Biconjugate residual algorithm for solving general Sylvester-transpose matrix equations
Authors: Hajarian Masoud
Published: April 2019

The present paper is concerned with the solution of the coupled generalized
Sylvester-transpose matrix equations {A1XB1 + C1XD1 + E1XTF1 = M1, A2XB2 +
C2XD2 + E2XTF2 = M2, including the well-known Lyapunov and Sylvester matrix
equations. Based on a variant of biconjugate residual (BCR) algorithm, we
construct and analyze an efficient algorithm to find the (least Frobenius
norm) solution of the general Sylvester-transpose matrix equations within a
finite number of iterations in the absence of round-off errors. Two numerical
examples are given to examine the performance of the constructed algorithm.
A characterization of unbounded generalized meromorphic operators
Authors: Berkani Mohamed , Boudhief Monia , Moalla Nedra
Published: April 2019

In this paper, we study the class of unbounded generalized meromorphic
operators GM(E,?), where E is a finite subset of C, which generalizes the
notion of unbounded meromorphic operators. More precisely, we give a
decomposition and some characterizing properties of these operators based on
the punctured neighborhood theorem and the operational calculus for
unbounded operators.
Weak Markov operators
Authors: Duru Hūlya , Ilter Serkan
Published: April 2019

Let A and B be f -algebras with unit elements eA and eB respectively. A
positive operator T from A to B satisfying T(eA) = eB is called a Markov
operator. In this definition we replace unit elements with weak order units
and, in this case, call T to be a weak Markov operator. In this paper, we
characterize extreme points of the weak Markov operators.
On dimension andweight of a local contact algebra
Authors: Dimov G. , Ivanova-Dimova E. , Düntsch I.
Published: April 2019

As proved in [16], there exists a duality ?t between the category HLC of
locally compact Hausdorff spaces and continuous maps, and the category DHLC
of complete local contact algebras and appropriate morphisms between them.
In this paper, we introduce the notions of weight wa and of dimension dima
of a local contact algebra, and we prove that if X is a locally compact
Hausdorff space then w(X) = wa(?t(X)), and if, in addition, X is normal, then
dim(X) = dima(?t(X)).
On the circulant matrices with Ducci sequences and Fibonacci numbers
Authors: Solak Süleyman , Bahşi Mustafa , Kan Osman
Published: April 2019

A Ducci sequence generated by A = (a1,a2,...,an)? Zn is the sequence
{A,DA,D2A,...} where the Ducci map D : Zn ? Zn is defined by D(A) = D(a1,
a2,...,an) = (|a2-a1|, |a3-a2|,..., |an-an-1|, |an-a1|).
In this study, we examine some properties of the matrices Cn, DCn, D2Cn;
where Cn =Circ(c0,c1,..., cn-1) is a circulant matrix whose entries
consist of Fibonacci numbers.

Published: April 2019

In this work, we generalize the concepts of statistically convergent sequence
of order ? and statistical Cauchy sequence of order ? by using the

Analysis of Keller-Segel model with Atangana-Baleanu fractional derivative
Authors: Dokuyucu Mustafa , Baleanu Dumitru , Çelik Ercan
Published: April 2019

The new definition of the fractional derivative was defined by Atangana and
Baleanu in 2016. They used the generalized Mittag-Leffer function with the
non-singular and non-local kernel. Further, their version provides all
properties of fractional derivatives. Our aim is to analyse the Keller-Segel
model with Caputo and Atangana-Baleanu fractional derivative in Caputo
sense. Using fixed point theory, we first show the existence of coupled
solutions. We then examine the uniqueness of these solutions. Finally, we
compare our results numerically by modifying our model according to both
definitions, andwedemonstrate these results on the graphs in detail. All
computations were done using Mathematica.
Convergence theorems of a faster iteration process including multivalued mappings with analytical and numerical examples
Authors: Gunduz Birol , Alagoz Osman , Akbulut Sezgin
Published: April 2019

In this paper, we first give the modified version of the iteration process
of Thakur et al. [15] which is faster than Picard, Mann, Ishikawa, Noor,
Agarwal et al. [2] and Abbas et al. [1] processes. Secondly, we prove weak
and strong convergence theorems of this iteration process for multivalued
quasi nonexpansive mappings in uniformly convex Banach spaces. Thirdly, we
support our theorems with analytical examples. Finally, we compare rates of
convergence for multivalued version of iteration processes mentioned above
via a numerical example.

