Biological effects of yoghurt with rosemary on injured liver rats

The present study was designed to investigate the effect of yoghurt supplemented with rosemary powder or extract on injured liver in rats. This was achieved through determination of some biochemical parameters in serum and liver in addition to the histopathological study of liver under different treatments. Forty-nine adult male albino rats Sprague Dawley strain were equally divided into seven groups; a negative control (C-) group; and CCl4-treated rats that included a positive control (C+) and groups that received a dietary supplement of yoghurt, rosemary powder, rosemary extract, yoghurt with rosemary powder or yoghurt with rosemary extract. The results revealed that, CCl4 treatment caused significant decrease in food intake, weight gain, feed efficiency ration, and serum protein, albumin, globulin, and high density lipoprotein (HDLc) and increases in serum bilirubin, albumin/globulin ratio, total cholesterol, triglycerides, low and very low density lipoprotein, and cholesterol/HDLc ratio. The CCl4 treatment also caused increases in liver cholesterol, total lipids, triglycerides, glycogen, malondialdehyde and increased the enzymatic activities of superoxide dismutase, glutathione peroxidase and glutathione transferase, Inclusion of yoghurt, rosemary powder and rosemary extract into the diets of CCl4-treated rats improved the levels of all these biomarkers of liver injury. For example there were significant decreases in serum total bilirubin and significant increases in serum protein and albumin. The most effective dietary treatment was consumption of yoghurt with rosemary extract and the CCl4-treated group receiving this diet typically had biomarker scores that were not significantly different from the negative control group that received the standard diet without any CCl4treatment. Histopathological examination of the rat livers confirmed this amelioration of health showing that consumption of yogurt with rosemary can lower pathological changes in injured liver rats. Our study clearly demonstrated that administration of a combination of yoghurt and rosemary extract (or powder to a lesser extent) alleviates the harmful effect of CCl4- induced liver injury.
Relationships Between Daily Device Use and Early Communication Outcomes in Young Children With Cochlear Implants

Objectives: Children with significant hearing loss can gain access to sound via a cochlear implant (CI), but they must wear the device to reap the communication benefits of the device. That is, poor daily device use may result in underdeveloped perceptual and language skills in children and adolescents using CIs. This retrospective study focuses on the relationship between daily CI use and communication performance (auditory skills, speech recognition, expressive and receptive language) in young children, with the hypothesis that greater daily device use coincides with better communication outcomes. Design: The authors conducted a clinical chart review of patients with CIs younger than 5 years old who used at least 1 CI speech processor with datalogging technology. Participants (n = 65) had a mean chronologic age of 3.5 years, mean implantation age of 1.9 years, and mean device experience of 1.6 years. Approximately one quarter of participants had additional disabilities. Daily device use (i.e., datalogging information), child characteristics (e.g., age at CI), and assessments of communication skills (i.e., parent questionnaires, speech recognition tests, standardized language assessments) were obtained from each child’s records. The investigators performed correlational analyses to examine relationships between communication outcomes and daily device use, and they employed group comparisons and correlations to identify child characteristics that were significantly associated with daily device use (p < 0.05, corrections for family-wise error). Results: Young children with CIs used their device, on average, 6.7 hr/d, with 63% below full-time use (<8 hr/d). Children without additional disabilities who wore their CI more hours per day had significantly better auditory, speech recognition, and language skills. A significant correlation also emerged between daily device use and early auditory skills in young CI users with additional disabilities, though relationships were more complicated for this subsample. Longer daily device use significantly correlated with younger age at CI and longer device experience. Differences in device use occurred in regards to absence versus presence of additional disabilities, bilateral versus unilateral device configuration, sign versus spoken language, and private versus government-assisted insurance. Conclusions: The strong relationship between daily device use and early communication suggests clinicians and parents should focus on increasing the number of hours per day young children wear their CIs to enhance auditory and language outcomes. However, intervention strategies must consider barriers to consistent device use and goals of the family to efficiently and effectively support families of young children with CIs who struggle with inconsistent device use.
STCC: A SDN-oriented TCP congestion control mechanism for datacenter network

Due to characteristics of high bandwidth and low latency, datacenter networks ensure tremendous data could be transmitted in an efficient way. However, in many ‐ to ‐ one transmission scenarios, high concurrency of TCP flows aggravates network congestion and causes overflows in switches, seriously impairing network performance. To solve the problem, a TCP congestion control mechanism based on software ‐ defined networking (STCC) is proposed. Without any modification in TCP stack, STCC monitors network performance through centralized control and global network view of SDN, employs a routing algorithm based on the minimum path bandwidth utilization rate to forward packets and uses different methods to adjust congestion windows of senders so that network congestion can be greatly mitigated. An experiment platform is built to carry out simulation tests for evaluating STCC, and the results show that under the same network conditions, STCC effectively reduces the number of retransmission timeout of senders and noticeably raises network throughput, compared with other congestion control algorithms.
A LOW-PROFILE DUAL-BAND BASE STATION ANTENNA WITH ANTENNA ON ANTENNA STRUCTURE

