Investigation and analysis of rural drinking water nitrate pollution in Donggang District,Rizhao City

Objectives To understand the distribution of nitrate in different types of water in our district and provide evidence for a need to improve water quality and water quality control in the rural area.Methods Surface water of 25 small central water supply systems(including source water and tap water) and tap water of 40 wells were collected.Monitoring and statistical analysis were performed.Results Among all types of rural area water in 2013,well water had the highest nitrate content.The average nitrate content was 15.6 mg / L,close to the ≤20mg / L standard for daily drinking water middle and small-sized central water supply systems(GB 5749-2006).The failure rate standard is ≤20.00%.Among the 90 water samples,12 failed to meet the standard,a failure rate of 13.33%.Though it is a water source,surface water had a similar nitrate content to tap water.Water treatment yielded an average nitrate removal rate of 0.49%.Conclusion The nitrate content of all types of water was excessive.Water sources should be carefully selected and water management should be strengthened.
Encouraging a Positive Outlook: The Benefits of Appreciative Inquiry in a Theological Library

Librarians face a future of rapid and disconcerting change, and it is increasingly important to address this change in a constructive way. In contrast to problem-solving approaches which focus on the negative, Appreciative Inquiry helps staff recognize the good attributes of their organization and explore ways to build on those strengths for the future. This study investigated the application of Appreciative Inquiry in the context of a theological library at Trinity International University. Interviews and a summit meeting were held with staff to elicit positive characteristics of the library and their jobs. These results were then used to suggest proposals for the future. The process itself is a useful way to transform the culture of a library and create an environment that welcomes positive change.
Observations on the phagic response of the pig to infusions of dextrose and sodium pentobarbital into the ventromedial area of the brain.

Summary Infusion of sodium pentobarbital into the lateral and the ventral areas of the hypothalamus inhibited or increased food intake respectively. This is consistent with the existence of ‘satiety’ and feeding’ centres in swine. Neither glucose implantation nor infusion into the ventromedial area of the hypothalamus nor peripheral glucose infusions altered the daily food intake of hungry pigs.
Coulomb Interactions Among Free Carriers

Going beyond the Hartree and Hartree–Fock approximations, this chapter deals with fluctuations of an electron gas away from the mean-field approximation. Having introduced the basic distinction between collective effects at long wavelength (plasmons) and single-particle interactions at short range, we derive the short-range interparticle scattering rate and discuss its implementation in the study of electron transport. We also discuss the interband process of impact ionization. We conclude with a brief discussion of band-gap narrowing, a related Coulomb effect at high density.
Panic Diaries: A Genealogy of Panic Disorder

Part cultural history, part sociological critique, and part literary performance, Panic Diaries explores the technological and social construction of individual and collective panic. Jackie Orr looks at instances of panic and its “cures” in the twentieth-century United States: from the mass hysteria following the 1938 radio broadcast of H. G. Wells’s War of the Worlds to an individual woman swallowing a pill to control the “panic disorder” officially recognized by the American Psychiatric Association in 1980. Against a backdrop of Cold War anxieties over atomic attack, Orr highlights the entanglements of knowledge and power in efforts to reconceive panic and its prevention as problems in communication and information feedback. Throughout, she reveals the shifting techniques of power and social engineering underlying the ways that scientific and social scientific discourses—including crowd psychology, Cold War cybernetics, and contemporary psychiatry—have rendered panic an object of technoscientific management. Orr, who has experienced panic attacks herself, kept a diary of her participation as a research subject in clinical trials for the Upjohn Company’s anti-anxiety drug Xanax. This “panic diary” grounds her study and suggests the complexity of her desire to track the diffusion and regulation of panic in U.S. society. Orr’s historical research, theoretical reflections, and biographical narrative combine in this remarkable and compelling genealogy, which documents the manipulation of panic by the media, the social sciences and psychiatry, the U.S. military and government, and transnational drug companies.
Importance of Macromonomer Quality in the Ring-Opening Metathesis Polymerization of Macromonomers

Various macromonomers (MMs) were synthesized using controlled radical polymerization (CRP) by either directly growing from a norbornene-functionalized initiator or chain transfer agent (“direct-growth” or DG method) or coupling a norbornenyl group to preformed polymers (“growth-then-coupling” or GC method). The degree of control for the ring-opening metathesis polymerization (ROMP) of these MMs was found to be dependent on which synthetic method was used for the MMs. Narrowly dispersed brush polymers were consistently obtained from the GC-MMs. In contrast, the DG-MMs resulted in brush polymers with a small high-molecular weight (MW) shoulder or broader molecular weight distribution (MWD). Matrix-assisted laser desorption ionization time-of-flight mass spectrometry of DG-MMs showed the presence of a small amount of α,ω-dinorbornenyl telechelic species resulting from the biradical combination during polymerization. A control study further revealed that even the presence of 1 mol % α,ω-norbornenyl telechelic...
Tornado fragility and risk assessment of an archetype masonry school building

