In vitro bioactivity of AH plus with the addition of nano-magnesium hydroxide

Background AH Plus (AH) has been widely used as a root canal sealer in the endodontic field due to its superior physicochemical properties. However, clinical application of AH is limited due to its weak bioactivity. Methods In this study, we have developed an AH cement containing nano-magnesium hydroxide (NMH) as an additive to enhance the bioactivity of AH. The NMH can neutralize pH and facilitate bone formation. The objective of this study was to evaluate the effects of NMH and modified AH on osteoblasts behavior in vitro. The CCK-8, alkaline phosphatase (ALP) staining, and real-time polymerase chain reaction (PCR) assays were used to assess the proliferation and differentiation of MC3T3-E1 cells, respectively. The adhesion and spreading of MC3T3-E1 cells were investigated in vitro by scanning electron microscopy (SEM). Meanwhile, the flow and magnesium ion release of the modified AH was also concerned. Results In vitro cell assays further showed that the addition of NMH into AH cement, which was denoted as modified AH (especially AH+3%NMH), could effectively improve the proliferation and osteogenic differentiation of MC3T3-E1 cells. Conclusions Taken all together, we believe that the modified AH samples (especially AH+3%NMH) have outstanding biocompatibility and osteogenic properties and may have great potential in endodontic field.
The Linkages of the Role of Human Capital and Knowledge Management on Innovation: According to a Literature Studies

The advancement in the field of information technology and the increasing of competitive competition havemade many companies shift from conventional business by relying on labor (labor based business) into knowledge based business of which main characteristic is knowledge. Knowledgebased business is a business that is run with more use of intellectual capital. In order to be able to survive in the business environment, organizations carry out various methods such as creating product innovation, expanding markets, improving service quality, improving production process, improving organizational system, and doing cost saving. Organizational strategies are made and created in order to survive in the rapid changes of environment, and organizational strategies must be able to create competitive advantage (Kusuma, 2005). Banking sector is a business sector that utilizes intellectual capital quite intensively. Banking in Indonesia consists of sharia banking and conventional banking which in principle are high technology and high servicecompanies, also driven by the development of information technology and knowledge in their operational activities so that it has triggered the need for the banks to develop intellectual capital in conducting their business.Based on the above-mentioned matters, it is necessary to conducta study in the banking sector in order to see how far the role of human capital is,as part of intellectual capital and knowledge management,in innovation in banking companies in Indonesia. After discovering the impact, in the following year a further study will be carried out to see how the innovation in the companies would affect the companies’ competitive advantage and what the impact is on company performance.
ON COSET DECOMPOSITIONS OF THE COMPLEX REFLECTION GROUPS G ( M , P , R )

We study the decomposition of the imprimitive complex reflection group G(m, p, r) into right coset, where m, p, r are positive integers, and p divides m. By use of the software GAP to compute some special cases when m, p, r are small integers, we deduce a set of complete right coset representatives of the parabolic subgroup G(m, p, r-1) in the group G(m, p, r) for general cases, which lays a foundation for further study the distinguished right coset representatives of G(m, p, r-1) in G(m, p, r).
Room Acoustics and Speech Perception

