Comparison of the efficiency of the WPT system using circular or square planar coils

The article presents results for numerical analysis of Wireless Power Transfer (WPT) system consisting of transmitting and receiving plane coils. Two types of coils (circular and square) were included in the analysis. The influence of the type of coils, the number of turns and the distance between the coils on the efficiency of the WPT system was compared. The analysis covered a wide range of frequencies from 100 kHz to 1000 kHz. The Finite Element Method (FEM) with the using antiperiodic boundary conditions for the analysis was used. In the low frequency range (within the analysed range) the higher efficiency is for the WPT system composed of square coils. On the other hand, at higher frequency values, higher efficiency values were obtained for the WPT model containing circular coils. Proposed WPT system could be used to charge electric devices as the wireless power transfer system. The results indicate at which system parameters wireless energy transfer is possible. Streszczenie. W artykule przedstawiono wyniki analizy numerycznej systemu Wireless Power Transfer (WPT) składającego się z cewek płaskich nadawczo-odbiorczych. W analizie uwzględniono dwa rodzaje cewek (okrągła i kwadratowa). Porównano wpływ rodzaju cewek, liczby zwojów oraz odległości między cewkami na sprawność układu WPT. Analiza obejmowała szeroki zakres częstotliwości od 100 kHz do 1000 kHz. Do analizy wykorzystano Metodę Elementów Skończonych (MES) z wykorzystaniem antyperiodycznych warunków brzegowych. W zakresie niskich częstotliwości (w analizowanym zakresie) wyższa sprawność występuje dla układu WPT złożonego z cewek kwadratowych. Natomiast przy wyższych wartościach częstotliwości wyższe wartości sprawności uzyskano dla modelu WPT zawierającego cewki okrągłe. Proponowany system WPT mógłby służyć do ładowania urządzeń elektrycznych jako bezprzewodowy system przesyłania energii. Wyniki wskazują, przy jakich parametrach układu możliwy jest bezprzewodowy transfer energii. (Porównanie sprawności układu WPT z wykorzystaniem okrągłych lub kwadratowych cewek płaskich).
UDC 628.3:543.2 COMPLEX ASSESSMENT OF BIOSOLID FOR AGRICULTURE USING LIVING ORGANISMS UNDER LABORATORY CONDITIONS

The use of biosolids (treated municipal sewage sludge) as a fertilizer is the best way of their disposal. However, not all of them are suitable for use as a fertilizer. Biosolids should be subject to mandatory laboratory control to confirm their safety. Two directions of research on biosolids are being improved: chemical and biological. Chemical analysis methods allow us to determine the qualitative composition of complex waste. The biological approach (use of living organisms) allows us to estimate the total toxicity of all the components. Accordingly, a distinctive characteristic of biological methods is the integrated approach. We examined biosolid extract using a wide range of bioassay methods. As test organisms, we took Daphnia magna Straus, Paramecium caudatum Ehrenberg, Tetrahymena pyriformis, luminescent bacteria Escherichia coli. In addition, a phytotest was carried out on the culture of Avena sativa L. and Raphanus sativus L. None of the tests revealed a high toxicity of biosolid. Biosolid safety was confirmed by a low content of potentially toxic water-soluble elements – (μg /l): Al – 980; Ba – 19; B – 140; Mn – 360; Cu – 61; As – 57; Ni – 200; Pb – 1,4; Sr – 302; Cr – 18; Zn – 310; Co – 30; Mo – 56; (mg/l): Na – 16,8; Fe – 1,0. The bioassay methods make it possible to give an indicative safety assessment of this type of object by the effect of readily soluble (readily available) components from this object on living organisms and plants. The use of bioassay methods using soil extraction as a control tool allows to take into account the combined effect of the presence in the extraction of not only toxic elements that suppress the vital activity of organisms, but also of elements that attract and stimulate the activity of test-organisms.
Personal Health and Sentiments in Tweets

