Must the Show Go On? The (In)Ability of Counterevidence to Change Attitudes Toward Crime Control Theater Policies
Authors: Campbell Dylan , Newheiser Anna
Published: June 2019

Objectives: Crime control theater refers to intuitively appealing laws that appear to address crime while lacking any evidence that they actually do so (e.g., sex offender registration and residence restriction laws, which do not reduce recidivism). Despite their ineffectiveness, public support for such laws is high. Hypotheses: We predicted that making people aware of these laws’ failure to reduce crime would lower support for them.Method: Participants (recruited from Mechanical Turk; Study 1: N=298, mean age=35.60, 47.7% self-identified as women and 75.8% as White; Study 2: N=147, mean age=35.03, 40.1% self-identified as women and 85.0% as White; Study 3: N=552, mean age=35.86, 42.9% self-identified as women and 76.4% as White) read about sex offender registration and residence restriction policies and rated their support for these laws, confidence in their opinions about them, and perceptions of their efficacy before and after reading counterevidence highlighting these laws’ failure to reduce sex crimes. Results: Although exposure to counterevidence somewhat lowered support (average within-subjects d=-0.69), general attitudes remained positive even at the post-counterevidence phase (average d=0.46 against the scale midpoint). This pattern held when manipulating the criminal population being targeted (sex offenders vs. white-collar offenders; Study 1), when tailoring counterevidence to people’s self-stated justifications for supporting these laws (Studies 2-3), and despite favorable ratings of the counterevidence’s strength and credibility. Conclusion: Support for crime control theater policies persists despite explicit knowledge that they do not reduce crime, highlighting the need for alternative methods of dissuading people from their support for these ineffective laws.
A Hidden Markov Model for Analyzing Eye-Tracking of Moving Objects
Authors: Kim Jaeah , Singh Shashank , Thiessen Erik , Fisher Anna
Published: June 2019

Eye-tracking provides an opportunity to generate and analyze high-density data relevant to understanding cognition. However, while events in the real world are often dynamic, eye-tracking paradigms are typically limited to assessing gaze toward static objects. In this study, we propose a generative framework, based on a hidden Markov model (HMM), for using eye-tracking data to analyze behavior in the context of multiple moving objects of interest. We apply this framework to analyze data from a recent visual object tracking task paradigm, TrackIt, for studying selective sustained attention in children. Within this paradigm, we present two validation experiments to show that the HMM provides a viable approach to studying eye-tracking data with moving stimuli, and to illustrate the benefits of the HMM approach over some more naive possible approaches. The first experiment utilizes a novel `supervised' variant of TrackIt, while the second compares directly with judgments made by human coders using data from the original TrackIt task. Our results suggest that the HMM-based method provides a robust analysis of eye-tracking data with moving stimuli, both for adults and for children as young as 3.5-6 years old.
Activity in the right frontal cortex is dependent on inhibitory-demand: a functional near infrared spectroscopy study
Authors: He Jason , Steiner Genevieve , Fogarty Jack , Nuzum Nathan , Finch Miki , Kruitwagen Saskia , Sage Nathan , Teo Wei-Peng
Published: June 2019

The ability to supress inappropriate or unwanted behaviour, known as inhibition, can be indexed using a variety of task paradigms, one of the more common being the Go/No-go task. Studies in which popular neuroimaging methods such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) were used to measure neural activity during participant performance of the Go/No-go task have often identified ‘inhibitory-related’ activity in the right prefrontal cortex (PFC). While studies using functional near-infrared spectroscopy (fNIRS) have also identified changes in activity in the right PFC, the variants of the Go/No-go tasks previously employed in those studies have made it difficult to be confident that those changes measured using fNIRS were specifically related to inhibition. To determine whether the change in activity identified in the right PFC with fNIRS by previous studies using the Go/No-go task were indeed related to inhibition, we had participants complete three conditions of the Go/No-go task, each with varying levels of inhibitory demand (manipulated by the relative frequency of Go to No-go trials). We found that as Go-trial frequency increased, participants performed faster on Go-trials and less accurately on No-go trials. More importantly, as inhibitory-demand increased, activity in the right but not left PFC increased. When taken together, these findings are in support of the idea that the changes measured in the right PFC in earlier studies using fNIRS during the Go/No-go task were indeed related to inhibition.

