Fiscal Deficit and its effects on economic growth: Empirical evidence
The main purpose of this paper is to assess the impact of the deficit on GDP growth for the Eurozone area, using panel data for a period from 1995 to 2015, with a total of 257 observations. In order to conduct the study and come up with results, we have used a multiple linear regression model with the least-squares regression. Consequently, in order to test the data used in the model, we have applied diagnostic tests, such as the Durbin-Watson test to analyze the correlation of serial correlation, as well as the Breusch-Pagan test for heteroskedasticity. The test results prove that there is no heteroskedasticity and at the same time there are strong indications that the model has no relation between serial correlation. The results presented in our study show that the variables, deficit ratio to GDP, is statistically significant with a positive sign and as a result, we have the growth of the deficit ratio with GDP having a positive impact on the economic growth ratio.

Fireworks-related Injuries during New Year celebrations in Kosovo: A comparison of the years 2008 and 2009
Background: Fireworks related injuries in children occur in Kosovo particularly during New Year celebrations.Aim: To report the pattern of fireworks- related injuries in childrenup to 16 years of age treated at the Emergency Center and Plastic Surgery,University Clinical Centre of Kosovo during the 2008 and 2009 New Year celebrations.Methods: Retrospective review of hospital recordsResults: During the New Year celebrations in 2008, a total of 65 caseswere admitted, 32 (49.2%) of who were children injured by fireworks. The ages of the children ranged from 5 to 16 years with a mean of 10.5years. The modal age affected was the 10 – 14 year-old group (53.6%). Boys constituted 93.8% of patients and girls 6.3%. During the 2009 New Year celebration, 17 cases were admitted with fireworks injuries, 12 (70.58%) of who were children ranging in age from 8 to 15 years (mean 11.5 years) with a modal age group of 10 – 14 years (66.7%). Boys accounted for 88.3% and girls for 16.7% of patients.Conclusions: The frequency of fireworks injuries reduced appreciablyafter introduction of laws restricting sales of fireworks devices and banningtheir use by children.Recommendations: It is recommended that parents play a greaterrole in controlling the activities of their children during festivities. Thegovernment and police should also ensure compliance with the law onthe use of fireworks during the holidays.Key words: fireworks injury, epidemiology, wounds, prevention
Co-crystallisation of cytosine with 1,10-phenanthroline: computational screening and experimental realisation
Attempts to co-crystallise the nucleobases adenine, thymine, guanine, and cytosine with 1,10-phenanthroline by ball milling and solvent evaporation methods are described. A 1:1 co-crystal of cytosine and 1,10-phenanthroline can be obtained by grinding or by solvent evaporation. The structure contains two crystallographically independent cytosine and two independent 1,10-phenanthroline molecules (Z′ = 2). The cytosine molecules form two similar but crystallographically independent hydrogen-bonded chains, while the 1,10-phenanthroline molecules are arranged in π-stacks. Between the chains of cytosine and the π-stacks exist N-H⋯N and C-H⋯N interactions. Crystal structure prediction (CSP) calculations were applied to all four systems to assess their potential for co-crystallisation as well as the likely structures and intermolecular interactions that could result from co-crystallisation. Calculations on the cytosine system demonstrate that co-crystallisation results in a lower energy than the crystalline forms of the two starting materials, in line with the co-crystal formation observed. For the systems which did not form a co-crystal, CSP was used to explore potential packing arrangements, but found none which were lower in energy than that of the pure crystalline forms. In these cases there is significant disruption to the nucleobase hydrogen bonding between the pure compound and the hypothetical co-crystal. For pure adenine and guanine, the hydrogen-bonded ribbons form sheets which must be broken, whereas for thymine, the lack of hydrogen bond donors does not allow the hydrogen bonding present for pure thymine to be maintained while forming thymine-1,10-phenanthroline hydrogen bonds

A 1 : 1 co-crystal of cytosine and 1,10-phenanthroline can be obtained by grinding or by solvent evaporation. The structure contains two crystallographically independent cytosine and two independent 1,10-phenanthroline molecules (Z? = 2). The cytosine molecules form two similar but crystallographically independent hydrogen-bonded chains, while the 1,10-phenanthroline molecules are arranged in ?-stacks. Between the chains of cytosine and the ?-stacks exist N–H?N and C–H?N interactions.

Spectrum of Higher Derivative 6D Chiral Supergravity
Gauged off-shell Maxwell-Einstein supergravity in six dimensions with N=(1,0)
supersymmetry has a higher derivative extension afforded by a supersymmetrized
Riemann squared term. This theory admits a supersymmetric Minkowski x S^2
compactification with a U(1) monopole of unit charge on S^2. We determine the
full spectrum of the theory on this background. We also determine the spectrum
on a non-supersymmetric version of this compactification in which the monopole
charge is different from unity, and we find the peculiar feature that there are
massless gravitini in a representation of the S^2 isometry group determined by
the monopole charge.Comment: typos correcte
SU(2) Reduction of Six-dimensional (1,0) Supergravity
We obtain a gauged supergravity theory in three dimensions with eight real
supersymmetries by means of a Scherk-Schwarz reduction of pure N=(1,0)
supergravity in six dimension on the SU(2) group manifold. The SU(2) Yang-Mills
fields in the model propagate, since they have an ordinary kinetic term in
addition to Chern-Simons couplings. The other propagating degrees of freedom
consist of a dilaton, five scalars which parameterise the coset SL(3,R)/SO(3),
three vector fields in the adjoint of SU(2), and twelve spin 1/2 fermions. The
model admits an AdS_3 vacuum solution. We also show how a charged black hole
solution can be obtained, by performing a dimensional reduction of the rotating
self-dual string of six-dimensional (1,0) supergravity.Comment: Latex, 24 page
A hierarchical reference-based know-why model for design support of sustainable building envelopes
In current complex building designs, sustainability assessments are often performed after project completion, with limited impact on building performance which results in missed goals in terms of quality, cost, and time. We address this problem by proposing a hierarchical reference-based know-why model to answer the research question “what is a suitable decision support model to successfully integrate the sustainability requirements in the early design phase of buildings?”. The model presents a process that incorporates a life-cycle perspective and calculates design alternatives based on a defined reference and the DGNB building certification system. The results show that criteria synergies and trade-offs can be identified, leading to improved design by engineers and better building performance. Our findings pave the way for full integration of the model into building information modeling, combined with artificial intelligence. This can help manage the complexity of the sustainable design process on the path to carbon-neutral buildings
