A Pragmatic Analysis Of Love Expression Reflected In The Last Promise Novel By Richard Paul Evans
This study deals with the linguistic form of love expressions in the last promise novel, the illocutionary meaning of love expressions in the last promise novel, and the politeness strategy of love expression in the last promise novel. The type of this research is descriptive qualitative research in which the object is love expressions in The Last Promise novel by Richard Paul Evans. In collecting data, the writer uses documentation method. The data were the written text of love expression utterance used in The Last Promise novel. The data of
variations of linguistic form were analyzed by Marcella Frank, the illocutionary meanings were analyzed by Austin, and the politeness strategies were analyzed by Brown and Levinson. The result of the study shows that, (1) there are three variations of linguistic form for love expressions, they are declarative sentence (I wanted to do something special for you), interrogative sentence (how about if we just hug?), and imperative sentence (promise me you will never leave me again). (2) there are six illocutionary meaning of love expressions, namely showing affection (I love you Eliana, with all my heart I love you), showing care (but, be careful), showing engagement (I will always love you), showing persuasion (have you ever seen a
moon like that?), showing eagerness (I want to be alone with you), expressing compliment (you have beautiful hands). (3) there are three types of politeness strategies for love expression, they are Bald on record strategy (I won’t leave him), Positive politeness strategy (I’m glad you came to Rendola, Ross), Negative politeness strategy (I didn’t mean to hurt you)
Effect of Different Plant Growth Regulators on Callus Induction from Seeds of Chickpea (Cicer arietinum L.)
The present study was undertaken to develop a reproducible protocol for efficient in vitro callus initiation of chick pea (Cicer arietinum L.). The main objectives of this present study were to develop the optimal concentrations and combination of auxin and cytokinin for optimized callus induction from seeds as explants. Callus induction was initiated from seeds on MS media supplement, which varied according to the plant growth regulators treatment. Among the growth regulator combinations the highest rate of callus induction (85%) was observed in MS medium containing 2 mg L -1 of 2,4-Dichlorophenoxyacetic Acid (2,4-D), 2 mg L -1 Benzylaminopurine (BAP) showed higher percentage ( 63% ) of callus formation than 1- Naphthaleneacetic acid (NAA), which produced 49% of callus. There were significant differences in percentage of calli fresh/dry weights (g/jar) on the different initiation ( seven) medium used were the MS+2,4-D, MS+2,4-D +NAA+ BAP and MS+ BAP had the highest fresh/dry weights (g/jar) in both induction medium
Adsorption Study of Rhodamine –B Dye on Plant (Citrus Leaves)
تتضمن الدراسة الحالية امتزاز صبغة الرودامين B على سطح اوراق النارنج باستخدام تقنية مقياس الأشعة الفوق البنفسجية حيث تم تحديد البيانات الكمية للامتزاز (زمن التلامس، القوة الأيونية، درجة الحموضة، ودرجة الحرارة). تمت دراسة تأثير درجة الحرارة على عملية الامتزاز عند النطاق (25، 35، 45، و55) درجة مئوية حيث أظهرت النتائج بأن عملية امتزاز الرودامين B على مسحوق اوراق النارنج تزداد بزيادة درجة الحرارة مما يدل على أن عملية الأمتزاز عملية ماصة للحرارة. وبأستخدام تراكيز مختلفة من محلول كلوريد الصوديوم تم دراسة تأثير القوة الأيونية على عملية الأمتزاز.فقد ثبت أن زيادة القوة الأيونية تعمل على تحسين كمية أمتزاز رودامين B على أوراق النارنج عند درجات حرارة ثابتة. وأعطت النتائج أن كمية أمتزاز صبغة الرودامين B تزداد بزيادة PH للمحلول في المدى (3-7). ثم خضعت نتائج دراسة الامتزاز لنماذج متساوي الحرارة Freundlich , Langmuir و Temkin ، حيث تم تحديد معاملات كلا من Langmuir و Freundlich و Temkin ، ووجد أن متساوي الامتزازيخضع إلى متساوي الحرارة . Temkin ,Freundlich تمت أيضًا دراسة المعاملات الديناميكية الحرارية (مقدار التغيير في المحتوى الحراري ، ومقدار التغيير في الانتروبيا ومقدار التغيير في الطاقة الحرة لـ Gibbs) ووجد أن النتائج الديناميكية الحرارية لعملية امتزاز صبغة Rhodamine-B على مسحوق أوراق النارنج ماصة للحرارة وعملية الأمتزازعملية تلقائية.The current research includes the adsorption of Rhodmine-B Dye on the surface of Citrus Leaves using the technique of UV. Vis spectrophotometer to determine data of quantitative adsorption at various contact time, ionic strength, PH and temperature conditions. As a function of temperatures 25,35,45,55 0C, the dsorption phenomenon was examined, and the results showed that Rhodamine-B adsorption Citrus leaves