Evaluation and Determination of the Appropriate Method for Assessing Optimum Utilisation Rate of \u3cem\u3eEurotia Ceratoides\u3c/em\u3e in Upland Grasslands of Iran
Determination of optimum utilisation rate for different range species is an important factor in assessing range grazing capacity. The vast rangelands in Iran with diverse vegetation types require an accurate, economic and quick method to determine the optimum utilisation rate for different range species. This experiment was conducted to determine the most appropriate method to determine the optimum utilisation rate for Eurotia ceratoides, which is one of the important grass species in upland grasslands in Iran
Effects of Soil Compaction by Animal Trampling on Growth of \u3cem\u3eAgropyron Repens\u3c/em\u3e
Animal trampling is the most important factor that increases soil compaction beyond the soil elastic property in rangelands under heavy grazing intensities (Lull, 1959). The complicated ecological interactions in a rangeland ecosystem make it difficult to predict the impact of trampling under different conditions. However, soil properties and vegetation composition are sensitive to different grazing management practices. This research, which was carried out in simulated conditions, sought to establish the contribution of soil compaction resulting from animal trampling over a long period to the decline in rangeland condition
Multiscale expansion of the lattice potential KdV equation on functions of infinite slow-varyness order
We present a discrete multiscale expansion of the lattice potential
Korteweg-de Vries (lpKdV) equation on functions of infinite order of
slow-varyness. To do so we introduce a formal expansion of the shift operator
on many lattices holding at all orders. The lowest secularity condition from
the expansion of the lpKdV equation gives a nonlinear lattice equation,
depending on shifts of all orders, of the form of the nonlinear Schr\"odinger
(NLS) equationComment: 9 pages, submitted to Journ. Phys.
A Sequential Mixed Method Study of Employee Job Satisfaction in Upscale Restaurants, Malaysia
The study determines the main factors affecting job satisfaction in upscale restaurants and their degree of comparative influence. The research initially involves qualitative data analysis of 20 interviews with restaurant employees representing five upscale restaurants in Kuala Lumpur (KL), followed by structural equation modeling of data retrieved from 368 questionnaires from 16 KL restaurants. The impact variance of four main determinants of job satisfaction are revealed, where the âworking environmentâ has the highest impact, followed by âpayment and compensation,â âpromotionâ, and finally, âworkplace fairnessâ. Crucially, âworkplace relationshipsâ have a moderating effect on the relationship between the âwork environmentâ and job satisfaction, implicating industry-applied recommendations to strengthen job satisfaction levels
Brand love impact on the social media and stages of brand loyalty
The primary objective of the current research is to propose and investigate a conceptual model which integrates social media activities and brand love as antecedents and brand loyalty phases as an outcome of brand love. The proposed model is analysed with a sample of 240 fast fashionâs consumers by using a self -structured questionnaire survey technique. PLS -SEM applied for statistical analysis to evaluate the hypnotized linkage between the variables. The results show that social internet marketing has a tremendous impact on brand love in the fast fashion profession. Furthermore, the finding shows that social media, has an indirect constructive effect on the various phases of brand loyalty through brand love. The current research supports the crucial role of social media in marketing and advertising which will assist internet marketers to fully realize brand love and loyalty behavior. The consequence of this particular study might assist marketers to develop the successful communication approach through social networking activities to shape good attitudes and advance brand loyalty, particularly in fast fashion profession
Examples of signature (2,2) manifolds with commuting curvature operators
We exhibit Walker manifolds of signature (2,2) with various commutativity
properties for the Ricci operator, the skew-symmetric curvature operator, and
the Jacobi operator. If the Walker metric is a Riemannian extension of an
underlying affine structure A, these properties are related to the Ricci tensor
of A
Curvature operators and scalar curvature invariants
We continue the study of the question of when a pseudo-Riemannain manifold
can be locally characterised by its scalar polynomial curvature invariants
(constructed from the Riemann tensor and its covariant derivatives). We make
further use of alignment theory and the bivector form of the Weyl operator in
higher dimensions, and introduce the important notions of diagonalisability and
(complex) analytic metric extension. We show that if there exists an analytic
metric extension of an arbitrary dimensional space of any signature to a
Riemannian space (of Euclidean signature), then that space is characterised by
its scalar curvature invariants. In particular, we discuss the Lorentzian case
and the neutral signature case in four dimensions in more detail.Comment: 26 pages, 2 figure
