Limited knowledge exists about the effects of commonly used diuretic medications on the human normal flora. Thus, we investigated potential stimulatory effects of diuretic drug furosemide on urogenital tract microbiota in women. Three strains of E. coli and C. albicans with different biofilm forming capacities were obtained from female patients diagnosed with urinary tract infections. All tested strains were treated with two different concentrations of furosemide drug, in comparison to non-treated strains as the negative control. At specific time intervals, samples were obtained from growing culture and analyzed for their proliferation rate, aspartyl proteinase excretion and biofilm formation ability. E. coli and C. albicans strains significantly increased their aspartyl proteinase excretion under furosemide treatment. This effect was frequently observed after 16 hours of incubation at 37oC. This drug has also increased the biofilm forming capacities of E. coli and C. albicans strains. Interestingly, both E. coli and C. albicans non-biofilm former strains, gained the capacity of biofilm formation when treated with furosemide at certain concentrations. E. coli control became a weak biofilm former after 48 hours of incubation, while non-biofilm former C. albicans strain became a weak biofilm former in dose-dependent fashion, after 48 hours incubation with furosemide in concentration of 0.1 mg/mL, and after 16 hours of incubation with furosemide in concentration of 0.5 mg/mL. Loop diuretic drug furosemide is able to increase the microbial virulence and turn commensal microbes into opportunistic pathogens. Additionally, the results suggest that enzyme aspartyl proteinase might act as a signal molecule for the biofilm formation, leading to the increased microbial pathogenicity.

Civil Engineering Structures which are been constructed and are being constructed were mostly analysed and designed using STAAD.PRO software and the cost estimation is made in MS Excel. As both these tools have made the analysis, design and estimation an easier task. But in discussing about in favour of these, durability of many structures are failing in seismic zones. As to make this as a note many engineers and researchers are been struggling in solving the problem of failures in the construction Industry. Here, we are considering a method of response spectrum in ZONE-II. By considering this method would able to control the structure against failure to seismic loads. Then while on coming to estimation of the structure, the only thing that worries is when execution started the cost either may increases or may decreases. We, in this research paper have given the factors that influence the change in cost of project on pre-construction and post construction.

One of the main difficult tasks in the field of micro-robotics is the process of the selection of the optimal parameters for the PID controllers. Some methods existed to solve this task and the common method used was the Ziegler and Nichols. The former method require an accurate mathematical model. This method is beneficial in linear systems, however, if the system becomes more complex or non-linear the method cannot produce accurate values to the parameters of the system. A solution proposed for this problem recently is the application of optimization techniques. There are various optimization techniques can be used to solve various optimization problems. In this paper, several optimization methods are applied to compute the optimal parameter of PID controllers. These methods are flower pollination algorithm (FPA), grey wolf optimization (GWO), sin cosine algorithm (SCA), slime mould algorithm (SMA), and sparrow search algorithm (SSA). The fitness function applied in the former optimization techniques is the integral square Time multiplied square Error (ISTES) as the performance index measure. The fitness function provides minimal rise time, minimal settling time, fast response, and no overshoot, Steady state error equal to zero, a very low transient response and a non-oscillating steady state response with excellent stabilization. The effectiveness of the proposed SSA-based controller was verified by comparisons made with FPA, GWO, SCA, SMA controllers in terms of time and frequency response. Each control technique will be applied to the identified model (simulation results) using MATLAB Simulink and the laboratory setup (experimental results) using LABVIEW software. Finally, the SSA showed the highest performance in time and frequency responses.

Identifying Vehicle Model Parameters Using Remote Mounted Motion Sensor
Authors: Hwang Yoonjin
Published: September 2021

The recent developments on advanced driver assistance
system(ADAS) have extended the capability of sensor systems from
surrounding perception to motion estimation. The motion estima?tion provides tri-axial velocity and pose measurements, which open
potential benefits for control and state estimation through sensor
fusion with the vehicle dynamics model. In this paper we propose an
identification method for the vehicle single track model parameters
including the relative distance between the vehicle center of gravity
and the motion sensor. A linearized tire force model and simplified
single track vehicle model are constructed with the corresponding
sensor kinematics model. We demonstrate the efficacy of iden?tification performance of the proposed method and confirm the
feasibility of the usage of ADAS sensor in vehicle dynamics and
vice versa

