Design of single‐band antenna with T‐shaped patch for wireless applications

In this paper, a novel compact patch antenna is presented for wireless communication applications. The proposed antenna has three T‐shaped patches (TSP) connected to the feed line and crossed I‐slots are etched on the ground plane to operate a single resonating band with low interference. The TSP antenna operating frequency is 10.98 GHz with an impedance bandwidth of 850 MHz, a reflection coefficient of −38.11 dB, and a gain of 6.44 dBi. The radiation patterns are also presented for E‐plane and H‐plane. The proposed TSP antenna model is fabricated and tested. Good agreement is achieved with simulated and measured results.
Effect of aromatic oils on the expression of some virulence-associated and antimicrobial resistance genes of Escherichia coli isolated from broilers

Objectives: This study aimed to prove the effects of Escherichia coli isolates isolated from diseased broilers to form biofilms, describe their antimicrobial sensetivity, and determine the effect of allicin and cinnamon essential oils on the expression of some genes (fimH, int1, and luxS) through quantitative polymerase chain reaction (q-PCR). Materials and Methods: 140 samples were obtained from diseased broilers in Beni-Suef Governorate, Egypt. These samples were examined by conventional bacteriology methods to detect the causative agent. The antimicrobial susceptibility of the isolated bacteria was assessed using the disc diffusion method, The ability of yeast extract-casamino acids Congo Red Agar to generate phenotypic biofilms was next tested. The presence of resistance and virulence genes in some multidrug resistant isolates was genotypically investigated. The antibacterial effects of allicin and cinnamon oil were evaluated against the growth of multidrug-resistant E. coli. Finally, q-PCR was utilized to assess changes in some genes’ expression. Results: Escherichia coli was isolated from 61 samples (43.6%). An antimicrobial susceptibility test revealed that multidrug-resistance (MDR) (could resist more than three antimicrobial classes) E. coli prevalence was 100%. 40.8% of isolates phenotypically produce biofilms. The detection of resistance and virulence genes by PCR showed that all tested isolates carry aadB, fimH, int1, qnrS, and luxS genes, while only 40% harbor iss genes. q-PCR showed that after treatment with allicin and cinnamon oils, gene expression went down. Conclusion: This investigation highlights that E. coli showed resistance against most of the tested antimicrobials; all isolates were MDR. The study showed wide dissemination of virulence and resistance genes among E. coli. Allicin and cinnamon oils have antimicrobial activities and could be used as alternatives to synthetic antimicrobial agents.

Influence of land‐use changes on microbial community structure and diversity in a semiarid region

Land‐use change and the conversion of land into croplands is one of the main drivers of soil degradation and the loss of soil organic carbon. Few studies have evaluated the impact of the expansion of the agricultural frontier on soil microbial communities in the Gran Chaco region in South America; therefore, the objective of this study was to explore how soil microbial communities respond to land‐use changes in a semiarid region of Argentina. The land uses selected were total and selective clearing with livestock (TC‐livestock and SC‐livestock), total clearing with agriculture (TC‐agriculture), and an undisturbed site (R‐Chancaní). Our results suggest that microbial abundances were strongly influenced by seasonal changes. In both seasons, the lowest values of total microbial biomass were observed in TC‐agriculture and TC‐livestock. In the wet season, TC‐agriculture had the lowest fungal abundance, and both total clearing sites (TC‐livestock and TC‐agriculture) had higher bacterial abundance than the other sites. Our data also showed that the Shannon and richness indices were highest at the farming sites, indicating a similar tendency in the diversity indexes in both dry and wet seasons. According to Pearson correlation analysis, humic substance (HS) content was a key driver influencing soil microbial communities, demonstrating that high HS content may significantly increase bacteria, fungi, and total phospholipid fatty acids. Microbial composition highly depended on seasonal changes. Overall, our results suggest that land‐use change altered microbial community structure and bacterial diversity, and that HS content played a crucial role in driving changes in soil microbial composition.

Service-Learning in Higher Education and Prosocial Identity Formation

For most nonprofits, their effectiveness, sustainability, and survival all depend on the willingness of individuals to behave in prosocial ways, for example, by giving time, money, and/or resources to various organizations and causes. Scholars have, therefore, long sought to identify predictors of prosocial behaviors; and, one consistently significant variable in this quest has been prosocial role identity. Indeed, the strength of this identity, studies have shown, positively predicts participation in a variety of prosocial activities. Despite this significance, research on service-learning, a widely utilized pedagogical practice intended to prepare prosocially active and engaged citizens, has been largely disconnected from the literature on identity motivated behavior. Yet, this literature provides a strong conceptual foundation for understanding why, when, how, and for whom participation in service-learning will be associated with positive changes in prosocial identities—and, ultimately sustained participation in role-related prosocial behaviors. In this article, we connect these literatures and propose a model.
Chromatic Priority Queues

