Alternative solutions

Natural products have been gaining popularity in recent years as a safe skin-safe alternative solution to synthetic products on the market. In particular, natural ingredients have been found to have skinwhitening properties by inhibiting melanin production and reducing hyperpigmentation. This review provides the analysis of some mechanisms and effectiveness of natural products in achieving even skin tone and reducing the appearance of dark spots.

The study was carried out to observe the effect of post harvest application of sucrose on extension of vase life of cut rose cv. Tajmahal. The data was recorded on the physical and physiological parameters on every alternate day. The flowers were held in different concentrations of sucrose solutions with flowers harvested at two stages i.e. tight bud stage and first petal unfurl stage.

Software-defined networking (SDN) represents a new structure of computer network that simplifies and improves network management by splitting the control plane and data plane. Since SDN is regarded as a new research issue, the application of SDN in practice faces some barriers. Most network devices such as routers and switches that implement SDN functionalities are expensive. An alternative solution in SDN research and experiments is to use network emulators. By using Mininet, an open source network emulator, this study simulates SDN implementations in different environments.

As businesses become increasingly dependent on the network, the availability of the network infrastructure becomes a critical business concern. • Redundancy is the solution for achieving the necessary availability. • Layer 2 redundancy improves the availability of the network by implementing alternate network paths by adding equipment and cabling. • Having multiple paths for data to traverse the network allows for a single path to be disrupted without impacting the connectivity of devices on the network...

The major components of neuritic plaques found in Alzheimer disease (AD) are peptides known as amyloid b-peptides (Ab),which derive from the proteolitic cleavage of theamyloidprecursorproteins.InvitroAbmayundergoa conformational transition from a soluble form to aggrega-ted,fibrillary b-sheet structures,which seem to be neuro-toxic. Alternatively,it has been suggested that ana-helical form can be involved in a process of membrane poration, which would then trigger cellular death.

The solutionmolecular andelectronic structuresof theactive site in the extremelyO2-avidhemoglobin fromthe trematode Paramphistomum epiclitumhave been investigated by 1 H NMR on the cyanomet form in order to elucidate the distal hydrogen-bonding to a ligated H-bond acceptor ligand. Comparison of the strengths of dipolar interactions in solution with the alternate crystal structures of methemo-globin establish that the solution structure of wild-type Hb more closely resembles the crystal structure of the recom-binant wild-type than the true wild-type met-hemoglobin....

FIRST- AND SECOND-ORDER DYNAMIC EQUATIONS WITH IMPULSE F. M. ATICI AND D. C. BILES Received 3 December 2004 and in revised form 11 February 2005 We present existence results for discontinuous first- and continuous second-order dynamic equations on a time scale subject to fixed-time impulses and nonlinear boundary conditions. 1. Introduction We first briefly survey the recent results for existence of solutions to first-order problems with fixed-time impulses. Periodic boundary conditions using upper and lower solutions were considered in [19], using degree theory.
