Published: May 2018

Background

Essential oils, infusion and decoction extracts of Calamintha nepeta L. were evaluated for their bioactive substances (polyphenols and essential oils) and antioxidant activities.

Methods

The amounts of phenolic compounds were determined by colorimetric assays and identified by high performance and liquid chromatography coupled with ultraviolet detector (HPLC-UV) method. The chemical composition of essential oils was determined by gas-chromatography coupled with mass spectrometry (GC/MS) method. For the evaluation of the antioxidant activity of essential oils and extracts, two different assays (reducing power and DPPH radical scavenging activity) were used.

Results

Infusion extract presented the highest phenolic content, followed by the decoction one, while the lowest amount was observed in essential oils. The amount of flavonoids of the decocted extract was higher than that of the infused one. The phenolic profile of C. nepeta infusion and decoction extracts revealed the presence of 28 and 13 peaks, respectively. Four phenolics compounds were identified in infusion (gallic acid (GA), rosmarinic acid (RA), caffeine (C) and caffeic acid (CA)) and two were identified in decoction (GA and RA). The chemical composition of essential oils revealed the presence of 29 compounds, accounting for the 99.7% of the total oils. Major compounds of essential oil (EO) were trans-menthone (50.06%) and pulegone (33.46%). Infusion and decoction extracts revealed an interesting antioxidant activity which correlates positively with their total phenolic contents.

Conclusions

These results showed that Calamintha nepeta could be considered as a valuable source of phenolics and essential oils with potent antioxidant activity.

Authors: Brizitskii Roman V. , Saritskaya Zhanna Y.
Published: May 2018

The inverse coefficient problem for the nonlinear
convection-diffusion-reaction equation is considered.
A velocity vector and a mass-transfer coefficient are considered as the unknown coefficients and are recovered with the help of the
additional information about the boundary value problem’s solution.
The inverse coefficient problem is reduced to a two-parameter problem of multiplicative control,
the solvability of which is proved in a general form.
For a cubic reaction coefficient the local stability estimates of the control problem’s solutions
are obtained regarding to a rather small perturbation of either the cost functional or
the specified functions of the boundary value problem.
Soliton Pulse Generation for WDM-Based Free Space Optics Communication Using Microring Resonators
Authors: Shahidinejad Ali
Published: May 2018

A microring resonator (MRR) and an add/drop devices are presented to generate picosecond solitonic pulse and signal as multichannel localized wavelengths, applicable for WDM-based free space optics (FSO) communication. A Gaussian pulse is inputted to the first ring resonator of the proposed system. Because of the nonlinear Kerr effect, chaotic signals are created. The second MRR filters the generated signals and shape solitonic pulses, where the accurate FWHM of 20 ps with intensity of 2.45 W are obtained. The add/drop device is applied for tuning the solitonic pulses. Results indicate that a range of solitonic wavelengths from 1550 nm to 1600 nm are obtained, where FSR and FWHM are 144 pm and 5 pm, respectively. Finally, performance of the proposed MRR system is evaluated in terms of bit error rate (BER) and Q factor. In the analysis, the proposed solitonic pulse is compared to conventional counterparts. Using the proposed MRR system, BER and Q factor of WDM-based FSO are considerably improved.

Published: May 2018

This paper introduces a novel code called two dimensional Pascal’s triangle zero cross correlation (2D-PTZCC) for spectral/spatial coding with its structure of the corresponding system to implement in spectral amplitude coding optical code division multiple access (SAC-OCDMA) systems The novel code is derived from a one dimensional zero cross correlation (1D-ZCC) code using Pascal’s triangle rule. The analytical results prove that the proposed code has totally removed the multiple access interference (MAI), in addition the phase induced intensity noise (PIIN) influence is highly reduced due to the zero cross correlation (ZCC) property. Comparing with the recent developed two-dimensional codes like 2D multi diagonal (2D-MD), 2D dynamic cyclic shift (2D-DCS), 2D diluted perfect difference (2D-DPD) and 2D perfect difference (2D-PD) codes for the same code length. The results of simulation show that the suggested code improve the system capacity and increase the number of simultaneous users reaches 29 % and 64 % comparing to 2D-DPD and 2D-PD codes, respectively. As well, it supplies higher signal power and data bit rates whereas it saves effective source power around −0.81dBm for 2D-DCS and 2D-DPD codes and consumes minor light spectral width.

