Glasnik ?umarskog Fakulteta , 2012, DOI: 10.2298/gsf1206029a
Abstract: A project is a task comprising a set of interrelated activities requiring time and resources for their execution. It is often the case that during the construction of longitudinal and cross section structures for the regulation of a torrential catchment the required resources (labour, materials, mechanization, and finances) are often limited and because of that we face the problem of their efficient use. This paper deals with the problem of planning the execution of river regulation works on the Jela ni ka River with the aim to minimize the time extension due to limited resources. In the planning phase of project realization labour force is the limited resource. Heuristic techniques, i.e. the Gray-Kidd algorithm with the use of MS Project software were applied in the distribution of resources for the purposes of optimal labour engagement. This method uses the data acquired by the CPM method of network planning as input elements. Through more iterations, by moving noncritical and then critical project activities, the minimal extension of project duration was achieved by engaging more labour force. Therefore, the proposed heuristic and CPM method performed well in resolving the resource-constrained project scheduling problem.

Agriculturae Conspectus Scientificus (ACS) , 2007,
Abstract: Sensory quality is important in assessing cultivars for fresh consumption as well as for the processing industry. Important quality attributes for fresh consumption were found to be colour, taste, flavour and texture attributes. Strawberries (Fragaria x ananassa Duch.) have unique, highly desirable taste and flavour and are one of the most important cultivated berry fruits in Croatia. Today, consumers are increasingly better informed about diet and health, and as a result, desire more “healthy“ food, which offer high quality, safety and optimum nutrient balance. The increasing demand for organic food has focused interest based on claims that an organic product tastes “different“, is “preferred“ and is “more healthy“. It has implicit expectation that the improvement is due to the way the food is grown. The topic of organic food and organic agriculture attracts considerable public, commercial and research interest. The purpose of the present investigation was to profile the sensory characteristics of fresh fruit and its purées in two strawberry cultivars, ‘Maya’ and ‘Queen Elisa’, conventionally and organically grown in Croatia. Quantitative descriptive analysis (QDA) was used to describe the sensory properties of fresh fruit as well as its purées. All obtained results were statistically evaluated. Conducted sensory evaluation indicated that there were slightly expressedsome differences in sensory attributes observed by panelists between two different cultivars and two type of cultivation but they did not show significant differences in any sensory attribute when dealing with two different strawberry cultivars or two types of cultivation.
Reversal deterioration of renal function accompanied with primary hypothyrodism

Vojnosanitetski Pregled , 2012, DOI: 10.2298/vsp1202205d
Abstract: Introduction. Hypothyroidism is often accompanied with decline of kidney function, or inability to maintain electrolyte balance. These changes are usually overlooked in everyday practice. Early recognition of this association eliminates unnecessary diagnostic procedures that postpone the adequate treatment. Case report. Two patients with elevated serum creatinine levels due to primary autoimmune hypothyroidism, with complete recovery of creatinine clearance after thyroid hormone substitution therapy are presented. The first patient was a young male whose laboratory tests suggested acute renal failure, and the delicate clinical presentation of reduced thyroid function. The second patient was an elderly woman with a history of a long-term signs and symptoms attributed to ageing, including the deterioration of renal function, with consequently delayed diagnosis of hypothyroidism. Conclusion. Serum thyrotropin and thyroxin levels measurement should be done in all cases of renal failure with undefined renal desease, even if the typical clinical presentation of hypothyroidism is absent. Thyroid hormone assays sholud also be performed in all patients with chronic kidney disease whose kidney function is rapidly worsening.

Pseudo-integrable billiards and arithmetic dynamics
Vladimir Dragovi,Milena Radnovi?
Physics , 2012,
Abstract: We introduce a new class of billiard systems in the plane, with boundaries formed by finitely many arcs of confocal conics such that they contain some reflex angles. Fundamental dynamical, topological, geometric, and arithmetic properties of such billiards are studied. The novelty, caused by reflex angles on boundary, induces invariant leaves of higher genera and dynamical behaviour different from Liouville-Arnold's theorem. Its analogue is derived from the Maier theorem on measured foliations. A local version of Poncelet theorem is formulated and necessary algebro-geometric conditions for periodicity are presented. The connection with interval exchange transformation is established together with Keane's type conditions for minimality. It is proved that the dynamics depends on arithmetic of rotation numbers, but not on geometry of a given confocal pencil of conics.
Systems of Kowalevski type, discriminantly separable polynomials and quad-graphs
Vladimir Dragovi,Katarina Kuki?
Mathematics , 2011,
Abstract: We establish a new class of integrable {\it systems of Kowalevski type}, associated with discriminantly separable polynomials of degree two in each of three variables. Defining property of such polynomials, that all discriminants as polynomials of two variables are factorized as products of two polynomials of one variable each (denote one of the polynomial components as $P$), lead to an effective integration procedure. In the motivating example, the celebrated Kowalevski top, the discriminant separability is a property of the polynomial defining the Kowalevski fundamental equation. We construct several new examples of systems of Kowalevski type, and we perform their explicit integration in genus two theta-functions. One of the main tasks of the paper is to classify such discriminantly separable polynomials. Our classification is based on the study of structures of zeros of a polynomial component $P$ of a discriminant. From a geometric point of view, such a classification is related to the types of pencils of conics. We construct also discrete integrable systems on quad-graphs associated with discriminantly separable polynomials. We establish a relationship between our classification and the classification of integrable quad-graphs which has been suggested recently by Adler, Bobenko and Suris. As a fit back, we get a geometric interpretation of their results in terms of pencils of conics, and in the case of general position, when all four zeros of the polynomial $P$ are distinct, we get a connection with the Buchstaber-Novikov two-valued groups on $\mathbb {CP}^1$.
New Examples of Systems of the Kowalevski Type
Vladimir Dragovi,Katarina Kuki?
Mathematics , 2011, DOI: 10.1134/S1560354711050054
Abstract: A new examples of integrable dynamical systems are constructed. An integration procedure leading to genus two theta-functions is presented. It is based on a recent notion of discriminantly separable polynomials. They have appeared in a recent reconsideration of the celebrated Kowalevski top, and their role here is analogue to the situation with the classical Kowalevski integration procedure.
Delving into the Boardroom “Black Box”: A Research Model of “Board Learning Capability” (BLC)  [PDF]

Abstract: This paper aims to shed light into boardroom processes by bringing together the literature on organization behaviour and that of boardroom process in order to form a model of boardroom learning capability. Board process is viewed as primarily a learning process whereby individual members with their knowledge, skills and external networks engage in a collective learning process that culminates in a “shared understanding” about the problems and respective solutions and increased “board social capital”. It can be argued that boards that do better at this “collective learning process” will display greater effectiveness and ultimately better firm performance. In learning organisation’s terms, one can speak of “board learning capability” (BLC). The chairman of the board has a pivotal role in facilitating and mastering the collective learning process in the boardroom. Central to our model are the interplay between the “chairman role and skill set” and the “board learning challenges”. Building on research literature that focuses on learning organisations and on boardroom processes, we propose a model of “board learning capability” (BLC), which could shed additional light on the boardroom process dynamics. In the future, an organisation could develop a “board’s learning capability” measure to complement “good governance” indices which rely heavily on structure and composition proxies, despite limited empirical evidence. Empirical testing of the model can be of value for boardroom development and for risk and reputational concern minimization by uncovering differences in “boardroom learning capability” in different governance domains.