The acoustic speech signal received by a listener is a function of the source, distance, early reverberation, late reverberation, and noise. Specifically, it depends on the Speech Audibility Index, which is defined, here, as the proportion of the combined direct speech and early reverberation (also known as early reflections) whose level is above that of the combined noise and late reverberation. Speech Audibility Index rises from 0 to 100% as the effective signal-to-noise ratio rises from -15 to +15 dB. Both reverberation and ambient noise need to be low in order to maintain Speech Audibility Index at an optimal level. Speech Audibility Index can be used to predict various measures of speech perception, but the results are highly dependent on the complexity of the language and the characteristics of the listener. Conditions that are tolerable for normally hearing adults in casual conversation can be difficult for adults and children in learning situations, and intolerable for persons with deficits of hearing, language, attention or processing. Sound-field amplification can improve Speech Audibility Index for all listeners in a noisy room. It offers less benefit when the primary problem is reverberation and, if improperly installed, can make the reverberation problem worse. There is no good substitute for reverberation control. Audiologists have an important contribution to make in the identification and resolution of continuing inadequacies of classroom acoustics. Introduction Room acoustics have a major effect on the transmission of speech sounds from talker to listener. Four principal factors are involved: distance, early reverberation, late reverberation, and noise. The present paper outlines the effects of these factors on the reception and perception of speech. The initial speech signal Before examining what happens to speech in a room, it is important to define the original acoustic signal. i) Long-term average level For present purposes, I will consider the original acoustic signal to be that measured at 1 foot from the lips. At this distance, the long-term speech level of a typical talker, averaged over 10 or 20 seconds, is around 70 dB SPL. It is important to remember, however, that this value is summed across frequency and averaged over time. ii) Long-term average spectrum The heavy line in Figure 1 shows the long-term level of a 12 second speech sample measured in 1/3-octave bands. This is the Long-TermAverage Speech Spectrum or LTASS. The level is highest in the lowfrequency bands, and falls at the rate of around 6 dB per octave at frequencies above 500 Hz (see, also, Cox and Moore, 1988; Boothroyd, Erickson, and Medwetsky, 1994). It is a characteristic of the acoustic Room Acoustics. Boothroyd, 2002. Page 3 of 18 Frequency in Hz 125 250 50
k-TVT: a flexible and effective method for early depression detection

The increasing use of social media allows the extraction of valuable information to early prevent some risks. Such is the case of the use of blogs to early detect people with signs of depression. In order to address this problem, we describe k -temporal variation of terms ( k -TVT), a method which uses the variation of vocabulary along the different time steps as concept space to represent the documents. An interesting particularity of this approach is the possibility of setting a parameter (the k value) depending on the urgency (earliness) level required to detect the risky (depressed) cases. Results on the early detection of depression data set from eRisk 2017 seem to confirm the robustness of k -TVT for different urgency levels using SVM as classifier. Besides, some recent results on an extension of this collection would confirm the effectiveness of k -TVT as one of the state-of-the-art methods for early depression detection.

The aim of this manuscript is a review of relevant studies concerning rotavirus gastroenteritis-associated hepatitis.
Analysis of relation types in semantic network used for text classiﬁcation

—Contemporary information systems contain lots of textual information. One of important kinds of textual information processing is text classiﬁcation. Semantic network is a model which can be used to resolve different tasks including text classiﬁcation. There are other models which can resolve the same task, and some of them show relatively good results, but using semantic networks has such advantages as human readability and analyzing actual semantic relations between words. Semantic networks have different set of relation types depending on the network purpose. This article is devoted to looking for a set of relation types to be leveraged in semantic network created for text classiﬁcation. The analysis is performed by generating semantic networks for Russian-language texts leveraging different sets of relation types. Generated networks are used for text classiﬁcation. Texts were taken from books on several technical disciplines. Proposed algorithms can be used to perform text classiﬁcation when performing such tasks as dividing electronic messages on categories, spam ﬁltering, text topic recognition and other.
Appl. Entomol. Zool. 39 (2): 243–248 (2004)

The development and reproduction of the braconid wasp, Lysiphlebus japonicus Ashmead, parasitizing either symbiotic or aposymbiotic aphids, were investigated. In order to obtain aposymbiotic aphids, the black bean aphid, Aphis craccivora Koch, was fed at birth with Vicia faba dipped in 200 mg/ml rifampicin. Transmission electron microscopy revealed that the intracellular symbiotic bacteria (Buchnera) began to degenerate 2 days after the antibiotic treatment. Bacteria-free aposymbiotic aphids exhibited a reduced growth rate, adult size and reproduction rate. The development and reproduction of the parasitoids were clearly affected by the rifampicin treatment of the aphid host. The larval size and the growth rate of the parasitoids were reduced, and the emergence rate and the body weight of the wasps decreased by 13% and 54%, respectively. The number of progeny produced by the wasps that emerged from aposymbiotic aphids decreased by 25%. Possible factors involved in the effects of aposymbiosis on the parasitoids are discussed.
The Prevalence of Glaucoma among Pseudoexfoliation Syndrome Patients