Abstract Tornadoes are a low-occurrence high-consequence hazard and not only threaten the life safety of building occupants but have recently resulted in billions of dollars in direct and indirect damages for single events. Design codes do not consider tornado loads for building and other structures (with the exception of nuclear facilities) because the occurrence rate has historically been considered too low. The advent of performance-based seismic design has revolutionized the engineering thought process and as a result building owners can consider performance objectives that enable a building to perform better in an extreme hazard than observed with current design code. In this paper, the performance of a masonry school building subjected to tornado wind loads is investigated using a fragility methodology. The tornado fragility assessment methodology is described along with proposed damage states for consideration in loss estimation. An array of masonry material types are considered based on the Masonry Standards Joint Committee (MSJC) code to enable applicability of the fragilities developed herein for a range of designs throughout the United States.
Structure–Activity Relationships of the MEPicides: N-Acyl and O-Linked Analogs of FR900098 as Inhibitors of Dxr from Mycobacterium tuberculosis and Yersinia pestis

Despite continued research efforts, the threat of drug resistance from a variety of bacteria continues to plague clinical communities. Discovery and validation of novel biochemical targets will facilitate development of new drugs to combat these organisms. The methylerythritol phosphate (MEP) pathway to make isoprene units is a biosynthetic pathway essential to many bacteria. We and others have explored inhibitors of the MEP pathway as novel antibacterial agents. Mycobacterium tuberculosis, the causative agent of tuberculosis, and Yersinia pestis, resulting in the plague or “black death”, both rely on the MEP pathway for isoprene production. 1-Deoxy-d-xylulose 5-phosphate reductoisomerase (Dxr) catalyzes the first committed step in the MEP pathway. We examined two series of Dxr inhibitors based on the parent structure of the retrohydroxamate natural product FR900098. The compounds contain either an extended N-acyl or O-linked alkyl/aryl group and are designed to act as bisubstrate inhibitors of the enzyme...

Mechanistic insight of platelet apoptosis leading to non-surgical bleeding among heart failure patients supported by continuous-flow left ventricular assist devices

Non-surgical bleeding (NSB) is the most common clinical complication in heart failure (HF) patients supported by continuous-flow left ventricular assist devices (CF-LVADs). In this study, oxidative stress and alteration of signal pathways leading to platelet apoptosis were investigated. Thirty-one HF patients supported by CF-LVADs were divided into bleeder (n = 12) and non-bleeder (n = 19) groups. Multiple blood samples were collected at pre-implant (baseline) and weekly up to 1-month post-implant. A single blood sample was collected from healthy subjects (reference). Production of reactive oxygen species (ROS) in platelets, total antioxidant capacity (TAC), oxidized low-density lipoproteins (oxLDL), expression of Bcl-2 and Bcl-xL, Bax and release of cytochrome c (Cyt.c), platelet mitochondrial membrane potential (Δψ m), activation of caspases, gelsolin cleavage and platelet apoptosis were examined. Significantly elevated ROS, oxLDL and depleted TAC were evident in the bleeder group compared to non-bleeder group (p < 0.05). Platelet pro-survival proteins (Bcl-2, Bcl-xL) were significantly reduced in the bleeder group in comparison to the non-bleeder group (p < 0.05). Translocation of Bax into platelet mitochondria membrane and subsequent release of Cyt.c were more prevalent in the bleeder group. Platelet mitochondrial damage, activation of caspases, gelsolin cleavage, and ultimate platelet apoptosis in the bleeder group were observed. Oxidative stress and activation of both intrinsic and extrinsic pathways of platelet apoptosis may be linked to NSB in CF-LVAD patients. Additionally, biomarkers of oxidative stress, examination of pro-survivals and pro-apoptotic proteins in platelets, mitochondrial damage, caspase activation, and platelet apoptosis may be used to help identify HF patients at high risk of NSB post-implant.
1.19 – How Much is Enough or Too Little: Assessing Healthcare Demand in Developed Countries

The problem of healthcare demand in developed countries is a complicated one, very much a function of the affluence of a country, individual preferences and desires, and changing notion of what counts as the good health of a population. What people want, and what they need are not necessarily the same, nor is the provision of healthcare alone sufficient to guarantee good health. Healthcare demand will almost always exceed the available money to pay for it; and the healthier a population is the more likely that they will spend more money rather than less. Politically and culturally, the main problem for developed countries will be to balance wants and needs, aspiration and economic reality.
Guts and volume for hyperbolic 3-orbifolds with underlying space S3

