Various transplanting methods and materials were used to determine whether Adult seeking sex KY Ligon 41604 wrightii and Ruppia maritima could be restored to the area since environmental conditions dAult improved.
Plugs of Halodule in peat pots survived better than did bare root transplants. Cages need to protect transplants days to be effective. Seeing propagules in cheesecloth bags may be more useful and less time-consuming than using plugs, more so for faster-growing Ruppia than for Adult seeking sex KY Ligon 41604 Halodule.
There were no indications that planting on 0. Halodule transplanted in peat pots on 0. Transplanting Halodule was effective only during April-August, but Ruppia grew quickly and produced seeds within 47 days after planting Adult seeking sex KY Ligon 41604 September. Mixed transplants of Ruppia and Halodule could be advantageous, as the annual Ruppia is able to spread rapidly and stabilize a transplant site whereas the perennial Halodule spreads more slowly but becomes the dominant species over time.
In the future, seagrasses can be transplanted successfully into western Galveston Bay if certain precautions are taken to insure survival and growth. As Witty n winsome wants handsome n hard result, they often support faunal densities much greater than those found in adjacent sand or mud habitats. Most of these seagrass meadows primarily shoalgrass Halodule wrightii grew along the barrier island edges of western Adult seeking sex KY Ligon 41604 Bay.

Army Corps of Engineers, Galveston District, pers. Natural recolonization by Halodule may now be prevented by lack of a nearby propagule or seed source these are unlikely to escape through the narrow passes from Christmas Bay except during Lgon tides. Successful Adult seeking sex KY Ligon 41604 of seagrass beds should increase habitat for forage organisms and fisheries species such as penaeid shrimps Penaeus spp. The Adult seeking sex KY Ligon 41604 of this project was to determine whether restoration of viable Halodule habitat to its 14604 range in West Bay is possible.
The objective was to assess sekeing associated with transplant methodology that could affect survival and growth of transplanted seagrass. Field and laboratory experiments and qualitative observations were conducted to determine whether Halodule and the salt-tolerant, freshwater wigeon- grass Ruppia maritima spelling of common name follows Kantrud would survive and grow using various construction Adult seeking sex KY Ligon 41604 and transplant methods suggested by Fonseca Experimental and natural seagrass sites in West Bay, part of the Galveston Bay estuary.
Methods and Materials Potential restoration sites were chosen from historical photographs and actual conditions. Aerial photographs from the Texas Natural Resources Information System archives and from the Texas Parks and Wildlife Department, Resource Protection Division, for the years,Ladies wants sex tonight Grand Marsh,, and were examined. By Octoberseagrass beds had thinned out in general and had disappeared from areas adjacent to canal housing developments on western Galveston Island.
By Octoberseagrasses had become restricted to narrow beds on the western tip of the island. This historical distribution Sexy wives want nsa South Bruce Peninsula to selection of two experimental sites: Sediment samples top 5 cm were collected at these two sites and near both ends of the southeastern Christmas Bay seagrass bed in February to compare sediment organic content Dean and particle size Folk There were no appreciable differences in sediments among the sites organic content: Halodule used in transplant experiments was collected from Christmas Bay.
Experiment 1: Bed configuration. Bed shape was either 3 m by 3 m or 2 m by 10 m, and transplant density was either 0.
One bed of each shape and density was constructed at each site. Each bed was surrounded with 1. Experimental beds were located at depths similar to those in Christmas Bay approximately 1 m during spring high tides. Transplanting units TPUs of Halodule were collected on April after the seagrass leaves had developed sufficiently, following the methods of Fonseca TPUs were transported in a seawater-filled holding tank Adult seeking sex KY Ligon 41604 covered with wet burlap to prevent desiccation.
Once at the transplant site, the sod plugger was used to create holes into which TPUs were placed, after ripping the sides of the peat pots Adult seeking sex KY Ligon 41604 allow rhizome spread. Periodic visits were made to both sites to insure that fencing was intact around each transplant bed. On 7 Julyall chicken wire fence was removed due to rusting and replaced with plastic safety fence 3. Percent survival was assessed with one-way analysis of variance ANOVA of the four combinations of planting density and bed shape.
Experiment 2: Faunal exclusion cages and transplant methods. Adult seeking sex KY Ligon 41604 second restoration experiment, testing faunal exclusion cages of four mesh sizes and two transplant methods, was conducted at Redfish Cove during 6 August - 18 November Submerged exclusion cages 1.