Published: May 2018

Background

Recent studies have discussed the application of wrist circumference as an easy-to-use predictor of general and abdominal obesity. The aim of the current study is to evaluate the association of wrist circumference with generalized and abdominal obesity and to determine its sex- and age-specific optimal cutoff points in association with generalized and abdominal obesity in a national sample of pediatric population.

Methods

This nationwide survey was conducted among 14,880 students, aged 6–18 years, selected through a multistage, random cluster sampling method from rural and urban areas of 30 provinces in Iran from 2011 to 2012. Anthropometric indices (weight, height, wrist circumference, waist circumference [WC], hip circumference [HC]) were measured by standard protocols using calibrated instruments. Body mass index (BMI) and waist-to-height ratio (WHtR) were calculated. By considering the area under the curve (AUC) of the receiver operator characteristic (ROC) curves, we evaluated the association of wrist circumference with obesity indices and determined its sex- and age-specific optimal cutoff points in association with obesity. AUC: 0.5, AUC: 0.5–0.65 and AUC: 0.65–1.0 were interpreted as equal to chance, moderately and highly accurate tests, respectively.

Results

Overall, 13,486 children and adolescents with a mean age of 12.47±3.36 years completed the study (participation rate of 90.6%). In both genders, wrist circumference had a significant correlation with anthropometric measures including weight, height, BMI, WC, HC and WHtR. In all age groups and both genders, wrist circumference performed relatively well in classifying individuals into overweight (AUC: 0.67–0.75, p<0.001), generalized obesity (AUC: 0.81–0.85, p<0.001) and abdominal obesity (AUC: 0.82–0.87, p<0.001).

Conclusions

Wrist circumference is suggested to be a useful index for assessing excess weight in the pediatric age group. Its easy measurement without the need of calculation ratios might make it as a routine measurement in daily clinical practice and in large epidemiological studies.
Is the hemolysis index always suitable for monitoring phlebotomy performance?
Authors: Lippi Giuseppe , Mattiuzzi Camilla , Cadamuro Janne
Published: May 2018

The new generation of clinical chemistry and coagulation analyzers is equipped with technical features allowing a systematic check of sample quality, including an assessment of the so-called HIL (“hemolysis”, “icterus”, “lipemia”) indices. These measures enable an accurate and reproducible assessment of sample hemolysis in serum or plasma, hence the hemolysis index (H-index) is now also increasingly used for monitoring and benchmarking phlebotomy performance. Reliable evidence attests that intravascular hemolysis is not such a rare phenomenon, and its prevalence may be especially higher in geographical areas where congenital hemolytic diseases are endemic, as well as in healthcare settings where patients with acquired hemolytic disorders are more frequently visited or hospitalized. It is hence conceivable that monitoring phlebotomy performance based on the rate of hemolyzed specimens received by the laboratory may not be so straightforward, provided that specimens drawn from patients with intravascular hemolysis can be identified and excluded from the analysis. The aim of this article is to provide an overview of potential drawbacks in using the H-index alone for monitoring phlebotomy performance, and to offer potential solutions to improve its efficiency for this scope. We therefore suggest that the H-index may only be used for purposes of benchmarking phlebotomy performance when the overall number of diagnoses of hemolytic diseases or the haptoglobin values measured by the laboratories are comparable across different healthcare settings or geographic areas.
Growth suppression of glioma cells using HDAC6 inhibitor, tubacin
Authors: Yin Changjiang , Li Pibao
Published: May 2018

In cancer research, autophagy has been revealed as one of the major ways to maintain the metabolism of cancer cells, including glioma cells, through protein degradation. Meanwhile, autophagy is also regarded as a kind of mechanism to protect glioma cells from a harmful stimulus, such as chemical and radiation treatment. So, the inhibition of autophagy may be very helpful in curing glioma. This study aimed to determine the effect of autophagic inhibition on glioma cells using tubacin, a specific inhibitor of histone deacetylase 6(HDAC6). According to the results, tubacin inhibited the growth of both U251 and LN229 cells, which was accompanied by lower HDAC6 activity and accumulated autophagosome. The inhibition of HDCA6 also led to accumulation of autophagosome and death of glioma cells. Moreover, the combined treatment of tubacin and temozolomide, an alkylating agent used to treat glioblastoma, induced more severe glioma cell death. Thus, it can be concluded that inhibition of HDAC6 suppressed growth and drug resistance of glioma cells in-vitro through autophagic suppression and blocking of fusion of autophagosome and lysosome.

