TL;DR: This companion volume explains in depth the meaning, or semantic theory, of ML.
Abstract: The full mathematical description of the functional programming language ML was given in Milner, Tofte, and Harper's Definition of Standard ML. This companion volume explains in depth the meaning, or semantic theory, of ML.

TL;DR: The aqueous leaf extract of Vernonia amygdalina, Del, (Compositae) produced a dose‐related fall in blood sugar and may involve a mechanism not related to insulin secretion.
Abstract: The aqueous leaf extract of Vernonia amygdalina, Del, (Compositae) given i.p. produced a dose-related fall in blood sugar. A dose of 80 mg/kg body weight of adult rabbit produced a maximum lowering of blood sugar in both fasted normal and alloxanized rabbits. The fasting blood sugar in normoglycaemic rabbits was reduced from 96 mg% to 48 mg% in 4 h. In alloxanized rabbits, the blood sugar was reduced from the mean value of 520 mg% to 300 mg% in 8 h. The hypoglycaemic effects were compared with those of tolbutamide. Acute toxicity studies of the extract in mice gave LD50 value of 1122 mg/kg body weight when given i.p. The blood sugar lowering effect of Vernonia amygdalina extract may involve a mechanism not related to insulin secretion.

TL;DR: In this paper, the additive and techniques applied for stabilizing expansive soils will be focused on, with respect to their efficiency in improving the engineering properties of the soils, and some issues regarding the effective application of the emerging trends in expansive soil stabilisation were presented with three categories, namely geoenvironmental, standardisation and optimisation issues.
Abstract: Expansive soils are problematic due to the performances of their clay mineral constituent, which makes them exhibit the shrink-swell characteristics. The shrink-swell behaviours make expansive soils inappropriate for direct engineering application in their natural form. In an attempt to make them more feasible for construction purposes, numerous materials and techniques have been used to stabilise the soil. In this study, the additives and techniques applied for stabilising expansive soils will be focused on, with respect to their efficiency in improving the engineering properties of the soils. Then we discussed the microstructural interaction, chemical process, economic implication, nanotechnology application, as well as waste reuse and sustainability. Some issues regarding the effective application of the emerging trends in expansive soil stabilisation were presented with three categories, namely geoenvironmental, standardisation and optimisation issues. Techniques like predictive modelling and exploring methods such as reliability-based design optimisation, response surface methodology, dimensional analysis, and artificial intelligence technology were also proposed in order to ensure that expansive soil stabilisation is efficient.

TL;DR: In this paper, the hydrogeochemical characteristics, water quality and health risk statuses of waters in Umunya district, southeastern Nigeria were studied, in attempt to evaluate their suitability for drinking and domestic purposes.
Abstract: The hydrogeochemical characteristics, water quality and health risk statuses of waters in Umunya district, southeastern Nigeria were studied, in attempt to evaluate their suitability for drinking and domestic purposes. Twelve groundwater and 3 surface water samples were analyzed for 26 physicochemical and hydrogeochemical parameters, using standard techniques. Results show that dominance of cations and anions is in the order Ca2+ > Na+ > K+ > Mg2+ and HCO3– > Cl– > NO3– > SO4–, respectively. Order of dominance of the heavy metals is Pb > Zn > Fe > Ni > Mn > Cr > Ba. Eight water types were identified, with Ca–Na–HCO3 (26.66%) and Na–Cl–HCO3 (20%) dominating the study area. All the water types characterize five major facies. Further, the result revealed that the physical properties and chemical ionic concentrations in the waters are well below standard maximum permissible limits, although majority of the samples have pH values off the allowable limits of 6.5–8.5, classing the waters as slightly acidic. Generally, the water quality in the study area is deteriorated due to the presence of high levels of heavy metals. Water quality index results show that 46.67% of the water samples are in excellent and good categories. 13.33% are in poor water category, whereas 40% are in category unsuitable for drinking purposes. A good percentage of the waters predispose users to health risks. Stoichiometric and statistical analyses revealed that the variations in chemistry and quality of the waters are due to combined influence of human activities and geogenic processes (silicate weathering and ionic exchanges). Treatment of contaminated waters before use is, therefore, recommended.

TL;DR: To achieve universal coverage using health financing as the strategy, there is a dire need to review the system of financing health and ensure that resources are used more efficiently while at the same time removing financial barriers to access by shifting focus from OOPs to other hidden resources.
Abstract: The way a country finances its health care system is a critical determinant for reaching universal health coverage (UHC). This is so because it determines whether the health services that are available are affordable to those that need them. In Nigeria, the health sector is financed through different sources and mechanisms. The difference in the proportionate contribution from these stated sources determine the extent to which such health sector will go in achieving successful health care financing system. Unfortunately, in Nigeria, achieving the correct blend of these sources remains a challenge. This review draws on relevant literature to provide an overview and the state of health care financing in Nigeria, including policies in place to enhance healthcare financing. We searched PubMed, Medline, The Cochrane Library, Popline, Science Direct and WHO Library Database with search terms that included, but were not restricted to health care financing Nigeria, public health financing, financing health and financing policies. Further publications were identified from references cited in relevant articles and reports. We reviewed only papers published in English. No date restrictions were placed on searches. It notes that health care in Nigeria is financed through different sources including but not limited to tax revenue, out-of-pocket payments (OOPs), donor funding, and health insurance (social and community). In the face of achieving UHC, achieving successful health care financing system continues to be a challenge in Nigeria and concludes that to achieve universal coverage using health financing as the strategy, there is a dire need to review the system of financing health and ensure that resources are used more efficiently while at the same time removing financial barriers to access by shifting focus from OOPs to other hidden resources. There is also need to give presidential assent to the national health bill and its prompt implementation when signed into law.
