Synthesis of waveguide antenna arrays using the coupling matrix approach

With the rapid development in communication systems recently, improvements in components of the systems such as antennas and bandpass filters are continuously required to provide improved performance. High gain, wide bandwidth, and small size are the properties of antennas which are demanded in many modern applications, and achieving these simultaneously is a challenge. This thesis presents a new design approach to address this challenge. The coupling matrix is an approach used to represent the circuits made of coupled resonators such as filters and multiplexers. The approach has been utilised here to integrate a single resonator-based antenna with an n\(^t\)\(^h\) order filter. The integrated component is capable of providing a controllable bandwidth and introduces the filtering functionality. The approach is further developed in order to integrate bandpass filters with N×N resonator-based antenna arrays. This is to increase the gain of the array as well. Six novel components have been fabricated for the purpose of validation. This thesis also looks at a 300 GHz communication system which is proposed at The University of Birmingham with the objective to build a 10 metre indoor communication link. A 300 GHz (8×8) waveguide antenna array has been designed and fabricated for the system.

This article introduces PMOTO, a quick strategic and low-cost appraisal tool to identify a short-list of the most promising transport policies to mitigate the adverse impact of motorcycle usage on the city environment. Hanoi and Ho Chi Minh City, Vietnam, were selected as test cases for PMOTO with the same set of policy scenarios built on policy inputs such as tax, charges, fuel efficiency, emission costs, demand management, road-based travel, parking fees and public transport services. The relative merits of different policy options will be analysed and compared in each city and between the two cities.
Adolescents’ Perceptions of Sibling Caregiving

The purpose of the current study is to examine adolescents’ perspectives of sibling caregiving and how sibling caregiving is associated with adolescent development and family relationships. Using role theory as a framework, focus group data were collected from 13 primarily white (n = 10) female (n = 9) adolescents in a suburban midwestern city and inductive thematic analysis was conducted. Overall, our findings revealed that sibling caregiving is an important part of adolescents’ lives and may have important links to adolescent development and family relationships. It is important to note, however, that while these findings are not without limitations (i.e., lack generalizability) due to sample size and characteristic (predominately female and white), the examination of adolescent’s perspectives is an important avenue as we highlight the multidimensional nature of sibling caregiving, and the influence that sibling caregiving may have on adolescents’ development and family relationships within this sample.
Baccaurea Lour. (Phyllanthaceae Martinov - Malpighiales), underutilized plant from Riau, Indonesia and its phytochemical study

Abstract. Sofiyanti N, Fitmawati, Isda MN, Agesti ARA, Sari M, Pranata S. 2022. Baccaurea Lour. (Phyllanthaceae Martinov-Malpighiales), underutilized plant from Riau, Indonesia and its phytochemical study. Biodiversitas 23: 937-946. Baccaurea (Phyllantaceae) is one of underutilized plants in Riau Province, Indonesia. Our finding in some districts shows the variation of morphological characters of Baccaurea members. However, there is no detailed morphological study of these genera reported from this province. This study aimed to identify Baccaurea species from Riau and characterized their morphology, as well as, phytochemical contents. The specimens were collected from the field, documented and observed in detail their morphological characters. Phytochemical screening had been conducted using qualitative tests of a total of six secondary metabolites (alkaloid, terpenoid, steroid, tannin, flavonoid and saponin). A total of seven Baccaurea species were identified in this study. The main characteristic that can be used to distinguish each species are leaf characteristics (venation, size and shape), floral pattern and fruit characters. The phytochemical contents vary among the examined Baccaurea. Steroid and tannin are absent from all of examined specimens. Terpenoid is commonly found in all fruit parts of all specimens. The result of this study provides the first detailed morphological record as well as phytochemical data of Baccaurea from Riau.
Monitoring rice lodging grade via Sentinel-2A images based on change vector analysis

