Prevalence of some deteriorating microorganisms in raw milk and some locally made cheese

Food deterioration has become a very important issue as excessive amounts of food are lost due to microbial spoilage. The work aimed to assess the microbiological quality of raw milk and soft locally made cheeses in Assiut city, Egypt. A total of one hundred and fifty random samples of raw bovine milk (90 samples) and locally made cheese including Kareish and Domiati cheese (30 samples each) were collected randomly from different localities in Assiut city, Egypt. These samples were examined for microbiological evaluation. The investigation revealed that the average APC were 1.9×10, 2.6×10, 6.2×10, 7.5×10 and 1.8×10 cfu/ml or /g for dairy farm milk, dairy shops, street vendor raw milk, Kareish cheese and Domiati cheese, respectively and the average Psychrotrophic count was 8.3×10, 1.0×10, 1.5×10, 2.5×10 and 9.0×10 cfu/ml or /g while the average Proteolytic count was 1.6×10, 2.1×10, 3.7×10, 5.3×10 and 2.0×10 cfu/ml or /g. Additionally, the average Lipolytic count was 2.5×10, 3.9×10, 6.5×10, 9.8×10 and 2.8×10 cfu/ml or /g for the above-mentioned samples respectively. On the other hand, the Lactobacillus counts were 5.5×10, 8.8×10, 1.4×10, 1.9×10 and 5.2×10 cfu/ml or /g, respectively. The average count of total yeast and molds were 9.5×10, 2.5×10, 7.5×10, 7.5×10 and 6.2×10 cfu/ml or /g, respectively. In conclusion, the presence of these organisms indicted that the examined samples were of low quality which reflect unhygienic measures during milking, processing, storage, and distribution chain.

The authors developed a room temperature liquid phase silylation process using Bis(dimethylamino)dimetylsilane (B[DMA]DS), which had been reported as the highest contrast silylation agent in the i-line DESIRE process. This paper describes the potential of the 193 nm lithography for 0.15 /spl mu/m rule and discuss process capabilities. Room temperature liquid phase silylation with B(DMA)DS was applied to 193nm ArF excimer laser lithography, 0.14 /spl mu/m resolution was acheived with a conventional binary mask. It is demonstrated that 193 nm is the most promising method for 1-4G DRAMs fabrication. <<ETX>>
Dependence of Relaxation Time on the Core Size Two-Phase Nanoparticles Magnetite/Titanomagnetite

In this paper, depending of the blocking temperature on magnetite core size for core/shell nanoparticles has been carried out using our theoretical model. Nanoparticles has size of 100nm, and magnetite core increases from 0nm to 100nm. Systems were studied with different values of exchange constant. The data obtained indicate that exchange constant increases the blocking temperature. However, the sign of the constant does not matter.
A Qualitative Study Comparing the Experiences of the Meditation-Based Lifestyle Modification Program with Multi-professional Psychiatric Treatment for Female Outpatients with Mild to Moderate Depression

Meditation-Based Lifestyle Modification (MBLM) is a complex eight-week mind-body intervention based on the traditional eight-fold path of classical yoga. MBLM was developed for mental health care, and it combines ethical living, physical yoga, and meditation. In this qualitative study, the subjectively perceived efficacy of MBLM was compared to the perceived efficacy of an individually tailored, multi-professional psychiatric treatment (MPT) in a psychiatric outpatient clinic. Twelve patients were interviewed for this study (six for each condition). All qualitative interviews were analyzed using thematic analysis. In total, five main themes with associated subthemes emerged from the data: calmness, increased awareness, interpersonal relationships, depressive symptoms, and difficulties within the therapy. Moreover, our study showed significant differences between the two therapy groups. First, the groups differed regarding the frequency with which various topics were addressed by the patients. Second, the perceived effectiveness of both therapies (MBLM vs. MPT) varied according to descriptions of the perceived changes in each participant. The participants in the MBLM program generally appeared to experience a deeper emotional-experiential integration which contrasted with the more cognitive-behavioral processing of the MPT patients. These findings may guide further research and the implementation of similar complementary therapies in psychiatry.
Transcatheter Arterial Embolization as a Treatment for Life-Threatening Retroperitoneal Hemorrhage in COVID-19 Patients on Anticoagulant Therapy

