Abstract:

Attaining maximum sustained yield (MSY) is a central goal in U.S. fisheries management. To attain MSY, fishing mortality is maintained at FMSY and biomass at BMSY. Replacing FMSY and BMSY by “proxies” for FMSY and BMSY is commonplace. However, these proxies are not equivalent to FMSY and BMSY. The lack of equivalency is an important issue with regard to whether MSY is attained or whether biomass production is wasted. In this paper we study the magnitude of the equivalency. We compare FMSY/BMSY (calculated using the ASPIC toolbox) with the proxy estimates, F40%/B40%, published in GARM III. Our

Abstract:

The concept of sustained yield is examined with particular reference to the sustained yield concept as it is required to be applied by Alberta law and through the requirements of the regulations, timber quota certificates and forest management agreements. The adequacy of the sustained yield vision in Alberta is discussed. Actual forest management practices are examined in the light of the Alberta requirements. Some shortcomings are noted, and a number of serious problems are described. However, the author concludes that a dedicated and successful effort is being made, and the most important pr

Abstract:

Sustained yield has been a tenet of faith among foresters since forestry emerged as a profession. The concept developed during feudal times when foresters were primarily gamekeepers for landed aristocracy. When the industrial revolution put new demands on forests for fuelwood, foresters extended their "bag limits" to the trees, based on the perception that unregulated markets would result in forest devastation. Early foresters believed that governments must own or regulate forests to perpetuate timber resources. This belief is the basis for extensive public forests today in Canada, the United

Abstract:

There are gaps between expectations and realities with respect to sustainability in the forests of Canada. While all forestry agencies have a policy of sustained yield, there is public confusion over what is being sustained, on what area, and for what period of time. Given the scale of forestry in Canada, and the fact of predominantly public ownership of the forest, this is a dangerous situation. At present, the claims of professional managers that sustainability is a reality in the forests do not enjoy public acceptance.There is a tendency, both in the profession and among the public, to spea

Abstract The impact of block size and exclusion period on sustained yield predictions is examined for 27 hypothetical forests; forests are delineated by species, site and rotation age. Long-range harvest schedules are developed for the forests using (1) aspatial, strata-based formulations solved with linear programming, and (2) spatial, block scheduling formulations solved with Monte Carlo Integer Programming. The sustained yields estimated by the spatial formulations are in all cases lower (range: 2% to 29%) than those estimated by the aspatial formulations. The magnitude of the reduction in

Sustainable forest management may be considered an evolutionary step beyond sustained yield management. Although objectives related to sustainable forest management are common in Canada, policy means of achieving these objectives are rarely spelled out. Currently, forest tenure policies are dominated by concepts associated with sustained yield that may preclude the realization of sustainable forest management objectives. This paper identifies how tenure policies based on sustained yield concepts of allowable annual cuts could change in order to address a more holistic view of forests associate

Sustained yield is the amount or number of a resource that can be harvested without sending the resource into a decline.

Abstract:

Sweden is a small but quite active forest country. Occupying about 0.6% of the world forest land area it holds about 15% of the international wood products market. The standing volume of forests has increased continuously since about the year of 1900. Many factors have contributed to this positive development. One is Sweden's conversion from a poor underdeveloped agrarian country to a modern industrial one. This meant a tremendous increase in agricultural efficiency and thus an important release of land which could be shifted from agriculture to forestry. But another reason for increased fores

Methods for estimating fish production in aquatic ecosystems range from simple empirically derived estimators, such as morphoedaphic indices, to complex ecosystem simulation models. As first-order estimators, the former are attractive to managers because they are simple and relatively inexpensive to apply and interpret. Application of the latter group has been limited because many of the data inputs are difficult and expensive to obtain. Between these extremes are several models, such as the biomass–size spectrum model, that provide useful information for moderate expenditures of time and effo

Partitioning the forest into sustained yield units is a complex task that involves assessing timber supply, allocation of cutting rights, and social, economic, and environmental impacts.

In this paper we use a spatial forest planning model to examine economic and environmental implications of varying the sustained yield unit size.

With the management approach outlined here, average annual volume growth may approach that of shorter-rotation culture, but in logs of a size and quality normally found only in older stands, and with minimal impact on high-risk watersheds or old-growth habitat.

This paper considers the question of whether sustainable forest management (SFM) should continue to incorporate sustained yield (SY) requirements, as it currently does in many jurisdictions. We evaluate the extent to which SY and SFM are consistent with notions of weak and (or) strong sustainability. Strong sustainability implies placing constraints on the reduction of stocks of natural capital to prevent irreversibility and (or) protect flows of services that have public good characteristics. In contrast, weak sustainability may allow market forces to draw down stocks of natural capital so lo

This metaphor clarifies the distinction between economic efficiency and forest policy. In particular, it indicates the ultimate inevitability of the financial rotation age while demonstrating that the financial rotation age implicitly rejects the notion of sustained yield.

Abstract:

Photosynthesis is the basis of primary productivity on the planet. Crop breeding has sustained steady improvements in yield to keep pace with population growth increases. Yet these advances have not resulted from improving the photosynthetic processper sebut rather of altering the way carbon is partitioned within the plant. Mounting evidence suggests that the rate at which crop yields can be boosted by traditional plant breeding approaches is wavering, and they may reach a “yield ceiling” in the foreseeable future. Further increases in yield will likely depend on the targeted manipulation of p

Abstract:

This research study aims to develop and characterize of polymeric sustained release microspheres of Nateglinide (NTG), anti-diabetic drug known for its shorter half-life, which leads to poor bioavailability and frequent dosing. NTG polymeric microsphere developed by Emulsion-Solvent Diffusion-Evaporation method. Ethyl cellulose was used as rate retarding material. The polymeric microsphere were characterised for % yield, encapsulation efficiency, drug release, FTIR, and SEM. The developed NTG polymeric microspheres were smooth and spherical with porous nature and showed entrapment efficiency i

Abstract:

The current research focused on developing and characterizing sustained-releasemicrospheres of miconazole nitrate (MCN) with different polymers to optimize drugentrapment efficiency and manage drug release. Microspheres were produced with anoptimized method and examined for particle size, surface topography, yield percentage,drug content, entrapment efficiency, and in vitro drug release kinetic. Optical microscopyand scanning electron microscopy (SEM) validated the spherical microspheres with a sizeof 140–210 µm. The entrapment efficiency of the drug ranged from 72.06 ± 6.09 to 89.45± 5.18 %,

Abstract:

Mango is one of the most cultivated tropical fruits worldwide and one of few drought-tolerant plants. Thus, in this study the effect of a sustained deficit irrigation (SDI) strategy on mango yield and quality was assessed with the aim of reducing irrigation water in mango crop. A randomized block design with four treatments was developed: (i) full irrigation (FI), assuring the crop’s water needs, and three levels of SDI receiving 75%, 50%, and 33% of irrigation water (SDI75, SDI50, and SDI33).

Abstract:

The aim of this study was to formulate and characterize oxazepam-loaded microspheres for sustained drug release to enhance its therapeutic efficacy in the treatment of anxiety and insomnia. Various formulations of microspheres were prepared using HPMC, ethyl cellulose (EC), and guar gum as polymers, and their physical properties, such as yield, drug entrapment efficiency, buoyancy, and floating lag time, were evaluated. The optimized formulation (F4) exhibited a high percentage yield (73.32±0.22%) and drug entrapment efficiency (72.23±0.32%). Furthermore, F4 showed the shortest f
