The ever-increasing demand for paper and paper products and alarming rate of global population growth necessitates research into non-wood fibre to augment the popular wood fibres in short supply. Sida acuta obtained at two locations, samples collected from 3 areas per location. Samples of dimension 10 x 10 x 20 mm macerated in equal volumes of glacial acetic acid and 30% hydrogen peroxide at 80^oC in an oven. Twenty-five whole fibres in swollen condition were measured. Derivatives of fibre dimensions viz:  Runkel ratio, flexibility and slenderness were also evaluated. Pooled mean fibre length was 1.04mm, pooled fibre diameter was 25.02μm, pooled fibre lumen width was 14.69μm and fibre cell wall thickness was 5.17μm. Runkel ratio was 0.73, coefficient of suppleness (flexibility) was 60.05 while felting power (slenderness) was 42. Values obtained connote that S. acuta’s fibre morphology is good for pulping much more that its Runkel ratio (0.73) is less than 1, coefficient of suppleness (60.05) is greater than 50 and its felting power (42) is greater than 33. Specific Gravity ranged from 0.416–0.468. With reference to the above, S. acuta is fairly suitable for pulp and paper making.

The intersection of agriculture and cybersecurity has become a prominent research focus in recent years, driven by the rapid adoption of IoT (Internet of Things) and precision farming technologies. These technological innovations have revolutionized agricultural processes, enhancing efficiency and sustainability while introducing significant security risks. This study conducts a systematic literature review (SLR) to address key cybersecurity issues in agriculture, with a particular emphasis on IoT vulnerabilities and threats. Using Python-based text analysis techniques, the research automated the analysis of abstracts and full texts, enabling rapid filtering and thematic categorization of relevant studies. From an initial pool of 1,039 publications, 40 relevant studies were identified based on rigorous screening criteria. The thematic analysis revealed that 44.9% of the publications focus on IoT device vulnerabilities, 32.7% on agricultural cybersecurity challenges, and 22.4% on the security issues of Agriculture 4.0 and precision farming. Methodological analysis indicated that machine learning, simulation models, and case studies dominate the research landscape, while surveys and experimental studies appear less frequently. The findings highlight the critical importance of developing robust cybersecurity strategies and technologies in the agricultural sector, particularly to mitigate the risks posed by IoT devices.

This publication is intended to examine the close relationship between quality management and leadership and organization, highlighting the possibilities of increasing organizational efficiency in both industrial and non-industrial environments. During the systematic literature review, we examined the role of leadership, the closely related organizational culture, and quality management. The publication aims to explain how quality systems and frameworks, such as ISO and the EFQM model, support strategic planning and sustainability, thus providing direction for modern organizations. The research emphasizes the importance of digital transformation and knowledge management, and we have formulated the future research goals that can advance the productivity of organizations.

In the modern business landscape, branding goes beyond identifying products and services; it has become a crucial factor for corporate success. The leadership branding, and employer branding emerges as a key strategic tool in gaining competitive advantage, fostering loyalty, and enhancing engagement. Personal branding, as the conscious presentation of individual values and capabilities, supports leaders in strengthening credibility and trust. Leadership branding encapsulates a leader’s personality and style, serving as an inspiring example within the organization. Moreover, employer branding reflects the corporate culture and workplace values, making the organization attractive to talented employees. The aim of the study is to demonstrate how personal branding, including leadership branding and employer branding, can contribute to the more successful operation of a company, highlighting the synergy between the different levels of branding and their economic and social impacts.

Nowadays, the most common type of implant in dentistry is a partial tooth replacement, such as a crown, or a complete tooth replacement. Today, many manufacturers offer implants made of a wide variety of materials and designs. These restorations must meet strict standards, one of the most stringent being surface roughness. Since proper bone-to-implant contact only occurs with adequate surface roughness, several methods are used to achieve the correct value. After reviewing the results of experiments carried out by several research groups, it is concluded that the surface roughness, the shape of the implant fixation screw, the shape of the thread and the thread elevation used to achieve the desired roughness together determine the success of the implantation. The average surface roughness required for osseointegration is considered to be optimal for values between 1 and 100 µm. In most cases, the surface roughness of commercially available dental prostheses is Ra 1-2 µm, but this can be modified by various grinding, acid etching and polishing processes to suit the application. Acid etching is a common technique for roughness reduction, which is the most effective in reducing surface roughness of dental restorative materials (mostly titanium alloys), thus bringing the roughness within the desired range. The result of acid etching is influenced by the concentration of acid, the temperature of the acid bath and the time spent in the acid. The acid used for the surface treatment is important and is most commonly sulphuric acid, hydrochloric acid or hydrogen fluoride (HF) and combinations of these. The study shows that the most optimal results are obtained with HF. Replacements are nowadays largely made by additive manufacturing, which allows for customised replacements and, due to dimensional accuracy, reduces the time and cost of post-processing, i.e. the surface treatment can be used to achieve the desired surface roughness and size at the same time. As a result, newer materials are being used for clinical prostheses and surface treatment should be applicable to all materials. The most optimal solution is a combination of grit blasting and acid etching. With this technology, the surface roughness for all materials reaches the optimum value of 1-100 µm, sometimes 1-2 µm, but can be further reduced below 1 µm by polishing. The study investigates the role of surface roughness, the surface roughness should only be reduced up to a certain value, approximately 0.5 µm, as smooth surfaces have limited or no potential for osseointegration.