Authors: Alijani Azadeh
Published: April 2019

Theory of frame has been extended from Hilbert spaces to various spaces,
specially, to Hilbert C*-modules. The paper introduces operator duals for
frames with C*-valued bounds in Hilbert C*-modules. It is shown that
operator duals for frames (*-frames) share several useful properties with
ordinary duals. Some operator duals are constructed by a given operator dual
or a given *-frame. Also, a characterization of all of operator duals for a
given *-frame is obtained. Moreover, dilations of frames and their operator
duals are studied. And, an application for frames and operator duals is
suggested.

Consider a continuous time process {Yt=ZNt, t ? 0}, where {Zn} is a
supercritical Galton-Watson process and {Nt} is a renewal process which is

large deviations of the Lotka-Negaev estimator of offspring mean.
Transformation of circular random variables based on circular distribution functions
Authors: Mojtaba Hatami , Hossein Alamatsaz
Published: April 2019

In this paper, we propose a new transformation of circular random variables
based on circular distribution functions, which we shall call inverse
distribution function (id f ) transformation. We show that M?bius
transformation is a special case of our id f transformation. Very general
results are provided for the properties of the proposed family of id f
transformations, including their trigonometric moments, maximum entropy,
random variate generation, finite mixture and modality properties. In
particular, we shall focus our attention on a subfamily of the general
family when id f transformation is based on the cardioid circular
distribution function. Modality and shape properties are investigated for
this subfamily. In addition, we obtain further statistical properties for
the resulting distribution by applying the id f transformation to a random
variable following a von Mises distribution. In fact, we shall introduce the
Cardioid-von Mises (CvM) distribution and estimate its parameters by the
maximum likelihood method. Finally, an application of CvM family and its
inferential methods are illustrated using a real data set containing times
of gun crimes in Pittsburgh, Pennsylvania.

Published: April 2019

In the first part of this note we show that if X is a paracompact Hausdorff
space and there is a locally compact closed subspace Y of X such that for
every x ? X \ Y there exists an open neighborhood Ox of x in X such that O?x
is base-paracompact, then the space X is base-paracompact. In the second
part of this note we introduced notions of monotonically base-paracompact
(base-metacompact, base-Lindel?f) and discuss some of their properties.
On filters in BZ-algebras
Authors: Romano Daniel
Published: April 2019

The concept of weak BCC algebra (shortly: BZ-algebra) is a much-researched
logic-algebraic entity. Observing and analyzing the substructures of this
algebraic structure is important since some of them can be related to the
congruences in such algebras. In this article we introduce and discuss the
concept of BZ-filters in BZ-algebras in a slightly different way than is
present in the literature. Also, we establish connection between BZ-ideals
and BZ-filters. In addition, we consider several additional conditions
imposed on BZ-filters and establish links between them.
Hyperconnectedness modulo an ideal
Authors: Tyagi B.K. , Bhardwaj Manoj , Singh Sumit
Published: April 2019

In this paper, hyperconnectedness with respect to an ideal, called
hyperconnectedness modulo an ideal, of a topological space X is introduced.
It is shown that hyperconnectedness and hyperconnectedness modulo an ideal
coincide in case of trivial and codense ideal. Several characterisations of
hyperconnectedness modulo an ideal I are obtained using semi-open, pre-open
and semi-preopen sets. It is also shown that I-hyperconnectedness and
hyperconnectedness modulo I, where I is an ideal in a space X, are
equivalent. A new type of semi-open modulo ideal sets are defined and
several characterisations of hyperconnectedness modulo an ideal using these
sets are obtained.

