UV-C LEDs for Food Safety

As a response to continued public health concerns about food safety, the disinfection of food, its packaging and food preparation surfaces are just a few examples of the diverse applications being contemplated for the wider installation of germicidal ultraviolet solutions among different points along the safe food delivery chain. UV-C disinfection is a proven technology that can offer an economically-sound, effective and versatile dry-processing technology, which could improve plant and consumer safety, extend shelf life and avoid spoilage and waste. With the continued improvement in UV-C LED performance, significant opportunities exist to design flexible and configurable solutions effectively, innovatively providing new processes, while advancing appropriate validation and verification methods and approaches. Introduction According to the Centers for Disease Control (CDC), when two or more people get the same illness from the same contaminated food or beverage source, the event is called a foodborne disease outbreak. In 2013, the CDC reported that 46% of such events were directly attributable to contaminated fresh-cut produce (Painter et al. 2013). What had been touted as the cornerstone of a healthy American diet, three servings of fruits and vegetables daily, was instead, when improperly sanitized, understood to be a potential public health hazard. Although it was acknowledged that healthy foods must be safeguarded, not much has changed since. Recently, Food Safety News (2017) noted that pathogen laden fresh produce still remains among the top public health concerns after yet another leafy green recall. On April 19, 2018, the New York Times (2018) reported contaminated cut romaine lettuce, harvested in Yuma, Arizona, continues to cause serious illness, and one reported death, across many states unabated. Particularly problematic is the contamination of apples, cucumbers, and the aforementioned leafy greens by pathogenic bacteria, such as salmonella, listeria and E. coli O157:H7. Contamination can be introduced at various points along the food handling spectrum from production, through harvesting and processing, and then transport, storage or during display or preparation, ultimately infecting unprotected consumers (Nüesch-Inderbinen and Stephan 2016). The encouraging news is that because of such concerns, efforts into improving methods to effectively reduce and eliminate disease causing pathogens and food spoilage organisms have increased substantially at intervention points along the supply chain. Investigations have particularly focused on microbial reductions closer to the production, since when contamination happens early in the production or processing cycle, the ripple effect of outbreaks becomes wider spread. Unfortunately, arising from increased imports, lax controls as new food delivery mechanisms emerge and the high volume of food processed, contaminated food continues Figure 1.

Yield Improvement in Memory Compiler Generated SRAM with Inter-Die Variations

As the technology scales down to nanometer, the yield degradation caused by inter-die variations is getting worse. Using adaptive body bias is an effective method to eliminate the yield degradation, however we need to know a die having high threshold voltage or low threshold voltage (also called process corner) in order to use this technique. Unfortunately, it is hard to detect the process corner when PMOS and NMOS variations are uncorrelated. In this paper, we propose some improved circuits of delay monitor and leakage monitor for both PMOS and NMOS, which are uncorrelated in inter-die variations. The experimental results show that our circuits can clearly distinguish each process corner of PMOS and NMOS, thus improve the yield obviously by adopting correct body bias.
Effect of sufentanil analgesia for hip replacement on pain mediator , stress hormone and inflammatory cytokine secretion

Hip replacement is a common surgical approach for clinical treatment of hip fractures, and the early postoperative rehabilitation of affected-side limb can help to promote the recovery of limb function. However, significant incision pain after hip replacement will affect the activity of the affected-side limb, which is not conducive to the early rehabilitation exercise. In clinical practice, effective postoperative analgesia is needed to create favorable conditions for limb activity after hip surgery[1,2]. Fentanyl and sufentanil are clinical common opioid analgesics that can excite μ receptors to exert analgesic effect. Sufentanil is a new type of opioid, and its chemical essence is the derivative after fentanyl N-4 substitution. The lipotropism of sufentanil is twice as much as that of fentanyl, and it is easier to pass through the membrane and bloodbrain barrier and act on nerve tissue, so it can exert a more powerful analgesic effect[3]. In the following studies, we specifically analyzed the effects of sufentanil and fentanyl analgesia for hip replacement on pain mediator, stress hormone and inflammatory cytokine secretion.
EasyChair Preprint No 402 Modeling and controller design for a Conical tank process using Radial Basis Function neural network

