Mnemonic Effectiveness of CL-motivated Picture-elucidation Tasks in Foreign Learners‘ Acquisition of English Phrasal Verbs
Hussein Muhammadi Farsani,Ahmad Moinzadeh,Mansoor Tavakoli
Theory and Practice in Language Studies , 2012, DOI: 10.4304/tpls.2.3.498-509
Abstract: Learning the behavior/meaning of English phrasal verbs can prove challenging to the foreign language learner. This is mainly because such verbs, in their combinations with various prepositional/adverbial particles, often exhibit figurative senses not readily transparent to the learner. The absence of a culturally/socially rich experiential language setting giving rise to image-schematic patterns, as conceived in Cognitive Linguistic theory, might be an inhibiting factor in this regard. The present study takes this issue as its point of departure and examines whether pedagogical, picture-cued tasks revealing image-schematic concepts behind phrasal verbs would facilitate learners' inferences from their concrete to more abstract senses. It also aims to find out if such tasks would help enhance participants' acquisition and use of such verbs in the long run. For this purpose, 56 intermediate-level students aged 12-18 were randomly selected to go through the process of learning 42 phrasal verbs in an experimental or a control group each comprising 28 learners. Comparison of the results from the tests reveal a positive effect for picture-elucidation tasks – in contrast to more traditional use of discrete dictionary definitions – raising learners’ awareness toward image-schematic concepts behind English phrasal verbs. The study also carries implications for foreign language pedagogy as the tasks designed for the purposes of this study could be effectively used and further explored within the framework of Task-Based Language Teaching.
Ecology and Ethics: Some Relationships for Nature Conservation
Ahmad Abedi-Sarvestani,Mansoor Shahvali
Journal of Applied Sciences , 2008,
Abstract: These days, the reality of environmental crises creates grave doubts about the future of the natural environment. Many believe that if present human behavior toward the natural environment continues, there will be no hope for a sustainable life. Therefore, it is vital that human behavior toward nature be modified and corrected. Although, ethic is traditionally concerned about relations between individuals, but it is getting more attention for modifying human behavior in order to correct human-nature interaction and establish a well-intentioned one. In this respect, we need science of ecology and ethics together. Ecology helps us to understand natural ecosystems and respective regulations and laws, whereas ethics teach us how to define right and wrong behaviors toward the natural environment. This research discusses some possible relationships that might exist between ecology and ethics toward nature conservation.

English Language Teaching , 2010, DOI: 10.5539/elt.v3n4p132
Abstract: Textbooks play a very crucial role in the process of language teaching and learning. The present study carries out an evaluation of two series of ELT textbooks used for teaching English language in Iranian high schools from 1970 to the present. For this purpose, Tucker’s (1975) textbook evaluation model is employed. The results suggest that one of the main factors for the students’ achievement in English language is the ELT textbooks. The researchers suggest that in the textbooks, there should be enough opportunity for the learners to practice the language they are learning communicatively.
Local Descriptions of Roots of Cubic Equations over P-adic Fields
Mansoor Saburov,Mohd Ali Khameini Ahmad
Mathematics , 2014,
Abstract: The most frequently asked question in the $p-$adic lattice models of statistical mechanics is that whether a root of a polynomial equation belongs to domains $\mathbb{Z}_p^{*}, \ \mathbb{Z}_p\setminus\mathbb{Z}_p^{*}, \ \mathbb{Z}_p, \ \mathbb{Q}_p\setminus\mathbb{Z}_p^{*}, \ \mathbb{Q}_p\setminus\left(\mathbb{Z}_p\setminus\mathbb{Z}_p^{*}\right), \ \mathbb{Q}_p\setminus\mathbb{Z}_p, \ \mathbb{Q}_p $ or not. However, this question was open even for lower degree polynomial equations. In this paper, we give local descriptions of roots of cubic equations over the $p-$adic fields for $p>3$.

