Towards high sensitivity and high-resolution PET scanners: imaging-guided proton therapy and total body imaging
Authors: Lang Karol
Published: December 2022

Quantitative imaging (i.e., providing not just an image but also the related data) guidance in proton radiation therapy to achieve and monitor the precision of planned radiation energy deposition field in-vivo (a.k.a. proton range verification) is one of the most under-invested aspects of radiation cancer treatment despite that it may dramatically enhance the treatment accuracy and lower the exposure related toxicity improving the entire outcome of cancer therapy. In this article, we briefly describe the effort of the TPPT Consortium (a collaborative effort of groups from the University of Texas and Portugal) on building a time-of-flight positron-emission-tomography (PET) scanner to be used in pre-clinical studies for proton therapy at MD Anderson Proton Center in Houston. We also discuss some related ideas towards improving and expanding the use of PET detectors, including the total body imaging.
A double photon coincidence detection method for medical gamma-ray imaging
Authors: Uenomachi Mizuki , Shimazoe Kenji , Takahashi Hiroyuki
Published: December 2022

Cascade nuclides emit two or more gamma rays successively through an intermediate state. The coincidence detection of cascade gamma rays provides several advantages in gamma-ray imaging. In this review article, three applications of the double photon coincidence method are reviewed. Double-photon emission imaging with mechanical collimators and Compton double-photon emission imaging can identify radioactive source positions with their angular-resolving detectors, and reduce the crosstalk between nuclides. In addition, a novel method of coincidence Compton imaging is proposed by taking coincidence detection between a Compton event and a photopeak events. Although this type of coincidence Compton imaging cannot specify the location, it can be useful in multi-nuclide Compton imaging.
Multi-molecule imaging and inter-molecular imaging in nuclear medicine
Authors: Shimazoe Kenji , Uenomachi Mizuki
Published: December 2022

Multi-molecule imaging and inter-molecular imaging are not fully implemented yet, however, can become an alternative in nuclear medicine. In this review article, we present arguments demonstrating that the advent of the Compton positron emission tomography (Compton-PET) system and the invention of the quantum chemical sensing method with double photon emission imaging (DPEI) provide realistic perspectives for visualizing inter-molecular and multi-molecule in nuclear medicine with MeV photon. In particular, the pH change of InCl3 solutions can be detected and visualized in a three-dimensional image by combining the hyperfine electric quadrupole interaction sensing and DPEI. Moreover, chemical states, such as chelating, can be detected through angular correlation sensing. We argue that multi-molecule and chemical sensing could be a realistic stream of research in future nuclear medicine.

In this article, we present the geometrical design and preliminary results of a high sensitivity organ-specific Positron Emission Tomography (PET) system dedicated to the study of the human brain. The system, called 4D-PET, will allow accurate imaging of brain studies due to its expected high sensitivity, high 3D spatial resolution and, by including precise photon time of flight (TOF) information, a boosted signal-to-noise ratio (SNR).

The 4D-PET system incorporates an innovative detector design based on crystal slabs (semi-monolithic) that enables accurate 3D photon impact positioning (including photon Depth of Interaction (DOI) measurement), while providing a precise determination of the photon arrival time to the detector. The detector includes a novel readout system that reduces the number of detector signals in a ratio of 4:1 thus, alleviating complexity and cost. The analog output signals are fed to the TOFPET2 ASIC (PETsys) for scalability purposes.

The present manuscript reports the evaluation of the 4D-PET detector, achieving best values 3D resolution values of <1.6 mm (pixelated axis), 2.7±0.5 mm (monolithic axis) and 3.4±1.1 (DOI axis) mm; 359 ± 7 ps coincidence time resolution (CTR); 10.2±1.5 % energy resolution; and sensitivity of 16.2% at the center of the scanner (simulated). Moreover, a comprehensive description of the 4D-PET architecture (that includes 320 detectors), some pictures of its mechanical assembly, and simulations on the expected image quality are provided.

