found that intubation was applied in less time using McGrath MAC VL than Macintosh DL. Intubation was more easy with McGrath MAC VL than Macintosh DL. We believe that McGrath MAC VL can be preferred to DL for NTI.
Accessible targets, but not advisable ones: The role of 'accessibility' in student apartment burglary

Given the apparent importance of the environmental characteristic "accessibility" in criminological literature in helping to explain the occurrence of burglary, this paper examined the role of accessibility in reported burglaries of private apartment units in Tallahassee, Florida, which were predominantly occupied by students. The study examined 96 reported burglaries committed at 94 apartment units, within 51 complexes.
Principais cadeias produtivas para o desenvolvimento da agroenergia no Norte do Brasil: limitações e perspectivas

Pesquisas voltadas para a bioenergia foram intensificadas na tentativa de cumprir as metas definidas pelo Protocolo de Kyoto (1997). Os biocombustíveis representam um dos ramos da bioenergia e entre os elos da cadeia produtiva dos biocombustíveis, o elo agrícola se destaca por ser o principal componente da formulação do preço final do combustível, havendo assim a necessidade de se buscar matérias-primas que colaborem para a redução dos preços, além de possibilitar a descentralização da produção. A região Norte do Brasil, especificamente, detém uma ampla variedade de espécies, que se apresentam como opções viáveis para a redução da dependência de combustíveis fósseis. Desta forma, trabalhos voltados para o estudo das cadeias do biodiesel e do etanol, principalmente desses elos, são essenciais, a fim de verificar fatores limitantes, bem como suas potencialidades. Portanto, objetivou-se elaborar uma revisão bibliográfica sobre a cadeia produtiva do biodiesel e etanol, visando apontar os principais fatores limitantes, potenciais e perspectivas para o desenvolvimento da agroenergia na região Norte. Sendo possível concluir que as perspectivas são positivas para o desenvolvimento da agroenergia na região Norte, por meio das culturas descritas. No entanto, fatores contribuem para a limitação de gargalos que demandam desenvolvimento tecnológico, planejamento e incentivo governamental, a fim de expandir a cadeia produtiva de biocombustíveis na região Norte.
Effect of relatively strong light injection on the chirp-to-power ratio and the 3 dB bandwidth of directly modulated semiconductor lasers

This paper describes a theoretical study of the small-signal modulation behavior of an injection-locked semiconductor laser. Illustrative examples are given, shelling a comparison between the free-running laser and the same laser with light injection. The results show that a substantial reduction of the chirp-to-power ratio (CPR) can be obtained, depending on both the injection level and the frequency detuning between the master and slave lasers. The behavior of the intensity modulation responses is also investigated, with the modulation conditions chosen in the dynamically stable locking range. It appears that the injection-locked laser may present a larger resonance frequency or modulation bandwidth with respect to those of the same laser under free-running operation.
Acoustic Word Embedding Based on Multi-Head Attention Quadruplet Network

Acoustic word embedding (AWE) has become a mainstream method in low-resource Query-by-Example keywords search. This letter proposes an AWE based on a multi-head attention quadruplet network, which can learn the attention weight sequence for all time frames of bidirectional Long Short-Term Memory by a multi-head self-attentive mechanism to pay attention to the time position information. At the same time, we construct a differences order quadruplet loss to train the AWE model to adequately consider the relative and absolute distances between the positive and negative sample pairs. In addition, attention mechanism, differences order quadruplet loss, and word label information are combined to design an objective function so that the AWE vectors have a better feature expression in the embedded space. The experimental results show that the proposed method can improve the learning ability of the network and make the AWEs more identifiable. The above two points result in better performance in the word discrimination task.
Conditioned Medium of Human Amniotic Epithelial Cells Alleviates Experimental Allergic Conjunctivitis Mainly by IL-1ra and IL-10

Allergic conjunctivitis (AC) is the most prevalent form of mucosal allergy, and the conditioned medium (CM) from mesenchymal stem cells has been reported to attenuate some allergic diseases. However, the therapeutic effects of CM from different tissue stem cells (TSC-CM) on allergic diseases have not been tested. Here, we studied the effects of topical administration of different human TSC-CM on experimental AC (EAC) mice. Only human amniotic epithelial cell-CM (AECM) significantly attenuated allergic eye symptoms and reduced the infiltration of immune cells and the levels of local inflammatory factors in the conjunctiva compared to EAC mice. In addition, AECM treatment decreased immunoglobulin E (IgE) release, histamine production, and the hyperpermeability of conjunctival vessels. Protein chip assays revealed that the levels of anti-inflammatory factors, interleukin-1 receptor antagonist (IL-1ra) and IL-10, were higher in AECM compared to other TSC-CM. Furthermore, the anti-allergic effects of AECM on EAC mice were abrogated when neutralized with IL-1ra or IL-10 antibody, and the similar phenomenon was for the activation and function of B cells and mast cells. Together, the present study demonstrated that AECM alleviates EAC symptoms by multiple anti-allergic mechanisms mainly via IL-1ra and IL-10. Such topical AECM therapy may represent a novel and feasible strategy for treating AC.
Stability Analysis of Switched Positive Systems with Delays

