The Effect of Using Ethyl Alcohol Extract of Ginger and its Juice on Some Contaminating Microbes of Cow Milk
No full textThe study has been conduct to investigated effect of ethyl alcohol extract and its juice on some contaminating microbes cow milk such as, Escherichia colli , salmonella typhimurium, Pseudomonas fluorescens that have pathogen and spoiled effect on caw milk. The study has been carried out at College of Agriculture / University of Baghdad cooperation with Biotechnology and Research Center / University of Al-Nahrin. Concentrations of 1,2,3,4,5,10,20,30,40,50 % ethyl alcohol and ginger juice are prepared. Result show a positively inhibition correlating with concentration, being the halo diameter for S. typhimurium at 10 to 50 %concentration (11.19, 12.13 ,12.62 ,13.31 ,14.11 mm respectively). E. coli whereas its effect on are 8.96 , 10.90 , 11.37 , 12.12 , 12.56 mm for the same above concentration . On other hand, its effect on P. fluorescens, has tended to be lower value that is the concentration 10 to 50 % are 7.11 , 8.42 ,9.15 , 10.83 ,11.21 mm respectively. There is no significant effect on bacteria attributed the low concentration ( 1, 2 %). It has appear of that similar previous results when using sterilized by microbe filters. Inhibition is significantly increased by increasing concentration 5% probability . The results are not juice instead of extract and they are significant increment also with increasing the concentration in both sterilizing method. Hala diameter inhibition for filter sterilizing with 3% concentration are 0.00 ,2.01 and 3.3 mm for the three bacteria type respectively , while hala diameter inhibition with 50% concentration are 9.37, 11.91 and 12.70 mm for the three types respectively. Ginger juice which sterilized by autoclave for 3% is 0.00 mm while hala diameter inhibition with 50% are 8.29, 10.59 , and 11.35 mm for the three bacteria types respectively . Statistical analysis show significant differences in the effect of concentration between bacterial types for each concentration . In conclusion, the ginger extract and its juice have an inhibition effect on milk contaminating bacteria using 2%concentration. This effect is positively correlated with increasing concentrations for both mentioned matters
Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.
No full textIFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells
Measuring industry-science links through inventor-author relations: A profiling method
No full textIn this pilot study we examine the performance of text-based profiling in recovering a set of validated inventor-author links. In a first step we match patents and publications solely based on their similarity in content. Next, we compare inventor and author names on the highest ranked matches for the occurrence of name matches. Finally, we compare these candidate matches with the names listed in a validated set of inventor-author names. Our text-based profile methodology performs significantly better than a random matching of patents and publications, suggesting that text-based profiling is a valuable complementary tool to the name searches used in previous studies.innovation; industry-science links; text-based profiling;
Critical edition of Muhammad Al-Tayyib's manuscript "Travel to Hijaz" : annotated and authenticated
No full textOne of the outstanding scholars of the field of Moroccan travel literature was Muh?ammad b. Muh?ammad al-T?ayyib b. Muh?ammad b. Musa b. Muh?ammad al-Sharqi al-Sumayli, al-Fasi al-Madani. Born in the city of Fez in 1110/1698. He studied with some of the most known scholars of Morocco at that time including Abu al-cAbbas Ah?mad al-Misnawi, Abu cAbdullah Muh?ammad al-Misnawi, Abu al-cAbbas Ah?mad al-Fasi and Abu T?ahir Muhammad al-Kurani. Having acquired his early education in his home country he emigrated eastward to Tunisia, Libya, Egypt and finally to Medinah where he died in 1170/1756 after living and teaching there for many years.It is not surprising then that this great scholar left behind him a treasure of works in a variety of fields; indeed we find Ibn al-T?ayyib wrote many works, including four in jurisprudence, three in h?adith and sixteen in grammar and in linguistics. Despite this however many of his academic contributions remain in manuscript form and therefore are inaccessible to the greater majority.One such work is “Rih?lah il a al-H?ijaz,” which is particularly important to the field of travel literature as it represents a major contribution. This is because Ibn al-T?ayyib came relatively late, historically, compared to other travel writers. In addition, it contains many minute details, which the author took care to record during his journey from place to place. It also contains accounts of everything he saw and his comments regarding the social, economic and political conditions of the countries he visited, as well as comments about the scholars whom he was able to meet. This work is important also because it is considered the most important reference for the author’s life, culture and is an important literary reference in terms of the poetry and prose, classical and modern, eastern and western, that it contains. In addition it accounts for both literary and religious scholars, the linguistic derivations of geographical names and draws attention to the mistakes of those who wrote about them before him. Bearing in mind the great significance of this work from a variety of aspects this thesis involves the complete revision, editing, annotation and authentication of the manuscript including the correction of missing characters and providing available information and biographical notes on the text
The Effect of Using Cooperative Learning Method in Enhancing EFL Students’ Performance in Speaking Skill in Libyan Universities: A Case Study of Benghazi University
No full textThis study aims to investigate the effect of using the Cooperative Learning Method in the EFL classroom to enhance students’ performance in speaking skill in Libyan Universities. This study endeavored to investigate how possible for EFL students’ performance in speaking skills can be augmented through Cooperative Learning Method. The author applied the quasi-experimental method, which was classified into two groups, an experimental group and a control group. 50 students were used as a sample for this study, and the sample was taken by using the purposive sampling method. The results indicated that the students obtained fair scores in the pre-test. After treatment, their speaking increased significantly. The results of the study were the mean score of students\u27 speaking skills obtained by the students through the pre-test was 46.24, and the post-test was 73. This means that there was an improvement in the speaking skill of the students after they received the treatment that was being taught. Through the use of the Cooperative Learning Method and also it could be seen the t-test value is greater than the t-table (-16.832>-9.765). This means that the null hypothesis (H0) is rejected, and the alternative hypothesis (H1) is accepted. The result of the analysis indicated that the use of cooperative learning was effective in improving students\u27 speaking skills, especially at the University of Benghazi in the academic year 2020/2021
al-Misbāh fī al-Nahw By Nāsir al-Dīn al-Mutarrizī al-Nahwī (d. 610/1213) A Critical Edition of the Text with the Life History of the Author
No full textNāsir al-Dīn al-Mutarrizī al-Nahwī (d.610/1213) was one of the most renowned figures in the field of Arabic Grammar. He has left an indelible mark on the world of Arabic language and literature. He is also known as the successor of al-Zamakhsharī.
