Effects of Cyclic Freezing–Thawing on Dynamic Properties of Loess Reinforced with Polypropylene Fiber and Fly Ash
Authors: Chen Shufeng , Luo Tao , Li Gang , Zhang Yao
Published: January 2022

Periodic freezing–thawing is recognized as a real threat to the mechanical properties of reinforced loess, which has been used in the recent construction of high-speed railways in northwest China; however, the performance of these materials under periodic freezing–thawing and dynamic loading has rarely been investigated. In this work, dynamic triaxial tests were conducted on fly ash- and polypropylene fiber-reinforced loess with different blend ratios and freeze–thaw cycles. The dynamic shear modulus and damping ratio were investigated. The results revealed that cyclic freezing–thawing had a remarkable effect on the dynamic shear modulus and damping ratio, which demonstrated considerable reductions and increases, respectively, after cyclic freezing–thawing. Additionally, the dynamic shear modulus increased notably with the fly ash content and confining pressure and decreased with the water content. Meanwhile, the damping ratio increased with the fiber content and water content and decreased with the fly ash content and confining pressure. Comparatively, the effects of polypropylene fiber on dynamic behavior were found to be not significant. Furthermore, novel models were established to predict the dynamic shear modulus and damping ratio for reinforced loess. The results provide more information towards infrastructure design in seasonal frozen regions.
Estimating the Evaporative Cooling Effect of Irrigation within and above Soybean Canopy
Authors: Ghafarian Fatemeh , Wieland Ralf , Nendel Claas
Published: January 2022

Vegetation with an adequate supply of water might contribute to cooling the land surface around it through the latent heat flux of transpiration. This study investigates the potential estimation of evaporative cooling at plot scale, using soybean as example. Some of the plants’ physiological parameters were monitored and sampled at weekly intervals. A physics-based model was then applied to estimate the irrigation-induced cooling effect within and above the canopy during the middle and late season of the soybean growth period. We then examined the results of the temperature changes at a temporal resolution of ten minutes between every two irrigation rounds. During the middle and late season of growth, the cooling effects caused by evapotranspiration within and above the canopy were, on average, 4.4 K and 2.9 K, respectively. We used quality indicators such as R-squared (R2) and mean absolute error (MAE) to evaluate the performance of the model simulation. The performance of the model in this study was better above the canopy (R2 = 0.98, MAE = 0.3 K) than below (R2 = 0.87, MAE = 0.9 K) due to the predefined thermodynamic condition used to estimate evaporative cooling. Moreover, the study revealed that canopy cooling contributes to mitigating heat stress conditions during the middle and late seasons of crop growth.
A review of the science and clinical use of alcohol-based hand rubs
Authors: Ah-Gi Lo Elaine , Siu-Chun Law Lawrence , Tan Kevin , Ashokka Balakrishnan
Published: January 2022

Alcohol has a longstanding history as an antiseptic, and the coronavirus disease 2019 (COVID-19) pandemic has sparked a renewed interest in its use as a hand sanitizer. Alcohol works by denaturing protein and rendering cell membranes permeable. It offers excellent germicidal effects against Gram-positive and Gram-negative bacteria, Mycobacterium tuberculosis, fungi, and lipid-containing viruses. However, it is less reliable against non-lipid containing viruses and is ineffective against bacterial and fungal spores. Alcohol-based hand rub (ABHR) usually contains 60–90% isopropanol or ethanol. Additives such as chlorhexidine to complement the action of alcohol and emollients to ameliorate the drying effect of alcohol are often included to improve the formulation of ABHR. In the clinical setting, ABHR provides biocidal activity against multidrug resistant bacteria such as methicillin-resistant Staphylococcus aureus as well as viruses like human coronavirus, severe acute respiratory syndrome coronavirus, and Middle East respiratory syndrome. Moreover, its use is associated with an improved compliance with hand hygiene, which has been shown to translate into better patient outcomes. However, there are cases of intoxications secondary to ingestion of ABHR or adulterated alcohol when resources are diverted away from the normal beverage production to meet the increased need for hand sanitizer during the COVID-19 pandemic. The risk of unintentional topical absorption and fire hazard among healthcare workers is low but should not be ignored. We proposed recommendations to mitigate the risk of ABHR ingestion and poisoning as well as that of fire hazard.