This paper presents results of sentiment analysis in Twitter messages that disclose personal health information. The messages discuss ailment, treatment, medications, etc. Recognition of sentiments and opinions is a challenging task for humans as well as an automated text analysis. In this work, we apply both the approaches. The paper presents the annotation model, process of sentiment recognition in health-related messages, and reports the results of the annotation agreement. For exter-nal evaluation of the labeling results, we apply Machine Learning meth-ods on multi-class and binary classiﬁcation of sentiments. Our reported Machine Learning results are comparable with previous results in the subjectivity analysis of user-written Web content.
Supporting Computational Music Remixing with a Co-Creative Learning Companion

Intelligent learning environments have demonstrated effectiveness for providing individualized instruction to students of computer science (CS). However, the great potential of intelligent agents has not yet been explored within expressive environments, which are increasingly common for supporting and motivating K-12 students. This paper presents the prototype design and implementation of a novel Co-creative Artiﬁcial Intelligence (CAI) integrated within EarSketch, an online environment for learning introductory computing concepts through code-driven, sample-based music remix-ing. CAI is intended to scaffold student learning from EarSketch’s expressive computing curriculum by co-creating algorithmic music alongside a human learner. This paper presents an initial version of CAI, which engages with EarSketch users by offering menu-based dialogue and suggestions based on the state of a project. We report a pilot study in classrooms, showing promising results in students’ satisfaction with the system’s capabilities. The ﬁndings of this pilot study suggest the ability of a co-creative agent to support users in learning and creative objectives, and should inspire research into combined computational and creative user models.
Papel do receptor NLRP12 na modulação da reabsorção óssea durante a progressão da lesão periapical experimental

NLRP12 is an intracellular sensor that recongnizes PAMPS and DAMPs during infeccion. It was seen that NLRP12 transcription is down-regulated during osteoclastogenesis, and NLRP12 protect bone via suppression of alternative NF-κB-induced osteoclastogenesis. It has been shown that NLRP12 deficiency in monocytes under RANKL stimuli exhibited more stabilization of NIK and nuclear translocation of RelB, increasing osteoclasts formation in vitro. Therefore, the aim of this study was to evaluate the role of NLRP12 in the development and progression of experimentally induced periapical lesions in mice. Periapical lesions were induced in first molars of WT and NLRP12 knockout (KO) mice. Samples were collected at 14 and 21 days of the lesion for the analyses. Jaw samples with lesion and control area were subjected to periapical lesions area determination by histological sections; osteoclastogenic markers expression by q-PCR; count of osteoclasts submitted to the enzyme assay for TRAP; evaluation of MMPs activity by Zymography. The expression of T cells markers’ transcription factors was evaluated in lymph nodes by q-PCR. Fourteen days after periapical lesion induction, histological analysis revealed that NLRP12KO mice exhibited higher area of periapical lesion compared to WT group, which was associated with upregulated mRNA expression of Trap, Cathepsin K and MMP-9 in the jaw samples. Moreover, the number of multinuclear TRAP-stained cells was significantly higher in the NLRP12KO with lesion group when compared to it control, whereas in the WT the number between the lesion and control groups were similar. Still, NLRP12KO showed higher MMP-9 and -2 gelatinolytic activity than it control, unlike WT mice that showed no difference between control and lesion group. In this period, NLRP12KO mice lymph nodes showed more RORγt expression than WT mice and less T-bet expression. At 21 days, WT and NLRP12KO presented periapical lesions of similar sizes. In addition, NLRP12KO group with lesion showed a significant increase in Trap expression when compared with their control, but the increase in Trap e Cathepsin K was similar in both groups. Additionally, there was an increase of multinuclear TRAP-stained cells in both lesion groups when compared with their respective controls; however, there was also no difference between WT and NLRP12KO mice. MMP-9 and -2 activity was similar between WT and NLRP12KO and with their respective controls at 21 days. Our results suggest that NLRP12 deficiency led to increased bone loss at 14 days of periapical lesion and it occurs due to increased osteoclasts formation and activity. Therefore, NLRP12 inhibits osteoclastogenesis and osteoclasts activity during the early stages of periapical lesion, slowing the development of the disease. Keys-word: NLRP12, periapical lesion, bone resorption, MMP-9, osteoimmunology.
EFFECT OF SURFACE MODIFICATION ON THE SORPTION CAPACITY OF Piliostigma reticulatum AS A SORBENT FOR CRUDE OIL REMOVAL FROM WATER