Retroperitoneal hemorrhage is a possible complication that has been noticed in COVID-19 patients on anticoagulant therapy. The data related to treatment and outcomes in this condition are scarce. We present a case series of four COVID-19 patients with lumbar artery bleeding, who were treated with transcatheter arterial embolization using embolization particles. The procedure was executed without any complications, and hemostasis was achieved in all four patients. Despite the patients survived the procedure, one patient died due to respiratory failure three weeks after the procedure, and one died due to hypovolemic shock two days later. Considering the ongoing state of COVID-19 pandemic, it is essential to be aware of transcatheter arterial embolization as a safe and effective procedure for treating retroperitoneal hemorrhage in COVID-19 patients.
Contact interface fiber section element: shallow foundation modeling

With recent growing interests in the Performance-Based Seismic Design and Assessment Methodology, more realistic modeling of a structural system is deemed essential in analyzing, designing, and evaluating both newly constructed and existing buildings under seismic events. Consequently, a shallow foundation element becomes an essential constituent in the implementation of this seismic design and assessment methodology. In this paper, a contact interface fiber section element is presented for use in modeling soil-shallow foundation systems. The assumption of a rigid footing on a Winkler-based soil rests simply on the Euler-Bernoulli`s hypothesis on sectional kinematics. Fiber section discretization is employed to represent the contact interface sectional response. The hyperbolic function provides an adequate means of representing the stress-deformation behavior of each soil fiber. The element is simple but efficient in representing salient features of the soil-shallow foundation system (sliding, settling, and rocking). Two experimental results from centrifuge-scale and full-scale cyclic loading tests on shallow foundations are used to illustrate the model characteristics and verify the accuracy of the model. Based on this comprehensive model validation, it is observed that the model performs quite satisfactorily. It resembles reasonably well the experimental results in terms of moment, shear, settlement, and rotation demands. The hysteretic behavior of moment-rotation responses and the rotation-settlement feature are also captured well by the model.
Soil loss and PM10 emissions from agricultural fields in the Junggar Basin over the past six decades

The Junggar Basin in north Xinjiang Province is regarded as one of the important dust sources in China. There is, however, a lack of information on long-term dust emissions originating from the basin. In these largely agricultural communities, wind erosion is a major concern that results in a threat to sustainable agriculture and environmental quality. This study assesses dust emissions from the agricultural community of the Junggar Basin in north Xinjiang based on soil and land use types extracted from remote sensing data in response to weather and climate over the past six decades. The Wind Erosion Prediction System (WEPS) was used to simulate annual soil loss and PM10 (particulate matter ≤10 μm in aerodynamic diameter) emissions at 11 meteorological stations across the Junggar Basin. From 1958 to 2018, annual soil loss and PM10 emissions significantly decreased 3.65 and 0.2 kg m–2 y–1, respectively. This decrease was likely due to decreasing wind speed, but also associated with increased precipitation and temperature, and decreased solar radiation. Wind erosion occurred most frequently during April and May, accounting for 39% of the annual soil loss and 40% of the annual PM10 emission. In contrast, no erosion occurred in January, February, and December as a result of low temperature (<–8.6°C), frozen soil conditions, and snow cover. Wind erosion risk appeared to decrease during the past six decades in response to observed climate change across the basin; however the southeast part of the basin experienced increasing wind erosion risk over the six decades. Projects to control wind erosion risk and combat dust emission should be given priority in the southeast part of the basin. Frequency of dust events was compared to simulated erosion; a strong linkage was found between simulated soil loss and frequency of dust storms based on regression analysis. This demonstrated that the modelling was acceptable in the conditions of this study and the results were prone to be reliable.
Differences in perinatal outcomes in teenage mothers with their first and third pregnancies and predictors of adverse neonatal events: A cross-sectional study