Abstract Let O be a hyperbolic 3-orbifold with underlying space the 3-sphere. If O contains an essential 2-suborbifold with underlying space the 2-sphere with four cone points, we show how to compute the guts of O split along the 2-suborbifold. When the guts are non-empty, we obtain volume bounds in terms of the topology of the guts. When the guts are empty, we give a complete description of the topological structure of O .
Operando Spectroscopic Microscopy of LiCoO2 Cathodes Outside Standard Operating Potentials

Abstract LiCoO 2 can experience over-lithiation (over-discharge) in an electrochemical cell due to poor battery management, failure such as a short circuit, or when LiCoO 2 is utilized as a negative electrode conversion material. In order to understand the chemical and morphological changes which occur during over-lithiation, LiCoO 2 electrodes were studied during deep discharge to 0.8 V with operando X-ray absorption spectroscopy and spectroscopic X-ray microscopy. During over-lithiation, micron-sized LiCoO 2 particles suffer significant cracking, pulverization and an incomplete conversion to Co metal. These irreversible morphological and structural changes inflict permanent damage on the cathode even during a single over-lithiation event and highlight the need for more sophisticated battery management systems.

Carbon-rich dust from the asymptotic giant branch to planetary nebulae

Abstract As carbon stars evolve from the asymptotic giant branch to planetary nebulae, the spectrum from the dust around them changes from a mixture dominated by amorphous carbon to one dominated by polycyclic aromatic hydrocarbons (PAHs). Along the way, many other components appear, including SiC and MgS, aliphatic hydrocarbons, the still unidentified 21 μm emission feature, and fullerenes. The evidence from infrared spectral surveys suggests that the dust can form with layered structures, that aliphatics can co-exist with the PAHs in post-AGB objects, and that the appearance of the 21 μm feature is associated with aliphatics. Many uncertainties remain. Perhaps the most important is the composition of the amorphous carbon that dominates dust on the AGB, because different compositions can change the total dust output from carbon stars by nearly an order of magnitude.
Sustainable and equitable rights to health: Review of the situation in Sub-Saharan Africa

Background: The perennial increase in global health inequalities necessitates the need for a workable programme besides the traditional trends of health system strengthening. Although, still rudimentary; a sustainable and equitable approach on the rights to health in sub-Saharan Africa is now critical to addressing the burgeoning issue of health inequalities in the region. Of such include, strengthening the capacity of countries in the region to integrate human rights-based approach to health, supporting governments to integrate human rights-based approach in health development and advocacy for health-related human rights. Methods: Via broad criteria the author made the review as inclusive as possible and online search engines and databases including Pubmed, Embase, Google Scholar and Hand searches for studies between 1990-2013 were searched for a period of five months. All database searches were developed iteratively and key words used to generate articles that fit the review topic. Results: The review identified studies that revealed discernible evidence of the need to institutionalize and strengthen human rights approach to the practice of public health and health care delivery in the region. Conclusion: It is essential for all stake holders in the health sector to scale-up the rights to health. This will not only strengthen health care delivery but from a social point of view will facilitate accountability, development of policies and programs consistent with human rights and prevent any form of violations to populations right to health in the region.

A Robust Sign Language Recognition System with Sparsely Labeled Instances Using Wi-Fi Signals

Sign language is important since it permits insight into the deaf culture and allows more opportunities to communicate with those who are deaf or hard of hearing. In this paper, we show that Wi-Fi signals can be used to recognize sign language with sparsely labeled training dataset. The key intuition is that sign language introduces different multi-path distortions in Wi-Fi signals and generates different unique patterns in the time-series of Channel State Information (CSI) values. Based on these observations, we propose a sign language recognition system called WiSign. Different from existing Wi-Fi signal-based human activity recognition systems, WiSign only requires a sparsely labeled training dataset. Two solutions based on transfer learning and semi-supervised learning are proposed to reduce the number of required labeled instances. We implemented WiSign using a TP-Link TL-WR1043ND Wi-Fi router and a Lenovo X100e laptop. The evaluation results show that WiSign can achieve a mean prediction accuracy of 87.01% and 87.38% for the transfer learning-based approach and semi-supervised learning-based approach, respectively.
Mechanisms of phase transformations within the miscibility gap of Fe-rich Fe-Al alloys

Abstract The coherent phase diagram of the Fe-Al system possesses a tricritical point where a line of higher-order transitions ends at a miscibility gap at about 23 at.% Al and 615°C. Rules of general applicability governing phase separation within the miscibility gap of such a system are developed. Application of the rules to the Fe-Al system results in detailed predictions about the mechanisms of decomposition and ordering reactions and their sequences. Electron microscopy is used to study the reactions experimentally and the results are in agreement with theoretical predictions.
Paternal exercise protects mouse offspring from high-fat-diet-induced type 2 diabetes risk by increasing skeletal muscle insulin signaling.