A low-profile dual-band composite structure antenna is proposed for fifth generation mobile communication system (5G), which is named as Antenna on Antenna (AOA). Loaded with an artificial magnetic conductor (AMC) reflector, the proposed AOA element consists of a pair of dual-polarized lower band (LB) dipole antennas working in the 0.7–1.03 GHz band and four upper band (UB) patch antenna arrays working in the 24.25–27 GHz band, which covers LTE and 5G millimeter wave band. In order to reduce the size of base station antenna, the millimeter wave patch antenna arrays are parasitic on LB dipoles. While the radiator of the LB antenna is utilized as the ground of the millimeter wave patch antenna array, LB and UB antennas share the same dielectric substrate. The profile height of the antenna is reduced by AMC reflector effectively. Meanwhile, the three-element AOA array loaded with AMC reflector is designed to validate the overall performance of base station antenna. The operation bands of the proposed AOA are 0.7–1.03 GHz (Snn < −14 dB) and 24.25–27 GHz (Snn < −10 dB) for LTE and 5G millimeter bands, respectively. Antenna prototype was fabricated and measured to verify the design solution. The measured results which are consistent with simulated results show that the AOA has good impedance matching, port isolation, and stable radiation pattern.
The effectiveness of tensioning neural mobilization of brachial plexus in patients with chronic cervical radiculopathy: a randomized clinical trial

Introduction. Tensioning neural mobilization (NM) is accomplished through increasing the distance between nerve bed ends via elongation. NM techniques have different biomechanical effects on the nervous system. Evidence for their use in treating certain upper-quarter conditions like cervicobrachial pain is limited. The study was to determine tensioning NM efficacy on unilateral chronic cervical radiculopathy regarding mechanosensitivity of the affected nerve roots and intensity of neck and arm pain. Methods. Forty participants with chronic unilateral cervical radiculopathy were randomly assigned to group A (n = 20), receiving traditional physical therapy (manual traction and infrared irradiation), and group B (n = 20), receiving traditional physical therapy in addition to tensioning NM of brachial plexus. Mechanosensitivity of the affected brachial nerve roots and intensity of neck and arm pain were evaluated at baseline and after a 3-week program with the upper limb tension test-1 and visual analogue scale. The normal (Z) test, paired and unpaired t-test, Wilcoxon signed-rank test, and Wilcoxon rank-sum test (Mann-Whitney) were used in data analysis. Results. There were significant within-group differences in both groups regarding mechanosensitivity and pain intensity (mechanosensitivity: p = 0.001 for group A, p = 0.001 for group B; pain: p < 0.01 for group A, p < 0.01 for group B). There was no statistically significant between-group difference regarding mechanosensitivity (p = 0.07) or pain intensity (p = 0.838). Conclusions. The addition of tensioning NM to traditional physical therapy had no significant benefits, although both groups showed decreased post-treatment mechanosensitivity and pain intensity.
New approach to uniformly quasi circular motion of quasi velocity biharmonic magnetic particles in the Heisenberg space

In this paper, we define concept of the uniformly quasi circular motion (UQCM) with biharmonicity condition in the Heisenberg space. That is, we aim to define a new class of UQCM in the three‐dimensional Heisenberg space. We further improve an alternative method to find uniformly quasi circular potential electric energy of biharmonic velocity magnetic particles in the Heisenberg space. We also give the relationships between physical and geometrical characterizations of uniformly quasi circular potential electric energy. Finally, we illustrate important figures for uniformly quasi circular potential electric energy with respect to its electric field in the radial direction.
Management of Ralstonia solanacearum (potato wilt disease) virulence by using bioactive compounds

Potato is an important vegetable crop of Bangladesh which is facing challenges worldwide due to a quarantine pathogen, Ralstonia solanacearum. It is a very successful bacterial pathogen against most of the traditional management practices. Suspension of ten bioactive compounds viz. propolis, honey, turmeric powder+oil, turmeric powder, magnesium chloride, boiled rice fluid, boiled rice fluid+iodine, sun dried cow dung powder, honey+iodine and sodium bicarbonate were evaluated and compared with control (sterile water), commercial bactericide (Krosin AG) and farmers practice (stable bleaching powder). In vitro assessment was done by comparing the inhibition zones produced on TZC (tetrazolium chloride) solid medium in disc diffusion method. All of those compounds produced larger inhibition zones as compared to control which indicated the effectiveness of the test compounds against the bacteria. To screen out the performances of those compounds in vivo, potato seedlings were inoculated in sterilized soil by soil soak method. Later, mature plants were inoculated in unsterilized soil to find the better resulting compound(s) in field soil condition against the disease. Finally, suspension of cow dung (@25%), propolis (@ 6mg/ml) and turmeric powder (@25%) were selected for trial as soil and seed treatment against the pathogen. It was found that, cow dung reduced 28.89% disease severity index which was followed by 26.67% in propolis and 22.22% in turmeric powder as compared to control (84.44%) in artificially inoculated potato plants against R. solanacearum.

