Authors: Amri Muhammad Miftahul , Sumiharto Raden
Published: February 2020

Nitrogen, Phosphorus and Potassium (NPK) are macro elements that important for the paddy development. NPK is a parameter that used for calculating fertilizer dosage. Current NPK measurement through laboratory requires a relatively long time, so we design a new system that can speed up the process and provide correct fertilizer dosage recommendations.This paper proposes an android based system using Local Binary Pattern (LBP) and Regression Analysis to measure soil nutrients and provide fertilizer dosage recommendations based on the LPT Bogor's formula. Samples of soil image taken from rice fields in Special Region of Yogyakarta. The measurement is processed by extracting LBP features from the soil image that has through the pre-processing stage. The extraction results were then analyzed using Multiple Linear Regression (MLR). The equation results from MLR is used to calculate NPK.The results show that the proposed system can detect NPK levels in paddy fields in Yogyakarta and provide fertilization dosage with an average detection accuracy of 70.65% (N 94.98%, P 50.84 %, and K 66.14%). The accuracy was obtained from the image taking at an optimal height of 70 cm and optimal angle of 0o to the ground surface. The average processing time is 0.61 seconds.

Authors: Perdana Guntur , Ashari Ahmad
Published: February 2020

Smart home system is a computer-aided system that will provide all comfort, safety, security and energy savings, which works automatically and programmed through a computer in a building or home. One of the method that can be used to design smart home is context aware method.  Context aware can work with the help of several other methods such as ontology method. Ontology has a variety of definition and always changes time by time. Ontology method is one of method that can process complex data. The ontology method allows complex reasoning and representation with better results. Constraints that are often encountered when designing a system that looks complex will face many problems such as many ambiguous domains. The existence of an ontology design before carrying out the prototype design of the smart home system will facilitate the smart home design process especially if the system will be made more complex so it would allows ambiguity from multiple domains. Testing with this ontology method is effective enough to minimize ambiguity from each domain, because each domain is designed with different characteristics. The results of the test concluded that the ontology design can be realized as a prototype of the smart home system.

Published: February 2020

The utilization of bare areas like narrow tract, building roof, or unused warehouse can be maximized as agricultural land using hydroponics system. Hydroponics is a cultivation technique by using nutrient solution. The plant nutrient is an alternative soil which relate with water acidity (pH), that has reaction with nutrient solubility to plant fertility. In fact, pH of the nutrients can change because of many factors like media of plant. The temperature of nutrient solution affect an ion nutrient absorption by plant root. The higher temperature reduces plant root ability to absorb water and ion nutrients. The more advanced technological developments, the agriculture can be controlled automatically and monitored remotely. The aim of this research is to make design control ph, volume and nutrients solution using fuzzy logic and zigbee pro communication for telematics control of plant hydroponics. The result of this experiment shown that fuzzy logic has effectiveness to control pH of hydroponics. It needs 429 seconds to setting point of range pH 5 ppm to 7 ppm and 459 seconds to setting point of range pH 9 ppm to 7 ppm.

Published: February 2020

Indonesia is a country that has unique weather that provides not only abundant natural resources but also can causes disasters at any time. To reduce the threat of losses, observing weather elements using a weather station is a solution that can be used. The development of systems related to environmental monitoring and weather stations is not new. However, most research focuses on various innovations in utilization, low cost and power savings. These studies have not touched on the aspect of ease of system development, especially in the concept of adding nodes. Indonesia, as a country with diverse regional topography, needs an integrated weather monitoring system with the concept of centralized data collection to get a complete picture.In this study, a portable mini weather station system was built named Amicagama. This system is built with the concept of high scalability which means the system is designed to be used publicly, with each user able to manage the nodes which are their respective weather stations. Management by each user here means that each user can manage weather data to be submitted, add nodes at a new location, and can delete nodes at a certain location if something unexpected happens.

