    Abstract The eastern, largely subtropical KwaZulu-Natal province of South Africa has a varied geology, climate and topography that ranges from high mountain peaks to beaches lapped by the Indian Ocean, so presenting a vast diversity of habitats that support a rich and diverse flora. Aloes are well represented throughout KwaZulu-Natal, with four genera [Aloe L., Aloiampelos Klopper and Gideon F.Sm., Aloidendron (A.Berger) Klopper and Gideon F.Sm. and Aristaloe Boatwr. and J.C.Manning] and 49 infrageneric taxa occurring in the province. The species range from trees that can reach a height of 20 m, through large, iconic single-stemmed plants, to miniatures of only a few centimeters tall. Fourteen of the aloes of KwaZulu-Natal are endemic and eleven near-endemic to the province.This paper presents a complete floristic treatment of the aloes of KwaZulu-Natal in the form of a synoptic review. Included are an identification key to the aloes that occur naturally in the province, morphological descriptions, notes on habitat, conservation status and threats to the survival of each taxon, species-level distribution maps and images of all the taxa, so providing for the first time, an up-to-date, illustrated account of aloe occurrence in this part of the subcontinent

    Abstract Molecular chirality has traditionally been viewed as a binary property where a molecule is classified as either chiral or achiral, yet in recent decades, mathematical methods for quantifying chirality have been explored. Here, we use toy molecular systems to systematically compare the performance of two state-of-the-art chirality measures: (1) the Continuous Chirality Measure (CCM) and (2) the Chirality Characteristic (χ). We find that both methods exhibit qualitatively similar behavior when applied to simple molecular systems such as a four-site molecule or the polymer double-helix, but we show that the CCM may be more suitable for evaluating the chirality of arbitrary molecules or abstract structures such as normal vibrational modes. We discuss a range of considerations for applying these methods to molecular systems in general, and we provide links to user-friendly codes for both methods. We aim for this paper to serve as a concise resource for scientists attempting to familiarize themselves with these chirality measures or attempting to implement chirality measures in their own work.

  5. Article: Cadmium in New Zealand agricultural soils

    Abstract I summarised cadmium concentrations from soil samples collected by the fertiliser industry between 2006 and 2015, and from soil samples collected by regional councils. Using these data, a statistical model was used to estimate soil cadmium concentrations on agricultural land within each territorial authority. Across New Zealand, most territorial authorities (56 of 66), including all the South Island, had mean soil cadmium concentrations below 0.6 mg Cd/kg. The highest mean soil cadmium values on agricultural land were in the Otorohanga and Matamata-Piako districts (0.90 and 0.89 mg Cd/kg, respectively). In these districts, around 1% of properties were estimated to have mean soil cadmium in excess of 1.8 mg Cd/kg. The fertiliser industry requires that cadmium concentrations in phosphate fertiliser are below a voluntary limit of 280 mg/kg P. The mean cadmium concentration in fertiliser samples taken between 2003 and 2015 was 184 mg Cd/kg P, 66% of the voluntary limit.

    Abstract With the growing involvement of fathers in childrearing and the application of neuroscientific tools to research on parenting, there is a need to understand how a father's brain and neurohormonal systems accommodate the transition to parenthood and how such neurobiological changes impact children's mental health, sociality, and family functioning. In this paper, we present a theoretical model on the human father's brain and the neural adaptations that take place when fathers assume an involved role. The neurobiology of fatherhood shows great variability across individuals, societies, and cultures and is shaped to a great extent by bottom-up caregiving experiences and the amount of childrearing responsibilities. Mechanisms of mother-father coparental brain coordination and hormonal correlates of paternal behavior are detailed. Adaptations in the father's brain during pregnancy and across the postpartum year carry long-term implications for children's emotion regulation, stress management, and symptom formation. We propose a new conceptual model of HEALthy Father Brain that describes how a father's brain serves as a source of resilience in the context of family adversity and its capacity to "heal", protect, and foster social brain maturation and functionality in family members via paternal sensitivity, attunement, and support, which, in turn, promote child development and healthy family functioning. Father's brain provides a unique model on neural plasticity as sustained by committed acts of caregiving, thereby affording a novel perspective on the brain basis of human affiliation.

    Abstract Despite the desirability of polymers for use in many products due to their flexibility, light weight, and durability, their status as thermal insulators has precluded their use in applications where thermal conductors are required. However, recent results suggest that the thermal conductance of polymers can be enhanced and that their heat transport behaviors may be highly sensitive to nanoscale control. Here we use non-equilibrium molecular dynamics simulations to study the effect of mechanical twist on the steady-state thermal conductance across multi-stranded polyethylene wires. We find that a highly twisted double-helical polyethylene wire can display a thermal conductance up to three times that of its untwisted form, an effect which can be attributed to a structural transition in the strands of the double helix. We also find that in thicker wires composed of many parallel strands, adding just one twist can increase its thermal conductance by over 30%. However, we find that unlike stretching a polymer wire, which causes a monotonic increase in thermal conductance, the effect of twist is highly non-monotonic, and certain amounts of twist can actually decrease the thermal conductance. Finally, we apply the Continuous Chirality Measure (CCM) in an attempt to explore the correlation between heat conductance and chirality. The CCM is found to correlate with twist as expected, but we attribute the observed heat transport behaviors to structural factors other than chirality.

    Abstract Case: A three year, 11 month old girl sustained a right displaced extension supracondylar fracture (ESF) of the humerus with comminution of the lateral column after an indoor fall. At surgery, fracture reduction showed multidirectional instability. Adequate reduction was achieved by applying longitudinal traction of the arm with partial elbow flexion and forearm supination. One percutaneous medial pin, followed by one lateral cross pin, was used to immobilize the fracture. Normal posterolateral new periosteal bone formation was seen on radiograph on the lateral side. At 5-year follow-up, she had full range of asymptomatic and symmetrical elbow motion.
    Conclusion: This case report shows a displaced ESF with a comminuted lateral humeral column, which contributed to a lack of adequate lateral pin purchase on bone. A modified pin fixation technique first with a medial pin and followed by a lateral pin with both placed through the medial column was used for stable fracture fixation. In addition, this case showed that fracture comminution was a contributory factor to the rare multidirectional instability of the Gartland Type IV fracture.
