The effects of superheating and cooling rate on olivine growth in chondritic liquid

Chondrules, the major constituent of chondrites, are millimeter‐sized igneous objects resulting from the crystallization of silicate liquids produced by the partial or complete melting of chondritic precursors, whose exact nature remains disputed. Various chondrule textures are observed as a function of the extent of the initial melting event. Here, we report dynamic crystallization experiments performed with a broad range of cooling rates (2–750 °C h−1) from superliquidus or subliquidus initial conditions to demonstrate the control of nucleation on the final chondrule texture. Classical crypto‐porphyritic, micro‐porphyritic, and porphyritic olivine textures were reproduced in subliquidus experiments in which heterogeneous nucleation dominates. In contrast, we were unable to reproduce barred olivine textures, regardless of the cooling rates investigated from superliquidus conditions; instead, macro‐porphyritic textures were systematically obtained at low cooling rates (<10 °C h−1). The small number and large size of crystals in the macro‐porphyritic texture are consistent with the initial step of superheating and the presence of long embayments that indicate an initial episode of rapid growth due to delayed nucleation. Crystals then acquired polyhedral shapes during a subsequent episode of slow growth. When the growth rate is too slow to decrease the degree of supersaturation in the liquid, a new episode of rapid growth produces a new generation of melt inclusions.
Correlations of CT Scan Findings in Different Types of Cerebral Palsy: A Study in a Tertiary Care Centre in Bangladesh

Introduction: Cerebral palsy (CP) is one of the most common causes of chronic childhood disability. CT scan is helpful for identification of structural abnormalities, etiology, categorize the types of brain lesions and planning of intervention in the child with CP. Objective: This study was done to find relationship between types of CP and CT scan findings of brain. Materials and methods: This cross sectional descriptive study was done among 110 clinically diagnosed CP case from department of Paediatric Neurology & IPNA, BSMMU, during March 2016 to August 2017. Demographic, clinical characteristics & physical examination were done & collected data were recorded. CT scan of brain was done in all cases & all data were analyzed. Results: The mean age of the studied children was 2.6±2.2 years (1 to 14 years). Among them quadriplegic CP were the most common (39.1%), followed by 28.2% cases of hemiplegic CP, 16.4% were of mixed type, 7.3% were diplegic. Most common finding on CT scan of brain was cerebral atrophy (62.7%), followed by encephalomalacia (15.5%), calcification (13.6%), and brain malformations (11.8%). Abnormal CT scan findings were found in 88.2% of studied children. Children with hemiplegic CP had brain atrophy in 87% of cases, calcification was found mostly in quadriplegic CP. Brain malformation was found mostly in mixed type of CP. Conclusion: Most common CT scan finding was brain atrophy and commonly found in hemiplegic CP. Encephalomalacia and calcifications were commonly found in quadriplegic CP. Brain malformation were commonly found in mixed type of CP. BANGLADESH J CHILD HEALTH 2021; VOL 45 (2) : 67-73
Quantitative Analysis of Barriers to Clubfoot Treatment Experienced at a Tertiary Care Institute in India

Introduction: The Ponseti method of treating clubfeet is considered the gold standard. However, there are specific barriers to implementing the Ponseti method for clubfoot treatment, especially in developing countries like India. Methods: This is a retrospective study on patients who underwent the Ponseti method for clubfoot treatment at a tertiary care hospital in India. A total of 110 patients were enrolled for this study and were interviewed at the initiation of treatment and at each follow-up to identify the barriers, and their correlation to dropout rate was analyzed. Results: On applying binary logistic regression, which shows the cumulative effect of all variables, the effect of the parent accompanying the patient was significant on compliance and dropout rate. Conclusion: Informed parents play a significant role in compliance with the treatment. The study results can help formulate an action plan to improve adherence to the Ponseti method for treating clubfoot throughout India and other developing countries.
Automated Movement Analysis to Predict Cerebral Palsy in Very Preterm Infants: An Ambispective Cohort Study