Abstract Background Repeated teenage pregnancy is a major burden on the healthcare system worldwide. Objective We aimed to compare teenagers with their first and third pregnancies and to evaluate the likelihood of neonatal complications. Materials and Methods This cross-sectional study was performed on female teenagers (aged ≤ 19 yr) with singleton pregnancies. The subjects (n = 298) were screened over 12 months. Ninety-six women were excluded, based on the exclusion criteria. The remaining subjects (n = 202) were divided into two groups: teenagers with first pregnancy (n = 96) and teenagers with third pregnancy (n = 47). The subjects were observed throughout pregnancy and delivery. The final sample size of the first and third pregnancy groups was 96 and 47, respectively. Results There was a significant risk of preeclampsia in the first pregnancy group (p = 0.01). Low birth weight, five-min Apgar score < 7, and neonatal intensive care unit admission were the most significant neonatal outcomes in the first pregnancy group. In the third pregnancy group, significant predictors of neonatal complications included very young age in the first pregnancy ( ≤ 15 yr), an inter-pregnancy interval < 2 yr, current anemia, and history of obstetric and/or neonatal complications in previous pregnancies. Conclusion Based on the results, teenagers with their first pregnancy had comparable obstetric outcomes (except for preeclampsia) as teenagers with their third pregnancy, whereas neonatal complications occurred more frequently in the first pregnancy group. Overall, we can predict high-risk neonates in the third pregnancy, based on the abovementioned parameters.
Optimal Guidance of a Relay MAV for ISR Support Beyond Line-of-Sight

This paper focuses on developing guidance laws to optimally position a relay Micro Aerial Vehicle (MAV) to provide an operator with real-time Intelligence, Surveillance, and Reconnaissance (ISR) by relaying communication and video signals when there is no LineOf-Sight (LOS) between the operator at the base and the rover MAV performing the ISR mission. The ISR system is comprised of two MAVs, the Relay and the Rover, and a Base. The Relay strives to position itself so as to minimize the radio frequency (RF) power required for maintaining communications between the Rover and the Base, while the Rover performs the ISR mission, which may maximize the required RF power. The optimal control of the Relay MAV then entails the solution of a differential game. Applying Pontryagin’s Maximum Principle yields a standard, albeit nonlinear, Two-Point Boundary Value Problem (TPBVP). Suboptimal solutions are also analyzed as an aid in solving the TPBVP which yields the solution of the differential game. One suboptimal approach is based upon the geometry of the ISR system: The midpoint between the Rover and the Base is the ideal location which minimizes the RF power required, so the Relay heads toward that point— assuming that the Rover is stationary. At the same time, to maximize the required RF power, the Rover might move such that the midpoint travels in the opposite direction of the Relay—assuming the Relay is stationary. Thus, the Rover heads away from the Relay on a course parallel to that of the Relay. Another suboptimal approach investigated envisions the Rover to remain stationary and solves for the optimal path for the Relay to minimize the RF power requirement during the planning horizon. This one-sided optimization problem is analyzed using a Matlab-based optimization program called GPOCS, which uses the Gauss pseudospectral method of discretization. The results from GPOCS corroborated with the geometry-based suboptimal approach, showing that the optimal path for the Relay is to head straight toward the midpoint between the Rover and the Base.
Why is it so difficult to tax the rich? Evidence from German policy-makers

ABSTRACT Why are rich citizens not taxed more heavily – despite growing inequality (aversion)? The literature offers several explanations, all of which ultimately work through the minds and actions of politicians. Taking Germany as a case, we therefore ask in 25 semi-structured interviews which obstacles left-wing politicians perceive in taxing the rich. Overall, tax increases are perceived as difficult projects. Organized business is described as a major barrier, but in a way that goes beyond existing accounts: besides classical lobbying, business interests are seen to influence electoral politics through long-term communication strategies shaping tax preferences. Moreover, the interviews point to a previously unrecognized organizational barrier that we coin the ‘vicious competence cycle’: left-wing politicians are often overwhelmed by tax issues which results in consequential disadvantages when confronted with resourceful anti-tax actors. They describe how party-internal discourses shape these competence patterns by influencing motivations, feasibility perceptions, and electoral strategies.
Journalists as mobility agents: Labor mobilities, individualized identities, and emerging organizational forms

