Geothermal resources are rich in the Guangdong-Hong Kong-Macao Greater Bay Area, South China. The spatial distribution characteristics of geothermal anomalies can provide scientific supports for evaluating geothermal resources potential and decision-making on geothermal exploration and development in the Greater Bay area. Based on geographic information systems (GIS) technology, spatial data layers including terrestrial heat flow, granite distribution, fault, Bouguer gravity anomaly, aeromagnetic anomaly, and Curie depth were constructed, and their spatial correlations to geothermal anomalies were analyzed. The results show that geothermal anomalies are favorably located in the areas of heat flow value greater than 75 mW/m2, Yanshaian granite bourdary or interior, distance less than 3 km form a major fault, Bougue gravity anomaly gradient greater than 1. 6 mGal/km, aeromagnetic anomaly value of -5~5 nT, and Curie depth smaller than 15 km. The occurrence of strong geothermal anomalies is most closely related to Curie depth, Yanshanian granites and major faults. On the basis of the constructed data layers and the classification of their geothermal anomaly relevancies, two methods for predicting mineral resources, namely the weights of evidence (WoE) model and the weighted information value (WIV) model, were employed to integrate and analyze the multivariate spatial information for geothermal resources prospect. This study shows that lower mountainous or hilly areas with widespread distribution of Yanshanian granite and high rock thermal conductivity are prone to strong geothermal anomalies. The western Jiangmen, central Zhaoqing, northeastern Guangzhou, northeastern Huizhou, and Shenzhen are of these characteristics. They are considered as high-potential geothermal resource areas in the Greater Bay area. [ABSTRACT FROM AUTHOR]

Disputes over Ovid's genuine attitudes towards Roman emperor Octavian have never ceased among Western scholars of classics. Never a motivated dissident, Ovid was unfortunately an adherent to the idea of artistic autonomy, which, against the backdrop of a unified Augustan cultural order, was interpreted by the imperial family as a political stance. In order to return to Rome or suffer less severely, the banished poet would have to appease the emperor with servile penitence, but Ovid was frequently impelled by his obstinacy as an artist and indignation at his unmerited torments to overlook his real-life needs and give his works an ironic twist. While in some poems, his venom of criticism is ingeniously dissimulated beyond easy detection, his defiance is alarmingly obvious in others. Although Octavian, Livia, and Tiberius usually appear as gods in Tristia and Ex Ponto, they are revealed, through various means of artistry, to be no more than ruthless rulers on earth whose self-imposed apotheosis is constantly ridiculed.

Objective: To investigate the effects of experimental varicocele on mitochondria calcium and cytochrome C of the epididymal cells in adolescent rats., Methods: Forty male adult Wistar rats were divided into two groups randomly: varicocele group (VG) and sham operation group (SOG) by partial ligation or exposure of the left renal vein. Bilateral epididymides were removed after ten, Results: The content of mitochondria weeks. Mitochondria calcium and cytochrome C levels of the epididymal cells were detected. calcium decreased (P < 0.001 ) while that of cytochrome C increased (P < 0.05) markedly in the experimental group compared with SOG., Conclusion: Calcium dyshomeostasis and mitochondrial damage of the epididymal cells caused by varicocele may play an important role in leading to subfertility.