We investigate the problem of implementing a priority queue to be used in a parallel environment, where asynchronous processes have access to a shared memory. Chromatic trees are a generalization of red-black trees appropriate for applications in such an environment, and it turns out that an appropriate priority queue can be obtained via minor modifications of chromatic trees. As opposed to earlier proposals, our deletemin operation is worst-case constant time, and insert is carried out as a fast search and constant time update, followed by an amortized constant number of rebalancing operations, which can be performed later by other processes, one at a time. If a general delete is desired, it can be implemented as a fast search and constant time update, followed by an amortized constant number of rebalancing operations, which again can be performed later by other processes, one at time. The amortization results here extend the results previously obtained for chromatic search trees. Since our proposal differs from previous work in that the processes doing updates need not have an exclusive lock on the root at any point, the number of processes which can work on the structure at any one time is not limited by the height of the tree. In fact, parallelism of the order the size of the tree is possible. The results proven in this paper show that congestion is unlikely to be a problem with a chromatic priority queue. We also present some heuristics which can be used if one wishes to even further reduce the probability of any problem due to congestion. As always, when working in an asynchronous environment, a locking scheme is required. We have included one possible locking scheme, specifically tuned to this application.
Accrual-based and cash-based earnings management in Algeria: substitution or complementary

Abstract Managers are often employed many alternatives for earnings management following their objectives or the financial reporting objectives; the commonly used are the accrual-based and cash-based earnings management. The literature reveals that managers adopt the two strategies in different ways, suggesting a mixed relationship between them. Hence, this study investigates the relationship between the two strategies of earnings management in Algeria, whether it is a substitute or complementary. The study included 30 Algerian companies during 2011-2019, so a total of 270 firm-year observations were employed. Accrual-based earnings management was measured through the modified-Jones model, while cash-based earnings management was measured through the abnormal cash flows model. According to the results, Algerian companies engage more in accrual-based earnings management and employ the two strategies as substitutes, which explains the strong and negative effect of accrual-based on cash-based earnings management. We argue that companies engage first in accrual-based earnings management, and then they shift towards cash-based earnings management due to auditors’ scrutiny. Furthermore, we found a positive and a medium effect of return on equity on cash-based earnings management, which reflects the managers’ desire to adjust operating cash flows consistent with the reported earnings. Finally, the results indicated that company ownership, company listing, and the nature of financial statements do not affect cash-based earnings management.
Structural dynamic properties of stiffened composite plates with embedded multi-layered viscoelastic damping membranes

Abstract Aiming at optimizing stiffened composite structures with embedded multi-layered viscoelastic damping membranes, we developed a dynamic analytical model based on the first-order shear deformation theory, in which the vibration equations were derived from both the modulus theory and the composite material mechanics theory. The theoretical solution that satisfied the displacement boundary conditions was obtained by employing the Navier method. Results were simulated by the finite element method to verify correctness of the dynamic analytical model. In addition, the effects of structural parameters on dynamic performance (including first-order natural frequency and modal loss factor) were studied using the developed model.
Shedding Light on Continuous Water Monitoring

This article discusses an online water quality monitoring system installed by the Wichita (Kansas) Water Utilities District. It consists of a number of online chemical monitors that are linked to remote communications for the detection of abnormal water quality shifts. Continuous chloramine monitoring units were fitted inline just prior to the first customer distribution point to ensure satisfactory residual disinfection. Online turbidity monitoring systems were also installed at each of the utility's 14 filtering points to provide real‐time filter‐efficiency data. The article discusses the technology involved in the JMAR BioSentry® water monitoring system that the Wichita Water Utilities District installed at two locations in its water distribution system. The system uses multi‐angle light scattering (MALS) to detect and classify microorganisms through continuous slip‐stream analysis. The MALS principle provides for the generation of a unique, species‐specific, light‐scattering pattern when a microorganism passes through the flow cell laser beam.
Comparison Between McCoy Laryngoscope and C-MAC Video Laryngoscope in Anticipated Difficult Airway: A Prospective Randomised Study

Objective: Prolonged laryngoscopy and failure to intubate are associated with increased morbidity and mortality. Need to improve glottic visualisation and ease of intubation has led to the introduction of various types of laryngoscopes. This study compares the effectiveness of C-MAC video laryngoscope (VL) with McCoy laryngoscope in patients with an anticipated difficult airway. Methods: This prospective randomised single-blinded single-centre study included patients with modified Mallampati grades 3 and 4, divided into two groups I and II of 65 patients each. Group I was intubated using C-MAC and group II with McCoy Laryngoscope. Modified Cormack Lehane grade of visualisation, time to intubate, intubation difficulty scale score and complications were recorded. Results: C-MAC VL provides a higher proportion of modified Cormack Lehane grade I visualisation (63% vs 35.3, p=0.0017), the lesser median time of intubation in seconds (15 vs 18, p=0.0007) and significantly lesser median intubation difficulty score (0 vs 3) when compared to McCoy. Conclusions: C-MAC VL provided better visualisation of glottis and easier tracheal intubation that too in a significantly lesser time. We conclude and recommend the use of C-MAC VL over McCoy for endotracheal intubation in patients with predicted difficult airways, especially in modified Mallampati grades 3 and 4.
Analisis Resiko Kegagalan Proses Kain jadi Polyester Menggunakan Metode FMEA pada PT XYZ Karawang

