Abstract
Salinity is one of the major abiotic stress factors limiting rice production. Glabrousness is a trait of agronomic importance in rice (Oryza sativa L.). We previously found a single-gene recessive mutant sst, which displayed increased salt tolerance and glabrous leaf and glume without trichomes, and identified an SBP-box gene OsSPL10 as the candidate of the SST gene. In this study, OsSPL10-knockout and OsSPL10-overexpression mutants were created to check the function of the gene. The knockout mutants exhibited enhanced salt tolerance and glabrous leaves and glumes as expected, while the overexpression mutants showed opposite phenotypes, in which both salt sensitivity and trichome density on leaf and glume were increased. These results clearly confirmed that OsSPL10 is SST, and suggested that OsSPL10 controls the initiation rather than the elongation of trichomes. In addition, expression analysis indicated that OsSPL10 was preferentially expressed in young panicle and stem, and protein OsSPL10 was localized in nucleus. Taken together, OsSPL10 negatively controls salt tolerance but positively controls trichome formation in rice.

En este ensayo sobre Psicología de la Educación, propongo distinguir entre el quehacer educativo centrado en la relación instrucción-evaluación, el cual, siguiendo al Barthes estructuralista, entiendo como una Educación basada en la verosimilitud crítica, por oposición a un quehacer educativo que intentando recobrar todas las posibilidades del lenguaje, es entendida como literalización, es decir, como la recuperación por parte de los sujetos educativos de un logos que la instrucción-evaluación educativa les ha escamoteado.

En la actualidad, el gerente educativo, o director, dispone de una serie de herramientas de la administración moderna que permiten guiar la institución educativa hacia la calidad. Para ello, debe cumplir con una serie de funciones que se enmarcan dentro del proceso administrativo, tales como: planear, organizar, dirigir y controlar las actividades del centro a educativo. Este escrito tiene como objetivo dar a conocer algunos de estos aportes y la manera en que el gerente educativo puede utilizarlos para mejorar la institución educativa. La administración moderna pone a disposición de éste diferentes concepciones, que ayudan a visualizar la forma en que se debe gerenciar la institución.
La principal conclusión que se extrae es que no existe un cuerpo teórico único que garantice el éxito a un gerente educativo, sino que se debe utilizar lo mejor
de cada una de las concepciones que aporta la administración moderna, y adaptarlas, de acuerdo con las circunstancias.
Statistical Classification of the Observation of Nuggetless Spatial Gaussian Process with Unknown Sill Parameter
Authors: Dučinskas K. 
Published: October 2019

The problem of classification of spatial Gaussian process observation into one of two populations specified by different regression mean models and common stationary covariance with unknown sill parameter is considered. Unknown parameters are estimated from training sample and these estimators are plugged in the Bayes discriminant function. The asymptotic expansion of the expected error rate associated with Bayes plug-in discriminant function is derived. Numerical analysis of the accuracy of approximation based on derived asymptotic expansion in the small training sample case is carried out. Comparison of two spatial sampling designs based on values of this approximation is done.
Oscillation of Non-Linear Systems Close to Equilibrium Position in the Presence of Coarse-Graining in Time and Space
Authors: Jumarie G. 
Published: October 2019

One considers the motion of nonlinear systems close to their equilibrium positions in the presence of coarse-graining in time on the one hand, and coarse-graining in time on the other hand. By considering a coarse-grained time as a time in which the increment is not dt but rather (dt)c > dt, one is led to introduce a modeling in terms of fractional derivative with respect to time; and likewise for coarse-graining with respect to the space variable x. After a few prerequisites on fractional calculus via modified Riemann-Liouville derivative, one examines in a detailed way the solutions of fractional linear differential equations in this framework, and then one uses this result in the linearization of nonlinear systems close to their equilibrium positions.
Unsteady Oscillatory Flow and Heat Transfer in a Horizontal Composite Porous Medium Channel
Authors: Umavathi J. C. C. , Chamkha A. J. J. , Mateen A. , Al-Mudhaf A. 
Published: October 2019

