The vegan industrial complex: the political ecology of not eating animals
Authors: Trauger Amy
Published: October 2022

Many political ecologists and geographers study ethical diets but most are curiously silent on the topic of death in the food system, specifically what or who is allowed to live and what is let die in the "doing of good." This article aims to show how the practice of eating produces the socio-ecological harm most ethical consumers set out to avoid with their dietary choices. I examine the food systems that produce ethical products for 1) the hierarchical ordering of consumer health in the Global North over the health and well-being of workers in the Global South and 2) how vegetarianism involves the implicit privileging of some animals over others. The article takes take a genealogical approach to the political ecology of food ethics using Black and Indigenous studies in conversation with animal geographies. I draw on Mbembe's (2016) necropolitics, Weheliye's (2014) "not quite human" and Lowe's (2015) critique of humanism to develop a conceptual framework for what lives or dies as a result of ethical dietary choices. I use this framework to examine commodities for the socio-ecological harm that their production extends into the world under the guise of "doing good" or "being ethical." Taking a harm reduction and food sovereignty approach, I advocate for a new ethical framework that includes a limited case for consuming animals.
Long-chain polyunsaturated fatty acid supplementation increases levels in red blood cells and reduces the prevalence and severity of squamous gastric ulcers in exercised Thoroughbreds

Published: October 2022

OBJECTIVE

To assess the relationship between plasma and RBC fatty acid composition and incidence and severity of squamous gastric ulcers when altered by short-chain (SC) or long-chain (LC) polyunsaturated fatty acid (PUFA) supplementation.

ANIMALS

13 fit Thoroughbred horses in training.

PROCEDURES

Horses were evaluated by gastroscopy for squamous ulcer score, gastric pH, and blood fatty acid composition prior to supplementation (UNSUPP) and after 3 months of supplementation with a corn-flax oil blend of alpha-linolenic acid and linoleic acid (SC-PUFA) or a gamma-linolenic acid (GLA)-fish oil blend of GLA, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA; LC-PUFA) in a crossover design. Prior to gastroscopy and blood collection, horses performed a 4,600-m standardized exercise test on the racetrack as a stressor.

RESULTS

Three months of supplementation with LC-PUFAs increased RBC levels of GLA, dihomo-gamma-linolenic acid (DGLA), arachidonic acid (AA), EPA, and DHA, and reduced severe ulcer prevalence (38% UNSUPP vs 8% LC-PUFA with a severe ulcer score of grade 3 to 4). Short-chain PUFA supplementation did not effectively elevate RBC GLA, DGLA, AA, EPA, or DHA and severe ulcer incidence was not different (38% UNSUPP vs 23% SC-PUFA with a severe ulcer score of grade 3 to 4). Lower levels of RBC GLA, DGLA, AA, and EPA correlated with severe squamous gastric ulceration (grade 3 to 4).

CLINICAL RELEVANCE

Equine gastric ulcer syndrome is prevalent in high-performance horses and is a concern to owners and trainers. Long-chain PUFA supplementation increased levels of GLA, DGLA, AA, EPA, and DHA, unlike SC-PUFA supplementation, and was associated positively with prevention or resolution of severe squamous gastric ulceration. Further studies are needed to evaluate different management styles and exercise intensities.
Sexual dimorphism in structures, size and shape of the cyprinid Nilgiri melon barb, Haludaria fasciata
Authors: Chacko Judine John , Sekharan N Mini
Published: October 2022

The morphological differences between the sexes of a species is relevant to its captive breeding, ethology, and eco-biology and are studied extensively in fishes. In this paper, we analyzed the sexual dimorphism of the cyprinid Nilgiri melon barb, Haludaria fasciata (Jerdon), in their external structures, size, and shape. Physical examination, microscopical analysis, and morphometric and geometrical analyses of both sexes of the fish were conducted. The presence of tubercle pits and protuberant tubercles on the snout and orbital region were observed in males, while these were absent in females. Smaller-sized tubercles were arranged like a serration on the pectoral fin of males. Body size analysis indicated significant sexual size differences (P < 0.05) in body depth, fork length, eye diameter, pectoral fin length, and caudal fin length. Shape analysis indicated that the coordinate lengths L8 and L1 were the two that were significantly different (P < 0.05) between the sexes. In global redundancy trace analysis of vertices, the males in the population had more substantial variations in their shapes than did females. The paper discusses the possible functions linked with the dimorphic traits identified in H. fasciata.