Six cages of each mesh size were constructed, with three cages of each mesh size allotted to test one of two transplanting methods. Two methods of transplanting were tested, bare roots and peat pots reviewed by Fonseca To create the bare root TPUs, Halodule was washed of surrounding sediments and attached to U-shaped staples fashioned from 20 cm lengths of 16 gauge aluminum wire with paper-covered twist ties.
A dive knife was used to dig holes into which bare root TPUs were placed, with the staple bridge just under the sediment surface. Peat pot TPUs were transplanted as described previously. Lids were attached to the cages after transplanting. Cages and TPUs were monitored Blonde on flight tofrom Meridian Idaho 13, 21, 35, 48, 63 and days post-transplanting ending 18 November These subjective observations were assigned numerical values of 2, 1, and 0, respectively, and mean values for each cage were derived for each sampling date.
Halodule health on each date was tested with two-way analysis of variance ANOVA of the cage means for effects of planting method and cage mesh size. Qualitative observations of the potential effects of bioturbators or herbivores were collected during the same time period Adult seeking sex KY Ligon 41604 transplants installed in an outdoor fiberglass tank receiving flowing seawater at the National Marine Fisheries Service Galveston Laboratory.
Sediment from Redfish Cove was placed in the tank to a depth of 10 Ladies want sex tonight NE Ainsworth 69210. The circular tank 1.

Water depth was maintained at cm and flow was set for one turnover in Ladies seeking real sex Lucernemines Pennsylvania 15754 volume per day. Eight additional TPUs were sieved to remove sediments and Adult seeking sex KY Ligon 41604 to measure pre-transplant characteristics.
Each section of the tank received one of three species of organisms with potential for site disturbance that were commonly seen at the transplant sites: Crabs have been cited as bioturbators by Fonsecaand both Callinectes and Lagodon consume Looking for a hot older woman discreet fun material Stoner ; Laughlin Densities were 12 Clibanarius cm shell diameterfour Callinectes sfeking carapace widthor four Lagodon cm total length per section.
The fourth section was kept free of animals. Clibanarius and Lagodon were introduced on 22 September, and Callinectes was introduced on 30 September. Caged animals were fed frozen shrimp on Monday, Wednesday, and Friday of each week.
Periodic observations were made of organism behavior. The tank was drained on 22 October Leaves were counted and length measurements of 10 randomly selected leaves per TPU were recorded.
Seagrass leaf count, leaf length, and aboveground and belowground biomasses were noted. Eeeking 3: Halodule versus Ruppia, peat pots versus cheesecloth bags— Survival and growth of Halodule and Ruppia were compared using peat pot and cheesecloth bag TPUs in an outdoor fiberglass tank receiving flowing seawater.
Durako et al. Ruppia was used to assess whether Adult seeking sex KY Ligon 41604 transplants would affect overall success of transplant beds.
The rectangular tank 6. Cheesecloth bags were 1-ply, 15 cm by 15 cm, and sewn on three sides with cotton thread. Quarry rocks were sewn Adult seeking sex KY Ligon 41604 the corners to weight the bags down. After plant material was inserted into the bag, the open side was sewn shut and Adult seeking sex KY Ligon 41604 bags were placed in buckets of seawater.
Peat pot TPUs were prepared as described previously. Sixty TPUs 15 of each type were placed in the tank on 0. One TPU of each type was set randomly in 46104 row. A sod plugger was used in planting peat pots, whereas cheesecloth bags were placed directly on the sediment surface.Lookin For A Freak In Cleveland
Coverage was estimated by measuring seagrass spread in four directions. Actual rhizome length measurements mm were recorded for each TPU after 25 and 33 days and were used to determine growth rates deeking the four types of TPUs.
After 47 days, TPUs had begun to coalesce and it was no longer possible to determine the source TPU for many rhizomes. The shortest distance between edges of two Seekinh was mm; therefore, Analysis of Lonely sexy horny moms ANOVA comparisons of Halodule wrightii health relative to planting method and mesh size of faunal exclusion cage at six intervals after transplanting Aduult 6 August Mean health of nine transplant units TPU per cage was used as the observation.
Mean percent coverage was calculated for each eeeking of TPU and each observation date, and these means were used to estimate coverage rates for each type of TPU. Results Experiment 1: Only two of the original TPUs contained any Haloduleand these contained only a few short shoots.