There is a small but growing literature on large-scale statistical modeling of Chinese

language texts. Ouyang analyzed a corpus of over 40,000 ancient documents downloaded

from multiple sources. This was used to plot the temporal distributions of word frequencies

and geographic distributions of authors. Huang and Yu modeled the SongCi poetry corpus,

first converting it to tonally marked pinyin to conserve poetically important pronunciation

information. Nichols and colleagues reported initial modeling of the Chinese Text Project

corpus1 in a conference paper. (Further below, we describe differences between this corpus

and the Handian.) With additional collaborators, this group has now conducted two studies

that are currently unpublished but under review. In the first, they apply topic models to

address scholarly questions about the relationships among important texts of Ancient

Chinese philosophy. In the second, they use topic modeling to investigate the concepts of

mind and body in ancient Chinese philosophy. Although we share similar scholarly

objectives with these researchers, our approach in this paper is unique in that for the first

time anywhere we bring the benefits of computational modeling of ancient Chinese texts to a robust public platform that is mirrored on both sides of the Pacific. Besides being just a

useful portal to the texts, our approach foregrounds the interpretive issues surrounding topic models, and makes more sophisticated exploration and analysis of interpretive questions possible for experts and novices alike.
TROPHIC ECOLOGY OF GIRARDINICHTHYS MULTIRADIATUS (MEEK, 1904) (PISCES: GOODEIDAE) IN THE SALAZAR LAGOON, STATE OF MEXICO, MEXICO
Authors: Cruz-Gómez Adolfo , Franco-López Jonathan , Rodríguez-Varela Asela Del Carmen
Published: February 2020

Girardinichthys multiradiatus is a viviparous fish endemic to Mexico located in the Lerma, Balsas and Panuco Hydrological Basins. In the State of Mexico, it is distributed mainly in the Rio Lerma Basin, and despite the relevance of this species due to its endemism, studies on its food are scarce even though they are fundamental to the knowledge of its biology. The specimens were collected in the Salazar Lagoon, in total 204 stomachs of this species (82 females and 122 males) were examined during an annual cycle. Percentages in number, weight and frequency, Zander's food importance index and Levins trophic niche amplitude were obtained for the analysis of stomach content. G. multiradiatus consumed 14 type food items and according to Zander index bivalves and gastropods, were essential dietary food for both sexes during study period. According to Levins index, the niche amplitude was low, so it is considered a specialist. In Salazar, mollusks and crustaceans were the basis of G. multiradiatus' diet. This species is carnivorous and the results in Salazar show variations in their diet compared to other reservoirs studied, which makes it necessary to carry out more studies on their trophic ecology in the environments of the State of Mexico in order to propose alternatives of conservation.

Sanitasi dan Dampaknya bagi Kesehatan: Studi dari Pesantren
Authors: Fahham Achmad Muchaddam
Published: February 2020

