العالم الالكتروني وأثره في نشر الفكر المتطرف "دراسة قانونية تحليلية مقارنة"
(2025-06-01) م.م مصطفى محمد منصور العبدلي
ان الفكر المتطرف يعد من اخطر انواع الارهاب، وكما انه يمثل ظاهرة عالمية مرتبطة بفكر الانسان اياً كان توجهه ومعتقده او مذهبه فهو يقوم بغلق فكره وقمع حريته الفكرية.
ساهم العالم الالكتروني بشكل كبير في انتشار الفكر المتطرف من خلال استخدام المواقع الالكترونية المختلفة خاصة التطرف الذي اتخذ من الاسلام غطاء له كالعصابات الداعشية والقاعدة ليبثوا افكارهم الظلامية عبر الشبكة العنكبوتية لتصل الى شرائح المجتمع بسرعة كبيرة.
ان كان من السهل مكافحة الفكر المتطرف في الواقع لأنه يكون مكشوف او يمكن التعرف عليه من خطاباته وتحركاته، عكس ما عليه الحال في الواقع الالكتروني الذي يحتاج الى تظافر الجهود لكبح وجوده والتضييق عليه لأنه يستخدم مواقع الكترونية كثيرة وغرف سرية مغلقة، بالتالي يقع على عاتق الحكومة وضع القوانين الرادعة وتفعيل الرقابة والتوعية المجتمعية والاجهزة الامنية للتصدي لهذا الخطر الكبير والحد من وجوده.
وعليه فإن سبب اختياري لهذا الموضوع ما هو الا من باب الحرص على المجتمع الدولي بشكل عام والمجتمع العراقي على وجه الخصوص الذي عانى الويلات من خطورة الفكر المتطرف.
من الصعب انهاء وجود هذا الفكر بالكامل في العالم الالكتروني الواسع ولكن لابد من العمل على تحجيم خطره باتخاذ خطوات جدية وحلول ناجعة.
ان ابرز ما توصلنا اليه في هذا البحث هو تعريف الفكر المتطرف واهم الدوافع التي تسبب في انتشاره ووضحنا المعالجات القانونية الممكنة على المستوى الدولي والوطني.
New molybdenum(VI) complexes with bidetantete (N,N), (N, S), and (S, S) ligands spectral characterization and theoretical calculations
(2025-05-25) Othman I. Alajrawy; Alaa Mh. EeSee
[MoO2(acac)(ATP)], [MoO2(4CPD)(ATP)], [MoO2(ATP)2], and [MoO2(ATP)(DTO)] are four new MO(VI) complexes have been synthesized, where (acac) is acetylacetone, (ATP) is 2-aminothiophenol, (4CPD) is 4-chloro-ophenylenediamine, and (DTO) is dithiooxamide. The complexes were characterized using a variety of spectral
techniques, such as mass spectroscopy, 1
H NMR, FT-IR, UV–Vis., and theoretical calculations. The FT-IR spectra
showed that the oxygen, nitrogen, and sulfur atoms coordinated the ligands with the MO(VI) ion. The mass
spectrum of each complex describes its mononuclear structure. The complexes are diamagnetic and have an
electrical configuration of d0
. The complexes’ lowest unoccupied molecular orbitals ranged in energy from
− 0.095 to − 0.260 a.u., while their highest occupied molecular orbitals ranged from − 0.347 to − 0.373 a.u.,
according to the computational results. The complexes were found to be softer and more soluble than the free
ligands. The prepared complexes feature distinct coordination environments around the MO(VI) ion, specifically:
(2O, N, S), (3N, S), (2N, 2S), and (N, 3S). This variation in the percentage of sulfur atoms surrounding the Mo(VI)
ion was intentionally designed based on Pearson’s Hard and Soft Acids and Bases theory. The comparatively
easier electronic transitions observed in the complexes, relative to the free ligands, suggest their potential for
future application in photocell research. For each complex, a distorted octahedral geometry was proposed based
on the calculated bond lengths and bond angles.
Cytotoxic evaluations, spectral characterizations and DFT theoretical calculations of new dioxidovanadium(V) complexes
(Mongolian Journal of Chemistry, 2025-05-26) Othman I. Alajrawy; Huda A. Hadi; Roaa S. Awad Al-Luhaib; Sarah S. Sabar
Two dioxidovanadium(V) complexes have been prepared with dinitrogen atoms donor (ophenylenediamine (OPD) and dithiooxamide (DTO)) ligands. The cytotoxicity studies of the
prepared complexes against the L20B cell line displays that they have moderate activity 15
against the L20B cell line. Then, the complexes were characterized by different spectral
techniques such as FT-IR, UV-Vis., mass, 1H-NMR spectroscopy, magnetic susceptibility,
and molar conductivity. Finally, the spectral data were compared with the data obtained by 18
the DFT theoretical calculations. The obtained spectroscopic data confirmed that the two
ligands are coordinated from the two amine groups and in cis-conformation with the two
oxygen atoms. The experimental and theoretical calculations show that the two complexes 21
are mononuclear with proposed distorted octahedral structures. The complexes are very
stable, the electronic energies are (-773.10 and -907.56 a.u.), the HOMO orbitals energies
are (-0.386 and -0.504 a.u.), and the LUMO orbitals energies are (-0.213 and -0.421 a.u.) 24
for the complexes; respectively. The bond angles around the vanadium(V) atoms are in the
range (69.44-91.36 A°), and the dihedral angles are in the range (111.22-161.94°).
