Uloga bioetike u obrazovanju inženjera okoliša
Authors: Loborec Jelena , Zavrtnik Saša , Žubčić Damir
Published: December 2019

Rad pruža osvrt na potrebu uvođenja kolegija koji bi se bavio bioetičkim konceptima u visokoškolskom obrazovanju na primjeru studijskog programa Inženjerstvo okoliša na Geotehničkom fakultetu Sveučilišta u Zagrebu. Radi se o studiju iz polja Temeljnih tehničkih znanosti gdje se moralno-etički principi često samo načelno podrazumijevaju, najčešće u vidu tehničke etike. Iako profit tu igra veliku ulogu, moramo sagledati struku u širem kontekstu. U sklopu studija postoje kolegiji koji se u određenoj mjeri dotiču integrirane bioetičke tematike, ali u nedovoljnoj mjeri. U posljednje vrijeme počinje se prepoznavati mjesto koje bi bioetika mogla i trebala zauzimati u obrazovanju budućih inženjera okoliša s obzirom na to da će oni svoj profesionalni rad usmjeravati prema različitim aspektima. Pri tome treba imati na umu da njihovo inženjersko djelovanje utječe na kvalitetu života i zdravlje ljudi, kao i na dobrobit drugih živih bića s kojima smo neraskidivo povezani.

Effect of leaders' implicit followership prototypes on employees' internal and external marketability
Authors: Su Xin , Gao Peng , He Ying , Zhu Xuzhen
Published: December 2019

To examine if leaders' implicit followership theory can be transferred from the behavior level to the competence level, we used a social information processing perspective to investigate the effects of leaders' implicit followership prototypes on employee marketability. Participants
were 331 employees of companies in China, who completed measures of their leaders' implicit followership prototypes, internal and external marketability, and psychological empowerment, and their leaders rated the employees' in-role performance. Results showed that leaders' implicit followership
prototypes were positively correlated with employees' internal and external marketability, these 2 effect mechanisms were partly mediated by employees' psychological empowerment, and employees' in-role performance negatively moderated both the effects of leaders' implicit followership prototypes
and the mediating effect of psychological empowerment in the relationship between leaders' implicit followership prototypes and employees' marketability. Our findings enrich research into implicit theories, marketability as an employee competence, and social information processing within the
context of leadership, and have implications for management practice.

Geoinformation mapping of landscapes on the example of the Primorskiy Ridge (Baikal region)
Authors: Vanteeva Yu.V. , Rasputina Е.А. , Solodyankina S.V.
Published: December 2019

The authors present the results of geoinformation mapping the Primorskiy Ridge landscapes using Landsat 8 satellite images, the digital elevation model SRTM and the factor-dynamic classification of geosystems. At the first stage, the remote sensing data for different seasons were classified using the ISODATA method. Then, using the digital elevation model, the landforms were classified basing upon the topographic position index. According to combining the classification parameters of one of the space images and digital elevation model, each polygon is automatically assigned to a certain preliminary type of landscapes using boolean expressions. Legend adjustments were made basing upon the fieldwork materials. As a result, a digital landscape map of the southern part of the Primorsky Ridge was created; it reflects the landscape structure at the level of facies groups and contains attributive information about the landform, altitude, slope and aspect, topographic wetness index. The analysis of the landscape pattern showed a high fragmentation of landscape polygons, formed due to overlay operations, which indicates the need for generalization of landscape contours.
Irrigated soil mapping of Volgograd region (Svetly Yar area) using Landsat-8 and Canopus-B satellite images
Authors: Chursin I.N. , Aleshina A.R. , Gorokhova I.N.
Published: December 2019

The autors present the results of studying and mapping long-term irrigated soils using remote information from the satellite Ladsat-8 on the example of an irrigated area of the south of Russia (Svetloyarsky irrigation system, Volgograd region). Natural features and history of developing the area under study are considered, the results of field research and visual analysis of remote information are given; it enabled interpreting features of irrigated soils and the nature of using agricultural fields. Basing on the developed characteristics, a remote image was classified. The classification process was carried out in two stages, with a preliminary preparation of the image. At the first stage, agricultural use of fields was classified, at the second (using the CART algorithm “decision trees”) – the allocation of irrigated soils within each field. Basing on the classification results, a map of irrigated soils was created, taking into account their agricultural development.