Abstract: various concentrations of aqueous leaf extract of lantana camara were assessed in vitro conditions against second stage juveniles (j2) of meloidogyne incognita. the standard concentration 's' of leaf extract was found to be highly nematostatic, where nematodes were completely paralyzed after 12 h and after 48 h of exposure, 96% of juveniles were killed at same concentration. however, the mortality of juveniles was 75% in s/2 dilution at 48 h. the degree of effectiveness and dilutions of extract were directly proportional. the percentage of paralyzed juveniles was decreased, when j2 transferred in distilled water after 48 h incubation in standard aqueous leaf extract. addition of freeze-dried aqueous extract to sterile sandy substrate at s/2 dilution significantly decreased the root-knot infection to susceptible eggplants whereas second stage juveniles (j2) that penetrated roots of eggplant were able to complete development in sterile sandy substrate without treatment of freeze-dried aqueous extract.
Standardization of Crude Extracts Derived from Selected Medicinal Plants of Pakistan for Elemental Composition Using SEM-EDX
Taous Khan,Mansoor Ahmad,Hamayun Khan,Waqar Ahmad
Asian Journal of Plant Sciences , 2006,
Abstract: The elemental analysis of crude extracts derived from selected medicinal plants of Pakistan, including Trichodesma indicum (whole plant), Paeonia emodi (aerial parts), Aconitum laeve (roots) and Sauromatum guttatum (corms, berries and leaves) was carried out using SEM-EDX technique. Various elements such as C, O, Cl and K were present in all tested plants` extracts, Al was observed in P. emodi and A. laeve, S was detected in T. indicum and S. guttatum (corms and leaves) while Mg and P were found only in S. guttatum (corms). The data showed that C was present in highest quantity in T. indicum and S. guttatum (leaves) (>80%) followed by O while in the rest of extracts these two elements were found in approximately equal quantities. The other detected elements were present in comparatively trace amounts. These results were also evaluated in correlations with previously reported biological activities of the tested extracts. This study would provide a new and alterative technique for the standardizations of crude extracts.
The Effect of Isoniazid (INH) on Erythrocyte Sedimentation Rate in the Lizard, Uromastix hardwickii
Mahmood Ahmad,Ruqaiya Hasan,Tazeen Naim,Mansoor Ahmad
Journal of Applied Sciences , 2003,
Abstract: Erythrocyte sedimentation rate of isoniazid treated lizard was worked out. The gradual decrease for day 5 to day 10 and day 15 was found to be statistically significant. This is indicative of increase in erythrocyte membrane permeability with increase in the span of treatment. Newer cells are flooded in the blood stream due to loss of older cells. Newer cell resist sedimentation on day 10 and day 15.

Abstract: Introduction: Cervical rib is a supernumerary rib springing from one of the cervical vertebrae, usually the seventh. About 1 in 200 people are born with cervical rib. About 1 in 10 people who have a cervical rib develop symptoms of thoracic outlet syndrome (TOS). Aims: The aim of this study was to identify normal and abnormal anatomy of thoracic outlet using MRI in symptomatic costoclavicular compression syndrome and to plan them for surgery thereafter. Methods: This was a prospective hospital based study. All the symptomatic cases of cervical rib syndrome admitted in the department of Cardiovascular and thoracic surgery SKIMS, Srinagar from May 2011 to May 2015 were taken up for the study. Results: A total of 40 cases of symptomatic cervical rib syndrome were reported from May 2011 to May 2015. Mean age of presentation was 26.3. The most prevalent age group was 21 - 30 years (47%). Majority of patients were females (83%) with male female ratio of 1:5. 67% had bilateral cervical rib, more in females (72%) than males (40%). 97% had neurogenic thoracic outlet syndrome and 3% had vascular thoracic outlet syndrome. 35% of cases with neurogenic thoracic outlet syndrome had subclavian artery compression on MR Angio of thoracic outlet after subjecting them to postural maneuvers. All the patients with subclavian artery compression were subjected to surgery. Conclusion: Costoclavicular compression syndrome affects mainly young females. MR Angio is complementary in finding vascular compression in cases presenting mainly with neurogenic symptoms of thoracic outlet syndrome.
Formal Modeling and Analysis of the MAL-Associated Biological Regulatory Network: Insight into Cerebral Malaria

Abstract: The discrete modeling formalism of René Thomas is a well known approach for the modeling and analysis of Biological Regulatory Networks (BRNs). This formalism uses a set of parameters which reflect the dynamics of the BRN under study. These parameters are initially unknown but may be deduced from the appropriately chosen observed dynamics of a BRN. The discrete model can be further enriched by using the model checking tool HyTech along with delay parameters. This paves the way to accurately analyse a BRN and to make predictions about critical trajectories which lead to a normal or diseased response. In this paper, we apply the formal discrete and hybrid (discrete and continuous) modeling approaches to characterize behavior of the BRN associated with MyD88-adapter-like (MAL) – a key protein involved with innate immune response to infections. In order to demonstrate the practical effectiveness of our current work, different trajectories and corresponding conditions that may lead to the development of cerebral malaria (CM) are identified. Our results suggest that the system converges towards hyperinflammation if Bruton's tyrosine kinase (BTK) remains constitutively active along with pre-existing high cytokine levels which may play an important role in CM pathogenesis.