Published: October 2022

The aim of the paper is to present the actual state of techniques regarding the influence of cryogenic cooling in turning and milling process.

Processing some materials is impossible without cooling the tool or the processed material. Hard-to-cut materials are increasingly used in industry, so new methods of cooling these materials had to be researched. Cryogenic cooling is the most efficient method to cool down the turning, milling or cutting tools. There are a lot of materials that are not affected by the low temperature of the liquid nitrogen (LN2), on the contrary, they behave better and have better proprieties after being cooled with LN2. On the other hand, there are materials that do not behave very well after cooling them with LN2 because their properties are changed, but with the right equipment, the amount of cooling liquid can be controlled, so that the temperature could be maintained at an optimal level.

This paper highlights the advantages of the cryogenic cooling systems compared to the classic cooling systems (cooling and lubricating in the same time) industrially used.

Published: October 2022

A 59-year-old woman presented with flushing attacks accompanied by tachycardia and hypotension, which lasted approximately 30 to 60 minutes, underwent 18 years ago a gastrointestinal tumor resection. The histologic examination revealed a poorly differentiated mixed neuroendocrine/adenocarcinoma located in the caecum with regional metastases. Postoperatively, the patient received combined chemotherapy of 5-fluorouracil with interferon for six months and since has remained asymptomatic. Her examination revealed positivity for chromogranin A (CgA) and a-Fetoprotein (aFP) (580 ng/24 h, normal range 27–94, and 10 IU/mL, normal range 0–6, respectively). Urinary 5-hydroxy indole acetic acid excretion was remarkably high (41.8 mg/24 h, normal range 2–10 mg/24 h). An abdominal Magnetic Resonance Imaging scan revealed multiple focal loci in the liver whose histological examination revealed a carcinoid tumor confirmed by an Octreoscan. Additional uptake was noted on the right shoulder and the right sternum-clavicle joint confirmed by Tc-99m MDP scan. The patient received somatostatin analogue therapy followed by long-acting release octreotide analogue therapy (30 mg/month) showing a partial improvement of relevant biomarkers. Two years later, carcinoid syndrome symptoms reappeared and due to the tumors expression of somatostatin receptors the patient received peptide receptor radionuclide therapy with 177Lu-DOTATATE that resulted in both clinical and biochemical improvements.

Authors: Yayla Fidan Bural
Published: October 2022

Subject and purpose of work: This study was designed in order to examine domestic practices of local female academics and to determine to what extent and how these practices affect business life.

Materials and methods: In the research phenomenological research design, one of the qualitative research methods, was used. The study group of the research consisted of 20 female faculty members from Turkey.

Results: Within the scope of the research, it was concluded that female academics, like other women in the society, undertake a series of gender role-based responsibilities.

Conclusions: The results of the research reveal that even women who belong to a profession that requires a high level of education and shows a status in the society, such as academics, take on more responsibilities in home life than their male colleagues. This result also proves that education and status factors are not sufficient to invalidate gender roles and social patriarchy.
The Throttle Effect – Blower Fan Versus Exhaust Fan
Authors: Hansen Rickard
Published: October 2022

One of the risks connected to fires underground is the throttle effect which may cause unforeseen smoke spread. This paper investigates the throttle effect for a blower fan and an exhaust fan case in a mine drift. The aim of the paper is to perform a parametric study on the throttle effect, varying influencing parameters such as the heat release rate and fan flow velocity. Data from fire experiments in a model-scale mine drift and results from CFD simulations were used during the study. It was found that the differences between the two fan cases were significant both in magnitude and occasionally in direction. For the base cases the throttle effect as well as the backlayering were more severe in the exhaust fan case. When increasing the heat release rate to 116 kW an increasing backlayering resulted, but the throttle effect was found to increase for the exhaust fan case and decrease for the blower fan case. The throttle effect decreased in the blower fan case as the gas density decrease levelled off, but the flow velocity increased even further, causing an increase in the downstream mass flow rate. This finding was confirmed by similar experimental results in model-scale mine drifts. The resulting mass flow rate induced by the fire plume changes was found to be higher than the externally imposed increase of the fan flow velocity. When increasing the distance between the fire and the exhaust fan, the backlayering increased and the throttle effect decreased.
Finite Element Analysis of a Cutting and Hauling Mining Adapter
Authors: Virág Zoltán
Published: October 2022

A recently completed research focused on the development of a low-volume mining production and transportation prototype machine. By developing this new mining adapter, the number of machines used in the mine can be reduced. Its application in dimensional stone mining can reduce the expenses of mining companies. After the block stone has been cut around, the stone material can be moved with the machine. The cutting forces and power requirements are calculated for the chain speeds used in production. This paper shows the static stress analysis of two kinds of possible structures of the dimension stone mining adapter. Finite element analysis was used to determine the displacements and the effective stress distribution of the adapter.