rose with increasing temperatures on the surface (endothermic process). Using various NaCl solution concentrations, the effect of ionic strength on adsorption has also been studied. Increasing the importance of ionic strength has been shown to improve the amount of adsorption of Rhodamine-B on citrus leaves at constant temperatures.The quantity of Rh-B dye that was adsorbed on the citrus leaves was increased with increasing the PH of the solution in rang 3-7. Then the results were subjected to the practical results obtained with the use isotherms of the Langmuir, Frendelsh, and Temkin. The results can be shown that the isotherm suitable for adsorption applies to Ferndelsh and Temkin. The thermodynamic functions (the amount of change in enthalpy, the amount of change in entropy and the amount of change in the free energy of Gibbs) were also studied, and it was found that the thermodynamic results of the adsorption process of the Rhodamine-B dye on the powder of citrus leaves are endothermic and an automatic adsorption process
Content analysis of crisis communicative strategies: Tunisian protest vs. anti-Mubarak protest
The paper explores the crisis communicative strategies (CCs) that the former Tunisian president, Zine El Abidine Ben Ali, and the former Egyptian president, Hosni Mubarak, used in response to the protests, which are considered as one of the most critical crises in their reigns. A content analysis was conducted to examine the three speeches each president delivered during the crisis event in order not only to protect their image but also to restore peace and order. The study aimed to address the following questions: What are the crisis response strategies they used to restore their (distorted) image? did these strategies change over the demonstration period? and are they appropriate to the crises? In so doing, the analysis probes the length as well as the number of words and sentences; the framing patterns that have been applied (logical vs. emotional), and the crisis communicative strategies applying Coombs’ (1999) communicative strategies model.
IBN ARABSHAH: THE UNACKNOWLEDGED DEBT OF CHRISTOPHER MARLOWE’S TAMBURLAINE
This thesis suggests strong relations between Marlowe’s Tamburlaine I & II and Ibn Arabshah’s 1436 account of Tamerlane’s Life (‘Ajaib al-maqdur fi nawa’ib Timur: The Wonders of Destiny Concerning the Calamities Wrought by Tamerlane), clarifies controversial issues, and explains previously baffling allusions editors have pondered long. In general, the thesis enriches our understanding of Marlowe\u27s wide ranging sources, implies a critique of western-biased source scholarship, and opens possibilities to re-evaluate eastern contributions to the Renaissance in general. The first chapter highlights some well-recognized events in the play and in historical sources (the caging of Bayazid and ill-treatment of his wife, the trampling of children- virgins under the hooves of cavalry), and some obscure and never before identified incidents in historical records (gold underwater and the Christians of Georgia). The second chapter treats the “scene of death” in Marlowe’s play and in Ibn Arabshah’s account; the third addresses the importance of astrology, especially stellar and planetary conjunctions in both works. The fourth proposes a source for Zenocrate stronger than any of those advanced so far
Dissolving microneedles for DNA vaccination: Improving functionality via polymer characterisation and RALA complexation
DNA vaccination holds the potential to treat or prevent nearly any immunogenic disease, including cancer. To date, these vaccines have demonstrated limited immunogenicity in vivo due to the absence of a suitable delivery system which can protect DNA from degradation and improve transfection efficiencies in vivo. Recently, microneedles have been described as a novel physical delivery technology to enhance DNA vaccine immunogenicity. Of these devices, dissolvable microneedles promise a safe, pain-free delivery system which may simultaneously improve DNA stability within a solid matrix and increase DNA delivery compared to solid arrays. However, to date little work has directly compared the suitability of different dissolvable matrices for formulation of DNA-loaded microneedles. Therefore, the current study examined the ability of 4 polymers to formulate mechanically robust, functional DNA loaded dissolvable microneedles. Additionally, complexation of DNA to a cationic delivery peptide, RALA, prior to incorporation into the dissolvable matrix was explored as a means to improve transfection efficacies following release from the polymer matrix. Our data demonstrates that DNA is degraded following incorporation into PVP, but not PVA matrices. The complexation of DNA to RALA prior to incorporation into polymers resulted in higher recovery from dissolvable matrices, and increased transfection efficiencies in vitro. Additionally, RALA/DNA nanoparticles released from dissolvable PVA matrices demonstrated up to 10-fold higher transfection efficiencies than the corresponding complexes released from PVP matrices, indicating that PVA is a superior polymer for this microneedle application