Abstract Paternal obesity increases, while paternal exercise decreases, offspring obesity and type 2 diabetes (T2D) risk; however, no studies have determined whether a paternal high-fat (HF) diet and exercise interact to alter offspring body weight (BW), adiposity and T2D risk. Three-week-old male C57BL/6 mice were fed a normal-fat (NF) diet (16% fat) or an HF diet (45% fat) and assigned to either voluntary wheel running exercise or cage activity for 3 months prior to mating with NF-diet-fed dams. After weaning, male offspring were fed an NF or HF diet for an additional 3 months. F1 male mice whose fathers ate an HF diet had decreased % body fat accompanied by decreased gene expression of beige adipocyte marker FGF21. However, paternal HF-diet-induced reductions in F1 offspring % body fat normalized but did not reduce T2D risk. Exercise was protective against paternal HF-diet-induced insulin resistance by increasing the expression of insulin signaling (GLUT4, IRS1 and PI3K) markers in skeletal muscle resulting in normal T2D risk. When fathers were fed an HF diet and exercised, a postnatal HF diet increased beiging (PPARγ). Thus, these findings show that increases in T2D risk in male offspring when the father consumes an HF diet can be normalized when the father also exercises preconception and that this protection may occur by increases in insulin signaling potential within offspring skeletal muscle. Future studies should further determine the physiological mechanism(s) underlying the beneficial effects of exercise through the paternal lineage.
Electrical Properties of Glass

The purpose of this review paper on the electrical properties of glass is threefold. First, the theoretical basis for understanding the electrical behavior of glass will be reviewed. Second, a synthesis of the understanding of composition and structure effects will be presented; and third, important problems in this area will be discussed. The theoretical review will first consider a general theory of conductivity, followed by more specific discussions of ionic conductivity and electronic conductivity. Dielectric properties of glass will also be considered, including theory, polarization mechanisms, and the current status of understanding composition, thermal history, microstructural and ultra-structural effects. Dielectric breakdown and switching glasses will be briefly considered.
Subregionalism within the OAS

The member states of the Organization differ greatly in terms of size, economic development, social realities and cultural expression. Within this hemispheric diversity there is a natural tendency for countries to polarize into groupings based on a number of factors, of which geographical proximity, economic condition and cultural affinities are important considerations. This tendency has resulted in the development of a wide range of sub-regional groups, each with its own particular agenda, but not necessarily opposed to that of the other. The general complementarity in objectives, modalities of implementation as well as a common operating environment, make collaboration among the various sub-regional groups both logical and desirable.

Neoadjuvant Therapy for Locally Advanced Esophageal Cancer Should Be Targeted to Tumor Histology

Background Controversy exists over the optimal neoadjuvant therapy in patients with locally advanced esophageal cancer (EC). Although most groups favor neoadjuvant chemoradiation (nCRT), some prefer preoperative chemotherapy (nCT) without radiation. The objective of this study was to compare outcomes in EC patients undergoing either regimen, followed by surgery. Methods We reviewed a prospectively collected database of EC patients undergoing esophagectomy after nCT or nCRT from 1989 to 2016. Choice of therapy was at the discretion of the multidisciplinary team. Disease-free survival (DFS) and cancer-specific survival (CSS) were compared by the Kaplan-Meier log-rank test. Independent predictors of CSS were estimated by Cox regression analysis. Results Among 700 EC patients 338 patients were treated with nCRT (n = 112) or nCT (n = 226) followed by surgery. Patients were well matched for age, gender, and clinical stage, although patients with squamous cell carcinoma were more likely to receive nCRT (49% vs 26%, p Conclusions For adenocarcinoma patients undergoing surgery for EC, nCRT leads to increased local tumor response compared with nCT alone but with no difference in survival. For squamous carcinoma patients nCRT appears to improve CSS compared with nCT. For patients with locally advanced EC targeted neoadjuvant regimens should be used depending on tumor histology.
Where are sleeves performed? An analysis of inpatient versus outpatient databases in a large state.

Abstract Background The sleeve gastrectomy (SG) is the most common bariatric surgery in the United States today. There is a trend toward performing SG as an outpatient procedure, either in an ambulatory setting or as an outpatient at a larger hospital. The term “outpatient” is used to designate essentially any patient without an inpatient order. Texas maintains the Texas Inpatient Public Use Data File (IPUDF) database and the Texas Outpatient Public Use Data File (OPUDF) database for inpatient and outpatient settings, respectively. Objectives To determine where SGs are performed by evaluating the Texas IPUDF and OPUDF for 2016. Setting University hospital, United States. Methods The Texas IPUDF and OPUDF were searched with the Current Procedural Terminology code of 43775 and the International Classification of Diseases, 10th revision, procedure code of 0DB64Z3. Patient demographic characteristics were also examined. We looked at the top 5 diagnoses in each database. Results Of the 16,855 SGs performed in Texas in 2016, outpatient SGs accounted for 31.0% (5227 cases), and inpatient SGs accounted for 69% of the total with 11,628 cases reported. For patients reported in the OPUDF, mean length of stay (LOS) was 2.1 (standard deviation 3.2) days with a median of 1.0 (interquartile range = 1, 2) days; for patients in the IPUDF, mean LOS was 1.6 (standard deviation 1.5) days, and the median was 1.0 (interquartile range = 1, 1) days. Conclusion A third of SGs in Texas were performed under outpatient status. Further study is needed to determine the safety of this practice.
Care coordination for chronically ill patients: Identifying coordination activities and interdependencies