Authors: Obidenko V.I.
Published: December 2019

In the article the researches on developing modern methodology of supporting the national program “Digital economy of the Russian Federation” with geospatial data and, first of all, its base component, the systems of coordinate support are presented. As the main sentences of upgrading coordinate support it is offered to pass to kinematic model of evolution of coordinates in the state coordinate system GSK-2011 completely. The coordinates in this model are to be given to the consumer not on some separate instants (an initial epoch of installation of a coordinate system, an epoch of the last adjustment etc.), but for the current date, using a federal network of differential geodetic stations as the main tool for implementing this methodology. In order to avoid inconveniences of application the reference system for practical operations (as the coordinates are time-dependent), it is offered to use the additional coordinate system, “fixed” to an appropriate tectonic plate, spun round Euler’s pole within the state reference system GSK-2011.

Determination of optimal ultrasound conditions for preparation of O/W emulsions with encapsulated juniper berry essential oil (Juniperus communis L.)
Authors: Bajac Jelena , Nikolovski Branislava , Nesterovic Andrea , Loncarevic Ivana , Petrovic Jovana
Published: December 2019

The microencapsulation of essential oils can provide their evaporation and
oxidation protection, flavor retention or/and masking of unpleasant taste.
The microencapsulation process involves emulsions preparation and drying of
the obtained emulsion droplets. The aim of this study is the determination
of optimal conditions for preparation of the stable O/W emulsions containing
juniper berry essential oil with minimal droplet size, as a preparatory
stage for microcapsule formation. As the first step for pre-emulsions
preparation, homogenization at 10000 rpm for 5 min. was chosen, which gave
emulsions with droplet size between 1.82 and 2.51?m, depending on
concentrations of the surfactant (Tween 20) and encapsulated essential oil.
The second step was ultrasound emulsification during 5 minutes at a
frequency of 99%, using pulsed 10:10 s (ON/OFF) ultrasound treatment, which
was chosen as an optimal, creating emulsions of droplet sizes of 320 nm in
diameter (for 5% essential oil and 1% Tween 20). The addition of wall
material changed the size and stability of emulsions, which depends on type
of biopolymer and its surface competition with used surfactant. The
maltodextrin (MD), gum arabic (GA) and their mixture in equal ratio were
used. GA emulsions can be singled out as the most stable without used
surfactant, with D4,3 = 1.11 ? 0.003 ?m. Using MD as a wall material
requires addition of surfactant (1% w/v) to form stable emulsions. The
mixture of MD/GA can be used with or without surfactant. The addition of
Tween 20 (1% w/v) decreases droplet size from 14.86 to 0.99 ?m, while
utilization of the ultrasound contributes to the droplet size decrease and
emulsions stability.

Published: December 2019

In the past few decades the diet preparation in feed production has evolved
towards more complicated technological operations, which include different
liquid addition. A wide scale of different liquids is used in contemporary
animal feed production, from oils and glycerol to more expensive products in
a liquid form, such as enzymes, flavourings, amino acids, vitamins and
others. In the presented study the liquid addition in feed production was
observed, with a specific goal to investigate the spraying systems in order
to better understand the effects of fluids, such as soybean oil and
glycerol, on feed production. The dispersion angles of spraying nozzle for
glycerol and soybean oil were determined as an indicator of the uniform
application of liquids during feed production. Dispersion of the material
was accomplished using the two-fluid nozzle. The performance of Artificial
Neural Network (ANN) was compared with experimental data in order to develop
rapid and accurate method for prediction of dispersion angle. The ANN model
showed high prediction accuracy (r2 = 0.945).

