Uloga vještine vođenja projektnog menadžera tijekom izvedbe projekata

Na danasnjem kompetitivnom i promjenjivom tržistu posjedovanje samo tehnickih vjestina nije dovoljno za postizanje projektnog uspjeha koji zadovoljava sve korisnike projekta. Projektni menadžer osim vođenja projekta vodi i projektni tim, a to podrazumijeva posjedovanje vjestina koje ce biti usmjerene na povecanje efikasnosti i motivacije clanova tima. Putem sest skola misli je vidljivo kako je vodstvo kombinacija osobnih karakteristika i podrucja kompetencija. Odnosno, ono sto nekoga cini vođom je kombinacija vjestina i znanja s osobnim karakteristikama pojedinca. Kako ce se te karakteristike iskazivati ovisi o situaciji, stecenom znanju, kompetencijama i stilu vodstva. Vodstvo je vrlo kompleksno podrucje i postoje razni nacini putem kojih projektni menadžer može voditi tim i projekt. Ono sto je bitno je da se odabere pravi pristup koji ovisi o tipu projekta, kompleksnosti projekta i projektnom ciklusu. Spajanjem razlicitih pristupa i stilova vodstva s metodologijama i alatima projektnog menadžmenta te tipovima projekta dolazi se do matrice potencijalnih mogucnosti i ishoda. Ono sto je dokazano istraživanjima prezentiranim u ovom radu jest utjecaj kompetencija vođe (upravljacke, intelektualne, emocionalne) na efikasnost izvedbe projekta. Također, razliciti stilovi vodstva su prikladni za razlicite tipove projekta, a projektni menadžer ima ulogu stvoriti produktivno radno okruženje za clanove projektnog tima. Vjestine vođenja projektnog menadžera nemaju direktan utjecaj na projektni uspjeh, vec se do projektnog uspjeha dolazi zbog mnogo varijabli koje sudjeluju u projektnoj izvedbi. Potrebno je detaljno i jasno definirati ciljeve, budžet, vrijeme, potom oformiti projektni tim koji ima znanje i sposobnosti specificne za taj tip projekta. Važno je predvidjeti potencijalne probleme i promjene i imati alate kako ih ukloniti i kontrolirati. Iznimno je bitna jasna i koncizna komunikacija sa svim korisnicima projekta, a posebna važnost se stavlja na pravovremeno informiranje. Projektni menadžer treba u svim fazama kontrolirati i upravljati projekt i projektni tim. Projektni menadžer ce uz pravilnu primjenu svojih kompetencija i stila vodstva uz sve ostale varijable u procesu postici projektni uspjeh. Prema tome, vjestine vođenja nisu jedine odgovorne za projektni uspjeh, ali definitivno imaju utjecaja.
Displacement Capacity of Structural Frames Incorporating Moment Resisting Anchored Blind Bolted Connections

Welded connections with external or internal diaphragms that are connected to the beam flanges are currently the commonly used option for achieving a moment-resisting connection to concrete filled steel tubular columns in regions of high seismicity. This is not favoured and practical in Australia because of high expenses of site welding as well as the quality control requirements that are difficult and expensive to undertake. This paper presents results from an ongoing investigation into the development of moment resisting connections using innovative anchored blind-bolts in structural frames. Using different configurations of anchored blind bolts within concrete filled square hollow section (CFSHS) columns, moment resisting connections with different levels of stiffness and strength can be achieved. The behaviour of blind bolted connections has been determined using experimental data and elaborate FE modelling. These connections have been employed in a structural frame around the perimeter of the building. The moment resisting perimeter frames provide the lateral force resisting system. The stability of the frame and the strength hierarchy of the frame are investigated considering both material and geometrical non-linearities. The drift levels obtained using a response spectrum analysis based on the bare frame properties are compared to the results from an equivalent static analysis based on AS-1170.4. Finally, the capacity curve is achieved by performing a nonlinear push-over analysis on the structure and the capacity spectrum approach is used to determine whether the capacity is adequate for various earthquake levels.
Mechanisms of Gas Releases from Swine Wastes

