Development of high Protein Nutrition Bar Enriched with Spirulina Plantensis for Undernourished Children
Authors: KUMAR ARVIND , MOHANTY VEDSHREE , YASHASWINI P.
Published: December 2018

This study aimed at incorporating Spirulina in the development of high protein nutrition bars, since protein related malnutrition amongst children is highly prevalent and needs to be addressed diligently. Spirulina, a multicellular filamentous cyanobacteria, has gained popularity as a food supplement for its high macronutrient and micronutrient contents and ease of processing. Spirulina plantensis along with Bengal gram(Cicer arietinum), groundnuts (Arachis hypogaea L.), Cornflakes (Zea mays), and other ingredients was used to make 7 variants of a novel nutrition bar and control sample (without Spirulina).The bars were evaluated for nutritional quality (proximate analysis, antioxidant ability, total phenolic content), textural parameters, colour attributes, and sensory characteristics. The protein content of the bar was found to be 167% more than the control sample. The antioxidant potential and total phenolic content of bars containing Spirulina were substantially higher than the control sample. The textural characteristics displayed by certain variants of the bar did not significantly differ (p>0.05) from the control sample, while the colour of the bar did. The Spirulina enriched bar gained acceptability in terms of sensory attributes, hence was concluded to be a potential product for undernourished children with protein deficiency.

The experience and lessons learnt from the underutilized backyards of landless women make it imperative to create alternate livelihood options. Among them horticultural practices with strict adherence to sustainable technologies will be an everlasting solution. It ensures balanced household consumption of vegetables and fruits in their daily food habits and prevents nutritional maladies. 2552 farm families of Bhumia, Paroja, Kandha and Penthia tribal women of the Kundra Block, Koraput district, Odisha are involved in an organic Annadata Kitchen Garden model in their backyards. It ranges from 5-20 cents covering three seasons in a year. Multiple nutri-crops are grown with an initial investment of Rs 1200 to 2000/-. Till date, 329 such units have been established. It was observed through research that use of organic manure, botanical preparations and Integrated Pest Management tactics could enhance the crop productivity. The landless women not only serve the entire family with nutritious food but also get a reasonable income from the surplus produce. This paper analyzes dietary habits, diversity and household consumption.

Authors: Efimov Alexey Anatolevich , Arsenov Pavel Vladimirovich , Minkov Kirill Nikolaevich , Ivanov Victor Vladimirovich
Published: December 2018

In this paper we investigated the effect of substrate temperature (25-300 °C) on the aspect ratio (thickness/width) of the silver lines formed by aerosol jet printing (AJP). This effect was studied by varying the speed of substrate (50-250 mm/min) and the number of printing layers (1-25 layers) in order to obtain lines with high aspect ratio. It is shown that AJP on a heated substrate at a temperature equal to >100 °C allows to increase the aspect ratio of the lines more than 17 times in comparison with conventional AJP. It is established that the aspect ratio of the lines increases with the increase in the number of printing layers and the decrease in the speed of substrate. Silver lines with high aspect ratio of 1.7 with a width of about 25 μm were formed. This result is important for the formation of current-carrying microcircuits with a high density of elements.

Authors: Jaiswal Deepika , Yadava Sudha
Published: December 2018

Some novel mixed ligand complexes of Mn(III) with glycine ligand namely [Mn(gly)2 Cl(en)], [Mn(gly)2 Br(en)], [Mn(gly)2 N3 (en)] and [Mn(gly)2 NCS(en)] have been synthesized starting from Mn(gly)2 Cl, Mn(gly)2 Br, Mn(gly)2N3 and Mn(gly)2 NCS respectively. These newly synthesized complexes have been characterized by UV/Vis, FT-IR and Mass spectrometry. The spectroscopic data suggest distorted octahedral geometry for all these mixed ligand complexes. The λmax values of these complexes for 5T2g → 5Eg transitions are 482 nm for [Mn(gly)2N3(en)], 488 for [Mn(gly)2NCS(en)], 486 for [Mn(gly)2 Br(en)] and 484 for [Mn(gly)2Cl(en)], all these transitions are red shifted in comparison to their parent complexes. The ligand field parameters such as 10 Dq, B and β have also been calculated and suggest covalent metal ligand bonding. One peculiar finding is that the FT-IR spectra shows frequencies for both free and coordinated NH2 group in all complexes indicating that the ethylenediamine ligand present here is non bridging in nature. The mass spectrometry results show molecular ion peaks at m/z 300, 345, 307 and 323 for [Mn(gly)2Cl(en)], [Mn(gly)2Br(en)], [Mn(gly)2N3(en)] and [Mn(gly)2NCS(en)] respectively. The coordination of ethylenediamine to Mn(III) enhances its efficiency towards decolourization methyl red dye.

