The Ancillary Response of Storage Power Plants (SPP) in the Present and Future Electrical Grid

It is expected that in the near future, the electrical power supply networks will be significantly revolutionized. Most of today’s conventional power plant structures will give way to a novel, inertia independent (free from rotating masses) power plant system. Such systems, called storage power plants, will possess storages for different generation speed together with power electronic converters. They will be able to integrate and store energy from renewable sources. However, to be deemed truly feasible in the present scenario, these storage power plants must be able to function efficiently when they are integrated with conventional power plants and renewable energy sources. They should be able to satisfy the frequency dependent grid regulatory services involving spinning reserve, primary and secondary control in combination with other types of power plants. Hence, in this paper, the storage power plants are connected with thermal, hydroelectric and wind power plants, in a single network, and their dynamic ancillary response is studied when there are sudden disturbances in the electrical grid in the form of changes in power consumption by loads or generation from renewable sources.
INVESTMENT EFFICIENCY DURING THE EARLY YEARS OF A CEO’S TENURE

Career concerns are escalated during the early years of a CEO’s tenure because the market is uncertainty about the new CEO’s ability and the compatibility between his or her skills and the firm’s strategic needs. This study examines whether such increased career concerns induce investment inefficiency during the early years of a CEO’s tenure. I find that underinvestment is more likely to happen in the early years than in the later years, and that the underinvestment problem is most evident when the CEO is externally appointed, holds an interim position, and has low managerial ability, and when the firm has a higher level of information asymmetry and lower financial reporting quality. I also find that firms are less likely to issue debts during those early years, which suggests that a reduced supply of capital can contribute to the underinvestment phenomenon in the early years of a CEO’s tenure. Together, these findings indicate that during the early years of a CEO’s service, especially in contexts where career concerns are high and the information environment is more asymmetric, investment inefficiency is more likely to occur.
Outbreak of Human Streptococus suis Cases in Chum Phuang District, Nakhon Ratchasima Province, Thailand, 2018

Streptococcus suis (S. suis) is a major public health problem in northeastern Thailand. On 17 Apr 2018, the Office of Disease Prevention and Control 9 received a notification of five patients with S. suis infection in Chum Phuang District, Nakhon Ratchasima Province. We investigated to confirm the etiology, describe the epidemiological characteristics, and identify the source of this outbreak. Medical records and laboratory results at the district and provincial Hospitals were reviewed. We interviewed family members and people who shared meals with cases. We surveyed slaughter processes at two implicated slaughterhouses. Surveillance for S. suis cases was also enhanced. Six confirmed cases of S. suis serotype 2 infection were found in six sub-districts of Chum Phuang District between 1 Jan and20 Apr 2018. Clinical presentations of confirmed cases were fever (100%), headache (50%) and hearing loss (50%). Five of the six cases ate raw pork with an average incubation period of 2.3 days. Those who ate raw pork were more likely to get infected (RR = 13.5, 95% CI = 1.7-105.1). One from 27 specimens identified S. suisserotype7 from a slaughterhouse in Chum Phuang District. The outbreak continued with an additional 14 confirmed cases in province during the monitoring period from 20 Apr to 25 Jul 2018. Increasing health awareness of the public and physicians beyond ensuring proper management in slaughterhouses should be strengthened.
CAUSAL RETURNS TO POSTSECONDARY EDUCATION IN CHILE: FIELDS, SELECTIVITY, STUDENTS AND LUCK

We use new administrative data from Chile from 1985 through 2010 to estimate the causal returns to a college degree as a function of field of study, course requirements, selectivity, measures of school quality, and student socio-economic status. It is to our knowledge the first study to examine the causal impact of these factors on short and long-run labor market outcomes. Our data link high school records to entrance exam records to college applications, admission, matriculation, and finally labor market earnings from tax records. Because the Chilean admission system for most universities is centralized and test-score based, we are able to exploit hundreds of regression discontinuities to estimate the causal impacts of interest. We use the reduced-form estimates to estimate a simple wage model, which allows us to compare the earnings effects of each program to a common outside option. We find that returns are highly heterogeneous by field of study, with particularly large returns in health, technology and business. Earnings gains are larger for more selective programs, with little to no gains from admission to lowselectivity degrees or degrees with vocational curriculum focus. Heterogeneity in gains are not fully captured by differences in tuition across institutions and degrees. We do not find differential outcomes for students coming from low versus high SES backgrounds. Our results support the claim that persistent frictions exist in supply of institution-degrees relative to demand for skills, or in demand response to returns through informed student choice. Both suggest a role for public policy in decreasing frictions. *We thank Phillip Ross and Unika Shrestha for outstanding research assistance.

