Authors: Kadanali S. , Küçüközkan T. , Zor N. , Kumtepe Y. 
Published: July 2002

AbstractObjective: To compare the efficacy and safety of intravaginal and oral misoprostol vs. oxytocin/prostaglandin E2 (PGE2) gel for third trimester labor induction. Methods: Two hundred twenty‐four pregnant women were randomized to induction of labor either with misoprostol or oxytocin and PGE2 gel. Patients in the misoprostol group (n = 112) received 100 μg intravaginal misoprostol followed by 100 μg p.o. every 2 h. The oxytocin/PGE2 group consisted of 112 patients who underwent PGE2 cervical instillation 6 h before continuous oxytocin infusion. The perinatal, intrapartum and neonatal characteristics of both groups were determined. Results: Induction to active phase of labor was successfully achieved in 96 women (85.7%) in the misoprostol group vs. 86 women (76.8%) in the oxytocin/PGE2 group, but the drug initiation‐delivery interval was significantly shorter in the misoprostol group (9.2 ± 2.4 h) than in the oxytocin/PGE2 group (15.2 ± 3.2 h, P < 0.001). The incidence of adverse intrapartum outcomes was similar for both methods. Intravaginal misoprostol 100 μg followed by a single oral dose of 100 μg misoprostol safely produced labor and a vaginal delivery in 70% of patients. More than three tablets were required in only 10% of patients. There was a higher prevalence of cesarean section for failed induction in the oxytocin/PGE2 group than in the misoprostol group (13.4 vs. 6.3%, P < 0.001). The neonatal outcomes of both groups were also similar. Conclusion: Misoprostol is significantly more effective for labor induction than oxytocin/PGE2 gel. The maternal intrapartum and neonatal outcomes were the same for both induction regimens. From a clinical and perinatal perspective, misoprostol is an acceptable choice for labor induction.

Published: July 2002

AbstractObjective: To determine the relationship between maternal perception of sound‐provoked fetal movement in the early intrapartum period and perinatal outcome. Method: 739 singleton pregnant women of at least 32 weeks gestation who were admitted to the labor ward, underwent the maternal perception of sound‐provoked fetal movement test. All were in the latent phase of labor with singleton cephalic presentation. The result of maternal perception of sound‐provoked fetal movement was compared with the perinatal outcome using sensitivity, specificity, negative predictive value, positive predictive value and accuracy. Results: When 739 pregnant women were compared to the perinatal outcome, maternal perception of sound‐provoked fetal movement had sensitivity 100%, specificity 98.9%, positive predictive value 15.1%, negative predictive value 100%, and accuracy 90.1%. Conclusion: The finding suggested the usefulness of maternal perception of sound‐provoked fetal movement as an effective screening test to identify fetuses at risk in the early intrapartum period because of its high sensitivity and specificity. This is a simple and inexpensive test for evaluating fetal well‐being in a primary health care setting.

AbstractWe have recently described a modified model of progressive rapid ventricular pacing‐induced heart failure which evolves over a period of 38 days. To further characterize left ventricular remodeling during the progression of heart failure, we assessed left ventricular geometry, wall stress, and atrial natriuretic peptide (ANP) gene expression and protein content during control conditions, asymptomatic left ventricular dysfunction, and overt congestive heart failure (CHF). Although asymptomatic left ventricular dysfunction was characterized by a significant increase in systolic and diastolic left ventricular dimension (+30% and +6%, respectively, P<0.05 each) and a marked increase in left ventricular systolic wall stress (+68%, P<0.01), left ventricular ANP gene expression was unchanged as compared to control. In contrast, strong left ventricular ANP gene expression (+449%, P<0.05) was observed during overt CHF in the absence of further significant increases in left ventricular systolic wall stress. The onset of strong left ventricular ANP gene expression was associated with increased ANP content (+88%, P<0.05) and left ventricular mass index (+13%, P<0.05). In contrast, left atrial ANP gene expression and left ventricular diastolic wall stress increased progressively during asymptomatic left ventricular dysfunction (+39%, P=n.s. and +131%, P<0.01) and overt CHF (+76% and +336% vs. control, P<0.01 each). Progressive rapid ventricular pacing is associated with the induction of left ventricular ANP gene expression and protein synthesis exclusively during overt CHF. The current studies provide new insight into the temporal pattern of ANP‐activation and the disparity between left ventricular systolic wall stress and ANP‐activation in a large animal model of progressive CHF.