of generalized Sherman-Morrison-Woodbury formula under weaker restrictions.
T-stability of the Euler method for impulsive stochastic differential equations driven by fractional Brownian motion
Authors: Yu Hui
Published: April 2019

Due to the fact that a fractional Brownian motion (fBm) with the Hurst
parameter H ? (0,1/2) U(1/2, 1) is neither a semimartingale nor a Markov
process, relatively little is studied about the T-stability for impulsive
stochastic differential equations (ISDEs) with fBm. Here, for such linear
equations with H ? (1/3, 1/2), by means of the average stability function,
sufficient conditions of the T-stability are presented to their numerical
solutionswhich are established fromthe Euler-Maruyama method with variable
step-size. Moreover, some numerical examples are presented to support the
theoretical results.
An extension of Pochhammer’s symbol and its application to hypergeometric functions, II
Authors: Masjed-Jamei Mohammad , Milovanovic Gradimir
Published: April 2019

Recently we have introduced a productive form of gamma and beta functions and
applied them for generalized hypergeometric series [Filomat, 31 (2017),
207-215]. In this paper, we define an additive form of gamma and beta
functions and study some of their general properties in order to obtain a
new extension of the Pochhammer symbol. We then apply the new symbol for
introducing two different types of generalized hypergeometric functions. In
other words, based on the defined additive beta function, we first introduce
an extension of Gauss and confluent hypergeometric series and then, based on
two additive types of the Pochhammer symbol, we introduce two extensions of
generalized hypergeometric functions of any arbitrary order. The convergence
of each series is studied separately and some illustrative examples are
given in the sequel.

mathematical tool to deal with uncertainties. In this work, we define two
new operations on the set of soft matrices, called inverse production and

cryptosystem as a new cryptosystem method by using inverse production and
characteristic production of soft matrices. We finally define soft
encryption and soft decryption. Some applications are given
Hyper BL-algebras

Published: April 2019

We put forth the concept of hyper BL-algebras which is a generalization of
BL-algebras. We give some non-trivial examples and properties of hyper
BL-algebras. Moreover, we introduce weak filters and weak deductive systems
of hyper BL-algebras and study the relationships between them. Then we state
and prove some theorems about weak filters and weak deductive systems. In
particular, we define the concept of regular compatible congruence on hyper
BL-algebras and construct the quotient structure in hyper BL-algebras.
Finally, we discuss the conditions in which a quotient hyper BL-algebra is
an MV-algebra.

Relationship between entire functions and their derivatives sharing small function except a set
Authors: Lü Feng
Published: April 2019

The paper is mainly devoted to deriving the relationship between an entire
function and its derivative when they share one small function except
possibly a set, which is related to the famous Br?ck conjecture. In
addition, two propositions of infinite products are obtained. The first one
is the growth property of a certain infinite product. The second one is the
property of entire solutions of the differential equation which concerns
infinite products.
Non-linear multi-point flux approximation in the near-well region
Authors: Dotlic Milan , Pokorni Boris , Pusic Milenko , Dimkic Milan
Published: April 2019

We consider non-linear multi-point flux approximations (MPFA) scheme for flow
simulations in a model of anisotropic porous medium that includes wells. The
hydraulic head varies logarithmically and its gradient changes rapidly in
the well vicinity. Due to this strong non-linearity of the near-well flow,
use of the MPFA scheme in the near well region results in a completely wrong
total well flux and an inaccurate hydraulic head distribution. In this
article we propose correction of the MPFA scheme. The outcome is a scheme
that is second-order accurate even in the well vicinity for anisotropic
medium. Solution obtained with this scheme respects minimum and maximum
principle, and also, it is non-oscillating.
Error estimates for certain cubature formulae
Authors: Jandrlic Davorka , Spalevic Miodrag , Tomanovic Jelena
Published: April 2019