The major issue in the process industry is to control the level of the liquid in the nonlinear processes especially in a conical tank. This study addresses the efficient controller design for the conical tank process. The conical tank is divided into different operating zones and the approximated first order process model (FOPDT) was identified for each region using simple black box technique. A neural network model based on radial basis fucntion (NNRBF) was found from the FOPDT model. For the identified network, predictive controller (NMPC) was proposed using NNRBF. The performance indices and time domain specifications of the proposed controller are compared with the conventional direct synthesis PI controller (DSPI) and internal model controller (SIMC). The result showed that proposed predictive controller is more effective and robust compared with the other controllers.
Ultrasonography of the Lung Ultraschall der Lunge

Background High diagnostic accuracy, increasing clinical experience and technical improvements are good reasons to consider lung ultrasound (US) for the assessment of pleural and pulmonary diseases. In the emergency room and in intensive care, it is well acknowledged, but application in other settings is rare. The aim of this review is to update potential users in general radiology about the diagnostic scope of lung US and to encourage more frequent use of this generally underestimated lung imaging modality. Method Literature review was done independently by the two authors in MEDLINE (via PubMed) covering a time span from 2002 until 2017 using free text and Medical Subject Headings/MeSH. Article selection for the bibliography was based on consensus according to relevance and evidence. Results and Conclusion The technical prerequisites include a standard ultrasound unit with a suitable transducer. Pleural effusion and pneumothorax, atelectasis, interstitial edema, pneumonia, exacerbated chronic obstructive pulmonary disease/asthma and pulmonary embolism can be distinguished by particular ultrasound signs, artifacts and their combinations. A highly standardized selection of access points and terminology for the description of imaging findings contributes to high diagnostic accuracy even in challenging patients and settings. Besides the assessment of acute respiratory failure in the emergency room, lung US may be used for monitoring interstitial fluid accumulation in volume therapy and for the diagnosis of pneumonia or the assessment of pleural effusion and pleurisy in a routine outpatient setting. Last but not least, the increasing concerns about medical radiation exposure warrant a more extensive use of this sometimes underestimated modality as a cost-, timeand radiation-saving alternative or valuable adjunct to the standard imaging modalities. Key Points: ▪ Lung US is a safe, quick and readily available method with options for dynamic imaging of respiratory function. ▪ Proper selection of technical parameters customized to the clinical question and standardized terminology for the precise description and interpretation of the imaging signs regarding patient history determine its diagnostic accuracy. ▪ In dyspnea lung US differentiates pneumothorax, lung edema, pneumonia, pulmonary embolism, atelectasis and
EVALUATION OF WEAR AND FRICTION MECHANISMS OF DIFFERENT PISTON RING AND CYLINDER LINER MATERIALS

In the field of engine development one has to meet constantly growing requirements due to fuel consumption restrictions, weight reduction and emission standards, often combined with supercharged motors. These requirements lead to higher stresses of material components. Especially contact stresses of cylinder liner / piston ring surfaces are increased. Particularly, dead center areas are highly stressed, since hydrodynamic friction changes into boundary friction. This paper deals with modelling boundary lubrication using a reciprocating test rig. The influence of different lubrication modes on friction and wear of selected cylinder liner and piston ring materials is examined.
Adherence to antiretroviral therapy and its determinants in children with HIV infection – Experience from Paediatric Centre of Excellence in HIV Care in North India

The objective of this study is to assess adherence to antiretroviral therapy (ART) in HIV-infected children using the pill count method, and determine factors leading to adherence failure. Records of 106 children living with HIV (CLHIV) age <15 years and on ART for >6 months were reviewed. Average adherence to ART by pill count method over preceding six months was calculated and re-assessed by 3-day recall method. The caregivers of 105 children and one child himself were interviewed about the problems encountered while giving ART. Median age of enrolled children was 104 (inter-quartile range [IQR] 77.3–133.8) months. Median duration of ART was 25 (IQR 16–35) months. The desired adherence level of >95% during six months of review assessed by pill count was achieved in 95.3% children. The 3-day recall method yielded >95% adherence in 99% children (p ≤ .001). Caregivers of 59 children (56.2%) reported multiple problems while administering drugs. In most instances, problems encountered were related to family/caregivers, the commonest being multiple caregivers, job constraints and death/illness in the family. In conclusion, we found a very high level of adherence to ART in CLHIV. Poor adherence was mainly associated with issues related to the family/caregivers.
Tetracycline and chloramphenicol studies on rabbit and human eyes.