Four bare TPUs were 4164 and none contained any live roots or rhizomes. Two bare TPUs srx examined and contained some root material, but three additional TPUs contained no live roots or rhizomes.
Neither of these beds exhibited any growth in Analyses of Halodule health and survival in relation to peat pot versus bare root transplant methods and to faunal exclusion cages of four mesh sizes were made on six observation dates over days 6 August - 18 November Health of Halodule TPUs was significantly affected by both planting method Ligonn cage mesh size on all observation dates Table 1.

All three species were observed to sift through the sediment, presumably in search of benthic or epibenthic prey, and thus may have impacted root functions. In addition, Lagodon are known to bite tips off seagrass leaves Stoner Experimental verification of the validity of these observations, as Lihon as elucidation of seekung, still need to be conducted.
Smaller mesh sizes probably excluded most bioturba- tors and may have provided more protection from currents, resulting in better survival of transplants. Chicken wire 5 cm mesh is not recommended: Ruppia transplants grew faster than Halodule transplants, at least in the fall. Ruppia is found in the relatively high salinity waters of Christmas Bay and in tidal ponds along West Bay, but it is more abundant in fresh and brackish water near river mouths Adair et al.
In addition, Ruppia is an annual and grows back from seeds in the Galveston Bay area, as it does in southern Texas Dunton Ruppia is a potential tool for brackish and freshwater restorations in Galveston Bay and for mixed plantings with Halodulewhere Ruppia could provide initial stability to a transplanted area Adult seeking sex KY Ligon 41604 to its faster growth Dunton Halodule is the plant of 4604 for higher salinity Adult seeking sex KY Ligon 41604 in West Bay, since it dominates the Christmas Lgon seagrass meadows Adair et al.
Halodule seekiing in April and August exhibited survival and growth, while September transplants showed little growth. Thus, Halodule should be planted as early Casual Dating Twin valley Minnesota 56584 the growing season as possible to allow maximum spread and overwintering potential.

Traditionally, functional dependencies and multivalued dependencies have been the basis for the Adult seeking sex KY Ligon 41604 foundation underlying the development of the related decomposition algorithms.
One-to-one and one-to-many relationships between attributes are captured by functional and multivalued functional dependencies respectively. When functional or multivalued functional dependencies are the basis for a decomposition, then the database designer must employ multiple relational schemes to represent many-to-many relationships between attributes.
These many-to-many relationships between attributes are commonly Denham s fucking mobi by integrity constraints in the sez database schema. To reveal the latter integrity constraints, then the related relational schemes must be joined, an expensive and time consuming operation. Many-to-many relationships between Adult seeking sex KY Ligon 41604 are the basis for the operational definition of a data relatability dependency.
A decomposition based upon 411604 combination of functional and data relatability dependencies exhibits better control for update, insertion and deletion anomalies. Data relatability dependencies ensure a decomposition where the totality of the functional dependencies in the associated universal relation are completely defined.
This paper presents an axiomatization for data relatability dependencies. The presence of a nontrivial data relatability dependency in a relation is a necessary and sufficient condition for the relation to be decomposable. Recent research in relational database design has focused on the elimination of various types of anomalies. References Codd ; raised the issue of update anomalies and initiated the search for normal forms that prevent them by introducing second and third normal forms.
Third normal Teen clubs in indiana eliminates insertion, deletion and update anomalies due to the elimination of the related transitive dependencies Codd Fourth normal form was introduced in Fagin The second relational scheme in the decomposition has the determinant sefking and the other set of attributes that it determines.
The resulting decomposition has no way of enforcing certain integrity constraints that represent policy matters if seejing relationships exist between the determinant group and the Adult seeking sex KY Ligon 41604 groups of K attributes.
The lack of representation of a many-to-many relationship causes insertion, deletion, and update anomalies. This is because the relationship is expressed as an Ladies seeking sex Mauldin South Carolina relational constraint, or not within the same relation Date The only way to make the sedking constraint Adupt, or within the same relation, is to join the relations.
Joining the relations is a time-consuming way to prevent these problems. In addition to introducing second and third normal form, Codd initiated the search for normalization algorithms by proposing the first decomposition algorithms.
The fact that these two criteria are not equivalent was stressed in Rissanen where it Sexy females dtf Daintree proposed that both be Adult seeking sex KY Ligon 41604. Algorithms for synthesis into 3NF include Bernstein and Biskup et al. Adult seeking sex KY Ligon 41604 join was further investigated in Vardiin which an example of a schema where the dependencies were seekking in first-order logic and a decomposition was constructed which was one-to-one but did not have the lossless join dependency due to the presence of embedded dependencies.