Air Pollution In Mid-20Th Century United States: Effects On Infant Mortality And Property Values

This paper studies the local impact of air pollution on infant mortality and housing prices. The empirical analysis relies on the historical expansion in fossil fuel electricity generation from 1938 to 1962, the leading source of domestic coal consumption by the mid-20th century. Combining newly digitized information on plant-level coal consumption with county-level air quality measures and infant mortality rates, we find that increases in coal consumption are associated with higher concentrations of total suspended particulates (TSPs) and increases in infant mortality. Our estimates suggest that the rise in power plant emissions was responsible for an additional 9,486 infant deaths over the sample period. We examine whether these health costs were capitalizated into housing values. Although estimates of the average marginal willingness to pay for clean air are close to zero, there appears to be significant heterogeneity in the housing market response. At low levels of baseline electricity access, thermal power plants are considered an amenity by local residents. As access to electricity expands, the pollution costs overwhelm the benefits of energy production, and the relationship between thermal emissions and housing prices reverses. These results highlight a challenge for current energy policy in the developing world: Given the longevity of electricity generation infrastructure, policymakers must take into account both current and future preferences for thermal power when making investment decisions. ∗Karen Clay: Mailing address: Carnegie Mellon University, 5000 Forbes Ave., Pittsburgh, PA 15213, Phone: (412) 268-4197, Email: kclay@andrew.cmu. edu Joshua Lewis: Mailing address: Université de Montréal, 3150, rue Jean-Brillant, Montréal, QC, H3T 1N8, Phone: (514) 240-4972, Email: joshua.lewis@umontreal.ca.

Recommendation Algorithm Based on Dual Attention Mechanism and Explicit Feedback

The recommendation algorithms are popular in intelligent applications, and the algorithms seamless integration with the knowledge graph has attracted much attention in recent years. However, the existing methods can not make full use of auxiliary information in KG and characterize user-item interaction behavior violence which lead to the recommendation algorithms are still limited by sparse or even cold start issue, and the recommendation results are weakly interpretable. To address the problem, this paper proposes an enhanced CTR recommendation algorithm based on knowledge graph dual attention mechanism and user explicit feedback. Here,(1) The dual attention mechanism is for KG, which can be divided into inter-item attention mechanism and inter-layer attention mechanism. The inter-item attention mechanism calculates the correlation between the item clicked by the user and the entity connected to the item in the KG. Meanwhile, the inter-layer attention mechanism calculates the correlation between different hops in the KG. (2) The user explicit feedback is the user’s degree of preference for the item expressed in numerical form and is used to quantify user-item interaction behavior. Finally, in order to evaluate the usability of our proposed method, three datasets with different sparsity, another three datasets which rich in new items, and a new evaluation task-interpretive visualization were designed to conduct multi-view experimental verification.
Investigation on Lipid Profile in Affective Disorder at a Hospital Clinic in Kolkata, West Bengal, India

Ab s t r Ac t Aim: Prior research has shown that particular types of mental states contribute to one’s risk for depression, and that abnormal blood lipid levels can be associated with the manifestation of mood dysfunction. The role of lipid metabolism in the pathophysiology of depressive behavior has received particular attention recently. As depressive disorders vary in regard to etiology and diagnostic marker, the present study aimed to explore any lipid-profile disparity among the sample of depressive patient groups visiting a clinic for treatment. Materials and methods: The study group consisted of 80 patients diagnosed with three types of depressive disorders—endogenous, reactive, and dysthymic types. Groups were tried to match according to age, gender, and education. Results: The demographical difference between marital status and economic status revealed among patients. The present study reveals the difference among serum lipid levels among groups in regard to LDL cholesterol (lipoproteins of low-density). Further after adjusting the confounding factors such as age and BMI, the ratio of HDL (lipoproteins of high-density)/cholesterol and also the ratio of LDL/HDL were found to be significantly different among the groups. Conclusion: The present study shows the difference in lipid profile such as LDL cholesterol, HDL/cholesterol, and HDL/LDL ratios among psychogenic, reactive, and dysthymic groups. The psychogenic group reflects lower LDL and lower LDL/cholesterol, HDL/cholesterol ratios while compared to others. Clinical significance: This study highlights how the lipid profile can act as a biological marker in distinguishing depression subgroups and assessing associated cardiovascular risks.
Capturing Eviction in America: Forced Dislocation and the Iconography of the Housing Crisis

