Antimicrobial activities of microbial essential fatty acid against foodborne pathogenic bacteria

Background and Objectives: Human health and development have been related to dietary intake of essential fatty acids (omega 3, 6 and 9) and important for brain development, immune system function, and blood pressure regulation. Microbial essential oils are more natural and safer alternatives to synthetic preservatives. These oils have been demonstrated to have antibacterial activity within food systems and may be ideal additives to food formulations. Zygomycete fungi are well-known as good candidate for production of essential oils. Materials and Methods: Essential oils of fungi Mucor rouxii, Mucor circinelloides and Cuninghamella echinulata were extracted and fatty acids were analyzed by GC, for the first, antimicrobial activity of the fungi essential oils against foodborne pathogenic bacteria E. coli, S. aureus, B. cereus, B. subtilis, and S. enterica was examined by disc diffusion and well diffusion methods and the minimal inhibitory concentrations (MIC) of oils were determined by microtiter plate. Results: The fungi oils were exhibited the stron g antibacterial effect against Gram-positive bacteria, B. cereus, S. aureus and B. subtilis higher than Gram-negative and commercial oleic acid and linoleic acid. The MIC of the fungi oil extracts was 0.25 mg/ml for B. cereus and B. subtilis and 0.5 mg/ml about S. aureus. This research demonstrated microbial essential oils may be suitable for their antimicrobial properties in food. Conclusion: Microbial essential oil with good antibacterial activity could also be used in selected cases like foodborne disease.
SpiralSpy: Exploring a Stealthy and Practical Covert Channel to Attack Air-gapped Computing Devices via mmWave Sensing

—Covert channels are a method of communication that is used to exﬁltrate information from computing devices and break the security policy of computer systems. Any shared resource can be potentially leveraged as a covert channel, and conventional wisdom of cyber-security believes that air-gapped computing devices, disconnected from the Internet, are highly secured. Recent studies show that advanced covert channel attacks using acoustic, thermal, and electromagnetic effects can only work under a limited proximity constraint (e.g., within 2 meters). In this work, we present SpiralSpy , a new covert channel to attack air-gapped computing devices through millimeter-wave (mmWave) sensing technologies. SpiralSpy can be stealthily launched and circumvent strongly isolated computing devices from a practical distance (up to 8 meters). Speciﬁcally, we demonstrate that ordinal cooling fans can be leveraged for covert channel attacks. A malicious software inside air-gapped computing devices can saliently encode conﬁdential data into the fan control signals, and modulated status on fan motions can be remotely decoded by a commodity mmWave sensor. SpiralSpy can be adopted on multiple-fan systems and enable a scalable capacity for multi-channel and high-speed information transfer. We evaluate SpiralSpy with 71 computing devices with cooling fans. Experimental results demonstrate that SpiralSpy can achieve
Impacto de los efectos lineales y no lineales en el requerimiento del ancho de línea del transmisor en sistemas WDM-DPSK Impact of Linear and Nonlinear Effects in the Requirements of the Transmitter Linewidth for WDM-DPSK Systems

In this paper we analyze the impact in the requirements of the linewidth of the laser, due to the linear and non-linear effects introduced by the optical fiber, in a WDM-PON transmission system using DPSK modulation format. We measured the BER for different data bit rates, transmitted power and dispersion coefficient of the optical fiber. The study was performed using simulations in the computational tool OPTSIM�. We found that if the data bit rate is increased, it is possible to use optical sources with higher linewidth using DPSK modulation format, decreasing the cost of the transmitter. Additionally, we proved that the non-linear effects mostly affect the transmission systems where optical fibers with dispersion coefficients near zero are used.
Clinical Experience of Therapeutic Hypothermia in Cases of Near-Hanging and Recovered from Cardiac Arrest Due to Hanging