Published: December 2022

Background Lugol’s solution is well known for its unique contrasting properties to biological samples in in microcomputed tomography imaging. On the other hand, iron oxide nanoparticles (IONPs), which have much lower attenuation capabilities to X-ray radiation show decent cell penetration and accumulation properties, are increasingly being used as quantitative contrast agents in biology and medicine. In our research, they were used to stain 3D cell structures called spheroids. Aim In this study, the micro computed tomography (µCT) technique was used to visualize and compare the uptake and accumulation of two contrast agents, Lugol’s solution and iron (II, III ) oxid e nanoparticles (IONPs) in the in vitro human spheroid tumour model. Methods The metastatic human melanoma cell line WM266-4 was cultured, first under standard 2D conditions, and after reaching 90% confluence cells was seeded in a low adhesive plate, which allows spheroid formation. On the 7th day of growth, the spheroids were transferred to the tubes and stained with IONPs or Lugol’s solution and subjected to µCT imaging. Results Our research allows visualization of the regions of absorption at the level of single cells, with relatively short incubation times - 24h - for Lugol’s solution. IONPs proved to be useful only in high concentrations (1 mg/ml) and long incubation times (96h). Conclusions When comparing the reconstructed visualizations of the distribution of these stating agents, it is worth noting that Lugol’s solution spreads evenly throughout the spheroids, whereas IONPs (regardless of their size 5 and 30 nm) accumulate only in the outer layer of the spheroid structure.
Feasibility study of positronium application for blood clots structural characteristics
Authors: Moyo Simbarashe , Moskal Paweł , Stępień Ewa Ł.
Published: December 2022

Positron-electron annihilation in living organisms occurs in about 30% via the formation of a metastable ortho-positronium atom that annihilates into two 511 keV photons in tissues because of the pick-off and conversion processes. Positronium (Ps) annihilation lifetime and intensities can be used to determine the size and quantity of defects in a material’s microstructure, such as voids or pores in the range of nanometers. This is particularly true for blood clots. Here we present pilot investigations of positronium properties in fibrin clots. The studies are complemented by the use of SEM Edax and micro-computed tomography (µCT) to evaluate the extracted thrombotic material’s properties. µCT is a versatile characterization method offering in situ and in operando possibilities and is a qualitative diagnostic tool. With µCT the presence of pores, cracks, and structural errors can be verified, and hence the 3D inner structure of samples can be investigated.

Definition of Centroid Method as Defuzzification
Authors: Mitsuishi Takashi
Published: December 2022

In this study, using the Mizar system [1], [2], we reuse formalization e orts in fuzzy sets described in [5] and [6]. This time the centroid method which is one of the fuzzy inference processes is formulated [10]. It is the most popular of all defuzzied methods ([11], [13], [7]) – here, defuzzified crisp value is obtained from domain of membership function as weighted average [8]. Since the integral is used in centroid method, the integrability and bounded properties of membership functions are also mentioned to fill the formalization gaps present in the Mizar Mathematical Library, as in the case of another fuzzy operators [4]. In this paper, the properties of piecewise linear functions consisting of two straight lines are mainly described.

Single channel convolutive blind source separation for LFM radar signals
Authors: Xu Pengfei , Jia Yinjie , Guo Xinnian
Published: December 2022

We propose a single channel blind source separation algorithm for convolutively mixed linear frequency modulation (LFM) signals based on smoothed Wigner-Ville distribution (SWVD) time-frequency analysis, Canny edge detection, and Hough transform detection. First, the SWVD time-frequency analysis diagram is obtained as an image based on the LFM time-frequency characteristics. Second, Canny edge detection is performed on the image. Then, Hough transform is used to detect the characteristic parameters of the linear signal. Finally, the source signal is recovered. The simulation results show that the algorithm is effective for single channel detection and extraction of convolutively mixed LFM signals.
Lightweight ultra-wideband antenna array equipped with thin frequency selective surface for high-gain applications
Authors: Prasad Pratyancha , Singh Shiva Nand , Kumar Akhilesh
Published: December 2022