The need to seek inexpensive, abundant and effective materials as oil spill sorbents in water has focus on natural organic sorbents mainly from agricultural products. This study explored the used of crude Piliostigma reticulatum (CPR), retted Piliostigma reticulatum (RPR), bleached Piliostigma reticulatum (PFPR) fiber as sorbent for crude oil removal from water. Sorption capacity studies was carried and optimization at various condition. The results revealed that the efficiency of sorbent to remove crude oil from water is related to the sorbent weight, contact time, initial oil concentration and temperature of sorption. RPR with the highest sorption capacity of 7.92 g/g at 0.7 g of the sorbent was selected and modified through acetylation, succinoylation in ionic liquid, silanylation and salt treatment. The functional groups involved in oil sorption were identified via the determination of the chemical structure of the sorbents before and after oil sorption. Change in the spectral peaks of the sorbents after absorption of crude oil at wave number 2922. 3 cm corresponding to -CH alkane stretching, can be attributed to addition of crude oil. The SEM images show some wrinkles and roughness on the surface of the pretreated and modified sorbents. The elemental composition of the sorbent before treatment and after treatment reveals a reduction in oxygen availability as evidenced by the decrease in peak height of oxygen signal. The sorption capacity of the modified sorbent was compared to that of the pretreated sorbent RPR, to check the sorption capacity after chemical treatment. 0.3 g of the sorbent was used with contact of 20 min at initial oil concentration of 10 g/mL at temperature of 30C. RPR has the least oil removal capacity of 5.69 g/g, compared to ACT-PR (7.79 g/g), SIL-PR (7.70 g/g), SUC-PR (6.84 g/g) and ZN-PR (9.31 g/g). Surface-modified sorbent has noticeable high oil sorption capacity compared with the retted sorbent. RPR attained its highest sorption capacity of 7.92 g/g at 0.7g of the sorbent weight, while ACT-PR, SIL-PR, SUC-PR, ZN-PR attained the highest sorption capacity of 10.51, 10.12, 8.52 and 11.05 g/g at 0.5 g of the sorbent weight after optimization. The sorbent exhibited good reusability after 8 cycles and RPR, ACT-PR, SIL-PR, SUC-PR and ZN-PR losses 33, 18, 17, 22 and 16%, respectively of the initial adsorb oil showing good retention capacity. Effective replacements of hydrophilic hydroxyl groups of fibers by the hydrophobic groups during modification improves its the affinity toward oil.
How Bangladeshi Students Reacted to Online Education During the Covid-19 Pandemic to Adjust to a Post-Lockdown Period

Following an extraordinary condition of confinement due to the Covid-19 epidemic, academic institutions were urged to focus on supporting telecommunications technology. Higher education went entirely online for the first time. The authors of this study performed an online voluntary survey in which Greek students were asked questions regarding the distant education they had received during the Covid-19 shutdown, particularly the synchronous variety. The goal of this study was to look at the primary difficulties that hampered students' learning, both technological hurdles that made communication difficult and teaching/learning challenges that arose because of growing trends. Recognizing the major issues that occurred in the educational process during the lockdown period will lead to improved communication in the field of remote education in the future. The research was shared with the students not just through their institutions' Student Counseling Centers, but also through articles on well-known student content websites. According to the findings of the research, most students attended synchronous communication online classes (theoretical and practical) in place of their face-to-face sessions. Students raised concerns about synchronous communication instructional techniques, as well as how their lessons were arranged and presented. They alluded to the primary technical issues that happened on the teacher's side -preventing appropriate communication, as well as the practices that stressed them or the lack of contact between students and instructors that they encountered during the lockdown. Despite these issues, most students are interested in furthering their education through online learning in addition to regular classroom courses. Overall, this survey offered valuable supplementary information about students' attitudes regarding online education during the first quarantine period.
A Contrastive Study of Temporal-Spacial Metaphors in English, French and Chinese