Objective There is no specific treatment for comatose patients after near-hanging or in those who recover from cardiac arrest (CA) caused by hanging. Since 2009, we have used therapeutic hypothermia (TH) to treat all comatose survivors of near-hanging and in patients who recovered from CA caused by hanging. The purpose of this study was to describe the outcomes in comatose patients after near-hanging. Design Case series. Setting Emergency departments of two regional hospitals. Methods We collected patient data from the Samsung Medical Center hypothermia database between November 2009 and November 2011. We included all patients presented with near-hanging or CA caused by hanging; who remained comatose and received TH after resuscitation for analysis. Clinical characteristics and outcome of patients were presented. Results During the study period, 26 patients were admitted to the emergency department after near-hanging or CA caused by hanging; 21 patients were enrolled in this study. Twelve patients with CA and 9 comatose patients without CA were treated with TH. Only 1 patient with CA had a good neurological outcome. By contrast, all near-hanging patients without CA had a good neurological outcome. Conclusions TH can be an effective therapeutic modality in cases of near-hanging without CA. However, the effectiveness of TH is questionable in patients who survive from CA caused by hanging. (Hong Kong j.emerg.med. 2014;21:316-321)
Effect of Endoscopic Management of Unresectable Malignant Biliary Strictures on Patient’s Quality of Life

Background: Biliary strictures(BS) possess challenging diagnosis, requiring a multidisciplinary approach. In gastrointestinal clinical practice, the occurrence of biliary strictures is quite common. Multiple diagnostic techniques are used to examine BS in which endoscopic management is considered comparatively effective and non-invasive intervention.

Hazard Integrated: Understanding Security Risks in App Extensions to Team Chat Systems

—Team Chat ( TACT ) systems are now widely used for online collaborations and project management. A unique feature of these systems is their integration of third-party apps, which extends their capabilities but also brings in the complexity that could potentially put the TACT system and its end-users at risk. In this paper, for the first time, we demonstrate that third-party apps in TACT systems indeed open the door to new security risks, such as privilege escalation, deception, and privacy leakage. We studied 12 popular TACT systems, following the key steps of a third-party app’s life cycle (its installation, update, configuration, and runtime operations). Notably, we designed and implemented a pipeline for efficiently identifying the security risks of TA APIs, a core feature provided for system-app communication. Our study leads to the discovery of 55 security issues across the 12 platforms, with 25 in the install and configuration stages and 30 vulnerable (or risky) APIs. These security weaknesses are mostly introduced by improper design, lack of fine-grained access control, and ambiguous data-access policies. We reported our findings to all related parties, and 8 have been acknowledged. Although we are still working with the TACT vendors to determine the security impacts of the remaining flaws, their significance has already been confirmed by our user study, which further reveals users’ concerns about some security policies implemented on mainstream TACT platforms and their misconceptions about the protection in place. Also, our communication with the vendors indicates that their threat models have not been well-thought-out, with some assumptions conflicting with each other. We
Proper location of the transducers for an active noise barrier

The main intention of this study is to propose general criteria for the locations of the control sources and error microphones that improve the performance of the active noise barrier. Based on the proposed criteria of this study, the greater reduction is attained when the diffracted field of the noise source is canceled with the diffracted field of the control sources, that is, it is suggested to locate the control sources on the incident side and below the path that connects the furthest point in the shadow zone to the edge of the barrier. Furthermore, it is suggested that the error microphones are most suitably placed on the shadow side of the barrier where they are under the diffracted field of both the primary and control sources. The results also show that with these general criteria, the active noise control achieves an extra reduction that varies from 14.9 to 3.9 dB (for the one-third octave bands from 63 Hz to 1 kHz) and 9.3 dB for the broadband noises.
Cross-Language Attacks

—Memory corruption attacks against unsafe programming languages like C/C++ have been a major threat to computer systems for multiple decades. Various sanitizers and runtime exploit mitigation techniques have been shown to only provide partial protection at best. Recently developed ‘safe’ programming languages such as Rust and Go hold the promise to change this paradigm by preventing memory corruption bugs using a strong type system and proper compile-time and runtime checks. Gradual deployment of these languages has been touted as a way of improving the security of existing applications before entire applications can be developed in safe languages. This is notable in popular applications such as Firefox and Tor. In this paper, we systematically analyze the security of multi-language applications. We show that because language safety checks in safe languages and exploit mitigation techniques applied to unsafe languages ( e.g., Control-Flow Integrity) break different stages of an exploit to prevent control hijacking attacks, an attacker can carefully maneuver between the languages to mount a successful attack. In essence, we illustrate that the incompatible set of assumptions made in various languages enables attacks that are not possible in each language alone. We study different variants of these attacks and analyze Firefox to illustrate the feasibility and extent of this problem. Our ﬁndings show that gradual deployment of safe programming languages, if not done with extreme care, can indeed be detrimental to security.
Nasotracheal Intubation After Transsphenoidal Surgery: A Case Report