As mobility is becoming a distinctive feature of 21st century journalists, this theoretical article proposes a mobility turn in journalism studies. Drawing on sociological perspectives on mobilities, individualization, and turnover, it puts forward a shift from the analysis of news workers as static and fixed to the organizations that employ them to their analysis as mobility agents. By stressing that their capacity to move is transforming their employment and identities, it invites contemporary journalism scholars to recognize how this bottom-up disruption is reshaping the institution, the organizations and the labor of journalism. Since journalism’s corporate and industrial structures have not fully crumbled, this article’s emphasis on labor, physical and virtual mobilities offers an alternative to current theorizations of change in journalism.
Residual displacement estimation of the bilinear SDOF systems under the near-fault ground motions using the BP neural network

This paper presents a comprehensive study of residual displacements of the bilinear single degree of freedom (SDOF) systems under the near-fault ground motions (NFGMs). Five sets of NFGMs were constructed in this study, in which the natural ones as well as the synthesized ones were both considered. By way of the nonlinear time history analyses, three different residual displacement spectrums were obtained and analyzed in detail. Utilizing the calculated data, a back propagation (BP) neural network was established to predict the residual displacements of the bilinear SDOF systems under the NFGMs. The results show that the structural parameters, including the strength reduction factor and the post-yield strength ratio, have significant and relatively consistent impacts on the residual displacement spectrum. However, the ground motion characteristics, including the fault type, the closest distance from the site to the fault rupture, the earthquake magnitude, and the site soil condition, exhibit more complex effects on the residual displacement spectrum. In addition, the proposed BP neural network can fully incorporate the parameters affecting the residual displacements of the bilinear SDOF systems under the NFGMs, while having a fairly good accuracy in predicting the residual displacements.
Endemic infections of bovine viral diarrhea virus genotypes 1b and 2a isolated from cattle in Japan between 2014 and 2020

Bovine viral diarrhea virus (BVDV) is a causative agent of bovine viral diarrhea. In Japan, a previous study reported that subgenotype 1b viruses were predominant until 2014. Because there is little information regarding the recent epidemiological status of BVDV circulating in Japan, we performed genetic characterization of 909 BVDV isolates obtained between 2014 and 2020. We found that 657 and 252 isolates were classified as BVDV-1 and BVDV-2, respectively, and that they were further subdivided into 1a (35 isolates, 3.9%), 1b (588, 64.7%), 1c (34, 3.7%), and 2a (252, 27.7%). Phylogenetic analysis using entire E2 coding sequence revealed that a major domestic cluster in Japan among BVDV-1b and 2a viruses were unchanged from a previous study conducted from 2006 to 2014. These results provide updated information concerning the epidemic strain of BVDV in Japan, which would be helpful for appropriate vaccine selection.
Interference fit fastener inspection using sonic thermography

Abstract This paper reports on an experimental study addressing the application of sonic thermography to the characterisation of interference fit levels in fastened metallic plates. The technique uses high intensity acoustic waves to induce frictional heating at defect locations. In the case of poorly fitted interference fasteners, the acoustic waves induce relative motion between the fastener and host, causing frictional heating that is detected with a thermal imaging system. Results are shown to demonstrate the efficacy of the approach.
Features of the decidualized endometriosis diagnosis and course during pregnancy