Analyse des liens génétiques entre deux manuscrits musicaux attribués à Luxeuil
Authors: Nishimagi Shin
Published: January 2022

The present article reconsidered Jacques Chailley's hypothesis that the origin of the first libellus of BnF lat. 7211 (f. 1-72) was Luxeuil. His evidence, based on a codico-logical comparison with BnF lat. 7212, which contains a papal bull on the favor of Saint-Pierre monastery at Luxeuil, is convincing, since these two manuscripts correspond in many details. However, textual differences between these two manuscripts suggest that lat. 7211 is not directly copied from lat. 7212. Instead, these two manuscripts perhaps share a common source written at the scriptorium of Luxeuil or in the north-west of France. Lat. 7211 was bound later with other libelli, in the 12th century, in a region which used Aquitanian neumatic notation.
La co-tradition : quelques réflexions autour d’un outil heuristique pour les études manuscrites
Authors: Brix Antoine
Published: January 2022

Methodological in essence, this paper aims at calling French scholars’ attention to what is referred to as Mitüberlieferung in German academic literature. This concept is largely missing from the realm of French manuscript studies, wherein no faithful rendition of the word exists. The neologism co-tradition is proposed for use in the first part of this paper, while the rest argues, relying on a selection of examples, for the inclusion of co-tradition in the French manuscript scholar’s toolbox, both as a means to describe and characterise historical material and as a way to raise codicological questions and address philological issues.
At the Crossroads of Textual Transmission : Catalano-Septimanian Martyrologies and New Research Questions
Authors: Novokhatko Ekaterina
Published: January 2022

Les martyrologes, sources cruciales dans la liturgie médiévale quotidienne, ont été récemment analysés du point de vue de leur rôle dans le développement d’une communauté religieuse locale, dans la formation de son histoire et identité. Cet article offre une nouvelle perspective sur les martyrologes catalans et septimans (X-XII s.) en les analysant comme media qui tracent les routes de communication et organisent les réseaux spirituels et institutionnels. L’article démontre la fonction des martyrologes dans la transmission des cultes de saints universels à travers la typologie et la fréquence des auctaria ajoutés dans le texte principal ainsi que leur provenance des traditions textuelles diverses. L’analyse structurelle et contextuelle des martyrologes, bien que contradictoire, met en lumière les liens entre les institutions religieuses et aide à révéler les stratégies religieuses derrière la diffusion de nouveaux cultes et fêtes.

Published: January 2022

Introduction: This study was conducted to assess the microleakage in Er:YAG laser-ablated and bur-prepared root and coronal dentin cavities using self-etch and total-etch adhesive systems. Methods: Sixty extracted caries-free human third molars were sectioned for dentin exposure. Then, two standard class V cavities were prepared in the root and coronal dentin of each tooth and allocated to one of the following conditioning groups randomly (n=12/Group): G1: Diamond bur for cavity preparation and single bond (BESB) etch-and-rinse adhesive for bonding, G2: Er:YAG laser (160 mJ, 20 Hz, 29.88 J/cm2 ) and SB (LESB), G3: Er:YAG laser and SB without acid etching (LSB), G4: Diamond bur and Clearfil SE Bond (BCSE) self-etch system, and G5: Er:YAG laser and Clearfil SE Bond (LCSE). The cavities were filled with Z100 composite resin. Dye penetration was assessed after thermocycling. Data analysis was done by Kruskal–Wallis and Mann–Whitney U tests. Statistical significance was set at P<0.05. Results: The results showed there were no statistically significant differences in microleakage between the two preparation methods (bur and laser) or the bonding agents applied (P>0.05). Regardless of the cavity preparation method, dye penetration was significantly higher in coronal dentin than in root dentin (P<0.05). Conclusion: The Er:YAG laser had the same efficacy as the conventional method for cavity preparation, and microleakage did not depend on the bonding agent. Microleakage was significantly higher in coronal restorations than in root restorations.

Published: January 2022

Introduction: Acute lymphoid leukemia (ALL) is a malignant disease, the prognosis of which depends on the age of the patient and the treatment. The aim of this article was to report the treatment of this rare and interesting case of alveolar osteitis with antimicrobial photodynamic therapy (aPDT) in a patient with ALL that was resolved efficiently and quickly. Case Presentation: A 33-year-old male diagnosed with ALL attended the public service, complaining of pain in the region of tooth 48, without function. Extraction was performed, and the patient returned for postoperative follow-up, complaining of severe pain in the area of the alveolus. Clinical examination revealed osteitis. The alveolus was treated using aPDT with 0.005% methylene blue photosensitizer, followed by the application of a low-level red laser at a wavelength of 660 nm (321 J/cm2 – site). After 15 days, soft tissue closure was observed and complete filling of the alveolus was observed radiographically with a 7-month follow-up. Conclusion: The authors suggest that aPDT can be an effective treatment of alveolar osteitis in a patient with ALL.
Biographical and Cultural Evolution of Paanar
Authors: P Sridevi
Published: January 2022

