seed hardiness in annual medics plays an important role in soil seed bank reserve to ensure ley farming system sustainability. to study the level of seed hardiness in annual medic (medicago scuttelata var.rabinson) at different fertilizing treatments and growing conditions (irrigated and dry farming system), an experiment was conducted at two research stations (sararod, research institute and s...
Simulation of dam-break flood and risk assessment: a case study of Chengbi River Dam in Baise, China
Abstract When a reservoir is damaged, it will bring destruction to people's lives and the regional economy. Flood simulation risk assessment are two effective ways mitigate flood risk. assessed by using hazard vulnerability indices. However, one of key concerns how quantify hazards vulnerabilities more rationally. To this end, study introduces new quantitative method for assessment. Three schem...
We propose an efficient method to break H-MAC, by using a generalized birthday attack to recover the equivalent key, under the assumption that the underlying hash function is secure (collision resistance).
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
Molten aluminum droplets are generated from capillary stream break-up and are injected into an inert environment. The intrinsic fidelity of droplet formation from capillary stream break-up provides the allure for use in advanced manufacturing applications such as net-form manufacturing and electronics packaging for the two following reasons: first, because the droplets are generated with extrem...
We investigate the power and size performance of unit root tests when the true data generating process undergoes Markov regime-switching. All tests, including those robust to a single break in trend growth rate, have very low power against a process with a Markov-switching trend growth rate as in Lam (1990). However, for the case of business cycle non-linearities, unit root tests are very power...
In this paper, a synthesis of the recently advanced Lagrange multiplier (LM)-based tests for the null of no cointegration which account for different patterns of breaks in the cointegrating relationship is provided. The limiting distributions of the test statistics are not only invariant to an intercept break and a break in the cointegrating vector, but are also invariant to a trend break in a ...
purpose: to evaluate changes in tear condition following unilateral ptosis surgery. methods: in this case series all patients with unilateral ptosis who underwent ptosis surgery over a two-year period were studied. the patients did not have history of previous eye surgery or other eye problems. eyelid and lacrimal evaluation included schirmer’s test with and without anesthesia and tear break up...
Although the musculoskeletal injuries associated with break-dancing which is gaining more popularity among adolescent and young people has been reported, the report regarding a peripheral nerve injury associated with breakdance is scarce. We report a rare case of a young amateur break-dancer, 'b-boy' who suffered from a painful paresthesia in his left hand, later diagnosed as type III Guyon's c...
