Geophysical logging techniques used to support environmental site remediation. Also referred to as borehole geophysical logging and geophysical well logging, the techniques support site characterization and remedial design efforts at properties with groundwater impacted by discharges of contaminants, including Superfund (CERCLA) and other sites where dense, non-aqueous phase liquids (DNAPL) may be present in fractured bedrock and unconsolidated aquifers. The logging methods described include: Natural Gamma; Caliper; Acoustic Televiewer (ATV), also known as Acoustic Borehole Imager (ABI); Optical Televiewer (OTV), also known as Optical Borehole Imager (OBI); Electrical Resistivity, also known as Normal Resistivity; Single Point Resistance; Fluid Resistivity; Fluid Temperature; Heat Pulse Flow Meter (HPFM). Information is provided about how geophysical logs can assist in developing a Conceptual Site Model (CSM), with attention to structural geologic constraints on groundwater monitoring system design, referencing example conditions from the dipping sedimentary rocks of the Newark Basin and unconsolidated sediments of the New Jersey Coastal Plain. The presentation is meant to be of use to a wide range of investigators, including geologists, hydrogeologists, engineers and regulators responsible for site remediation.

New Soil Investigation
The document discusses soil investigation for determining appropriate foundation types and capacities. It describes conducting field tests and collecting lab samples to characterize soil properties, profile, and bearing capacity. Common soil colors are outlined. Methods of soil exploration include test pits, borings, and geophysical techniques. Problems with expansive black cotton soils are explained. Design considerations for shallow foundations and pile foundations are covered.

Chapter 2 Laplace Transform
This document discusses Laplace transforms and their applications in control systems. It begins by defining the Laplace transform and explaining how it can be used to solve differential equations by transforming them from the time domain to the complex frequency domain. It then provides several properties and formulas for Laplace transforms, including derivatives, integrals, time shifts, and partial fraction decomposition. Examples are given to demonstrate finding the Laplace transform of common functions and taking the inverse Laplace transform. The document concludes by explaining how Laplace transforms can be used to analyze control systems modeled by integrodifferential equations.
Types of samplers used in soil sampling
There are two types of soil samples:
1. Disturbed samples - The natural structure of the soil is modified or destroyed during sampling.
2. Undisturbed samples - The natural structure and properties of the soil remain preserved.
Soil sampling devices include open drive samplers, piston samplers, and rotary samplers. Open drive samplers use thin-walled tubes that are pushed into the soil to collect undisturbed samples. Piston samplers also use thin-walled tubes but have a piston inside to prevent excess soil from entering and maintain sample integrity. Rotary samplers have an outer rotating barrel and inner stationary tube to collect annular ring samples.
1)methods of exploration
This document discusses subsoil exploration, which involves collecting soil data through field and laboratory investigations to assess soil properties at a site. The main objectives are to determine the nature, depth, thickness, and extent of soil strata, as well as groundwater depth and properties. Exploration methods include direct techniques like test pits and borings, and indirect techniques like sounding tests and geophysical methods. Standard penetration tests are commonly used to determine properties of cohesionless soils by counting blows required to penetrate the soil. Corrections are applied to penetration values to account for overburden pressure and sample dilatancy.
Laplace transforms
This document provides an overview of Laplace transforms. Key points include:
- Laplace transforms convert differential equations from the time domain to the algebraic s-domain, making them easier to solve. The process involves taking the Laplace transform of each term in the differential equation.
- Common Laplace transforms of functions are presented. Properties such as linearity, differentiation, integration, and convolution are also covered.
- Partial fraction expansion is used to break complex fractions in the s-domain into simpler forms with individual terms that can be inverted using tables of transforms.
- Solving differential equations using Laplace transforms follows a standard process of taking the Laplace transform of each term, rewriting the equation in the s-domain, solving
Higher Differential Equation
1) Ordinary differential equations relate a dependent variable to one or more independent variables by means of differential coefficients. They can be classified based on order, degree, whether they are linear or non-linear, and type (exact, separable variables, homogeneous).
2) First order differential equations can sometimes be solved by separation of variables, or by finding an integrating factor. Homogeneous equations can be transformed by substitution.
3) Second order linear differential equations can be reduced to a system of two first order equations. The complementary function and particular solutions combine to form the general solution. Unequal or equal roots of the characteristic equation determine the form of the complementary function.