According to the United Nations, sanitation is one of the basic human rights. Sanitation impacts the quality of human life, including in Islamic boarding schools - institutions that organized Islamic religious education. The Islamic boarding houses should meet the sanitation standard to create a conducive environment for the students. This study was conducted using a qualitative method to determine sanitation conditions of Islamic boarding school, the impact of sanitation on the school to students' health conditions, and government policies on sanitation problems faced by the boarding school. Data collection were conducted using in-depth interviews and literature studies, which then analyzed by reducing techniques and drawing conclusions. The study concluded that most Islamic boarding schools in various regions in Indonesia do not have sanitation that met health standards.  These conditions have an impact on the health of the students. Many of them have been exposed to scabies, diarrhea, and there were students who have been affected by ARI. There are two government policies implemented to help Islamic boarding schools dealing with sanitation problems: boarding schools health program of the ministry of health and eco-pesantren program of the ministry of environment. However, not all Islamic boarding school have access to any one of these programs.  Thus, the government needs to expand the coverage of the boarding school health program and eco-pesantren program. Menurut Perserikatan Bangsa-Bangsa sanitasi merupakan salah satu hak asasi manusia. Sanitasi memengaruhi kualitas hidup manusia, termasuk di pesantren yang merupakan institusi penyelenggaran pendidikan keagamaan Islam. Di pondok tempat tinggal santri seyogyanya memenuhi standar sanitasi agar santri dapat beraktivitas dengan nyaman sesuai dengan tuntunan Islam. Studi ini dilakukan dengan metode kualitatif untuk mengetahui kondisi sanitasi pesantren, dampak sanitasi pesantren terhadap kesehatan santri, dan kebijakan pemerintah terhadap masalah sanitasi yang dihadapi oleh pesantren. Pengumpulan data dilakukan dengan wawancara mendalam dan studi literatur, yang kemudian dianalisis dengan teknik reduksi dan penarikan kesimpulan. Studi ini menyimpulkan bahwa sebagian besar pesantren di berbagai wilayah di Indonesia belum memiliki sanitasi yang memenuhi syarat kesehatan. Kondisi sanitasi yang belum memenuhi syarat kesehatan tersebut memiliki dampak bagi kesehatan santri. Banyak santri yang pernah terkena skabies, diare, dan Infeksi Saluran Pernapasan Akut (ISPA). Ada dua kebijakan pemerintah yang dilaksanakan untuk membantu pesantren keluar dari masalah sanitasi yang dihadapinya, yakni Pos Kesehatan Pesantren dari Kementerian Kesehatan dan eco-pesantren Kementerian Lingkungan Hidup dan Kehutanan. Namun, belum semua pesantren dapat mengakses salah satu kebijakan tersebut. Untuk itu, Pemerintah perlu meningkatkan jangkauan program pos kesehatan pesantren dan eco-pesantren.

Data re-uploading for a universal quantum classifier
Authors: Pérez-Salinas Adrián , Cervera-Lierta Alba , Gil-Fuster Elies , Latorre José I.
Published: February 2020

A single qubit provides sufficient computational capabilities to construct a universal quantum classifier when assisted with a classical subroutine. This fact may be surprising since a single qubit only offers a simple superposition of two states and single-qubit gates only make a rotation in the Bloch sphere. The key ingredient to circumvent these limitations is to allow for multipledata re-uploading. A quantum circuit can then be organized as a series of data re-uploading and single-qubit processing units. Furthermore, both data re-uploading and measurements can accommodate multiple dimensions in the input and several categories in the output, to conform to a universal quantum classifier. The extension of this idea to several qubits enhances the efficiency of the strategy as entanglement expands the superpositions carried along with the classification. Extensive benchmarking on different examples of the single- and multi-qubit quantum classifier validates its ability to describe and classify complex data.
Completely positive master equation for arbitrary driving and small level spacing
Authors: Mozgunov Evgeny , Lidar Daniel
Published: February 2020

Markovian master equations are a ubiquitous tool in the study of open quantum systems, but deriving them from first principles involves a series of compromises. On the one hand, the Redfield equation is valid for fast environments (whose correlation function decays much faster than the system relaxation time) regardless of the relative strength of the coupling to the system Hamiltonian, but is notoriously non-completely-positive. On the other hand, the Davies equation preserves complete positivity but is valid only in the ultra-weak coupling limit and for systems with a finite level spacing, which makes it incompatible with arbitrarily fast time-dependent driving. Here we show that a recently derived Markovian coarse-grained master equation (CGME), already known to be completely positive, has a much expanded range of applicability compared to the Davies equation, and moreover, is locally generated and can be generalized to accommodate arbitrarily fast driving. This generalization, which we refer to as the time-dependent CGME, is thus suitable for the analysis of fast operations in gate-model quantum computing, such as quantum error correction and dynamical decoupling. Our derivation proceeds directly from the Redfield equation and allows us to place rigorous error bounds on all three equations: Redfield, Davies, and coarse-grained. Our main result is thus a completely positive Markovian master equation that is a controlled approximation to the true evolution for any time-dependence of the system Hamiltonian, and works for systems with arbitrarily small level spacing. We illustrate this with an analysis showing that dynamical decoupling can extend coherence times even in a strictly Markovian setting.