Care coordination is important for chronically ill patients who need assistance from a variety of healthcare professionals especially when they transition through different care settings. There has not been a clear definition of care coordination and its associated activities. This paper provides a two-dimension framework of care coordination for chronically ill patients: 1) coordination activities (i.e. communication and monitoring) and 2) interdependencies (i.e. flow, shared resources, simultaneity). We used this framework in a qualitative content analysis of 12 interviews with healthcare professionals involved in coordinating care of chronically ill patients. We identified a total of 258 care coordination activities and developed categories and sub-categories using the constant comparative method. The first category of care coordination activities involves communication with flow or shared resources interdependencies or both. This category includes arranging services and equipment for the patient, exchanging information about patient transition to different care settings, reporting errors and resolving them, and helping the patient with appointments and transportation. The second category involves monitoring, sometimes combined with communication, with flow or shared resources interdependencies or both. This category includes reviewing medications and services and detecting errors, reviewing patient symptoms and following up if needed, and scheduling follow-up to review patient status. The last category involves communication with simultaneity interdependency. This category involves talking in the same location and developing a plan of care, people exchanging information at the same time, and scheduling delivery of medications/services to correspond with patient arrival home. Finally, we identified characteristics of health information technology that can support these various care coordination activities.
Elastomers and Elastoplasts

Rubbers are polymers whose glass transition temperatures lie below the application temperature. Soft rubbers are lightly chemically cross-linked and hard rubbers are strongly chemically cross-linked. Elastoplasts are polymers which are physically cross-linked at the application temperature, but they can be worked like thermoplasts at higher temperatures.
FOUR – APPLICATIONS OF THE DERIVATIVE

Publisher Summary This chapter provides an overview of the applications of the derivative. The derivative can be interpreted as a rate of change. There are many problems involving two or more variables in which it is necessary to calculate the rate of change of one or more of these variables with respect to time. The chapter presents an example of it and suggests a procedure for handling problems of this type. It discusses some steps that are taken to solve a problem involving the rates of change of related variables. The chapter discusses one of the most important and applicable theorems of mathematics—the mean value theorem—that can be used to prove some important facts about differentiation and to obtain information that is useful in graphing a wide variety of functions. The mean value theorem has many other applications as well. The chapter explains elementary curve sketching and considers increasing and decreasing functions and the first derivative test. It also discusses concavity and the second derivative test. The chapter discusses a different kind of application of the derivative considering Newton's method for estimating a solution or root by defining a sequence of numbers that become successively closer and closer to the root sought.
Prognostic significance of translocations in the presence of mutated IGHV and of cytogenetic complexity at diagnosis of chronic lymphocytic leukemia.

Mutations of the IGH variable region in patients with chronic lymphocytic leukemia (CLL) are associated with a favorable prognosis. Cytogenetic complexity (>3 unrelated aberrations) and translocations have been associated with an unfavorable prognosis. While mutational status of IGHV is stable, cytogenetic aberrations frequently evolve. However, the relationships of these features as prognosticators at diagnosis are unknown. We examined the CpG-stimulated metaphase cytogenetic features detected within one year of diagnosis of CLL and correlated these features with outcome and other clinical features including IGHV. Of 329 untreated patients, 53 (16.1%) had a complex karyotype (16.1%), and 85 (25.8%) had a translocation. Median time to first treatment (TFT) was 47 months. In univariable analyses, significant risk factors for shorter TFT (p3.5, log-transformed WBC, unmutated IGHV, complex karyotype, translocation, and FISH for trisomy 8, del(11q) and del(17p). In multivariable analysis, there was significant effect modification of IGHV status on the relationship between translocation and TFT (p=0.002). In IGHV mutated patients, those with a translocation had over 3.5 times higher risk of starting treatment than those without a translocation (p
Three Reversible Redox States of Thiolate-Bridged Dirhodium Complexes without Metal-Metal Bonds.

