ABSTRACT First Person is a series of interviews with the first authors of a selection of papers published in Biology Open, helping early-career researchers promote themselves alongside their papers. Natalí Delorme and Leonardo Zamora are co-first authors on ‘ A new method to localise and quantify oxidative stress in live juvenile mussels’, published in BiO. They are both researchers in the laboratory of Serean Adams at the Cawthron Institute, Nelson, New Zealand. Natalí's research interests centre around ecophysiology of marine invertebrates, particularly on the organisms' stress response. Leonardo is investigating the biology of commercially, ecologically and culturally relevant marine invertebrates throughout their life cycle.

Abstract Gas turbines are most widely used for power generation and operate under various conditions and loads. Gas turbine control is important to cope with various situations, and the turbine inlet temperature (TIT) is the most important parameter because it is directly related to the power output and life cycle of the turbine. Thus, precise prediction and control of the TIT are important in terms of the stable operation and life cycle management of gas turbines. This paper proposes a new method to predict non-measured parameters such as the air flow and TIT using Kalman filter techniques. The Kalman filter is widely used for estimating the instantaneous state of a system and can estimate non-measured parameters. The Kalman filter algorithm was implemented in a gas turbine analysis program using MATLAB. The reliability of the new method was verified through various case studies using virtual data and real operating data. The results were compared with those of a model-based gas turbine diagnostics program. The computing time of the Kalman filter and model-based diagnostics program were also compared to confirm the capability of the new method. The results indicate that the new method is more suitable for diagnostics and monitoring applications than the model-based analysis program. Finally, two case studies were performed to confirm the feasibility of the new method using two virtual datasets. The results confirm that the Kalman filter can predict the non-measured parameters precisely.

Abstract Recent timelapse microscopy studies suggest that endospore forming bacteria encounter a quantity-quality tradeoff: Bacillus subtilis can either make more or better spores. Natural isolates employ different life-cycle strategies that are beneficial under different revival conditions. These findings have implications for our understanding of the ecology and evolution of sporulating bacteria and their use in biotechnological applications.

A new method of determining the duration of the aquatic stages of Anophelines in nature is described. Repeated daily dippings of a stretch of stream were made, and the numbers of pupae and of larvae of each instar were recorded. The duration of the aquatic stages was then determined by analysis of the sequences of peaks in these numbers.The duration of larval life of A. minimus, when living in a stream at an average daily range of water temperature between 26·5°C. and 30·6°C, was seven days.The full life cycle of A. minimus, under monsoon conditions in Assam, probably occupied 14 days—egg 2 days, larva 7 days, pupa 2 days, adult to first egg-laying 3 days.

ABSTRACT In Podospora anserina previous investigations showed that mutations in genes involved in the control of protoplasmic incompatibility cause defects at various stages of differentiation during the life cycle and also modify properties of the plasma membrane. To establish these relationships in another way, a new method for screening mutations has been developed as a first step. Eighty-five new mutants were selected for resistance to toxic products (sorbose or thiourea); in a second step these mutants were tested for modifications of protoplasmic incompatibility and cellular differentiation. Seven of the sorbose or thiourea resistant-mutants (i.e., 8%) exhibited new patterns of protoplasmic incompatibility. Genetic analyses were carried out with three mutants. Mutation X25 suppresses protoplasmic incompatibility resulting from all allelic interactions and restores the fertility of the crosses ♀ V × ♂ V1 and ♀ Z1 × ♂ Z2. Mutation V41 is an allele of the v locus with new properties. Mutation X61 totally suppresses the V/V'1 interaction and weakens all of the other allelic incompatibility systems; X61 strains are defective in protoperithecia differentiation. Electrophoresis of plasma membrane proteins showed that X61 strains lack two polypeptides whose apparent molecular weights are 41,000 and 44,000. This new screening method is especially efficient for obtaining new mutants and identifying additional genes involved in incompatibility. These results provide further support demonstrating the relationships between protoplasmic incompatibility, cellular differentiation and plasma membrane.