Nasotracheal intubation is generally used in maxillofacial and oral surgeries under general anesthesia. However, nasal intubation may cause various complications including epistaxis, retropharyngeal dissection, and intracranial penetration of the nasotracheal tube, which occurs in patients with basal skull defects or fractures. Therefore, nasotracheal intubation is usually contraindicated in such patients. Herein, we describe an alternative technique using a balloon catheter in nasotracheal intubation to avoid surgical airway management in a patient with a history of transsphenoidal surgery. The use of a balloon catheter may be a simple and safe method of nasotracheal intubation in patients with basal skull defects.
Changes in the Complexity of Limb Movements during the First Year of Life across Different Tasks

Infants’ limb movements evolve from disorganized to more selectively coordinated during the first year of life as they learn to navigate and interact with an ever-changing environment more efficiently. However, how these coordination patterns change during the first year of life and across different contexts is unknown. Here, we used wearable motion trackers to study the developmental changes in the complexity of limb movements (arms and legs) at 4, 6, 9 and 12 months of age in two different tasks: rhythmic rattle-shaking and free play. We applied Multidimensional Recurrence Quantification Analysis (MdRQA) to capture the nonlinear changes in infants’ limb complexity. We show that the MdRQA parameters (entropy, recurrence rate and mean line) are task-dependent only at 9 and 12 months of age, with higher values in rattle-shaking than free play. Since rattle-shaking elicits more stable and repetitive limb movements than the free exploration of multiple objects, we interpret our data as reflecting an increase in infants’ motor control that allows for stable body positioning and easier execution of limb movements. Infants’ motor system becomes more stable and flexible with age, allowing for flexible adaptation of behaviors to task demands.
A broadband circular polarization patch antenna with differential-feeding

A broadband circular polarization patch antenna, differential-fed by a pair of folded plate, is proposed. The use of the two patches can broaden the bandwidth and the differential-feeding can provide a good symmetrical pattern. The impedance bandwidth (VSWR<2) of the proposed antenna is 38.5%. The axis ratio (AR) at the centre frequency of 2 GHz is 2.3 dB in measurement. Besides, the radiation pattern, both E-plane and H-plane, are symmetrical respectively.
Surface-Modified Adsorbent from Artocarpus heterophyllus Lam Biomass to Confine Reactive Red 194 in Real and Synthetic Effluents: Kinetics and Equilibrium Study

Chemical activation of Artocarpus heterophyllus Lam (jackfruit peel) via phosphoric acid was focused on this study for the preparation of activated carbon. Carbonization was done at a temperature of 400°C based on the nature of biomass after the impregnation ratio of 1 : 1 (weight of phosphoric acid/weight of raw material). Titanium dioxide was doped on the prepared activated carbon through the sol-gel method. Titanium dioxide doped activated carbon was synthesized to perceive the nature of adsorbents under ambient conditions. Both JPAC and JPAC/TiO2 adsorbents were characterized by the point of zero charges, Fourier transform of infrared spectroscopy, X-ray diffraction spectroscopy, Brunauer-Emmett-Teller analysis, and scanning electron microscopy with energy-dispersive X-ray analysis. The adsorption capacity of Reactive Red 194 (Red 2BN) dye on jackfruit peel activated carbon (JPAC) is 32.271 mg/g, and JPAC/TiO2 is 34.900 mg/g was observed under optimum conditions. Desorption efficiency of JPAC/TiO2 (≥93.4%) is slightly higher compared to JPAC (≥89.2%). Tannery effluents of various parameters were analyzed, and their chemical oxygen demand (COD) values trim down within the permissible limits of JPAC (97%) and JPAC/TiO2 (98%). Experimental data were studied using both two-parameter and three-parameter models of adsorption isotherm, namely, the Langmuir, Freundlich, Temkin, Dubinin-Radushkevich, Redlich-Peterson, Sips, Toth, and Khan. In which the Langmuir isotherm ( R 2 = 0.9824 ) best described the experimental data with an optimum monolayer capacity for adsorption capacity of 49.7 mg/g at 323 K on Red 2BN molecules. A proposed scheme of Red 2BN molecules on the active sites of adsorbents was illustrated. Regeneration of spent carbons was studied through different cycles of the run.
Remote Laboratories for Teaching and Training in Engineering