Authors: Sharma Aakriti , Sapkota Ranjan , Thapa Bibhusal , Sayami Prakash
Published: June 2019

Introduction: Empyema thoracis is an uncommon complication of childhood pneumonias but a common problem faced by a thoracic surgeon. Its management is still controversial, with a range of treatment options available and evolving gradually towards adoption of video-assisted thoracoscopic surgery (VATS) as the most commonly practiced one.

Aim: The aim of this study was to review our experience in pediatric empyema thoracis.

Methods: It was a retrospective review of the prospectively recorded data, spanning a period of 18 months in the Department of Cardio-Thoracic and Vascular Surgery in Manmohan Cardio-Thoracic Vascular and Transplant Center.

Results: A total of 40 consecutive patients, 29 males and 11 females, aged 15 years or less were operated upon for a diagnosis of empyema thoracis made based on clinical, radiological and laboratory evidence. All of them were referred patients, mostly from pediatricians. VATS was undertaken in 36 of them, the remaining four treated by open approach. Deloculation sufficed in majority (26/40; 65%) of the patients which mostly (23/26; 90%) had either acute or subacute presentation. Decortication was required in 35% (14/40) of the patients. However, all of the patients but one had a successful outcome in terms of lung expansion, sterilization of the pleural cavity and absence of recurrence. There was no operative mortality.

Conclusion: Surgical management of pediatric thoracic empyema is feasible and safe with favorable outcome. VATS is gradually becoming the more favored modality of operative management.

Published: June 2019

Introduction: Computed tomography (CT) is the ‘gold standard’ for detecting subarachnoid hemorrhage (SAH) and digital subtraction angiography (DSA) for visualizing the vascular pathology. There is some correlation between the pattern (based on Fisher grading) and location of bleed on CT scan and eventual location of cerebral aneurysm(s). Our aim was to assess the correlation between distribution of hemorrhage on the initial CT scan and eventual site of the ruptured aneurysm at our institution.

Methods: This retrospective review of prospectively collected data consisted of 50 patients with SAH over 8 months period. CT scan of patients performed within 72 hours after the ictus with suspected SAH were included in the study. Four neurosurgeons, who had at least three years of experience after being qualified, who were blind to the imaging studies, analyzed and scored independently the quantity and distribution of the hemorrhage on CT. Their prediction of the site of the ruptured aneurysm was recorded and this was correlated with the CT angiography (CTA) and/ or DSA findings.

Results: Overall accuracy of prediction was 71.6 % (68.2-75%). Parenchymal cerebral hematoma was an excellent predictor for the site of a ruptured aneurysm but was present in only a few cases (16%). The next valid predictor was blood distribution on CT for ruptured anterior communicating artery (ACom) and middle cerebral artery (MCA) aneurysms (89.4% and 85% respectively). Pattern of blood on CT together with CTA/DSA findings was found to be reliable for identifying the ruptured aneurysm in patients with multiple aneurysms in all cases.

Conclusion: The quantity and pattern of the blood on CT is a fairly reliable and quick tool for locating a ruptured MCA or ACom aneurysms. It is not, however, reliable for locating other ruptured aneurysms.
Segment III bypass: An Option to Palliate Proximal Biliary Obstruction
Authors: Bhandari Ramesh Singh
Published: June 2019

Introduction: In the era of minimally invasive therapy, endoscopic or interventional radiological techniques have become preferred technique for palliating advanced malignant hilar obstruction due to carcinoma gallbladder or cholangiocarcionmas. However, in selected group of these locally advanced unresectable disease and fit patients, surgical segment III bypass could still be a viable option for palliation.

Methods: I retrospectively reviewed the medical records of all the patients of segment III bypass performed over last six years (Oct 2012- May 2018) and analyzed the indication, perioperative morbidity, symptom relief and survival.