Tamil literary tradition registers 'tinai' divisions which is "a language with in a language" comments A.K. Ramanujan as it provides infinite possibilities to create in a finite frame. Along with people in respective landscapes, there are a nomadic group of paanar who visited all five landscapes spreading the oral tradition. References about the paanar, their oral tradition and nomadic lifestyle are found in cankam literature. There are different kinds of paanar referred performers, singers, declaimers, kuttar, viraliyar, poribar and panar along with their female counterparts and characteristic instruments. Records correspond that they were nomadic and visited kings to sing their praise and receive gifts. Their female counterparts were called 'viraliyar'. The Bard community depended on Kings and patrons for their livelihood. They are also called as 'isai panar' or musical paanar. They are further classified into three 'isai panar', 'yazh panar' and 'mandai panar'. This classification is also considered as separate caste by some and separate sect by others. These three sects of paanar are the ancestors of paanar. This research paper intends to study whether this nomadic lifestyle, singing the praise of kings, depending on kings' gifts for livelihood gave the paanar contentment in life from anthropological perspective.
Exclusion of a contractor from participation in a public procurement procedure as a result of contract termination for reasons attributable to them
Authors: Bojko Justyna , Puto Malgorzata
Published: January 2022

Abstract: The article describes obligatory and optional grounds for excluding a contractor on the basis of Polish Public Procurement Law, taking into account the jurisprudence and views of the doctrine. The attention is paid to the optional ground based on art. 24 sec. 5 point 4 of the Polish Act of January 29, 2004, Public Procurement Law, according to which the contracting authority may exclude from the procurement procedure contractors who, for reasons attributable to them, failed to perform or to a significant extent improperly performed a prior public procurement contract or concession contract concluded with the contracting authority, which led to termination or awarding compensation. In order to be able to use the institution, the contracting party must include an appropriate clause in the contract, providing for the possibility of terminating the contract or awarding damages due to contractor’s non- performance or improper performance of the contract, which is a common practice on the Polish public procurement market. However, in the event of such a clause, the contracting authority is obliged to apply it if the condition is met. The article also describes the self- cleaning institution, derived from art. 57 sec. 6 of Directive 2014/24/EU. The self-cleaning procedure can protect the contractor from being excluded from future tenders. However, In order to take advantage of self-cleaning, the contractor has to admit that non-performance or improper performance of the contract is their fault. Keywords: Exclusion; Contract

Published: January 2022

Urbanization has increased rapidly in the world. It uses an intensive resource consumption for urbanization and the expanding economy. The consequences of unconscious consumption of these resources, which constitute the thermodynamic system of cities, are solid wastes, wastewater and air pollution. As a result of improper management of these wastes in cities, it increases the effect of climate change by producing greenhouse gas emissions directly or indirectly. The most innovative approach in controlling these effects is “low-carbon city” studies. Turkey should give priority to low-carbon city applications that compliance with the European Green Deal and transition to a green economy. In this context, with this study, applications and solutions were examined together to become a low-carbon city in Turkey. Considering policies and commitments, the roadmap is drawn in this way, the study will be a reference for many cities.

Published: January 2022

Coal combustion generates many gases and emissions which are harmful to public health and the environment. So, it is necessary to assess the health risks for the people living in the nearby cement plants that use coal as a fuel. In this article, a health risk assessment HRA was carried out concerning the air emissions from a cement plant in the heavy industry area located at Beni Suef governorate - Egypt. The article handles the assessment of the health risks for pollutants classified as non-carcinogenic i.e. sulfur dioxide - mercury and the health risks for pollutants classified as carcinogenic i.e. arsenic – chromium VI. An Air dispersion modeling program AERMOD is used to measure and evaluate long and short terms health impacts to expect the concentration of pollutants at the ground level within 30 km radius of the studied cement plant. The emissions measurements findings are used as input to the model in addition to some factors such as meteorology and surrounding terrain. Consequently, the program can implement simulations for the emissions concentration level of the mentioned pollutants and their effects on the population at Jazirat Abu Salih village, which is 10 km far from the studied cement plant. The results for mentioned pollutants concentrations levels matched with acceptance and safe levels of ambient air quality standards. In addition, the increment lifetime cancer risk ILCR by inhalation was calculated for arsenic and chromium and all results conformed with the safe and accepted limits.