Abraham Lincoln’s Second Annual Message to Congress and Public Policy Advocacy for African Colonization
Authors: Southard Bjørn F. Stillion
Published: December 2018

This essay situates Abraham Lincoln’s Second Annual Message within the context of previous discourse on African colonization to illuminate the significance of the text as public policy rhetoric. I argue that Lincoln’s proposal for compensated emancipation and colonization in the Second Annual Message was the apotheosis of colonization advocacy. Lincoln’s argumentation navigated the complicated context to make a final, but failed, case for a compromise between North and South before the Final Emancipation Proclamation took effect.
Longitudinal Changes in Semantic Concreteness in Semantic Variant Primary Progressive Aphasia (svPPA)
Authors: Cousins Katheryn A. Q. , Ash Sharon , Olm Christopher A. , Grossman Murray
Published: December 2018

This study examines longitudinal changes in the concreteness of nouns produced by human patients with semantic variant primary progressive aphasia (svPPA). Cross-sectional studies show that patients with svPPA demonstrate severe loss of concrete noun knowledge linked to atrophy of the left ventral temporal lobe. It is unknown how disease spread and duration affect the magnitude of the concreteness impairment in svPPA. We evaluate longitudinal spoken production of concrete nouns in svPPA, and relate this to changes in longitudinal MRI measures of gray matter (GM). Noun concreteness in svPPA is compared to that of behavioral variant frontotemporal dementia (bvFTD) patients, who typically demonstrate highly concrete speech. We elicited naturalistic speech samples at two time points (time 1 and time 2) in patients with svPPA (n= 11) and bvFTD (n= 15) through descriptions of the Cookie Theft picture and evaluated each spoken noun for concreteness. Compared to bvFTD patients whose noun production remained highly concrete throughout the testing period, mixed-effects models revealed that noun concreteness significantly decreased as disease progressed in svPPA. We also measured longitudinal changes to GM in a subset of svPPA patients (n= 7), who showed significant decline in the left and right temporal and frontal regions. Regression analyses revealed that longitudinal GM atrophy in the right fusiform and parahippocampal gyri and the left superior temporal gyrus was related to decreasing noun concreteness. These results suggest that progressive atrophy of the ventral temporal lobe in svPPA contributes to declining concrete noun production over time.
Prefrontal Theta Oscillations Promote Selective Encoding of Behaviorally Relevant Events

Published: December 2018

The ability to capture the most relevant information from everyday experiences without constantly learning unimportant details is vital to survival and mental health. While decreased activity of the medial prefrontal cortex (mPFC) is associated with failed or inflexible encoding of relevant events in the hippocampus, mechanisms used by the mPFC to discern behavioral relevance of events are not clear. To address this question, we chemogenetically activated excitatory neurons in the mPFC of male rats and examined its impact on local network activity and differential associative learning dependent on the hippocampus. Rats were exposed to two neutral stimuli in two environments whose contingency with an aversive stimulus changed systematically across days. Over 2 weeks of differential and reversal learning, theta band activity began to ramp up toward the expected onset of the aversive stimulus, and this ramping activity tracked the subsequent shift of the set (stimulus modality to environment) predictive of the aversive stimulus. With chemogenetic mPFC activation, the ramping activity emerged within a few sessions of differential learning, which paralleled faster learning and stronger correlations between the ramping activity and conditioned responses. Chemogenetic mPFC activity, however, did not affect the adjustment of ramping activity or behavior during reversal learning or set-shifting, suggesting that the faster learning was not because of a general enhancement of attention, sensory, or motor processing. Thus, the dynamics of the mPFC network activation during events provide a relevance-signaling mechanism through which the mPFC exerts executive control over the encoding of those events in the hippocampus.