ABSTRACT Lodging stress influences the yield, quality, and mechanical harvesting ability of rice (Oryza sativa L.). It is of great significance for the quantitative and objective evaluation of rice yield loss to obtain the rice lodging distribution and grade information rapidly and nondestructively. The purpose of this paper was to establish a remote sensing monitoring method for the grade of rice lodging based on change vector analysis via Sentinel-2A images before and after lodging. Taking the lodging ratio (LR) of rice in the parcel as the characterization index, the changes in spectral reflectance and vegetation index of the rice canopy under different lodging grade stresses were analyzed. A 7-dimensional space vector was composed of a canopy spectral reflectance and vegetation index. A new angle vector was formed by the angle between each vector object and the axis of the canopy spectrum (vegetation index). Based on the difference in feature vectors before and after lodging, a lodging grade monitoring model based on rice parcels was constructed, and the accuracy of the model was verified using field observations. The results showed that the spectral reflectance of the rice canopy after lodging increased with the increase in lodging stress. The difference in vegetation index before and after lodging increased with the increase in lodging severity. Based on the change in the magnitude of the canopy spectral reflectance and its angle vector, and the vegetation index and its angle vector, the R 2 of the rice lodging model was 0.66, 0.66, 0.60, and 0.59, respectively, and the RMSE values were 21.03%, 20.37%, 22.13%, and 22.84%, respectively. Therefore, the accuracy of the model constructed using the vegetation index was the highest. The canopy spectral reflectance and difference in the vegetation index of rice changed regularly with lodging grade stress. The model based on the change magnitude of the vegetation index could effectively realize remote sensing monitoring of the grade of rice lodging in Wuchang.
A novel wearable electronic device for treating neurogenic detrusor overactivity by conditional neuromodulation

Urinary incontinence is the involuntary leakage of urine and affects one in twenty of the population across all ages leading to poor quality of life and can be very high cost to the nation. It is possible to reduce these costs by accurate diagnosis and appropriate management of the condition. Urinary incontinence is often associated with an overactive bladder or urethral sphincter weakness, or both as a result of interrupting the pathway to nervous communication between the brain and the bladder leading to uncoordinated activity in the lower urinary tract. Treatment options for overactive bladder include antimuscarinic drugs and implanted electrical stimulators. However these drugs have intolerable side effects, while implanting a stimulator is a surgical procedure which is associated with degree of risk and becomes ineffective due to habituation to the continuous stimulation. The aim of the research was to develop a novel wearable anal device designed to deliver conditional neuromodulation. The device detects the electromyography activity in the lower urinary tract, and provides the transrectal stimulation to the Pudendal nerve when required, in order to suppress the bladder contractions while contracting the urethral sphincters. The clinical study included designing and manufacturing patient compatible model and conducting a clinical study to measure the safety and the efficacy of the device. Electronics circuit design included amplifier, signal processing system and constant current stimulator based on the specification derived from the clinical study and finally focused on optimisation of the device electrodes for improving stimulating parameters.
Occurrence of soil-inhabiting entomopathogenic fungi within a conventional and organic farm and their virulence against Spodoptera litura

Abstract. Afandhi A, Choliq FA, Fernando I, Marpaung YMAN, Setiawan Y. 2022. Occurrence of soil-inhabiting entomopathogenic fungi within a conventional and organic farm and their virulence against Spodoptera litura. Biodiversitas 23: 1172-1180. Naturally occurring entomopathogenic fungi (EPF) are important components in agroecosystems as they serve as biocontrol agents of insect and mite pests. However, some cultivation practices may have deleterious effects on EPF. In this study, the occurrence of soil-inhabiting EPF was investigated between a conventional and organic farm. EPF was baited using Tenebrio molitor larvae, and their virulence was tested against Spodoptera litura larvae. The results showed a higher occurrence of EPF in the organic farm than the conventional farm, with Aspergillus sp. , Beauveria sp. , and Gliocladium sp. were exclusively found in organic soils. Among the twenty-five EPF isolates obtained, only four isolates were avirulent against S. litura larvae. Isolates belonging to Beauveria, Metarhizium, and Paecilomyces genera caused high mortality of S. litura larvae ranging from 40 to 65%. There was a significant positive relationship between the conidial viability of EPF and larval mortality. Since virulent isolates were found in conventional soils, efforts in preserving EPF prevalence are needed through the implementation of appropriate cultivation practices. The synthetic agrochemicals exclusion, organic fertilizers application, and crop rotation practiced in the organic farm should be integrated into any other agroecosystems as a form of conservation biological control strategies to strengthen the pest control service provided by EPF.
A comprehensive approach to model abiotic resource provision capability in the context of sustainable development

