Prognosis and Survival of Medullary Carcinoma of the Breast

48 Medullary breast carcinoma (MBC) is a rare tumor, representing 3% to 5% of invasive breast carcinomas [1,2]. The World Health Organization defines it as a well-circumscribed invasive tumor, composed of poorly differentiated cells, arranged in sheets, without gland formation and a scarce collagen stroma with the presence of a very prominent lymphoplasmacytic infiltrate [3]. In 1977 Ridolfi et al. [4] proposed five specific histopathological criteria for diagnosis: well-circumscribed tumor, syncytial architecture in al less than 75% of the areas examined, diffuse stromal infiltration with lymphocytes and plasma cells, absence of tubular differentiation and/or intraductal component, that is, forms of glandular patterns, and moderate or marked anisonucleosis.

A Review on home oxygen therapy (HOT) in severe chronic obstructive pulmonary disease (COPD) patients with resting Hypoxemia

Home oxygen therapy often abbreviated as HOT refers to the basic treatment used among patients with acute chronic obstructive pulmonary disease (COPD). The treatment is suitable for use among patients with resting hypoxemia. The objective of this research was to assess the risks, adherence, benefits, as well as the perception of HOT. The primary risk identified in this research relates to burns developing among patients on HOT. In all the studies included in this review, the most popular reason for burns was smoking while on HOT. It is clear from this study that HOT increased the rate of survival among COPD patients diagnosed with mild to moderate and acute hypoxemia. This research recommends the need for more investigation to be carried out to identify additional benefits of participating in HOT. It was evident that patients who were trained on HOT clearly understood the benefits of oxygen and had a superior rate of adherence to this form of treatment compared to those who did not receive any form of training. The outcome of most studies showed positive experiences among patients on HOT. However, the experiences of the patients differed and a few of them reported having negative perceptions. In general, additional scholarly work is needed to examine the thoughts of the patients on HOT and the factors allied to those perceptions. This study can be useful in improving the clinical practice of HOT.
Automatic Hate Speech Detection using Machine Learning: A Comparative Study

The increasing use of social media and information sharing has given major benefits to humanity. However, this has also given rise to a variety of challenges including the spreading and sharing of hate speech messages. Thus, to solve this emerging issue in social media sites, recent studies employed a variety of feature engineering techniques and machine learning algorithms to automatically detect the hate speech messages on different datasets. However, to the best of our knowledge, there is no study to compare the variety of feature engineering techniques and machine learning algorithms to evaluate which feature engineering technique and machine learning algorithm outperform on a standard publicly available dataset. Hence, the aim of this paper is to compare the performance of three feature engineering techniques and eight machine learning algorithms to evaluate their performance on a publicly available dataset having three distinct classes. The experimental results showed that the bigram features when used with the support vector machine algorithm best performed with 79% off overall accuracy. Our study holds practical implication and can be used as a baseline study in the area of detecting automatic hate speech messages. Moreover, the output of different comparisons will be used as state-of-art techniques to compare future researches for existing automated text classification techniques.
Transformation and Utilization of Agricultural Waste as Component of Green Concrete for Rural Housing and Development Schemes

Several researchers have outlined cost saving and cement blending merits without compromising standards. As such, utilizing artificial pozzolana as supplementary cementitious materials (SCMs) in concrete engineering is well known. However, there is continual search for substitute materials. The use of Rice Husk Ash (RHA) as cementitious constituent in green concrete was studied. Its abundance paved way for the study to look into the compressive strength of the concrete type formed by partly substituting Ordinary Portland Cement (OPC) with RHA under short curing series. Analysis on RHA revealed significant properties of pozzolanic hardening. 60 cubes of 100 mm dimensions were cast with cement replacement by RHA ranging from 0-40% while adopting a 28 day targeted strength of 25 MPa as control. The cubes were cured at relative humidity (RH) of 95-100% and temperature (T) of 22-25 0 C in a chamber for periods of 7, 14, 21 and 28 days. The outcomes displayed trends of strength gain, reduced density and compressive strength with increase in RHA. The 28 days density and strength of the normal concrete was 2465 kg/m 3 and 28.57 MPa while the 10% RHA sample (i.e. best substitute matrix) had 2398 kg/m 3 and 25.97 MPa respectively. The strength of 10% RHA/OPC concrete (25.97 MPa) was slightly higher than the adopted strength (25 MPa) at 28 days. This signifies its suitability as concrete constituents and can be a major cost reduction factor in rural shelter projects where less structural complexities are required. Hence, it can be employed in the construction of simple foundations and concrete composites.
Using cpDNA to Assess Species Delimitation between Liatris helleri Porter (Asteraceae) and Liatris turgida Gaiser