TMP properties and refining conditions in a CD82 chip refiner. Part I: Step changes of process variables, description of the tests
Authors: Ferritsius Rita , Ferritsius Olof , Hill Jan , Karlström Anders , Eriksson Karin
Published: May 2018

The study explores how changes in process variables, residence time and pulp consistency in refining influence the pulp properties. The equipment utilized in this study was a conical disc chip refiner (RGP82CD) producing thermomechanical pulp (TMP). The focus was on the ratio between tensile index and specific energy consumption. Pulp properties were measured for composite pulp samples taken from the refiner blow line. Residence times and pulp consistencies were estimated by use of the extended entropy model. This showed that the CD-refiner, with the flat and conical refining zone, has a process performance similar to that of a two-stage refiner set-up, and that the consistency in both refining zones is of high importance. Comparing different periods revealed that even if the values of measured blow line consistency are similar, significant differences in the estimated consistency in the flat zone can prevail. Therefore, only monitoring blow line consistency is not enough. Specifically, it was found that the pulp consistency after the flat zone could be very high, considerably higher than in the blow line, and this could have negative effects on tensile index and fibre length.
Impact of non-uniform water absorption on water-interference print mottle in offset printing
Authors: Thorman Sofia , Ström Göran , Gane Patrick A. C.
Published: May 2018

Print mottle is a serious and yet common print defect in offset printing. An imbalance between the feed of fountain solution and the ability of the paper substrate to absorb and transport this water away from the surface can cause moisture/water interference problems. In the study presented here, we have investigated the uniformity of aqueous absorption and coating structure of pilot-coated papers with different types and dosages of dispersants and linked this to print mottle and uncovered areas (UCA). In earlier studies, the print quality of these papers indicated that a moderate addition of excess dispersant caused ink refusal, ink-lift-off (ink-surface adhesion failure) and water-interference mottle when printing at elevated fountain feed. In the present study, we have shown that a majority of the samples with uneven water/moisture absorption and an uneven burn-out reflectance tended to have more severe printing problems related to surface-moisture/water.An aqueous staining technique was used to characterise the absorption non-uniformities. This method has been developed previously with focus on absorption of flexographic water-based inks but can clearly give relevant information also for offset printing, when it comes to moisture/water interference mottle.
Improved Propagation Techniques to Enhance the Productivity of Banana (Musa spp.)
Authors: Tumuhimbise Robooni , Talengera David
Published: May 2018

The objective of this article is to provide information on pertinent propagation techniques for increased banana productivity. Banana, a very important crop in many tropical and subtropical countries of the world, is propagated with extreme difficulties. Its ordinary propagation technique of using suckers directly detached from a mother plant is limited by low multiplication rates and propensity of disseminating pests and diseases, which culminates in reduced banana productivity. Improved propagation techniques such as mother plant stripping, decapitation and mini-corms that increase the number of suckers are also somewhat deficient for large scale seed production and quality. Consequently, tissue and cell culture methods have been developed to address some of the challenges of seed quantity and quality although they are yet to be widely adopted. In this detailed review that includes results from hard-to-find literature, we discuss the traditional and modern methods of banana propagation, their benefits and limitations. Specifically, tissue culture stands out as the most prolific method of delivering high quantity and quality seed in banana. Its applicability, however, is limited by high costs of production and a need for skilled personnel and specialized equipment. It is imperative that to build a sustainable and viable banana seed production system, a multiplication scheme that combines two or more multiplication methods including tissue culture for cleaning the seed stock is utilized. The information provided gives premise for interventions to alleviate the problems of low banana seed availability, quantity and quality.
When “Questions“ are not Questions. Inferences and Conventionalization in Spanish But-Prefaced Partial Interrogatives
Authors: Ehmer Oliver , Rosemeyer Malte
Published: May 2018

The present paper analyzes the discourse-pragmatic function of introducing Spanish qué ‘what’- interrogatives with the concessive connective pero ‘but’. In some contexts, a pero-preface contributes to the interpretation of the interrogative as the realization of an interactional challenge rather than a request for information (e.g. an information question). We explore the inferential processes by which the peropreface leads to an interpretation of the interrogative as an interactional challenge and try to demonstrate that this challenge function of pero-prefaced qué-interrogatives may not only achieved ‘ad hoc’ by a local combination of the constitutive elements, but also by conventionalized form-function associations that developed diachronically. In a first step, we analyze pero-prefaced qué-interrogatives in a corpus of spoken Present Day Spanish. There are three main functions of pero-prefaces: to signal that a previous answer to the same interrogative is insufficient, to insist on an answer to a previously unattended request, or to challenge an immediately preceding action by an interlocutor. Using methodology from variationist linguistics, we identify entrenched patterns of pero-prefaced qué-interrogatives that have conventionalized the challenge function. In a second step, we conduct a diachronic variationist analysis of the development of Spanish pero-prefaced qué-interrogatives between 1700 and 1975, testing the hypothesis that the challenge reading developed later than the question reading. Our results show that due to their largely monological nature, the same inferential processes cued by pero lead to different discourse functions in historical texts. Over time, however, the use of pero-prefaced interrogatives started to become more likely in constructed dialogues. We argue that this change reflects an ongoing conventionalization of the challenge function in pero-prefaced interrogatives in spoken language.
Investigating Inferences in Sequences of Action: The Case of Claiming “Just-Now” Recollection with Oh That’s Right
Authors: Küttner Uwe-A.
Published: May 2018