Authors: Herbei Mihai Valentin , Herbei Roxana Claudia , Sala Florin
Published: October 2022

The aim of the study was to evaluate the phenomenon of land tilting and the tilting distance as a secondary effect of surface coal mining in the Jiu Valley area, Romania. To evaluate the tilting phenomenon, through the two considered elements (inclination – Lt, tilting distance – Td) 16 control points (CP1 to CP16) were used whose coordinates were measured in the Stereographic 1970 projection system, the 1975 Black Sea elevation system at an initial moment (t0) and at the current moment (t1). The static method was used by GPS technology to measure the elevations of the control points. Through descriptive statistical analysis, a general characterization of the set of recorded values was obtained, and the ANOVA test confirmed the safety of the data and the presence of variance in the data set. From the analysis of the recorded values, a Spline type model was obtained that described the variation of Lt in relation to Td, under conditions of statistical safety ( ɛ¯ = 0.137302). Regression analysis facilitated the obtaining of equation-type models, which described the variation of Lt and Td in relation to the X, Y and Z coordinates of the control points (t0, t1), under conditions of statistical certainty (R2 = 0.697, p=0.014 for Td variation according to Z0 and Z1; R2 = 0.722, p=0.0094 for Td in relation to X0 and Z0). According to PCA, PC1 explained 61.303% of variance, and PC2 explained 38.697% of variance. The cluster analysis facilitated the obtaining of a dendrogram based on Euclidean distances, regarding the grouping based on the similarity of the control points in relation to the studied phenomenon, under conditions of statistical safety (Coph. corr.=0.957).

Published: October 2022

As part of the company Geoscan Service S.R.L., I was contacted to investigate the possibility of using resistivity, refraction seismic data and MASW seismic to identify the stratification up to 15m deep so that the client could choose the type of drilling rig for installing the conductor in order to drill two water injection wells. The main problem in the choice of geophysical methods was the lack of detailed geological data for calibrating the obtained results, as the presence of groundwater, the thicknesses of the deluvial layer and the bedrock. The choice of geophysical methods and the work procedure are carried out according to the international standards in force, ASTM D6429-99 “Standard guide for Selecting Surface Geophysical Methods”, ASTM D5777-00 “Standard guide for Using the Seismic Refraction Method for Subsurface Investigation, “Standard Guide for Using the Direct Current Resistivity Method for Subsurface Site Characterization”, STAS 1242/7-84 “Geophysical research of the land by seismic methods”.
Aspects Regarding the Use of Coal in the Production of Electrical and Thermal Energy
Authors: Bobei Vasile , Ciolea Daniela
Published: October 2022

Globally, coal was and remains one of the main primary energy resources, being the cheapest option for power generation. Coal deposits are available in large quantities, its exploitation being done with more stable prices and less sensitive to a series of international events, but it has the disadvantage of significant additional costs, due to the technologies required to reduce emissions in the environment. Romania, one of the most important coal-producing countries in Europe, has a long tradition in the mining industry and has important coal reserves, which can ensure the continuity of production for more than 150 years. Unfortunately, after 1989, coal production in our country almost halved, mainly due to the decrease in mining activity and the reduction of coal consumption (both by industry, such as steel and households - for the heat consumed from power plants based on of coal). At the moment, Romania mainly imports coal, but the share of imported coal also decreased to a quarter compared to 1990.
Effect of elevated pressure on gas-solid flow properties in a powder feeding system
Authors: Ren Guanlong , Sun Haijun , Xu Yihua , Li Chao
Published: October 2022

In view of the powder feeding system, a multi-physical coupling model of the gas-powder-piston was established based on the Euler-Euler two-fluid model. The numerical simulation method was applied to explore the effects of dense gas-solid flow characteristics under different operating pressures. The results show that gas-solid pulsations at different operating pressures are mainly concentrated in the upper part of the powder tank. An elevated operating pressure efficiently decreases the powder layer area (εp = 0.1) fluctuation. As the operating pressure increases from 0.5 MPa to 3.0 MPa, the rising time and fluctuation rate of pressure are reduced by 71.4% and 62.3%, respectively, and the pressure in the tank has a long stabilization period. Meanwhile, the variation of the instantaneous powder flow rate is more stable and its average value is closer to the theoretical. A high-pressure environment is more conducive to the stable transportation of powder.
Neutrophils in the pathogenesis of rheumatic diseases
Authors: Loh Jia Tong , Lam Kong-Peng
Published: October 2022