Liatris helleri is a federally-threatened perennial species endemic to nine populations in Western North Carolina. Evidence suggests that L. helleri is morphologically indistinguishable from L. turgida, and thus should be subsumed into a single species. However, conservation agencies often test several species concepts before altering species delimitations. This has been the case with L. helleri, as ecological differences between L. helleri and L. turgida have raised questions about the validity of classifying L. helleri using morphology alone. We amplified regions of chloroplast DNA in order to test the Phylogenetic Species Concept. We hypothesized that L. helleri and L. turgida are distinct species, and thus should form two distinct monophyletic groups. Phylogenetic analyses recovered two clades, neither of which was monophyletic for L. helleri or L. turgida. TCS analysis revealed a central set of L. helleri populations which gave rise to three independent radiations of L. turgida. Our results do not support recognition of L. helleri and L. turgida as distinct species, and suggest that L. helleri and L. turgida are in some phase of a speciation event. We recommend continued protection of L. helleri pending further evidence of speciation, and that conservation efforts focus on this central cluster of populations.
Air–water gas exchange in lakes and reservoirs measured from a moving platform by underwater eddy covariance

Air–water exchange rates of gasses, such as O2, CO2, and CH4, are widely used in ecosystem studies of lakes and reservoirs, but their magnitudes are often difficult to assess. In this proof‐of‐concept study, we measured gas exchange by underwater eddy covariance in such lentic systems from a moving platform. We used an Acoustic Doppler Velocimeter and a fast‐responding O2‐temperature sensor mounted in the bow of a boat to measure water velocity, O2 concentration, and temperature below the air–water interface (~ 10 cm) while the boat was propelled at constant speed (~ 25 cm s−1) by an electric trolling motor. Fluxes of O2 and heat across the air–water interface and standard gas exchange coefficients, k600, were calculated for every 3 min of traveled distance (~ 45 m). All deployments were done under calm low‐wind conditions where empirical relationships for k600 are most uncertain. Deployment averages of k600 ranged from 0.070 to 0.39 m d−1 and were strongly correlated with both the heat flux and the water temperature. In one deployment, a > 20% variation in mean water column O2 concentration was measured along a 1 km long transect of a reservoir. Given the typical size of O2 concentration differences over the air–water interface that drive gas exchange, such lateral variations can, even at a near‐constant exchange coefficient, result in highly biased whole‐ecosystem fluxes if based on stationary single‐point O2 measurements. “Mobile” aquatic eddy covariance measurements enable quantification of gas exchange in lakes and reservoirs under true in situ conditions and with high temporal and spatial resolution.
A Multitier Open-Ended Momentum And Impulse (MOMI) Instrument: Developing And Assessing Quality Of Conception Of 11

Physics education scholars have revealed that students have some difficulties and misconceptions in basic physics concepts in mechanics including momentum and impulse. The purpose of this study was to develop a valid and dependable Multitier open-ended momentum and impulse (MOMI) diagnostic test to evaluate students’ understanding. For developing this test, 14 multiple-choice with open-ended questions were administered to high school students with 28 participant of 11-grade students (13 male students called “ujang” and 15 female students called “eneng”). The MOMI instrument contain of 14 question which analyzed by Rasch. Students' conceptions have already been considered regarding to six categories; Sound Understanding (SU), Partial Positive (PP), Partial Negative (PN), Misconception (MC), No Understanding (NU), and No Coding (NC). Category student’s conception with the highest percentage is 36% (SU) and the highest student’s misconception is 54% (MC) as the result of this research.
1 2 Awe or horror : Differentiating two emotional responses to schema-incongruence 3 4