Efficient palm vein authentication encryption technique in wireless implantable medical devices
Implantable medical devices (IMD) are commonly utilized to treat chronic illnesses. Many IMD communicate in wireless mode using an external programmer, which raises security concerns. Security of IMD is a critical issue which assaults direct harm to patients. Many researches are carried out on IMD security and challenges when the patient is not in a critical situation. Still, it would be a major issue while the patient is unconscious. In this research, a novel scheme for emergency secure access control of IMD was proposed to improve the security of biometric-based IMD schemes. The proposed authentication scheme uses a combination of palm vein and zero-watermark to generate encrypted credential data for IMDs. Using quantitative assessment for evaluating images, such as the peak signal-to-noise ratio (PSNR), structural similarity index (SSIM), and the mean squared errors (MSE), the suggested framework is shown to be superior to existing methods. Two other study goals are improved efficiency and image quality at a lower computational cost
Systemic RALA/iNOS nanoparticles; a potent gene therapy for metastatic breast cancer coupled as a biomarker of treatment
This study aimed to determine the therapeutic benefit of a nanoparticular formulation for the delivery of inducible nitric oxide synthase (iNOS) gene therapy in a model of breast cancer metastasis. Nanoparticles comprising a cationic peptide vector, RALA, and plasmid DNA were formulated and characterized using a range of physiochemical analyses. Nanoparticles complexed using iNOS plasmids and RALA approximated 60 nm in diameter with a charge of 25 mV. A vector neutralization assay, performed to determine the immunogenicity of nanoparticles in immunocompetent C57BL/6 mice, revealed that no vector neutralization was evident. Nanoparticles harboring iNOS plasmids (constitutively active cytomegalovirus [CMV]-driven or transcriptionally regulated human osteocalcin [hOC]-driven) evoked iNOS protein expression and nitrite accumulation and impaired clonogenicity in the highly aggressive MDA-MB-231 human breast cancer model. Micrometastases of MDA-MB-231-luc-D3H1 cells were established in female BALB/c SCID mice by intracardiac delivery. Nanoparticulate RALA/CMV-iNOS or RALA/hOC-iNOS increased median survival in mice bearing micrometastases by 27% compared with controls and also provoked elevated blood nitrite levels. Additionally, iNOS gene therapy sensitized MDA-MB-231-luc-D3H1 tumors to docetaxel treatment. Studies demonstrated that systemically delivered RALA-iNOS nanoparticles have therapeutic potential for the treatment of metastatic breast cancer. Furthermore, detection of nitrite levels in the blood serves as a reliable biomarker of treatment. Keywords: nonviral gene therapy, nitric oxide, nanoparticle, breast cancer, metastasi
Synthesis Characterization and Biological Activity Study of New Schiff and Mannich Bases and Some Metal Complexes Derived from Isatin and Dithiooxamide
Two new Schiff and Mannich bases, namely, 1-Morpholinomethyl-3(1′ -N-dithiooxamide)iminoisatin (LIH) and 1-diphenylaminomethyl-3-1′-N-dithiooxamide)iminoisatin (LIIH), were prepared from condensation reaction of new Schiff base 3-(1′-N-dithiooxamide)iminoisatin (SBH) with morpholine or diphenylamine respectively in presence of formaldehyde . The structures were characterized by IR, 1HNMR, mass spectrometry, and CHN analyses. Metal complexes of the two ligands were synthesized, and their structures were characterized by elemental analyses, atomic absorption, IR and UV-visible spectra, molar conductivity, and magnetic moment determination. All complexes showed octahedral geometries except palladium complexes which were square planar. The biological activity of the prepared compounds and some selected metal complexes was tested against three types of bacteria and against cell line of human epidermoid larynx carcinoma (Hep-2)
