Growth and yield of rice as affected by transplanting dates and seedlings per hill under high temperature of Dera Ismail Khan, Pakistan     

Baloch MS  Awan IU  Hassan G 《Journal of Zhejiang University. Science. B》2006,7(7):572-579

Studies were initiated for two consecutive years to find out the effect of time of transplanting and seedlings hill^-l on the productivity of rice in Dera Ismail Khan district of North West Frontier Province （NWFP）, Pakistan. The experiment was laid out in a randomized complete block design with split plot arrangements. Main plots consisted of four transplanting dates viz. 20th and 27th of June and 4th and 1 lth of July while sub-plots contained 1, 2, 3 or 4 seedlings hill^-1. Among transplanting dates, June 20th planted crop gave highest paddy yield and net return with I seedling hill^-1. It explains that the use of more seedlings hill^-1 not only adds to cost but is also a mere wastage of natural resources. Based on research findings, we conclude that the use of I seedling hill^-1 is most appropriate for timely sowing otherwise 4 seedlings hill^-1 should be used to compensate for the yield gap in late transplanted rice.  相似文献   

Temperamental Shyness,Frontal EEG Theta/Beta Ratio,and Social Anxiety in Children     

Kristie L. Poole  Raha Hassan  Louis A. Schmidt 《Child development》2021,92(5):2006-2019

The authors examined how children’s frontal electroencephalogram (EEG) theta/beta ratio—an index of neurocognitive control—changed from baseline to a social stressor, and whether these EEG changes moderated the relation between temperament and anxiety. Children (N = 152; M_age = 7.82 years, 52% male, 81% White) had their EEG recorded during a baseline and speech anticipation condition. Children’s frontal theta/beta ratio decreased from baseline to speech anticipation, and this baseline-to-task change moderated the relation between temperamental shyness and social anxiety. Temperamental shyness was related to higher state and trait social anxiety only among children with large baseline-to-task decreases in theta/beta ratio. Findings are consistent with theoretical models hypothesizing that temperamentally shy children with heightened neurocognitive control may be at greater risk for anxiety.  相似文献   

Physicochemical characteristics of various milk samples available in Pakistan     

Imran M  Khan H  Hassan SS  Khan R 《Journal of Zhejiang University. Science. B》2008,9(7):546-551

We report physicochemical characteristics of various kinds of liquid milk commercially available in Pakistan in comparison with those of fresh natural milk from animals. Milk samples were collected from local markets at Peshawar, Pakistan,and analyzed for their physical features, including moisture, total solids, specific gravity, conductivity, viscosity and titratable acidity (lactic acid equivalent), and chemical components and macro-minerals, including total protein, casein, lactose, ash and minerals (Na, K and Mg). These items were compared with the physicochemical characteristics of the fresh natural milk samples from buffalo, cow and goat. The results were also compared with reported nutritional quality of milk from various countries and World Health Organization (WHO) standards. We found that all the physical features and chemical components of commercially available milk in Pakistan markets meet WHO's requirements, except for Na, K, Ca and Mg, which are below the standards.  相似文献   

Isolation and distinctiveness in the design of e-learning systems influence user preferences     

Hosam Al-Samarraie  Hassan Selim  Timothy Teo  Fahed Zaqout 《Interactive Learning Environments》2017,25(4):452-466

When faced with excessive detail in an online environment, typical users have difficulty processing all the elements of representation. This in turn creates cognitive overload, which narrows the user's focus to a few select items. In the context of e-learning, we translated this aspect as the learner's demand for a system that facilitates the retrieval of learning content – one in which the representation is easy to read and understand. We hypothesized that the representation of content in an e-learning system's design is an important antecedent for learner preferences. The aspects of isolation and distinctiveness were incorporated into the design of e-learning representation as an attempt to promote student cognition. Following its development, the model was empirically validated by conducting a survey of 300 university students. We found that isolation and distinctiveness in the design elements appeared to facilitate the ability of students to read and remember online learning content. This in turn was found to drive user preferences for using e-learning systems. The findings provide designers with managerial insights for enticing learners to continue using e-learning systems.  相似文献   

An introduction to education research methods: exploring the learning journey of pre-service teachers in a transnational programme     