Results: Total 17 patients underwent palliative biliary bypass over the specified period. Among them 8 patients underwent segment three III biliary bypass for proximal biliary obstruction. Except 1 patient, all segment three bypass were offered to malignant proximal biliary obstruction. One patient developed postoperative sepsis and had mortality on day 7. Symptom relief in the form of relief of pruritus, improved sleep pattern and improved appetite was seen in 5 patients. In remaining 2 patients, the bilirubin didn’t drop to normal level and the symptom reliefs were partial. However, the patient had good satisfaction over not having an external tube attached to their body. Despite the patent anastomosis, failure in dropping bilirubin level significantly was considered due to segmental obstructions. One patient survived for 18months, 1 had follow up to 13 months. Three patients were lost to follow up after 3 months. Two patients had six weeks follow up and were symptomatically doing better.

Conclusion: Surgical segment III bypass is still a good option for palliating malignant hilar obstruction in selected group of patients.

Authors: Paudyal Pooja , Baral Josie , Gurung Geeta , Rana Ashma , Rawal Suniti , Singh Meeta
Published: June 2019

Introduction: Pyometra is the accumulation of purulent fluid in the uterine cavity caused by impaired drainage of pus due to benign or malignant conditions; rarely with resultant spontaneous uterine perforation brought about by uterine distension.

Cases: We report three consecutive cases of spontaneous perforated pyometra in postmenopausal elderly women aged 60 to 70 years who presented with acute abdomen, initially diagnosed as hollow viscus perforation, demonstrated of having significant uterine perforation at laparotomy for which hysterectomy with bilateral salpingo-oophorectomy were done. Histopathological examination revealed features of necrosis of stroma with chronic endometritis without any evidence of malignancy in all the three cases.

Conclusion: Spontaneous perforated pyometra, a grave complication necessitating prompt intervention, should always be kept as a possibility in all cases of suspected pyoperitoneum and acute abdomen in elderly postmenopausal women.

Published: June 2019

The desire to increase the thermodynamic efficiency of power machines and units now leads to use of gas turbine units with heat recovery in the cycle. Such devices are used as power and transport GTUs, as well as energy conversion units for prospective fourth generation nuclear power plants. Thermodynamic efficiency of the ideal Brighton cycle with heat regeneration with constant thermophysical properties of the working fluid, as well as the Brighton cycle with heat recovery and the wetting of the working fluid at the inlet to the turbine (with variable thermophysical properties of the working fluid) is considered in this paper. The inapplicability of comparison of the thermal efficiency of the Brighton cycle with heat recovery and the wetting of the working fluid at the inlet to the turbine with the thermal efficiency of the equivalent ideal Carnot cycle is shown.

Authors: Geletukha G.G. , Zheliezna T.A. , Bashtovyi A.I.
Published: June 2019

The purpose of the work is to develop recommendations for the implementation of long-term planning in Ukraine’s heat supply sector. The tasks of the work consist in a review of European experience in this field, analysis of the relevant Ukrainian legislation, and determining directions for its improvement. The methods of research include the study of literary, statistical and other data, analysis of regulatory acts. It is shown that lately there have been stable negative trends in the district heating (DH) sector of Ukraine, while the state policy in this area is now uncertain. At present, in the country there are virtually no national and regional strategic documents that contribute to the long-term planning of district heating. The working Concept of implementation of the state policy in the field of heat supply has a number of shortcomings and cannot be a sufficient basis for the implementation of planning at the national level. City heat supply schemes, which are the only regional-level document in the field of heat supply, are not binding for realization and do not take into account the targets of relevant national-level documents. Normative legal acts of Ukraine that regulate relations in the field of heat supply, require considerable revision and introduction of the norms that establish the procedure for the implementation of long-term planning in the DH sector. It is advisable to keep district heating in Ukraine and develop efficient DH systems with the aim to provide the population of the country with reliable and high-quality heat supply. The first steps in this direction should include the development of the Heat Supply Strategy by 2035, implementation of the zoning principle while developing heat supply schemes and making the schemes mandatory for implementation. In addition, it is necessary to ensure the consistency of the target indicators included in the regional (city) heat supply schemes with the corresponding national targets.