Published: January 2022

Plastics can reach the coastal environment and could impact the marine environment. Mussels are marine organisms which are prone to be exposed to microplastics pollution. Therefore, in this preliminary study, the commercially important green mussel (Perna viridis) collected at the Koh Phee Canal in Phuket, Phuket Province, southern peninsular Thailand, was investigated. The collected mussels from aquaculture farm fell into three age groups, namely 1 year-1 month, 1 year-7 months, and 1 year-9 months. Results from the investigation showed 200 items of microplastics present in Perna viridis with 76 items (38%) in flushed water and 124 items (62%) in the soft tissue. The average counts of microplastics in soft tissue and flushed water were 4.13 items per individual and 2.53 items per individual, respectively. Blue color (98 items, 49%) and filament shape (185 items, 92.5%) were the most common color and shape of microplastics in the mussel tissues and the flushed water. The dominant polymers as microplastics were identified as polyester and polyethylene terephthalate, which are common polymer types used in protective packaging and containers. The statistical post hoc tests showed no significant differences by age group in the microplastics accumulation in the Perna viridis (p<0.05). Further studies are required to understand the accumulation rates and residence times of microplastics across the food webs for better understanding on their impacts on human health. The results from this study provide a baseline level of microplastics contamination in green mussel aquaculture located at Phuket, and urgent measures are needed to prevent contamination of food for human consumption and related health problems.
Chirality-controlled enantiopure crystal growth of a transition metal monosilicide by a floating zone method
Authors: Kousaka Yusuke , Iwasaki Satoshi , Sayo Taisei , Tanida Hiroshi , Matsumura Takeshi , Araki Shingo , Akimitsu Jun , Togawa Yoshihiko
Published: January 2022

We performed a crystal growth to obtain chirality-controlled enantiopure crystals using a laser-diode-heated floating zone (LDFZ) method with a composition-gradient feed rod. It has been argued that the crystal handedness of TSi (T : transition metal) is fixed depending on T in the case of the ones grown by the conventional methods. We found that right-handed single crystals of CoSi and MnSi were grown from the composition-gradient feed rods that consist of FeSi–CoSi and FeSi–MnSi, respectively. The obtained CoSi and MnSi crystals inherit the chirality from the seed part of FeSi, which grows in a right-handed structure, and thus has the chirality opposite to that for the crystals in the literature. The LDFZ method with the feed rods with various combinations of TSi compounds enables flexible control of the chirality of TSi and will be useful for clarifying the interplay between crystalline chirality and chirality-induced physical responses.
Optical properties of copper naphthalocyanine nanoparticles prepared by laser ablation in liquid
Authors: Omura Keita , Kitamoto Yoshitaka , Hara Masahiko , Wada Hiroyuki
Published: January 2022

Copper naphthalocyanine nanoparticles were successfully prepared by laser ablation in liquid. Micron-size copper naphthalocyanine powders were used as the raw material in water and were irradiated with a laser beam (Nd:YAG, SHG) to obtain nanoparticles. Nanoparticles were examined by scanning electron microscopy, dynamic light scattering, a spectrophotometer, and Raman spectroscopy. Even in the case of irradiation at low laser fluence and for short irradiation times, nanoparticles were obtained owing to the comparatively low threshold of laser ablation. Laser irradiation changed the crystal structure, but the composition of the nanoparticles was not altered by laser irradiation. The dispersion stability of nanoparticle solution was very high, and absorbance of the solution was almost constant without precipitation. The conversion rate from raw material to nanoparticle was 85.5%. The Grüneisen coefficient for the copper naphthalocyanine nanoparticles was also high; therefore, the produced copper naphthalocyanine nanoparticles were suitable as a contrast agent for photoacoustic imaging.

The Infrequently Sung ‘a’ Instead of ‘A’ in ‘Alleluia’ According to the Coptic Tradition
Authors: Henein Michael , Azer Shereen , Khirey Joseph , Pahor Ahmes , Isshak Nabil
Published: January 2022

We attempted to study the hitherto unexplained phenomenon of the sung “a”, for one note, at the end of an “A” melody. We encountered this issue during singing the word “Alleluia” in the Coptic musical culture. We found that the transmission from “A” to “a” serves as an intermediary step before continuing to the “L”. It may also be an adopted habit by some singers, rather than a consistently inherited musical design with a clear pattern. However, further research is encouraged to decipher this phenomenon.