Published: December 2019

Algae are a significant part of biodiversity and studies on their bioactive
compounds are numerous. The aim of this work was to study the fatty acid
profile of Cystoseira sauvageauana and Laurencia pinnatifida collected from
the Algerian coast. Different conventional and alternative methods were used
for lipids extraction and GCMS analysis for fatty acids methyl esters
identification. The lipids content was low (<1%) for the two species while
the highest yield was obtained by Folch method assisted with a pulsed
electric field. The identified fatty acids in both species ranged from C14
to C20 carbon atoms, of which palmitic acid was the major compound.
Regarding polyunsaturated fatty acids, in C. sauvageauana arachidonic acid
(C20:4) was the major constituent in extraction methods using the
chloroform: methanol mixture as solvent, while in the method using hexane,
linoleic acid (C18:2) was found as the main constituent. In L. pinnatifida,
eicosapentaenoic acid (C20:5) was the major fatty acid followed by
arachidonic acid. In comparison between the two species the best
polyunsaturated fatty acids/saturated fatty acids ratio was found in
ultrasound assisted methods in C. sauvageauana. The omega-6/omega-3 ratio
was considered satisfactory for both species; however, it was better in L.
pinnatifida. The obtained results showed the influence of the solvent and
the extraction method on the total lipid yield and the fatty acids
composition in algal extracts. In addition, these two species could find an
application in the field of food and pharmaceuticals.
Computational modeling of distribution coefficients and their correlations with pharmacokinetic properties of 17α-picolyl and 17(E)-picolinylidene androstane derivatives
Authors: Kovacevic Strahinja , Karadzic-Banjac Milica , Podunavac-Kuzmanovic Sanja , Ajdukovic Jovana
Published: December 2019

The present study describes the computational modeling of distribution
coefficient (logD) of 17?-picolyl and 17(E)-picolinylidene androstane
derivatives, as a group of compounds with significant anticancer activities.
The determination of logD is practically important for estimation and
prediction of pharmacokinetic and pharmacodynamic behavior of compounds in a
living organism and it is related to blood-brain barrier permeability, skin
permeability, gastrointestinal absorption, binding to plasma proteins, etc.
These features are crucial for the determination of potential drug
candidates as well. The results presented in this study include
determination of pH versus logD profiles, pH versus molecular charge
profiles and determination of isoelectric point of eleven 17?- picolyl
androstane derivatives and thirteen 17(E)-picolinylidene androstane
derivatives. Since the pH of the organism differs depending on the organ
(for example, the pH of the blood is significantly different from the pH of
the stomach), these profiles are significant because they indicate in what
form the molecule will exist and how it will be distributed between
different phases at certain pH value. The influence of tautomerization and
resonance was taken into account during the modeling of logD parameters.
Eventually, the correlations between logD values and specific absorption,
distribution, metabolism, and excretion (ADME) properties, such as human
intestinal absorption (HIA) and permeability of heterogeneous human
epithelial colorectal adenocarcinoma cells (Caco-2), were determined.

Published: December 2019

Increasing fossil fuel depletion that leads to air pollution and global
warming have become serious environmental problem. For this reason, a
numerous of alternative biofuels have been developed and investigated as
potential energy sources to substitute them. One of promising and highly
effective technology for conversion of wet and waste biomass into
multi-functional materials is a hydrothermal carbonization. In this study
grape pomace was hydrothermally carbonized at different temperatures (180,
200 and 220?C). Produced hydrochars were characterized in order to
investigate its potential application as an alternative and energy-efficient
renewable fuels. The carbon, fixed carbon, sulphur and volatile matter
contents were determined in all hydrochar samples. Obtained results showed
that temperatures play significant role on the structural characteristics of
produced materials. As expected, the carbon content and fixed carbon content
in hydrochars were increased with temperature increasing. Higher yields of
carbon and fixed carbon observed in hydrochars indicated that intensive
carbonization of biomass occurred. On the contrary, sulphur and volatile
matter content were decreased. Observed reduction may be a result of
dehydration and decarboxylation of grape pomace during hydrothermal
treatment. These reductions are highly beneficial and improve the efficiency
of solids? direct combustion. Decreased volatile matter content can
potentially reduce the release of inorganic vapours and pollutant emission
during combustion, while decreased sulphur content preventing generation and
emission of harmful sulphur oxides, SOx, compared to the parent biomass. The
present study showed that hydrothermal carbonization mproved fuel qualities
and potential of grape pomace hydrochars among different reaction
temperatures.