Knowledge about release mechanisms of pollutant gases from animal manure is important for modeling and predicting gas release and emission, improving measurement accuracy, developing abatement technologies, and ensuring farm safety. This article presents research results on release behaviors of ammonia (NH 3 ), hydrogen sulfide (H 2 S), carbon dioxide (CO 2 ), and sulfur dioxide (SO 2 ) from swine manure. The study was conducted in a laboratory using 138 L laboratory reactors at 20 °C for 260 d. Gas release behaviors were investigated under transient conditions when manure was suddenly disturbed and under steady-state conditions at different reactor ventilation rates. Distinguishing release behaviors were observed and related to the different releases mechanisms of these gases. Convective mass transfer release governed NH 3 release and influenced H 2S and CO 2 releases. Solubility of gases played an important role in the convective releases. Higher solubility was related to higher convective release. "Bubble-release" was dominant in the releases of H 2S, SO 2 , and CO 2 . A new Bubble-release model was developed to explain release behavior characteristics related to these gases. Bubble-release was responsible for the reported phenomenon of "H 2 S Burst-release" that had been defined as sudden increases in H 2 S release by more than 100% as compared with previous releases in less than 1 h in deep-pit swine barns. Interactive release occurred among different gases via their different effects on the pH of surface manure. This study demonstrated that gas production in liquid manure and gas release from liquid medium into the immediate free air stream are two different processes that should be distinguished when addressing air pollution. Liquid manure containing dissolved gases and micro air bubbles serves as a reservoir before the gases are released to the free air stream. A "Reservoir-effect" was found to be considerable in this study because it held gaseous H 2 S for about 10 d before H 2 S bubbles started to release. Understanding gas release mechanisms can help to improve air quality sampling methodology. For example, to obtain accurate H 2 S emission factors at swine buildings, long-term monitoring with high-frequency (or continuous) and multipoint measurement is necessary to cope with temporal and spatial variations of the gas due to its Bubble-release behavior.
Oxygen Dissociation Curves of Muscle Haemoglobin

The function of muscle haemoglobin in respect to its combination with oxygen has now been made clear. It has been shown independently by two observers, Theorell (1934) and the present writer (R. Hill, 1933), to have a higher affinity for oxygen than the haemoglobin of circulation. The muscle haemoglobin has the positions of maximum absorption in the visible region of the spectrum at 5815 A and 5446 A, while those of the haemoglobin of the blood are at about 5770 A and 5420 A. It can be easily shown that an extract of red muscle having its ∝ band at about 5790 A (that is, in a position intermediate between the ∝ bands of the two haemoglobins) gives on partial evacuation a shift of the ∝ band to the red. This shows qualitatively the higher affinity for oxygen of the muscle haemoglobin. A convenient method of determining the dissociation equilibrium with oxygen on small amounts of dilute haemoglobin was then devised and applied to the problem. Meanwhile, Theorell achieved the isolation of muscle haemoglobin from the heart of the horse in a crystalline state and determined its dissociation curve by the established method for strong solutions. The results of these investigations are in agreement. Theorell’s series of investigations on the muscle haemoglobin of the horse are as elegant as they are complete. The present paper describes experiments on the heart muscle haemoglobin of the ox, sheep, dog, and goose. The characteristic hyperbolic shape of the muscle haemoglobin dissociation curve being found in each case. The method of determining the dissociation curve is given in detail. A dilute oxyhaemoglobin solution saturated with atmospheric oxygen is added in successive amounts to haemoglobin of the same concentration contained in an evacuated vessel. The liquid is shaken to obtain gaseous equilibrium, and spectroscopic determinations are made after each addition. The total pigment concentration in the tube is not altered during the experiment. We then have the required data for a dissociation curve.
Determination of styrene in selected foods

Styrene levels in 12 commodities were determined. The foods tested were wheat, oats, peanuts, pecans, coffee beans, tomatoes, peaches, strawberries, cinnamon, beef, chicken, and milk. The samples were collected in a manner that avoided contact with styrene or any type of plastic. Analytical measurements were performed using a dynamic heated headspace purge-and-trap extraction technique followed by quantification by selected ion monitoring capillary gas chromatography/mass spectrometry. Method blanks, duplicate samples, and samples fortified with benzene and styrene were used to assess method performance. The limit of detection of the method varied between food types but was generally less than 2 ng/g for styrene
Redes neuronales convolucionales para una clasificación precisa de imágenes de corales