Editorial: A farmácia hospitalar brasileira e o Desafio Global para a Segurança do Paciente
Authors: Assunção Costa Lindemberg , Ribeiro Pinto Charleston
Published: February 2020

A Segurança do Paciente é um tema recente na área de Saúde. Foi a partir da publicação do relatório do Instituto de Medicina, nos Estados Unidos da América em 1999, intitulado “Errar é Humano”, que nasce esse novo campo do conhecimento aplicado à área de saúde que envolve várias disciplinas e conhecimentos sobre psicologia cognitiva, fatores humanos, trabalho de grupos e sociologia organizacional. O sistema de saúde brasileiro está bastante atrasado na aplicação desse novo saber quando comparado à ciência da segurança aplicada a outros setores como: na aviação, nas companhias geradoras de energia nuclear, na área espacial e em outras organizações que possuem alguns modelos de excelência. Dentro desse novo campo, encontra-se a segurança no uso dos medicamentos. Os medicamentos constituem um dos principais instrumentos terapêuticos e são, sem dúvida, os mais utilizados. O crescente interesse pelo estudo e a investigação de diversos aspectos relacionados com a farmacoterapia, desde a análise dos custos (Farmacoeconomia) até a avaliação da sua segurança (Farmacovigilância, segurança do paciente, erros de medicação), incluindo o impacto dos resíduos de medicamentos sobre o meio ambiente e o equilíbrio ecológico , são consequência deste amplo emprego.

The purpose of this study was to determine status, number and present level
of productivity of autochthonous goats raised in Central Serbia on
smallholder farms. Study included quality breeding animals of Balkan and
Serbian white goat breed registered in Central herd book. Productivity data
were collected from regular annual performance recordings at 11 smallholder
farms for 145 Balkan does (2-9 years of age) and 203 kids and 83 Serbian
white does (2-10 years of age) and 109 kids. Traits recorded were as
follows: body weight of does, body weight of kids at birth, at the age of 30
days and at weaning, prolificacy of does and milk production. The analysis
showed the average body weight of does to be 43.07 kg for Balkan does and
47.42 kg for Serbian white does. Average body weight of kids at birth, 30
days of age and weaning was 2.22 kg, 6.87 kg and 15.71 kg, respectively for
Balkan breed and 3.66 kg, 7.24 kg and 14.23 kg for Serbian white breed.
Prolificacy was 140% in Balkan and 131% in Serbian white does. Among dairy
production traits, following results were obtained for Balkan and Serbian
white goat respectively: lactation length 199 and 229 days, total milk yield
257.89 kg and 459.49 kg, milk fat content 4.03% and 3.79%, milk protein
content 3.06% and 3.35%. Number of quality breeding animals registered at
Central herd book in 2018, as presented in Institute for Animal Husbandry?s
annual report for goats for Central Serbia in 2018, was 159 for Balkan and
138 for Serbian white goat. As these breeds represent a valuable and
irreplaceable source of genetic variability, as well as very important
cultural and traditional heritage and further emphasis should be on
preserving and increasing their number.

The study included 201 offspring (108 castrated males and 93 females) of
Landrace (L), Large White (LW) and Pietrain (P) sires. The studied animals
were of following genotype: Landrace (L; n = 48); two breed crosses with
50:50 share of parental breeds (LWxL, n=32; and PxL, n=23), two breed
crosses with 75% of paternal breed [Lx(?LWxL), n=35] and [LWx(?LxWL) n=38]
and three breed crosses [Px(?LWxL) n=25]. Animals included in this study
were born during four seasons: winter (n=38), spring (n=65), summer (n=40)
and autumn (n=58). Studies have shown that, at an average weight of warm
carcass side of 81.20 kg, the highest average values for the weight of round
(RW; 10.204 kg), the weight of intermuscular fatty tissue (RINT; 0.478 kg),
bone tissue (RBT; 0.850 kg) and muscle tissue (RMT, 7.552 kg) in the round,
were established in three-breed crosses of Px (LWxL) genotype compared to
other genotypes. The least skin and subcutaneous fatty tissue (RST; 1.269
kg) was recorded in two breed crosses PxL. They had less skin and
subcutaneous fatty tissue by 454 g and 467 grams, respectively, compared to
two breed crosses (LWxL) and LWx (?LxLW). Research has shown that there is a
genotype on a farm that gives more muscle tissue in the round by 1.521 kg
[Px (?LWxL): LWx (?LWxL)] with the same weight of warm carcass side, which
is a very large difference. With the same average weight of warm carcass
side, female animals had higher average weight of the round and yield of
muscle tissue compared to male castrated animals. The effect of genotype
(P<0.001) on all investigated traits was recorded, also the effect of the
season of birth on the skin and subcutaneous fat tissue and on the weight of
intermuscular fat in the round was recorded. The effect of sex/gender was
significant (P<0.01) on the weight of skin and subcutaneous fat and on the
weight of the muscle tissues in the round but no significant effect on other
tested properties (P> 0.05) was observed.