Introduction: Pseudoexfoliation syndrome is a recognized risk factor for developing glaucoma, cataract and lens dislocation. Pseudoexfoliation syndrome is also associated with increased risk of complications during cataract surgery due to poor mydriasis and zonular weakness. Objective: The aim is to find out the prevalence of glaucoma in Pseudoexfoliation syndrome patients attended to Shaheed Doctor Aso hospital, Sulaimaniya city, Kurdistan region of Iraq and Azadi Teaching Hospital, Kirkuk city Iraq. Patients and Methods: This cross sectional study encompassed 378 patients (756 eyes) with whom the pseudoexfoliation syndrome was detected as an incidental finding aged 50 years or older. A detailed evaluation including general and ophthalmic history, slit lamp biomicroscopy, intraocular pressure measurement (TOPCON computerized tonometer CT-80 and Goldmann Applanation tonometer), gonioscopy (Goldmann three mirrors goniolens) and dilated eye examination were performed. Oral informed consent was obtained from all participants. Results: Out of the 378 patients who had pseudoexfoliation syndrome, 58 (15.3%) were diagnosed with pseudoexfoliation glaucoma and 34 patients (9%) with ocular hypertension. In the glaucomatous patients, men to women ratio was 2:1, this was statistically significant (p = 0.001). Most of patients in the age group (70-79) years of age, represent 23.3%. Bilateral Pseudoexfoliation syndrome was associated more with pseudoexfoliation glaucoma (58.6%), while unilateral pseudoexfoliation syndrome was associated more with ocular hypertension (64.7%). The Kurdish race patients expressed the highest prevalence of pseudoexfoliation glaucoma and ocular hypertension (31.5%) followed by the Arabic race (20%) and lastly the Turkmen (16%). Conclusion: Pseudoexfoliation syndrome showed to be a significant glaucoma risk factor locally, with a prevalence of (15.3%), and if we added the Ocular hypertension (9%), it will be (24.3%). Recommendation: Patients with Pseudoexfoliation syndrome should be informed and examined at least annually as the risk may be present throughout their life and increasing with age.
Phcog Rev.: Plant Review Andrographis paniculata (Kalmegh): A Review

Andrographis paniculata (Burm.f.) Nees (Acanthaceae) is a medicinal plant traditionally used for the treatment of cold, fever, laryngitis and several infectious diseases ranging from malaria to dysentery and diarrhea in China, India and other south east Asian countries. The plant is claimed to possess immunological, antibacterial, antiinflammatory, antithrombotic and hepatoprotective properties. In Malaysia, the plant is used in folk medicines to treat diabetes and hypertension. The contents of diterpenoids like andrographolide, neoandrographolide and dehydroandrographolide are the chief criteria for monitoring the quality of A. paniculata. Andrographolide, though found in all plant parts, is most concentrated in the leaves. It is a diterpene containing a γlactone ring connected to a decalin ring system via an unsaturated C-2 moiety. It has multiple pharmacological properties such as protozoacidal, antihepatotoxic, anti-HIV, anticancer, antitumor, hypoglycemic and hypotensive activities. Andrographolide is an interesting pharmacophore with anticancer and immunomodulatory activities and hence has the potential to be developed as an anticancer chemotherapeutic agent as well. In this review, we have explored the various dimensions of the Andrographis paniculata plant and compiled its vast pharmacological applications to comprehend and synthesize the subject of its potential image of multipurpose medicinal agent. The plant is widely cultivated to large regions of the world and its importance as a medicinal plant is growing up substantially with increasing and stronger reports in support of its multifarious therapeutic uses.
Gender Bias and Intergenerational Educational Mobility: Theory and Evidence from China and India