It has been observed that those antibiotics which penetrate into the spinal fluid through the so-called blood-brain barrier also penetrate into the eye through the blood-aqueous barrier. Recent reports in the literature have indicated that tetracycline penetrates into the spinal fluid in animals1and in humans.2 As no other report concerning the intraocular penetration of tetracycline has been published up to this time, we considered it of value to determine the degree of penetration of this antibiotic into the aqueous humor of rabbits and human beings. It was considered of importance to use human as well as rabbit eyes, for there have been very few reports on the intraocular penetration of antibiotics into human eyes, the supposition having been that rabbit eyes were very similar to human eyes in this respect. Various modes of administration and dosage schedules were utilized. Also, a small number of assays were performed
Cardiopulmonary response to inhalation of biogenic secondary organic aerosol

An irradiation chamber designed for reproducible generation of inhalation test atmospheres of secondary organic aerosol (SOA) was used to evaluate cardiopulmonary responses in rodents exposed to SOA derived from the oxidation of α-pinene. SOA atmospheres were produced with 10:1 ratios of α-pinene:nitrogen oxides (NOx) and 10:1:1 ratios of α-pinene:nitrogen oxides:sulfur dioxide (SO2). SOA atmospheres were produced to yield 200 μg m−3 of particulate matter (PM). Exposures were conducted downstream of honeycomb denuders employed to remove the gas-phase precursors and reaction products. Nose-only exposures were conducted with both rats (pulmonary effects) and mice (pulmonary and cardiovascular effects). Composition of the atmospheres was optimized to ensure that the SOA generated resembled SOA observed in previous irradiation studies, and contained specific SOA compounds of interest (e.g., organosulfates) identified in ambient air. Pulmonary and cardiovascular toxicity were measured in two different rodent species. In situ chemiluminescence and thiobarbituric acid– reactive substances (TBARS) were used to evaluate oxidative reactions in the F344 rats. ApoE−/− mice were exposed for 7 days and measurements of TBARS and gene expression of heme oxygenase-1 (HO-1), endothelin-1 (ET-1), matrix metalloproteinase-9 (MMP-9) were made in aorta. Pulmonary inflammatory responses in both species were measured by bronchoalveolar lavage fluid (BALF) cell counts. No pulmonary inflammation was observed in either species. A mild response was observed in mouse aorta for the upregulation of HO-1 and MMP-9, but was not seen for ET-1. Overall, α-pinene–derived SOA, including SOA that included organosulfate compounds, revealed limited biological response after short-term inhalation exposures
SYSTEMATICS OF FEJERVARYA CANCRIVORA COMPLEX FROM INDONESIA AND OTHER ASIAN COUNTRIES BASED ON ALLOZYME AND MOLECULAR TECHNIQUES , MORPHOLOGICAL OBSERVATIONS AND CROSSING EXPERIMENTS

– The crab-eating frog, Fejervarya cancrivora is widely distributed in Asia, thus cryptic species might occur in this group. In order to elucidate the genetic divergence, evolutionary relationship and taxonomic status in F. cancrivora, allozyme and molecular analyses were carried out from 24 populations of frogs in Indonesia, Thailand, Bangladesh, Malaysia and the Philippines. Five populations of F. cancrivora from Selangor, Cianjur, Trat, Khulna and Makassar were examined morphologically and subjected to crossing experiments. Allozyme and molecular analysis of 16S rRNA and Cyt b genes revealed three groups of F. cancrivora, here dubbed large-type, mangrove-type and Pelabuhan ratu/Sulawesi-type. In addition, PCA and clustering analyses revealed that the five populations can also be separated into three groups: large-type, mangrove-type and Sulawesi-type. The limited crossing experiments showed that the hybrids between Selangor females and Cianjur and Trat males developed normally, whereas the hybrids between Selangor females and Khulna males showed incomplete gametic isolation. It was concluded that each of three identified types represents a distinct species that comprised the large-type F. cancrivora, the mangrove-type F. moodiei, and a yet undescribed species of Sulawesi-type.
Fast Extraction of High‐quality Crease Surfaces for Visual Analysis

We present a novel algorithm for the efficient extraction and visualization of high‐quality ridge and valley surfaces from numerical datasets. Despite their rapidly increasing popularity in visualization, these so‐called crease surfaces remain challenging to compute owing to their strongly nonlinear and non‐orientable nature, and their complex boundaries. In this context, existing meshing techniques require an extremely dense sampling that is computationally prohibitive. Our proposed solution intertwines sampling and meshing steps to yield an accurate approximation of the underlying surfaces while ensuring the geometric quality of the resulting mesh. Using the computation power of the GPU, we propose a fast, parallel method for sampling. Additionally, we present a new front propagation meshing strategy that leverages CPU multiprocessing. Results are shown for synthetic, medical and fluid dynamics datasets.
The hypercalcemia of cancer. Clinical implications and pathogenic mechanisms.