Published: February 2020

Enriching table eggs with certain nutrients such as omega-3 fatty acids is an
ongoing topic. Therefore, the aforementioned research was carried out with
the aim of examining the possibility of feeding laying hens with ground flax
seed, flax cake and flaxseed oil and their influence on the ratio of omega-6
and omega-3 fatty acids of table eggs, as well as on certain production
parameters. The experiment was set up in a production facility with 192
consuming laying hens 27 weeks old. The laying hens were divided into 4
groups: control group; group fed with flax cake (10%) + flax oil (2%); a
group fed with 5% ground flax and a group fed with 10% ground flax. Each
group had 8 cages with 6 laying hens, a total of 48 laying hens per group.
The production parameters presented in this paper are as follows: number of
eggs per laying hen , egg weight and yolk weight. Egg quality indicators
were determined at the end of the 5th and 10th week from the start of the
experiment, namely: pH of egg white and yolk, polyunsaturated and saturated
fatty acids ratio, as well as omega-3 and omega-3 fatty acids ratio. The
results of the study showed that the inclusion of flax cake, flax oil and
ground flaxseed had no negative effects on the shown production parameters
and that there was a positive effect of these nutrients on the ratio of
omega-6 and omega-3 fatty acids in table eggs.

Published: February 2020

The aim of this work was a phenotypic description of the mare families of a
Lipizzan horse breed from stud Vucijak. A total of 31 mares were measured,
for every animal 28 measures were recorded. The mares are distributed by
mare families in the following: Sana (3), Lipa (3), Bregava (3), Cremica
(3), Ukrina (3), Visla (2), Neretva (3), Pliva (1), Drina (2), Sutjeska (2),
Sitnica (1), Janja (2) and Sava. Simple analysis of variance was done to
determine the difference in the morphological measures between mare
families. Also, correlation between 28 measures was done. This study
revealed phenotypic uniformity between mare families. Of the 28 measures
recorded, a statistically significant difference was identified only for the
length of cannon (front leg). The longest average length of the cannon
(front leg) had at Sana (24.67 cm), and the shortest at Bregava (19.00 cm).
The correlation ranged from slightly negative to highly positive with
correlation coefficients from -0.465 to 0.779. Significant and highly
significant correlation with height, length and depth was found in mare
measures. The body shape of the mare families has a rectangular, which is in
accordance with the Lipizzan horses from other stud in Europe. Also, the
study revealed that mares from Vucijak are smaller than mares from other
stud, which is in accordance with the breeding goals.
Biological features and productivity of Alpaca
Authors: Ponomareva Arina , Sycheva Irina
Published: February 2020

Alpaca domestication took place more than 6000 years ago. The Indians of Peru
discerned the potential in these animals, tamed them and began to breed. In
the past, alpacas were called the ?Inca gold?: they could provide people
with all the necessary resources for living. People dressed in skins, ate
meat, spun wool and made clothes, and used manure as fuel. An increase in
the number of livestock on the Russian Alpaca and Capri farms favorably
affects the further distribution of alpaca as a species in Russia. The
possibility of recognition of alpaca as an agricultural animal will be the
sale of wool, its processing, as well as the rejection of imported raw
materials.