This paper offers an exploratory Interactional Linguistic account of the role that inferences play in episodes of ordinary conversational interaction. To this end, it systematically reconsiders the conversational practice of using the lexico-syntactic format oh that’s right to implicitly claim “just-now” recollection of something previously known, but momentarily confused or forgotten. The analyses reveal that this practice typically occurs as part of a larger sequential pattern that the participants orient to and which serves as a procedure for dealing with, and generating an account for, one participant’s production of an inapposite action. As will be shown, the instantiation and progressive realization of this sequential procedure requires local inferential work from the participants. While some facets of this inferential work appear to be shaped by the particular context of the ongoing interaction, others are integral to the workings of the sequence as such. Moreover, the analyses suggest that participants’ understanding of oh that’s right as embodying an implicit memory claim rests on an inference which is based on a kind of semanticpragmatic compositionality. The paper thus illustrates how inferences in conversational interaction can be systematically studied and points to the merits of combining an interactional and a linguistic perspective.
Determination of uranium and thorium concentrations in thorium ore sample using artificial neural network and comparison with net area peak method
Authors: Islami rad Seyedeh Zahra , Peyvandi Reza Gholipour
Published: May 2018

In order to determine favorable and different elements in soil, the rapid and accurate methods are required. In this research, simultaneous prediction of thorium and uranium in soil samples was performed via gamma spectrometry. Then, the acquired data were analyzed with artificial neural network (ANN) and net area peak (NAP). Natural soil samples obtained from thorium ore consisting of thorium and uranium were used to train models (ANN and NAP). The techniques were evaluated with respect to prediction ability of uranium and thorium concentrations and robustness. Using proposed ANN and NAP methods, the thorium concentration was predicted with mean relative error percentage less than 8.27% and 9.30%, respectively. Also, uranium concentration just was determined with ANN because the NAP method cannot measure uranium concentration. The performance of the neural network model and NAP technique were compared with the acquired empirical data. The results showed that the neural network can more accurately predict the thorium and uranium concentrations in soil samples.
Adsorptive extraction of uranium (VI) from seawater using dihydroimidazole functionalized multiwalled carbon nanotubes
Authors: Tian Kun , Wu Jinling , Wang Jianlong
Published: May 2018

The adsorptive extraction of uranium (VI) was investigated using multiwalled carbon nanotubes functionalized with dihydroimidazole (DIM-MWCNTs). Dihydroimidazole was grafted onto the surface of MWCNTs via silane coupling agent, N-(3-triethoxysilylpropyl)-4,5-dihydroimidazole. The new adsorbent was characterized using Fourier transform infrared, scanning electron microscope and X-ray Photoelectron Spectroscopy. DIM-MWCNTs were compared with MWCNTs and amidoxime modified MWCNTs (AO-MWCNTs) for uranium adsorption under seawater conditions. The adsorption capacity of uranium onto DIM-MWCNTs was 54.9 mg g−1 at 298 K, which was about 4 times of MWCNTs and similar to that of AO-MWCNTs. Compared with AO-MWCNTs, DIM-MWCNTs were more suitable for seawater pH, and less affected by vanadium. Although DIM-MWCNTs were more affected by carbonate than AO-MWCNTs, DIM-MWCNTs maintained a higher adsorption capacity than AO-MWCNTs due to its alkali resistance. Pyridine-like nitrogen (CH=N–CH) contributed to the adsorption of uranium. The results suggested that DIM-MWCNTs were a potential effective adsorbent for the separation of uranium under seawater condition.