Disentangling Subject and Anacoluthon NPs in Topic: A Cognitive Grammar and Gestalt Psychology based approach

In this paper we analyze NPs in Topic which can be either the subject of the verb in Comment, or autonomous items usually called anacolutha (LI; THOMPSON, 1976). It explores how these different NPs are mapped according to spontaneous speech data. Departing from Langacker's proposal (2001), in which the Topic and the subject act as trajectors of different scopes, it is argued that such a concept is adequate to the empirical data, since it allows the possibility of co-occurrence and intertwining of both categories in speech. In addition, we also investigated the difference in the cognitive processing of subject and anacoluthon NPs in Topic building upon the concepts of baseline and elaboration (LANGACKER, 2016). Through this framework, it is possible to conceive that the Topic-Comment is activated serially giving rise to the formation of structural layers in the cases that the NP in Topic is the subject of the verb in the Comment. Or it can be the result of a cumulative access via summation, if the NP is an anacoluthon. As the concepts of subject and Topic in the approach of Cognitive Grammar derive, in part, from the Gestalt psychology notions of Figure and Ground, the anacoluthon in Topic can be referred to as the Figure and the illocutionary force of the Comment would be the Ground. The only difference in relation to the visual elements is that, since they displaces through the space axis, the Figure and the Ground can be inverted depending on where the focus of attention is turned. However, as the speech is unfolded along the time axis, reversion is not possible, in such a way that an Anacoluthon in Topic will always be the Figure and the Comment will always be the Ground. In addition, the dependency relation of the Figure regarding the Ground explains the reason for a Topic cannot occur without a Comment.
Suicidality and Exposure to School-Based Violence Among a Nationally Representative Sample of Asian American and Pacific Islander Adolescents

Abstract This study sought to contribute to the limited research on the prevalence of suicidal behaviors and exposure to school-based violence among Asian American and Pacific Islander (AAPI) adolescents. It also examined the relationship between engagement in suicidal behaviors and exposure to school-based violence among AAPI adolescents. Results from a national sample of 14,765 adolescents via the Centers for Disease Control and Prevention’s most recent Youth Risk Behavior Surveillance System data demonstrated that the prevalence of AAPI adolescents engaging in suicidal behaviors and experiencing school-based violence is comparable to that of non-AAPI adolescents. A significant correlation between exposure to school-based violence and four specific suicidal behaviors was observed among this sample of AAPI adolescents. Across the entire sample, adolescents who reported engaging in any suicidal behavior experienced significantly higher levels of school-based violence. Implications for promoting and implementing trauma-informed approaches in schools along with integrating existing mental health practices with school-based violence prevention efforts tailored to the needs of AAPI adolescents are discussed. Impact Statement Results from a national sample of nearly 15,000 adolescents demonstrated that the prevalence of Asian American and Pacific Islander (AAPI) adolescents engaging in suicidal behaviors and experiencing school-based violence is comparable to that of non-AAPI adolescents. Across the entire sample, adolescents who reported engaging in any suicidal behavior experienced significantly higher levels of school-based violence. These findings highlight the critical importance of promoting and implementing trauma-informed approaches in schools along with integrating existing mental health practices with school-based violence prevention efforts tailored to the needs of AAPI adolescents.
Role of Diffusion Tensor Imaging and Motor Functional MRI in Preoperative Assessment of Brain Tumors

Diffusion tensor imaging is a non-invasive magnetic resonance imaging technique that describe the orientation and location of white matter tracts in vivo, it guides the surgeon regarding the relationship of the intra-axial tumor to adjacent white matter tracts in different planes. Routine pre-surgical FMRI allows for assessment of the relationship between brain tumor and motor cortex to facilitate function-preserving surgery and reduce postoperative morbidity. The purpose of this study is to evaluate role of diffusion tensor magnetic resonance imaging, fiber tractography and motor functional MRI in assessment of white matter tracts affected by the tumor, and to utilize this information in guiding surgeons. Fifty patients with different types of brain tumors were enrolled in this study. Fiber tracts involvement were classified into four categories (edema, displacement, infiltration and disruption), comparison between benign and malignant tumors groups as regards to the patterns of fiber tracts involvement were done. The prevalence of edema and displacement was higher among the benign group while prevalence of infiltration and disruption was higher among the malignant group. Localization of the primary motor hand area with functional MRI was done, The relation of it to the tumor was measured. Treatment plans before and after DTI & functional MR imaging differed in 35 patients as regard to surgical approach and in 17 patients as regard to modification of extent of resection with significant relation. Diffusion tensor imaging DTI represents recent important progress in the field of diagnostic imaging. It is the only technique that is able to visualize in vivo white-matter tracts so that it is of great help in pre-operative neurosurgical planning.
Reliability evaluation method of LED lighting matrix considering degradation and catastrophic failure