An unusual dinuclear rhodium complex with the anionic 2-mercapto-6-methylpyridinate (mmp) bridging ligand is reported which is capable of undergoing significant variations in its structural and coordination environments as a result of two reversible redox events at accessible potentials (E1/2 = 0.014, 0.52 V vs Ag/AgCl). The large degree of separation between these redox states (ΔE = 0.51 V, KC = 4.17 × 108) allows for the chemical isolation of three distinct complexes 1, 2, and 3, in which the oxidation states of each Rh center are Rh2I,I, Rh2I,II, and Rh2II,II, respectively, and whose solid-state structures were elucidated by single crystal X-ray diffraction studies. Complex 2 is an unprecedented type of mixed valence dirhodium species whose electron paramagnetic resonance spectrum revealed a delocalization of the unpaired electron through the thiolate-bridging ligand. Intervalence charge transfer occurs between the Rh centers, as evidenced by a broad absorption in the near-infrared region (λmax = 1187 nm). The structure of 3 is quite rare in that it lacks the typical RhII-RhII σ bond, but significant orbital overlap between the Rh 4dz2 and S 3pz orbitals results in a strong antiferromagnetic coupling (computed J = -1516.9 cm-1). Complex 3 also absorbs low-energy light (λmax = 779 nm). Spectroscopic and magnetic measurements are supported by density functional theory methods, which further elucidate the nature of the ground state energies, frontier orbital characters, excited state transitions, and presence of weak Rh-Rh natural bond orbital interactions.
Internal Bremsstrahlung Spectrum Accompanying 1 S Electron Capture in Decay of Fe 55 , Cs 131 , and Tl 204

The internal bremsstrahlung spectra in coincidence with the $K$ x rays resulting from $1S$ electron capture in ${\mathrm{Fe}}^{55}$ and ${\mathrm{Cs}}^{131}$ have been measured. The results are in good agreement with Martin and Glauber's revised calculations including relativistic and screening effects. The shape of the coincidence spectra exhibits a maximum at the predicted energy and then drops off in intensity toward the low-energy region. This is markedly different from that of the total bremsstrahlung spectrum, which rises continuously toward the low-energy region. In the case of ${\mathrm{Cs}}^{131}$, the shape of the bremsstrahlung spectrum pertaining to the radiative capture of $P$ electrons as obtained by subtracting from the total spectrum the spectrum due to $S$-electron capture is also in good accord with that predicted. An estimate of the total probability for bremsstrahlung production during $1S$ electron capture as obtained by comparing the corresponding bremsstrahlung spectrum with the x-ray intensity gives (1.5\ifmmode\pm\else\textpm\fi{}0.8)\ifmmode\times\else\texttimes\fi{}${10}^{\ensuremath{-}5}$ for ${\mathrm{Fe}}^{55}$ and (1.4\ifmmode\pm\else\textpm\fi{}1)\ifmmode\times\else\texttimes\fi{}${10}^{\ensuremath{-}5}$ for ${\mathrm{Cs}}^{131}$, which is in fair agreement with the theoretical prediction including relativistic corrections. The end point of the $1S$ electron capture bremsstrahlung spectrum of ${\mathrm{Tl}}^{204}$ was also measured and found to be 310\ifmmode\pm\else\textpm\fi{}10 kev.
Rare case of symptomatic calcific tendinopathy of the origin of rectus femoris tendon

Although calcific tendinopathy of the shoulder is a relatively common clinical diagnosis, calcific tendinopathy of the rectus femoris tendon near its origin at the anterior inferior iliac spine is rare. We present a case of a 53-year-old female avid runner with left hip pain. Clinical evaluation and X-ray imaging led to a diagnosis of calcific tendinopathy of the rectus femoris tendon. The patient was treated conservatively with non-steroidal anti-inflammatory drugs, physical therapy and rest. Calcific tendinopathy of the rectus femoris tendon can occur rarely in active patients and may be a cause of hip pain, responsive to conservative management, but with other treatment options possible if recalcitrant.
Genotyping on one case with Chikungunya infection introduced into Tianjin in China from Myanmar

Objectives: A clinical case caused by Chikungunya virus (CHIKV) was introduced into Tianjin, China from Myanmar. The current study is aimed to phylogenetically analyzing this imported strain and to reveal the relationship between this virus and other circulating CHIKV strains. Methods: RNA was extracted from serum of the suspected patient presenting with symptoms compatible with CHIKV infections. Real-time reverse transcription PCR (RT-PCR) assay was used for diagnoses of the patient. For phylogenetic analysis, envelope glycoprotein 1 (E1) gene of CHIKV was amplified by two-step RT-PCR and the products were sequenced. Results: The phylogenetic analyses revealed that the imported CHIKV belong to Indian Ocean Lineage (IOL) derived from ECSA genotype and sharing the same cluster with the Aede albopitus-adapted strains that triggered the outbreaks in Pakistan (2016), Italy (2017) and Bangladesh (2017). Conclusion: The imported CHIKV strain has the potential to cause explosive outbreaks in China and this event happened in Tianjin calls for strengthening the monitoring programs on mosquito-borne diseases in China.
How to Manage Sleeve Complications Through Endoscopy: Strictures