Resumen—El reconocimiento de especies de corales basado en imágenes submarinas de texturas plantea una gran dificultad para los algoritmos de aprendizaje automático, debido a la naturaleza de los datos y las caracterı́sticas que tienen. Entre otras, encontramos que los conjuntos de datos no incluyen información sobre la estructura global del coral, que muchas especies de coral tienen caracterı́sticas muy similares y que definir los lı́mites espaciales entre clases es difı́cil ya que muchos corales tienden a vivir juntos. Por ello, la clasificación de especies de corales siempre ha requerido de la ayuda de un experto. El objetivo de este trabajo es desarrollar un modelo de clasificación precisa para imágenes de textura de corales. Nos hemos centrado en dos conjuntos de datos de imágenes de texturas y hemos analizado 1) varias arquitecturas de redes neuronales convolucionales, 2) transfer learning y 3) técnicas de data augmentation. Hemos alcanzado los porcentajes de clasificación más altos usando diferentes variaciones de ResNet en ambos conjuntos de datos.
Catalytic carbonization of an uncarbonizable precursor by transition metals in olivine cathode materials of lithium ion batteries

Herein, we report on catalytic effects of transition metals (Me) in phospho-olivines (LiMePO4) on carbonization of cetyltrimethylammonium bromide (CTAB). Carbon coating is the required process to enhance electronic conductivity of phospho-olivines that are used as cathode materials for lithium ion batteries. Primary particles of phospho-olivines were in situ coated with CTAB and the adsorbed carbon precursor was carbonized to provide an electrically conductive pathway. CTAB was successfully carbonized in a significant amount with Fe in phospho-olivines (LiFexMn1−xPO4 with x = 1 and 0.5) even if CTAB is thermally decomposed around 300 °C without any residual mass in the absence of the phospho-olivines. LiMnPO4 was the most inferior in terms of CTAB adsorption and thermal carbonization. LiNiPO4 and LiCoPO4 showed inefficient conversion of adsorbed CTAB to carbon even if their adsorption ability for CTAB is quite large. Also, the effect of the amount of carbon coating on LiFePO4 was investigated, leading to a conclusion that the carbon thickness balanced between electronic and ionic conductances results in the best electrochemical performances of lithium ion batteries specifically at high discharge rates.
Germanium and Germanium Compounds

Germanium is a semiconducting metalloid element found in Group 14 (IVA), Period 4 of the Periodic Table. Although it looks like a metal, it has a diamond cubic crystal structure and is fragile like glass. Its electrical resistivity is about midway between that of metallic conductors and good electrical insulators. The first significant use was in solid-state electronics, and, using germanium, the transistor was invented. The entire modern field of semiconductors owes it development to the early successful use of germanium. Germanium is used for optical fiber production, as polymerization catalysts, in infrared optics, in electronic and solar applications, and in other miscellaneous markets. Germanium usually occurs widely dispersed in minerals. Most germanium production has been from zinc smelters and copper smelters. Germanium also occurs in significant concentrations in many coals around the world. Germanium is quite stable in air up to 400°C, where slow oxidation begins. The metal resists concentrated acid and alkali. Many Ge alloys have been prepared and studied. No mineral is mined solely for its germanium content. Almost all of the Ge recovered worldwide is a by-product of other mining. Germanium compounds generally have a low order of toxicity.

The Nature, Number and Evolution of Hot‐Spots in Ammonium Nitrate

Ammonium nitrate (AN) is a commonly used fertiliser and also one component of the most widely used explosive in the world AN: Fuel Oil mixtures. This study uses a combination of high‐speed photography, UV/Visible spectroscopy and modelling. By using thin beds, <0.5 mm thick, with a porosity of 22%vol the number and evolution of hot‐spots in ammonium nitrate are monitored directly under dynamic loading conditions. The critical conditions for ignition are defined in terms of energy localisation mechanisms, temperature rise and inter‐communication between the hot‐spots.
Transformation from Multilamellar to Unilamellar Vesicles by Addition of a Cationic Lipid to PEGylated Liposomes Explored with Synchrotron Small Angle X-ray Scattering