Since the subprime mortgage crisis caused the inflated housing bubble to burst in the United States in 2007, increased housing insecurity and the prospect of eviction are no longer experiences associated with the urban poor. The 2007-2008 housing crisis in fact demonstrates how residential homes have transformed from asset to liability for the middle class as well. Subsequently, the downward mobility middle class evictees undergo poses the question of how a supposedly stable concept of the middle class becomes mobilized and shifts its meaning. This essay explores how the increasingly pervasive genre of ‘eviction photography’ deals with such mobilizations in the current class structure. Informed by narrative theory as well as cultural geography, it shows how images of forced dislocation both locate the housing crisis in concrete spaces and chart its affective implications. Theories on spatial inequality and the political imagination of art by Ariella Azoulay, Walter Benn Michaels, and Jacques Ranciere, amongst others, provide the framework for my inquiries. I draw on selected photographs that attest to the aftermath of foreclosure as a foil to John Moore’s World Press Photo award-winning series Evicted , which stands out for the distinct attention it pays to the human subjects involved in the process of eviction. In the imaginary nexus between photographer, photographed, and spectator, Moore’s images are read as visual and spatial interventions that construct intimate yet shared knowledge about contemporary social and economic inequalities.
The Association Structures and Sustainability of Methyl Red and Methylene Blue In Water Systems, A Nonionic Surfactants (Tween-40 And Tween-80) And Cyclohexane

Surfactants mixed with water and oil will form associative structures such as microemulsions and liquid crystals. Microemulsion and liquid crystals can dissolve dyes. Dyestuff solubility is widely used in various industrial fields, for example in paints, textiles, cosmetics and inks. This study aimed to determine the association structure and the solubility of methyl red and methylene blue in the water system, the nonionic surfactant (Tween-40 and Tween-80) and cyclohexane. In this study, 2 association structures have been formed in the water system / Tween-40 / cyclohexane and 3 association structures in the water system / Tween-80 / cyclohexane. Determination of the association structure is done through visual observation and using parafilm at various points (± 200) in the phase diagram. Methyl red dyes are dissolved in microemulsions and liquid crystals in acidic pH while methylene blue is in alkaline pH so that a stable color is obtained. The average solubility of methyl red in microemulsion of 0.0032 g in 1 gram of the sample and the average solubility of methyl red in the liquid crystals is 0.0033 grams in 1 gram of sample. As for the average solubility of methylene blue in the microemulsion is 0.0013 grams in 1 gram of the sample and the average solubility of methylene blue in the liquid crystal by 0.0014 g in 1 gram of sample. The measurement of the refractive index in some samples showed methyl red and methylene blue dissolved homogeneously in the sample. The refractive index value of the sample after dissolving the dye is higher than the refractive index value before the dyestuff is dissolved, because the dye changes the composition of the sample. The viscosity of the microemulsion before the dyestuff is dissolved is lower than the viscosity that has been dissolved by the dyestuff.
Drug-induced renal disorder-A Mini Review