Proper understanding of laparoscopic sleeve gastrectomy complications, including sleeve stenosis, remains pivotal for the bariatric surgeon and practicing gastroenterologist. In this chapter, we will highlight the baseline knowledge and the rate of stricture formation after sleeve gastrectomy. Additionally, we review the mechanisms of stricture formation as well as the most common location within the gastric sleeve. Finally, this review provides and in-depth discussion of currently available endoscopic treatments for sleeve stenosis. At present, balloon dilation remains the preferred strategy for treatment of sleeve-associated strictures; however, stenosis length and location may suggest preference for which type of balloon should be utilized. Other endoscopic strategies that are also reviewed include placement of a self-expanding metal stent (SEMS) or more novel techniques such as endoscopic tunneled stricturotomy or gastric peroral endoscopic myotomy (G-POEM). Ultimately, an individualized treatment approach should be undertaken to ensure successful dilation and lasting results.
Brown Envelope Journalism: A panacea to low salaries of Journalists: A case of Tanzania

This book brings out an interesting insight into why Journalists in Africa galvanize Brown Envelope Journalism (BEJ) with good names. The reality is that this notion acts as a remedy to their poor remuneration. It is little wonder that Brown Envelope has now turned into a serious journalism field; a field that is raising questions among Journalism scholars in Africa. Some scholars have called it corruption in the media, very few call it corruption.

A Mini-review of Current Methods and Emerging Technologies in Articular Cartilage Repair

Articular cartilage defects tend to have silent progress, leading to joint incongruency, secondary osteoarthritis, and subsequently pain, restricted mobility, and quality of life impairments in patients worldwide. Yet, functional articular cartilage repair has remained a big challenge in the orthopedics and tissue engineering field. In this mini-review, the clinical efficiency of the currently used methods and procedures for articular cartilage repair and promising emerging technologies that would possibly replace or be implemented in the currently used techniques were highlighted. The future directions in articular cartilage repair methods and materials were also critically addressed by elaborating on current limitations hindering the evolution of the emerging technologies supporting articular cartilage regeneration.
Patterns of Extrapulmonary Metastases in Sarcoma Surveillance

Soft tissue sarcomas (STS) most commonly metastasize to the lungs. Current surveillance guidelines variably recommend abdominal and pelvic imaging, but there is little evidence to support this. We sought to determine the proportion of initial pulmonary versus extrapulmonary metastases, the time to development of each, and factors to identify patients that would benefit from abdominopelvic surveillance. We retrospectively reviewed 382 patients who underwent surgical treatment for STS at a single institution. Of the 33% (126/382) of patients who developed metastases, 72% (90/126) were pulmonary, 22% (28/126) were extrapulmonary, and 6% (8/126) developed both simultaneously. Initial extrapulmonary metastases occurred later (log rank p = 0.049), with median 11 months (IQR, 5 to 19) until pulmonary disease and 22 months (IQR, 6 to 45) until extrapulmonary disease. Pulmonary metastases were more common in patients with high grade tumors (p = 0.0201) and larger tumors (p < 0.0001). Our multivariate analysis did not identify any factors associated with initial extrapulmonary metastases. A substantial minority of initial metastases were extrapulmonary; these occurred later and over a broader time range than initial pulmonary metastases. Moreover, extrapulmonary metastases are more difficult to predict than pulmonary metastases, adding to the challenge of creating targeted surveillance protocols.
Good Roads:- Using machine learning to measure how socio and non-socio-economic factors differently influence traffic accident injury rates

This project is based on analyses of socio-economic factors in conjunction with traditional traffic accident, collision and injury data to analyze if they play a meaningful role in predicting motor vehicle-related injury rates and thus be used to help improve traffic safety. Road and census variables are analyzed for socio economic factors. Factual reasons for accidents and vehicle types are analyzed for non-socio-economic factors. Project is divided in two parts consisting of socio and non-socio factors which includes data exploration, prediction modeling and feature extraction. Total casualties per person is taken as target variable and remaining factors as explanatory variables. For socio economic part, two prediction models are created in which prediction curves are compared to perfect ranking curve. Selected model is then tested on LA and DC datasets followed by feature extraction using XGBoost and random forest. Population density and road length are top reasons for total casualties. Relationship between important features and total casualties is analyzed using OLS regression. For non-socio-economic part, two models are considered, from which random forest has a better normally distributed residual vs fitted curve and hence was selected as the final model. Driver inattention and following too closely are the top causes of vehicular accidents.
Annotation of Spatially Resolved Single-cell Data with STELLAR