In the present work, an in-house centrifugal casting setup was developed in
the laboratory. Waste natural fillers such as soap nuts seeds, Aegle
marmelos, and Terminalia chebula were used for the preparation of polyester
based composite by using centrifugal casting technique. The influence of
filler loading (3%, 6%, 9% and 12% by weight) on the physical-mechanical
behaviour of hybrid composites has been performed. The moisture absorption
tests were conducted according to the ASTM D 570-98 standards. Hybrid
composites with varying composition of polyester, Aegle marmelos, Terminalia
chebula, and soap nut seed were fabricated. It has been observed that the
maximum water absorption was in the range of 0.23% to 2.12% (weight
fraction), the maximum tensile strength 47.83 MPa, hardness 71VH and impact
strength 5.8 Joule for the hybrid composite material with 12 wt% Aegle
marmelos, 9 wt% Terminalia chebula, 6 wt% soap nuts seed. The minimum
specific wear rate (0.00196 mm3/Nm) was obtained for the composition of 12
wt% soap nuts seed and 3 wt% Aegle marmelos.
Adsorption of Cu(II) ions from synthetic solution by sunflower seed husks

Published: December 2019

Annual production of the sunflower seed in Serbia is between 650,000-720,000
tons. Most of this amount is used in vegetable oil industry. Abundant
by-products from this processing are sunflower seed husks. Husks are usually
incinerated by vegetable oil producers in order to obtain energy, used as an
animal feed, or, unfortunately, landed up at some landfills. In order to
promote new, added value for this abundant, renewable resource, the
investigation presented in this paper was conducted. For that purpose,
adsorption of Cu(II) ions from synthetic solution by unmodified sunflower
seed husks was examined. ATR-FTIR was used to identify functional groups as
potential active sites for Cu(II) sorption. Zeta potential values were
determined to reveal the surface charge, while the cation exchange capacity
(CEC) was determined to reveal the amount of exchangeable ions on its
surface. ATR-FTIR analysis revealed the presence of specific functional
groups (hydroxyl, carboxyl, carbonyl, and amine) responsible for removal of
Cu(II) ions. The total CEC of sunflower husk is 47.74 meq/100g and Ca(II)
and Mg(II) ions are in dominant exchangeable positions. The study of
ion-exchange mechanism involvement was done and results confirmed that this
mechanism is not the only mechanism which is involved in copper sorption.
Also, the results show that the Cu(II) ions have preference for Mg(II) ions
substitution. Sorption experiments were conducted in batch system. The
effect of operating parameters (pH, contact time, initial concentration of
Cu(II) ions and adsorbent dosage) on the adsorption capacity were
investigated. The obtained experimental data were fitted by Langmuir and
Freundlich isotherm models. The maximum adsorption capacity for Cu(II) ions
calculated from Langmuir adsorption isotherm was 34.89 mg/g which is 15 to
35% higher than the capacity that other researchers reported previously for
the same material and pollutant. These results are suggesting that sunflower
seed husks have a potential to be applied as an effective adsorbent of
copper ions from contaminated waters.
Levels and risk assessment of selected persistent organic compounds in dust samples from Tianjin, China
Authors: Skrbic Biljana , Antic Igor , Yaqin Ji
Published: December 2019