Rheumatic diseases, including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), are a group of auto-inflammatory disorders associated with substantial morbidity and mortality. One unifying feature of these diseases is the presence of abnormal neutrophils exhibiting dysregulated neutrophil extracellular trap (NET) release, reactive oxygen species (ROS) production, degranulation, and pro-inflammatory cytokines secretion. Moreover, the release of autoantigens associated with NETs promotes the generation of autoantibodies and a breakdown of self-tolerance, thereby perpetuating inflammation and tissue injury in these patients. In recent years, targeted therapies directed at neutrophilic effector functions have shown promising results in the management of rheumatic diseases. In this review, we will highlight the emerging roles of neutrophils in the onset and progression of rheumatic diseases, and further discuss current and future therapeutic approaches targeting the pathogenic functions of neutrophils, which can modulate inflammation and hence improve patients’ survival and quality of life.

Published: October 2022

ABSTRACT Debonding between post and resin cement often occurs due to inadequate smear layer removal.Currently, the wide use of Chitosan as an alternative irrigating solution can remove the smear layer. This studyaimed to determine the effect of 0.2% chitosan high molecule nanoparticle (CHMN) on the push-out bond strength ofresin cement in post-restoration and types of adhesion failure using the different irrigating solutions. Endodontictreatment was performed on 24 mandibular premolars, which were divided into four groups, namely group 1: 0.2%CHMN, group 2: 2.5% sodium hypochlorite (NaOCl) and CHMN, group 3: 5.25% NaOCl and CHMN, group 4: 2.5%NaOCl and EDTA 17%. The final restoration was done using prefabricated glass fiber posts, and each sample wassliced into three segments transversally with a thickness of 2 mm. A push-out test was performed with a universaltesting machine, and failure modes were observed under a stereomicroscope. Data were analyzed with a one-wayanalysis of variance (ANOVA), LSD, and Kruskal-Wallis tests. The results showed a significant difference in pushoutbond strength of resin cement in post-restoration between all groups. The Kruskal-Wallis test showed nosignificant difference between types of adhesion failure. In conclusion, 0.2% CHMN affects the push-out bondstrength of resin cement in post-restoration regardless of or without a combination of NaOCl. However, there wereno effects on the types of adhesion failure. Keywords: bond strength, 0.2% chitosan solution, endodontic irrigation, fiber post

Authors: STEPANINTA Stepaninta , ANDRYAS Ika
Published: October 2022

The temporary crown must meet the patient's aesthetic needs even if it is used only for a while,especially gloss. It is believed that composite resin does not produce odor but shows minimal shrinkage, lower heatgenerated during polymerization, and is more aesthetically pleasing. Therefore, this material is one of the choices sothe clinicians can improve the patient's aesthetic needs. Nowadays, people demand clean and whiter teeth. Brushingwith whitening toothpaste is believed to affect the surface of the composite resin. The design of this study was alaboratory experiment. The sample in this study was a temporary crown material of acrylic resin and selfpolymerized composite resin with a sample size of 26 mm x 26 mm x 2 mm. All samples were tested using a gloss meter, followed by univariate statistical analysis to determine each group's mean gloss value and standard deviation. The research was continued using Wilcoxon statistical analysis to determine the difference in each group's temporary crown material gloss value. The results showed a significant difference in all temporary crown materials gloss value before and after brushing with whitening toothpaste. The conclusion of this study state that the composite resin material group has a better gloss value than acrylic resin material. Composite resin can maintain gloss value at gloss standard, even after brushing with abrasive toothpasteKEYWORDS: Temporary crown, Gloss, Gloss Meter
PRICE STRATEGIES IN ROMANIA’S WINE MARKET
Authors:   Bucharest University of Economic Studies, Romania, RĂDULESCU Carmen Valentina , POPESCU Maria Loredana ,   Bucharest University of Economic Studies, Romania
Published: October 2022

Romanian wine producers/sellers face today – as in any other European (market) economy – challenges specific to such merchandise as alcoholic beverages, of which wines are a part, which, unlike (almost) any other type of product, can destroy consumers and therefore alter the very fabric of consumption process and mechanisms. These consumption limitations take their toll on any wine producer (or seller)’s capacity of profit maximising and can only add to the effects of a powerful foreign competition – which, in Romania, is more than ‘able’ to monopolise selling of most expensive wines –, and of the very reality Romania is (in relative terms) so poor a country that average level of consumers’ revenues simply cannot ‘insure’ – not for all, that is – profit maximising concept turning into reality. For all these reasons, a price strategy in the Romanian wine market is both indispensable and challenging.