The General Movements Assessment requires extensive training. As an alternative, a novel automated movement analysis was developed and validated in preterm infants. Infants < 31 weeks’ gestational age or birthweight ≤ 1500 g evaluated at 3–5 months using the general movements assessment were included in this ambispective cohort study. The C-statistic, sensitivity, specificity, positive predictive value, and negative predictive value were calculated for a predictive model. A total of 252 participants were included. The median gestational age and birthweight were 274/7 weeks (range 256/7–292/7 weeks) and 960 g (range 769–1215 g), respectively. There were 29 cases of cerebral palsy (11.5%) at 18–24 months, the majority of which (n = 22) were from the retrospective cohort. Mean velocity in the vertical direction, median, standard deviation, and minimum quantity of motion constituted the multivariable model used to predict cerebral palsy. Sensitivity, specificity, positive, and negative predictive values were 55%, 80%, 26%, and 93%, respectively. C-statistic indicated good fit (C = 0.74). A cluster of four variables describing quantity of motion and variability of motion was able to predict cerebral palsy with high specificity and negative predictive value. This technology may be useful for screening purposes in very preterm infants; although, the technology likely requires further validation in preterm and high-risk term populations.

The dynamics of returns predictability in cryptocurrency markets

In this paper, we take a forecasting perspective and compare the information content of a set of market risk factors, cryptocurrency-specific predictors, and sentiment variables for the returns of cryptocurrencies vs traditional asset classes. To this aim, we rely on a flexible dynamic econometric model that not only features time-varying coefficients, but also allows for the entire forecasting model to change over time to capture the time variation in the exposures of major digital currencies to the predictive variables. Besides, we investigate whether the inclusion of cryptocurrencies in an already diversified portfolio leads to additional economic gains. The main empirical results suggest that cryptocurrencies are not systematically predicted by stock market factors, precious metal commodities or supply factors. On the contrary, they display a time-varying but significant exposure to investors' attention. In addition, also because of a lack of predictability compared to traditional asset classes, cryptocurrencies lead to realized expected utility gains for a power utility investor.
Dark Emu: Black Seeds: Agriculture or Accident?

Dark Emu argues for a reconsideration of the 'hunter-gatherer' tag for pre-colonial Aboriginal Australians and attempts to rebut the colonial myths that have worked to justify dispossession.

An Empirical Evidence of Energy Consumption and Economic Development Dynamics in Nigeria: What is the Role of Population?

The place of population growth in the linkage between the consumption of energy and economic development in Nigeria was examined in this study. Annual data on total consumption of energy, the growth of population, and economic development were employed among other variables for the time 1995 to 2019. We used Autoregressive Distributed Lag -Error Correction Model (ARDL-ECM). Energy consumption had a feedback negative substantial relationship with economic development in the long run while in the short run, energy consumption had a negative significant impact on economic development. The population growth had a negative significant impact on economic development, and a positive substantial effect on energy consumption. However, energy consumption is not impacted on by oil price. Consequently, we advocate for the increase in the quality of energy, increasing government expenditure in the provision of energy supply, and the population maximization of energy for the achievement of economic development in Nigeria.
Act or Wait-and-See? Adversity, Agility, and Entrepreneur Wellbeing across Countries during the COVID-19 Pandemic

How can entrepreneurs protect their wellbeing during a crisis? Does engaging agility (namely, opportunity agility and planning agility) in response to adversity help entrepreneurs safeguard their wellbeing? Activated by adversity, agility may function as a specific resilience mechanism enabling positive adaption to crisis. We studied 3162 entrepreneurs from 20 countries during the COVID-19 pandemic and found that more severe national lockdowns enhanced firm-level adversity for entrepreneurs and diminished their wellbeing. Moreover, entrepreneurs who combined opportunity agility with planning agility experienced higher wellbeing but planning agility alone lowered wellbeing. Entrepreneur agility offers a new agentic perspective to research on entrepreneur wellbeing.
Plant Protection in organic production of Brassica vegetables and oilseed rape

Growers of organic Brassica vegetables and oilseed rape face the same potentially severe plant protection problems as their colleagues in conventional or integrated pest management systems.Management strategies in organic systems rely on preventive measures (crop rotation, crop isolation,soil management, host plant resistance, farm/field location; manipulate timing of planting or harvest; intercropping, mulching), use of functional agro-biodiversity (reduction of pest by enhancing natural enemies), release of biocontrol agents and a few approved pesticides of biological and mineral origin, as well as mating disruption or the use of anti-insect nets (Zehnder et al., 2007). The methods used in organic might also be applicable in IPM systems. However, several factors hamper wide implementation of these methods in IPM. Among the main reasons are (1) a lower efficacy compared to standard pesticide treatments, (2) higher costs, (3) lack of knowledge / information / advice on alternative methods, (4) inconvenience, and (5) the need for close collaboration between neighbouring famers to achieve good control. In the following paper, we describe the methods used in organic Brassica vegetable and oilseed rape production, and discuss their limitations.
Interaction between Tolpyralate and Atrazine for the Control of Annual Weed Species in Corn