A multivariate regime-switching GARCH model with an application to global stock market and real estate equity returns
Authors: Haas Markus , Liu Ji-Chun
Published: May 2018

We consider a multivariate Markov-switching GARCH model which allows for regime-specific volatility dynamics, leverage effects, and correlation structures. Conditions for stationarity and expressions for the moments of the process are derived. A Lagrange Multiplier test against misspecification of the within-regime correlation dynamics is proposed, and a simple recursion for multi-step-ahead conditional covariance matrices is deduced. We use this methodology to model the dynamics of the joint distribution of global stock market and real estate equity returns. The empirical analysis highlights the importance of the conditional distribution in Markov-switching time series models. Specifications with Student’s t innovations dominate their Gaussian counterparts both in- and out-of-sample. The dominating specification appears to be a two-regime Student’s t process with correlations which are higher in the turbulent (high-volatility) regime.

Das frühste Amduat-Exemplar im Tal der Könige
Authors: Abdel Ghany Khaled
Published: May 2018

After G. Daressy had indicated in the Catalogue général that two small mud-plaster fragments of Amduat (CG 24990 C) were found in the tomb of king Thutmosis I (KV 38), egyptologists assumed that the tomb KV 38 may have been originally decorated with a mud-plaster version of Amduat – however, there were neither archaeological evidences nor illustrations available. For this reason in 2015 I started an exploration in the tomb KV 38. In this search, I actually found further mud-plaster fragments of the Amduat book in the small side chamber (Ja). After examination and analysis of the discovered fragments with comparable scenes from the tomb of Thutmose III (KV 34) I think that the mud-plaster fragment scenes from the tomb of Thutmosis I (KV 38) are much earlier than the similar scenes from the tomb of Thutmosis III. Therefore, the discovered mud-plaster Amduat fragments from the tomb KV 38 represent the earliest ever Amduat specimen in the Valley of the Kings, made by the King Thutmosis I.

Zur Komposition von insofern als im Deutschen
Authors: Bücking Sebastian
Published: May 2018

This paper is about the compositional interpretation of adverbial clauses as introduced by insofern
als (lit. ‘insofar as’) in German (= IAs); for example, Die Lösung ist insofern attraktiv, als sie günstig ist.
(lit. ‘The solution is insofar attractive as it is cheap.’). I argue that IAs always contribute dimensional restrictions, but
do so in two distinct structure-sensitive ways: IAs can be structurally integrated into their host clauses and, thus,
dimensionally specify a lexical component of the matrix VP (= LIAs) (‘The solution is attractive in price.’); alternatively,
they can be structurally non-integrated and, thus, provide a dimension against which the matrix sentence is evaluated
holistically (= SIAs) (‘In light of the fact that the solution is cheap, one may say that it is attrac­tive.’). The proposal
is supported by both syntactic and semantic-pragmatic evidence: (i) LIAs and SIAs are distinguished by independently
motivated tests for structural (non)integration such as scope of negation and particles, focus-background structure, and
variable binding. (ii) LIAs are sensitive to a lexically given multidimensional matrix predication. SIAs, by contrast, require
that the embedded clause specify an objective justification for the truth of the matrix proposition as a whole. In particular,
IAs are shown to not pass tests for subjectivity as discussed for finden (‘find’); for example, judge-
dependency, resistance against denial, or, accessibility of a subjective attitude. The paper concludes by sketching a
formal derivation of both readings. Accordingly, LIAs constrain the dimensional parameter of multidimensional lexical
predications, while SIAs provide facts that de re justify the assertibility of predications for topic situations.
The allotwinning of KCa3Te5O12Cl3: an OD interpretation
Authors: Larvor Carla , Stöger Berthold , Weil Matthias
Published: May 2018

The crystal structure of the oxotellurate(IV) chloride KCa3Te5O12Cl3 is built up of [KTe5O12]3− layers sandwiched by layers of Cl− and Ca2+ ions. The structure can be considered as a twelvefold superstructure with occupational modulation of the K/Te positions. The electron lone-pairs of the Te(IV) atoms are directed towards the free space of the chloride layers. KCa3Te5O12Cl3 can be described as a category III order-disorder (OD) structure in terms of polar layers of one kind. The crystals under investigation are built up of the two polytypes of a maximum degree of order (MDO) with isomorphic C2/c and I2/a symmetry, both of which appear in two orientations. Two data reduction approaches, using either a reciprocal superlattice or three independent domains, were performed and the resulting refinements are comparatively discussed.

Complex1possesses a three-fold interpenetrating network based on layers with a 4-connected sql topology. Complex2is a layered framework constructed by the oba anions and 3-bpcd ligands, which represents a binodal (3,4)-connected {62.10}{6} topology. The adjacent layers of complex2are further linked by hydrogen bonding interactions to build a three-dimensional supramolecular architecture. The differences of metal ions in coordination modes show a significant effect on the final structures of the Zn(II)/Cd(II) complexes. The photocatalytic activities and the fluorescence sensing properties of complexes1and2were investigated.

