Abstract
The theory of the responsibility to protect was approved in 2005 in the output document of the United Nations Summit (A/RES/60/1) and in 2011, it was included in the Security Council Resolution 1973 regarding military intervention in Libya. The theory of the responsibility to protect implies the commitment of the international community to end the worst forms of violence and crime in humanitarian crises and internal armed conflicts. This article by using the qualitative method and document-library sources, books, articles and reports and internet notes, dealing with NATO's military intervention in Libya in 2011, which led to airstrikes, the creation of a no-fly zone, and ultimately the change of Muammar Gaddafi's regime, criticizes its application in Libya.The findings of the article show that although the theory tries to fill the gap between the former obligations of UN member states under international humanitarian law and human rights with this reality that the human population facing the threat of genocide, crimes against humanity, ethnic cleansing and crimes against humanity must be supported, France, the United States and NATO have exploited the 1973 resolution for their political-military goals and have caused the stoppage of the development of the theory and the skepticism of the international community towards the goals and intentions of the world powers in the application of the theory and as a result of the design of the new approach of responsibility during support.

Abstract
Background: Today a large number of bacterial amylases are available commercially in industry. The goal of the present study was purification and biochemical characterization of an extracellular thermostable alkaline α-amylase from the novel moderately halophilic, Bacillus persicus
from the Aran-Bidgol, Iran.
Methods
: Purification of enzyme, was carried out by acetone precipitation, ultrafiltration and Q-Sepharose cation exchange chromatography.
Results
: The purified native enzyme showed a molecular mass of 53 kDa composed of a monomer by SDS–PAGE. The optimum pH, temperature and NaCl concentration were 10, 45 ∘C and 0.85 M respectively. It retained 50% of activity at 1.25 M NaCl and about 73% of activity at highly alkaline pH of 10.5, therefore it was a moderately halophilic and also can activate by divalent metal ions especially Ca2+ and Mg2+. The apparent values of Km and Vmax were obtained 1.053 mg/ml and 356μ/min respectively.
Conclusion
: In the present study we report the purification and characterization of a moderately halophilic α-amylase from a newly isolated Bacillus persicus. The purified enzyme shows interesting properties useful for industrial and biotechnological applications. The molecular cloning and structural studies of this α-amylase are in progress in our laboratory.

Abstract
Aims: Psychological and emotional consequences of chronic low back pain (CLBP) often include anxiety, depression, emotional distress, and reduced quality of life, which can further exacerbate the perception of pain. This study aimed to evaluate the effectiveness of Acceptance and Commitment Therapy (ACT) on pain perception, post-traumatic stress disorder (PTSD), and emotional inhibition in patients with CLBP.
Method and Materials: The study utilized a quasi-experimental pre-test/post-test design with a control group involving 36 patients with CLBP from clinics in Qazvin in 2024. Participants were purposively selected and randomly assigned to either the intervention group (n=18) or the control group (n=18). The intervention group participated in eight 90-minute sessions of ACT, while the control group received no intervention. Data were collected using the McGill Pain Questionnaire, the Post-Traumatic Stress Disorder Scale, and the Emotional Inhibition Scale. The data were analyzed using MANCOVA in SPSS-27.
Findings: The results demonstrated that ACT significantly decreases pain perception (F=68.67), PTSD (F=21.39), verbal inhibition (F=64.86), timidity (F=66.08), disguise of feelings (F=67.81), and self-control (F=55.23) in individuals with CLBP (P< 0.001).
Conclusion: This study demonstrates that ACT not only alleviates the physical experience of CLBP but also effectively addresses the psychological barriers, such as PTSD and emotional inhibition, that amplify the condition. By fostering psychological flexibility, ACT offers a holistic approach to improving both the emotional well-being and pain management of CLBP patients.

Abstract
In the present study, properties of unsteady blood flow through an stenosed artery is investigated. The study has a tapered artery stenosed and asymmetric elastic walls is considered. The flow of blood is assumed to be incompressible, laminar and fully developed. To consider the effect of suspended particles in the blood, fluid model is used to describe micropolar Eringen. Governing equations are extracted and Mild stenosis approximation is applied to simplify. Also, an suitable converted is applied to momentum equations, initial and boundary conditions, the cosine shape mesh grid to regular mesh grid by utilizing suitable transformation. Non-slip boundary condition equations using finite difference method is solved numerically. To investigate the graphical shapes in the study, the effect of parameters related to flow and tapered angle has been the matter of into rest to investigate the Axial and rotational velocity profiles, the volumetric flow rate, Wall shear stress and the resistance to flow. Characteristics of elastic and non-elastic artery are compared and the results confirm the importance of elastic assumed artery. To confirm the accuracy results, these are compared the results of previous literature.

Abstract
The control pests and diseases is considered one of the most important operations of Citrus in the protection stage. Today, a lot of research has been done in various fields of agriculture, including the diagnosis of plant pests and diseases by using machine vision methods. One of the problems that reduce the accuracy of the machine for detecting pests in farm conditions is the presence of adverse factors such as shade and changes in light intensity at different times of the day. In this study, in order to find the appropriate light intensity at different times of the day and increase the brightness of the shady parts of the trees, lighting by a lamp at the imaging site has been used. For detect pest-infected trees (in this snail study) has been used to Deep learning method which has been studied and evaluated by various optimization algorithms such as RMSProp, Adam and SGDm. To evaluate and test the algorithm used, 8000 images were examined in 9 farm conditions and one laboratory state In farm conditions, the lowest detection accuracy of algorithms with 64.32% related to imaging in cloudy days with light intensity of 350 to 700 lux was obtained using RMSProp algorithm, which Detection accuracy was improved up to 95.25% using SGDm algorithm by creating a light intensity controlled by a lamp (approximately 9000 lux). In laboratory conditions where the images were prepared in a controlled environment with constant light intensity, the detection accuracy was Obtained 98.73% with SGDm algorithm.
