The Influence of Feeding Regimen on the Composition of the Fat Pads in the Bovine Digital Cushion  [PDF]
Martha Rber, Vera Letter, André Chassot, Hans Geyer, Martin R. L. Scheeder
Agricultural Sciences (AS) , 2015, DOI: 10.4236/as.2015.69085
Abstract: The effect of an intensive/extensive feeding regimen on lipid content and fatty acid composition of the bovine digital cushion was investigated in 32 beef cattle of both genders, divided in 2 groups (16 per intensive/extensive feeding). The beef cattle were calves of different suckler cow husbandries. After the separation from their mothers at the age of 10 months, they were differently fed for 5 months. The animals were slaughtered at the age of 15 months with a mean body weight of 450 kg. The macroscopic claw examination of all beef cattle was made at two defined claws at the beginning of the trial and after slaughter. For applicatory reasons, the fat pads of the claws could only be prepared after slaughter. Samples from fat pads at defined locations of the digital cushion were analysed for lipid content and fatty acid composition determination. Additionally, samples from the digital cushions and few samples of subcutaneous tissue of 9 dairy cows served as comparison. These slaughterhouse cows were mainly fed with hay and grass; further data however were not available. The digital fat pads and the subcutaneous fat of both groups showed obvious differences in the fat content and the fatty acid composition. The fat pads of the intensive fed animals contained fewer lipids and more omega-6-fatty acids. The extensive fed animals had distinctly more omega-3-fatty acids. In the subcutaneous fat of the intensive fed animals, more omega-6-fatty could be found and more omega-3-fatty acids in the extensive fed animals. These results indicate that the feeding can influence the lipid content and the fatty acid composition. The macroscopic hoof horn quality grade of the intensive fed group was better than the extensive fed group. The digital pads of the dairy cows contained more lipids, more monounsaturated fatty acids and less omega-6-fatty acids.
A NEW SPECIES OF FRESHWATER CRAB OF THE GENUS NEOSTRENGERIA PRETZMANN, 1965, FROM META DEPARTMENT, COLOMBIA (CRUSTACEA: DECAPODA: PSEUDOTHELPHUSIDAE)
CAMPOS,MARTHA R.;
Caldasia , 2011,
Abstract: a new species of freshwater crab of the pseudothelphusid genus neostrengeria pretzmann, 1965, is described and illustrated. this discovery means the genus now contains 25 species, all of which are endemic to the eastern andes of colombia. the new species is distinguished from their congeners primarily by the morphology of the first male gonopod, particularly by the shape of the accessory lobe, outline of apex and mesial lobe.
Promoviendo salud en la comunidad: la terapia comunitaria como estrategia
Fuentes R,Martha;
Revista Facultad Nacional de Salud Pública , 2011,
Abstract: objective: to identify, by assessing the records of community therapy meetings, the everyday problems that affect communities in order to understand and map the pain and suffering expressed by the participants. methodology: the records created by the therapists after each meeting were used for data collection. the following two topics were chosen for analysis purposes: the problems that were presented and the ones that were chosen. likewise, analysis categories were identified based on the frequency with which they were mentioned by the participants. the records of 774 meetings were analyzed. such meetings took place from august, 2006 to december, 2008. an average of 9 to 20 people attended each meeting. results: openness, freedom, warmth, and respect were characteristics of these meetings. the most common problems were: domestic violence, sexual abuse, divorce, discrimination, feelings of guilt, abandonment, rage, fear, negligence, problems with children, partners, co-workers or neighbors, losing one?s job, one&38217;s loved ones or one?s material possessions, drug addiction, alcoholism, smoking, etc. conclusions: community therapy has led not only to identify the people who really are in need of treatment, but also contributed to reduce the demand for the municipality?s health services. having people meet without judging them by what they say, feel or think makes it easier for them to cope with their suffering and fears. it also creates social support networks, develops better attitudes of solidarity, responsibility and affectiveness, empowers the people and the community, and makes it easier to find better ways of overcoming problems. at the same time, it makes it possible to learn how people live and cope with their daily problems, thus allowing them to reframe these problems, and enabling the development of more effective care.

Minimal Critical Sets of Refined Inertias for Irreducible Sign Patterns of Order 2  [PDF]
Ber-Lin Yu
Advances in Linear Algebra & Matrix Theory (ALAMT) , 2013, DOI: 10.4236/alamt.2013.32002
Abstract:

Let S be a nonempty, proper subset of all refined inertias. Then, S is called a critical set of refined inertias for ireducible sign patterns of order n if \"\" is sufficient for any sign pattern A to be refined inertially arbitrary. If no proper subset of Sis a critical set of refined inertias, then S is a minimal critical set of refined inertias for sign patterns of order n . In this paper, all minimal critical sets of refined inertias for irreducible sign patterns of order 2 are identified. As a by-product, a new approach is presented to identify all minimal critical sets of inertias for irreducible sign patterns of order 2.