The problem of unsteady oscillatory flow and heat transfer in a horizontal composite porous medium is performed. The flow is modeled using the Darcy-Brinkman equation. The viscous and Darcian dissipation terms are also included in the energy equation. The partial differential equations governing the flow and heat transfer are solved analytically using two-term harmonic and non-harmonic functions in both regions of the channel. Effect of the physical parameters such as the porous medium parameter, ratio of viscosity, oscillation amplitude, conductivity ratio, Prandtl number and the Eckert number on the velocity and/or temperature fields are shown graphically. It is observed that both the velocity and temperature fields in the channel decrease as either of the porous medium parameter or the viscosity ratio increases while they increase with increases in the oscillation amplitude. Also, increasing the thermal conductivity ratio is found to suppress the temperature in both regions of the channel. The effects of the Prandtl and Eckert numbers are found to decrease the thermal state in the channel as well.
Stability and Hopf-Bifurcation Analysis of Delayed BAM Neural Network under Dynamic Thresholds
Authors: Gupta P. D. D. , Majee N. C. C. , Roy A. B. B. 
Published: October 2019

In this paper the dynamics of a three neuron model with self-connection and distributed delay under dynamical threshold is investigated. With the help of topological degree theory and Homotopy invariance principle existence and uniqueness of equilibrium point are established. The conditions for which the Hopf-bifurcation occurs at the equilibrium are obtained for the weak kernel of the distributed delay. The direction and stability of the bifurcating periodic solutions are determined by the normal form theory and central manifold theorem. Lastly global bifurcation aspect of such periodic solutions is studied. Some numerical simulations for justifying the theoretical analysis are also presented.
COMPARISON OF LATERALIZATION THYROPLASTY AND LASER CORD WEDGE RESECTION IN TERMS OF VOICE QUALITY IN PATIENTS WITH BILATERAL ABDUCTOR VOCAL CORD PARALYSIS
Authors: TUZUN Dursun , SUOGLU Yusufhan , GOZELER Mustafa Sitki 
Published: October 2019

AbstractBackground/Aims: It was aimed to compare
lateralization thyroplasty with laser cord wedge resection in terms of
postoperative voice analysis, duration of hospital stay, tracheotomy rate, and
decannulation time in patients with
bilateral abductor vocal cord paralysis. Methods: A
total of 37 patients who presented to our department with bilateral abductor
vocal cord paralysis between February 2005 and February 2009 were enrolled in
this prospective study. External
arytenoid lateralization (lateralization thyroplasty) was randomly performed in
22 patients and laser posterior cordotomy was performed in 15 patients. Fifteen
healthy volunteers were assigned to the control group. Postoperative 6th
month maximum phonation time (MPT), S/Z ratio, and the results of objective
voice analysis [mean frequency perturbation (jitter), mean amplitude
perturbation (shimmer), mean fundamental frequency (fo), and NHR (noise to
harmonic ratio)] were compared between the two groups and the control group.
Decannulation time, patient tracheotomy status, and duration of hospital stay
were also recorded.Results: The mean
postoperative MPT decreased but S/Z ratio increased in both patient groups
compared to the control group. The mean MPT was shorter in the external
arytenoid lateralization group versus the laser posterior cordotomy group (p= 0.011).
There was no statistically significant difference between the external
arytenoid lateralization and laser posterior cordotomy groups in terms of mean
S/Z ratio (p= 0.306). It was observed that jitter, shimmer, and NHR values were
increased, i.e. voice quality impaired, in both patient groups. Jitter (p= 0.004),
shimmer (p&lt;0.001), and NHR (p= 0.052) values were significantly increased in
the laser posterior cordotomy group as compared with the external arytenoid
lateralization group. No statistically significant difference was found between
the external arytenoid lateralization group and the laser posterior cordotomy
group in terms of the mean postoperative f(o) (p= 0.417), as well as for
decannulation time (p= 0.076) and duration of hospital stay (p= 2.30).Conclusions: External arytenoid
lateralization is a more preferable technique than laser posterior cordotomy because
it preserves mucosal integrity and cord mass, which results in better voice
quality.