We estimate the errors of selected cubature formulae constructed by the
product of Gauss quadrature rules. The cases of multiple and (hyper-)surface
integrals over n-dimensional cube, simplex, sphere and ball are considered.
The error estimates are obtained as the absolute value of the difference
between cubature formula constructed by the product of Gauss quadrature
rules and cubature formula constructed by the product of corresponding
Gauss-Kronrod or corresponding generalized averaged Gaussian quadrature
rules. Generalized averaged Gaussian quadrature rule ?2l+1 is (2l +
1)-point quadrature formula. It has 2l + 1 nodes and the nodes of the
corresponding Gauss rule Gl with l nodes form a subset, similar to the
situation for the (2l + 1)-point Gauss-Kronrod rule H2l+1 associated with
Gl. The advantages of bG2l+1 are that it exists also when H2l+1 does not,
and that the numerical construction of ?2l+1, based on recently proposed
effective numerical procedure, is simpler than the construction of H2l+1.

The article discusses the physical aspects and assumptions in the formulation
of the gas dynamics and thermal physics models in conditions of ?Luna -
Resource? spacecraft landing on the Moon surface. It was proposed to divide
the problem into two stages: calculation of the gas phase and determination
of trajectories and heating of particles of lunar dust. The use of the
continuum equations and not taking into account the reverse effect of
particles on gas was substantiated. The calculation results of parameters
impingement exhaust jet of spacecraft propulsion system with Moon surface
are given. It was obtained that a reverse external force is added to the
streamlined surfaces equal to 196 N, the gas temperature at the bottom of
the cargo compartment reaches 2000 K, and the calculated heat flux was 400
kW. The trajectories of the particles of lunar dust was determined and it
was found that with a size of 1 ?m the distance of their flight range was
3.5 km.

Published: April 2019

In this work the technique of modeling of optoacoustic signal initiated by
laser pulse in composites based on transparent matrix and metal
nanoparticles was proposed. It was shown that the time to achieve mechanical
equilibrium is significantly lower than the pulse duration, and pressure is
proportional to the augmentation of the nanoparticles? temperature. Testing
of the modeling technique was carried out on the example of PETN - aluminum
nanoparticles composite in two variant with and without taking into account
the temperature dependence of the composites? optical properties. Comparison
of calculated and experimental dependences of the effective absorption
coefficient on the energy density of neodymium laser with pulse duration 14
ns was made. The modeling results are in good agreement with the
experimental data only if the temperature dependence of the optical
properties is taken into account.
Investigation of the process of explosive loading of freshwater ice
Authors: Orlov Maxim
Published: April 2019

The behaviour of freshwater ice under the action of detonation products has
been studied. As objects of the study was chosen snow covered ice of medium
thickness. The ice cover of 2018 and 2017 on the Tom River was considered
in current research. The age of the ice was approximate 130 days, but the
temperature of its formation was different. In the first case (2017), the
ice formation temperature was 7.5 % lower than in the second case. The sizes
of the lanes in the snow covered ice after detonation of 4 kg of emulsion
explosive are obtained. It was established that in the second case the
diameter of the lane was 15% smaller than in the first case. The ice edge of
the lane in the snow-covered and bare ice was determined. The edge of the
needle ice, which had a stepped shape, is presented. A qualitative and
quantitative assessment of the destruction of ice under explosive loads is
given. It was found that the temperature of ice formation influenced the
process of its destruction under explosive loads.
Comparison of two neural network approaches to modeling processes in a chemical reactor
Authors: Shemyakina Tatiana , Tarkhov Dmitriy , Vasilyev Alexander , Velichko Yulia
Published: April 2019