AbstractSonodynamic therapy (SDT) is considered to be a potential treatment for various diseases including cancers and bacterial infections due to its deep penetration ability and biosafety, but its SDT efficiency is limited by the hypoxia environment of deep tissues. This study proposes creating a potential solution, sonothermal therapy, by developing the ultrasonic interfacial engineering of metal–red phosphorus (RP), which has an obviously improved sonothermal ability of more than 20 °C elevation under 25 min of continuous ultrasound (US) excitation as compared to metal alone. The underlying mechanism is that the mechanical energy of the US activates the motion of the interfacial electrons. US‐induced electron motion in the RP can efficiently transfer the US energy into phonons in the forms of heat and lattice vibrations, resulting in a stronger US absorption of metal–RP. Unlike the nonspecific heating of the cavitation effect induced by US, titanium–RP can be heated in situ when the US penetrates through 2.5 cm of pork tissue. In addition, through a sonothermal treatment in vivo, bone infection induced by multidrug‐resistant Staphylococcus aureus (MRSA) is successfully eliminated in under 20 min of US without tissue damage. This work provides a new strategy for combating MRSA by strong sonothermal therapy through US interfacial engineering.

Nanofriction characteristics of h-BN with electric field induced electrostatic interaction
Authors: Yu Kemeng , Zou Kun , Lang Haojie , Peng Yitian 
Published: December 2020

AbstractThe nanofriction properties of hexagonal boron nitride (h-BN) are vital for its application as a substrate for graphene devices and solid lubricants in micro- and nano-electromechanical devices. In this work, the nanofriction characteristics of h-BN on Si/SiO2 substrates with a bias voltage are explored using a conductive atomic force microscopy (AFM) tip sliding on the h-BN surface under different substrate bias voltages. The results show that the nanofriction on h-BN increases with an increase in the applied bias difference (Vt−s) between the conductive tip and the substrate. The nanofriction under negative Vt−s is larger than that under positive Vt−s. The variation in nanofriction is relevant to the electrostatic interaction caused by the charging effect. The electrostatic force between opposite charges localized on the conductive tip and at the SiO2/Si interface increases with an increase in Vt−s. Owing to the characteristics of p-type silicon, a positive Vt−s will first cause depletion of majority carriers, which results in a difference of nanofriction under positive and negative Vt−s. Our findings provide an approach for manipulating the nanofriction of 2D insulating material surfaces through an applied electric field, and are helpful for designing a substrate for graphene devices.
Generalized laws of refraction and reflection at interfaces between different photonic artificial gauge fields

Published: December 2020

AbstractArtificial gauge fields the control over the dynamics of uncharged particles by engineering the potential landscape such that the particles behave as if effective external fields are acting on them. Recent years have witnessed a growing interest in artificial gauge fields generated either by the geometry or by time-dependent modulation, as they have been enablers of topological phenomena and synthetic dimensions in many physical settings, e.g., photonics, cold atoms, and acoustic waves. Here, we formulate and experimentally demonstrate the generalized laws of refraction and reflection at an interface between two regions with different artificial gauge fields. We use the symmetries in the system to obtain the generalized Snell law for such a gauge interface and solve for reflection and transmission. We identify total internal reflection (TIR) and complete transmission and demonstrate the concept in experiments. In addition, we calculate the artificial magnetic flux at the interface of two regions with different artificial gauge fields and present a method to concatenate several gauge interfaces. As an example, we propose a scheme to make a gauge imaging system—a device that can reconstruct (image) the shape of an arbitrary wavepacket launched from a certain position to a predesigned location.