Published: December 2018

BACKGROUND AND OBJECTIVES:

Staphylococcus aureus (SA) is the second leading cause of late-onset sepsis among infants in the NICU. Because colonization of nasal mucosa and/or skin frequently precedes invasive infection, decolonization strategies, such as mupirocin application, have been attempted to prevent clinical infection, but data supporting this approach in infants are limited. We conducted a phase 2 multicenter, open-label, randomized trial to assess the safety and efficacy of intranasal plus topical mupirocin in eradicating SA colonization in critically ill infants.

METHODS:

Between April 2014 and May 2016, infants <24 months old in the NICU at 8 study centers underwent serial screening for nasal SA. Colonized infants who met eligibility criteria were randomly assigned to receive 5 days of mupirocin versus no mupirocin to the intranasal, periumbilical, and perianal areas. Mupirocin effects on primary (day 8) and persistent (day 22) decolonization at all three body sites were assessed.

RESULTS:

A total of 155 infants were randomly assigned. Mupirocin was generally well tolerated, but rashes (usually mild and perianal) occurred significantly more often in treated versus untreated infants. Primary decolonization occurred in 62 of 66 (93.9%) treated infants and 3 of 64 (4.7%) control infants (P < .001). Twenty-one of 46 (45.7%) treated infants were persistently decolonized compared with 1 of 48 (2.1%) controls (P < .001).

CONCLUSIONS:

Application of mupirocin to multiple body sites was safe and efficacious in eradicating SA carriage among infants in the NICU; however, after 2 to 3 weeks, many infants who remained hospitalized became recolonized.

Published: December 2018

The Malayan leaf fish or locally named as kepor (Pristolepis grooti) is one of important biotic components in Ranau Lake ecosystems. This study aimed to estimate population dynamic and exploitation rate of kepor in Ranau Lake, South Sumatera. The population parameters are estimated based on length frequency data which were collected in March to October 2013. Growth parameters and fishing mortality rates were calculated using FiSAT software package. The results showed that kepor’s growth was negative allometric, which tended to gain length faster than weight. Kepor population was dominated (42%) by individual length of 10.0 to 11.0 cm. Predicted length infinity (L) was 17.28 cm with high value of growth rates (K) of 1.4 year-1. The natural mortality rate (M) is 2.57 year-1, the fishing mortality rate (F) is 5.36 year-1 and total mortality rate (Z) is 7.93 year-1. The exploitation rate of Malayan leaf fish in Ranau Lake (E = 0.68 year-1) has passed the optimum score.

Authors: Gustiano Rudhy , Prakoso Vitas Atmadi , Ath-thar Muhamad Hunaina Fariduddin
Published: December 2018

Pangasiidae are economically important riverine catfishes that generally exist in freshwater from the Indian subcontinent to the Indonesian Archipelago. Among genera in Pangasiidae, genus Pangasius has numerous species. The objective of the present study is to describe all species of genus Pangasius with their diagnosis and natural distribution. Nine hundred and ninety nine specimens formed the core of the material examined in this study. All examined species were collected from Bangladesh, Vietnam, Cambodia, Thailand, Malaysia, and Indonesia. Additional samples including specimens of 49 previously described species housed in various museums were also examined. On each specimen, 35 point to point measurements covering the possible variation of the body conformation were taken using dial calipers. Measurements were log-transformed before the PCA was run on the covariance matrix. The first factor, considered as the size-factor was not taken into account to minimize the effects of size differences among samples. Allometry is indicated by unequal loading of variables on the first component and by biological interpretation of allometric data proceed using coefficients of the first components against the second components that was linear. An independent PCA was run on the correlation matrix from the untransformed count data. Finally, data analysis consisted in characterizing groups from scatter plots between pairs of structuring characters for subsequent use in generic identification keys. The results show Asian catfish genus Pangasius consist of 21 valid species. This paper describes the diagnosis and distribution of all valid species.
STRUCTURAL ANALYSIS AND RATIONAL DESIGN OF MECHANISMS OF CROSS-ROLL TUBE STRAIGHTENING MACHINES
Authors: Zdanevich S. S. , Pogrebnyak R. P. , Zdanevich S. V.
Published: December 2018