Drug-induced kidney disorder/disease (DKID) is an origin of kidney disease followed by acute renal failure. Drug-induced renal toxicity is more common in infants and young children in certain clinical circumstances where underlying renal dysfunction and cardiovascular diseases. Sometimes, administered drugs may cause acute renal injury, intra-renal obstruction, interstitial nephritis, nephrotic syndrome, and acid-base and fluid electrolytes disorders in patients. Certain drugs may cause alterations in intra-glomerular hemodynamics, inflammatory changes in renal tubular cells, leading to acute kidney injury (AKI), interstitial tubule disease, and renal scarring. Common risk factors include; pre-existing renal dysfunction, volume-depleted state, old age, and use of nephrotoxic drugs. Therefore, the prevention from the disease includes the knowledge about the nephrotoxicity, assessing considering the patient-related, kidney-related, and drug-related factors while prescribing medicines, using of alternative drugs, which are non-nephrotoxic, assessing the baseline of renal function before starting the treatment, monitor the renal function during the treatment and avoid the nephrotoxic drug combinations and withdrawing the offending drugs due to toxicity. The ADRs of the prescribed/ administered are identified at the earliest to prevent the development of the last-stage renal disorder. This review discusses the risk factors associated with drug-induced renal disease, estimation of renal function, mechanism of drug-induced nephrotoxicity, and certain drugs that cause nephrotoxicity.

The spontaneous fermentation was carried out on Carica papaya leaf (CPL) in view of its potential improvement on antioxidant functionality and cultivation of lactic acid bacteria. The effect of the spontaneous fermentation on the total phenolic content and antioxidant activity of CPL, as well as biodiversity profiling were evaluated in this study. Total phenolic content and antioxidant capacity of the fermented CPL were 31.14 mg GAE g-1 and 405.8 mM TE g-1 respectively, higher than the unfermented CPL (5.71 mg GAE/g and 130.5 mM TE g-1) respectively. Microbial community was predominantly lactic acid bacteria (LAB) and yeasts, both populated at 104 to 108 CFU/mL during most part of the fermentation. Presumptive Enterobacteriaceae showed up briefly at the onset of the fermentation before disappearing. PCR-DGGE fingerprinting revealed Lactobacillus plantarum (Lb. plantarum) as the sole dominant bacterial species. More diverse yeasts community was detected by PCR-DGGE where succession of Zygosaccharomyces, Saccharomyces, Candida and Aspergillus genera were detected along fermentation time. Spontaneous fermentation successfully enhanced the total phenolic content and antioxidant capacity of the CPL. The cultivation of lactic acid bacteria was indicated by the presence of Lb. plantarum, whereas the disappearance of Enterobacteriaceae conferred a safe consumption of the fermented CPL.
INFLUENCE OF A TRAILING EDGE FLAP ON A VERTICAL AXIS WIND TURBINE PERFORMANCE

The present research was carried out to summarize t he ffect of an attached flap at the trailing edge on a vertical axis wind turbine performance. Two mo dels were tested in a wide range of initial flow velocity and blade pitch angles. The first mod el has two blades, and in the second model four blades were used. The pitch angle was varied from 1 5 to 60. The torque and power coefficients were measured. A comparison with data obtained with the model without flaps is given. It is found that the torque and power coefficients increase wit h increasing the pitch angle up to 45 o and then decrease at the a higher value of the pitch angle. Th attached flap reduces the flow separation, enhances lift, captures more wind energy, increases the rotor speed and hence increases the torque and power coefficients. The flap at a position L/C f= 0.75 for the rotor has a pitch angle of 45 o gives an optimum value of the power and torque coef fici nts compared to the other values of L/C f . At these conditions, an improvement of 7.14 % is achieved (for the rotor has two blades), and of 12.7 % (for the rotor has four blades) compared to the rotor without flaps. د نع ا ھل ي فلخلا ءزجلا دنع شيرلل دادتما عضو ريثأتو روحملا ةيسأر ةيئاوھ ةنيبروت ءاد" ةيلمع ةسارد ثحبلا مدقي اھئادأ لدعم ىلع ةفلتخم عضاوم . عبرأ تاذ ىرخ"او شيرلا ةيئانث ىلو"ا تانيبروتلا نم نيعون ىلع ةساردلا تمت ارد ع م ةرد قلاو مز علا ل ماعم سا يقب ك لذو شير لا ن م ن م ةش يرلا ع ضو ة يواز ر يغت ريثأ ت ة س 15 ° ى لإ 60 ° دادتم5ا ءزج دوجو مدع يف اھتليثم عم جئاتنلا تنروقو . ةدا يزب ةرد قلاو مز علا لماعم نم 9ك ةدايز جئاتنلا ترھظأ ةيواز ىتح ةشيرلا عضو ةيواز 45 ° ض فخ ى لإ ىدأ دادتم5ا حطس نأو ربك"ا اياوزلا عم ميقلا هذھ تلق كلذ دعبو ةرد قلاو مز علا ةدا يز ى لإ ىدا ا مم نارود لا ةعر س ةدا يز ى لإ ىدا ع فرلا لماعم مظعو نايرسلا لاصفنا ، ع ضو نا ى لع شيرلا 45 ° ة ميق د نع داد تم5ا ءز ج ا ھعمو 0.75 مز علا ن م ءادأ لد عم ى لعأ ت طعأ ث يح ى لثملا مي قلا ي ھ ةرد قلاو . ى لإ ل صو ةرد قلا ل ماعم ةدا يز ةبس ن نأو 7.14 % ة لاح ي ف ت ناكو شير لا يئا نث نيبرو تلا 12.7 % دادتم5ا ءزج نودب نيبروتلل ةنراقم شيرلا يعابر نيبروتلل .
Agricultural Liming in Zambia: Potential Effects on Welfare