Aiming at the current situation of degradation and catastrophic failure of weaponry, a reliability modelling method considering performance degradation (lumen degradation) and catastrophic failure (nonluminous) is proposed with LED lighting matrix as the research object. First, for the degradation of lumen, the failure mechanism analysis is carried out, the thermal resistance model of lighting matrix and radiator is established, and the overall model of the degradation of the LED lighting matrix is realized. For the catastrophic failure, based on the uncertainty of the logic relationship of catastrophic failure of lighting matrix and the polymorphism of individual fault events, the method of combining fault tree and Bayesian network is used to realize the analysis of failure evolution and reliability modelling. Finally, the validity of the proposed method is verified with a case study.
A Dual-Band Modified Franklin mm-Wave Antenna for 5G Wireless Applications

Franklin array antennas are considered as one of the most competitive candidates for millimeter-wave (mmW) 5G applications due to their compact size, simple geometry and high gain. This paper describes a microstrip Franklin antenna array for fifth generation (5G) wireless applications. The proposed modified Franklin array is based on a collinear array structure with the objective of achieving broad bandwidth, high directivity, and dual-band operation at 22.7 and 34.9 GHz. The designed antenna consists of a 3 × 3 array patch element as the radiating part and a 3 × 3 slotted ground plane operating at a multiband resonance in the mmW range. The dimensions of the patch antennas are designed based on λ/2 of the second resonant frequency. The designed antenna shows dual band operation with a total impedance bandwidth ranging from 21.5 to 24.3 GHz (fractional bandwidth of 12.2%) at the first band and from 33.9 to 36 GHz (fractional bandwidth of 6%) at the second band in simulation. In measurement, the impedance bandwidth ranges from 21.5 to 24.5 GHz (fractional bandwidth of 13%) at the first band and from 34.3 to 36.2 GHz (fractional bandwidth of 5.3%) at the second band, respectively. The performance of the antenna is analyzed by parametric analysis by modifying various parameters of the antenna. All the necessary simulations are carried out using HFSS v.14. 0.

Processing and Representation of Multispectral Images Using Deep Learning Techniques

This thesis has implemented innovative techniques in the field of computer vision using visible and near-infrared spectrum images, applying deep learning through convolutional networks, especially GANs' architectures, which are specialists in generating information and also includes meta techniques -learning to tackle the problem of determining the similarity of images of a different spectrum. In this research, with this type of convolutional networks, different supervised and unsupervised techniques have been created to solve challenging problems, like detect the similarity of patches of different spectra (visible-infrared), colorized images of the near-infrared spectrum, estimation of vegetation index (NDVI) and the haze removal present on RGB images using NIR images. For all these techniques different variants of the GAN's networks, such as standard, conditional, stacked, and cyclic have been used. Also, a metric-based meta-learning approach has been implemented. It should be mentioned that together with the implementation of adversarial network models, the use of multiple loss functions has been proposed to improve the generalization and increase the effectiveness of the models. The experiments were performed with paired and unpaired images, given the different supervised and unsupervised architectures implemented, respectively. The experimental results obtained in each of the approaches implemented in the doctoral work compared with the techniques of the state of the art were shown to be more effective.
A preliminary evaluation of the use of treated mill effluent in hydrosulphite and peroxide bleaching of TMP: Initial results show it has little effect on brightness or chemical use

Nous avons effectue des etudes de laboratoire pour etudier la possibilite d'utiliser des effluents d'usine traites biologiquement en remplacement de l'eau froide dans le blanchiment des pâtes mecaniques a l'hydrosulfite et au peroxyde d'hydrogene. Dans le blanchiment a l'hydrosulfite, la substitution complete de l'eau froide par les effluents traites n'a eu aucun effet sur l'augmentation du degre de blancheur. Par ailleurs, dans le blanchiment au peroxyde d'hydrogene a faible et moyenne consistances, les resultats ont laisse voir des effets nuls sinon faiblement nuisibles sur le degre de blancheur et la consommation de peroxyde, tout specialement a des charges elevees de NaOH.