This article begins with an explanation of a frequency selective surface, also known as an FSS, which is used to increase gain across a wide frequency range. The proposed unit design is a modified combination of circular and square elements with two cross dipoles and a T-type structure at the inner side. In the second step of the process, a single wideband antenna that covers the same range as FSS is designed and then analyzed in terms of its gain and radiation patterns. After that, an antenna array was built using the same solo structure in order to take advantage of the benefits that come with using an array system. The array is made up of elements that are CPW fed. A ground-backed T-shaped power divider network with additional shorting pins is used to supply power to the entire array. In the fourth step, an array of the FSS unit cell has been positioned beneath the UWB solo antenna and its array in order to investigate the possibility of improved gain and radiation pattern. The FSS equivalent lumped circuit model is presented here for validation purposes. It has been determined that the results of the experiment and the simulation are consistent with one another. In contrast to the structures that have been reported in the past, the newly developed model possesses a greater bandwidth, a higher gain, and a lower profile.
Run length limited CCSDS convolutional codes for optical communications
Authors: Farkaš Peter , Divinec Ladislav , Rakús Martin
Published: December 2022

This paper presents the construction of RLL-ECCs (run length limited error control codes) from three selected ECCs specified by Consultative Committee for Space Data Systems (CCSDS) for optical communications. The RLL-ECCs obtained present a practical alternative to CCSDS codes with pseudo-randomizers. Their advantage is that the maximal run lengths of equal symbols in their codeword sequences are guaranteed, which is not the case if the common approach with pseudo-randomizers is used. The other advantages are that no additional redundancy is introduced into encoded codewords and that the encoding and decoding procedures of the original error control CCSDS codes do not have to be modified in the following cases: Firstly, if hard decoding is used and the transmission channel can be modeled as a BSC (binary symmetric channel) and secondly, if soft decoding and coherent BPSK (binary phase shift keying) modulation is used and the appropriate transmission channel model is an AWGN (additive white Gaussian noise) channel.

Cardiovascular disease (CVD) represents the leading cause of mortality worldwide. In order to diagnose CVDs, there are a range of detection methods, among them, the impedance cardiography technique (ICG). It is a non-invasive and low-cost method. In this paper, we highlight recent advances and developments of the CDVs diagnosis mainly by the ICG method. We considered papers published during the last five years (from 2017 until 2022). Based on this study, we expressed the need for an ICG database for the different CDVs.
Handling Waste on Ships: A Model Based on Safety and Awareness
Authors: Kuncowati  , Sholihah Qomariyatus , Ciptadi Gatot , Koderi
Published: December 2022

Internationally, waste handling on ships is regulated in Annex V of the Marine Pollution (MARPOL) regulation 1973/1978. Crews’ knowledge and competence in waste management and safety are specified in the Standards of Training, Certification, and Watchkeeping for Seafarers, Manila 2010. However, research shows that waste is still discharged into the sea, which disturbs the aesthetics and negatively impacts the marine environment, ecosystem, and people’s safety and security. This study investigates waste handling by container ship crews. Data were collected through a survey with 180 container ship crews at Tanjung Perak Port, Surabaya, Indonesia; and analysed using Structural Equation Modelling-Partial Least Square (SEM-PLS) software. The finding suggested a positive and significant impact of the crews’ roles in preventing marine pollution, at 31.5%. This finding confirms the need for a waste handling model on ships that considers safety and awareness. This study suggests improvements in ship management and crews’ awareness of waste handling aimed at environmental protection.