Published: September 2021

Accurate segmentation of rectal cancer and rectal wall based on high-resolution T2-weighted magnetic resonance imaging (MRI-HRT2) is the basis of rectal cancer staging. However, complex imaging background, highly characteristics variation and poor contrast hindered the research progress of the automatic rectal cancer segmentation. In this study, a multi-task learning network, namely mask segmentation with boundary constraints (MSBC-Net), is proposed to overcome these limitations and to obtain accurate segmentation results by locating and segmenting rectal cancer and rectal wall automatically. Specifically, at first, a region of interest (RoI)-based segmentation strategy is designed to enable end-to-end multi-task training, where a sparse object detection module is used to automatically localize and classify rectal cancer and rectal wall to mitigate the problem of background interference, and a mask and boundary segmentation block is used to finely segment the RoIs; second, a modulated deformable backbone is introduced to handle the variable features of rectal cancer, which effectively improves the detection performance of small objects and adaptability of the proposed model. Moreover, the boundary head is fused into the mask head to segment the ambiguous boundary of the target and constrain the mask head to obtain more refined segmentation results. In total, 592 annotated rectal cancer patients in MRI-HRT2 are enrolled, and the comprehensive results show that the proposed MSBC-Net outperforms state-of-the-art methods with a dice similarity coefficient (DSC) of 0.801 (95\% CI, 0.791-0.811), which can be well extended to other medical image segmentation tasks with high potential clinical applicability.
Bootstrap Empirical Mode Decomposition with Application to CIELAB Color Images
Authors: Lum Kai-Yew
Published: September 2021

This paper proposes an alternative optimization-based EMD based on the notions of: 1. local mean points that impose mode symmetry via a Tikhonov regularized least-square (RLS) problem, and 2. efficient bootstrap sifting that guarantees asymptotic convergence of the mean envelope to the local mean points, regardless of regularization. Mathematical proof of convergence and a straightforward extension to the 2D-multivariate setting and CIELAB color image sare presented. Performance is demonstrated with a univariate signal and two images. Spectral analysis confirms coordinated feature extraction among image components, and separation of spatial spectra among the intrinsic mode functions.

Published: September 2021

In Robert Walser’s work any intention of meaning would seem to be revoked in doubt, in favour of blatant mannerism. This, in turn, would take the actual form of a proclaimed abstention from the pursuit of any purpose, so as to be similar to a simple graphic texture. The aim of this article is to show how this peculiar textual economy favours the invention of a subject capable of giving rise to a fictitious identity to the point of no longer being able to distinguish any gap between reality and fiction.

Authors: Ponimin  , Guntur
Published: September 2021

This paper reports on the production of a ceramic installation artwork that explores the story of the COVID-19 pandemic experienced by people throughout the world. The work is a symbolic expression in the form of a set of ceramic art models that portray the story of the battle between positive and negative values, expressed through a 3-dimensional visual ceramic installation consisting of an arrangement of statues that portray an imaginary battle between COVID-19 troops and Lord Krishna. The method used in the process of creating this work was a creative approach that combined appreciation and interpretation of the object of the creative idea. The artwork was made of plastic clay taken from the southern area of Malang regency, East Java, Indonesia, which was formed using a manual technique of direct hand massage and fired at a temperature of 900 °C. The COVID-19 phenomenon is imagined and visualized as a ceramic installation sculpture consisting of the imaginative figures of COVID-19 troops, led by the king of COVID-19 who is shown fighting with Lord Krishna. The result is a visual expression of the COVID-19 troops and their king, in several imaginative forms, carrying various weapons of war, in combat with the imaginary figure of Lord Krishna. The distinction of this work is its portrayal of a battle between positive and negative forces that have become a part of human life during the COVID-19 pandemic, expressed in a symbolic visual narrative through the arrangement of a set of ceramic sculptures.

Published: September 2021

Citrus vein enation virus (CVEV) was described in Spain and then it has been reported in several citrus growing areas of Asia, America and Australia. Here, the occurrence of CVEV in Italy has been documented for the first time. The full genome sequence of a CVEV Italian isolate (14Q) was determined by high-throughput sequencing and the presence of the virus was confirmed by RT-PCR and graft-transmission to indicator plants, from which the virus was recovered six-months post-inoculation. Phylogenetic analysis based on the full-length genome of CVEV isolates from different countries showed that they are phylogenetically related to each other based on their geographic origin, rather than on their host and that the Italian isolate is more closely related to the Spanish isolate than to the other ones. A field survey revealed the presence of CVEV in some areas of Campania region (southern Italy), prevalently infecting lemon trees. In the frame of this survey, kumquat was identified for the first time as a host of CVEV. No symptoms were observed in the field so far. The infection of asymptomatic hosts and the transmission by aphid species present in Italy increase the risk that the virus could further spread.
MODERN MODELS OF HYBRID WAR
Authors: Дугінець А. В. , Бусарєва Т. Г.
Published: September 2021