Throughout history, scarcity of abiotic resources has been an important issue, as access to resources is a prerequisite for the development of complex societies. In the context of continued high levels of resource consumption, growing world population, as well as rapid industrialization of countries like China or India, increasing concern over abiotic resource availability has been raised. Accessibility to resource to satisfy current needs of society and preserving resources for future generations and potential future uses is relevant for sustainable development. But how can global material needs be satisfied sustainably and which aspects need to be considered? This Chapter provides an introduction to the field of abiotic resource availability and research needs are identified. The evaluation and assessment of resource availability in the context of sustainable product development is the central point of this dissertation. Whether resources will be at hand for material requirements of products depends upon physical availability in the environment and economic, environmental and social developments throughout the entire world. Scarcity of resources, whether absolute if caused by depletion of available stocks, or effective if caused by (temporary) interruptions in supply, need to be closely monitored to sustain resource availability today and in the future. In a comprehensive literature review, existing models for the assessment of resource availability on a product-level are evaluated. So far, life cycle assessment (LCA) is the method of choice for quantifying impacts on resource availability and several approaches exist. However, available methodologies and models to address resource availability do not live up to the challenge of comprehensively addressing the problem. Availability of resources is seldom considered for product evaluations and commonly agreed indicators for identifying scarcity associated with different resources are missing. To understand and “uncover” constraints and risks associated with abiotic resource provision for product systems the analysis needs to go beyond the assessment of single indicators and consider the complexity of sustainable development. Instead of addressing resource availability in an environmental context, a comprehensive approach and according methodologies need to be developed towards the assessment of all dimensions of sustainability. By including environmental, economic and social constraints into the analysis of resource availability a goal and solution oriented decision support methodology will be develop in this dissertation, facilitating material choices on a product level and complementing existing approaches.

Improving browser security policies

Browsers are rapidly improving as a platform for compelling, interactive applications. Unfortunately, the web security model is still not fully understood. Existing browser security policies were designed in an era where Web users only interacted with one principal at a time, but modern browsers often have many tabs open simultaneously, and these tabs often contain third-party content from multiple sources. In this thesis, we articulate the "web attacker" threat model, which captures these multi-principal interactions, and use this threat model to demonstrate a variety of attacks on existing browser security policies. These attacks can be used to bypass firewalls, intercept private data, and forge unauthorized transactions. We collaborate with browser and plug-in vendors to deploy industry-wide solutions. We also show how web advertising networks, a powerful weapon in the hands of the web attacker, can be equally powerful to security researchers as a platform for research and analysis.
A 0.6-V 5.2 GHz Folded Cascode LNA with Transformer-feedback Technique for Ultra Low Power Applications

Abstract This paper presents a 5.2 GHz ultra low power folded cascade low-noise amplifier at low-voltage operation. By utilizing a forward body bias and folded cascade technique, the proposed LNA can operate at a reduced supply voltage and power consumption. In addition, reactive (transformer) feed-back is adopted to further enhance the LNA gain. The proposed LNA delivers a remarkable gain of 15.3 dB with a noise figure of 0.8 dB, while consuming only 0.8 mW dc power from a 0.6-V supply voltage at 5.2 GHz, the simulated Pin-1dB and IIP3 are −22 and −10.34 dBm, respectively. The results indicate that this LNA is full suitable for the ultra low power application.

A Novel BCRLS-BP-EKF Method for the State of Charge Estimation of Lithium-ion Batteries

State-of-charge of lithium-ion batteries is one significant state parameter for battery management system monitoring. To accurately estimate the state-of-charge in real time, a novel BCRLS-BP-EKF method is proposed innovatively. Based on FFRLS algorithm, bias compensation is added to better capture the real-time operating characteristics of the system. To modify the model error of EKF algorithm, BP neural network is introduced, which has powerful nonlinear mapping and self-learning ability. The estimation error of EKF can be corrected by its learning and training relevant parameters that affect the estimation value of filtering. The data of different complex working conditions are used to verify the feasibility and rationality of the proposed algorithm by building a second-order RC equivalent circuit model. The results show that the root mean square error of the novel BCRLS-BP-EKF method under HPPC and BBDST operating condition can be controlled within 0.11% and 1.41% in state-of-charge estimation, which verifies that the proposed algorithm in this research has high precision and convergence characteristics. The novel BCRLS-BP-EKF method lays a theoretical foundation for accurate state estimation of lithiumion batteries, which will effectively improve the security and reliability of electric vehicles.
The potential of copper-resistant bacteria Acinetobacter sp. strain CN5 in decolorizing dyes