This paper incorporates gender bias against girls in the family, school and labor market in a model of intergenerational persistence in schooling where parents self-finance children's education because of credit market imperfections. Parents may underestimate a girl's ability, expect lower returns, and assign lower weights to their welfare (“pure son preference”). The model delivers the widely used linear conditional expectation function under constant returns and separability but generates an irrelevance result: parental bias does not affect relative mobility. With diminishing returns and complementarity, the conditional expectation function can be concave or convex, and parental bias affects both relative and absolute mobility. This paper tests these predictions in India and China using data not subject to coresidency bias. The evidence rejects the linear conditional expectation function in rural and urban India in favor of a concave relation. Girls in India face lower mobility irrespective of location when born to fathers with low schooling, but the gender gap closes when the father is college educated. In China, the conditional expectation function is convex for sons in urban areas, but linear in all other cases. The convexity supports the complementarity hypothesis of Becker et al. (2018) for the urban sons and leads to gender divergence in relative mobility for the children of highly educated fathers. In urban China, and urban and rural India, the mechanisms are underestimation of the ability of girls and unfavorable school environment. There is some evidence of pure son preference in rural India. The girls in rural China do not face bias in financial investment by parents, but they still face lower mobility when born to uneducated parents. Gender barriers in rural schools seem to be the primary mechanism.

Improved Performance of a Rectenna Array for Wireless Low Power Transportation

The study presented here focuses on the design of a simple and compact rectenna (rectifying antenna) to enhance the performance at a relatively low power levels. The rectifier is realized with a single schottky diode SMS-7630 in reverse topology and optimised at the fundamental frequency f 0 = 2.45 GHz. Although a single narrow-band design is conductive enough to achieve high efficiency, we know that the amount of the DC output power is limited. To overcome this issue, one solution would be a rectenna array designed for collecting more HF power to produce more DC power. The opportunity in this study would be to increase performances of a ground receiving rectenna, and more precisely for those located on the edges of the array where the RF power density are low. To estimate the DC power, we started with the study of a 2x5 planar array of small metamaterial-inspired antennas. Each antenna incorporates its own rectifier to collect DC power and is assembled in series manner. The size of the overall rectenna array is 110*90mm 2. Finally, our most recent studies show an increase of the collected DC voltage with the presence of a reflector at a distance of 3λ/4 to the back of the rectenna array.
K-means algorithm with level set for brain tumor segmentation

Brain is a complicated structure consisting of millions of millions cells so that, it’s difficult to identify any diseases without using any computerized technology. Magnetic resonance imaging (mri) is one of the main assessments of brain tumors. One of the most important steps on medical image processing is segmentation. Segmenting brain mri images, which provide accurate information for the diagnosis and therapy decisions of brain tumors. We proposed to segment brain tumor mri images into three parts (wm (white matter), gm (gray matter), and background). The first algorithm is for applying median filtering on brain mri image for removing the noise from the image for achieving accurate results. The second algorithm is for applying k-means algorithm for accuracy in time consuming and for clustering into regions and the third algorithm indicate the detecting the boundary of the image with the use of level set. By comparison, our proposed method, its efficiency to segment perfectly more than other previous used algorithms especially on time consuming.
Correlation between Taste Threshold Sensitivity and MMP-9, Salivary Secretion, Blood Pressure, and Blood Glucose Levels in Smoking and Nonsmoking Women

Cigarette smoking can cause taste receptors to increase the taste threshold value. Consequently, the consumption of sugar and salt will not be controlled, therefore causing systemic diseases such as hypertension and diabetes. Nicotine and tobacco in cigarettes can stimulate MMP-9 which plays vital physiological roles in normal tissue growth and repair processes. This study aimed to find the correlation between taste threshold sensitivity and MMP-9, salivary secretion, blood pressure, and blood glucose levels in smoking and nonsmoking women. This was a cross-sectional study consisting of young adult women aged 18–24 years. Subjects were divided into two groups: the nonsmoking and smoking groups. In the combined data of both groups, the sweet taste threshold was correlated with age (r = 0.308, p=0.008), blood glucose levels (r = 0.238, p=0.043), and MMP-9 (r = –0.297, p=0.011). The salt taste threshold was only correlated with systolic blood pressure in the smoking (r = 0.440, p=0.032) and combined data groups (r = 0.260, p=0.026). By using partial correlation, it was shown that the relationship between the salt taste threshold and systolic blood pressure was influenced by smoking habits. The sweet taste threshold in women was found to correlate with age, blood glucose levels, and MMP-9 levels. On the other hand, there was a significant relationship between the salt taste threshold in women with systolic blood pressure, which was the only correlation analyzed in sthis study that was found to be influenced by smoking. However, both sweet and salt taste thresholds were not statistically correlated with salivary secretion.