As a result of large-scale processes and trends that have taken place in recent decades in the context of globalization and the information revolution, forms, methods, means and, accordingly, interpretations of national interests and national security are being more or less noticeably metamorphosed. Against this background, in recent years, the concept of "hybrid wars" has rapidly entered the military-political lexicon. It is not only firmly established in the scientific and journalistic literature, as well as in the media, but is also widely used in official documents determining the behavior of states in the international arena. New concepts and methods of conducting hybrid war are developing very rapidly today, which requires a revision of the classic military methods of forecasting and planning both offensive and defensive strategies. Like any other war, gybrid war is an area of unreliability and uncertainty. The inaccuracy of intelligence and the constant intervention of chance lead to the fact that the parties to the conflict actually face a completely different situation than expected, and this can not but affect the planning or at least the perceptions of the situation that formed the basis of strategic plans. The transformation of hybrid warfare into a new type of interstate confrontation raises the issue of the use of modern tools of support and decision-making as a priority. The use of the hybrid war model for this purpose is increasingly going beyond the purely scientific sphere, making it an effective factor in ensuring the national security of countries. The development of effective hybrid warfare strategies and counter-strategies requires the introduction of new technologies based on the modeling and application of AI. The symbiosis of modern scientific knowledge and approaches allows us to study, predict and plan modern hybrid military conflicts as nonlinear objects operating in conditions of high uncertainty. Model, created for this purpose, should be easily integrated into the political and military decision-making process and, given the complexity of this activity, be integrated. This approach will provide an adequate understanding of the complex, ever-changing phenomena of hybrid warfare and hybrid threads and take them into account in the system of national and global security.

Authors: Pitta Rebecca Alekhya  , K. Tulasi Krishna Kumar Nainar
Published: September 2021

Recently, research intergrading medicine and Artificial Intelligence has attracted extensive attention. Mobile health has emerged as a promising paradigm for improving people’s work and life in the future. However, high mobility of mobile devices and limited resources pose challenges for users to deal with the applications in mobile health that require large amount of computational resources. In this paper, a novel computation offloading mechanism is proposed in the environments combining of the Internet of Vehicles and Multi-Access Edge Computing. Through the proposed mechanism, mobile health applications are divided into several parts and can be offloaded to appropriate nearby vehicles while meeting the requirements of application completion time, energy consumption, and resource utilization. A particle swarm optimization based approach is proposed to optimize the aforementioned computation offloading problem in a specific medical application. Evaluations of the proposed algorithms against local computing method serves as base line method are conducted via extensive simulations. The average task completion time saved by our proposed task allocation scheme increases continually compared with the local solution. Specially, the global resource utilization rate increased from 71.8% to 94.5% compared with the local execution time.

CONFIDENTIALITY PROTECTIVE USER PROFILE MATCHING IN PUBLIC NETWORKS
Authors: Maddala Mounika  , K. Tulasi Krishna Kumar Nainar
Published: September 2021

We consider a scenario where a user queries a user profile database, maintained by a social networking service provider, to identify users whose profiles match the profile specified by the querying user. A typical example of this application is online dating. Most recently, an online dating website, Ashley Madison, was hacked, which results in disclosure of a large number of dating user profiles. This data breach has urged researchers to explore practical privacy protection for user profiles in a social network. Here, we propose a privacy-preserving solution for profile matching in social networks by using multiple servers. Our solution is built on homomorphic encryption and allows a user to find out matching users with the help of multiple servers without revealing to anyone the query and the queried user profiles in clear. Our solution achieves user profile privacy and user query privacy as long as at least one of the multiple servers is honest. Our experiments demonstrate that our solution is practical.
KEY WORDS: User profile matching, data privacy protection, ElGamal encryption.

Published: September 2021

Concrete is the most important material in construction industry. Aggregate is one of the most important components of concrete, which consists of many different components. In this study, concrete of constant water/cement ratio was produced by using different types of aggregates, and the effect of aggregate on concrete properties was investigated. After determining the physical properties of the aggregates, the textural properties of the aggregates were investigated with the help of image analysis. Standard water cure was applied to concrete test samples for 7, 28, 90, and 180 days. After the curing process, the physical and mechanical properties of the samples were determined by destructive and nondestructive methods. Thin section samples were taken from hardened concrete samples, and cement aggregate interface investigations were performed under microscope. As a result, it has been determined that aggregate type creates a change in concrete strength, and this situation is related to aggregate properties.