Among them, 36.1% knew that FA is vitamin B. Only 75 (19.5%) females reported getting the proper daily amount of FA (400 mg/day), and 216 (56.1%) knew that FA should be given before and during the first trimester of pregnancy. Regarding the effects of FA deficiency, 51.2% of females reported FA deficiency anemia. Only 22.1% of females said they had heard of neural tube defects.
Conclusion: This study concluded that the female population's knowledge regarding FA is poor. Authors suggest using social media and awareness campaigns to improve the understanding and knowledge of FA among Saudi female people.
Internal Carotid Artery Agenesis Associated with Contralateral Posterior Communicating Artery and Basilar Tip Aneurysms: A Case Report
Authors: Hafiz Badr , Barnawi Hassan , Almulhim Ibrahim , Alharbi Mohammed , Alturki Abdulrahman
Published: October 2022

Background: The absence of the internal carotid artery is an extremely rare congenital anomaly with a reported incidence of 0.01%. As with other anatomical vascular variants, they usually follow a silent course and are typically discovered incidentally.
Case Presentation: We report an unusual case of a 30-year-old male medically free who presented to the emergency department with sided numbness involving both upper and lower limbs while he was swimming. Brain imaging revealed a congenital absence of the right internal carotid artery in association with basilar tip saccular aneurysm and right posterior communicating artery aneurysm. The patient was treated successfully with endovascular stent-assisted coiling of the basilar artery and stenting of the right posterior communicating artery.
Conclusion: The main significant impact that this condition harbors is the high association with intracranial aneurysms secondary to hemodynamic stress on other intracranial arteries with compensatory increased flow. This case report supports this hypothesis and shows complex endovascular management.

Background: The third most common skin condition worldwide is acne vulgaris. This condition affects both sexes, with peak prevalence among teenagers and young adults. This study aimed to assess the attitude and behavior of the participants regarding acne and its treatment, and to identify the factors that affect the knowledge, practice, and attitude among adolescents and adults.
Methods: A cross-sectional study was conducted involving 1,134 participants in Saudi Arabia between January 7 2021 and February 20 2021. An electronic-based questionnaire of 53 questions was used to collect data from people in Saudi Arabia. Data were analyzed by Statistical Package for the Social Sciences 25. The chi-square test was used to determine the association between qualitative variables.
Results: Multiple factors play a role in malpractice and bad attitudes: educational, financial, and cultural. The data show poor knowledge about acne vulgaris, especially for those younger than 21 years old, as they present just above half of the participants with poor knowledge (50.8%); at the educational level, those who had the highest percentage of good knowledge were postgraduates (52.3%), and the highest percentages of poor knowledge were the participants with high-school-level education (65.3%). As for knowledge, the internet was the source that our participants relied on (58.9%), followed by doctors, relatives, and friends.
Conclusion: This study indicates poor knowledge and malpractice toward acne vulgaris among the Saudi Arabian population. The data provide a benchmark on the general level of knowledge, attitude, and practices, which can be used to formulate an awareness program.

A Study On Twenty First Century Cyclones and Their Lifetime Behavior in The Bay of Bengal
Authors: Towhiduzzaman Md. , Al Mohit Md. Abdul , Rahman Md. Atikur
Published: October 2022

Bangladesh is a small disaster prone country in South Asia. The natural hazards of this country increased due to global warming.  An informative investigation of cyclone lifetime activity within the Bay of Bengal has been in Analyzed. Cyclone characteristics, mainly lifetime, occurrence were investigated with 21st century cyclone data calibration. The changes of cyclone characteristics were investigated from the Bangladesh Meteorological Department data. The data are observed by their own technology. A statistical and mathematical estimation was performed to investigate the trend and make a best fit of the cyclone behavior line. Major fitted curves are spline, shape-preserve, cubic, quadratic and linear. A significant change of the characteristics has been found due to change of time, which plays a vital role in changing the surge behavior and associated environmental parameters within this area. An increasing trend of occurrence behavior has been found from this study. Significant information comes from this study and the information is about the lifetime of a cyclone. Although the lifetime of cyclones fluctuates due to changes in climate conditions, the lifetime of cyclones will increase in the future. This means that the future cyclone gathers more energy and power. So that, in near future Bangladesh will face more powerful cyclone hazards.