Abstract Many studies have documented the interaction between 4-hydroxyphenylpyruvate dioxygenase (HPPD)-inhibiting and photosystem II (PSII)-inhibiting herbicides. Most have focused on the interaction between mesotrione and atrazine, with only a few studies characterizing the nature of the interaction between tolpyralate and atrazine. Therefore, five field experiments were conducted in Ontario, Canada, over a 3-yr period (2019 to 2021) to characterize the interaction between three rates of tolpyralate (15, 30, and 45 g ai ha–1) and three rates of atrazine (140, 280, and 560 g ai ha–1) for the control of seven annual weed species in corn (Zea mays L.). Tolpyralate at 30 or 45 g ha–1 applied with atrazine at 280 or 560 g ha–1 controlled velvetleaf (Abutilon theophrasti Medik.), redroot pigweed (Amaranthus retroflexus L.), common ragweed (Ambrosia artemisiifolia L.), common lambsquarters (Chenopodium album L.), and wild mustard (Sinapis arvensis L.) >90% at 8 wk after application (WAA). Tolpyralate and atrazine were synergistic at each rate combination for the control of A. theophrasti at 8 WAA. In contrast, A. retroflexus and S. arvensis control at 8 WAA was additive with each rate combination. At 8 WAA, C. album control was generally additive, but one rate combination was synergistic. Ambrosia artemisiifolia control at 8 WAA was synergistic with five rate combinations and additive with the other four. Barnyardgrass [Echinochloa crus-galli (L.) P. Beauv. ] control at 8 WAA was additive with seven of the rate combinations and synergistic with two. Setaria spp. control at 8 WAA was synergistic with one more rate combination compared with E. crus-galli, but the two weed species shared the same synergistic rate combinations. This study concludes that extrapolation or broad classifications of the interaction between tolpyralate and atrazine would be inappropriate, as the interaction can vary due to herbicide rate, weed species, and the response parameter analyzed.
The order flow cost of index rolling in commodity futures markets

Commodity index rolling is treated as a natural experiment and an event study of order flow costs in a wide array of futures markets is conducted. The spread between nearby and deferred futures prices decreases significantly in the early and growth phases of financialization (1991-2011), with the spreads reversing back after rolling is completed. Spread impacts disappear in the post-financialization period (2012-2019). We argue that a dramatic increase in the supply of liquidity brought on by a sunshine trading effect and the transition to electronic trading in commodity futures markets is the most likely explanation for the decline of roll order flow costs.
Environmental Controls on Tornadoes and Tornado Outbreaks

ABSTRACT In this article, the global climatology of tornadoes and current understanding of the synoptic- and meso-scale environments of tornadoes and tornado outbreaks are reviewed. The study of tornadoes involves the investigation of atmospheric processes at global- to micro-scales and has advanced the understanding of multiscale processes. Global-scale circulation controls synoptic-scale processes such as extratropical cyclones, upper-level jets, and anticyclonic circulation; synoptic-scale processes affect mesoscale processes that cause severe thunderstorms and tornadoes. Studies of the near-storm environment of tornadoes and tornado outbreaks over decades have improved our understanding of differences in environmental parameters such as vertical shear and buoyancy between tornadic and nontornadic thunderstorms. Composite parameters associated with vertical shear and buoyancy have been developed and found to be skilful at predicting the potential of tornado occurrence. However, false alarm ratios for tornado prediction are still large. Since it is still a challenge to predict based on the environment whether or not a tornado will occur, further understanding of the near-storm environment of tornadoes and the development of new meteorological parameters to improve prediction skill are required in the future studies.
Assessing ecological conditions for landscape management: a comparative analysis of field measurements and perceptions