To limit the losses in sprayed metal in the process of electric arc deposition, the disintegrating airflow is pulsated. In this work, the effect of changing the pulsation frequency was studied on the process performance, mainly, the efficiency of metal removal and rate of deposition. Additionally, the bonding strength of the resulting sprayed metal was evaluated at different pulsation frequencies. The application of air pulsations increases the productivity and efficiency of sprayed material by increasing the efficiency of material used up to 30% and enhancing the rate of deposition up to 32%, at a frequency range 70–80 Hz. Moreover, at the optimum frequency of air pulsations, the bond strength increased up to 69%, measured by Steffensen’s dowel method. The results found in this work will allow for more rational usage of the electrical arc energy and material.

‘Klinik Pakar Mata Bergerak’ (KLiP Mobile), translated to specialised ophthalmology mobile clinic is a programme that provides ophthalmology care in the rural community of Negeri Sembilan. This study was conducted to determine the prevalence of cataracts and its associated factors among rural adults in Malaysia through an outreach programme of specialised ophthalmology services by KLiP Mobile. This is a cross-sectional study carried out from January 2016 until March 2018 and was conducted in rural areas of all seven districts in the state of Negeri Sembilanvisited by the KLiP Mobile. Universal sampling was applied to all adults attending the mobile clinic. The participants are those who were referred by the government community clinics and walk-in patients. The total number of participants in this study was 1480. The mean (SD) age for the study population was 56 (16.9), by which majority were Malay (n = 1220, 82.4%) and female (n = 809, 54.7%). Most of them received either primary (n = 604, 42.4%) or secondary education (n = 577, 40.5%). The majority of participants were categorized into the low-income group, with a monthly income of less than RM 3,000 (n = 1118, 92.4%). The prevalence of cataracts in the study population was 28.6%. In the multivariate analysis, factors significantly associated with cataracts were being male, having no formal education, race and suffering from hypertension. The prevalence of cataracts in rural areas is considerably high. This study highlights the need for baseline information for future study or as the main reference by the policymakers for policy development related to improving vision and eye care among the populations in Malaysia.

Ice is widely used in food and drink establishments for refreshing drinks and food preservation. Therefore, the contamination of ice, especially microbial contamination, could be the vehicle for the transmission of pathogenic microorganisms to consumers. This study aimed to determine of bacteriological quality of ice sold at food and beverage premises. The sanitary conditions of the premises were also investigated. Edible ice samples from 12 premises were collected and analyzed coliform bacteria using the multiple-tube fermentation technique. Modified food sanitation inspection form from the Bureau of Food and Water Sanitation, Department of Health, Ministry of Public Health, was used for inspection of food and beverage premises. It was found that all samples were positive for coliform bacteria, ranging from 140 - > 24,000 MPN/ 100 mL, which is inconsistent with the standard permission level in terms of total coliform bacteria of the Thailand office of Food and Drug Administration. Ice storage and the handwashing behaviour of food handlers were the main sanitary issues found from the sanitary conditions survey. The finding of this study urges the regulatory guidelines for monitoring ice quality and the sanitary conditions of food and beverage premises to protect the consumers’ health from the consumption of unsafe ice.

Published: September 2021

A new mineral species, liudongshengite, ideally Zn4Cr2(OH)12(CO3)·3H2O, has been found in the 79 mine, Gila County, Arizona, USA. It occurs as micaceous aggregates or hexagonal platy crystals (up to 0.10 × 0.10 × 0.01 mm). The mineral is pinkish and transparent with white streak and vitreous luster. It is brittle and has a Mohs hardness of ∼1.5, with perfect cleavage on (001). No twinning or parting is observed macroscopically. The measured and calculated densities are 2.95 (3) and 3.00 g/cm3, respectively. Optically, liudongshengite is uniaxial (−), with ω = 1.720 (8), ε = 1.660 (7) (white light). An electron microprobe analysis, combined with the carbon content measured using an elemental combustion system equipped with mass spectrometry, yielded the empirical formula (Zn3.25Mg0.17Cr2.58)Σ6.00(OH)12(CO3)1.29·3H2O, based on (M2+ + M3+) = 6 apfu, where M2+ and M3+ are divalent and trivalent cations, respectively.