Currently, surgical treatment aimed to exclude the malignant ovarian tumors is performed in almost 90% of patients with decidualized endometrial cysts (DEC). However, unnecessary surgical interventions increase the risk to maternal and fetal health. The study was aimed to perform a differential diagnosis of DEC in pregnant women in order to define the rational treatment. A total of 82 female patients were included in the study: 63 had endometrial cysts (EC), 16 had DEC, 3 had rare forms of endometriosis, and 10 had ovarian serous papillary borderline tumors. When performing the diagnostic ultrasound, our proposed model was used. The ultrasound imaging data obtained were juxtaposed with the concentration of the protein tumor markers (СА-125), the risk of malignancy index (RMI) was calculated, and the morphological assessment of the masses was performed. The ultrasound imaging parameters, being the most valuable for differential diagnosis of EC, DEC, and serous borderline tumors, were as follows: the altered mass wall thickness, the existence and shape of papillary masses, avascular echogenic inclusions with blurry contour, blood circulation and arrangement of blood vessels, ascites. The frequency analysis revealed the differences between groups based on the ultrasound imaging data (in 60–100% of observations). Histological examination revealed the differences between groups in 100% of observations. Our findings have made it impossible to prolong pregnancy in patients with DEC without performing surgery. The results of treatment provided to patients with DEC during pregnancy were worse compared to those in patients with no prominent decidualization in ovarian EC. Today, the diagnosis of DEC and the treatment of patients during pregnancy remain unsophisticated. Further clinical observation and the search for more reliable methods of the diagnosis and rational treatment of pregnant women with DEC are required.
Routing in Industrial Wireless Sensor Networks: A Survey

Recently, industrial wireless sensor networks have attracted more attention, due to their large benefits in terms of faster installation, cost savings, and flexibility. Nevertheless, the acceptance of wireless sensor networks by the industrial community is not without its difficulties. In fact, several research efforts have been made in this field and a number of state-of-the-art reviews exist, presenting the current standards, the challenges, and the design principles. However, a comprehensive review on routing protocols appears to be missing. In this paper, we give a survey on routing protocols for industrial monitoring applications of the wireless sensor networks technology, and we present their limitations and weaknesses according to the industrial requirements.
Fiber Bragg-grating incorporated microbend sensor for simultaneous mechanical parameter and temperature measurement

We propose a compact microbend sensor operating in the reflection mode for simultaneous measurement of a mechanical parameter and the temperature. The sensor is composed of a single-mode fiber lead, a multimode sensing fiber, and a single-mode fiber Bragg grating, where microbending is applied to the multimode fiber for mechanical parameter measurement and the grating provides an additional signal for temperature measurement. The sensor is demonstrated experimentally with two demodulation schemes based on a broad-band source and a tunable laser, respectively. The sensor extends the capacity of a conventional microbend sensor and offers many additional advantages, including higher stability, higher sensitivity, single-end access, and superior multiplexing capability.
Transcranial doppler findings in basilar artery dolichoectasia: a case control study

Basilar artery dolichoectasia (BAD) is a disorder characterized by dilatation, elongation and tortuosity of the basilar artery. Transcranial Doppler ultrasound (TCD) is a useful tool that can detect blood flow in intracranial vessels including basilar artery (BA). Few studies have been conducted on blood flow changes in BAD. This study was conducted to evaluate the Doppler parameters in dolichoectatic BA and to assess if there is any difference in TCD findings between stroke and non-stroke BAD patients. A case-control study was conducted on 35 patients diagnosed with BAD (26 male, 9 female) and 35 age- and gender-matched control group (without BAD) at the Middle Euphrates Neuroscience Center, Al-Sader Medical City, Al-Najaf, Iraq. Dolichoectasia was diagnosed on non-enhanced brain CT scan using established imaging criteria according to Dan Deng et al criteria. Doppler flow for control and stroke cases was recorded. The parameters measured on TCD were peak systolic velocity (PSV), end diastolic velocity (EDV) mean blood velocity (MBV), pulsatility index (PI) and resistive index (RI). After logistic regression for adjustment for the significant confounders, there was statistically significant difference in Doppler parameters between both groups including decrease in each of PSV, EDV and MBV while both PI and RI weren’t statistically significant. Among BAD patients, there was statistically significant difference in all TCD parameters between stroke and non-stroke patients (PSV EDV, MBV, PI and RI). BAD was associated with a decrease in flow velocities as measured by TCD. Furthermore, among BAD patients, those with stroke had lower values for all Doppler parameters than non-stroke patients.