1 Experiences that contradict one’s core concepts (e.g. of the world, people, the self) 2 elicit intense emotions. Such schema incongruence can elicit awe, wherein experiences that 3 are too vast to understand with existing cognitive schemata cause one to feel that schemata 4 should be updated [i.e., a “need for cognitive accommodation” (NFA); Keltner & Haidt, 5 2003]. However, other emotional responses to schema incongruence, such as horror, have not 6 been investigated. 7 The current studies compared awe and horror to investigate if they are distinct 8 schema-incongruent emotional responses. Study 1 observed significant differences between 9 awe and horror in cognitive appraisals (e.g., certainty, legitimacy), indicating several areas of 10 dissimilarity. Study 2 found evidence that awe and horror are both responses to schema11 incongruence, as schema incongruence and NFA were salient in awe and horror, but not a 12 contrast emotion. However, awe and horror were elicited by different types of schema 13 incongruence: awe by spiritual vastness, horror by extremity. Awe-eliciting experiences also 14 appeared to be easier to assimilate than horrifying experiences, as NFA and uncertainty were 15 significantly lower in awe than in horror. Differences in the functions of horror and awe are 16 also discussed. 17 Word count: 185 18

EFFECT OF GOLDEN APPLE SNAIL (Pomacea canaliculata) MEAT AS FEEDS ON THE GROWTH AND SURVIVAL RATES AND BIOCHEMICAL COMPOSITION OF MUD CRAB (Scylla serrata)

Mud crab is considered a new species in aquaculture, widespread interest in its culture is increasing due to rising market valueof mud crabs. At present shrimp feeds and trash fish are currently used as feed stuff for mud crabs, however, their prices are continually r Finding low cost feed supplies has been identified as one of the key challenges facing the rapid growth of the mud crab farming sector in Asian countries. The study aimed to compare the effect of five different feed types GAS meat, trash fish, shrimp feed, GAS meat + trash fish, GAS meat + shrimp feed, to the growth and survival rate, % biochemical compositions and economic viability of 75 pieces lean mud crabs (Scylla serrata) fattened for 20 days. Mud crabs were stocked individually in plastic cases fitted in bamboo frames and installed in brackish water pond. Results showed that mean final weight, carapace length and width of mud crabs fed with GAS meat do not differ significantly (P>0.05) among other treatments. 100% survival rates were recorded on mud crabs fed with GAS meat, TrF and GAS meat + TrF. Protein content is highest in GAS+TrF – fed mud crabs. Costbenefit analysis showed that GAS meat + TrF diet resulted to highest gain. In conclusion, golden apple snail (Pomacea canaliculata) meat is a potential feed source for the mud crab diet as an alternative to trash fish and shrimp feed.

Adding Blood to St Thomas Solution Does Not Improve Mortality in Pediatric Cardiac Surgery: A Meta-analysis of a Homogenous Population

Background: Cardioplegia is the gold standard for providing ideal operating conditions while effecting myocardial protection. Some studies suggest that adding blood to St Thomas cardioplegia solution improves efficacy; this is generally accepted as true. However, the few meta-analyses conducted on children have pooled heterogeneous populations; this raises concern about the validity of their conclusions. Methods: PUBMED, the Cochrane Library and Google Scholar were searched systematically until March 2019 using the search terms “cardioplegia”; “myocardial protection”; “pediatric” “pediatric”; “children”; “infants”; “neonates”. Full text articles were examined if abstracts revealed that the studies possibly contained a blood cardioplegia arm and a crystalloid cardioplegia arm. Studies were included in the meta-analysis if they had a 4:1 blood cardioplegia arm and a St Thomas solution arm. Meta-analysis was performed using Meta-Mar software. Results: The search retrieved 423 articles; 5 were included in the meta-analysis, representing 324 patients. The risk ratio for operative mortality was 0.77(95% CI 0.24–2.5; p=0.66). Little evidence was seen of heterogeneity of the pooled patients. Conclusion: Adding blood to St Thomas cardioplegia solution did not improve in-hospital operative mortality; this may have implications for use of blood cardioplegia.
Title Losing Confidence Over Time: Temporal Changes in Self- Esteem Among Older Children and Early Adolescents in Japan, 1999-2006