Aim. To analyze the prevalence of different polymorphisms of AKT1 gene (rs2498796) and HEY2 gene (rs13328928) and to determine the association of revealed polymorphisms with the risk of endometrioid carcinoma in women living in the Republic of Tatarstan.
Methods. 161 female citizens of Tatarstan were enrolled. The study group included 60 patients with endometrial cancer (endometrioid carcinoma) and the control group enrolled 101 women without endometrial pathology. The age of the subjects ranged from 41 to 91 years. The single-nucleotide polymorphism of AKT1 gene (rs2498796) and HEY2 gene (rs13328928) was determined by real-time polymerase chain reaction. We ran a 2 test and evaluated the odds ratio.
Results. The risk of endometrial cancer was higher in carriers of homozygous T/T genotype of AKT1 gene (rs2498796) without statistical significance (OR=1.61, 95% CI=0.614.21, p=0.62). Homozygous C/C genotype of HEY2 gene (rs13328928) with the mutant allele C was observed in endometrial cancer group with a frequency of 0.383 and 0.287 in the control group (2=1.70, p=0.43). The risk of endometrial cancer was higher in the group of homozygous C/C genotype without statistical significance (OR=1.54, 95% CI=0.793.03, p=0.43).
Conclusion. Among 161 females citizens of the Republic of Tatarstan included into the study, the associations of the mutant alleles of AKT1 gene (rs2498796) and HEY2 gene (rs13328928) with the risk of endometrial cancer were not identified; the prevalence of alleles and genotypes was found to be comparable with the European one.
Change in muscle strength of the hand flexors, muscle-to-fat ratio and walking speed in ­middle-aged patients living in rural areas after myocardial infarction during cardiac rehabilitation

Published: October 2019

Aim. To estimate in dynamics the changes in muscle strength of hand flexors, muscle mass and gait rate in men with ischemic heart disease and myocardial infarction during cardiac rehabilitation at the outpatient polyclinic stage where daily dosed walking with individually selected frequency steps under self-control was used as a physical component.
Methods. The study included 66 men. Patients were divided into two groups comparable by age: 41 men with myocardial infarction (mean age 56.497.33 years) and 25 men with exertional angina without myocardial infarction (mean age 61.094.67 years). In all patients before and after 3 months of cardiac rehabilitation, where the physical component was represented by dosed walking, clinical and anamnestic characteristics were determined, muscle mass using bioimpedancemetry, muscle strength by wrist dynamometry, and walking speed using 6-minute walk test were measured. Statistical processing of the obtained materials was carried out by generally accepted methods.
Results. In patients with coronary heart disease and myocardial infarction, the muscle strength of the hand flexor on the right hand increased from 45.2611 daN to 46.37 daN (p=0.05) and on the left hand from 43.7811 to 43.7811 (p=0.05), absence of changes in muscle-to-fat tissue ratio 48.5 (47.7; 49.7) to 48.9 (48.5; 49.9) (p=0.08), increase in gait speed from 450 m (420; 500) to 480 m (440; 500) (p=0.05). In patients with coronary heart disease without myocardial infarction, muscle-to-fat tissue ratio decreased from 48.6 (47.7; 49.2) to 47.7 (46.5; 48.3) (p=0.04); gait speed decreased from 400 m (380; 431) to 390 m (350; 400) (p=0.05), the muscle strength of the hand flexors did not change (from 45.728.03 to 44.88 for the right hand (p=0.54) and from 42.1810 to 42.610 for the left hand (p=0.6).
Conclusion. After 3 months of cardiac rehabilitation at the outpatient polyclinic stage, patients with myocardial infarction had a positive effect reflected by muscle strength of flexors on both hands, insignificant increase of muscle mass relative to fat tissue and increase of gait speed as opposed to patients with coronary heart disease without myocardial infarction, who had a decrease in muscle strength of hand flexors, muscle-to-fat tissue ratio and gait speed during this period of time.