Published: June 2019

The results of experimental studies of the specific heat of crystallization of polymer composites based on polyethylene filled with copper microparticles are presented. Data concerning the effects on the crystallization heat of the studied composites on such factors as the mass fraction of the filler and the cooling rate of the composites from the melt are presented. The corresponding studies were performed with a change in the mass fraction of the filler from 0.3% to 4.0% and the cooling velocity of the microcomposite from the melt from 1 K/min to 20 K/min. It is shown that the specific heat of crystallization decreases significantly with increasing speed VT and the mass fraction of the filler ω. The results of the comparison of the values of the specific heat of crystallization of polymer microcomposite, obtained by a method based on the mixing of components in a dry form and in a polymer melt, are presented. It was established that the first of the indicated methods correspond to large values of the heat of crystallization.
EFFECT OF WATER TEMPERATURE AT INLET TO THE STEAM GENERATING CHANNEL ON STABILITY OF THE TWO-PHASE FLOW
Authors: Kovetskaya M.M.
Published: June 2019

The paper considers the influence of the coolant temperature on stability of the flow in the closed loop of thermal-hydraulic test bench in the natural circulation mode. The loop includes a lifting section with a heated and unheated zone, condenser and lowering section where the single-phase coolant flows. The regime is considered, when the heat flow on the wall of the heated channel remains constant and the temperature of the coolant inlet increases.

The effect of underheating at entrance to heated channel on the stability of the natural circulation of the coolant is considered. A one dimensional unsteady mathematical model of a two-phase coolant flow is presented. Boundaries of natural circulation instability region are determined depending on the coolant underheating at the entrance to the heated channel. Fluctuations in coolant flow rate are characterized by regular shape and an antiphase change in the flow rate at the outlet.

The ambiguous effect of underheating of the coolant at the entrance to the steam generating channel on the boundary of the stability of a two-phase flow is shown: at low values of underheating, its increasing destabilizes flow; at large underheating its increasing stabilizes the flow.

Authors: Simeiko K.V.
Published: June 2019

Supply of heat through combustion of organic fuel is impossible or economically unviable for the raw of high temperature processes due to it’s technological peculiarities. Some of these processes can be carried out in electrothermal fluidized bed reactors. Development of appropriate mathematical model for heat balance will allow prognostication of capacity needed to carry out specific process and improvement of electrothermal fluidized bed reactor.

During the development of mathematical model methods of heat-mass exchange theory were applied.  Verification of appropriateness for mathematical model was carried out through comparison of experimental results and calculated values of the amount of heat needed to perform the process of methane pyrolysis in electrothermal fluidized bed and coefficient of thermal efficiency of electrothermal fluidized bed reactor.

Comparison with real thermochemical process in electrothermal fluidized bed reactor confirms the appropriateness of mathematical model. Average deviation of mathematical model of heat balance and coefficient of thermal efficiency from obtained experimental values is 5…7 % and 6…9 % respectively. Proposed mathematical model can be applied in design of electrothermal fluidized bed reactors.

Published: June 2019

The review presents approaches with respect to the properties of the Earth’s climate system, which do not coincide with generally accepted ones. The results of recent studies show a more complex (stepwise) temporal dynamics of global temperature, which suggests the presence of a thermoregulatory mechanism in the climate system, which, if identified, will be able to estimate the likelihood of a transition to an increase or decrease in global temperature. The results of studies of the mechanism of solar-magnetic activity as the main cause of global warming are also given.
REDUCTION OF NATURAL GAS CONSUMPTION AND REDUCTION OF EMISSIONS WITH COMBUSTION PRODUCTS IN MUNICIPAL HEAT SUPPLY
Authors: Sigal O. , Pavlyuk N. , Pashyhin S.
Published: June 2019

The technical solutions are proposed to reduce the consumption of natural gas, as well as to reduce emissions with combustion products in the municipal heat supply systems:

- New constructions of water-tube and water-fire-tube boilers with improved technical, economic and environmental characteristics have been developed. Replacing of old boilers with these boilers within Ukraine will provide an economic effect of about 100 thousand tons of fuel equivalent per year. NOx reduction will be up to 35%;

- The new temperature mode for heating networks 115/70 oС has been developed, which provides the amount of heat that is adequate to the needs of consumers, and is appropriate for use in cities of the country from an economic point of view. However, the implementation of such reduced temperature mode requires a corresponding change in the general requirements when issuing "Technical Specifications" for connection to district heating systems, necessitates changes in the temperature mode values in other documents, for example the general plan of the city, as well as the possible need to change the calculated heat loads in concluded contracts for heat supply to consumers.  Nevertheless, the correction of temperature modes of cities should be considered as one of the possible measures to improve the energy efficiency of heat supply systems;

- The expediency of partial replacement of natural gas in the municipal heat supply systems of large cities of Ukraine with municipal solid waste (MSW) has been proved. The ways of improving the efficiency of mixed MSW combustion in conditions of country, including the extraction of "wet" biowaste from the total mass of mixed MSW with using a separate collection. are determined;

- To achieve compliance with the new more stringent European environmental standards, the highly efficient devices for cleaning combustion products from particulate matter and sulfur oxides have been developed. The efficiency of dust removal in centrifugal filters is 90...98%, in cyclone dust collectors - 90...93%. Desulfurization efficiency is up to 50%.

Published: June 2019

Improving the quality of hydrometeorological products and services for different categories of end users today is the most important task of the Hydrometeorological Service of Ukraine. Implementation of these measures involves a widespread use of modern technologies of hydrometeorological measurements as well as information and computing technologies such as Internet of Things, Big Data, Cloud Computing. The paper studies the current state and prospects of Internet of Things (IoT) application in hydrometeorological activities, particularly, in the work of hydrometeorological organizations of the State Emergency Service of Ukraine, in order to improve the quality of hydrometeorological products and services. Emergence of IoT became a new step in Internet and Web technologies use and ensured transition from static network to dynamic array of devices of all types and sizes employing electronics, software, sensors and network connectivity. It offers recommendations for intensifying the efforts aimed at implementation of this promising information technology into routine instrumental measurements, data collection and processing, as well as delivery of services to users. The recommendations present solutions to a number of technological, organizational and legal problems. Transition to a new technology should be carried out in stages and in the course of sensors and devices improvement, increase of speed and a reliability of communication channels. The most optimum solution may include a program-target approach based on a comprehensive program of development of the Hydrometeorological Service for the period of up to 5 years. This approach will make it possible to consider development of information technologies in a close relation with development of other activities of the Hydrometeorological Service: technical re-equipment of observation networks, improvement of the Hydrometeorological Service management as a whole and with regard to its separate units; strengthening its material and technical base, personnel potential etc.
Zones of intensive interactions over the North Atlantic, 700 hPa level, November
Authors: Serga E. N. , Serga I. N.
Published: June 2019

The methods of cluster and component analysis were applied to the existing factors that are associated with the characteristics of heat and moisture exchange at 700 hPa level before their inclusion in the model of regional climates imitation, in order to detect zones of active interaction in the atmosphere over the North Atlantic and determine the regions hosting the processes that cause a significant impact on formation of features of climatic responsive regimes in the Eastern Europe. Each node of a 2,5º2,5º grid covering the North Atlantic has the first three main components identified and they describe more than 80 % of the total dispersion of the interaction processes at 700 hPa level. Using the Universal Iterative Method of data clustering the study defines the homogeneous regions in the fields of main components of vectors of state of meteorological characteristics at 700 hPa level over the North Atlantic. It also specifies a physical and statistical analysis of the obtained clustering schemes which has a good scientific substantiation and shows that the clusters of the first main component are of a large-scale type, and the second and third components have a focal character. At 700 hPa level clusters differ in the intensity of interaction processes. The intensity of processes is characterized by distribution and magnitude of weight loads, average values of representative vectors and intra-cluster dispersion. We determined that the first main component makes the basic contribution to the formation of the majority of initial meteorological values, and the third main component reflects the influence of local features on interaction processes. These facts are confirmed by the manner in which loads over the studied region are distributed on the initial characteristics of atmospheric processes. Intra-cluster dispersion reflects the degree of diversity of these processes by region. The study identifies correspondence of the high-altitude homogeneous zones of the main components to the near-surface cyclic energy-active ocean zones.