Purpose. The article is aimed to perform a structural analysis of the main and auxiliary mechanisms of tube straightening machines, to identify structural and local redundant links in the mechanism schemes, and to offer recommendations on their rational design. Methodology. The solution is realized by means of the theory of mechanisms and machines using structural analysis of the mechanisms of tube straightening machines based on the universal structural theory of O.G. Ozol. Findings. The extended principle of the machine’s mechanism formation, which provides inclusion to the mechanism not only невільних solid bodies, but also the deformed bodies, allows us to consider the structure of machines for pressure processing of metals, taking into account the plastically deformed workpiece. Therefore, such machines include in their composition a deformed workpiece as an integral part of the machine mechanism, whose deformation and addition of certain geometric parameters to it is the reason the tube straightener was created for. Defects in the machine structure are determined by the local and structural redundant links included in the kinematic chains of the mechanisms, which transform the mechanism into a statically undetermined system. Movement of the mechanism with defects in the structure is possible in the presence of gaps or due to deformation of the links. The main mechanism of the tube straightening machine is a mechanism of variable structure, therefore, an analysis for its two states is carried out: before the tube is caught by the rollers and during its straightening. For calculation of the number of mobilities of the outer «roll – tube» pair, it was taken into consideration that most of the coordinates are overlaid with non-retentive links, which contain a fractional number of constraints. Fifteen redundant links were identified in the main mechanism and their amount in the auxiliary mechanisms of the tube straightening machine was established. Originality. The structural analysis of tube straightening machines with the search for redundant links was never performed. A structural analysis of the mechanisms of cross roll tube straightening machine was performed for the first time, taking into account the presence of external fractional links that are superimposed in the «roll-tube» pairs. Practical value. The practical recommendations for eliminating the harmful redundant links that were found in the structural analysis of the main and auxiliary mechanisms of the tube straightening machine were developed.

This is evidenced both by numerical results and by visualization of the velocity and pressure distributions during the water stream flow around the screw-propeller. For the research, the screw-propellers with different profiling were used. The method using the sector model of the screw-propeller is the most inefficient way of setting the project for simulation of the screw-propeller operation. Originality. The results of the work are the part of the methodology for setting the project in the Flow Vision environment for conducting numerical experiments to simulate the screw-propeller operation in free water. Practical value. It is established that the way of setting the project for simulating the screw-propeller operation in free water using the «sliding» grid boundary condition is the most practical one. The validity of this conclusion is confirmed by the results obtained during large number of numerical experiments on flow around the rotating screw-propeller at a given speed. The universality of such method lies in the possibility of its application during calculation of the propulsion/steering unit, which operates behind the ship hull.

Published: December 2018

Purpose. The research aims at the analysis of the possibility of using in the development of one-group train formation plan the criterion, which allows to consider the costs associated with the movement of cars and locomotives. Methodology. The existing methods for development of train formation plan and current directions of its optimization are analyzed. The formulas for calculating the cost-saving criterion for running cars and locomotives in through-trains have been developed. Findings. The dependence between the service speed and the category of train was analyzed on the examples of railway sections of the Belarusian Railways. The obtained results allowed to conclude that, in general, the service speed of through-trains is higher than that of local trains. At the same time, the traffic intensity and section capacity affect the difference between the service speeds of trains belonging to the different categories. The one-group train formation plan was developed using the traditional methods and the proposed criterion on the example of the railway direction, where four marshalling yards are located. The use of the proposed methodology for the development of train formation plan can provide significant savings in operating costs due to the acceleration of the passing of the car through the railway sections. Originality. The use of the additional parameter in the development of train formation plan – «the criterion of cost saving when running of rolling stock in through-trains» – is proposed. It is shown that the application of this criterion makes it possible to substantiate the creation of separate assignments of some car-streams, while these car-streams would be considered as unprofitable, when using traditional methods of the calculation of train formation plan. The authors analyzed the influence of such factors as the train composition, the length of the railway section and the car traffic volume on the cost savings by using the proposed criterion. Practical value. The obtained results can be used in the development of the train formation plan, which will save the operating costs connected with the movement of cars and locomotives.
ADAPTATION OF THE FELDER-SOLOMAN INDEX OF LEARNING STYLES (ILS) INTO TURKISH AND AN ASSESSMENT OF ITS MEASUREMENT QUALITY
Authors: SENELER Cagla , PETRIE Helen
Published: December 2018