The aim of this paper was to determine spatial variation of 6 indicator
polychlorinated biphenyls (PCBs) and 18 organochlorine pesticides (OCPs) in
street dust samples (n=49) collected during summer season from
suburban/urban zones of Tianjin, China. Sample preparation was performed by
using accelerated solvent extraction with simultaneous extraction and
clean-up of PCBs and OCPs, while quantification was carried out using gas
chromatography coupled with microelectro absorption detector and gas
chromatography coupled with mass spectrometry. The total concentrations of
studied PCBs varied from <method limit of quantification (MLOQ) (0.028) to
6.38 ng/g (mean 0.72 ng/g and the median value of 0.028 ng/g), while the
total concentrations of studied OCPs varied from <MLOQ (0.020) to 123 ng/g
(mean 33.6 ng/g and the median value of 25.9 ng/g). Regarding the OCPs
analyzed, dichlorodiphenyltrichloroethanes (DDTs),
beta-hexachlorocyclohexane (?-HCH), and ?-HCH were quantified, while all
indicator PCBs were quantified at least in one sample, with the exception of
PCB 180. Additional, principal component analysis was performed to evaluate
relationships between quantified compounds (PCBs, DDTs, and HCHs) and dust
characteristics. No correlation was found among quantified compounds and
dust characteristics with the exception of PCB 101 and PCB 138, which
correlates positively with pH and negatively with conductivity. The total
lifetime carcinogenic risk (TLCR) as well as total non-carcinogenic risk
hazard quotient (TnHQ) indicated that the risk to the human population
related to the presence of OCPs and PCBs in dust samples was acceptable.

Published: December 2019

The powder flow plays an important role in the manufacture of dosage form
such as direct compression tablets. The objective of this research was to
investigate the individual and interaction effects of magnesium stearate
(MgSt) (Merck Ltd., Germany) as lubricant and sodium starch glycolate (SSG)
(Primojel?) as superdesintegrator on powder flowability. Powder formulations
were prepared by mixing different concentration of MgSt (0.25% and 5%) and
SSG (0.5% and 4%) with microcrystalline cellulose (MCC) (Vivapur?101) or
spray-dried lactose (LAC) (Super Tab 21AN) as diluents. Eight powder
formulations were prepared using as filler LAC and MCC, as
superdesintegrator SSG and as lubricant MgSt in ratios as follows: P1 (LAC :
0.5% SSG : 0.25% MgSt); P2 (LAC : 4% SSG : 5% MgSt); P3 (LAC : 0.5% SSG : 5%
MgSt); P4 (LAC : 4% SSG : 5% MgSt); P5 (MCC : 0.5% SSG : 0.25% MgSt); P6
(MCC : 4% SSG : 5% MgSt); P7 (MCC : 0.5% SSG : 5% MgSt); P8 (MCC : 4% SSG :
0.25% MgSt). The powder formulations were evaluated using indirect methods
of flowability evaluation according to 9th European Pharmacopoeia:
measurement of tapped and bulk density (Ph.Eur.9, 2.9.34) and angle of
repose (Ph.Eur. 2.9.36). Also, compressibility index, Hausner?s ratio were
calculated. A full factorial design with three factors at two levels and
response surface methodology were applied to evaluate the influence of
various concentrations of MgSt and SSG on powder flowability. The results
indicate that flow properties improved with decrease of SSG content and with
increase of MgSt content. Magnesium stearate in powder formulations with
microcrystalline cellulose has a greater influence on the improvement of the
flow properties than powder formulations with spray-dried lactose.
An inquiry into the girls school at Serbian Queen Helen’s court
Authors: Todic Branislav
Published: December 2019

Archbishop Daniel II wrote The Life of Queen Helen about ten years after the
death of this Serbian queen (1314), wife to King Uros I. It is a work of
complex structure which features a harmonious intertwining of information
from the biography of queen and nun Helen with an extensive exposition of
the author. The work depicts the Queen?s early commencement of good deeds:
she fed the poor, clothed the naked, hosted the homeless and richly donated
to churches and priests. ?She was not pleased only with this,? says the Life
at a later place, ?but she also added another virtue to that; she ordered
that in all of her lands the daughters of poor parents should be assembled,
and feeding them at her court, she brought them up in all good manners and
handiwork befitting the female sex.? This place drew critical attention very
early on, having been interpreted as the foundation of the first girls
school in Serbia, and it remains the most popular part of the Life until the
present day. However, that passage can only be found in one copy of the Life
of Queen Helen - the most recent one, from 1780 (The Library of the Serbian
Patriarchate in Belgrade, Cod. 51). That circumstance, as well as the fact
that the quoted passage contains words not used by Archbishop Daniel II, may
lead us to a conclusion that it is actually an interpolation into the Life?s
original text. The story of a girls school at Queen Helen court was taken
from Zaharija Orfelin?s book The History of Peter the Great, printed in
1772, which copiously described Tsarina Catherine II?s merits in educating
female and poor children in Russia. The information from Orfelin?s book was
transposed and adapted to the style of Daniel II?s text, and the
characteristics of the enlightened Russian Tsarina were projected onto the
person of Serbian Queen Helen. That was done very skilfully, due to which
this interpolation in The Life of Queen Helen has so far been undetected.

