The effect of permanent protective netting on insect pest prevalence in citrus orchards in South Africa

African Entomology, 2023
The use of protective netting is becoming an increasingly popular practice in the citrus industry in South Africa. However, data on its effects on biotic factors, particularly insect pests, are limited. This study focused on the effect nets have on key citrus pests in the Eastern Cape province.

Prevalence and Distribution of Peste Des Petits Ruminants Virus Infection in Small Ruminants [PDF]

International Journal of Infectious Diseases, 2008
Abstract Peste des petits ruminants (PPR) is an acute febrile viral disease of small ruminants characterized by mucopurulent nasal and ocular discharges, necrotizing stomatitis, enteritis and pneumonia. The disease is endemic in Pakistan causing heavy economic losses due to high rate of mortality and morbidity. The present study was conducted in view

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

Advanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Prevalence, Distribution, and Host Range ofPeste des petits ruminants virus, Turkey

Emerging Infectious Diseases, 2002
Peste des petits ruminants virus (PPRV, genus Morbillivirus), which causes a severe disease in sheep and goats, has only recently been officially declared to be present in Turkey. We carried out a study to determine the prevalence, distribution, and host range of PPRV in Turkey. A total of 1,607 animals, reared in 18 different locations, were monitored

Dual‐Physical‐Field Nanocatalysis: Injectable Hydrogel Enables Piezo‐Photothermal Synergy for Breast Cancer Therapy

Advanced Science, EarlyView.
ABSTRACT Piezocatalytic therapy (PCT) harnesses mechanical energy to generate tumor‐lethal reactive oxygen species (ROS), but its efficacy is limited by rapid electron‐hole recombination and poor intratumoral retention. To overcome these limitations, we engineered heterostructured BiOCl@CuO nanosheets embedded in an injectable, conductive ...