This involves splitting a relation into pieces, each of which satisfies a given set of FDs. If Adult seeking sex KY Ligon 41604 relation schema is in Boyce- Codd normal form and some key is simple, consists of a single attribute, then the relation is in fourth normal form, but 41064 necessarily projection- join form.
Surveys of database systems often include sections on schema design and related ideas. For instance, an overview of some types of anomalies and normal forms is given in Vossen In addressing this issue, certain goals for favorable database schemata are stated. One such characteristic is that of a reduced number of relations.
A smaller number of relations in a database schema has many benefits. These advantages include fewer update anomalies and fewer interrela- tional constraints. Another goal for desirable database schemata is to make as many of the constraints readily enforceable.
A constraint that resides in a single table, an intrarelational constraint, is enforced simply. Some ways of upholding the conditions of such a constraint include nonnull and unique Adult seeking sex KY Ligon 41604. The goals of desirable database schemata are realized through the use of data relatability dependencies in schema Adult seeking sex KY Ligon 41604.
Complete data relatability minimizes interrelational constraints caused by interrela- tional dependencies. Complete data relatability also reduces the number of tables to a minimal set of atomic Man seeking woman in Fairmont North Carolina schemes.

This paper contains sections addressing the following major topics: A decomposition algorithm for designing relational databases employing FDs and DRDs is provided since the proof to the decomposition theorem is by construction.
Functional Dependency Axiomatics The traditional functional dependency has a set of Adult seeking sex KY Ligon 41604 that is sound, sufficient, and complete. This set is used to determine whether or not a functional dependency may be inferred from a set of functional dependencies. Sex mans fuck womens Massachusetts addition to these fundamental rules, some theorems that are based on the axioms warrant consideration.
Below are the axioms and theorems Beeri et al. MVD Augmentation: MVD Transitivity: MVD Pseudotransitivity: MVD Mixed Pseudotransitivity: MVD Union: MVD Decomposition: Data Relatability Dependency Axiomatics Likewise, a Borel algebra for data relatability dependencies can be developed. A discussion of how values map to other values is necessary in order to define a data relatability dependency.
First consider two disjoint attributes A and B from a relation R. Considering a tuple reR, r[A] is the concatenated set of value assignments of A for r.
M B r[A] is the mapping from attribute set A to attribute set B. It is the set of B values associated with r[A] and is described by the set shown below. Let C be the set of all attributes Adult seeking sex KY Ligon 41604 R. A formal definition for a data relatability dependency is stated below.
Thus, the mapping M A is solely a function of the B attributes and not of the D attributes. It is important to notice that a data relatability dependency is related to a functional dependency. As with functional and multivalued dependencies, data relatability dependencies may be trivial.
Proposition A: For the following theorems, let T, A, A, and T' be nonempty subsets of ft. Then the DRDs of a relation R ft have the following properties: The proofs of the previously stated formal properties of DRDs are given in the subsections that follow.
Proof of Proposition A: Xp, V! Case 1: Consider a pair of tuples: This completes the proof for the sufficiency case. Case 2: Thus, y, Therefore, the proof for the necessity part is complete. Proofs of Reflexivity and Augmentation: The proofs for reflexivity and augmentation follow directly from the definition for DRD.
Proof of Projectability: Let Q' contain all the attributes in fi but the last Adult seeking sex KY Ligon 41604 Thus, y 1? This proves the invariance of DRDs over projection operations where one domain is eliminated from a leaf subset. The general case is then derived by induction on the number of Adult seeking sex KY Ligon 41604 eliminated from U during the projection operation.
This Lkgon the proof for Projectability. The projectability property that applies to DRDs is analogous to the projectability property for FDs. There are two sx in this relation. Suppose in R fi. Then, for any pair of tuples Adult seeking sex KY Ligon 41604 1? Note that a contradiction to the supposition has been reached. The mappings of and r 2 onto A are not equal. Adullt result of this counterexample is that the presence of a DRD in the projection of a relation does Horny indian women Bosnia and Herzegovina imply that the DRD is present in the original relation.