Authors: Hałabuza Justyna , Rzepa Grzegorz , Manecki Maciej , Białek Justyna
Published: December 2022

The immobilization effect of soil amendments on leaching and bioavailability of Pb, Zn and Cd in highly contaminated soils under industrial impact was studied by collecting the soils in the surroundings of Zn-Pb Smelter “Miasteczko Śląskie” in southern Poland as an example. Various amounts of four additives (phosphate fertilizer, limestone powder, bentonite rock and bog iron ore) were tested in laboratory experiments to compare the effectiveness of three dominant mechanisms of immobilization: precipitation of phosphates, pH increase, and sorption. The contents of metals before immobilization were determined by extraction in CaCl2, EDTA and aqua regia. Cadmium and zinc are mainly represented by soluble, bio-available forms extractable in CaCl2, while lead by potentially bioavailable speciations extractable by EDTA. Most effective in the immobilization of these metals were the amendments increasing soil pH: limestone powder and phosphate fertilizer. Bog iron ore and bentonite were less effective because the soil pH was too low for efficient cation adsorption.

The evidence of past disasters can be used to support disaster risk reduction efforts. Many records of past disasters are obtained in the field based on geological studies related to disasters, for example the paleotsunami sediments of the Gua Ek Leuntie. The education process for this evidence cannot be carried out directly in the field. Therefore, an effort is needed so that evidence of past disasters can be presented to the community, for example through making replicas. This study aims to describe the process of making a replica of the Gua Ek Leuntie tsunami sediment and evaluate its design and use as a learning tool about the tsunami. Making a replica of the tsunami sediment of the Gua Ek Lentie was carried out using modeling techniques. The replica was placed in the Tsunami Museum to be assessed for its design and use by visitors, museum staff and artists. Data were collected by using observation and semi-structured interview techniques and then analyzed by qualitative descriptive. The result obtained is a replica that is similar to the original. Analysis of the design and use shows that replica can be a learning tool about tsunami

Published: December 2022

Subject. The article deals with dominant indicators in the integrated assessment of enterprise’s financial condition.
Objectives. The focus is on practical application of the concept of dominant indicators in the financial analysis of the enterprise.
Methods. The main tool of the study was an algorithm for conducting a complex analysis of financial condition of the enterprise and identifying the dominant indicators that determine the final financial result.
Results. We performed a comprehensive analysis of financial condition of three large grain processing enterprises operating in various regions of the Volga Federal District. The paper identifies dominant indicators that most accurately reflect the impact on profits.
Conclusions. As practice shows, the analysis of various coefficients may provide ambiguous information. For instance, there may be situations when low liquidity indicators are revealed, but financial results with the existing asset structure are high enough and the company's activities are highly profitable. That is, the values of some indicators do not always characterize the enterprise’s performance quite accurately and unambiguously. To determine dominant indicators is a necessary tool for understanding the real impact of individual economic parameters on the final financial result.
Control function of finance and its application in public financial management
Authors: LUKIN Andrei G.
Published: December 2022

Subject. The article investigates the essence of control function of finance, its implementation in the system of economic relations, and application in the public administration sector.
Objectives. The aim is to substantiate the thesis that it is necessary to develop theoretical approaches to the implementation of control function of finance to improve public administration in the Russian Federation.
Methods. I employ universal methods of scientific knowledge, like analysis, synthesis, generalization, abstraction, and methods of modeling, induction and deduction.
Results. The study indicates boundaries of the difference between audit and financial control, demonstrates options for using the opportunities provided by the control function of finance within the financial system of the Soviet Union and the financial system of a modern democratic federal State with a market economy. Using the case of the health care reform failure in the Russian Federation, I show a possible negative impact of the control function of finance, if incorrect approach to its implementation is applied.
Conclusions. At present, it is impossible to implement the opportunities provided by the control function of finance in public administration in the Russian Federation, as there are no approaches to formulating the financial result of activities of institutions rendering public services. Nevertheless, it is necessary to apply certain methods to select optimal management decisions, since measuring the performance of public institutions in physical terms is either very cumbersome or impossible. I suggest using the experience of the Soviet Union in the development of financial indicators of enterprise performance.