In this paper, we conduct the comparative analysis of two neural network
approaches to the problem of constructing approximate neural network
solutions of non-linear differential equations. The first approach is
connected with building a neural network with one hidden layer by
minimization of an error functional with regeneration of test points. The
second approach is based on a new continuous analog of the shooting method.
In the first step of the second method, we apply our modification of the
corrected Euler method, and in the second and subsequent steps, we apply our
modification of the St?rmer method. We have tested our methods on a boundary
value problem for an ODE which describes the processes in the chemical
reactor. These methods allowed us to obtain simple formulas for the
approximate solution of the problem, but the problem is special because it
is highly non-linear and also has ambiguous solutions and vanishing
solutions if we change the parameter value.
Assessment of thermal conditions in Krasnoyarsk urban area with use of different satellite data and geographic information system
Authors: Matuzko Alexandra , Yakubailik Oleg
Published: April 2019

Satellite data in the thermal infrared range are a powerful source of
information for the analysis and determination of city urban area
temperature anomalies. The article presents a technique for monitoring the
land surface temperature on the basis of combination of ?Landsat 8?
satellite thermal infrared data with PlanetScope satellite constellation
high resolution data. Such combination of satellite data from several
spacecrafts increase the detalization of temperature maps to the level of
individual city blocks. Determination of the nature and boundaries of
temperature anomalies will help to understand the causes of the unfavorable
environmental situation in Krasnoyarsk, where, in addition to high
industrial emissions, their influence and atmospheric processes, leading to
the fact that impurities are delayed and concentrated over the city. The
results shows that the temperature in the places of thermal anomalies is
5?-8? higher than the average land surface temperature of the city. Based on
the results of the analysis of summer thermal multi-temporal space images,
several thermal zones of different nature were outlined on the territory
under consideration. This information can be used in planning the
development of the city, the design of new urban neighborhoods.
Homogenization and penetration effects of 1064 nm Nd:YAG solar laser and concentrated solar radiations on ex vivo chicken breast samples
Authors: Catela Miguel , Liang Dawei , Almeida Joana , Vistas Cláudia R.
Published: April 2019

To compare the penetration effect of both 1064 nm solar laser and concentrated solar radiations on biological tissue, ex vivo experiments were performed on chicken breast samples with similar incident doses. A 1064 nm Nd:YAG solar laser and a simple solar concentrator were first developed, both capable of emitting 10 W light power. Two square cross-section hollow light beam homogenizers were then designed and built, one emitting uniform monochromatic 1064 nm laser radiation and the other emitting uniform full-spectrum solar radiation, all within 24° divergence angle with about 5 W continuous-wave light power uniformly distributed in 0.36 cm2 homogenizer output area. For the same incident irradiance distribution and exposure time, and thus for similar incident dose, different light-tissue interaction effects were found. The 1064 nm solar laser radiation was less absorbed by the samples as compared to the solar radiation, resulting in a deeper 1064 nm laser radiation penetration in the tissue, revealing that wavelength was a crucial factor for light-tissue interaction research.

Radiocarbon Dates from Jar and Coffin Burials of the Cardamom Mountains Reveal a Unique Mortuary Ritual in Cambodia's Late- to Post-Angkor Period (15th–17th Centuries AD)

Published: April 2019

We present the first radiocarbon dates from previously unrecorded, secondary burials in the Cardamom Mountains, Cambodia. The mortuary ritual incorporates nautical tradeware ceramic jars and log coffins fashioned from locally harvested trees as burial containers, which were set out on exposed rock ledges at 10 sites in the eastern Cardamom Massif. The suite of 28 14C ages from 4 of these sites (Khnorng Sroal, Phnom Pel, Damnak Samdech, and Khnang Tathan) provides the first estimation of the overall time depth of the practice. The most reliable calendar date ranges from the 4 sites reveals a highland burial ritual unrelated to lowland Khmer culture that was practiced from cal AD 1395 to 1650. The time period is concurrent with the 15th century decline of Angkor as the capital of the Khmer kingdom and its demise about AD 1432, and the subsequent shift of power to new Mekong trade ports such as Phnom Penh, Udong, and Lovek. We discuss the Cardamom ritual relative to known funerary rituals of the pre- to post-Angkorian periods, and to similar exposed jar and coffin burial rituals in Mainland and Island Southeast Asia.