Sonia White  Erika Hepple  Donna Tangen  Marlana Comelli  Amyzar Alwi  Zaira Abu Hassan Shaari 《Asia-Pacific Journal of Teacher Education》2016,44(1):35-48

Internationally there is interest in developing the research skills of pre-service teachers as a means of ongoing professional renewal with a distinct need for systematic and longitudinal investigation of student learning. The current study takes a unique perspective by exploring the research learning journey of pre-service teachers participating in a transnational degree programme. Using a case-study design that includes both a self-reported and direct measure of research knowledge, the results indicate a progression in learning, as well as evidence that this research knowledge is continued or maintained when the pre-service teachers return to their home university. The findings of this study have implications for both pre-service teacher research training and transnational programmes.  相似文献   

TS fuzzy robust L1 control for nonlinear systems with persistent bounded disturbances     

Navid Vafamand  Mohammad Hassan Asemani  Alireza Khayatian 《Journal of The Franklin Institute》2017,354(14):5854-5876

In this paper, a novel technique for Takagi–Sugeno (TS) model-based robust L₁ controller design of nonlinear systems is proposed. Two synthesis methods based on quadratic and non-quadratic Lyapunov functions are considered. To design the robust stabilizing controller, a new approach for deriving sufficient conditions associated with the L₁ performance criterion in terms of strict linear matrix inequality is proposed. This novel technique results in less pre-chosen scalar design variables and calculation burden. Furthermore, deriving the controller synthesis conditions via a non-quadratic Lyapunov function (NQLF) relaxes the obtained conditions. Therefore, the proposed approaches not only efficiently minimize the effect of persistent bounded disturbance, but also are applicable for wider classes of TS systems. Furthermore, some new lemmas are proposed to facilitate strict LMI formulation and to provide more degrees of freedom. Finally, several numerical and practical examples are presented to show the merits of this paper.  相似文献   

A working memory model applied to mathematical word problem solving   总被引：1，自引：0，他引：1  

Hassan Alamolhodaei 《Asia Pacific Education Review》2009,10(2):183-192

The main objective of this study is (a) to explore the relationship among cognitive style (field dependence/independence), working memory, and mathematics anxiety and (b) to examine their effects on students’ mathematics problem solving. A sample of 161 school girls (13–14 years old) were tested on (1) the Witkin’s cognitive style (Group Embedded Figure Test) and (2) Digit Span Backwards Test, with two mathematics exams. Results obtained indicate that the effect of field dependency, working memory, and mathematics anxiety on students' mathematical word problem solving was significant. Moreover, the correlation among working memory capacity, cognitive style, and students’ mathematics anxiety was significant. Overall, these findings could help to provide some practical implications for adapting problem solving skills and effective teaching/learning.  相似文献   

An examination of Hispanic college enrollment and graduation: Has the Texas Closing the Gaps plan been successful?     

Hassan Tajalli  Marta Ortiz 《Journal of Latinos & Education》2018,17(4):330-343

The purpose of this study is to assess the effectiveness of the Texas “Closing the Gaps by 2015” plan to increase Hispanic enrollment into and graduation from institutions of higher education. This study uses Interrupted Time Series with Comparison Group to analyze 26 years of student cohorts in Texas universities. Controlling for historical enrollment and graduation growth as well as population growth, the results show that Hispanic college enrollment significantly increased as a result of the plan, but graduation did not. Several recommendations are offered for those states that wish to emulate Texas policies of increasing college enrollment and graduation of Hispanics.  相似文献   

Flatness-based adaptive fuzzy output tracking excitation control for power system generators     

Hassan A. Yousef  Mohamed Hamdy  Muhammad Shafiq 《Journal of The Franklin Institute》2013

In this paper, a novel approach for the design of an indirect adaptive fuzzy output tracking excitation control of power system generators is proposed. The method is developed based on the concept of differentially flat systems through which the nonlinear system can be written in canonical form. The flatness-based adaptive fuzzy control methodology is used to design the excitation control signal of a single machine power system in order to track a reference trajectory for the generator angle. The considered power system can be written in the canonical form and the resulting excitation control signal is shown to be nonlinear. In case of unknown power system parameters due to abnormalities, the nonlinear functions appearing in the control signal are approximated using adaptive fuzzy systems. Simulation results show that the proposed controller can enhance the transient stability of the power system under a three-phase to ground fault occurring near the generator terminals.  相似文献