Abstract. Irawati W, Pinontoan R, Mouretta B, Yuwono T. 2021. The potential of copper-resistant bacteria Acinetobacter sp. strain CN5 in decolorizing dyes. Biodiversitas 23: 680-686. Bacteria with multi-resistance to copper and dyes may be employed in bioremediation of copper and dye waste more effectively than physical or chemical remediation. This study aims at determining the effect of the addition of various textile dyes and copper on the growth of Acinetobacter sp. CN5 and its ability to decolorize dyes. The dye resistance test was carried out by inoculating bacterial isolates into Luria Bertani media containing 50, 100, 150, 200, 250, 300, 350, 400, 450, and 500 ppm dyes. The twelve dyes used in the test were methylene blue, malachite green, congo red, mordant orange, reactive black, direct yellow, basic fuchsine, reactive orange, dispersion orange, remazol red, wantex yellow, and wantex red. The decolorization activity was analyzed by spectrophotometry at a 300-900 nm wavelength. The study results demonstrated that bacteria thrived in media containing 50 ppm of all dyes, except malachite green dye. Acinetobacter sp. CN5 was found to be resistant to up to 500 ppm methylene blue, basic fuchsine, and wantex red and resistant to congo red at 450 ppm. Acinetobacter sp. CN5 was also able to decolorize methylene blue, congo red, basic fuchsine, and red wantex by 57.64%, 53.17%, 91.37%, and 67.50%, respectively. The addition of 5 mM CuSO4 to the medium increased the ability of Acinetobacter sp. CN5 to decolorize the congo red from 57.64% to 82.58%.

Corporate brand management: past, present and future

There is a paradigm shift from Product Brand Management towards Corporate Brand Management. One of the reasons for its growing popularity is its strategic role and importance in gaining competitive advantage and in strategic management decisions. A major difference between product and corporate branding is that the latter requires greater focus within the organization. One of the implications of this is that corporate marketing necessitates not only a planning perspective which addresses the matching of external opportunities with core competencies, but also considers the integration of internal activities to ensure cohesion and therefore consistency in delivery. This paper presents differing perspectives on corporate brand management and presents a new approach by describing a model for managing corporate brands.
Distribution, occurrence and molecular characterization of Bacillus related species isolated from different soil in Basrah Province, Iraq

Abstract. Alyousif NA. 2021. Distribution, occurrence and molecular characterization of Bacillus related species isolated from different soil in Basrah Province, Iraq. Biodiversitas 23: 679-686. Bacillus related species are widely predominant in various environments such as soil with diverse environmental conditions. These bacteria are one of the most explored groups of bacteria in industrial biotechnology due to their enzymes. The present study was aimed to isolate, screen and determine the distribution of Bacillus related species from soil samples. The total Bacillus related species counts in one gram of each soil sample ranged between 3.2 X 103 cfu/g and 4 X 103 cfu/g. A total of 43 isolates with different morphologies were isolated from the soil samples out of ten different habitats and the number of morphotypes recovered from each habitat varied from 2 to 7. The molecular identification of isolates by PCR technique and sequencing of 16S rDNA gene indicated that 43 isolates belonged to the genera Bacillus, Cytobacillus, Priestia and Peribacillus. The species Bacillus licheniformis and Bacillus subtilis were the most distributed species in the habitats. The bacterial isolates were showed 100% similarity, except 8 isolates were showed 99% similarity were identified as new strains and their sequences were deposited at the National Center for Biotechnical Information (NCBI). The phylogenetic tree was constructed by MEGA X software based on 16S rDNA gene sequences of Bacillus related species to evaluate their close relationship and evolution. The study revealed the higher diversity and distribution of Bacillus related species in the soil samples and the molecular technique was the best method for identifying Bacillus related species.
Phenolic compounds from Thymus vulgaris, Artemisia annua extracts and pure Thymol were tested against twenty Pseudomonas spp. strains for antibacterial and anti-biofilm activities

The widespread use of broad-spectrum antibiotics has resulted in antibiotic resistance for many human bacterial infections, making multi-drug resistance a significant challenge in the treatment of infectious diseases. The antibacterial impact of phenolic plant extracts has been studied in new and different ways. The phenolic extract of Thymus vulgaris, Artemisia annua and pure thymol were used to study bacterial biofilm formation. In addition, the experiments were carried out to determine the lowest inhibitory concentrations in order to evaluate the antibacterial impact (MICs) against 20 isolations of Pseudomonas species. In this report, the plant extract was analyzed by HPLC techniques to determine the Thymol value. Although the Thymus vulgaris and Artemisia annua phenolic plant extracts and pure thymol concentrations (50, 25, 12.5, 6.25, 3.125, 1.250 and 0.006 mg/ml) (W/V)) were used through antibiotic and biofilm inhibition assay. The best results of MICs of T. vulgaris, A. annua extract and pure Thymol against bacteria isolates were 5.000 mg/ml, 1.250 mg/ml and 0.006 mg/ml, respectively. Stimulatory, the effect of T. vulgaris, A. annua extract and pure Thymol on biofilm formation were gave 10 mg/ml, 5mg/ml and 0.006 mg/ml respectively.