Bilomas represent large collections of bile, produced due to a rupture of bile ducts. Most frequently, they are located in the perihepatic tissues, rarely intrahepatic ones. Usually, bile ducts rupture is caused by trauma, spontaneous or iatrogenic, or some underlying disease. The majority of bilomas cases are treated by means of drainage procedures. In spite of advanced diagnostic techniques, sometimes they can be misinterpreted as neoplasm. We report a case of biloma that was surgically removed due to suspicion of malignancy, which was histologically examined.

Authors: Chlost Izabela
Published: April 2019

The article describes the characteristics of water circulation in the coastal Lake Gardno. The water cycle is based on water balance data calculated for the period 2003–2007 concerning hydrological years, including the components of horizontal and vertical exchange. Due to the coastal location of the lake, particular attention was paid to the share of the seawater in the lake water cycle. It was found that the inflow of sea water accounts for 10% of the total inflow, while inflow from the land accounts for 86% of the total.
Suitability of rocks and sediments from Brzeszcze and Silesia coal mines as building materials in terms of radiological hazard
Authors: Śleziak Monika , Duliński Marek
Published: April 2019

The isotope activity concentration of rocks and bottom sediments was evaluated based on the samples collected from sedimentation ponds and gangue repositories. Radium 226Ra, thorium 228Th and potassium 40K activities were measured by gamma spectrometry using high-purity germanium detector – HPGe 4020. The radiation effect resulting from the presence of natural radionuclides was estimated by radiological hazard indices such as f
1 and f
2 coefficients, radium equivalent, internal and external hazard indices and absorbed dose rate. Performed measurements and calculations have shown that the bottom sediments are most contaminated. They may pose a serious radiological hazard for present and future generations.

Published: April 2019

The fundamental objective of the military units’ logistic system during peacetime is ensuring necessary logistic support for the military personnel to properly carry out the training and instruction activities in order to fulfill the missions assigned to the military units at every hierachical level. Concurrently, the logistic system of the military units during peacetime tracks the supply of material assets for emergency situations, crisis, mobilization and war. Achieving logistic support for military units during peacetime depends on a number of principles that underpin the provision of high-quality logistic support necessary for the fulfillment of the basic mission and the fundamental objectives of each military structure.
Performance of Multiple Rank Modulation Based on SM-MIMO
Authors: Abdulhamid Mohanad , Muchai Mwaniki
Published: April 2019

A multiple rank modulation (MRM) scheme is proposed that provides better error performance, enhances the data rate and reduces the system demodulation complexity. Multiple input multiple output (MIMO) scheme is a technique that uses several antennas at the transmitter and receiver to minimize error and optimize data speed. MRM is a novel technique that borrows from spatial modulation-MIMO (SM-MIMO) scheme. The basic idea of this scheme involves the transmitter receiving a group of bits and subdividing them into two blocks; rank index block and signal modulation block. The rank index bit block is used to select the rank to be activated and the rank selected contains at least one active transmit antenna (TA). The signal modulation bit block is encoded in a given modulation scheme for transmission. It is then transmitted through the activated rank that contains at least one active TA. The transmitted encoded signal modulation bit block is received through the receive antenna and a receiver. The receiver estimates a rank index and the transmitted symbol from the signal received. The signal modulation bit block is finally decoded. This paper addresses the performance of MRM scheme based on error performance to run cellular fifth generation (5G). We perform and present simulation results of MIMO systems employing MRM scheme to generate bit error rate (BER) of this system.