Typical mechatronic systems are a combination of advanced technologies involving several disciplines. This multidisciplinary approach to the development of industrial applications provides great opportunities for the implementation of e-learning environments and collaborative schemes. Engineering education, in particular, benefits from many of these advances, among which, virtual instrumentation is a useful tool for the development of virtual environments, e-learning spaces and, particularly, remote laboratories. This chapter describes the implementation of web-based laboratories that allow the remote operation of experiments used as training exercises in undergraduate engineering courses. The remote laboratories were developed using LabVIEW ® software, and they enable remote control and monitoring of laboratory equipment, allowing engineering students to perform experiments in real time, at their own pace, from anywhere, and whenever is suitable for them. Besides the experimental training that the web-based laboratories provide to students, the system is also a powerful teaching tool since real-time demonstrations of the experiments can be performed, and they also can be simultaneously monitored by a group of students. This approach is highly beneficial for engineer - ing schools in developing countries, as resources can be shared through the Internet. A description of the system and three proposed experiments is presented, together with the experimental results.
Customer focus in UK e-government: Or, putting the politics back into e-government

The techniques and technologies of customer service, as introduced under the guise of e-government, have brought certain aspects of public service users into sharp focus, but at the expense of other aspects. It is hypothesised that this effect may lie behind the failure of half a decade of IT-enabled change in public services to improve ‘customer satisfaction’. Remedying this situation, it is suggested, will require a re-examination of the model of the customer which underpins customer service as it has been adopted by public service organisations.
Silicon photodetectors with triple p–n junctions in CMOS technology at 650- and 850-nm wavelengths

A triple p–n junction Si photodetector using 0.25-μm standard CMOS process at 650- and 850-nm wavelengths is presented and investigated. Triple p–n junctions are formed vertically by n+-implant/p-well (N+/HVPW), p-well/n+-buried layer (HVPW/NBL), and n+-buried layer/p-substrate (NBL/P-sub) junctions to attain a wavelength-dependent response. The responsivity and pulse response were characterised in different bias schemes. Measured photocurrents from HVPW/NBL and NBL/P-sub junctions under reverse biasing and a floating electrode on N+-HVPW showed the smallest FWHM values. The −3 dB bandwidth of 1.9 GHz converted from pulse measurement is the highest result ever reported in 654-nm wavelength using standard CMOS technology. The proposed triple p–n junction Si photodetector with bias schemes shows combined excellent performance in 650- and 850-nm wavelengths.

Analysis of Driver Gaze and Attention to Traffic Signs

A driver’s actions and intent can be factors in enabling advance driver assistance systems (ADASs) to assist drivers and avoid accidents. A driver’s gaze can provide insight into the driver’s intent or awareness of situations. Knowing that a driver gazed at a traffic sign or missed a traffic could provide indications of whether the driver is alert to impending changes in the driving environment, such as curves and stop signs. For ADASs to determine the importance of a driver seeing or missing a sign, it is important to understand the driving environment and situation. A first step is to understand what signs drivers do see or miss while driving. This contribution presents the results of analyzing driving sequences to assess traffic signs that drivers may or may not have gazed upon. The results suggest that drivers may miss 20% of traffic signs though the percentage varies depending on the type of sign. The analysis uses image sequences of the driving environment and gazes data captured during driving. The methods used in our analysis included determining whether a driver’s gaze has fallen on the image of a traffic sign or not and subsequently determining signs missed during driving. The methods presented can be useful in other scenarios involving the analysis of driver gaze and have implications for the design of future ADASs and for understanding of driver gaze and awareness.