Synergetic Use of Satellite Image and DEM for Identification of Landforms in a Ridge-Valley Topography  [PDF]
Tapas R. Martha, Rajarshi Saha, K. Vinod Kumar
International Journal of Geosciences (IJG) , 2012, DOI: 10.4236/ijg.2012.33051
Abstract: Multispectral satellite image and digital elevation model (DEM) have emerged as the primary data sources for the mapping of landforms. They offer an opportunity to gain a fresh insight into the geomorphology of an area through landform identification using spatial, temporal, spectral and radiometric resolution of satellite images, and through the synergetic approach using DEM derivatives such as profile, slope, hill shading, contour pattern and 3-D flythrough visuals. This paper demonstrates an integrated study of Resourcesat-1 LISS III (23.5 m) image with ASTER DEM (30 m) for the identification of landforms in a rugged topography where conventional field based methods are difficult to adopt due to terrain inaccessibility. Satellite image aided by 3-D visualisation helped in accurate identification of landforms such as hogback, cuesta, plateau top and intermontane valley. The results showed that although denudational processes are active in this area, structural imprints of the strata that is mostly of proterozoic era, are still preserved.

M. Beránková,M. Hou?ka,R. Kvasnicka
AGRIS on-line Papers in Economics and Informatics , 2010,
Abstract: In this work, we provide two case studies on interoperability and transfer of knowledge in the environment of acompany dealing with plant protection. We find that the area of plant protection is highly oriented on workingwith knowledge. In this case interoperability of knowledge can play an important role in acquiring knowledgefrom different environments to solve specific problem in companies dealing with plant protection. Nevertheless,the concept of interoperability is well-developed on the level of data and information only.We stem from our previous works, where we defined a logical concept for the interoperability of knowledge onthe level of knowledge units. The objective of this work is to show how to apply our process model ofknowledge interoperability in a particular plant protection company. Two case studies are provided in order todemonstrate distinguishing between simple knowledge transfer and knowledge interoperability.
Theoretical and Practical Decisions of Bankruptcy as one of Dynamic Alternatives in Company‘s Performance

Engineering Economics , 2007,
Abstract: The problems of company’s alternative develop-ment, its bankruptcy and bankruptcy prediction have become very relevant in Lithuania during the last dec-ades. According to the different authors, every bank-ruptcy is assessed as its local phenomenon as well as the macro economic appearance, which brings a lot of economic and social consequences for people who lose their jobs as well as for appropriate institutions. Theo-retical results of research are often integrated into the process of company’s administration, however the ris-ing number of bankruptcies shows that bankruptcy pre-diction is not assessed properly in the practical level of company’s management. The administration practice of failed companies in Lithuania shows that this process often determines negative results in the company and is very painful for its employees as well as for its creditors and owners. The changes of external conditions and the pressure that company experiences in the nowadays market economy often go the limits of the company’s management competence. Working companies face the global transformation, which is very specific, so it is not always possible to apply the traditional means of crisis management in their administration. Bankruptcy, as one of crisis development alternative in the company, is pos-sible to avoid properly estimating bankruptcy probabil-ity and applying prevention means in company’s per-formance in time. When bankruptcy mechanism is late, to start new activities or to reorganize the company is often impossible because of the short company’s re-serves. Bankruptcy prediction should be based on the continual observation and assessment of its financial state in order to notice the very first bankruptcy fea-tures, to define their reasons and to estimate their solu-tion possibilities. The article deals with the theoretical dynamic alternatives of crisis development in a com-pany. Bankruptcy features are analyzed applying dis-criminant analysis.
Pseudogaps and their Interplay with Magnetic Excitations in the doped 2D Hubbard Model
R. Preuss,W. Hanke,C. Gr?ber,H. G. Evertz
Physics , 1997, DOI: 10.1103/PhysRevLett.79.1122
Abstract: On the basis of Quantum Monte Carlo simulations of the two-dimensional Hubbard model which cover the doping range from the under- to the over-doped regime, we find that the single-particle spectral weight $A (\vec k,\omega)$ qualitatively reproduces both the momentum ($d_{x^2-y^2}$--symmetry) and doping dependence of the pseudogap as found in photoemission experiments. The drastic doping dependence of the spin response $\chi_{s} (\vec q,\omega)$ which is sharp in both $\vec q (\approx(\pi,\pi))$ and $\omega$ in the under-doped regime but broad and structureless otherwise, identifies remnants of the antiferromagnetic order as the driving mechanism behind the pseudogap and its evolution with doping.