Due to the intangibility and abstractness of time, people from different cultures, though with disparate views on time and space, are universally inclined to project spacial metaphors on temporal concepts. Nonetheless, most research has put more emphasis on the bilingual contrastive study than the multilingual one, leaving the generalizability of their research findings questioned. Guided by Lakoff’s conceptual metaphor theory, this paper analyzes both static and dynamic temporal-spacial metaphors in English, French and Chinese with both lexicographical data and corpora data as proof. Moreover, through contrasting the six image schematic concepts in the three languages, namely, UP, DOWN, LEFT, RIGHT, FORNT, and BACK, this paper notices the most conspicuous disparages between the three languages exist in their vertical and horizontal representations of temporal-spacial metaphors. Additionally, through comparison, this paper unveils the similarity of the three languages with regard to their use of both the moving-ego, the moving-time and the temporal-sequence models in their metaphorical systems.
Web-Based Crowd Sentiment Analysis: Methods

— Today, large population use social networking sites like Facebook, Twitter, LinkedIn etc. Through social media, people share messages, photos. They also impart information about a particular event or speciﬁc situation. There is limited research on crowd management to handle a disaster. In this paper, we focus on Crowd Management using Sentiment Analysis as a tool for safety in some events or situations. People convey their emotion about crowd using social sites. Crowd-related issues encountered day to day life such as stations, shopping malls, and stadiums or some events like marriage which may cause congestion and due to that some people may be injured or causes death. Peoples post their sentiments through Twitter, LinkedIn etc. In this paper, tweets are collected from social networking site Twitter. These sentiments contain the list of expressions which have some polarity value. We use a rule-based algorithm for sentiment analysis. Public opinion can be classified into either positive, negative or neutral sentiment. The public opinions are then collected, processed and analyzed using data mining techniques. The proposed system is based on a rule-based algorithm. Polarity score of the sentence is calculated through SND pattern. To improve the accuracy of the proposed system we collect data from some other social networking site.
MOLECULAR STUDY OF IL-18 POLYMORPHISM IN FEMALE ABORTED INFECTED WITH HUMAN HERPES VIRUS-6

Background : Human herpesvirus 6 (HHV-6) can integrate into human chromosomes, resulting in genetic transmission from parent to child. Individuals of either sex with inherited chromosomally integrated human herpesvirus 6 (iciHHV-6) harbor the virus in every cell. Viral reactivation from the integrated HHV-6 genome can occur in pregnancy. Interleukin-18 (IL18, also known as interferon-gamma inducing factor) is a protein which in humans is encoded by the IL18 gene. Patients and Methods This case control study was done for a one hundred-fifty specimens collected from female patients subjected to recurrent pregnancy loss and apparently healthy persons as control group. All these specimens were submitted for genetic part for screening human Herpes virus-6 (HHV-6) in patients and apparently healthy person control groups by real time polymerase chain reaction (RT-PCR). Results :The positive result of HHV-6 –DNA according to qRT-PCR shows 43.1% (25 out of 58 cases) as positive while 56.9% (33 out of 58 cases) was negative. According to the results of IL-18 polymorphism , both of CC and CG were statistically higher than those of the control group according to the gene expression levels (P<0.05) . Conclusion: HHV6 might be one of the most recently identified uterus, cervical viruses in iraqi female patients suffering from recurrent miscarriage. In addition, highly serum concentration of IL-18 level in women patients with RPL could point for its possible roles in protective against pathogenesis of women patients suffering from recurrent miscarriage.
A New Mode Stirrer Design for the Reverberation Chamber