Sl282 optv review
The well had been inspected twice previously using optical and caliper logging tools, which identified major fractures between 61-68m that caused the tools to become stuck. On the current inspection, the optical and caliper tools again became stuck in the same fractures between 61-66m. The conclusion is that the previously observed major fractures still exist and prevented a submersible pump from being installed at 70m. A rigid hose may have helped navigate past the fractures instead of the flexible hose used.
Sk201 optv review
The document reviews OPTV data collected from a well on April 20, 2010 to check the status of the well's deviation and verticality after having issues pushing and pulling rods at a depth of 202m. It finds that the steel casing ends around 34.9m, there is a possible major fracture around 43.4m, and at 174.5m the well deviation is 10.6 degrees or 12m off vertical. The conclusion is that the well's lack of verticality may be contributing to the difficulty operating the rods deeper than 175m.
Klt001 elog tcgs_qc
Both the TCGS and ELOG sondes detected a possible clay layer at 14m depth. The TCGS sonde experienced a bad conductivity reading from 26-34m depth likely due to clay infiltrating the nose of the sonde and causing a bad contact. While the gamma readings from both tools were reliable, the conductivity readings from the TCGS sonde were questionable below 25m depth due to the potential bad contact issue.

The gamma log collected at KSG007 between depths of 20-30m showed low readings and a spike, raising doubts from ONWater. A comparison gamma log from a nearby well, KSG008, showed similar features between depths of 13-23m, indicating the anomalies were likely due to subsurface geology rather than issues with the logging tools. It was concluded a rerun of the log was unnecessary.
Sl282 optv review
The document reviews optical televiewer (OPTV) and caliper log data collected from a well on March 5, 2010. The data indicates there are major fractures between depths of 61-68 meters that caused equipment to get stuck previously. Both the OPTV and caliper logs from the current and previous logs show blurry images and diameters over 14 inches at these fracture locations. The conclusion is that the fractures between 60-68 meters have existed since well completion and no new blockages were observed, but a rigid hose may have helped maneuver past the fractures instead of the flexible hose that was used.

一比一原版(QMUE毕业证书)英国爱丁堡玛格丽特女王大学毕业证文凭如何办理
永久可查学历认证【微信：A575476】【(QMUE毕业证书)英国爱丁堡玛格丽特女王大学毕业证成绩单Offer】【微信：A575476】（留信学历认证永久存档查询）采用学校原版纸张、特殊工艺完全按照原版一比一制作（包括：隐形水印，阴影底纹，钢印LOGO烫金烫银，LOGO烫金烫银复合重叠，文字图案浮雕，激光镭射，紫外荧光，温感，复印防伪）行业标杆！精益求精，诚心合作，真诚制作！多年品质 ,按需精细制作，24小时接单,全套进口原装设备，十五年致力于帮助留学生解决难题，业务范围有加拿大、英国、澳洲、韩国、美国、新加坡，新西兰等学历材料，包您满意。
【业务选择办理准则】
一、工作未确定，回国需先给父母、亲戚朋友看下文凭的情况，办理一份就读学校的毕业证【微信：A575476】文凭即可
二、回国进私企、外企、自己做生意的情况，这些单位是不查询毕业证真伪的，而且国内没有渠道去查询国外文凭的真假，也不需要提供真实教育部认证。鉴于此，办理一份毕业证【微信：A575476】即可
三、进国企，银行，事业单位，考公务员等等，这些单位是必需要提供真实教育部认证的，办理教育部认证所需资料众多且烦琐，所有材料您都必须提供原件，我们凭借丰富的经验，快捷的绿色通道帮您快速整合材料，让您少走弯路。
留信网认证的作用:
1:该专业认证可证明留学生真实身份
2:同时对留学生所学专业登记给予评定
3:国家专业人才认证中心颁发入库证书
4:这个认证书并且可以归档倒地方
5:凡事获得留信网入网的信息将会逐步更新到个人身份内，将在公安局网内查询个人身份证信息后，同步读取人才网入库信息
6:个人职称评审加20分
7:个人信誉贷款加10分
8:在国家人才网主办的国家网络招聘大会中纳入资料，供国家高端企业选择人才
→ 【关于价格问题（保证一手价格）
我们所定的价格是非常合理的，而且我们现在做得单子大多数都是代理和回头客户介绍的所以一般现在有新的单子 我给客户的都是第一手的代理价格，因为我想坦诚对待大家 不想跟大家在价格方面浪费时间
对于老客户或者被老客户介绍过来的朋友，我们都会适当给一些优惠。
选择实体注册公司办理，更放心，更安全！我们的承诺：可来公司面谈，可签订合同，会陪同客户一起到教育部认证窗口递交认证材料，客户在教育部官方认证查询网站查询到认证通过结果后付款，不成功不收费！