The issue of Climate Change has raised so much attention for decades,
specifically in recent years. Modern trends in urban architecture which
tried to create living machines similar to each other in any context, have
now been proven to be insufficient and unless we decide to respect nature
and make our buildings cooperate with their contexts as soon as possible we
cannot address further threads regarding our future life. If we take a look
at traditional architecture existing in old towns and rural area, we can see
how people managed to bond a new construction with its surroundings. In this
article we study different architectural patterns which exists in old
architectures of towns and villages in Iran; the country which can be a good
case study due to its rich diversity of nature, climate zones and
architectural background. In Iran we have a range of climate of cities from
hot and dry to humid and very cold ones. So, depending on the city climate,
water supplies and energy sufficiency people tried to create best
residential buildings. Here we try to check out some examples.
Evaluation of the efficiency of university classrooms with the fuzzy logic
Authors: Diker Fadime
Published: February 2020

In this paper, a fuzzy logic algorithm was created in order to grade and
classify the design efficiencies of classrooms selected from S?leyman
Demirel University. The existing classrooms were examined on site and the
orientation of the classrooms, the number of people, the classroom area and
the window area of the classroom were calculated. As the input variables,
the orientation of the classrooms, the number of people, the area per-capita
and the ratio of window area to the classroom area were modelled. The design
efficiencies of the classrooms as the output variables were obtained by the
rules formed among the input variables. In the model, fuzzy model as the
Mamdani type and "weighted average" method as the clarification method were
used. For fuzzy logic model, 180 fuzzy rules have been formed in the type of
IF, which are associated with the facade of the classroom, the number of
people, the area per capita and the ratio of the window area of the
classrooms to the design efficiency of the classroom. Design efficiency of
the classrooms were created; the design efficiency classes and the average
design efficiencies of classrooms in faculties were compared and concluded
according to faculties. The efficiency of the classrooms, which is the main
place of the educational buildings, depends on the decisions taken during
the design phase. With the model created in this paper, more efficient
designs will be provided by having knowledge about the design efficiency
through making use of the decision-making process of the classrooms during
the design process.

Published: February 2020

Many structural designs are done without comprehensive consideration for
achieving optimum design. To achieve minimum mass optimization, a
mathematical model was developed in this study and subjected to British
Standard (BS 5950) code requirements for structural integrity as
constraints. Visual basic application (VBA) codes were written into a
spreadsheet environment to implement the model. The developed optimization
model was validated using different sample shed structures of same volume
(729m?) but of different height to span to length (H: b: L) ratios which
were obtained using the Ratio method and the Step size method. The best
parameter ratio of height to length to breadth obtained was 1:1:1 which is
similar to what was obtained by other authors. Parametric design case study
analysis was also performed for three different design situations with a
given span b, heights H and h and frame spacing S. The minimum masses of
steel for a fixed plan area of the buildings were obtained for each of the
three scenarios. It is recommended that design engineers should consider
varying major frame parameters such as frame spacing and heights at
pre-design stages in order to obtain optimal values of parameters which will
ensure economical structures.
Recommendations for urban revitalization of theater locations: A case study - Republic of Serbia
Authors: Vukajlov Ljiljana , Milinkovic Aleksandra , Brkljac Dijana
Published: February 2020

Theater location quality is researched according to a pre-formed model with
the aim to improve quality in the functioning of theaters in settlements of
the Republic of Serbia. An omnipresent process of globalization has led to
significant changes in the field of culture, and thus a reduction in
interest for classic theater performances has occurred. The poor condition
of theater buildings in architectural and structural terms as well as their
immediate environment, in urbanistic sense, is the result of neglecting the
field of culture on a national level for many years. By summing up the total
scores for specific urban aspects obtained on the basis of the conducted
research and previously collected data, it was found that the average score
of the location quality of theaters is 6 of maximum 10, based on the
established scoring and evaluation of the determined aspects within the
research. Since the active functioning of the theaters at the local level is
important for the development of the traditional culture of the population,
it is justified to propose specific measures transformation of the theater
immediate environment and to implement them as soon as possible for 30
existing theaters in the Republic of Serbia.