Abstract Assessments of ecosystem condition are fundamental to landscape management, and there are several sources of evidence practitioners may use. Perceptions of individuals is one of those sources, and understudied. This study quantitatively compares ecological field measurements and the perceptions of a group of key individuals. Findings reveal that perceptions did not statistically differ from the ecological assessment for elements of ecosystem composition (e.g. vegetation diversity and invasive species). However, differences were found for all other elements (e.g. ecosystem function, structure, and overall condition), such that the individuals tended to have lower ratings of ecosystem condition than ecological assessments. The findings highlight the importance of comparing different approaches for reciprocal verification of data and to identify opportunities to integrate evidence, thereby providing a more detailed picture of ecosystem condition.
Enhanced Improvement Of Vehicle Dynamic Behaviour By Applying Torque Vectoring

To ensure that the Tyre Estimator®, a program developed by TNO to generate axle characteristics, can cope with TV, additions have to be made. The motor torque need to be measured so the extra yawmoment due to TV can be calculated. Additionally the vehicle models inside the Tyre Estimator® need to be modified to apply this extra yaw-moment on the z-axis (perpendicular to the road) of the vehicle model. Example of the used energy with and without Torque Vectoring. Graduates: HAN University S. Nada S.J. Koster
Local recurrence risk in head and neck basal cell carcinoma.

PURPOSE The aim of the study was to ascertain the risk factors of local recurrence in primary basal cell carcinoma of the head and neck Material and methods: A retrospective analysis of 545 patients with head and neck primary basal cell carcinoma treated in years 2008 - 2018 was done. The following data was recorded: age, sex, tumor site, histological subtype, greatest dimension, margin status, experience of operating surgeon and local recurrence Results: Most of the tumors were located nose (165; 30,2%) and auricle (119; 21,8%). The most common pathological subtype was nodular (119; 21,8%). Three hundred and ninety-four tumors (72,2%) were under 20mm in diameter. Positive surgical margins were noted in 107 (19,6%) cases. Local recurrence was observed in 52 (9,5%) cases, of which 29 (29/107; 27%) had positive surgical margins, in 23 (23/438; 5,2%) cases margins were free, which was the only statistically significant factor (p<0,001; OR 6,71; CI 3,69 - 12,2). CONCLUSIONS The results of our study have shown that positive surgical margin remains the strongest risk factor for local recurrence. With surgical excision being the gold standard of treatment the greatest emphasis should be placed on avoiding such scenario in high risk patients.
Analysis on Acupoint Selection and Combination for Amyotrophic Lateral Sclerosis Treated with Acupuncture Based on Data Mining

Objective The aim of the study was to explore the regularity of acupoints in the treatment of amyotrophic lateral sclerosis (ALS) by means of data mining technology. Methods Nine databases, including SinoMed, Chongqing VIP (CQVIP), China National Knowledge Infrastructure (CNKI), Wanfang Data, Cochrane Library, PubMed, MEDLINE, Web of Science, and Embase, were comprehensively searched till December 2021. The published clinical literature testing acupuncture in the treatment of ALS was eligible for inclusion. Studies were organized to establish the prescription database. Modular data mining analysis, including acupoint frequency, complex network analysis, association rule analysis, and cluster analysis were used to conduct statistical analysis. Results Forty-two literature studies on 141 acupoints were included, involving 626 times the total application frequency. The top 5 acupoints in application frequency were Hegu (LI 4, 67%), Zusanli (ST 36, 67%), Quchi (LI 11, 52%), Sanyinjiao (SP 6, 48%), and Yanglingquan (GB 34, 45%). The most involved meridian was the large intestine meridian of hand Yangming (90 times). The generally used acupoints were mainly distributed in the lower limbs. The top 5 combinations in application frequency were Hegu-Quchi (75 times), Quchi-Zusanli (66 times), Zusanli-Sanyinjiao (54 times), Hegu-Sanyinjiao (54 times), and Quchi-Sanyinjiao (49 times). The acupoint combinations with the strongest association were Quchi, Hegu, Zusanli, Sanyinjiao, and Shousanli (LI 10). There were 7 acupoint groups according to the cluster analysis. The core prescriptions were Hegu, Zusanli, Quchi, and Jiaji (EX-B 2). Conclusions Hegu, Zusanli, Quchi, and Jiaji could be used as the main prescriptions in treating ALS. The combination of Quchi, Hegu, Zusanli, and Sanyinjiao should be selected with priority in acupuncture therapy.