─ In this paper, a mode stirrer composed of random positioned metal plates is proposed for reverberation chamber. The designing procedure of the mode stirrer is presented. The designed stirrer is compared with the common Z-shaped stirrer in both simulation and measurement. It is shown that in general the proposed stirrer outperforms the common Z-shaped stirrer with the same sweeping volume. Nevertheless, the measurement results show that the performance improvement of the designed stirrer becomes insignificant at higher frequencies with additional platform stirring. Albeit the difference, the stirring improvement of the designed stirrer is clearly demonstrated at low frequencies, which is more important due to the inherent low mode density at low frequency. Index Terms ─ Independent sample number, measurement uncertainty, mode stirrer, reverberation chamber.
A Prospective Randomized Study to Compare the Ease of Tracheal Intubation using Truview, Airtraq and Macintosh Laryngoscopic Blades

1 Department of Anesthesia , HN Reliance Foundation Hospital, Mumbai, India 2 Associate Professor, Department of Anaesthesia, Seth GSMC, KEM Hospital, Mumbai, India 3 Department of Anaesthesia, Seth GSMC, KEM Hospital, Mumbai, India *Corresponding Author Oak Shrikanta P. DA, DNB Abstract Introduction: Anaesthesiologists face several complications during tracheal intubation, inability to intubate being the most devastating. Macintosh has been the gold standard since times immemorial. Newer indirect laryngoscope blades have come into vogue which improve visualization of glottis. In our study we compare the ease of tracheal intubation between direct and indirect laryngoscopes. Methods: Ninety consenting patients were included in this prospective randomized controlled trial to compare the ease of tracheal intubation using Truview(Group 1), Airtraq (Group 2) and MacIntosh (Group 3) laryngoscope blades. The time taken for intubation, intubation difficulty score, hemodynamic changes with intubation and complications were observed and compared. Results: There was no statistically significant difference between the three blades with respect to duration of intubation (p =0.3), intubation difficulty score or complications. Statistically significant difference in pulse, mean arterial pressure at 1,3 and 5 minutes post intubation was found between the groups. Therise in pulse was found to be significantly lesser in Group 1(p value-0.001) and Group 2(p value0.040) when compared to Group 3 at 3 minutes and significantly lesser in Group 1 when compared to Group 3(p value-0.041) at 5 minutes . Rise in mean arterial pressure (MAP) was significantly lesser in Group 2 when compared to Group 3 at 1 minute (p value0.038) and 3 minutes (p value0.026) after intubation. Conclusion: Airtraq provides certain advantages over Truview and Macintosh in terms of ease of intubation and hemodynamic stability when used by experienced anesthesiologists in a normal airway.

ACTIVITY OF APIGENIN AND QUERCETIN ON RAT HEPATIC MITOCHONDRIAL PERMEABILITY TRANSITION PORE

Background: Alteration of mitochondrial functions such as permeability transition has been found to play a vital role in the apoptotic process induced by certain anti-cancer agents. Phenolics such as quercetin and apigenin commonly found in many fruits and vegetables, is known for its potential anti-tumor properties. Objective: This study was carried out to investigate the effect of quercetin and apigenin in vitro on mitochondrial membrane permeability transition pore (MMPT). Methodology: Opening of MMPT pore was assessed as mitochondrial swelling and was monitored spectrophotometrically as changes in absorbance at 540 nm under succinate-energized condition. Results: The results obtained showed that calcium ion induced the opening of MMPT pore significantly (P<0.05) in rat hepatic mitochondria while spermine inhibited calcium-induced opening of MMPT pore. In contrary to the effect of quercetin in the absence of exogenous Ca, apigenin significantly (P<0.05) induced pore opening in a concentration dependent manner. The inductive effect of apigenin is higher than that caused by Ca only. The percentage induction of apigenin at 10μg/ml, 20μg/ml, 40μg/ml and 80μg/ml are 88.50%, 91.72%, 91.93% and 92.02% respectively while that of Ca is 88.28%. Also, in the presence of Ca, apigenin further induced the opening of the pore significantly (P<0.05) in concentration dependent manner when compared with the calcium only. Apigenin at all concentration tested enhanced the mitochondrial F1F0 ATPase activity. Our results demonstrate that apigenin induces cell death through mitochondriamediated pathway of apoptosis. These findings suggest that apigenin could be useful in situations of dysregulated apoptosis such as cancer.