A significant minority of people with Intellectual Developmental Disorder (IDD) may come into contact with the criminal justice system as a result of criminal behaviours, and many of these who are deemed Unfit to stand trial or Not Criminally Responsible (NCR) will be transferred to forensic psychiatric facilities. Although the perception is that the frequency is increasing, the exact number is unclear, prompting us to conduct a provisional survey of forensic facilities across the province of Ontario to determine (i) point prevalence of IDD and (ii) the characteristics of such individuals. Detainees with IDD were identified in forensic mental health facilities across the Province of Ontario, and information was collected regarding their demographics, characteristics of their index offence and length of stay. We calculated a point prevalence (December 2012) of 19%, and identified that individuals with IDD stayed, on average, longer in these facilities than their non-IDD peers. We argue for the need to set up a working group to begin to address forensic care pathways for adults with IDD

Angelino, D, McCabe, TJG, and Earp, JE. Comparing acceleration and change of direction ability between backpedal and cross-over run techniques for use in American football. J Strength Cond Res 35(1): 47–55, 2021—In American football, defensive backs guard receivers using either cross-over (CO) run or backpedal (BP) techniques, but the efficacy of these techniques is unknown. The purpose of this study was to compare linear acceleration (LA) and change of direction (CoD) ability when using CO and BP. Collegiate football defensive backs participated in LA (n = 13) and CoD (n = 7) testing. During LA, subjects performed CO, BP, and forward sprints with split times taken between 0–3 and 3–5 yd and ground reaction forces recorded 0 and 3 yd from the start. During CoD testing, subjects performed the CO or BP for 3 yd and then were given a cue to sprint to a gate 5 yd away in 1 of 4 directions (downfield, midfield, sideline, or upfield). In LA, CO was faster than BP between 0–3 yd (Δ −0.20 ± 0.02 seconds, p = 0.000) and 3–5 yd (Δ −0.12 ± 0.02 seconds, p = 0.000). At the start of the movement, CO demonstrated greater propulsive forces (p = 0.017). However, 3 yd from the start, CO demonstrated greater propulsive forces and reduced braking forces (p = 0.000 & 0.003). In CoD, CO was faster than BP when running in the downfield (Δ 0.21 ± 0.05 seconds, p = 0.044) and lateral directions (Δ 0.21 ± 0.08 seconds, p = 0.035), but similar in the upfield direction (Δ 0.01 ± 0.08, p = 0.986). Our results indicate that CO is superior to BP in LA, CoD ability, and movement efficiency and support the use of CO for defensive backs.
A Pragmatic View of Disturbed Self-Reflection in Personality Disorders: Implications for Psychotherapy
Authors: Dimaggio Giancarlo , Lysaker Paul H.
Published: May 2018

Patients with personality disorders suffer from impairment in self-reflective capacities. This is not a matter of making incorrect judgments about self-experience but reflects problems with (a) labeling internal experience consistent with the type and level of bodily arousal, (b) seeing how thoughts and feelings are connected to one another within the flow of daily life, and (c) realizing that one's own ideas about interpersonal relationships are subjective and fallible and not direct perceptions of external reality. The authors offer a discussion and definition of each of these three impairments and then offer suggestions for how to address these impairments in psychotherapy.
The emergence of the nicotinamide riboside kinases in the regulation of NAD+ metabolism
Authors: Fletcher Rachel S , Lavery Gareth G
Published: May 2018

The concept of replenishing or elevating NAD+availability to combat metabolic disease and ageing is an area of intense research. This has led to a need to define the endogenous regulatory pathways and mechanisms cells and tissues utilise to maximise NAD+availability such that strategies to intervene in the clinical setting are able to be fully realised. This review discusses the importance of different salvage pathways involved in metabolising the vitamin B3 class of NAD+precursor molecules, with a particular focus on the recently identified nicotinamide riboside kinase pathway at both a tissue-specific and systemic level.