الارتباط الدلالي بين الجبن والألفاظ الدالة عليه في معجم لسان العرب
Authors: Mustafa Idrees Sulaiman
Published: December 2022

تعد مسألة الحقول الدلالية ميدانا خصبا للدراسة ولا سيما إذا كان موضوع البحث يرتبط بدراسة في المعجم العربي وقد وقع اختيارنا على دراسة الألفاظ الدالة على الجبن في معجم لسان العرب بعدِّه واحدا من المراجع الأصلية في البحث اللغوي ومعجما كبيرا ورئيسا في تناول ألفاظ اللغة.
    وقد كان البحث مبنيا على أساس إيجاد الارتباط الدلالي بين معنى الجُبن والألفاظ التي ذكرها ابن منظور (ت711ه) في معجمه وصرح بدلالتها على المعنى المذكور من خلال الحقول الدلالية التي قسمنا الألفاظ في ضوئها؛ إذ إن كل مجموعة من الألفاظ تدل على الجبن من حيثية غير ما تدل عليه مجموعة أخرى، ولم نأل جهدا أو ندخر وسعا في تقسيم الدلالات الفرعية على معنى الجبن.

قضية التسليح واثرها على النفوذ البريطاني – الامريكي في العراق 1945-1957
Authors: Jasim Hammadi Ghaffar Jabbar
Published: December 2022

رغم تغلغل النفوذ الأمريكي في العراق وتوسعه خصوصاً في مجال المساعدات العسكرية للجيش العراقي إلا أنها لم تكن بالمستوى المطلوب ولم تصل إلى ما وصلت اليه العلاقات العراقية البريطانية من مستوى ، ويمكن أن نعلل سبب ذلك إلى أن البريطانيين عندما دخلوا إلى العراق اتبعوا سياسة تتمثل في السيطرة على الأمور بصورة مباشرة ، خصوصاً وأنهم قاموا بإبدال سيطرتهم العسكرية بسيطرة أخرى تتمثل بالانتداب وتكبيل العراق بالمعاهدات التي أرغمته وأجبرته على الانسياق وراء السياسة البريطانية ، حيث سيطر مستشارو بريطانيا تقريباً على كافة نواحي الإدارة مما خلق صراعاً بين هاتين الدولتين على طوال الفترة التي حاول من خلالها الأمريكان التغلغل في العراق وبالتحديد بعد الحرب العالمية الأولى .
لم يقتصر الدور البريطاني-الأمريكي في ميدان الجيش على التسليح فقط بل أمتد أيضاً إلى البعثات العسكرية التي كان العراق يقوم بأرسالها إلى الخارج أو من خلال الدعوات التي كان يتلقاها الضباط العراقيون من قبل بريطانيا والولايات المتحدة ، ورغم الدور المحدود الذي تشكله هذه البعثات من ناحية قلة عدد أفرادها إلا أن جدواها ومردودها المعنوي كبير جداً ، إذ أن هؤلاء الضباط الموفدين إلى بريطانيا وأمريكا يقومون بنقل الخطط والأفكار التي يدرسونها ويتعلمونها في تلك البلاد ، وبما انه كان هناك تنافس بريطاني أمريكي فمن الطبيعي أن تقوم هذه الدول باتخاذ هذه البعثات كوسائل لنقل أفكارها ومبادئها لا سيما وأن هذه الدول تنظر إلى الأمور بمنظار بعيد .
الانعكاسات البصرية للتقنيات المسرحية وأثرها في عروض مسرح الطفل
Authors: Al- Baglan Mayada Majid Amin , Hashem Al-Shammari Muhammad Kazem
Published: December 2022