Proper quality control and clear stages and provide innovation in preventing and solving problems faced by the company. PT. XYZ Karawang is a textile industry company that produces polyester and cotton fabrics. In fact, this company still finds products with non-standard quality. From previous research data, the number of defects in polyester fabric tends to be quite high and does not comply with the standard, which exceeds the 2% set by the company. Meanwhile, the average product defect is 7,412 meters, about 5.4% of the total production each month is greater than cotton cloth. Therefore, the problem that arises is from polyester fabric which results in loss of cost of goods based on defects. FMEA is a technique used to identify the presence or potential of failures or problems in the design, process or structure of a sistem service before they occur, to prevent unwanted incidents and protect employees from occupational accidents and diseases by taking the necessary action. failures in the analyzed sistem are identified by FMEA, which enables the decision maker to take the necessary risk reduction actions. The purpose of this study is to analyze the failure modes that cause product defects using the FMEA method. The results of the research conducted based on the Risk Priority Number (RPN) there are 11 failure modes which are assumed to be the higher the failure mode RPN, the greater the risk for product failure and low quality. Of the 11 failure modes, the highest RPN value was 378, namely incomplete drug dissolution and the lowest was 27 with failure in the drug storage area. The factors that cause color spot defects on polyester fabrics are humans, raw materials, machines, methods used and the environment. In conclusion, the risk of failure in this study as a priority in the proposed improvement at the company PT. XYZ Karawang. Suggestions for improvement are given to the company as a whole to pay more attention to the factors causing the problem of fabric defects and as material for consideration in the company.
Flash Pyrolysis Experiment on Albizia odoratissima Biomass under Different Operating Conditions: A Comparative Study on Bio-Oil, Biochar, and Noncondensable Gas Products

This study deals with the flash pyrolysis of Albizia odoratissima biomass wastes at different temperature, sweep gas flow rate, and heating rate in a fluidized bed reactor. In the first phase of the experimental work, the effect of temperature (350–550°C) on product yield was analyzed, the second and third phases of the work were to analyze the effect of sweeping gas (N2), flow rate (1.25–2.25 m3/hr), and heating rate (20–40°C/min). The experimental works were carried out to get maximum bio-oil production. The experimental results demonstrated that the maximum yield of bio-oil was obtained at a temperature of 450°C, N2 flow rate of 1.75 m3/hr, and heating rate of 30°C/min. Temperature was found to be the crucial factor rather than sweep gas flow rate in the product distribution. Fourier transform infrared spectroscopy (FT-IR), gas chromatography mass spectroscopy (GC-MS), and elemental analysis were done on the obtained bio-oil, biochar, and noncondensable gas products. The heating value of the bio-oil and biochar was identified as 18.15 and 23.47 MJ/kg, respectively. The chemical analysis of the bio-oil showed that the oil is a mixture of phenol and oxygenated elements. The gas analyses showed that hydrogen and carbon dioxide were dominant, followed by carbon monoxide and methane.

REMARKS ON HARMAN AND KULKARNI'S "RELIABLE REASONING"

Reliable Reasoning is a simple, accessible, beautifully explained introduction to Vapnik and Chervonenkis’s statistical learning theory. It includes a modest discussion of the application of the theory to the philosophy of induction; the purpose of these remarks is to say something more. 1. A Patient Pessimist’s Guide to Induction Philosophical Learning Theory Vapnik and Chervonenkis’s statistical learning theory may be compared to formal learning theory, familiar to philosophers from the work of Putnam (1963) and Kelly (1996). There are significant technical differences between the two theories, but considered as philosophical frameworks for thinking about inductive reasoning, they have much in common. I will say that they are both—in their epistemological incarnations—species of philosophical learning theory . The programmatic goal of formal learning theory is to investigate methods for learning from experience that are guaranteed to converge on the truth. (or at least guaranteed to come as close as possible) under some given set of circumstances. If you have a method that is sure to converge, the thought goes, then provided that the particular circumstances within which the guarantee is offered actually hold, you are sure to find the truth—eventually. The problem of induction is in that case solved. Or at least, a problem of induction is solved, since different methods may be recommended in different circumstances. Statistical learning theory takes a similar approach; the most important difference for philosophical purposes is that, assuming as it does that we live in an inherently stochastic world, it does not pursue convergence per se but a kind (or several kinds) of probabilistic convergence. Rather than providing a guarantee of convergence on the truth, it
Overview of methods of reverse engineering of gene regulatory networks: Boolean and Bayesian networks

Reverse engineering of gene regulatory networks is an intensively stu- died topic in Systems Biology as it reconstructs regulatory interactions between all genes in the genome in the most complete form. The extre- me computational complexity of this problem and lack of thorough reviews on reconstruction methods of gene regulatory network is a sig- nificant obstacle to further development of this area. In this article the two most common methods for modeling gene regulatory networks are surveyed: Boolean and Bayesian networks. The mathematical descrip- tion of each method is given, as well as several algorithmic approaches to modeling gene networks using these methods; the complexity of al- gorithms and the problems that arise during its implementation are also noted.
