Forecasting is a time series analytic that used to find out upcoming improvement in the next event using past events as a reference. One of the forecasting models that can be used to predict a time series is Kalman Filter method. The modification of the estimation method of Kalman Filter is Ensemble Kalman Filter (EnKF). This research aims to find the result of EnKF algorithm implementation on SARIMA model. To start with, preticipation forecast data is changed in the form of SARIMA model to obtain some SARIMA model candidates. Next, this best model of SARIMA applied to Kalman Filter models. After Kalman Filter models created, forecasting could be done by applying pass rainfall data to the models. It can be used to predict rainfall intensity for next year. The quality of this forecasting can be assessed by looking at MAPE’s value and RMSE’s value. This research shows that enkf method relative can fix sarima method’s model, proved by mape and rmse values which are smaller and indicate a more accurate prediction.

Smiley: A Journey of Love by J. George
Authors: MacLeod Lorisia 
Published: August 2020

George, Joanne. Smiley: A Journey of Love. Fitzhenry & Whiteside, 2017.
Smiley: A Journey of Love is the heartwarming story of a blind dog who becomes a St. John Ambulance Therapy Dog. While the story contains some complex topics that early readers might struggle with such as Alzheimer's or puppy mills, the colourful photography that accompanies the text make it an excellent book to be read with an adult. The photographs of Smiley will help very early readers to invest in Smiley’s story though the text is larger and double spaced so that moderate level readers could use this book to build their reading skills. Given the length and amount of text, this book would be longer than could be covered in one storytime but is broken down by chapters so it could be used for a week of storytimes.
Librarians and educators may find this book useful for starting a discussion around blindness or different ability needs. This book frames Smiley’s blindness and dwarfism simply as things that make Smiley himself and while they might change the way he interacts with the world, this book discusses his abilities in a positive way. There is also a part that discusses Smiley’s friendship with Pearl and Pippi which could be used to teach about being respectful of friends' needs. Overall, this book contains high-level vocabulary and concepts but if read with an adult's support can be the start of some very educational discussions.

In the Sky at Nighttime by L. Deal
Authors: Campbell Sandy 
Published: August 2020

Deal, Laura. In the Sky at Nighttime. Iqaluit, NU: Inhabit Media, 2019.
This illustrated poem shows what a polar village looks like at night and what is in the night sky. In the Arctic, winter nights are long, and it is dark as people go about their daily lives, so many people are familiar with the night sky. Tamara Campeau’s illustrations, each of which fill two facing pages, are in deep blue and purple hues, with the sky prominent in them. The text is overprinted on the artwork. Campeau’s rendering of the village has accurate details. Some of the houses have heating oil tanks outside. Paths to the doors have snow heaped alongside them. Power lines, attached to wooden power poles with insulators and transformers, loop through the village. The yellow light from electric lighting shines out through the windows of the houses. At the beginning of the book Laura Deal describes observable things in the sky: stars, falling snow, northern lights, ravens. Towards the end she becomes more figurative, introducing a mother’s song and dreams swirling in the sky.
The text is a six verse poem, each verse beginning with the phrase “In the sky at night time.” The structure of the poem is reminiscent of Stephen Eaton Hume’s 1992 picture book, Midnight on the Farm, which also uses six verses, each beginning with a repeating phrase, to describe a nighttime world, however the two landscapes are distinct.
Because this is an illustrated poem in the form of a picture book, rather than a picture book with text, some of the words are more difficult than one would expect in books for young children. For example, the dreams are “magical and extraordinary.” As a result, this text, simple as it is, will need some explanation. In the Sky at Nighttime is highly recommended for public libraries and elementary school libraries.

Orientation des productions bovines charolaises en Creuse
Authors: LHERM M. , BEBIN D. , LIENARD G. 
Published: August 2020

Les éleveurs de vaches allaitantes ont de nombreuses possibilités de production à partir de la vente en maigre ou de l’engraissement de leurs animaux. Les choix doivent tenir compte de l’évolution des marchés et des systèmes fourragers possibles dans l’exploitation. En région herbagère, comme la zone charolaise centrale, tous les systèmes de production ne sont pas également adaptés, comme le montre l’analyse comparée de trois échantillons d’éleveurs adhérents à un Groupement de Producteurs du Nord Est de la Creuse, et qui vendent leurs veaux mâles soit en broutards, soit après engraissement en taurillons à l’auge ou en jeunes taureaux de 20 ou 24 mois après une période de pâturage. Les meilleurs revenus sont, jusqu’à présent, obtenus avec cette dernière option qui est bien adaptée aux conditions des exploitations, car elle permet une meilleure utilisation des surfaces en herbe et des potentialités de la race charolaise. Elle est néanmoins exigeante en technicité et elle doit être parfaitement menée aux plans techniques et économiques. Mais l’évolution de la conjoncture qui se dessine permettra-t-elle à l’avenir le maintien dans les zones allaitantes de cette production de jeunes bovins concurrencée par celle d’autres régions ?
Variabilité de la valeur énergétique de la graine de soja traitée pour les volailles
Authors: LESSIRE M. , LECLERCQ B. , CONAN L. 
Published: August 2020