Estrogen treatment has positive effects on the skeleton, and we have shown that estrogen receptor alpha (ERα) expression in cells of hematopoietic origin contributes to a normal estrogen treatment response in bone tissue. T lymphocytes are implicated in the estrogenic regulation of bone mass, but it is not known whether T lymphocytes are direct estrogen target cells. Therefore, the aim of this study was to determine the importance of ERα expression in T lymphocytes for the estrogenic regulation of the skeleton using female mice lacking ERα expression specifically in T lymphocytes (Lck-ERα−/−) and ERαflox/floxlittermate (control) mice. Deletion of ERα expression in T lymphocytes did not affect bone mineral density (BMD) in sham-operated Lck-ERα−/−compared to control mice, and ovariectomy (ovx) resulted in a similar decrease in BMD in control and Lck-ERα−/−mice compared to sham-operated mice. Furthermore, estrogen treatment of ovx Lck-ERα−/−led to an increased BMD that was indistinguishable from the increase seen after estrogen treatment of ovx control mice. Detailed analysis of both the appendicular (femur) and axial (vertebrae) skeleton showed that both trabecular and cortical bone parameters responded to a similar extent regardless of the presence of ERα in T lymphocytes. In conclusion, ERα expression in T lymphocytes is dispensable for normal estrogenic regulation of bone mass in female mice.
Left Atrial Roof Incision for Mitral Valve Interventions and Left Atrial Mass Resection: A Safe Alternative for Excellent Exposure. A Single Center Experience
Authors: Ahmed Ahmed Fouad , Abd Al Jawad Mohammed Nabil
Published: May 2018

Background: Proper visualization has always been the cornerstone for conducting proper cardiac interventions. Although many incisions have been described for mitral valve exposure, the feasibility of some comes at the expense of proper exposure. When it comes to a small left atrium, larger incisions may venture into critically situated structures, creating a heavy toll of increased morbidity and mortality. We aim to evaluate the safety and efficacy of a superior left atrium approach for mitral valve interventions and left atrial mass resection, particularly in a small left atrium.Methods: We present our experience and early results as a retrospective study conducted at Cardiothoracic Surgery Department, Ain-Shams University, Cairo, Egypt. A total of 85 patients underwent mitral valve interventions and left atrial mass resection through limited incision in the left atrial dome.Results: The study included 29 female patients and 56 male patients with a mean age of 42.56 ± 7.39 years. Twenty-seven patients were NYHA class I-II and 58 patients were class III-IV. Mean ejection fraction was 55.47 ± 8.56. Three patients had mitral valve repair, 67 patients had mitral valve replacement, and 15 patients had resection of left atrial myxomas. Preoperative atrial fibrillation was present in 27% of the patients. Two patients had new incidence of atrial fibrillation, one patient had new atrial flutter, and one patient had complete heart block, requiring a permanent pacemaker. No mortality occurred in the series, and three patients needed re-exploration for bleeding.Conclusions: Limited left atrial roof incision provides a safe and feasible exposure for conducting mitral valve interventions and resection of left atrial masses, especially in cases with a small left atrium.

A trabalho teve como objetivo compreender o processo de comunicação dos impactos socioambientais no EIA e como essas informações são repassadas para o Rima, por meio de um estudo comparativo entre as peças técnicas das hidrelétricas de Estreito e São Salvador. Para um melhor compreensão dos dados analisados, a pesquisa categorizou o material e trabalhou com duas frentes: a pesquisa qualitativa, por meio de inferências sobre o texto, e a pesquisa quantitativa, contabilização dos impactos, citações, comparações com outras hidrelétricas e/ou menções a elas e espaço destinado. Com os dados obtidos, observou-se que os estudos e os relatórios de cada uma das hidrelétricas são distintos entre si; que os dois EIAs, apesar de diferentes, possuêm informações técnicas insuficientes; e que os dois Rimas não cumprem o exigido por Resolução e Constituição – a transparência total na comunicação com a população local em torno de grandes empreendimentos.

Published: May 2018

O trabalho trata da mobilização da teoria da reciprocidade e da análise de redes sociais aplicadas ao estudo e à promoção de dinâmicas territoriais locais, entre atores individuais, coletivos e institucionais. A teoria da reciprocidade permite qualificar as relações e interações estruturantes entre atores, grupos sociais e instituições, tanto no plano do real, como do simbólico (linguagem, discurso e aprendizagem) e do imaginário (representações, ideologias). As redes sócio técnicas, inicialmente mobilizadas para a construção da inovação, a circulação de conhecimentos e de recursos, associam aos atores humanos, entidades não humanas: objetos, dispositivos. O estudo de caso examina a aplicação desses métodos a dinâmicas de desenvolvimento rural local no Agreste do Estado da Paraíba no Nordeste do Brasil.
Spillovers Espaciais no desenvolvimento educacional dos municípios da Amazônia Clássica Brasileira

