This article investigates the contribution made by indigenous employees to the work of the Hong Kong Observatory from its inception and into the early twentieth century. As has so often been the case in Western histories of science, the significance of indigenous workers and of women in the Hong Kong Observatory has been obscured by the stories of the government officials and observatory director(s). Yet without the employees, the service could not have functioned or grown. While the glimpses of their work and lives are fleeting, often only revealed in minor archival references, this article seeks to interrogate these sources to make these workers' lives visible and to offer an examination of everyday working relationships at this place and point in time. It focuses on three areas. First, an exploration of who these workers were, and the role they played at the observatory. Second, an investigation of their contribution to the nascent science of meteorology. Third, an examination of available evidence - levels of high staff turnover, complaints, instances of foot dragging, or working to rule, as well as the tenacity to continue for years under difficult working conditions - to demonstrate the ability of workers to reject or to negotiate with colonial/patriarchal authority. In profiling their stories, this article will add to the literature examining the lives of scientific workers and their contributions to science, the everyday cultural and social contexts of colonial meteorology, and the role of ordinary men and women in producing meteorological knowledge at this time.

Z boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are often used to probe the nature of the strong force, improve Monte Carlo event generators, and search for deviations from standard model predictions. All previous measurements of Z boson production characterize the event properties using a small number of observables and present the results as differential cross sections in predetermined bins.

A comprehensive study of the angular distributions in the bottom-baryon decays Λ_{b}^{0}→Λ_{c}^{+}h^{-}(h=π,K), followed by Λ_{c}^{+}→Λh^{+} with Λ→pπ^{-} or Λ_{c}^{+}→pK_{S}^{0} decays, is performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of 9 fb^{-1} collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV. The decay parameters and the associated charge-parity (CP) asymmetries are measured, with no significant CP violation observed. For the first time, the Λ_{b}^{0}→Λ_{c}^{+}h^{-} decay parameters are measured.

Background: Climate change poses a significant risk to kidney health, and countries with lower national wealth are more vulnerable. Yet, citizens from lower-income countries demonstrate less concern for climate change than those from higher-income countries. Education is a key covariate.

This case report presents a newborn with pyruvate dehydrogenase complex deficiency who developed significant lactic acidosis and acute kidney injury after birth. Peritoneal dialysis with glucose-based peritoneal dialysis fluid was initially started, but the patient had worsening hyperglycemia and lactic acidosis, likely related to excess glucose reabsorption with shunting to lactate due to the underlying metabolic disorder. As amino acid-based dialysis solution was not available in our formulary, a dialysis fluid was manually created with Vaminolact, which was commonly used in neonatal parenteral nutrition.

Canine leishmaniosis (CanL), caused by Leishmania infantum, is a widespread vector-borne disease. In Italy, an endemic region for CanL, overlapping transmission of L. infantum and tick-borne pathogens (TBPs) like Anaplasma phagocytophilum and Ehrlichia canis is increasingly reported.