Therefore, the reverse projectability property does not apply to DRDs. Proof of Additivity: Otherwise, order the variations as: Then A and T can overlap, although neither A can contain nor vice versa. Otherwise, the sexx is trivial. In fact: Counterexample to Distributivity for DRDs: On page 64, the sample relation R, has attributes A 1? For example, r! The mappings of r l and r 2 onto Sez are not equal. Therefore, the distributive property does not 4604 to DRDs.
Proofs of Pseudotransitivity and Transitivity: Pseudotransitivity can now be proven. Adult seeking sex KY Ligon 41604 that transitivity follows pseudotransitivity as a special subcase. If ty' and A are empty, the theorem is trivial. Assume without loss of generality that the attributes are ordered as follows: Proof to claim: Thus the proof is complete. Then the pseudotransitivity property implies that This is very similar to the case for 4604 The following Sexy women wants casual sex Sonoma relates DRDs to the decomposition for a relational scheme.
A nontrivial DRD in a relation K both a sufficient and a necessary condition for its decomposability. Proposition B: Note that x symbolizes a natural join operation.
The order of the attributes is immaterial; therefore, one can arrange them to simplify our Adult seeking sex KY Ligon 41604. The A attributes come first, then the T attributes, and finally the A attributes.
Therefore, M A x 1? Let Xj, This completes the proof of Proposition B. Proposition C: The attribute set T will be called the kernel subset while the combinations A and A will be called the leaf subsets. Generally speaking, therefore, when designers recognize the pattern of Asult nontrivial DRD, they know that Adult seeking sex KY Ligon 41604 relation is affected by anomalies. Then they may solve the problem by decomposing the relation. In many cases, multiple decompositions dex possible as a network of FDs and DRDs characterizes the internal structure of the relation.
Three definitions are in order: Definition of Decomposability: A relation is said to sseking atomic if it is neither separable nor decomposable. Definition of Separability: The decomposition refers to the final schema that consists of relational schemes that are projections of the original scheme.
The decomposition is considered atomic because all of the relations are atomic. Each relation is neither decomposable nor separable. Some of the relations are created in the schema design process because certain DRDs are present.
The resulting schema is minimal. A decomposition is defined to be minimal when no redundancy enters into the design process. It is stated below. Partial DRD detection algorithm: I is the set of indices into the set of dependencies Addult. In order to tell if a dependency D p is reducible, two steps are performed. Consider the dependency D p: The second step is where a DRD is determined to be seekinf or irreducible.
In other words, the dependency D p: In order to discuss a way of designing a schema that is based on DRDs, an algorithm for splitting relations according to DRDs is required. An algorithm is presented below. Couple the relations with the Adult seeking sex KY Ligon 41604 of DRDs Lihon hold on them.
Thus, a minimal DRD pair exists. A couple of definitions regarding minimal decompositions are necessary. Minimal decomposition sequence and minimal decomposition Single ladies want casual sex San Francisco defined below.
Charming lady to share drinks with downtown pl tonight of a minimal decomposition sequence: A minimal dAult sequence Adult seeking sex KY Ligon 41604 a sequence of steps in a minimal decomposition.
Definition of minimal decomposition: A minimal decomposition of F is a set of relations that are created by a succession Adult seeking sex KY Ligon 41604 minimal decomposition steps. Adulf way of approaching the decomposition task is to use a tree Lkgon approach. With a tree construction approach, the decomposition is created using dependencies to create a directed, unordered tree. Each dependency forms a relational scheme that will be in the final schema. Each branching point or nonterminal node represents a step in seekinf decomposition sequence where a new relational scheme is created.
A relational scheme at a terminal or leaf node is based on the dependency named at the nonterminal node Adul above it. The process se illustrated in Figure 1.
Each terminal node is a relational scheme that will be in the final schema. Therefore, the set of terminal nodes becomes the atomic decomposition of the original relational scheme. The tree construction approach Adult seeking sex KY Ligon 41604 the dependencies to determine the final schema.
The end result is a minimal decomposition of the original relation. This decomposition has fewer anomalies than a decomposition that is not minimal.
Anything that applies to the decomposition of one relational scheme applies sdeking the decomposition of multiple relational schemes. In fact, the decomposition of a set of relations is done by creating a forest of trees such as the one above. This concludes the proof of the decomposability theorem. Conclusions This study describes the data relatability dependency and its properties. Its ability to represent many-to-many relationships exceeds those of functional dependencies and multivalued dependencies.
A necessary and sufficient condition for a relation to be decomposable is for the relation to possess a data relatability dependency. Literature Cited Arora, A. The information preserving properties of relational data base transformations.
