The Laws of Securities Lawyering After Sarbanes-Oxley

Drilled foundations are often considered to be a standard method of installation of steel core piles and similar foundation components in sensitive environments such as urban areas where other common technologies such as stranding or diging cannot be applied. Much research has been made in the area of how the piles interact in the clay. BESAB, who are specialists within underpinning, have observed that it takes time for a house to settle after an underpinning. There are uncertainties when it comes to how the house adapts to an underpinning. During interviews experts have given many different possible explanations but it seems to be a lack of knowledge in the area. All agree that it takes a couple of years for a house to adapt to an underpinning. The recommendation is to wait at least 2 years before proceed with the work in the house. In the project that has been studied in this research, precision leveling points have been measured 2-3 times a week to monitor the settlements throughout the project. The measurements have shown a greater settlement on the street level than in the basement, 2 floors down from the street level during the same amount of time which lead to the question: What are the effects of underpinning in a house? The major reason for that settlement has occurred in the area is that the foundation, consisting of wooden piles, has lost its carrying capacity due to the lowered ground water level. During underpinning the house is mostly affected by dynamic forces. The structure gets temporary weakened when holes are made in walls for beams and drilling is made in already sensitive foundation. The fixated parts of the structure, where the load transferring elements are already installed between the pile and the structure, can get locally loaded when drilling is made in adjacent areas. After underpinning the house with its weight is settling on the piles. The house has to adapt to a new mode of action. This can be done either by just leaving the house and wait for the piles to take load and get compressed or by pre-load the piles with the expected final load of the house to avoid the time for the compression of the piles. The greatest risk linked to this phenomenon is that new cracks can occur due to post settlements and in worst case in an elevator shaft or in the water proofing in bathrooms or kitchen. If renovation work starts before the house have stopped settle than the risk is big that cracks will occur in the newly renovated areas resulting in that the renovation have to be re-done. 4 Effective communication is essential to assess risks involved with an underpinning and to avoid tensions between actors involved in an underpinning project if damage due to post settlement will occur. The problem investigated in this report is translated in to Kuhn’s theory on science the beginning of the crisis. Further research is required to develop the empirics in to theory. Accurate measurements must be collected and these must be processed in mathematical statistics. Models must be built and existing theories within structural- and geotechnical engineering must be studied in further depth to be able to state a new paradigm in this area

HyperCLOVA X Technical Report

We introduce HyperCLOVA X, a family of large language models (LLMs) tailored to the Korean language and culture, along with competitive capabilities in English, math, and coding. HyperCLOVA X was trained on a balanced mix of Korean, English, and code data, followed by instruction-tuning with high-quality human-annotated datasets while abiding by strict safety guidelines reflecting our commitment to responsible AI. The model is evaluated across various benchmarks, including comprehensive reasoning, knowledge, commonsense, factuality, coding, math, chatting, instruction-following, and harmlessness, in both Korean and English. HyperCLOVA X exhibits strong reasoning capabilities in Korean backed by a deep understanding of the language and cultural nuances. Further analysis of the inherent bilingual nature and its extension to multilingualism highlights the model's cross-lingual proficiency and strong generalization ability to untargeted languages, including machine translation between several language pairs and cross-lingual inference tasks. We believe that HyperCLOVA X can provide helpful guidance for regions or countries in developing their sovereign LLMs.Comment: 44 pages; updated authors list and fixed author name

Investigation of Epoxidized Palm Oils as Green Processing Aids and Activators in Rubber Composites

Epoxidized palm oil (EPO) is environmentally friendly, biodegradable, and a relatively less costly processing aid. In this study, we investigated the suitability of EPO in place of aromatic processing oils in styrene butadiene rubber. The curing properties, mechanical properties, abrasion resistance, and heat buildup properties of rubber composites with EPO were compared with those of the standard with aromatic oils. The rubber composites with EPO showed enhanced mechanical properties including modulus, tensile strength, and elongation at break. This is ascribed to the improved dispersion of fillers in the rubber matrix and interaction between the filler and the polymer. Furthermore, EPO in the rubber matrix showed remarkable abrasion resistance, rebound resilience, and heat buildup at low loadings. EPO in a rubber composite presents feasibility as a renewable raw material that can serve as an alternative to petrochemical oils in various applications