PEGylated liposomes composed of a benzamidine derivative (TRX), hydrogenated soybean phosphatidylcholine (HSPC), and N-(monomethoxy-polyethyleneglycolcarbamyl) distearoyl phosphatidylethanolamine (PEG-PE) were examined in terms of how the addition of TRX affects their structures with small angle x-ray scattering (SAXS) as well as transmission electron microscopy (TEM). TEM images showed the presence of unilamella vesicles for both with and without TRX, though a small amount of multilamella vesicles were observed in absence of TRX. We analyzed SAXS profiles at contained TRX composition combined with contrast variation technique by adding PEG solution and unilamella vesicle model could be reproduced. Subsequently, we analyzed SAXS profiles at no TRX composition. The mixture model of unilamella and multilamella vesicle was reconstructed and we estimated about 10 % multilamella vesicles from a fitting parameter.
Bulk metallic glasses based on binary cerium and lanthanum elements

The authors reported the formation and dynamic and thermodynamic properties of bulk metallic glasses (BMGs) based on binary Ce and La elements, in which the compositions of Ce and La can be gradually changed in the range from 0 to 100at. % without deteriorating the glass-forming ability. The properties of the binary base glasses can be tuned by modification of the Ce and La compositions. The BMGs with unique features and tunable properties might provide a model system to investigate some long-standing issues in BMG-forming alloys. The approach has implication for designing BMGs with tunable properties.
Rôle de la phospholipase D1 dans le trafic membranaire : implication dans le développement neuronal et l'exocytose régulée

La croissance neuritique est un mecanisme complexe qui fait toujours l’objet d’intenses investigations. Les donnes actuelles ont permis de mettre en evidence l’implication de trois mecanismes principaux dans la croissance neuritique : i) la dynamique du cytosquelette, ii) le trafic intracellulaire et l’apport membranaire au niveau du cone de croissance et iii) la signalisation cellulaire, principalement via la voie MAPK-ERK1/2, qui abouti a la regulation de la transcription.La PLD1 et son produit l’acide phosphatidique semblent etre au centre de voies majeures impliquees dans le developpement neuronal. Mes travaux ont permis d’approfondir nos connaissances sur le role cellulaire de la PLD1 au cours de la croissance neuritique. J’ai montre que la PLD1 en collaboration avec la kinase RSK2 regule la fusion des vesicules positives pour Ti-VAMP/VAMP7 au cours de la croissance neuritique. D’autre part, j’ai etabli que la PLD1 joue un role important dans le maintien de la signalisation endosomale de la voie MAPK-ERK1/2-RSK2-CREB induite par les neurotrophines. J’ai egalement montre que la PLD1 regule l’activation de mTOR/p70S6K en reponse au BDNF. La deregulation des voies MAPK-ERK1/2 et mTOR/p70-S6K pourraient etre a la base de la reduction de l’arborisation dendritique et de la maturation des epines dendritique observee dans les neurones corticaux Pld1-/- en culture. En plus de l’implication de RSK2 dans la regulation de la PLD1, j’ai egalement montre que la PLD1 regule l’activation de RSK2 en reponse aux neurotrophines, probablement via une boucle de retrocontrole. Ainsi les donnes obtenus suggerent un lien fort entre les deux proteines au cours du developpement neuronal. A la lumiere de ces donnes, un dysfonctionnement de ce mecanisme pourrait expliquer le retard mental observe chez les patients atteints du syndrome de Coffin-Lowry cause par la perte de l’activite kinase de RSK2. D’autre part, les resultats obtenus suggerent un role de la PLD1 dans l’exocytose des vesicules.