مسرح الطفل هو منظومة قيمية أخلاقية تربوية يسعى القائمين عليه إلى إثارة اهتمام الطفل وتشويقه من خلال التركيز على العوامل المؤثرة التي تعمل على جذبه والتأثير عليه مع مراعاة الجانب السلوكي والإدراكي لديه , فالطفل كمتلقي وناقد صغير يختلف ميوله عن المتلقي العام او المسرحي , من حيث السلوك وإكتمال الشخصية , وتعتبر الانعكاسات المرئية كتقنيات مسرحية لاتتمثل باللون فحسب بل هي فكر تتعامل مع منطق الأشياء في استحضارها على خشبة المسرح مع تعزيز الموقف الدرامي بفاعلية كبيرة من خلال الجذب والتواصل, ولكي يبقى الطفل متابعا للعرض المسرحي علينا التركيز على الانعكاسات البصرية التي نحاول بها جذب اهتمامه وإثارة انتباهه, فهــو كمتلقي لايسعى لأن يسمع فقط بل ليرى ويتفهم ويبحث في كثير من الأحيان, لذلك ركزنا على البصريات المسرحية كعناصر سينوغرافية ذات حركة مستمرة متآلفه تجعل منه متابعاً يقظاً, ويحاول هذا البحث ان يبرز ادوات التعبير ولكن في صياغات جديدة تؤكد على الأعمال التصميمية والتي بدورها سوف تؤسس للعناصر البصرية التي تعتبر أساس الجذب البصري لتحقيق التفاعل الاجتماعي والترفيهي لدى الطفل.

Dash  is in need to be read and understood by the readers. Though dash creates a certain problem in the poem, it achieves various benefits of reflecting the sighs, emotion and loss  without writing words.

من نعم الله تعالى علينا خلقه للكرة الارضية لنعيش عليها ونحافظ عليها من المخاطر وان يكون لنا دورفي حمايتها من التلوث الذي يهدد صحة الانسان لذلك  سلطت هذه الدراسة الضوء على  الدراسات الفقهية الدقيقة الخاصة بهذا الموضوع. لقد ركزت  الشريعة الاسلامية على حماية الارض من التلوث والمحافظة على مواردها من الاستنزاف وسوء الاستخدام بدءا من تربية الوازع الايماني والعقائدي في قلب كل مسلم للمحافظة على نعم الله تعالى وحماية الارض  وتنمية اخلاقه للـتأدب مع الموارد الطبيعية.  لقد وضعت الشريعة الأسلامية الاسس والقواعد الشرعية القائمة على حفظ البيئة وحسن استغلالها، ثم جاءت الفروع الفقهية لتجد في كل فرع منها مسألة فيها رعاية واهتماماً بقضايا التلوث واحاطت ذلك كله بسياج المقاصد الكبرى في جلب كل مصلحة فيها اصلاح وحفظ لحياة الانسان من التلوث، ودفع لكل مفسدة فيها افساد واضرار بحياة الانسان. لذلك وجب توعية البشرية لمدى الارتباط الوثيق بين أحكام الشريعة الاسلامية  وحياة الانسان مع وضع استراتيجية عامة لنشر الثقافة بين جميع طبقات المجتمع وعلى المستويات كافة للحفاظ على الكرة الارضية.  كما يجب التوجه للعمران في الاراضي البوروذلك لحماية المناطق الزراعية من الامتداد السكاني لها وتجريفها واقامة المشاريع السكانية والصناعية والاستثمارية بما يتلائم مع متطلبات المجتمع وحاجياته.
تنظيم أوضاع الجيش الجديد( عساكر المنصورة المحمدية)
Authors: Taha Maki Yousef Abd alkarim , Talib Jamal Subhi
Published: December 2022