domain of interest in the field of industrial heritage. Due to the need to
expand existing housing capacities in urban areas, a large number of
industrial buildings are nowadays converted into multi-family and
single-family housing. The paper deals with the analysis of the functional
and aesthetic internal transformation of industrial into housing spaces. The
research goal is to determine the principles of conceptualization of housing
functional plan within the framework of the original physical structure of
the industrial building, at the architectonic composition level and housing
unit (dwelling) level. Besides, the paper aims to check the existence of
common patterns of the aesthetic transformation of converted spaces,
examined through three epochs of the development of industrial architecture:
the second half of the XIX century, the first half of the XX century and the
post-WWII period.
Slow and fast light propagation through ladder-type atomic media with degenerate energy levels
Authors: Filipovic Nikola , Pavlovic Vladan , Stevanovic Ljiljana
Published: February 2020

We investigate the weak probe pulse propagation through the atomic medium, in
the presence of the strong control laser field, under the regime of the
electromagnetically induced transparency (EIT). These fields couple to the
medium by forming the 3-level ladder configuration. We focus on two distinct
cases: closed system, which is a non-degenerate, and open system, where the
middle level is 3-fold degenerate, and the additional levels are coupled to
the other levels only via spontaneous emission. The spatio-temporal profile
of the probe pulse envelope is obtained by using the formalism of
Maxwell-Bloch equations with the help of the Fourier transform method. We
study the influence of the control field Rabi frequency, the spectral
half-width of the initial pulse and decay rates on the propagation of the
probe pulse. Several important pulse parameters are also calculated and
discussed. It is shown that the group velocity of light can be controlled in
such a manner that one can switch from slow to fast light and vice versa
when changing the control Rabi frequency and spectral pulse half-width.
Moreover, the possibility of replacing the open with an effective closed
system is also discussed.

Goal of this work is to establish technical feasibility and fundamentals of producing activated carbon from plane tree seeds biomass for porous materials derivation. Bio-chars produced via carbonization from plane tree seeds precursor were activated in CO2 at 750 and 850?C, during various residence times. Their surface area and porosity were characterized by N2 adsorption at 77 K. Surface areas of activated carbons can be correlated with kinetics mechanism and activation energy magnitudes of oxidation reaction by CO2, which are closely related to applied activation temperature. Result showed that high temperature activated carbon had higher gas adsorption as compared to activated carbon obtained from lower temperature during two-hour residence time. Breakthrough behavior was detected at 850?C where surface reactions dominate, and it is characterized by autocatalytic kinetic model under designed conditions. Both, temperature and CO2 concentration in vicinity of solid surface effect on breakthrough time of adsorbent. Derived bio-chars are converted into high quality activated carbons, with surface area of 776.55 m2/g, where micro-pores with pore diameters less than 2 nm prevail. Produced activated carbons have properties comparable with commercially available activated carbons, which can be successfully used for removal of harmful gaseous pollutants toward air purification.

The present study investigated the enhancement of energy conservation under the principles of pure substances that exercise phase change throughout charging and discharging processes. This work primarily focused on the thermal energy storage system, where the working medium charges the PCM namely (paraffin wax and stearic acid) that is normally encapsulated in spherical balls. The potentiality in charging of working medium was examined upon blending heat transfer fluid with four nanoparticles (Al2O3, CuO, TiO2, and MgO). Several volume concentration levels (0.2%, 0.5%, and 0.8%) were considered for afore mentioned nanoparticles under the influence of assumed flow rates (2, 4, and 6 L per minute). The experiments were carried out with various nanofluids used as heat transfer fluid for different flow rates and volume concentrations. The results showed that there is a considerable amount of reduction in charging time, in case of 6 L per minute, 0.8% volume concentration and PCM as paraffin wax, around 27.22% for TiO2 nanofluid, 36.66% for Al2O3 nanofluid, 40.90% for CuO nanofluid, and 63.63% for MgO nanofluid, and PCM used as stearic acid, around 26.31% for TiO2 nanofluid, 42.10% for Al2O3 nanofluid, 47.36% for CuO nanofluid, and 68.42% for MgO nanofluid, when compared with water as the conventional heat transfer fluid. From the results, it was observed that the effect of particle concentration played an important role in the heat transfer process. During the discharging process, 210 L of hot water withdrawn with paraffin wax used as PCM and 198 L of hot water withdrawn with stearic acid used as

