PEOPLE’S AGES AND THE EFFECTIVENESS OF USING ACTIVITIES IN THE BUILT ENVIRONMENT OF COMMERCIAL STREETS
Get PDFStreets are the most public of all city spaces and are utilised by all users. Therefore, activities are vital in persuading people to use the streets and in presenting the image of the city. The relation between people’s ages and the used activities of the commercial streets has declined due to the poor physical environments in the local context. Streets have become progressively unpleasant, unsuitable in terms of functions, and have also become a disagreeable environment. This represents the problem statement of this research. The objective of this paper is to examine the relationship between activities on commercial streets and the different age groups of the users. This study focuses on the local context of Mawlawi Street, which is one of the major shopping streets in Sulaymaniyah city centre, Iraq. This paper used a quantitative methodology via a survey of users (n = 330). The data were analysed using frequency, mean value, percentage, and chi-square statistics. The results show that cultural activities were the most important for its users, while social activities were the least important, with businesses in the middle. The majority of the users were in the young-adults age category. The research gives a good overview of the types of activities which encourage high street usage, and which activities need to be improved or added
IFRS ADOPTION AND VALUE RELEVANCE OF ACCOUNTING INFORMATION OF LISTED INDUSTRIAL GOODS FIRMS IN NIGERIA
Get PDFThe study examines the effect of IFRS adoption on the value relevance of accounting information of six (6) out of thirteen (13) listed industrial goods firms in Nigeria for the period of fourteen years (2007-2020); seven (7) years before IFRS adoption and seven (7) years after IFRS adoption. Earnings per share (EPS), Book value per share (BVPS) and Dividend per share (DPS) constitute the independent variables and share price as the dependent variable. Ex-post facto research design was employed and multiple regression models as well as Ohlson (1995) price model were used to analysis the audited financial statement of the sample size. The result reveal that EPS is negatively and DPS is positively associated with share price and both are significant, while BVPS is insignificantly associated with share price in the pre-IFRS era. On the other hand, EPS has negative significant association with share price, while BVPS and DPS is having a positive and significant association with share price in the post-IFRS era. Therefore, it is concluded that the value relevance of accounting information has increase after the adoption of IFRS; this is supported by the R2of post-IFRS (51%) which is higher than the R2of pre-IFRS (30%
Body Language in Education and Effective Recommendations to Pre-Service Teachers in Classroom Management
Get PDFCommunication with people is achieved through words. While using words and body language in verbal communication, sign language is used with the deaf and dumb. Sending messages to others can be with our words, sometimes only with our body language. As educators teaching in different branches, we need words and body language to communicate with students influentially. Correct use of body language ensures that the message is conveyed to students more effectively and rapidly. In this study, pre-service teachers will be advised about the importance of body language, the experienced educators’ opinions about body language and its necessity in classroom management will be shared. According to experienced teachers, the correct use of body language facilitates the teachers’ class management skills. Hence, this article focuses primarily on why teachers should be good senders and receivers of nonverbal communication. The study was qualitative research, and a google-form interview technique was used. We demonstrated ten experienced teachers’ views from the researchers’ workplace about the significance of the usage of body language based on 3 open and 2 close ended questions

An Overview Of Current Developments In The Synthesis Of Carbon Nanotubes And Their Use In Medicinal Applications
Get PDFIn order to address problems associated with conventional drug therapy, such as limited drug solubility, poor biodistribution, lack of property, and unfavourable pharmacological medicine, new nanomaterials have been extensively investigated in recent years for drug delivery applications. Among them, carbon nanotubes (CNTs) are well known and rank among the most notable innovations in the field of nanotechnology because to their unique chemical science design, characteristics, and potential for usage in a variety of industries. CNTs are acknowledged as nano-architecture carbon allotropes with length-to-diameter ratios up to 1,000,000. CNTs frequently have single, double, or multiple walls and are square sheets of rolled graphene with SP2 coupling.The key characteristics of CNTs include their light weight, small size with a high aspect ratio, distinctive surface area, resilience, sensible tensile strength, and sensible conducting properties, which make them useful as fillers in a variety of materials including polymers, metallic surfaces, and