أدت المؤسسة العسكرية دوراً استثنائياً في قيام الدولة العثمانية واستمرارها حتى سقوطها، فقد كانت الدولة منذ نشأتها، عسكرية الطابع، فليس هناك ثمة خط فاصل بين ما هو مدني وما هو عسكري فيها، فقد برع العثمانيون في التنظيم العسكري واقتبسوا في البداية الاساليب العسكرية البيزنطية وطوروها، فأصبحت الاساس الذي قامت عليه مؤسستهم العسكرية فيما بعد، هكذا كان للمؤسسة العسكرية اهمية كبيرة في بناء الدولة العثمانية منذ نشأتها فهي ادارة للحكم والحرب معاً.   
    إلا ان كثرة الاخفاقات السياسية والعسكرية اقنعت السلطان محمود الثاني في بداية عشرينات القرن التاسع عشر بضرورة القيام بإصلاحات جذرية في المؤسسة العسكرية فقد اثبت الجيش الانكشاري انه كان سبباً في الفشل الذي اصاب تلك المؤسسة، إذ تقاعس الكثير من الانكشاريين في الذهاب إلى ثكناتهم العسكرية المخصصة لهم لأداء الواجب العسكري المطلوب منهم ، وكانوا لا يذهبون إلا لتسلم الرواتب. ذلك الامر دفع السلطان محمود الثاني الى الغاء الجيش الانكشاري وتشكيل جيش جديد سمي بعساكر المنصورة المحمدية والذي ابدى اهتمامه الكبير في تنظيم ذلك الجيش ليكون منافساً قوياً للجيوش الاوربية
التعايش السلمي مع أهل الذمة في ظل الدولة العربية الإسلامية
Authors: Jassim Muayad Hameed
Published: December 2022

أهل الذمة يقصد به كلا من النصارى واليهود أهل الكتاب وأصحاب الديانات الأخرى الذين يعيشون تحت الحكم الإسلامي أو في البلاد التي تدين الإسلام .  استعمل المسلمون كلمة (الذمة) هو عهد رسول الله (صلى الله عليه وسلم) إلى نصارى أهل نجران، فالذمة هي ذمة الله ورسوله وليست ذمة أحد من الناس. بقاؤها لضمان الحقوق لا إهدارها، ولاحترام الدين المخالف للإسلام لا لإهانته  ولإقرار أهل الأديان على أديانهم ونظمها لا لحملهم على الزهد فيها أو الرجوع عنها. ومع ذلك فهي عقد لا وضع. جاءَ الإسلام الحنيف في زمن رسول الله مرتبطًا بكميةٍ من الرسالات السامية، والتي تُعبِّر عن مضمون الإسلام، وتدافع عنه في كل مواقفِ الشُبهات، وما يحصل من تشويه لرسالة الإسلام السمحة التي يدعيها من لا يعرف الإسلام ولا ينصفه؛ فقد أمر الإسلام بالتسامح والصفح وحُسن التعايش مع كل الناس بغض النظر عن أطيافهم وأديانهم ومعتقداتهم، وذلك عن طريق احترام حريته الدينية والسياسية والفكرية، ومن الجدير بالذكر أنّ رسالة الإسلام لم تنتشر بحد السيف كما يتمُّ تشويهها، بل إنَّ السماحة والعدل والعلم هم من ساهموا في نشر هذه الرسالة السامية، وذلك مما ما تدل عليه القصص المذكورة من تعامل المسلمين مع أهل الذمة وتعايشهم معهم ومشاركتهم حياتهم .
مشروع جنوب شرقي الأناضول وتأثيره في حدوث الزلازل والهزات الأرضية
Authors: Mahmood ALAbbassi Rayyan Dhannoon
Published: December 2022

تزايد حدوث الزلازل والهزات الارضية في عددٍ من المدن التركية، رجّح الخبراء أسبابها الى وجود علاقةٍ مباشرة أو غير مباشرة، بالمشاريع المائية المقامة في منطقة جنوب شرقي الاناضول، المعروف عنها بتعّقد مظاهرها التضاريسية. وقد دفع ذلك الحكومة التركية الى القيام بوضع تصاميم فنية لبعض منشآت المشروع المذكور، لكي تقاوم شدة تلك الظواهر الطبيعية، وتكون قادرة على امتصاص قوة الزلزال اذا ما وقع. وتراوحت درجة قوة الزلازل بين (6-8) درجة على مقياس ريختر، وهو دليل واضح على معرفة السلطات التركية بأن تلك المنطقة، تنشط فيها تلك الظواهر الطبيعية التي يكثر وقوعها بين حينٍ واخر، بالرغم من اصرارها على تنفيذ ذلك من اجل غاياتٍ وأهدافٍ سياسية واقتصادية تسعى لها .