Thus, 2,3-dihydro-7-methylhydrazone-4(1H)-phenanthrene was converted to its diazo compd. which cyclocondensed with 9H-thioxanthene-2-methoxy-9-thione to give I (R = MeO, R1 = H, R22 = S; R = H, R1 = MeO, R22 = S) which were desulfurized to give I (R = MeO, R1 = H, R22 = bond; R = H, R1 = MeO, R22 = bond). CD and UV spectra of the products were recorded. [on SciFinder (R)]

Confined molecular motions of globular proteins studied in powder samples and in solution

Internal molecular equilibrium fluctuations have been studied for α-amylase in two different types of samples. The comparison of incoherent neutron scattering from the enzyme in hydrated powders and in solutions gives insights into the protein - solvent interaction. Although the protein is already fully hydrated at h = 0.4 in a powder sample (the protein surface is completely covered with solvent), the proteins are characterised by a significantly larger structural flexibility in solution as compared proteins in powder samples. As obtained from model fits describing local diffusion, the results indicate that the higher mobility of solvent molecules in solution initiate additional fluctuations in the protein structure. Due to much more solvent surrounding the protein in solutions, the picosecond fluctuations of the enzyme seem to be damped, indicated by smaller amplitudes and a weaker temperature dependence as compared to powder samples.
Regioselective polymerization of divinyl sebacate and triols using lipase catalyst

The lipase-catalyzed regioselective polymerization of divinyl sebacate and triols has been carried out. Immobilized lipase derived from Candida antarctica induces the polymerization of divinyl sebacate and glycerol, yielding a soluble polymer of relatively high molecular weight. NMR analysis showed that 1,3-diglyceride is a main unit and the branching unit (triglyceride) is contained in the resulting polymer. These data indicate that the polymerization proceeds regioselectively to give the reactive polyester having a pendant hydroxy group.
Rapid Low-Temperature Synthesis of Porous ZnO Nanoparticle Film by Self-Hydrolysis Technique

Porous nano-scale ZnO particle film was rapidly synthesized from a mixing solution of zinc acetate dihydrate – acetone at about 90 °C. The crystal structure and morphology were clarified by the X-ray diffraction and a field emission scanning electron microscope. The evaporation of higher vapor pressure acetone resulted in the hydrolysis of zinc salt in itself crystalline water. Three morphologies of ZnO (dispersed nanoparticles, dispersed bread chip-shaped particles and flower-like bread chip-shaped assemblies) were observed.
CULTIVATION OF MELISSA OFFICINALIS ,L IN THE NORTH MIDDLE NILE DELTA REGION: B.EFFECT OF PLANTING SPACES AND ACTIVE DRY YEAST

Two field experiments was established at Sakha Agricultural Research Station during the two seasons of 2008/2009 and 2009/2010 to evaluate the effect of planting spaces and active dry yeast on the growth ,yield and oil components of Melissa officinalis ,L . Three planting spaces (30, 40 and 50 cm) and four applications of active dry yeast (control, 5, 10 and 15gm / l) were used in the two seasons. The obtained results showed that wider plant spacing showed the greatest effect on growth parameters and chemical constituents. Similarly, active dry yeast levels had a promoting influence on most of the vegetative growth parameters and accelerated essential oil accumulation and chemical constituents including chlorophyll a ,b and total content and N,P and K%. The wider space between plants (40 or 50 cm) combined with maximum rate of dry yeast (10 or 15g/ l) had a favorable effect on the most growth characters and chemical constituents. The main constituent of the essential oil was, geranial (citral A) followed by camphene. Generally, it can be concluded that there is no significant difference between wider distance (50 cm) and medium one (40 cm) and rate of dry yeast (10 and15g/ l). So, it can be recommended to cultivate at distance of (40 cm) combined with applying (10 g/ l) of active dry yeast.
Photoresponse of photodiode arrays for solid-state image sensors

A closed-form analytical expression for diffusion-limited photocurrent in a closely spaced photodiode array is presented with reference to modern CMOS imaging arrays. The analysis makes use of the fact that the current density at the peripheral edges of the photodiode in a closely spaced array has a maximum value near the surface and decays approximately in a linear fashion with the depth into the substrate. The approximated lateral current density at the peripheral edge is then used to derive an expression for the overall peripheral photocurrent. The final expression shows good agreement with the experimental results.
Extraction of carbon‐14 from biological samples by wet oxidation

Abstract An improved method is described for the extraction of 14C from biological samples, based on the wet oxidation techniques of Snyder and Trofymow6. Evolved 14CO2 is trapped in a 2M NaOH solution, and subsequently mixed in a scintillation cocktail for s counting. Recovery of 14C is consistent between batches, with an average recovery of 97.2% over fifteen standards. The technique described does not involve large capital expenditure and is relatively rapid.