The Index of
Learning Styles (ILS) is a questionnaire (in English) used to measure
preferences of learners on the four dimensions of the Felder-Silverman Learning
Style Model (LSM): Active-Reflective, Sensory-Intuitive, Visual-Verbal, and
Sequential-Global. To make it suitable for Turkish learners and researchers, we
provided a definitive translation of the ILS into Turkish, which we refer to as
the Turkish Index of Learning Styles, (T)ILS. To verify the translation,
multiple forward and back translation techniques were used and four translators
employed. The reliability and validity of the (T)ILS were also checked by
conducting two different test administrations to 63 undergraduate students in
Turkey. The (T)ILS has the highest Cronbach’s alpha and test-retest reliability
values among other studies that have tested its validity and reliability. Besides,
no significant differences were found between mean scores of the two test
administrations. Furthermore, the factor structure gave evidence of construct
validity. Recommendations on further work of (T)ILS are also discussed.
Process-symptom-bridges in psychotherapy: an idiographic network approach
Authors: Kaiser Tim , Laireiter Anton-Rupert
Published: December 2018

Aim: Real-time monitoring of psychotherapeutic processes was recently described as a promising, new way of track-ing periods of change in ongoing treatments. This approach generates complex, multivariate datasets that have to be presented in an intuitive way for clinicians to aid their clinical decision-making. Using network modeling and new approaches in centrality analyses, we examine “bridge nodes” between symptom stress and aspects of the psychotherapeutic process between therapy session (intersession processes, ISP). Method: We recorded intersession processes as well as depressive and anxiety symptoms using daily questionnaires in ten cases. Regularized, thresholded intraindividual dynamic networks were estimated. We applied bridge centrality analysis to identify individual bridges between psychotherapeutic processes and symptoms in the resulting models. Casewise interpretations of bridge centrality values are offered. Results: Bridge centrality analysis revealed individual bridge nodes between intersession processes and symptom severity. Strength and direction of bridges varied substantially across individuals. Conclusion: Given current methodological challenges, idiographic network studies are feasible and offer important insights for psychotherapy process research. In this case, we demonstrated how patients deal with periods of increased symptom stress. In this case we have described how patients deal with their therapy under increased symptom load. Bridges between psychotherapeutic processes and symptom stress are a promising target for monitoring systems based on ISP. Future studies should examine the clinical utility of network-based monitoring and feedback in ongoing therapies. In the near future, process feedback systems based on idiographic models could serve clinicians to improve treatments. Keywords: depression, anxiety, intersession processes, ecological momentary assessment, network analysis
Özel Yetenekli Öğrencilerin Doğal Sayılarla Dört İşlem Gerektiren Problem Kurma Becerilerinin İncelenmesi
Authors: ERDOĞAN Fatma , ERBEN Tuba
Published: December 2018

Bu araştırmada özel yetenekli öğrencilerin doğal sayılarla dört işlem gerektiren problem kurma becerilerinin incelenmesi amaçlanmıştır. Araştırmada, nicel araştırma yöntemlerinden betimsel araştırma modeli kullanılmıştır. Araştırmanın örneklemini, Türkiye’nin Doğu Anadolu Bölgesindeki bir ilde bulunan, bilim ve sanat merkezinde öğrenim görmekte olan 25 ilkokul dördüncü sınıf öğrencisi oluşturmuştur. Araştırmada veri toplama aracı olarak, doğal sayılarla dört işleme yönelik altı maddeden oluşan Problem Kurma Formu kullanılmıştır. Öğrencilerin kurdukları problemler, anlamsal yapılarına göre analiz edilmiştir. Araştırma bulgularına göre, özel yetenekli öğrencilerin doğal sayılarla dört işlem gerektiren farklı anlamsal yapılara sahip problemler kurdukları görülmüştür. Ancak, doğal sayılarla dört işlem türüne göre problemlerde bazı anlamsal yapıların daha sık kullanıldığı belirlenmiştir. Buna göre, özel yetenekli öğrencilerin kurdukları problemlerde, toplamanın birleştirme, çıkarmanın ayırma, çarpmanın tekrarlı toplama, bölmenin ise paylaşma anlamının en sık kullanılan anlamsal yapılar olduğu saptanmıştır. Ayrıca, bazı öğrencilerin problem kurma durumlarında istenilen dört işlemin dışında diğer işlemlere yönelik problem kurma, alıştırma yazma, yanıt verememe, mantık hataları yapma gibi sorunlar yaşadıkları belirlenmiştir. Araştırma bulguları ışığında, özel yetenekli öğrenciler için geliştirilecek farklılaştırılmış matematik dersi öğretim programlarında farklı anlamsal yapılar içeren problem kurma etkinliklerine yer verilmesi önerilmektedir. Daha sonra yapılacak araştırmalarda özel yetenekli öğrencilerin problem kurma becerilerinin yaratıcılık bağlamında incelenmesi önerilmektedir.