Calculations explained that the complexes are polarized (3.39-5.28) more than free ligands 27
(0.002-3.00). The electronic transition in the complex (2) (0.083) is less than for the complex
(1) (0.173). After that, the findings showed that the two complexes have the feature of
solubility in water rather than other anticancer compounds that lack such a property; even 30
though using different metal complexes like Platine complexes, etc. Thus, this feature will
help researchers use such complexes in future studies
NEW OXOMOLYBDENUM(IV) COMPLEXES WITH ADDUCTED MONODENTATE LIGANDS, SPECTROSCOPIC CHARACTERIZATION, DFT CALCULATIONS, BIOLOGICAL AND ANTIOXIDANT ACTIVITY
(Bull. Chem. Soc. Ethiop, 2024-06-24) Noor F. Abdalah; Othman I. Alajrawy; Sattar R. Majeed
Oxomolybdenum(IV) complexes with chemical formula [MoO(ATP)(DIAB)(AMP)] (C1),
[MoO(ATP)(DIAB)(Atri)] (C2), [MoO(ATP)(HNQ)(AMP)] (C3) and [MoO(ATP)(HNQ)(Atri)] (C4) have been
synthesized and studied using different spectral methods, including atomic absorption, FTIR, UV-Vis., mass
spectroscopy, magnetic sensitivity, electrical conductivity, and C.H.N.S. analysis. The ligands were 2-
aminothiophenol (ATP), 3,4-diaminobenzoic acid (DIAB), 2-hydroxy-1,4-naphthoquinone (HNQ), 6-amino-2-
methylpyridin (AMP), and 3-amino-1,2,4-triazole (Atri). The FTIR spectra confirm (DIAB, AMP, and Atri) were
coordinated by amine nitrogen, whereas the (HNQ) ligand was by oxygen, and the (ATP) by nitrogen and sulfur
atoms. The υ(S-H) band vanished in comparison to the (ATP) ligand, this demonstrates how Mo(IV) and the sulfur
atom. The (HNQ) ligand's oxygen atoms work in tandem with the Mo(IV). Mo(IV) complexes with d2 are
paramagnetic. All complexes have been suggested to have an octahedral structure based on computed and
experimental evidences. Two Gram-positive and two Gram-negative bacteria were used to test the (ATP) ligand and
the produced complexes' activity. The complexes showed an expanded zone of inhibition, indicating that they were
more lipophilic than the free (ATP) ligand. Finally, the antioxidant activity of the complexes was tested, and the
result showed the following order: Gallic acid ˃ C3 ˃ C2 ˃ C4 ˃ C1 in 60 min.
CLIMATE CHANGE IMPACTS ON TRI-TROPHIC PREDATOR{PREY MODEL OF THE INTERACTIONS BETWEEN WOLVES, UNGULATES, AND PLANTS
(John Wiley & Sons, 2025) ASHRAF ADNAN THIRTHAR; PRABIR PANJA; ZAHRAA ALBATOOL MAHDI; BAPIN MONDAL; ASMA AL-JASER; THABET ABDELJAWAD; MANAR A. ALQUDAH
Abstract
The model considers the interactions between wolves, ungulates, and plants in a three-level
trophic system. Climate change is assumed to have an impact on plant growth, in
uencing the
logistical aspects of plant development. In the absence of ungulate species and climate change,
it is suggested that plants could grow logistically. Ungulates are assumed to consume plants and
this consumption is in
uenced by climate change. Wolves are presumed to consume ungulates,
and the rate of this consumption is believed to be in
uenced by global climate change. The
study discusses the positivity, boundedness, and dissipativeness of the model, likely referring to
the system's behavior and stability. The stability of equilibrium points in the model is studied,
both locally and globally. It is discovered that the populations of ungulates and wolves may go
extinct due to the increase in global climate change. The presence of global warming or climate
change and increased plant consumption by ungulates could lead to instability of the ecological
system. Results from numerical simulations are presented, providing a practical illustration of
the model's behavior under di erent conditions.