This brief investigates the stability problem of discrete-time switched positive systems with delays, and establishes some necessary and sufﬁcient conditions for the existence of a switched copositive Lyapunov function(SCLF) for such systems. It turns out that the size of the delays does not affect the stability of these systems. In other words, system stability is completely determined by the system matrices.
Directed Regeneration of Osteochondral Tissue by Hierarchical Assembly of Spatially Organized Composite Spheroids

The use of engineered scaffolds or stem cells is investigated widely in the repair of injured musculoskeletal tissue. However, the combined regeneration of hierarchical osteochondral tissue remains a challenge due to delamination between cartilage and subchondral bone or difficulty in spatial control over differentiation of transplanted stem cells. Here, two types of composite spheroids are prepared using adipose‐derived stem cells (hADSCs) and nanofibers coated with either transforming growth factor‐β3 or bone morphogenetic growth factor‐2 for chondrogenesis or osteogenesis, respectively. Each type of spheroid is then cultured within a 3D‐printed microchamber in a spatially arranged manner to recapitulate the bilayer structure of osteochondral tissue. The presence of inductive factors regionally modulates in vitro chondrogenic or osteogenic differentiation of hADSCs within the biphasic construct without dedifferentiation. Furthermore, hADSCs from each spheroid proliferate and sprout and successfully connect the two layers mimicking the osteochondral interface without apertures. In vivo transplantation of the biphasic construct onto a femoral trochlear groove defect in rabbit knee joint results in 21.2 ± 2.8% subchondral bone volume/total volume and a cartilage score of 25.0 ± 3.7. The present approach can be an effective therapeutic platform to engineer complex tissue.
Clinical and Prognostic Implications of 1p/19q, IDH, BRAF, MGMT Promoter, and TERT Promoter Alterations, and Expression of Ki-67 and p53 in Human Gliomas

Background and Objective Genetic alterations, including IDH, BRAF, and TERT promoter mutations (IDH-mu, BRAF-mu, TERTp-mu, respectively), 1p/19q co-deletion (1p/19q-codel), and MGMT promoter methylation (MGMTp-M), are correlated with glioma tumor development. Therefore, these genetic alterations could serve as biomarkers for the diagnosis, prognosis, and classification of gliomas, combined with the immunohistochemical markers Ki-67 and p53. However, the correlation between these alterations and the expression of Ki-67 and p53 is poorly understood. Methods We analyzed the prevalence and prognosis of these five alterations, as well as Ki-67 and p53 expression, in 103 primary grade II–IV gliomas via fluorescence qPCR, Sanger sequencing, fluorescence in situ hybridization, and immunohistochemistry. Results In the 103 cases, MGMTp-M was the most common alteration (70.9%), followed by TERTp-mu (58.3%), IDH-mu (46.6%), 1p/19q-codel (34.0%), and BRAF-mu (5.8%). No cases showed quintuple-positive alterations, but 26 cases (25.2%) showed quadruple-positive alterations (IDH-mu/TERTp-mu/MGMTp-M/1p/19q-codel). The percentage of TERTp-mu and 1p/19q-codel cases decreased with p53 expression, and the percentage of IDH-mu and 1p/19q-codel cases decreased with Ki-67 expression. IDH-mu, MGMTp-M, and 1p/19q-codel were positive factors for survival rates in glioma patients, while TERTp-mu, p53, and Ki-67 positivity were negative factors. Old age, histological grade IV, IDH-mu, 1p/19q-codel, Ki-67+, and p53+/Ki-67+ were significantly correlated with overall survival (OS). However, only p53+/Ki-67+ was an independent prognostic factor for OS in the multivariate Cox-model analysis. Conclusion IDH-mu only and quadruple-positivity were associated with good OS in glioma patients, while TERTp-mu only, TERTp-mu/MGMTp-M and p53+/Ki-67+ were associated with poor prognosis. Combining these genomic alterations and Ki-67/p53 expression should have clinical value in gliomas.
AN EMPIRICAL STUDY ON INTER-ORGANIZATIONAL NETWORK STRUCTURES FOR AUTOMATED VEHICLES

: This study aimed to examine empirically whether rapid changes in the technological environment affect inter-organizational relationships. In the automotive industry, the advantage of cohesive and vertically integrated inter-organizational relationships has been pointed out conventionally. The development of automated driving in the automotive industry, which is the subject of this thesis, is eliciting significant changes in the traditional automotive products and industry structure – changes generally associated with the automotive product structure moving closer to IT products. And, sharply conflicting views are found in previous studies as to whether this traditional inter-organizational network will change. As a methodology, I aimed to clarify empirically what kind of network structure of inter-organizational relations firms is growing with changes in industrial structure by creating a database of actual firm behavior. The database was analyzed using the social network analysis method, and the characteristics of growing firms’ organizational network structure were extracted. The results from an analysis of a large number of databases indicated that the technological change from automated driving may have prompted a change in inter-organizational relations toward a horizontal division of labor in the automobile industry in which so-called platform leader companies would emerge.
Applications of real-time speed control in rail-bound public transportation systems