Abstract
Aim of the study Sepsis has well-documented inflammatory effects on cardiovascular and blood cells. This study is designed to investigate potential anti-inflammatory effects of metformin on cardiac and blood cells 12 and 24 h following cecal ligation and puncture (CLP)-induced sepsis.
Methods For the purpose of this study, 36 male Wistar rats were divided into six groups: two groups underwent CLP, two groups underwent CLP and received metformin, and two groups only received sham operations. 12 h later, 18 rats (half of rats in each of the three aforementioned groups) were sacrificed and cardiac and blood cells were harvested. Subsequently, 12 h later, the rest of the rats were euthanatized. In all harvested blood and cardiac cells, oxidative stress indicators, antioxidant properties, count of blood cells, neutrophil infiltration, percentage of weight loss and pathological assessment were conducted.
Results In our experiment, metformin elevated antioxidant levels, improved function of blood cells and percentage of weight loss. Moreover, in the groups which received metformin, oxidative stress and neutrophil infiltration markers were decreased significantly. Moreover, pathological investigations of cardiac cell injury were reduced in the metformin group.
Conclusions Our findings suggest that in CLP induced sepsis model, metformin can improve the function of blood and cardiac cells through alleviating inflammation, improvement of anti-inflammation properties, and enhancement of blood profile, and all these effects are more pronounced after 24 h in comparison with 12 h after induction of sepsis.
The final particle like in Northern
English
Authors: Hancil Sylvie 
Published: December 2020

Abstract
The study of the use of quotative
like has been the object of increasing interest
from linguists over the last two decades (see Romaine & Lange 1991; Buchstaller 2002, among
others) as it is a recent and global phenomenon. By contrast, final
like is more established and restricted to
varieties in the British Isles. It is possible to further this
research by relying on the NECTE corpus (Newcastle Electronic Corpus
of Tyneside English), since in Northern English, especially in
Newcastle English, the particle is developing a new function of
discourse marker; it is associated with semantic values of anaphor,
cataphor, intensifier and filler. The final position of the marker
can be held responsible for the development of a significant number
of interactional forces between speaker and co-speaker, which reveal
the discursive strategy of the speaker towards the co-speaker (Pomerantz 1984). The study
will be complemented by the analysis of the final particle
like in the light of Brown & Levinson (1987)’s politeness
theory and it will be shown that its use is a combination of
negative and positive politeness within the utterance.

Published: December 2020

Abstract
Multifunctionality of Carbon-Based Nano Materials, Graphene in particular is gaining more relevance in their diversified applications. Today, the fabrication of luminescent graphene materials is significant for the field of bioimaging of healthy and malignant cells due to their biocompatible tunable fluorescence. In this aspect there is a need for a simple, energy efficient process for the introduction of hetero atoms of Oxygen and Sulphur into the graphene structure to explore the enhancement of fluorescence. The present study aims at the optimization of processing temperature and other experimental parameters for doping hetero atoms of Oxygen and Sulphur in the graphene structure for tuning their luminescence properties. The method involved hydrothermal carbonization of simple precursor of glucose at lower temperatures of 180°C and 220°C and alkaline pH followed by the analytical characterization of the product samples. The introduction of hetero atoms, the presence of sp2 Carbon, band gap energy, microstructure along with layer structureswere ascertained in the as-synthesized graphene samples. The influence of processing temperature, oxygen functionality and defect structures upon emission wavelength range of graphene in the visible region was well correlated. Ultimately, the study provided the fundamental aspects of fabricating graphene structures suitable for tunable fluorescence of graphene aimed at bio imaging technique.