Spatial protein and RNA imaging technologies have been gaining rapid attention but current computational methods for annotating cells are based on techniques established for dissociated single-cell technologies and thus do not take spatial organization into account. Here we present STELLAR, a geometric deep learning method that utilizes spatial and molecular cell information to automatically assign cell types from an annotated reference set as well as discover new cell types and cell states. STELLAR transfers annotations across different dissection regions, tissues, and donors and detects higher-order tissue structures with dramatic time savings.
The impact of major on college persistence among freshmen

Using national-level data and a two-step procedure combining least squares regres- sion and logit analysis, this paper examines the impact of majors on college persistence among freshmen. Holding other variables constant, women with business majors and unde- cided majors are less likely to persist than other women. Women with health majors are most likely to persist. Men with education majors and undecided majors are less likely to persist than other men. Men with business majors are slightly more likely to persist than other men. Differences in persistence rates are explained by differences in the relative magnitudes of goal-commitment, subject-interest, social-forces, and self-image effects. Some policy recommendations are provided.
Charged gold leaf in urology. II. Ureterovaginal fistula, stenosing vaginitis, and miscellaneous uses in the female patient.

Abstract This article reports on the use of charged gold leaf in the closure of a urethrovaginal fistula resulting from the excision of a urethral diverticulum, in the functional restoration of a stenosed vagina complicated by labial fusion, and in the excision of urethral caruncles. An improved method of applying this material is described which has permitted its wider application in female urologic procedures. The unique properties of gold leaf accounting for its effectiveness are discussed.
Linking funds to actions for global health emergencies

The failings of the international community's response to the Ebola virus disease outbreak in West Africa underscore the need for new mechanisms for governance and mobilization of resources for timely, coordinated responses to public health threats ( 1 ). Creating a global finance mechanism, ideally tied to existing global health frameworks, is a first step. The World Bank recently announced it would create a Pandemic Emergency Facility (PEF). The next necessary element is a trigger to release those funds to support rapid and effective responses during early phases of a public health event. With the World Health Assembly convening soon, we suggest how the World Health Organization's (WHO's) International Health Regulations (IHR) present such an initiator.
Cloning, sequencing, and expression of the Zymomonas mobilis phosphoglycerate mutase gene (pgm) in Escherichia coli.

Abstract Phosphoglycerate mutase is an essential glycolytic enzyme for Zymomonas mobilis, catalyzing the reversible interconversion of 3-phosphoglycerate and 2-phosphoglycerate. The pgm gene encoding this enzyme was cloned on a 5.2-kbp DNA fragment and expressed in Escherichia coli. Recombinants were identified by using antibodies directed against purified Z. mobilis phosphoglycerate mutase. The pgm gene contains a canonical ribosome-binding site, a biased pattern of codon usage, a long upstream untranslated region, and four promoters which share sequence homology. Interestingly, adhA and a D-specific 2-hydroxyacid dehydrogenase were found on the same DNA fragment and appear to form a cluster of genes which function in central metabolism. The translated sequence for Z. mobilis pgm was in full agreement with the 40 N-terminal amino acid residues determined by protein sequencing. The primary structure of the translated sequence is highly conserved (52 to 60% identity with other phosphoglycerate mutases) and also shares extensive homology with bisphosphoglycerate mutases (51 to 59% identity). Since Southern blots indicated the presence of only a single copy of pgm in the Z. mobilis chromosome, it is likely that the cloned pgm gene functions to provide both activities. Z. mobilis phosphoglycerate mutase is unusual in that it lacks the flexible tail and lysines at the carboxy terminus which are present in the enzyme isolated from all other organisms examined.
Thermal RC-network approach to analyze multichip power packages

Semiconductor packaging and interconnect technologies today focus more and more on system solutions with increased modularity and functionality. As an example, mechanical relay replacement by semiconductor solutions rely on the additional control, diagnostic and communication functions that cannot be provided by power devices alone. For cost, thermal performance and mechanical reliability reasons multi chip solutions with separate control and power functions are required. Associated high integration packaging with a high power density can yield critical temperature states in the sensitive semiconductor devices. Enhanced thermal concepts are needed in order to avoid overheating and provide the necessary package performance. The definition of certain junction to case or junction to ambient thermal resistance values alone does not satisfy these needs. Profound understanding of the heat transfer mechanisms at any steady or transient loading is essential for the development of new assemblies. The temperature rises in all dice have to be known at any combination of electrical loading functions. It is practically impossible to replicate all possible field conditions in a laboratory environment. Thermal RC-networks, representing the heat transfer behavior of a multi chip package, help to overcome that issue. Arbitrary stimulus functions can be applied in order to simulate the time dependent temperature responses. The required network parameters can be identified with transient temperature measurements or even finite element simulations.