Published: June 2019

Whole yogurt is a very consumed food in Brazil, but like any dairy derivative, susceptible to contamination. The objetive of the work was to detect the presence of psychrotrophic and proteolytic psychrotrophic bacterium in whole yoghurt, since these are bacterium indicative of their microbiological quality. The results found were not satisfactory for the psychrotrophic count, because although Brazilian legislation does not stipulate maximum limits for these microorganisms, their presence is undesirable because they cause economic losses, among other problems. Four analyzes were carried out during the period of validity of the yogurt, where the first sample (day 0) had a count of 8.0x102, the second one (day 7) had a reduction of 50%, (4.0x102) The third sample (day 21), 0.5x102 and the last analysis was negative. In order to count proteolytic psychrotrophics, there was no detection of viable microorganisms, but despite this, their enzymes can act on the yogurt components causing changes, which was not evaluated in the present research. It is concluded that despite efforts to maintain quality, there are still shortcomings in the manufacturing process, stressing the need to control the production stages of yogurt and obtaining a milk with good quality, since this is the main raw material in the production of yogurt.

The Relocation of Transcendence
Authors: Thurfjell David , Rubow Cecilie , Remmel Atko , Ohlsson Henrik
Published: June 2019

Denmark, Estonia, and Sweden are, if measured by certain sociological criteria, considered to be three of the world’s most secular countries. Nature—forests, pristine beaches, and the countryside—plays a specific role in the allegedly secular discourse of the mainstream populations of these nations. Not only is it almost without exception deemed as a positive asset worthy of protection, it is also thought of as holding certain existential qualities. Based on ethnographic fieldwork and interviews, this article suggests that Alfred Schutz’s conceptualization of transcendence—further developed by Thomas Luckmann—can be used to describe the existential experiences in nature of contemporary secular people. The article results in a suggestion for an operational definition of transcendence.
Effect of 2,4-D and BA on the establishment of cell suspension from nodes and internodes of Capsicum annuum cv. Etna
Authors: ALVES DOS SANTOS MAURICIO REGINALDO , SOUZA CAROLINA
Published: June 2019

In vitro cell suspension cultivation systems have been largely reported as safe and standardized methods for production of secondary metabolites with medicinal and agricultural interest. Capsicum annuum is one of the most widely grown vegetable in the world and its biological activities have been demonstrated against insects, fungi, bacteria and other groups of organisms. The determination of procedures for the dedifferentiation of cells into callus cells and the subsequent study of the callus growth pattern are necessary for the establishment of cell suspensions and also to subsidize studies regarding the bioactivity of its secondary metabolites. The objective of this study was to establish a protocol for dedifferentiation of leaf cells of the cultivar C. annuum cv. Etna and to determine the growth pattern of the calluses with a focus on the deceleration phase, when the callus cells must be subcultured into a liquid medium in order to establish cell suspension cultivations aiming at the production of secondary metabolites. treatment that resulted in the highest %CI, ACCC and callus weight was the combination of 4.52 µM 2,4-D + 0.44 µM BA. The calluses produced were friable and whitish and their growth pattern followed a sigmoid shape. The deceleration phase started on the 23rd day of cultivation. Callus induction in leaf explants of C. annuum cv. Etna can be achieved in MS medium supplemented with 4.52 µM 2,4-D + 0.44 µM BA, which results in high cellular proliferation; in order to start a cell suspension culture, callus cells on the 23rd day of culture should be used.

