Petrol
'Petrol' is a prose poem disguised as a novella of adolescence in County Cork. With its dizzy pace and perfect narrative timing, as well as uncanny portraits of its characters, it is a unique work and a remarkable departure for a writer whose poetry is widely appreciated for its humour and uncompromising depiction of rural Ireland.

Predicting Porosity in Raw Cork Using Near-Infrared Spectroscopy
The classification of cork planks as a raw material is traditionally performed through visual inspection of cork pores and defects, both in forest owners’ associations and industrial settings. This method introduces subjectivity and limits reproducibility. This study aimed to develop near-infrared spectroscopy (NIRS) models for predicting porosity in raw cork, distinguishing virgin, secondary, and mature cork types. A total of 156 cork samples representing the three cork types were analyzed. Spectra were collected on the transverse and radial surfaces using a Bruker MPA spectrophotometer. Partial Least Squares Regression (PLS-R) models were developed separately for each cork type, yielding cross-validated coefficients of determination (R2) between 0.48 and 0.64. Additionally, two global models were obtained using a random data split (60% for cross-validation and 40% for validation), differentiated by whether or not areas corresponding to insect galleries were included. The model incorporating insect galleries achieved R2 values of 0.63 (cross-validation) and 0.46 (validation), while the model excluding them yielded R2 values of 0.51 and 0.52, respectively. The final optimized model, based on all samples and using selected spectral regions (9500–7500 and 6100–5450 cm−1) with first derivative and vector normalization preprocessing, achieved an R2 of 0.61, RMSECV of 0.025, and RPD of 1.6 using five latent variables. This model was used to estimate porosity coefficients in visually classified secondary and mature cork. Results confirmed an inverse relationship between porosity and cork quality class: higher-quality classes (Q1, Q2) had lower porosity, with Q1 being the most homogeneous. Porosity increased from Q2 to Q6 in mature cork, expressing declining quality. Greater variability in lower-quality classes highlights porosity’s relevance for classification. These results demonstrate the potential of NIRS as a non-destructive tool for assessing cork porosity, offering a more objective and efficient alternative to conventional methods.

Broken angels
One cold spring morning in County Cork, two fishermen find a bundle of rags floating in the Blackwater River. It is the bloated body of Father Heaney. His hands and feet are bound, and his neck bears the marks of garrotting wire. Worse still, he has been castrated. When a second priest is found murdered, his body bruised and beaten and the same savage wound hidden beneath his soutane, Detective Inspector Katie Maguire finds evidence of a sinister cover-up at St Joseph's Orphanage. But the Catholic diocese still wields considerable power here, and the Garda are under pressure to close the case. Katie has to work alone if she is to catch the killer in time - but first she must shatter a wall of silence that for decades has hidden a terrible secret. A secret that is beyond belief...

Qualitative anatomical characteristics of the virgin cork in Quercus variabilis grown in Korea
To provide information on the identification and quality evaluation of Q. variabilis virgin cork from Korea, the qualitative anatomical characteristics of the virgin cork were observed by optical and scanning electron microscopy and compared with those of Q. suber reproduction cork from Portugal. Q. variabilis showed a narrower growth ring than Q. suber. A dark-brown zone with sclereids was found only in Q. variabilis cork. The lenticular channel in Q. variabilis is larger than that in Q. suber. Q. variabilis virgin cork showed a distinct growth ring boundary and an abrupt transition from earlycork to latecork with a few rows of latecork cells. Q. suber reproduction cork showed an indistinct growth ring with a gradual transition from one to two rows of latecork cells. In the earlycork, Q. suber showed mild corrugation, while Q. variabilis displayed significant corrugation with collapsed and distorted cork cells. The lenticular channel in Q. variabilis virgin cork was surrounded by thick-walled cells filled with compact lenticular filling tissue. Q. suber reproduction cork had an opening with loose lenticular filling tissue surrounded by thick-walled cells. Prismatic crystals, thick-walled sclereid cells, and fiber-sclereids were found only in Q. variabilis. A few trabeculae were found in both cork samples.

Modeling cork yield, thickness, price, and gross income in the portuguese cork oak montado
The cork oak (Quercus suber L.) woodlands, known as montados in Portugal, hold significant economic, cultural, social, and environmental value. They are found in the Mediterranean Sea basin, particularly in the Iberian Peninsula, and sustain various activities like silvopastoralism, with cork being a primary product. Despite its economic significance, challenges such as climate change threaten its sustainability. This study aimed to analyze the edaphoclimatic variables affecting cork yield, thickness, price, and gross income in the Alentejo region of Portugal. A total of 35 farmers were selected for the data collection included in this study. Multivariable linear regressions were performed to establish relationships between cork yield, thickness, price, and gross income as dependent variables, various edaphoclimatic factors, and tree densities. A higher tree density correlates with an increased cork yield but a decreased cork thickness. Soil pH affects cork yield and thickness, with a lower pH favoring higher cork yields but thinner cork. A higher clay and silt content in horizon soil C enhances cork thickness and raises the price but reduces the cork yield. Higher accumulated precipitation and temperatures contribute to higher yields and thicknesses of cork. It is concluded that the relationships between the dependent and the independent variables are complex but partially explainable. Understanding these relationships is paramount to ensure sustainable management practices are adopted that are capable of addressing issues raised in the current context of climate change.

Quantile regression for modelling the impact of climate in cork growth quantiles in Portugal
The annual growth and the thickness of cork are known to be highly variable between trees located in the same geographical location. Researching how climate variables affect different trees within the same site is a step forward for the management of cork production since current knowledge focusses only on the average tree response. Quantile regression methodology was applied for the first time to a large data set containing measurements of cork growth, sampled in 35 stands across the cork oak distribution area in Portugal. This methodology proved to be useful for testing the hypothesis raised: does climate affect differently the annual cork growth, and ultimately cork thickness of individual trees located in the same stand? Estimating the amount of cork produced by one stand that has the required thickness for the production of natural cork stoppers is essential to support cork oak management. However, no model, before this work, had been developed to provide managers with this information. A downward parabolic relationship between annual cork growth and annual precipitation was determined for all quantiles, with optimum annual average precipitation value ranging from 1103 to 1007 mm. April to August monthly temperatures, spring average temperature or summer average temperature, showed a negative relationship with annual cork growth, in particular for lower quantiles. Maximum annual temperature was shown to negatively affect annual cork thickness, in particular for the trees under the 6th quantile. The ratio between annual precipitation and average temperature, that define the Lang index (LI), showed a downward parabolic relationship with annual cork growth. Best cork growth conditions are found for Lang index values around 60, corresponding for the transition between semi-arid climate and humid climate. The application of the final model developed for estimating cork thickness of an eight years’ cork growth period allowed the prediction and mapping of the percentage of cork suitable for natural cork stopper production. It showed that higher values are expected in the Southern and Central coastal regions and along the Tagus River basin. The Northern coastal and mountain regions, characterised by Lang index values higher to 60 (humid climates), present lower estimated values for the percentage of cork suitable for natural cork stopper production. The estimated values are expected to be reduced under climate change scenarios in the Southern and Central coastal regions.
