In the last years, forestry scientists have adapted genomics and next-generation sequencing (NGS) technologies to the search for candidate genes related to the transcriptomics of secondary growth and wood formation in several tree species. Gymnosperms, in particular, the conifers, are ecologically and economically important, namely, for the production of wood and other forestry end products. Un...

Airborne particles play critical roles in air quality, health effects, visibility, and climate. Secondary organic aerosols (SOA) formed from oxidation of organic gases such as α-pinene account for a significant portion of total airborne particle mass. Current atmospheric models typically incorporate the assumption that SOA mass is a liquid into which semivolatile organic compounds undergo insta...

Inter/intramolecular hydrogen bonding of a series of hydroxystearic acids (HSAs) are investigated. Self-assembly of molecular gels obtained from these fatty acids with isomeric hydroxyl groups is influenced by the position of the secondary hydroxyl group. 2-Hydroxystearic acid (2HSA) does not form a molecular dimer, as indicated by FT-IR, and growth along the secondary axis is inhibited because...

Hairy root systems are formed by transforming plant tissues with the “natural genetic engineer” Agrobacterium rhizogenes. In most plants such as Cichorium intybus L., hairy root cultures have proven to be an efficient system for secondary metabolites production. The effect of Zinc (ZnSO4), a heavy metal, was investigated at different concentrations (0, 1, 5 and 10 mM) on some secondary metaboli...

This paper examines the inter-relationship of three major phenomena- population growth, uncontrolled urban expansion and urban development in Ado Ekiti, Nigeria. Uncontrolled urban expansion has a resultant effect on the urban development of a city whereas uncontrolled urban development is caused by uncontrolled population increase is caused by Migration. This work encapsulates how population g...

This experiment was conducted to investigate the effect of drought stress and vermicompost biofertilizer on some morphological, physiological and biochemical characteristics of Thymus vulgaris in greenhouse of Khorramabad Agricultural and Natural Resources Research and Training Center in a completely randomized design with three replications. The pot experiment was performed. Factors included v...

Background and Aim: Prevalence of drug resistance in Candida albicans hinders common treatments with conventional antifungal drugs. A stockpile of research is being done to discover novel antifungal drugs. Chitosan has emerged as a promising antimicrobial and biodegradable polymer with various medical applications. The significant antimicrobial potential of some of the secondary metabolites fro...

argulus foliaceus (crustacea: branchiura), or the fish louse, is an ectoparasite of the skin or gill of the fresh water fish species. clinical signs in infected fish include scratching on aquarium walls, erratic swimming, and poor growth. it causes pathological changes due to direct tissue dam­age and secondary infections. in the present study, lionhead goldfish (carassius auratus ), taken from...

Peaceful Coexistence? The Role of Religious Schools and NGOs in the Growth of Female Secondary Schooling in Bangladesh BRAC, a non-governmental organization (NGO), runs a large number of non-formal primary schools in Bangladesh which target out-of-school children from poor families. These schools are well-known for their effectiveness in closing gender gap in primary school enrolment. On the ot...

Surface-ripened cheeses are matured by means of manual or mechanical technologies posing a risk of cross-contamination, if any cheeses are contaminated with Listeria monocytogenes. In predictive microbiology, primary models are used to describe microbial responses, such as growth rate over time and secondary models explain how those responses change with environmental factors. In this way, prim...