إيمان السحرة في القرآن الكريم / دراسة مقارنة
Authors: Abdul-Jabbar Noah Zarnan
Published: October 2022

تتلخص فكرة هذا البحث في تفسير الآيات القرآنية التي تتناول الحديث عن السحرة الذين ذكرهم القرآن الكريم فقد كانوا يعيشون في عهد فرعون ولما دعا  موسى u  فرعون ،وقومه للإيمان بالله تعالى وحده ،وبدينه الحق وأظهر لهم المعجزات الدالة على صدقه في دعواه  ظن فرعون أن ما جاء به موسىu  سحر فاستعان بأولئك السحرة لمواجهة موسىu   ،وإبطال ما جاء به من الدين الحق فظهر الحق على يد موسىu  وبطل سحر السحرة ؛ فآمن السحرة بدين الله مما جعل فرعون يتهمهم بالتآمر مع موسىu  ضده ،وضد القبط ويهددهم بأشد أنواع العذاب الا انهم لم يتراجعوا ،ودعوا الله تعالى أن يصبرهم ،ويثبّتهم ويتوفاهم على الدين الجديد.
علم التفسير عند محمد نووي الجاوي (ت: 1316هـ) من خلال تفسيره ( مراح لبيد لكشف معنى القرآن المجيد )
Authors: Ghadban Sarah Jamal Khalaf , Karim Qais Jalil
Published: October 2022

إن علم التفسير علمٌ واسعٌ وهو من أجل ِ العلوم وأشرفها على الإطلاق كيف لا ! وهو المبينُ لمرادِ الله سبحانه وتعالى من كتابه الكريم ,  ولهذا فقد بسط َ العلماء  أقوالهم في هذا العلم  ولا حدود لإجتهاداتهم في تعريفه فكل عالم يعرفه بما يراه مناسبا ً ودقيقا ً وقريبا ً من المعاني القرآنية ,وينظر من زاوية تختلف عن زاوية آخرى قد يراها مفسر آخر انها أكثر ُ دقة ً وتصويبا ً, فقالوا في علم التفسير : هو علم نزول الآية وسورتها, ثم ترتيب مكيها ومدنيها , ومحكمها ومتشابهها ,ومقيدها ومجملها , وعامتها وخاصتها, وقالوا ايضا ً : هو علم ُ حرام السورة وحلالها ووعدها ووعيدها ,وعبرها وأمثالها ونهيها .
أما الجاوي ( رحمه الله ) فلم يصرح في تفسيره بتعريف لغوي أو إصطلاحي (للتفسير ) ولكن ! إستطعنا أن نستنتج ذلك من خلال تفسيره للآيات التي وردَ فيها هذا اللفظ فقد ذكر ان التفسير هو الكشف والبيان وهو مرادف للمعنى اللغوي له ,  وقد ذكر َأوجه التفسير وهو ما أثر عن ابن عباس ( رضي الله عنه ) حيث ذكر ان اوجه التفسير أربعة هي : تفسير تعرفه العرب من كلامها,  وتفسير  لا يعذر أحد بجهالته , وتفسير لا يعلمه الا الله , وتفسير يعلمه العلماء .
اما في الألفاظ التي تحتمل أكثر من معنى فإنه يذكرها  سواء كانت في موضع واحد أو في عدة مواضع فهو لا يخرج عن ما قرره جمهور العلماء في هذا الباب .
اما عن أنواع التفسير من حيث مصادره فقد إنقسمت الى التفسير بالمأثور : وهو كل جاء في القران الكريم او في سنة الرسول  ( ÷) ,أو في كلام الصحابة والتابعين وكان مبينا ً لمراد الله تعالى من كتابه , فهو بذلك يشمل تفسير القرآن بالقرآن , وتفسير القرآن بالسنه , وتفسير القرآن بأقوال الصحابة والتابعين , والجاوي ( رحمه الله ) قد أكثر من هذا النوع من التفسير في كتابه , بالإضافة الى التفسير بالرأي : وهو اجتهاد المفسر ببعض القواعد التي يحتاج اليها المفسر, فقد غلب َ هذا النوع من التفسير على تفسير الجاوي ولا سيما انه أقتبسه من تفسير الرازي الذي يعتبر تفسيره من أهم كتب التفسير بالرأي.