The shorter version of the apocryph the history of Aphroditian the Persian
Authors: Jovanovic Tomislav
Published: December 2019

This paper deals with the apocryph known as The History or The Narrative of
Aphroditian the Persian. The topic of his narrative is the coming of the
Magi from the East to Bethlehem in order to announce the birth of Christ.
Their journey is marked by the miraculous guidance they receive from a star
pointing their way. The motives of the journey of the Magi are contained in
Chapter Two of the Gospel According to Matthew. The longer variant of the
apocryph contains elements of the biblical basis to a considerable degree.
In addition to this, it also contains polemical parts about faith
originating from the court of the Persian King Arenat, featuring the
participation of Christians, heretics and Jews. Aphroditian, as the High
Priest and the King?s adviser, was entrusted with the task of deciding on
the outcome of their debate. In doing so, he was partial to the Christian
participants. A critical view of the apocryph on Aphroditian was expressed
by Maximus the Greek in a separate text. This apocryph is known in Serbian
copies in two variants, the longer and the shorter one. For the purpose of
analysis within this paper, we have used two copies of the shorter version,
dating from the 16th and the 17th century respectively; the first one is
from the collection of the Archive of the Serbian Academy of Sciences and
Arts no. 428, whereas the other is from the Library of the Patriarchate in
Belgrade, signature no. 343. In the addendum, we enclose the text of the
apocryph.

exogenous factors: environ¬mental set-up, housing conditions,
education, public services, social security, protection of people, etc.
Health improvement and the creation of potentials for good health
before health problems and vulner¬ability appear are the fundamental
determinants of health promotion.

The
World Health Organization advocates health promotion and providing
healthy surroundings that would allow the maximal expression of all
human potentials (mental, physical, social, spiritual). The aim of
this article was to examine the association of environmental factors
that affect mental and physical health. By a series of public health
pro¬grams, there is an attempt to preserve health from the earliest
beginning of life – from its conceivement. Negative environmental
factors present in the early phases of childhood may produce
far-reaching consequences for the entire life. Critical groups include
elderly people, homeless, migrants, persons with special needs and
those living on the margin of poverty.

The
reorientation of the health system is necessary, so that its focus is
moved toward the individual and community, and to strengthen the
culture oriented to health and prevention, not to disease. The
coop¬eration and linking inside the sector and with other sectors by
the creation of partnerships and networks is unavoidable. There are
many examples of the Healthy Cities project that contributed to the
wellbeing of citizens on the level of city administration.

Authors: Belovas Igoris
Published: December 2019

We consider the absolute values of the Selberg zeta-function, associated to the compact Riemann surface, at places symmetric with respect to the line ℛ(s) = 1/2. We prove an inequality for the Selberg zeta-function, extending the result of R. Garunkštis and A. Grigutis.

Authors: Bilal S. , Cârjă O. , Donchev T. , Javaid N. , Lazu A. I.
Published: December 2019

We show here that the set of the integral solutions of a nonlocal differential inclusion is dense in the set of the solution set of the corresponding relaxed differential inclusion. We further define a notion of limit solution and show that the set of limit solutions is closed and is the closure of the set of integral solutions. An illustrative example is provided.
Depth and Stanley depth of the edge ideals of the powers of paths and cycles
Authors: Iqbal Zahid , Ishaq Muhammad
Published: December 2019

Let k be a positive integer. We compute depth and Stanley depth of the quotient ring of the edge ideal associated to the kth
power of a path on n vertices. We show that both depth and Stanley depth have the same values and can be given in terms of k and n. If n≣0, k + 1, k + 2, . . . , 2k(mod(2k + 1)), then we give values of depth and Stanley depth of the quotient ring of the edge ideal associated to the kth
power of a cycle on n vertices and tight bounds otherwise, in terms of n and k. We also compute lower bounds for the Stanley depth of the edge ideals associated to the kth
power of a path and a cycle and prove a conjecture of Herzog for these ideals.

