Reservoir Characteristics and Influencing Factors of the Jurassic Yan'an Formation in the Hao Tan Area of the Ordos Basin
Get PDFTo study the reservoir characteristics and main controlling factors of Jurassic Yan'an formation in Hao Tan area of Ordos Basin. The reservoir characteristics and its main controlling factors were revealed by the experimental observations such as rock sheet analysis, high pressure mercury pressure experiment and cathodoluminescence. The Jurassic reservoirs in Hao Tan area are mainly located in Yan 10~Yan 8 section.The results show that the main types are feldspathic sandstone and feldspathic quartz sand with medium to low maturity, and the main types of pores include intergranular pores, intergranular dissolution pores and feldspathic dissolution pores. The physical properties of the reservoir are dominated by mesopore mesoturbidity, with medium throat radius and low drainage pressure. The reservoir has experienced moderate to strong mechanical compaction with various types of cementation dominated by carbonate, siliceous and clay minerals, among which the pore structure of the reservoir has been significantly improved by dissolution. The reservoirs of the Yan'an Formation have certain storage capacity and development potential, especially the Yan 10 and Yan 8 reservoirs have better physical properties, and the sedimentation and diagenesis have affected the inhomogeneity of the reservoirs. It is concluded that the Yan 8 reservoir (72% class II) and the local sweet spot of Yan 10 (class I porosity >16%) have development potential, but different development strategies should be formulated for the high permeability zone of Yan 9. The results of the study can provide a theoretical basis for the exploration and development of the same type of Jurassic tight sandstone reservoirs in the Ordos Basin

The Effect of Occlusal Adjustment on Periodontal Treatment Outcomes in Patients with Chronic Periodontitis and Occlusal Trauma
Get PDFObjective: To investigate the effect of occlusal intervention combined with basic periodontal treatment on patients with chronic periodontitis complicated by occlusal abnormalities, and to provide evidence-based support for clinical practice. Methods: Sixty patients with chronic periodontitis accompanied by occlusal dysfunction who visited our hospital from January to December 2023 were selected as study samples and randomly divided into an experimental group (n=30) and a control group (n=30). The control group received standard periodontal basic treatment (including supragingival cleaning, subgingival scaling, and root planing), while the experimental group received additional occlusal function correction (involving early contact point modification, elimination of occlusal interference, and reconstruction of occlusal stability) based on the standard treatment. The periodontal status indicators (including probing depth PD, attachment level AL, and gingival bleeding index GBI) and overall treatment efficacy were evaluated in both groups before and after 3 months of treatment. Results: Before treatment, there were no significant differences in the detection data of periodontal probing depth (PD), attachment loss (AL), and gingival bleeding index (GBI) between the two groups (P>0.05). After 3 months of treatment, the experimental group showed significantly better results in terms of PD, AL, and GBI compared to the control group, with statistically significant differences (P<0.05). Additionally, the overall treatment efficacy rate in the experimental group was significantly higher than that in the control group (P<0.05). Conclusion: For patients with chronic periodontitis complicated by occlusal trauma, occlusal adjustment intervention supplemented with standard periodontal treatment can effectively improve the health status of periodontal tissues and significantly enhance clinical efficacy. It is worth promoting and applying in clinical practice
Peanut Production in Central Luzon, Philippines: An Assessment of Farmer Practices, Challenges, and Profitability
Get PDFPeanut is a crucial leguminous crop grown by farmers in Central Luzon, acknowledged for its economic and ecological significance. Peanuts function as a versatile rotation crop, thriving in warm regions with well-drained, sandy or loamy soils, and significantly contribute to sustainable farming methods by enhancing soil fertility. Central Luzon, recognized as a key peanut-producing area in the Philippines, significantly contributes to fulfilling the demand for this crop. Nonetheless, numerous challenges remain, obstructing the growth and productivity of the industry. Farmers in the region encounter challenges including restricted access to premium seeds, dependence on conventional farming techniques, and vulnerability to pests and diseases. Due to insufficient support for training, extension services, and research funding, the identified challenges result in decreased yields and variable production quality. Mechanization, especially in the context of labor-intensive harvesting, is still not fully developed, resulting in smallholder farmers relying on inefficient and time-consuming methods.
This paper presents a thorough evaluation of peanut production in Central Luzon, including an analysis of farms and farmers, an assessment of production costs and returns, identification of constraints, proposed interventions, and a review of current research and development initiatives. Notable challenges encompass restricted access to high-quality seeds, inadequate training and extension support, and a deficiency in mechanized post-harvest equipment. The demanding processes of planting, weeding, and harvesting significantly constrain the growth of peanut production areas and overall yields. To effectively address these gaps, it is essential to foster collaboration among stakeholders. This includes the development of suitable machinery for small farm holdings, the implementation of training programs, and the enhancement of investment in peanut research and extension
