Broad cultural similarities are apparent between Neolithic sites across the Middle Nile Valley, yet local variation may also be witnessed. The dearth of well-preserved skeletal assemblages in this region means that biological connections between populations, and thus potential modes for the transmission of material culture, are not well understood. Here, the authors compare dental morphological traits in five Neolithic cemeteries (c. 5600–3800 BC) and 14 time-successive sites to explore biological relatedness along the Middle Nile Valley. Their findings parallel the artefactual evidence, suggesting that the spread of the Nubian Neolithic may have been as nuanced as the populations who practised it.

What is a populist judge, and when do judges embrace populism? Populist judges bypass legal and procedural constraints, seek an unmediated relationship with the public, and claim to represent the public better than political elites. Judicial populism can emerge in response to institutionalized dissonance in the political system. Dissonant institutionalization facilitates contestation between state institutions and can undermine the legitimacy of political institutions. This legitimacy crisis can imbue judges with a belief in their role as representatives of the public interest. In Pakistan, the dissonance caused by unresolved differences between the civil-military bureaucracy and the elected political leadership—differences that were embedded into the constitutional framework, facilitated the rise of judicial populism. I outline the key features of judicial populism and study the dynamics surrounding the rapid expansion of populist jurisprudence between 2005 and 2019 in Pakistan, with a focus on public interest litigation that became the cornerstone of the judiciary’s populist turn. Through case analysis, archival research, and semi-structured interviews, I discuss features of the populist approach to jurisprudence and trace how dissonance within Pakistan’s political system created new opportunities for the judiciary and changed judicial role conceptions within the legal and judicial community.

KSB stability holds at codimension $1$ points trivially, and it is quite well understood at codimension $2$ points because we have a complete classification of $2$-dimensional slc singularities. We show that it is automatic in codimension $3$.

Propolis, as a by-product of honey production, has shown several beneficial effects on cardiovascular risks in past randomised controlled trials, although the findings are not conclusive. In this review, we intend to evaluate the effects of propolis consumption on cardiovascular risk factors by conducting a meta-analysis. The Web of Science, Medline and Scopus databases were comprehensively searched until September 2023. Eligible studies were identified by screening, and their data were extracted. Weighted mean differences with a 95 % CI for each outcome were estimated using the random-effects model. This meta-analysis revealed that propolis consumption led to a significant decrease in the levels of TAG (weighted mean differences (WMD): –10·44 mg/dl 95 % CI: –16·58, –4·31; P = 0·001), LDL-cholesterol (WMD: –9·31 mg/dl; 95 % CI: –13·50, –5·12 mg; P < 0·001), fasting blood glucose (WMD: –7·30 mg/dl; 95 % CI: –11·58, –3·02; P = 0·001), HbA1c (WMD: –0·32 %; 95 % CI: –0·60, –0·05; P = 0·01), insulin (WMD: –1·36 μU/ml; 95 % CI: –2·36, –0·36; P = 0·007), homeostatic model assessment for insulin resistance (WMD: –0·39; 95 % CI: –0·74, –0·03; P = 0·020) and systolic blood pressure (WMD: –2·24 mmHg 95 % CI: –4·08, –0·39; P = 0·010), compared with the control groups. Furthermore, propolis consumption had a significant increasing effect on HDL-cholesterol levels (WMD: 2·03 mg/dl; 95 % CI: 0·24, 3·83; P = 0·020). In contrast, the consumption of propolis had no significant effect on total cholesterol and diastolic blood pressure levels. This systematic review and dose–response meta-analysis suggested that propolis intake may be effective in cardiometabolic improvement in adults. Further, well-designed studies are required to confirm and elucidate all aspects of these findings.

To investigate the flame acceleration to detonation in 2.0 and 0.5 mm planar glass combustion chambers, the experiments have been conducted utilising ethylene/oxygen mixtures at atmospheric pressure and temperature. The high-speed camera has been used to record the revolution of flame front and pressure inside the combustion chamber. Different equivalence ratios and ignition locations have been considered in the experiments. The results show that the detonation pressure in the 2 mm thick chamber is nearly three times of Chapman-Jouguet pressure, while detonation pressure in the 0.5 mm thick chamber is only 45.7% of the Chapman-Jouguet value at the stoichiometric mixture. This phenomenon is attributed to the larger pressure loss in the thinner chamber during the detonation propagation. As the value of equivalence ratio is 2.2, the detonation cannot be produced in the 2 mm thick chamber, while the detonation can be generated successfully in the 0.5 mm thick chamber. This phenomenon indicates that the deflagration is easily to be accelerated and transformed into the detonation, due to a larger wall friction and reflection. Besides, the micro-obstacle has been added into the combustor can shorten the detonation transition time and reduces the distance of the detonation transition.
