Theoretical Framework for Spatial Planning and Forest Management in Indonesia: Securing the Basic Rights for Adat People

Limited transparency, accountability, and participation in policy formulation as well as implementation mainly based on economic considerations, all lead to failure to attain sustainable forest management (SFM). Along with the reluctance of policy makers and lacking stakeholder capacity, less accurate data bases has also indicated a constraint in the development of appropriate action. The issues have been more complicated where they were correlated with economic imperatives, vested interest, ownership issues and the basic rights of indigenous communities living inside or adjacent the forest. Forest destruction will be no end without securing customary land and territorial rights. To cope with these issues, the concept of fair governance has been promoted as an alternative to the traditional pattern of administration. In this paper, we propose a theoretical framework for policy development in order to attain SFM while respecting the rights of the adat people. We show that adaptive governance, adaptive management, and participatory learning are strategic approaches in governance reform to achieve sustainable forest management securing the customary rights and traditional land use of forest dependent people

On-chip architecture for self-homodyned nonclassical light

In the last decade, there has been remarkable progress on the practical integration of on-chip quantum photonic devices, yet quantum-state generators remain an outstanding challenge. Simultaneously, the quantum-dot photonic-crystal-resonator platform has demonstrated a versatility for creating nonclassical light with tunable quantum statistics thanks to a newly discovered self-homodyning interferometric effect that preferentially selects the quantum light over the classical light when using an optimally tuned Fano resonance. In this work, we propose a general structure for the cavity quantum electrodynamical generation of quantum states from a waveguide-integrated version of the quantum-dot photonic-crystal-resonator platform, which is specifically tailored for preferential quantum-state transmission. We support our results with rigorous finite-difference time-domain and quantum-optical simulations and show how our proposed device can serve as a robust generator of highly pure single- and even multiphoton states

Treatment with a Urokinase Receptor-derived Cyclized Peptide Improves Experimental Colitis by Preventing Monocyte Recruitment and Macrophage Polarization

Leukocyte migration across the blood barrier and into tissues represents a key process in the pathogenesis of inflammatory bowel diseases. The urokinase receptor (urokinase-type plasminogen activator receptor) is a master regulator of leukocyte recruitment. We recently found that cyclization of the urokinase-type plasminogen activator receptor-derived peptide Ser-Arg-Ser-Arg-Tyr [SRSRY] inhibits transendothelial migration of monocytes. Now, we have explored the effects of [SRSRY] administration during experimental colitis

Multiphoton radiative recombination of electron assisted by laser field

In the presence of an intensive laser field the radiative recombination of the continuum electron into an atomic bound state generally is accompanied by absorption or emission of several laser quanta. The spectrum of emitted photons represents an equidistant pattern with the spacing equal to the laser frequency. The distribution of intensities in this spectrum is studied employing the Keldysh-type approximation, i.e. neglecting interaction of the impact electron with the atomic core in the initial continuum state. Within the adiabatic approximation the scale of emitted photon frequencies is subdivided into classically allowed and classically forbidden domains. The highest intensities correspond to emission frequencies close to the edges of classically allowed domain. The total cross section of electron recombination summed over all emitted photon channels exhibits negligible dependence on the laser field intensity.Comment: 14 pages, 5 figures (Figs.2-5 have "a" and "b" parts), Phys.Rev.A accepted for publication.

Fingerling Production of Orange-Spotted Grouper on Abu Al Abayad Island, United Arab Emirates

The orange-spotted grouper Epinephelus coioides, locally known as hamour, is the food fish in greatest demand and correspondingly fetches the highest price in the local market. However, there has been a significant decline in natural stocks from severe over-exploitation in UAE waters over the last few years, as indicated by decreased landings. The high market demand and reduced natural supplies of the orange-spotted grouper make this species the top potential candidate for aquaculture in UAE

Tuning the photon statistics of a strongly coupled nanophotonic system

We investigate the dynamics of single- and multiphoton emission from detuned strongly coupled systems based on the quantum-dot–photonic-crystal resonator platform. Transmitting light through such systems can generate a range of nonclassical states of light with tunable photon counting statistics due to the nonlinear ladder of hybridized light-matter states. By controlling the detuning between emitter and resonator, the transmission can be tuned to strongly enhance either single- or two-photon emission processes. Despite the strongly dissipative nature of these systems, we find that by utilizing a self-homodyne interference technique combined with frequency filtering we are able to find a strong two-photon component of the emission in the multiphoton regime. In order to explain our correlation measurements, we propose rate equation models that capture the dominant processes of emission in both the single- and multiphoton regimes. These models are then supported by quantum-optical simulations that fully capture the frequency filtering of emission from our solid-state system

Induced spawning and larviculture of grey mullet, Mugil cephalus (Linnaeus 1758) in the Emirate of Abu Dhabi

Grey mullet, Mugil cephalus, is one of the most widely distributed food fi shes in the world (McDonough et al., 2003). In the United Arab Emirates (UAE), the fi sh, locally known as Biah or Wagena, is considered as one of the most highly demanded fi sh. However, it was recently recognized that the landings of this species have drastically decreased and its presence in the local fi sh markets became rare (MAF, 2003). In captivity, grey mullets do not spawn spontaneously and that could be achieved successfully by hormone administration (Lee and Tamaru, 1988, El-Gharabawy and Assem, 2006). This has lead to increasing interest by the Aquaculture Center, Abu Al Abyad Island (ACAAB), Emirate of Abu Dhabi, UAE to propagate the fi sh. The ACAAB is situated in Abu Al Abyad Island which is the major island of the Emirate of Abu Dhabi covering an area of 490 km2. The island is characterised by its harsh environmental conditions where water temperature and salinity during summer time reach as high as 36 ºC and 58 ppt, respectively (Al Abdessalaam and Yousif, 2002).The results of the fi rst induced spawning and larviculture trials of this species under the environmental conditions of Abu Al Abyad Island (50 -55 ppt) are presented in this article

Spawning and larval rearing of goldlined seabream, Rhabdosargus sarba on Abu Al Abyad Island, United Arab Emirates

The goldlined seabream, Rhabdosargus sarba, a carnivorous and euryhaline sparid, is widely distributed in subtropical and tropical waters throughout the Indo-West Pacific including the Red Sea, East Africa, Madagascar, Australia, China and Japan (Leu 1994, Mihelakakis and Kitajima 1995, Radebe et al. 2002). It is a shallow-water species that is usually found around reefs with sandy bottoms. In some regions of the world, such as the waters of Hong Kong and South Africa, the fish is a protandrous hermaphrodite, but in other environments, including Western Australia, it is described as a rudimentary hermaphrodite (Hesp et al. 2004)

Spawning and larviculture trials of cobia, Rachycentron canadum (Linnaeus, 1766) in the United Arab Emirates

Cobia Rachycentron canadum, the sole representative of the family Rachycentridae, is a migratory pelagic species that occurs in tropical and subtropical seas except for the eastern Pacific (Arnold et al. 2002). It is a gonochoristic species that has demonstrated the capacity for high fecundity and ease of induced and natural spawning in captivity (Holt et al. 2007, Benetti et al. 2008a). They are multiple batch spawners with a protracted spawning period (Faulk and Halt 2003, Benetti et al. 2008b). The information available on the timing of gonadal maturation in different parts of the world indicates that cobia spawn from April through September with the peak in spring and early summer (Kilduff et al. 2002, Faulk and Halt 2003)