Odabir adekvatnog orošivača za zaštitu višegodišnjih nasada ovisi o puno čimbenika. Najvažnija je kakvoća depozicije škropiva. Kupcu orošivača kod odluke za kupnju od pomoći su i neovisni popisi mlaznica i strojeva, koji omogućavaju određeni stupanj redukcije zanošenja škropiva. Slovenski proizvođači Agromehanika i Zupan imaju određene serije orošivača i na pozitivnoj su listi Kooperation der Regionen, što znači da omogućavaju orošavanja s manjim gubicima škropiva. Za smanjenje zanošenja, vinogradar može odabrati i reciklažne tunelske orošivače. Povećanje površinskog učinka orošavanja moguće je upotrebom višerednih orošivača, koji mogu biti reciklažne konstrukcije ili s adekvatnim usmjerivačima zraka.

Cilj istraživanja bio je utvrđivanje protokola za mikropropagaciju kupine sorte ‘Reuben’. Vegetacijski vršci izolirani su aseptično pod stereomikroskopom iz aksilarnih pupova i postavljeni na medij za uspostavljanje kulture (EM). Na mediju za proliferaciju (PM) ispitivan je utjecaj šećera u dvije varijante: s dodanih 30 g L-1 saharoze ili 20 g L-1 glukoze + 10 g L-1 saharoze. Da bi se utvrdila optimalna vrsta i koncentracija citokinina za mikropropagaciju, u drugom pokusu ispitano je 5 tretmana: 6-benzilaminopurin (BAP) u koncentracijama 1 mg L-1 i 0,3 mg L-1, meta-topolin (mT) u jednakim koncentracijama te kao kontrola, medij bez hormona. Zakorjenjivanje in vitro provedeno je u dvije varijante, na mediju s dodanom indolil-3-octenom kiselinom (IAA) u koncentraciji 1 mg L-1 i na mediju bez hormona. Najveći broj izdanaka po eksplantatu (2,6) dobiven je na mediju s 1 mg L-1 BAP-a, ali su oni ujedno bili najkraći. Najdulji izdanci dobiveni su na mediju s 0,3 mg L-1 BAP-a ili mT kao i na mediju bez hormona. Postotak zakorjenjivanja bio je viši (61%) na mediju za zakorjenjivanje bez hormona. Aklimatizacija je bila uspješna i iznosila 92%-95%, ovisno o mediju za zakorjenjivanje.

Las enfermedades crónicas infantiles influyen negativamente en el desarrollo psicológico. Los niños y adolescentes con enfermedades crónicas digestivas presentan de forma predominante síntomas ansiosos y depresivos. Factores ambientales como el manejo de la sintomatología, la influencia de la respuesta de los pares o de la propia familia pueden determinar el manejo que de la enfermedad tenga el paciente. Estos aspectos son muy relevantes en enfermedades como la Enfermedad de Crohn, la Colitis Ulcerosa, el Dolor Abdominal Recurrente y los Vómitos Psicógenos. Los factores psicológicos que afectan a enfermedades médicas y/o la presencia comórbida de patología mental disminuyen la calidad de vida de estos pacientes afectando también al sistema familiar. La medicina psicosomática aborda estos aspectos de dichas patologías ayudando al paciente y a sus familias. Un abordaje integral por parte digestivo y de salud mental incrementa la salud percibida de los niños y adolescentes con patología digestiva crónica.

Las enfermedades crónicas infantiles tienen una gran influencia no sólo en lo físico, sino también en el desarrollo psicológico de los niños y adolescentes. Las enfermedades renales son frecuentes en este grupo de edad, presentan fundamentalmente síntomas ansiosos y depresivos, baja autoestima, además de los efectos secundarios de la inmunosupresión. Debido a que son patologías de características crónicas, con gran impacto de los procedimientos diagnósticos y terapéuticos y el alto riesgo de hospitalizaciones para recibir el tratamiento idóneo, conllevan una alteración del funcionamiento (social, familiar, escolar) habitual de los niños y adolescentes. Por lo que es importante, un abordaje multidisciplinar en estos casos, debido a la influencia de los factores psicológicos para minimizar el impacto de la patología, mejorar el curso y la adherencia terapéutica en este tipo de enfermedades de características crónicas.