Introduction Oral diseases during pregnancy are an important reason for enhanced dental care of this vulnerable population. The aim of this study was to determine the degree of oral health awareness among pregnant women and examine their oral hygiene habits, attitudes and behaviors in relation to the professional qualification.

Material and methods The study was conducted in Foča, East Sarajevo, Bijeljina and Pale (Republika Srpska, Bosnia and Herzegovina). A total of 198 respondents voluntarily filled an anonymous survey, specially created for this research.

Results In addition to toothbrush and toothpaste, 39.8% of pregnant women did not use any additional oral hygiene resources. When brushing their teeth, 60.1% of pregnant women had bleeding gums. Also, 54.1% of pregnant women visited dentist, while 34.3% did not. Obstetrician did not advise 69.7% of respondents that the should visit dentist during pregnancy. Furthermore, 80.8% of pregnant women thought that they were more susceptible to pregnancy caries, and 29.6% of them thought that caries is disease that cannot be prevented. Respondents with university education understood that minerals from the mother’s teeth were not lost during pregnancy, which was statistically significant compared to pregnant women with secondary education.

Conclusion The level of oral health awareness of pregnant women is low. It is important that all women perform regular dental examination during pregnancy, as they will receive useful information from their dentist how to prevent oral diseases.

Published: April 2019

Background:

Disorders of sex development (DSD) are known as the inborn atypical development of chromosomal, gonadal, or anatomic sex. New opportunities in counseling DSD patients have emerged with advent of the next generation DNA sequencing (NGS) techniques.

Case Presentation:

Two clinical 46, XY DSD cases having similar phenotypical features, including ambiguous genitalia, are presented in this paper. In the first patient, no causative variant was found, meanwhile, a heterozygous variant in the CHD 7 gene considered as likely-benign was identified (chr8: 61693942, rs377139749, NM_017780.3:c.2053_2058dupGCAAAA p.Lys686_Thr687insAlaLys). Neither gonadal ability to produce androgens, nor tissue androgen sensitivity was impaired, therefore leading to a decision to maintain the initially assigned male sex in this patient. In the other patient, the study revealed previously reported heterozygous missense variant in the SEMA3A gene (chr7: 83636785, rs769957117, NM_006080.2:c.А1024G:p. Met342Val) responsible for HH type 16 (OMIM 614897). As well, a novel hemizygous variant in the AR gene (chrX: 66942818, AR: NM_000044:c.G2599C:p.Val867Leu) was identified. In conjunction with the features of HH, this leads to a decision to reassign the sex of rearing to a female.

Conclusion:

NGS technique may be helpful in optimal sex assignment in DSD cases.
Determination of Microbial Properties of Freeze Dried Traditional Cheese
Authors: Büyüksırıt Bedir Tuba , Kuleaşan Hakan
Published: April 2019

The use of dried cheese in food production and food preparation sectors is becoming increasingly widespread. Dried cheese is preferred because of their longer shelf life at room temperatures, smaller packaging sizes, practical use, and their ease of homogenization in food products. Various technologies are currently being used for the drying of cheese and efforts are still being made to develop new methods. Freeze drying is a highly preferred technique for the production of dried cheese due to high quality of the final product. Instant removal of water and low process temperatures ensure an effective prevention of chemical and microbial deterioration. In this study, White, Kashar and Tulum cheeses were dried by freeze-drying method. Physicochemical analyses were carried out on the first day in order to determine the initial quality of cheese samples. The moisture and salt content were highest in White cheese, titratable acidity and fat content were highest in Tulum Cheese. Freze dried cheese samples were stored in room conditions for 6 months and changes in microbial populations such as mesophilic aerobic bacteria, yeast and moulds, lactic acid bacteria, Staphylococci spp. and coliform group bacteria were determined. The results showed that Tulum Cheese contained highest microbial counts in general. The number of bacteria was 7.71±0.10 log cfu/g in Tulum Cheese, 5.70±0.07 log cfu/g in White cheese. Total counts of yeasts and molds were 7.37±0.06 log cfu/g for Tulum cheese and 4.92±0.07 log cfu/g for Kashar Cheese. Statistical analysis was performedby using Minitab Statistical Package Program to evaluate the results of microbiological analysis on dried cheese samples.