Published: January 2022

Freezing of Gait is the most disabling gait disturbance in Parkinson’s disease. For the past decade, there has been a growing interest in applying machine learning and deep learning models to wearable sensor data to detect Freezing of Gait episodes. In our study, we recruited sixty-seven Parkinson’s disease patients who have been suffering from Freezing of Gait, and conducted two clinical assessments while the patients wore two wireless Inertial Measurement Units on their ankles. We converted the recorded time-series sensor data into continuous wavelet transform scalograms and trained a Convolutional Neural Network to detect the freezing episodes. The proposed model achieved a generalisation accuracy of 89.2% and a geometric mean of 88.8%.
Deep 3D Dynamic Object Detection towards Successful and Safe Navigation for Full Autonomous Driving
Authors: Wijesekara Patikiri Arachchige Don Shehan Nilmantha
Published: January 2022

Infractions other than collisions are also a crucial factor in Autonomous driving since other infractions can result in an Accident. Most of the existing work has been tested for Navigation, collisions and least tested for other infractions such as off-road driving and not obeying road signs. We present an imitation learning based Base Model called CILDO and an optimized model of the base model optimized using an and additional traffic light detection branch and Deep Deterministic Policy Gradient based Reinforcement Learning called CILDOLI-RL. The proposed base model is designed to detect dynamic objects by developing the vision for semantic features, depth and motion which is crucial in Autonomous driving.

This paper proposes a new concise mathematical model of gear transmission dynamics with asymmetric load-dependent friction. It is built only upon the rigid-contact mechanics and the Coulomb friction law, but provides a new theoretical perspective on dynamic and static characteristics of gear transmissions. The presented model is of the form of a differential-algebraic inclusion (DAI) characterized by some parameters, including input-side and output-side asymmetry coefficients. The presented model properly captures the static friction and even the non-backdrivability. It is applicable to different classes of transmissions, such as leadscrew transmissions, worm gear transmissions, and spur gear transmissions. The DAI representation is extended into a multi-dimensional representation for articulated rigid-body systems driven through joint transmissions. Moreover, simulation algorithms are derived through the implicit Euler discretization. Some simulation examples illustrate the capability of the presented simulation algorithm to reproduce load-dependent asymmetric frictional behaviors, which cannot be reproduced by conventional load-independent joint friction models.

Capillary Electrophoresis and its Basic Principles in Historical Retrospect Part 1. The Early Decades of the “Long Nineteenth Century”: The Voltaic Pile, and the Discovery of Electrolysis, Electrophoresis and Electroosmosis
Authors: Kenndler Ernst , Minárik Marek
Published: January 2022

Here we set forth the first from a series of reports devoted to the history of capillary electrophoresis. In this opening part, we go more than two centuries back in time and revisit original discoveries of electrolysis, electrophoresis and electroosmosis. We emphasize the essential role of a brilliant invention of 1799 by Alessandro Volta, the Voltaic pile, basically the first battery delivering a constant-flow electricity, which has made all the scientific advances in the subsequent years and decades possible. We describe the experiments of William Nicholson and Anthony Carlisle revealing electrolytic decomposition of river water followed by enlightened investigations by Nicolas Gautherot, Ferdinand Frédéric Reuss and Robert Porrett that each independently and unaware of the works of the other uncovered the phenomena of electrophoresis and electroosmosis. We give not only a technical description and a chronological overview of the inventive experiments, but offer also some formidable details as well as circumstances surrounding some of the initial inventors and their observations. We conclude this time period, for which we coin the term "1st epoch of electrophoresis", with the same year 1914 as the coinciding period of European history termed the “Long 19th Century”, and accentuate the surprising fact that over this entire cycle of 125 years no attempts were taken to utilize the findings and newly acquired knowledge to perform an electric driven separation of compounds from a mixture. In the field of electrophoresis and electroosmosis, it is rather the epoch of pure than of applied science.
History of Research on Antisense Oligonucleotide Analogs
Authors: Cohen Jack S.
Published: January 2022

In the search for novel therapeutics, antisense oligonucleotide (ASO) analogs have been a major focus of research for over 40 years.  They use the antisense strategy, namely they have a nucleic acid base sequence that is complementary to a portion of a specific mRNA that is produced in the cell, or to a viral RNA, in order to selectively inhibit gene expression. Oligonucleotides need to be chemically modified to stabilize them against hydrolysis by endogenous nucleases. Until now several phosphorothioate (PS) oligonucleotide analogs have been approved by the FDA for human use. This article seeks to provide a history of this subject to date.