Monitoring of selected fertilizer nutrients in surface waters and soils of agricultural land in the river valley in Central Poland
Authors: Burzyńska Irena
Published: December 2019

The aim of the study was to assess the content of soluble forms of fertilizer nutrients (N, P, K) in the cultivated soil layer up to 20 cm deep from agricultural land in the river valley, and the concentration of these nutrients in the surface waters of the Raszynka River.

In the years 2016–2017, the surface water samples from the Raszynka Rriver (17 points) and soil (19 points) were collected from agricultural areas near the Raszynka River.

The surface water samples were collected once a month during the March–October 2016–2017. The contents of nitrogen (Ntot, NO3-N and NH4-N), phosphorus (Ptot, PO4-P), total organic carbon (TOC and K and Ca) in soils and in waters were determined in the sample solutions.

It was shown that river water was of low quality due to the high concentration of nitrogen and phosphorus and electrical conductivity (EC). The most polluted were the waters of the lower section of the river located in the vicinity of arable land and agricultural built-up areas. The soluble forms of nutrients content in the cultivated soil layer was varied depending on the kind of nutrient, way of agricultural land use, and the term of soil sampling. The content of dissolved P forms in the soil was the highest in autumn on arable lands after harvesting of vegetables (GO-W: 10.24 mg Ptot·kg−1 in D.M.) and this component may migrate with surface runoff and increase the risk of surface water eutrophication.
Hydrological modeling using the SWAT model based on two types of data from the watershed of Beni Haroun dam, Algeria
Authors: Kateb Zakaria , Bouchelkia Hamid , Benmansour Abdelhalim , Belarbi Fadila
Published: December 2019

The dam of Beni Haroun is the largest in Algeria, and its transfer structures feed seven provinces (wilayas) in the eastern part of Algeria. Due to its importance in the region, it has now become urgent to study its watershed as well as all the parameters that can influence the water and solid intakes that come into the dam. The Soil and Water Assessment Tool (SWAT) model is used to quantify the water yields and identify the vulnerable spots using two scenarios. The first one uses worldwide data (GlobCover and HWSD), and the second one employs remote sensing and digital soil mapping in order to determine the most suitable data to obtain the best results. The SWAT model can be used to reproduce the hydrological cycle within the watershed. Concerning the first scenario, during the calibration period, R2 was found between 0.45 and 0.69, and the Nash–Sutcliffe efficiency (NSE) coefficient was within the interval from 0.63 to 0.80; in the validation period, R2 lied between 0.47 and 0.59, and the NSE coefficient ranged from 0.58 to 0.64. As for the second scenario, during the calibration period, R2 was between 0.60 and 0.66, and the NSE coefficient was between 0.55 and 0.75; however, during the validation period, R2 was in the interval from 0.56 to 0.70, and the NSE coefficient within the range 0.64–0.70. These findings indicate that the data obtained using remote sensing and digital soil mapping provide a better representation of the watershed and give a better hydrological modelling.
Impact study of Beni-Haroun dam on the environmental and socio-economic elements in Kébir-Rhumel basin, Algeria
Authors: Marouf Nadir , Remini Boualem
Published: December 2019

Surface water of Kébir Rhumel basin is indispensable for domestic and industrial needs of this region. Industrial development, with water excessive use and chemical products, in production and industrial treatment, and not sustainable fertilizers in agriculture, constitutes a serious threat to maintain our resources of good water quality. The majority of domestic and industrial wastewaters of the region, discharged to the stream water of Kébir Rhumel basin, promote the water enrichment in nutritious elements, phosphorus and nitrogen and particularly, the resulting increase in the aquatic primary production, mainly the planktonic or benthic algae. As a result, the physical and chemical properties of water deteriorate.