A study was conducted to estimate the optimal levels of energy, protein, and fiber in the diets of New Zealand White (NZW) growing rabbits fed on fresh green forage available in North Vietnam. Mathematical modelling of nutrient-response curves was applied for the study. A total of 125 male growing rabbits at 6 weeks of age were randomly divided into 25 groups of 5 each to be fed on diets with an array of different levels of metabolizable energy (ME), crude protein (CP), and acid detergent fiber (ADF) by means of varying the ratio between fiber rich grasses, viz. elephant grass (Pennisetum purpureum), Setaria grass (Setaria sphacelata), or Para grass (Brachiaria mutica), and protein rich forages, viz. water spinach (Ipomoea aquatica) vines, sweet potato (Ipomoea batatas) vines, or Trichantera leaves (Trichanthera gigantea), in the basal diets. The average daily gain (ADG) and feed conversion ratio (FCR) were used as key responses of the rabbits to varied levels of ME, CP, and ADF in the diets. The results showed that the levels of ME, CP, and ADF in the diets strongly affected the ADG and FCR of the rabbits following curvilinear patterns with the highest ADG and lowest FCR when the diet contained 2106-2162 Kcal ME kg-1 DM with 16.5-16.8% CP and 21.9-22.4% ADF. Therefore, these levels of nutrients were considered to be optimal in the diets of NZW growing rabbits fed on local forages.

The association of the RNF4, RBP4, and IGF2 genotypes and their additive genetic effects with litter size in purebred Landrace and Yorkshire sows were studied. The results revealed significant associations between the RNF4 and RBP4 genotypes with the total number of piglets born (TNB) and number of piglets born alive (NBA) traits (P <0.05). The RNF4 CC genotype had greater TNB and NBA than the TT genotype in both breeds. The RBP4 BB genotype had greater TNB and NBA than the AA genotype in the Landrace breed. Significant additive effects of the RNF4 and RBP4 genes on the TNB and NBA were detected (P <0.05). No significant associations of the IGF2 genotypes and their additive effects with any reproductive traits were observed in both Landrace and Yorkshire sows (P >0.05). The results suggested that the RNF4 and RBP4 genes could be useful in selection for increasing TNB and NBA traits in pigs.

The aim of this study was to evaluate the biological efficiency and main bioactive components of three G. lucidum strains, viz. GA1, GA2, and GA3, cultivated in Tam Dao town. The results demonstrated that all strains were capable of growing well on PDA medium supplemented with rice bran. The time required for complete colonization was 9 days. All tested strains of G. lucidum were able to adapt to climate conditions and produce fruiting bodies with satisfactory yield (13-17%), and therefore, they could be considered suitable candidates for commercial cultivation of G. lucidum in Tam Dao. No significant differences in polysaccharide content were observed among all strains. High concentrations of lucidenic N acid (0.33 mg g-1) and ganoderic acid (2.38 mg g-1) were determined in strain GA3. However, the highest ganodermanontriol content was detected in the strain GA1 with 0.3 mg g-1.

Chlorogenic acid is a natural antioxidant that is widespread in the plant kingdom and can be found at a high content level in green coffee beans. This secondary metabolite in green coffee beans has potent biological properties including antioxidant, anti-inflammatory, anti-cancer, anti-obesity, anti-hypertension, and anticonvulsant. In this study, the extraction of chlorogenic acid from Vietnamese green coffee beans was optimized using the response surface methodology. A second-order polynomial model with three important variables (liquid-to-solid ratio, temperature, and extraction time) was used. A rotatable central composite design consisting of 21 experimental runs with three replicates at the center point was applied to describe the experimental data. The experimental results properly conformed to the constructed model (R2 = 0.8549). The optimized conditions were as follows: 40% ethanol (v/v), a liquid-to-solid ratio of 11.77, at 85oC for 64 min. Four extractions were performed in parallel using the optimal conditions to validate the model. The experimental values highly agreed with the predicted value (P <0.05).