Los modelos educativos en la actualidad han perdido vigencia, más cuando la educación se ha enfrentado a una transición de la educación presencial a la educación mediada por tecnologías, para la cual nadie estaba preparado; las secuelas de la pandemia del COVID-19 (SARS-CoV-2), han dejado huellas imborrables en el devenir histórico de la humanidad; los sistemas han tenido que re-inventarse sobre la marcha y ajustar a nuevas estructuras para dar continuidad a los procesos de formación y capacitación; de allí emerge el objetivo del presente aporte: generar un compendio teórico – práctico de pedagogías emergentes y de educación 4.0 para la constitución de un modelo de enseñanza holístico en función al mejoramiento académico de estudiantes universitarios de la Facultad de Ingeniería de Sistemas de la Universidad Francisco de Paula Santander Ocaña. Investigación enmarcada en los métodos mixtos, (cuantitativo – cualitativo), desarrollado en tres momentos: primer momento documental, segundo momento entrevista semiestructurada para docentes y el tercer momento encuesta a estudiantes. Reflejado a través de redes neuronales artificiales (perceptron multicapa), y el algoritmo de entrenamiento packpropagation; junto con la curva ROC (receiver operating characteristic curve) utilizando el software SPSS. Los resultados obtenidos dejan evidenciar que las pedagogías emergentes y la educación 4.0 se convierten en una metodología pedagógica innovadora.

Objective: To evaluate the association between asthma prevalence and serum levels of vitamin D in Brazilian adolescents. Methods: This was a cross-sectional, school-based study involving adolescents between 12-17 years of age from four large Brazilian cities located at different latitudes (Fortaleza, Rio de Janeiro, Brasília, and Porto Alegre). Information on asthma diagnosis, lifestyle, and sociodemographic characteristics was collected by means of self-administered questionnaires. Serum concentrations of calcifediol were dichotomized as sufficient (= 20 ng/mL) or insufficient/deficient (< 20 ng/mL) levels. Bivariate analyses were carried out between vitamin D levels and prevalence of active asthma (AA), as well as other variables in study, using the chi-square test. Generalized linear models were configured to analyze potential confounding factors (p < 0.20). Results: Between 2013 and 2014, 1,053 adolescents were evaluated. The prevalences of AA and insufficient/deficient levels of calcifediol were 15.4% and 21%, respectively. There were no statistically significant associations between AA and hypovitaminosis D. The prevalences of AA and vitamin D insufficiency were, respectively, 2.34 (95% CI, 1,28-4.30) and 3.22 (95% CI, 1.75-5.95) times higher in Porto Alegre than in Rio de Janeiro, regardless of possible confounding factors. However, no significant associations were found between the prevalence of AA and vitamin-D-related variables in any of the cities. Conclusions: No association was found between AA and low levels of vitamin D in adolescents living at different latitudes in Brazil.
من مظاهر توظيف القراءات القرآنية في المعاجم العربية أثر اختلاف البنى في تعدد المعاني المعجمية - بحث في معجم لسان العرب
Authors: أسود م.د قاسم محمد , سعيد م.د محمد قاسم
Published: January 2022

لقد كان القرآن الكريم ولا زال محورًا لدراسات متعددة وأساسًا لانطلاق كثير من العلوم العربية والإسلامية، ولسان العرب هو ذلك المعجم اللغوي المشهور الذي ألفه ابن منظور في القرن السابع الهجري لِحفْظِ أصول اللغة وضبط بنْيَتهَا، إذ عليها مدار أحكام الكتاب العزيز والسنة النبوية. ويتميز هذا المعجم باعتماده الكبير على القراءات القرآنية فيما يقدمه لنا من دلالات اللغة وقواعد النحو وبلاغة التعبير. وهذا البحث محاولة لإظهار قضية القراءات القرآنية وكيف ترد في لسان العرب كشاهد على جواز التعبير بأكثر من شكل، ومدى استفادة اللغة من تنوع القراءات وما تضيفه القراءة الثانية أو الثالثة أو حتى السابعة من معانٍ جديدة تسهم في إثراء الفكر وتزيد من خصوبة اللغة وثرائها.

وبعد: فأقول: إنَّ هذا البحث محاولة مخلصة لوضع لبنة في صرح المعرفة الإنسانية الشامخ فإن أكن قد وفقت فذلك فضل الله يؤتيه من يشاء، وإن تكن الأخرى فحسبي صدق المحاولة والإخلاص لها والله من وراء القصد.