He wrote a number of books but his al-Misbāh fī al-Nahw gained prominence at a level that no other book in this field could claim to achieve. For this reason, a great number of commentaries have been written in every age, of which the most famous are al-Daw and Khulāsat al-I‘rāb written by Tāj al-Dīn al-Isfrā’īnī and ‘Abd al- Karīm al-Tūsī (better known as Hājjī Bābā) respectively. Moreover, its translation into other languages also demonstrates its value as a useful book.
Although al-Misbāh has been edited on more than one occasion, the published editions do not fulfil the needs and requirements of modern academic research criteria. The basic aim of this thesis is to present this book with a current modern research style so that the students, teachers and ordinary readers of Arabic language and literature may benefit from this work.
This thesis is divided into two parts. The first part deals with the life history of the author and his other works. A brief note of the environment under which he grew up (generally referred to as the ‘Seljuk’ period) is also included in this part.
The second part consists of a text edition that deals with the derivation (Takhrīj) of syntactical issues together with the differing opinions of grammarians on syntactical/grammatical issues. This part also proffers the idiomatic English translation of al-Misbāh

No full textThis thesis is concerned with the work of al-Araj
al-Miski. fi t-Tärikh al-Makki by 'Ali b. 'Abd al-Qädir
at-Tabari. The work is one of the main sources'of Meccan
history, in particular during the eleventh century of
the Hijra/seventeenth century A. D.
Its author was one of the leading Meccan, scholars,
who held a number of religious posts in Mecca, and came
from a highly respected family of scholars, 'ulama'.
Part One is an introduction to the work and its
author. Chapter One deals with the authenticity of
this work and includes a biography of the author and a
description of his other works.
Chapter Two is a survey of the writing of Meccan
history until the author's time, which gives a brief
description of every work, and its place in the writing
of the history of Mecca. This helps to give the reader
a clear picture of the author's sources, and the place of
the present work in Meccan historiography.
Chapter Three is a study about the author as an
historian and his contribution to the history of Mecca.
In this chapter, the author's theory of history and the
historian's qualifications have been discussed, and whether
he applies them to himself or not. It also includes a
study of the author's plan and his use of his sources, and
finally a study of the importance of this work.
Chapter Four is a description of the manuscripts
which have been used in editing this work.
Part Two is the Arabic text of the work, together,
with the footnotes. The original copy of this work
seems to be lost, but three later copies containing the
first two-thirds of the work have been consulted. In
order to establish the correct reading of the work, the
author's sources and the later works which used this
work as a source have been consulted as well.
An attempt has been made to define people and
geographical places, and some difficult Arabic words, and
poetry, with the reference to relevant sources. Special
care has been taken to establish the correct reading of
some Qur'anic verses and some of the Prophet's traditions,
with the reference to the Holy Qur'an and some of the
Sihäh traditions

DNA fusion gene vaccination mobilizes effective anti-leukemic cytotoxic T lymphocytes from a tolerized repertoire
No full textThe majority of known human tumor-associated antigens derive from non-mutated self proteins. T cell tolerance, essential to prevent autoimmunity, must therefore be cautiously circumvented to generate cytotoxic T cell responses against these targets. Our strategy uses DNA fusion vaccines to activate high levels of peptide-specific CTL. Key foreign sequences from tetanus toxin activate tolerance-breaking CD4+ T cell help. Candidate MHC class Ibinding tumor peptide sequences are fused to the C terminus for optimal processing and presentation. To model performance against a leukemia-associated antigen in a tolerized setting, we constructed a fusion vaccine encoding an immunodominant CTL epitopederived from Friend murine leukemia virus gag protein (FMuLVgag) and vaccinated tolerant FMuLVgag-transgenic (gag-Tg) mice. Vaccination with the construct induced epitopespecificIFN-c-producing CD8+ T cells in normal and gag-Tg mice. The frequency and avidity of activated cells were reduced in gag-Tg mice, and no autoimmune injury resulted. However, these CD8+ T cells did exhibit gag-specific cytotoxicity in vitro and in vivo. Also, epitope-specific CTL killed FBL-3 leukemia cells expressing endogenous FMuLVgag antigen and protected against leukemia challenge in vivo. These results demonstrate a simple strategy to engage anti-microbial T cell help to activate epitope-specific polyclonal CD8+ T cell responses from a residual tolerized repertoire