Using numerical methods, the basic characteristics of heat and mass transfer processes in the furnace chamber of the BKZ-75 boiler of the Shakhtinskaya TPP (Kazakhstan) were studied during a forced partial stop of the supply of coal dust through the burners. Two modes of fuel supply were studied; a direct-flow method of supplying air mixtures, when two direct-flow burners are working and two are in emergency mode and vortex method of supplying air mixtures - two vortex burners with a swirl angle of the air mixture flow and their inclination the center of symmetry of the boiler by 30? and two are in emergency mode. The computational experiments allowed to obtain the distributions of the total velocity vector, temperature fields, concentration fields of CO, NO2 throughout the entire volume of the combustion chamber and conduct a comparative analysis for the two investigated emergency mode (direct-flow and vortex). Based on the results, it can be concluded that in the case of a forced partial stop of the supply of coal dust, the use of the vortex method of supplying air mixtures improves heat and mass transfer processes and allows minimizing emissions of harmful substances.

Buerger's disease is a rather rare pathology characterized by nonatherogenic vascular lesion associated with the inflammation in the intima of the vessel and the thrombus formation. Most often the pathological process affects small and medium caliber arteries. Vascular occlusion can lead to tissue ischemia and the trophic ulcers, and cause the extremity amputation. The disorder pathogenesis has not been fully explored. Literature data indicate that the disease development may be associated with autoimmune processes. The paper presents the results of immunohistochemical study of the material obtained after amputation of the lower extremity in a patient diagnosed with Buerger's disease. The patient had a 15-year tobacco smoking experience. In the inflammatory cell infiltrates around the affected vessels, lymphocytes with CD4, CD8 antigens and IgG immunoglobulin deposits were found, which could be considered as the evidence of the autoimmune mechanisms’ involvment. Immunohistochemical reactions with markers of NK cells CD56 and the central component of the C3d complement system were negative. The results of the study suggest that the key role is played by helper and suppressor T lymphocytes, as well as by humoral antibodies of the IgG class.
Prognosis criteria of the severe postembolization syndrome in patients with uterine myoma

Recently specialists take an interest in organ-preserving methods of uterine fibroids treatment, one of which is uterine artery embolization (UAE). One of the method’s negative aspects is the severe postembolization syndrome (PES) development, requiring timely initiation of adequate treatment in order to avoid severe complications that could lead to the organ removal. The study was aimed to search for the prognostic criteria of the severe PES development during the preoperative period. The study included 81 UAE-treated women aged 19–50 with 7–17 week uterine myoma. The patients’ anthropometric measurements were used, as well as the skin microcirculation data obtained by laser Doppler flowmetry together with the occlusion test. Based on prognostic criteria, models with AUC (area under ROC curve) > 0.8 were presented. According to the models, the anthropometric predictors of the severe PES were the following: age under 38.5 (p < 0.05); BMI lower than 25 kg/m2 (р < 0.05), and microcirculation value (M) prior to UAE below 9.55 PU (р = 0.001). Microvascular blood flow during the occlusion test indicate that the higher the oxygen consumption index (I), intravascular resistance (Rc), capillary blood flow reserve capacity in the models, the higher the risk of the severe PES development (p < 0.05). Low alpha angle value obtained by the occlusion test (p = 0.003) as well as the UVLF value (p = 0.004) in the models also indicate the increased risk of severe PES. Multidimensional prognostic modelling admits to expect the severe PES development prior to UAE, which allows the doctor to prepare the woman for specific management and treatment.