Abstract
In recent times, the importance of nanostructure of metal oxide semiconductor (MOS) as a gas sensing material is rising tremendously. Among various metal oxide semiconductors ZnO has potential to be used as a sensor for several toxic gases. In this work, we investigated the influence of Fe doping into ZnO to detect various concentrations of ethanol vapour. Pristine and Fe doped ZnO (Fe-ZnO) films were deposited on glass substrates using a spin coating technique wherein the concentration of Fe can be easily controlled. The crystallite size and surface morphology of ZnO samples were characterized by XRD, SEM and EDX techniques. The sensor performance in terms of gas response (R) of ZnO and Fe-ZnO gas sensors towards ethanol vapour were measured in the 100 to 300°C temperature range using DC electrical resistance. Fe doped ZnO samples showed enhancement in gas response due to increase in specific surface area originated from reducing grain size after doping. The 2% Fe-ZnO sample showed the good response of 40.9 for 400 ppm of ethanol vapour exposure at 260°C. This was found to be better than reported values for ZnO prepared by different methods.

Abstract
Increased machine efficiency, increased speeds of working bodies, reduced material consumption, increased load, the need to ensure reliable operation of equipment and safe working conditions are the main factors, that determine attention to vibration protection problems. This constitutes the current trend in the modern dynamics of machines. In this work, we propose a method for the dynamic synthesis of dynamic vibration dampers of a viscoelastic mechanical system having the structure of several (two) bodies elastically attached to the object. The aim of the work is to develop methods of mathematical and computer modeling of the processes of dynamics of active and passive vibration protection systems, as well as to increase the efficiency of using passive and active vibration protection of objects. When developing a system for protecting radio-electronic devices (RED) at resonant frequencies, elements of the theory of automatic control and mathematical modeling were used. An algorithm for generating feedback signals for the information-measuring system for active control of vibration-protective radio-electronic devices is proposed. A method is developed for numerically - analytical study of oscillatory processes of nonlinear mechanical systems consisting of spatial rigid bodies interconnected by massless viscoelastic elements.

Abstract
Researches show that almost seven million people worldwide are dying due to air pollution every year. Data given by World Health Organization observed that 9 out of 10 people breathe the air that contains significant proportions of poisons. Monitoring helps in evaluating the degree of contamination corresponding to the surrounding air quality benchmarks. In this work, a IoT based air quality monitoring system is developed using Raspberry Pi Internet of Things (IoT) platform. A MQ135 sensor is used to detect gases like CO, Ammonia, Smoke, Alcohol, etc., and the corresponding data is processed using moving average method to avoid the redundant data samples, stored in a database to do further analysis and future predictions of the air pollutants. This will help future generations to take precautions and stay safe.

Abstract
Multi-user detection (MUD) is a popular method in wireless communication systems to enhance efficiency by together processing the signals received from all users. The complexity of MUD has been a great problem in practical scenario. Wiener (optimum) filter yields best estimate of the input signal from noisy observations. In this paper, using Wiener filtering, a less complex and robust MUD strategy is introduced in a new multiple access scheme called interleave-division multiple-access (IDMA) which supports MUD in a simple way. The proposed IDMA system helps in achieving lower bit error rate and manages multiple number of users easily when compared to other multiple access schemes.

Abstract
It is very common to miss certain words when writing while listening to others. A similar problem can arise when typing on the computer. The automatic generation of missed words shall very much helpful for users by suggesting the required words. In this research work, missed words of the Assamese sentences are generated, at present, there is no such tool/method exists which can provide or generate the missed words in an Assamese sentence. N-gram based models like bigram and trigram are used to generate missed words. Using the bigram and trigram models a rank is calculated for each possible suggested words and the suggested word list is sorted according to this rank value in decreasing order. Finally, these suggested words can be used to fill the place of the missed Assamese words. Different levels of experiments are carried out and the present proposed system can correct the missed words at an accuracy ranging from 58% to 66%. The proposed model can precisely generate accurate five relevant suggestions for a sentence containing an average of six words with two missed words separated by three words.