We examined temporal changes in self-esteem among elementary and middle school students in Japan. Previous research has shown that self-esteem decreased among various sectors of the population, from middle school students to adults between 1984 and 2010 in Japan. However, it was unclear whether such temporal changes are also present at earlier stages of development (e.g., in elementary school) and in individual subgroups (e.g., each gender and developmental stage). Identifying such boundary conditions of temporal change will contribute to a better understanding of how cultures change over time. We analyzed representative and large-sample time-series data collected by the Japanese government in 1999 and 2006. Results showed that self-esteem decreased among elementary and middle school students regardless of gender and developmental stage. We suggest that from an early stage of development and among a broad range of the population in Japan, people’s general self-evaluations became more negative between 1999 and 2006.
Running title : Game theory and urban gull kleptoparasitism

19 Kleptoparasitism (food stealing) is a significant behaviour for animals that forage in social 20 groups as it permits some individuals to obtain resources whilst avoiding the costs of 21 searching for their own food. Evolutionary game theory has been used to model 22 kleptoparasitism, with a series of differential equation based compartmental models 23 providing significant theoretical insights into behaviour in kleptoparasitic populations. In this 24 paper we apply this compartmental modelling approach to kleptoparasitic behaviour in a real 25 foraging population of urban gulls (Laridae). Field data was collected on kleptoparasitism 26 and a model developed that incorporated the same kleptoparasitic and defensive strategies 27 available to the study population. Two analyses were conducted: 1. An assessment of whether 28 the density of each behaviour in the population was at an equilibrium. 2. An investigation of 29 whether individual foragers were using Evolutionarily Stable Strategies (ESS) in the correct 30 environmental conditions. The results showed the density of different behaviours in the 31 population could be at an equilibrium at plausible values for handling time and fight duration. 32 Individual foragers used aggressive kleptoparasitic strategies effectively in the correct 33 environmental conditions but some individuals in those same conditions failed to defend food 34 items. This was attributed to the population being composed of three species that differed in 35 competitive ability. These competitive differences influenced the strategies that individuals 36 were able to use. Rather than gulls making poor behavioural decisions these results suggest a 37 more complex three-species model is required to describe the behaviour of this population. 38
Seasonal and Interannual Variations of Yellowfin Tuna Catches along the Omani Shelf

Yellowfin tuna contributed markedly to Omani catches of the past 30 years. However, artisanal catches vary over seasons and years, and induce economic losses. With this regard, the analysis of seasonal and interannual fluctuations of Yellowfin tuna catches was carried out, based on monthly and annual time series of 20 environmental variables. Data were subjected to the Principle Component Analysis and the Multiple Ridge Regression Analysis. It was shown that catches along the Omani shelf, in 1988-2018, were subjected to a human-induced and environmental forcing subjected to seasonal and interannual variations. Seasonal variations demonstrated a bimodal trend, with a major peak in April and a minor one in October, observed during spring and fall inter-monsoon seasons. Apart from the seasonality of fishing efforts associated with rough weather during the Southwest Monsoon, seasonal variations of catches were statistically related to 9 environmental variables (namely, the wind speed, zonal gradient of sea surface temperature, geostrophic current velocity, dissolved oxygen concentration and sardine catches (an indicator of food for tuna), the amount of mesoscale eddies, mixed layer depth, photosynthetically available radiation, and outgoing longwave radiation ), that explained 71% of observed seasonal variations of the tuna catch. Due to the four-fold increase in fishing efforts, artisanal catches of Yellowfin tuna along the Omani shelf exhibited a two-fold increase over the past three decades. However, the catch per unit of effort did not show statistically confirmed increase for this time range. Interannual variations of catches exhibited an irregular pattern, with several peaks (in 1995, 2004 and 2018, with the later one still not resembled entirely). Statistical analysis implied 8 environmental variables, which modulated these variations: the wind *Corresponding author 428 Saud Al Jufaili and Sergey A. Piontkovski speed, amount of cyclonic eddies, sardines (an indicator of food resource for tuna), concentration of nitrates, atmospheric pressure gradient, sea surface temperature, El Niño-Southern Oscillation, and Indian Ocean Dipole anomalies. Coupling of these variables explained 70% of interannual variations of Yellowfin tuna catch along the Omani shelf overlooking the western Arabian Sea. The relationship between catches, El-Niño Southern Oscillation and Indian Ocean Dipole index pointed to a certain “numeric match” of two atmospheric anomalies that should happen, to favor maximal tuna catches.