This basin allows construction of the largest dam in Algeria “Beni-Haroun dam”. The infrastructure that was one of the greatest challenges of Algeria is now a reality. Hydraulic complex of Beni-Haroun remains a strategic and major achievement in the development program of water resources sector. This enormous building was constructed in the territory of the Wilaya (province) of Mila, used to meet water needs, with four million inhabitants, of eastern Algeria and other neighbouring regions that have suffered from lack of water consumption, especially in summer. In addition, it will irrigate over 42 000 ha, going thus to the several plains.

Integration of sociological and environmental concerns into dams design is a recent phenomenon. It is considered at the impact study level, during which the dam study project is accompanied by a survey to assess project impact on natural environment and socioeconomic development.
Decision-making models using the Analytical Hierarchy Process in the urgency of land consolidation works
Authors: Oleniacz Grzegorz , Skrzypczak Izabela , Leń Przemysław
Published: December 2019

Poland is characterized by a number of factors which adversely affect the agricultural economy, so this paper will aim to present the possibilities of using multi-criteria decision-making methods of Analytical Hierarchy Process (AHP) in the analysis of the spatial structure of rural areas. AHP is a widely used tool for making complex decisions based on a large number of criteria, such as, for example, land consolidation works on fragmented agricultural land. The first step is to formulate the decision-making process, then the assessment criteria and the solution variants guided by expert knowledge are determined.

A ranking, according to which the order of land consolidation and land exchange works in the studied area should be determined, will be defined by using decision-making models of the AHP method. The basis for calculations will be the weights received for the factors/parameters defined for the five thematic groups. Calculations for individual villages will be made, and then the obtained results will allow creating a ranking for the studied commune, allowing for the effective (in terms of economic and socio-economic) spending of funds for this purpose. The presented method can be successfully used to conduct analogous analyses for any area.
A comparative study of fuzzy logic-based models for groundwater quality evaluation based on irrigation indices
Authors: Vadiati Meysam , Nalley Deasy , Adamowski Jan , Nakhaei Mohammad , Asghari-Moghaddam Asghar
Published: December 2019

Groundwater quality modelling plays an important role in water resources management decision making processes. Accordingly, models must be developed to account for the uncertainty inherent in the modelling process, from the sample measurement stage through to the data interpretation stages. Artificial intelligence models, particularly fuzzy inference systems (FIS), have been shown to be effective in groundwater quality evaluation for complex aquifers. In the current study, fuzzy set theory is applied to groundwater-quality related decision-making in an agricultural production context; the Mamdani, Sugeno, and Larsen fuzzy logic-based models (MFL, SFL, and LFL, respectively) are used to develop a series of new, generalized, rule-based fuzzy models for water quality evaluation using widely accepted irrigation indices and hydrological data from the Sarab Plain, Iran. Rather than drawing upon physiochemical groundwater quality parameters, the present research employs widely accepted agricultural indices (e.g., irrigation criteria) when developing the MFL, SFL and LFL groundwater quality models. These newly-developed models, generated significantly more consistent results than the United States Soil Laboratory (USSL) diagram, addressed the inherent uncertainty in threshold data, and were effective in assessing groundwater quality for agricultural uses. The SFL model is recommended as it outperforms both MFL and LFL in terms of accuracy when assessing groundwater quality using irrigation indices.
Shaping cross-sectoral cooperation based on smart specializations in the city of Zielona Góra
Authors: Gębska Karolina
Published: December 2019

Among a big number of forms of relations, which the collaboration of a minimum of two entities may be based on, it is important in the context of the science and business environment to find a reference point connecting these entities. If it is necessary to integrate two sectors, this process is complex. The solution to this problem is to find a common point of reference. On the example of strengthening the ties between business and science sectors, the merging function is adopted by selected smart specializations in the European, national and regional areas. This article uses the example of Zielona Góra, analysing the smart specializations of the Lubuskie voivodship and the research group specifying entrepreneurs and scientists performing their activities in this city the potential of permanent relationship was assessed, which may become the basis for identifying barriers and opportunities in the context of building a lasting relationship.
