“…Theoretical discussion of such nuclei took place during many years, beginning with the work by R.H. Dalitz and R. Levi-Setti, [3] - [7], in parallel with experimental searches [8,9,10,2]. It has been noted first in [3] that the Lambda particle may act as additional glue for the nuclear matter, increasing the binding energy in comparison with nucleus having zero strangeness.…”

The binding energies of neutron rich strangeness S = −1 hypernuclei are estimated in the chiral soliton approach using the bound state rigid oscillator version of the SU (3) quantization model. Additional binding of strange hypernuclei in comparison with nonstrange neutron rich nuclei takes place at not large values of atomic (baryon) numbers, A = B ≤∼ 10. This effect becomes stronger with increasing isospin of nuclides, and for "nuclear variant" of the model with rescaled Skyrme constant e. Total binding energies of 8 Λ He and recently discovered 6 Λ H satisfactorily agree with experimental data. Hypernuclei 7 Λ H, 9 Λ He are predicted to be bound stronger in comparison with their nonstrange analogues 7 H, 9 He; hypernuclei 10 Λ Li, 11 Λ Li, 12 Λ Be, 13 Λ Be etc. are bound stronger in the nuclear variant of the model. 1

“…HTML tags are available to prevent bots from stepping into confidential pages. If the user is determined to gain access to the data, then a trial is employed to resolve the CAPTCHA challenge and eventually gain access to the page but the computer programme (bot), may deny the access [14][15][16].…”

CAPTCHA is an acronym that stands for Completely Automated Public Turing Test to tell Computers and Humans Apart (CAPTCHA), it is a good example of an authentication system that can be used to determine the true identity of any user. It serves as a security measure to prevent an attack caused by web bots (automatic programs) during an online transaction. It can come as text-based or image-based depending on the project and the programmer. The usability and robustness, as well as level of security, provided each of the varies and call for the development of an improved system. Hence, this paper studied and improved two different CAPTCHA systems (the text-based CAPTCHA and image-based CAPTCHA). The textbased and image-based CAPTCHA were designed using JavaScript. Response time and solving time are the two metrics used to determine the effectiveness and efficiency of the two CAPTCHA systems. The inclusion of response time and solving time improved the shortfall of the usability and robustness of the existing system. The developed system was tested using 200 students from the Federal College of Animal Health and Production Technology. The results of each of the participants, for the two CAPTCHAs, were extracted from the database and subjected to analysis using SPSS. The result shows that textbased CAPTCHA has the lowest average solving time (21.3333 s) with a 47.8% success rate while image-based CAPTCHA has the highest average solving time was 23.5138 s with a 52.8% success rate. The average response time for the image-based CAPTCHA was 2.1855 s with a 37.9% success rate lower than the text-based CAPTCHA response time (3.5561 s) with a 62.1% success rate. This indicates that the text-based CAPTCHA is more effective in terms of usability tests while image-based CAPTCHA is more efficient in terms of system responsiveness and recommended for potential users.