Authors: Gil Francisco , Mendizabal Mikel , Amezqueta Ana , Aznal Elena , Durá Teodoro , Sánchez-Valverde Felix
Published: April 2019

Background: Cow milk allergy (CMA) is the most common food allergy in infants. Some patients will express, in the future, other allergic diseases (allergic march). Objective: To evaluate if a new scoring system could determine the risk of developing allergic
march. Methods: A retrospective observational cohort study of subjects who were immunoglobulin E (IgE) mediated was conducted. We defined a risk score for atopy (RSA), including clinical and laboratory variables. Three risk groups were defined according to the RSA. We defined
as dependent variables atopy (one or more allergic diseases) and atopy+ (two or more allergic diseases). A multivariate logistic regression model was created, which included RSA and the type of formula (high-grade extended hydrolyzed formula [EHF] with Lactobacillus rhamnosus GG (LGG), high-grade
EHF without LGG, and other formulas). Results: A total of 211 patients were recruited. When we analyzed the risk of atopy+, we found an increased risk for RSA intermediate-risk (odds ratio [OR 2.08] [95% confidence interval {CI}, 0.95‐4.56) and high-risk (OR 24.74
[95% CI, 6.26‐97.73]) groups, and a decreased risk for the subjects fed with high-grade EHF (OR 0.42 [95% CI, 0.20‐0.87]) and also in those subjects fed with high-grade EHF plus LGG (OR 0.30 [95% CI, 0.09‐0.98]). Conclusion: RSA is a simple and useful
tool to predict the risk of developing other allergic diseases in patients with IgE-mediated CMA.
Effect of mometasone furoate nasal spray on moderate-to-severe nasal congestion in seasonal allergic rhinitis: A responder analysis
Authors: Urdaneta Eduardo , Tunceli Kaan , Gates Davis
Published: April 2019

Background: Nasal congestion is consistently identified as the most bothersome symptom of seasonal allergic rhinitis (SAR), and, in guidelines, intranasal corticosteroids are the preferred treatment for nasal congestion. Objective: The aim of this post
hoc cumulative responder analysis was to examine the nasal congestion response in detail by depicting the level of response obtained in two double-blind, placebo controlled studies of mometasone furoate nasal spray (MFNS) therapy for SAR, conducted from August to October 2008 at U.S. sites,
in which nasal congestion was prespecified as the primary end point. Methods: Patients ≥12 years of age with a ≥2-year SAR history, positive skin test result, and moderate or severe nasal congestion were randomly assigned to once-daily treatment in the morning with
MFNS or placebo for 15 days. The primary end point was the change from baseline in morning and evening reflective nasal congestion scores averaged over days 1‐15. Treatment response, which ranged from >0% to >90% improvement, was evaluated at 10% intervals; >30% and >50%
improvements were further evaluated by using the Mietinnen-Nurminen method weighted by study to test the differences of proportions. The Breslow-Day equal odds ratios test was used to justify pooling. Results: Of the 344 and 340 patients in the MFNS and placebo groups,
respectively, the proportions of patients who experienced a >30% response in nasal congestion, averaged over 15 days, were 37% versus 19% in the MFNS and placebo groups, respectively (p < 0.001). Those who experienced a >50% response were 13% and 7%, respectively (p = 0.003). Among
the patients treated with MFNS, the mean response was greater during the second versus the first week of treatment. There was no difference between responses in the morning versus evening or for patients with moderate versus severe nasal congestion at baseline. Conclusion:
MFNS is effective in relieving moderate-to-severe nasal congestion in patients with SAR. The response to MFNS is maintained with once-daily administration and improves with continuous use over 2 weeks.