Liudongshengite belongs to the quintinite group within the hydrotalcite supergroup and is the Cr-analogue of zaccagnaite-3R, Zn4Al2(OH)12(CO3)·3H2O. It is trigonal, with space group Rm and unit-cell parameters a = 3.1111(4), c = 22.682(3) Å, and V = 190.12(4) Å3. The crystal structure of liudongshengite is composed of positively charged brucite-like layers, [M2+1–xM3+x(OH)2]x+, alternating with negatively charged layers of (CO3)2–·3H2O. Compared to other minerals in the quintinite group, liudongshengite is remarkably enriched in M3+, with an M2+:M3+ ratio of 1.33:1. Like zaccagnaite-3R and many other hydrotalcite-type minerals, liudongshengite may also possess polytypes, as a series of synthetic hydrotalcite-type compounds with a general chemical formula [Zn4Cr2(OH)12]X2·4H2O, where X = Cl–, NO3–, or ½ SO42–, but with unit-cell parameters different from those for liudongshengite, have been reported previously.

This article is devoted to the problem of the implementation of modern linguistic approaches to teaching word formation to Chinese students of philology. The methodological foundations of teaching functional word formation to foreign students in Russian linguistic are presented. The necessity of using a comparative approach in teaching word formation and the principle of reliance on the native language of students is substantiated. The mechanisms of word formation in the Chinese and Russian languages are compared. The difficulties encountered by Chinese students are analyzed, practical tasks aimed at developing students' skills such as conducting word-formation analysis, seeing the word-formation structure of new lexical units, differentiating similar morphemes are presented. Much attention is paid to stylistic word formation and the formation of the skill of the correct use of stylistically marked derivatives in various functional styles.

Ischemic or hemorrhagic stroke may be accompanied by movement disorders (1), either hyperkinetic or hypokinetic. Hyperkinetic movement disorders after stroke comprise dystonia (2-4), chorea with or without hemiballismus (5), tremor (6), parkinsonism (7), segmental or focal myoclonus, athetosis, pseudathetosis, and asterixis (8). Hemiballismus is a movement disorder characterized by involuntary, arrythmic, and large amplitude excursion of a limb, usually from a proximal joint, witn an element of rotation (9). Ballismus is explainable with lesions in the subthalamic nuclei, cerebral cortex, corpus striatum, thalamus and brainstem. (10) The frequency of post-stroke abnormal movements is unclear, the prevalence in a swiss registry being 1% with an incidence of 0.08% per year (8). Of them, hemichorea-hemiballismus is the most common, while dystonia is the next most common disorder (11).

This study aims to develop and validate NIR-chemometric methods for quantifying the API (quetiapine) and two excipients in extended-release tablets without sample preparation. The calibration samples were prepared following an experimental design with three variables (quetiapine, HPMC and microcrystalline cellulose) and five levels (concentration 80-90-100-110-120% of API). The validation set included three concentration levels (90-100-110%). The best calibration algorithms have used the same pre-treatment method (SNV), and different factors: 7 PLS factors (R² -0,966 and RMSEP-6,84) for quetiapine, 8 PLS factors (R²-0,927 and RMSEP 6,84) for HPMC and 3 PLS factors (R²-0,983 and RMSEP-7,26) for microcrystalline cellulose. The methods were fully validated according to the ICH guidance using these calibration models. Regarding the trueness of the methods, the recovery was between 98.51 and 99.43 for quetiapine, between 98.61 and 100.85 for HPMC, and between 100.61 and 101.78 for microcrystalline cellulose. According to data obtained, the accuracy profile was ± 5 for quetiapine and HPMC, and ± 6 for microcrystalline cellulose. Linearity profile was also in establish intervals at accuracy and the R2 value was 0.983 for quetiapine, 0.948 for HPMC and 0.997 for microcrystalline cellulose. In conclusion, the developed NIR-chemometric methods have suitable reproducibility, accuracy, linearity and can be used for quantitative characterisation of extended-release tablets with quetiapine, with any sample preparation.

Objectives. The current paper aims to obtain an overview regarding the use of parenteral medicines recommended for the pediatric sector and delivered in Romanian community pharmacies. Materials and methods. A retrospective observational study was developed, based on a questionnaire which was distributed in community pharmacies in Romania. Results. The parenteral medicines were delivered in 100 community pharmacies which partake in the study, and which are distributed in 22 counties in Romania. The total number of parenteral medicines considered in the study were aimed for pediatric use and they represented approximately 5% of the total number of medicines prescribed for children delivered in the respective pharmacies. Of these, most of them are medicines authorized for adults, delivered for off-label use, by other routes of administration, in their original form or reformulated in the form of other pharmaceutical preparations, during the compounding activity in the pharmacy. Conclusions. The parenteral medications most prescribed for pediatric use and delivered in community pharmacies are injectable solutions and powders for parenteral use. They are used as off-label medication in children, by other routes of administration, both to capitalize the therapeutic action of the active principle, and also as a vehicle for other medications with oral route or external route of administration.