As políticas públicas educacionais aplicadas na Amazônia Clássica brasileira permitiram mudanças nas cidades da região de forma geral. Com isso, esse trabalho buscou verificar a existência de spillovers educacionais2 nos municípios da Amazônia Clássica do Brasil. Traçou como objetivos: identificar padrões espaciais de desenvolvimento educacional entre os municípios; b) detectar a existência de relacionamento espacial entre variáveis socioeconômicas e o crescimento do nível educacional e; c) evidenciar os efeitos diretos e indiretos de variáveis socioeconômicas sobre o crescimento do nível educacional dos municípios do norte brasileiro. Para isso, foi utilizada a metodologia de análise exploratória de dados espaciais e estimação de modelos espaciais, por meio da qual verificou-se que a taxa de pobreza, a taxa de analfabetismo e a taxa de trabalho infantil dos municípios impactam diretamente, mas de forma negativa no desenvolvimento das próprias cidades. Esses efeitos também transbordam para cidades vizinhas, confirmando a presença de spillovers educacionais e a necessidade de se pensar em políticas públicas educacionais de forma regionalizada visando à diminuição da pobreza, do trabalho infantil e a promoção da educação aos analfabetos.
Categorias de Análise da Economia dos Custos de Transação na Decisão de Inovar
Authors: De Oliveira Gabriel Nunes , Arbage Alessandro Porporatti , Costa Nilson Luiz
Published: May 2018

Este artigo foi produzido a partir de tese apresentada ao PPGExR e discute variáveis que influenciam o processo decisório de vinicultores e viticultores da Vitivinicultura da Serra Gaúcha, mais especificamente da APROMONTES (Associação de Produtores dos Vinhos dos Altos Montes), no processo de adoção de inovações capazes de incrementar sua competitividade. Para discutir esse processo decisório, utilizamos como embasamento teórico particularmente a Economia dos Custos de Transação. Consideramos que os custos de transação são os custos que os agentes enfrentam toda vez que se estabelecem trocas comerciais e possuem natureza distinta dos custos de produção (MARAGNO, 2007). Tratam-se dos custos de negociar, além dos custos de redigir (ex-ante) e garantir o cumprimento de determinado contrato (ex-post). A coleta de dados foi realizada por meio de entrevistas com doze vinícolas, 25 viticultores ligados a cada uma das vinícolas integrantes da APROMONTES, e, como testemunhas, sete viticultores integrantes do STR (Sindicato dos Trabalhadores Rurais de Flores da Cunha e Nova Pádua). A análise dos resultados parece apontar para o fato de que as vinícolas possuem certo grau de especificidade de ativos. No entanto, é em nível de viticultor que ela se apresenta mais traumática, pois as especificidades de relevo e de clima alcançadas às terras da região limitam a migração para outras atividades, caracterizando o que Williamson (1996) trata por especificidade do tipo física e que se refere à adequação de partes a um tipo de produto. Também foi verificada a presença de uma dimensão de especificidades de ativo humana, a qual denominamos de afetiva, que emerge do vínculo do “indivíduo” com seu objeto de produção (parreira) e também dos relacionamentos com seus pares.
A teoria de Amartya Sen: uma aplicação da abordagem das capacitações e da ideia de justiça à evolução do mercado nacional de trabalho contemporâneo
Authors: Felipe Ednilson Silva , Vargas Juliano
Published: May 2018

O artigo examina pontos de convergência e de divergência entre a evolução do mercado nacional de trabalho contemporâneo e alguns aspectos socioeconômicos e institucionais pós 1990, via abordagem das capacitações e ideia de justiça de Amartya Sen. Dois períodos são relevantes para essa discussão: a) 1990-2002, em que o Brasil passou por processos que promoveram desregulamentação do mundo do trabalho e reconfiguração do mercado nacional de trabalho; b) 2003-2014, com participação mais efetiva do Estado e da sociedade civil dentro da perspectiva de um mundo do trabalho desregulamentado e de um mercado nacional de trabalho reconfigurado. Resulta dessa análise a observância de que a presença da sociedade e de suas instituições são indispensáveis para uma trajetória de desenvolvimento socioeconômico sustentável, via concretização de políticas públicas que aumentem a liberdade e a igualdade de oportunidades, protejam o tecido social e garantam os direitos individuais e coletivos do trabalho. A teoria seniana é ferramenta conveniente para a interpretação das mudanças do mercado nacional de trabalho, por evidenciar que o País tem longo caminho a percorrer no que se refere à promoção da equidade na justiça que favoreça a habilitação qualificada no sistema produtivo.