This study gives an overview on applications of speed optimisation as one control measure for intelligent traffic management in rail-bound public transportation systems. The concept of operational target points and target windows is introduced. Speed and dwell time control are used to reach these targets, thereby improve throughput through system-related bottlenecks and reduce energy consumption. Different rail-bound transportation systems are compared and requirements for the application of speed control are derived. Case studies for three different rail-bound passenger transportation systems are presented that demonstrate the potential effects of these control methods on energy consumption and timetable deviation. These control strategies can be implemented using driver advisory systems (DAS) or fully automatic train operation (ATO).
Validation of generic municipal solid waste material properties for seismic design of landfills

In recent years, notable progress has been made with respect to the understanding of the mechanics of Municipal Solid Waste (MSW) response, and hence, generic MSW properties for static and seismic design of MSW landfills have been recommended. However, it is not clear if seismic design of MSW landfills based upon these generic material properties is conservative, and if it is, to what degree. An attempt is made to evaluate how adequate (i.e., conservative) seismic design of solid waste landfills based upon published generic material properties is. The basis for evaluation is one of very few well documented landfill case histories (the OII Landfill Case History) and selected generic material parameter sets. The results indicate that the use of generic material parameter sets at this site results in either reasonable prediction or slight over- prediction of recorded ground motions. The results of the parametric studies documented in this paper provide further insight on how to approach seismic design of MSW landfills.
Phytochemical analysis and antimicrobial and antioxidant activities of Hen-riettea succosa (Aubl.) DC. leaves

Henriettea succosa is a tree species consumed in abundance by birds, however, there is no report on its phytochemical profile and biological activity. This study performed the phytochemical screening and the antimicrobial and antioxidant potential of H. succosa leaves. The hexane (Hex), ethyl acetate (AcOEt) and methanol (MeOH) extracts of the leaves were evaluated for chemical composition by Thin Layer Chromatography and spectrophotometric analysis; the antimicrobial activity was determined by the Minimum Inhibitory Concentration (MIC) and Minimum Microbicide Concentration (MMC); antioxidant activity was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging, determination of the reducing power and the phosphomolybdenum complex reduction assay. The photoprotor action of the extracts was also evaluated. The results showed a higher content of phenolic compounds (444.08 ± 0.020 mg EAG/g) and tannins (414.37 ± 0.16 mg EAG/g) in the MeOH extract, which was effective against Staphylococcus aureus and Serratia marcescens, with MIC of 1 mg/ ml and CMM of 2 mg/ml. The MIC and MMC of AcOEt for Micrococcus luteus was 1 mg/mL, this was also considered the minimum concentration necessary for the Hex extract to act on the S. aureus strain. The MeOH extract showed greater antioxidant activity by the DPPH (79.09%) and reducing power (327.2 ± 0.00 mg EAA/g) methods, while the AcOEt extract showed greater activity by the phosphomolybdenum method (40.5%). However, none of the extracts showed a photoprotective effect against UV radiation. In summary, this study revealed that the leaves of H. succosa have secondary metabolites with bactericidal potential, in addition to antioxidant action.
Codec-Simulation Network for Joint Optimization of Video Coding With Pre- and Post-Processing

In real video coding systems, there might be pre-processing before the encoding and post-processing after the decoding. Those pre- and post-processing should be jointly optimized considering the existing of distortions introduced by lossy coding in between. This paper proposes a differentiable network to simulate the non-differentiable traditional coding to make the joint optimization of pre- and post-processing possible. The proposed codec-simulation network can achieve up to 49.4dB simulation accuracy for HEVC codec in intra mode. When we use down-sampling and up-sampling as examples of pre- and post-processing of a video codec, the joint optimization of these two processing modules in a video coding system can result in 46.88% and 55.15% BD-rate reduction based on PSNR and SSIM compared with that without joint optimization.
A PIEZOELECTRIC HARVESTER WITH AN INTEGRATED FREQUENCY- TUNING MECHANISM

We report the development of a piezoelectric energy harvester, whose resonance frequency can be tuned electrically by applying mechanical preloads through piezoelectric actuators. The harvester is similar to a design presented in (1), where a cantilever beam is equipped with two lateral arms which deliver an axial preload to the tip of the beam in order to change its resonance frequency. In this work, the main beam and arms are cut out of one dual-layer piezoceramic plate. The polarization and the electrodes are designed in such a manner, that the main beam generates electrical power in a vibrating environment, while the arms can be used as piezoelectric actuators in order to tune the resonance frequency of the whole structure. This compact and simple design promises a low priced fabrication at large scale.