HYPERCALCEMIA is one of the most common metabolic complications of cancer. It has fascinated clinicians since it was first recognized 60 years ago by Zondek et al.1 It is now being recognized more commonly, as is primary hyperparathyroidism, because of the advent of routine measurement of the serum calcium level.2 , 3 The estimated incidence of the hypercalcemia of cancer is 150 new cases per million persons per year.2 , 3 This compares with an annual incidence of approximately 250 new cases of primary hyperparathyroidism per year.2 , 3 However, the relative frequency of cancer as a cause of hypercalcemia is even greater in hospital populations, .
PERFORMANCE EVALUATION OF MIMO-OFDM IMPLEMENTATION ON WIRELESS OPEN-ACCESS RESEARCH PLATFORM ( WARP )

Spatial diversity technique known as multiple-input-multiple-output (MIMO) and multi-carrier modulation technique, one of which is an orthogonal frequency division multiplexing (OFDM) technique, is two candidate techniques that are suitable for use on high-speed data transmission in the future. OFDM technique uses a large number of sub-carriers to overcome the effects of frequency selective fading and using cyclic-prefix to suppress inter-symbol-interference (ISI) caused by multipath propagation. The duration of the cyclic-prefix should be longer than the delay-spread of the multipath channel, so that ISI can be removed completely. The application of MIMO diversity techniques on the OFDM system will improve system performance significantly. By using MIMO techniques, many propagation path will be available. These propagation path are departing from a number of antennas on the transmitter side toward a number of antennas on the receiver side directly. Therefore, if there is a severe distortion signals coming out from one of propagation-path then the system may rely on other signals from other propagation-path. Thus the possibility of errors that may occur can be prevented. Furthermore, to increase the diversity of the fading effect, in this study, we use space-time coding-block-code (STBC) Alamouti. This paper aims to study the combined performance of MIMO-OFDM technique when applied to the Wireless open-Access Research Platform (WARP) module, which is one of the software defined radio (SDR) device. The MIMO-OFDM system performance isanalyzed and compared to the MISO-OFDM system, both system use quadrature phase shift keying (QPSK) modulation scheme.
The Influence of Physical Cell Parameters on Projection Cytometer Measurements

In this paper the influence of optical absorption on projection cytometer measurements is discussed. Projection cytometry is an optical method for measuring physical parameters of biological cells in the optical near field. For reliable results, it is crucial to keep the projection distance constant for consecutive measurements which is achieved by applying a non-coaxial sheath flow. Simulations have been performed to predict the sensor signal for different absorption coefficients inside a cell. The interesting result is that with changing absorption coefficient only a part of the signal shape changes which indicates the ability to extract this parameter from the shape of the signal.
The behavior of brain and retinal tissue in mortality of the early chick embryo

Patten ( ’52) has described the occurrence of infoldings of the brain and retina in young aborted human embryos and in the pig embryo. His interpretation of the abnormality is that the infoldings occur as a result of abnormal growth of the brain and retinal neural tissue during early development. He designates the finding “overgrowth of the neural tube. ” Sjodin and Browning ( ’52) observed similar infoldings in the brains and retinas of chick embryos dying from exposurc to an oxygen tension of 13% at the 4to 6-day stage. Embryos were incubated for 4 days and subjected to hypoxia for two days. About half of these died after one to two days in the hypoxic environment. The half which survived the exposure appeared normal in histological sections. Only embryos which died from the treatment showed infoldings (figs. 1 and 2). One should note that in the retina, only the central neural layer is involved in the infolding. The pigment layer shows only a minor degree of distortion. This detail agrees with Patten’s observations. Before proceeding with an experimental analysis of the anomaly, it seemed advisable to investigate the possibility of its occurrence in embryos dying routinely in normal incubations. Several embryos dying at the 4to &day stage