ceramics. These cylindrical carbon molecules' potential uses in nanomedicine, nanotechnology, energy, textiles, actuators, sensors, composite materials, membranes, and capacitors have generated a great deal of enthusiasm in the pharmacy community. CNTs are refunctionalized or altered to hold payloads or interact with biological molecules since they are chemically inert and soluble in neither water nor other organic solvents. Due to their widespread use in medical applications such as the delivery of drugs, genes, and DNA as well as for biosensing, CNTs are best functionalized with proteins. They have the ability to cross membranes, transporting medicinal drugs, vaccinations, and nucleic acids deep inside the cell to previously unreachable locations. Numerous processes, such as flame synthesis, sol gel, silane solution, arc discharge, laser ablation, and chemical vapour deposition, have been devised to create nanotubes in significant numbers. The majority of the procedures used to purify CNTs include oxidation, acid treatment, annealing, sonication, chemical filtering, and functionalization techniques. High-purity purification methods must to be developed, though. These structures' striking advantages include their electrical, mechanical, optical, and chemical properties, which pave the way for potential future applications. This in-depth study focused on the synthesis, purification, functionalization, characteristics, advantages, applications, and most recent developments related to the use of CNTs for drug administration. The toxic effect of CNTs was also imparted in an extremely condensed form

The Status of Green Synthesis of Silver Nanoparticles Using Plant Extracts during Last Fifteen Years
Get PDFNanoparticles (NPs) are tiny particles with their dimensions ranging between1and100 nm. These are gaining cumulative attention owing to their vast use in different fields of applications. There are three main methods for synthesizing NPs; namely, physical, chemical and biological methods. Physical methods consume a lot of energy and time, require expensive vacuum systems and high temperatures and on top of all, they are not environmentally friendly. Chemical methods, in general, are expensive, increase the particle toxicity and perhaps harm human health and the environment. In addition, hazardous chemicals gather on the top of NPs and confine their applications. Therefore, green method is an alternative replacement to the traditional chemical and physical methods for synthesizing NPs. The existing phytochemicals, for instance in plant extracts, own a remarkably high ability for reducing metal ions within a short time comparing with other microorganisms, which require a longer incubation period. This study is concentrating on green synthesis of silver (Ag) NPs, owing to the significance of Ag NPs whose optical properties depend on their size and shape. In addition, Ag NPs possess numerous applications, especially in solar cells, water treatment and medicine. This review aims to highlight the remarkable growth of green synthesis of Ag NPs, in terms of publications, citations, active and productive researchers, targeting journals and the eminent countries in this regard. This review, also, is highlights the most utilized plants for producing Ag NPs in fourteen years; i.e., 2007-2021.This review, also, evaluating the most acceptable proposed mechanism for biosynthesizing Ag NPs using plant extracts. We believe that this review article will facilitate and brighten the road in front of researchers who want to initiate their study with the biosynthesis of Ag NPs from plant extracts
Multivariate discrimination of selected taxa of the Fabaceae family
Get PDFAbdulrahman MD. 2022. Multivariate discrimination of selected taxa of the Fabaceae family. Nusantara Bioscience 15: 227-232. Nigeria is among the most interesting and diversified countries globally regarding tropical vegetation and medicinal plants. The taxonomy of the Fabaceae family is not entirely clear, to organize species into manageable groups that are helpful for taxonomical, conservational, or pharmacognostic study. This study aimed to discriminate the leaves of Dialium guineense Willd., Detarium microcarpum Guill. & Perr, Tamarindus indica L, Acacia nilotica (L.) Willd. ex Delile, Abrus precatorius L., Senna occidentalis (L.) Link, Erythrina senegalensis DC. and Pterocarpus erinaceus Poir. based on the mineral elements contents coupled with multivariate analysis. Three samples of each wild-growing species were collected. Unsupervised multivariate analysis using SIMCA-P (V.14.1, Umetrics Sweden) was employed. Five model groups were formed based on their mineral element contents. The species were fully discriminated along the PC1, accounting for 39.3% of the variation. Evidence from this study showed that a combination of mineral element analysis and chemometrics yielded a powerful classification method. Taxonomic identification of plants through biological research combined with chemometrics is an excellent method for preventing the adulteration or consumption of plants with excessive contents or harmful ingredients. However, a mix of molecular and developmental datasets is still necessary to explicitly examine their connections