Published: October 2019

Transient leukemia of Down syndrome(TL-DS) or transient myeloproliferative disorder (TMD) or transient abnormal myelopoiesis (TAM) is a hematologic abnormality characterized by an uncontrolled proliferation of myeloblasts in peripheral blood and bone marrow which characteristically affects newborns and babies with Down syndrome. Children with Down syndrome (Trisomy 21) have a unique predisposition to develop myeloid leukemia of Down syndrome(ML-DS). In majority of cases of TL-DS, the GATA1 mutant clone goes into spontaneous remission without the need for chemotherapy. However, 10-20 % of neonates with TL-DS and silent TL-DS subsequently develop ML-DS in the first 5 years of life due to additional oncogenic mutations acquired by the persistent GATA1 mutant cells. We present here, one such case of Down syndrome with TL-DS in a neonate.

Impact of Hospital Readmissions Reduction Program Penalties on Hip and Knee Replacement Readmissions
Authors: Thirukumaran Caroline P. , McGarry Brian E. , Glance Laurent G. , Ying Meiling , Ricciardi Benjamin F. , Cai Xueya , Li Yue 
Published: October 2019

Background:
Little is known about the impact of the U.S. Centers for Medicare & Medicaid Services’ Hospital Readmissions Reduction Program (HRRP) expansion to include readmissions following elective primary total hip and knee replacements; the expansion was finalized in 2013 and was implemented in 2014. We examined whether hospitals at risk of relatively large penalties from this expansion experienced greater declines in joint replacement readmissions compared with hospitals at risk of smaller penalties.

Methods:
We used Medicare’s 2009 to 2016 Hospital Compare data sets to examine the impact of the HRRP’s expansion in the July 2013 to June 2016 period (post-expansion) compared with the July 2009 to June 2012 period (pre-expansion). The primary outcome was the hospital-level, 30-day, risk-standardized readmission rate (hereafter called the readmission rate) following joint replacement surgical procedures. We used the percentage of a hospital’s total inpatient revenue attributed to Medicare (categorized into quartiles) to represent the risk of penalties. We used hierarchical linear regression models to examine the adjusted impact of the HRRP’s expansion.

Results:
Our study cohort included 2,326 acute care hospitals. In the pre-HRRP expansion phase, the mean readmission rate was 5.36% among hospitals with the highest proportion of Medicare revenues (quartile 4) and 5.46% among hospitals with the lowest proportion of Medicare revenues (quartile 1). With the HRRP expansion, the readmission rate declined by 18.92% (1.01 percentage points) among quartile-4 hospitals and by 17.97% (0.98 percentage point) among quartile-1 hospitals (p = 0.45). This nonsignificant difference in readmission rate declines between quartiles persisted in multivariable analysis (a decline of 18.41% [0.98 percentage point] in quartile 4 and a decline of 17.35% [0.94 percentage point] in quartile 1; p = 0.35).

Conclusions:
The HRRP’s expansion to include joint replacements did not lead to greater reductions in postoperative readmissions among hospitals at risk of larger penalties in comparison with hospitals at risk of smaller penalties. Readmission rates were declining at similar rates among all hospitals, before and after the HRRP’s expansion.

Clinical Relevance:
Readmissions and complications following joint replacements are measures of the quality of surgical care. These events have important clinical and economic implications for patients and providers. This study is clinically relevant because it examines whether policy interventions, such as the HRRP, have the potential to reduce these unintended consequences of surgical care.
EARLIEST PETROXESTES BORINGS FROM SANDBIAN (EARLIEST LATE ORDOVICIAN) BRYOZOANS OF NORTHERN ESTONIA
Authors: VINN OLEV , WILSON MARK A. , TOOM URSULA 
Published: October 2019

ABSTRACT
The earliest Petroxestes borings were excavated in large trepostome bryozoans in the Sandbian (earliest Late Ordovician) of Estonia. The Estonian specimens are morphologically similar to the type material from the later Katian of North America. Petroxestes pera is rare in the Sandbian of Estonia and occurs only in biogenic hard substrates. Petroxestes borings occur in muddy environments that were preferred by macroborers in the Hirnantian and early Silurian of North America. It is possible that muddy environments supported higher bioerosion intensities and higher diversity of bioerosional traces in the shallow epicontinental seas of the Late Ordovician. The discovery of Petroxestes in the Sandbian of Estonia supports the idea that there was an earliest Late Ordovician peak in the diversification of borings in Baltica. It is possible that there was a migration of bioerosional trace makers from Baltica to Laurentia in the Late Ordovician.