Published: December 2018

New indan-1-one derivatives (8 examples) with amino acid fragments were synthesized through the N-acylation of the amino acids by 2-(3-oxo-2,3-dihydro-1H-inden-5-yloxy)acetic acid using the method of activated N-hydroxysuccinimide esters. To obtain corresponding methyl esters (2 examples) two ways were possible: the N-acylation of the amino acid methyl esters by 2-(3-oxo-2,3-dihydro-1-inden-5-yloxy)acetic acid through the activated imidazole derivatives or methylation of the carboxylic function of preformed N-{[(1-oxoindan-6-yl)oxy]acetyl}amino acids.

Published: December 2018

For the purpose of outlining structure-property relationships for two-photon absorption (2PA), a "s-locked" carbo-cyclohexadiene with two fluorenyl substituents has been envisaged for comparison with previously studied aromatic carbo-benzene and non-aromatic carbo-quinoid congeners. A representative where the C10-π-conjugated fluorenyl moieties are also connected by a C8-π-insulating 3,6‐dimethoxy‐3,6‐bis(trifluoromethyl)octa‐1,4,7‐triyn-1,8-diyl edge has thus been synthesized in four steps from known C8F triyne and C10 triynyldial, through a [8F+10] cyclization process. In spite of a relatively strong absorbance (e = 84 800 L.mol-1.cm-1 at 634 nm), the non-vanishing green fluorescence (at 533 nm) of the chromophore should allow measurements of the 2PA cross section by both the TPEF and Z-scan methods.

Authors: Kononova A.P. , Pugovkina O.D.
Published: December 2018

The article presents the results of the validation of the Tendency To Forgive and Attitudes Towards Forgiveness Scale on a Russian sample which included 366 healthy adult participants. The questionnaire is based on R. Enright’s cognitive model of forgiveness, in which the ability to forgive is determined by the social cognition quality (awareness of one’s own emotions and emotion self-regulation and empathy towards the offender). The study established plausible reliability of both scales. Confirmatory factor analysis was also conducted. The authors analyzed correlations of the tendency to forgive and attitudes towards forgiveness with indicators of emotional ill-being, social cognition, quality of life, life satisfaction, and a number of personal traits (such as Machiavellianism and the Big Five: extraversion, conscientiousness, agreeableness, neuroticism, openness to experience). The results are discussed in the context of adaptive versus maladaptive aspects of forgiveness, as well as in the context of the psychological basis of adaptive ability to forgive.

Published: December 2018

The paper presents the results of a study of the structural features of personal changes of student-actors in the process of studying in the theater college. We hypothesize that at the stage of primary occupation selection and in the training process students aquire and develop specific stable personality structures (association of personal qualities), which are essential for the formation of the subject of acting. The sample consisted of 832 respondent: 686 enrollees of theater college; 188 students at the beginning and 174 — at the end of the 1st year, 106 2nd year, 91 3rd year, and 68 4th year students. Methods: R. Cattell Personality Factors test (16 PF). Results: four invariant factors describing the structural features of the personality of student-actors are identified — personal anxiety, the desire for public communication, emotional impact on the other, individualism. Conclusions: the hypothesis of the presence of stable personality structures was confirmed, a number of essential personal features that contribute to the implementation of stage communication between self, role, and viewer were found.