Soil acidity is crucial for crop yields. Acidic soils decrease the availability of important nutrients to plants, causing lower yields. This applies to both naturally occurring nutrients and fertilizer. A well-known remedy is to provide soils with alkaline materials, like ground limestone. This raises their pH levels, increasing the availability of nutrients to the plant and eventually crop yields. So far, this practice is not widespread in Zambia, a country with largely acidic soils in agricultural areas. The agriculture of Zambia is dominated by smallholder farmers, growing predominantly maize. This paper seeks to quantify the effects on welfare that the introduction of liming would have in the Zambian smallholder maize market. For this purpose, I develop a dynamic, deterministic, open market, spatial partial equilibrium model. Solving the model requires bounded, monotonic, non-convex mixed-integer optimizations with equilibrium constraints. Model results indicate that liming in this market would reduce prices by 22.8% and increase welfare by 3.4% without international trade. With exports at 350 USD/t, the local price would drop by 16.1% and welfare would increase by 5.6% due to liming.
EVALUATION OF FLOOR VS. CAGE SYSTEM OF BROILER CHICKENS REARED IN THREE DIFFERENT AREAS OF ENCLOSED HOUSES ON PRODUCTIVE AND PHYSIOLOGICAL PERFORMANCE

This study was conducted to evaluate the effects of two housing systems cage vs. floor on productive performance and physiological response of broiler chickens reared in three rearing areas in enclosed houses including side cooling (vent area) , middle and at the end of the house (fan area). A total number of 3120 chicks were randomly chosen for both housing systems, where enclosed houses of cage battery and floor systems having 83200 and 22500 birds respectively.The number of 3120 chicks were divided into two groups: the first was housed in cages (n=1560) and the second was housed on the floor house (n=1560). Birds were placed in three different rearing areas containing 520 birds each. Each area per housing system was replicated four times containing 130 birds each. Results showed that LBW, BWG, FI, FCR, livability and EPEF recorded significantly (P ≤0.05) higher values for birds housed in cages than birds housed on floor. However, the former traits showed better (P ≤0.05) results for birds placed in vent area than birds placed in middle and fan area. Housing systems or rearing areas significantly (P ≤0.05) affected total faecal microbial count, where the birds housed on floor and placed in fan area exhibited (P ≤0.05) higher values than birds housed in cages and placed in middle and vent areas. Antibody titer response detected against NDV for birds placed in vent and middle areas showed higher values than birds placed in fan area. It may be concluded that, rearing broiler chickens in cage system and placed in vent area were better in obtaining the highest productivity and physiological response compared with those reared on floor system and placed in middle and fan areas.
Clinical Studies Reported in the 75th Annual Scientific Sessions of the American Heart Association (Chicago, November 17-20, 2002)

Rev Esp Cardiol 2003;56(1):89-98 89 In the 75th Congress of the American Heart Association, the results of some clinical trials selected for their special importance were presented in special sessions (late breaking clinical trials). The majority of these studies have not yet been published, so the results reported here should be considered preliminary. Below we summarize the background, objectives, methods, and results of these studies.