L’utilisation de la graine entière de soja chez les volailles ne peut pas être envisagée sans destruction des facteurs antitrypsiques. Pour ce faire, de nombreux traitements thermomécaniques sont utilisables ; ils ont également l’avantage d’améliorer la digestibilité des lipides de la graine. Tous les traitements technologiques comparés ici (extrusion, jet sploding, toastage, micro-ondisation et granulation) améliorent la valeur énergétique de la graine (+ 3 à + 19 %) ; un des plus efficaces est l’extrusion. L’utilisation métabolique des graines extrudées semble indépendante de l’âge de l’oiseau. A l’inverse, aux doses d’incorporation supérieures à celles pratiquées dans l’industrie (< 10 %), la valeur nutritionnelle des graines de soja extrudées décroît.
Elevage et alimentation du cerf (Cervus Elaphus). 1. Caractéristiques physiologiques, besoins alimentaires et élevage des adultes
Authors: THÉRIEZ M. 
Published: August 2020

L’élevage du cerf pour la production de viande se développe actuellement en France, après l’Ecosse et la Nouvelle-Zélande où les premiers élevages ont été créés il y a une vingtaine d’années. Cette espèce se différencie des ruminants domestiques traditionnels par un certain nombre de points dont en particulier une variation très importante de la capacité d’ingestion avec la saison (elle varie du simple au double entre l’hiver et l’été sous l’effet des variations de la photopériode) et une moindre digestibilité des fourrages grossiers (5 à 7 % de moins que le mouton). Les besoins d’entretien des cerfs sont voisins de ceux des bovins ; s’y ajoutent, chez le mâle, des besoins spécifiques pour la croissance annuelle des bois (énergie et surtout minéraux dont une partie provient d’une déminéralisation du squelette). Les naissances gémellaires sont très rares chez la biche dont la fertilité dépend essentiellement du poids au moment du rut (les biches doivent peser 60 kg ou plus). Le poids des faons à la naissance est voisin de 8-9 kg, il varie avec leur sexe et selon le niveau alimentaire moyen du troupeau. La production laitière des biches varie entre 120 et 200 litres en 100 jours selon la qualité du pâturage. Leur lait est très riche en lipides et en protéines (respectivement 10,3 et 7,6 % au cours du second mois de lactation) soit deux fois plus que le lait de vache.

Abstract
The first pilot test of surfactant-polymer (SP) flood in the world with mixtures of anionic-cationic surfactants (Sa/c) was carried out for a high temperature low permeability sandstone reservoir with high content of clay to demonstrate the potential of this novel technique to improve oil recovery.
Low critical micelle concentrations (CMC) of 2.78×10−6 mol/L, ultralow interfacial tension (IFT) of 10−3 to 10−4 mN/m when surfactant concentrations were above 0.025 wt%, and lower phase microemulsion with high oil solubilization of 22, as well as 55.45 % oil washing rate were obtained by using Sa/c. The adsorption inhibitor (AI) was adopted to reduce the adsorption because of the high clay contained in the natural core. Dynamic adsorption was about 0.30 mg/g with addition of AI, as well as IFT kept almost unchanged before and after adsorption.
In order to reduce the injection pressure and improve the mobility ratio in the low permeability reservoir, low molecular weight polyacrylamide was adopted. The viscosity of polymer and SP were 2.96 mPa·s and 4.05 mPa·s, respectively. Core flooding results showed more than 16 % original-oil-in-place (OOIP) crude oil was recovered by SP over water flood.
Since August 2012, the pilot test of SP containing Sa/c was carried out in a Sinopec reservoir with temperature of 83 °C, salinity of 15,000 mg/L, permeability of 41.5 mD, clay of 12 %. Totally 0.40 PV chemicals, including 0.1 PV polymer pre-slug, 0.25 PV SP main slug and 0.05 PV polymer drive, were injected from August 2012 to December 2017 with an injection rate of 0.08 PV/a. After that water drive was conducted. Maximal water cut decreased from 82.2 % to 62.1 %, and the peak daily oil production increased from 12.2 t to 32.3 t. The oil recovery was increased by 8.0 % OOIP by the end of December 2018.
Ethanolamine as Alkali for Alkali Surfactant Polymer Flooding - Development of a Low-Complexity Field Implementation Concept

Abstract
A successful pilot in the Marmul field in the south of the Sultanate of Oman used a formulation consisting of 2% sodium carbonate, 0.3% surfactant, and 0.27% polymer. Marmul crude oil has a high total acid number (TAN = 0.9 mg KOH/ml). The petroleum acids are neutralized by alkali to form soaps which mix with the added surfactant to generate low interfacial tension (IFT) between oil and brine. For a commercial scale chemical-flood the quantity of sodium carbonate that needs to be transported is very large. It has been found that ethanolamine has significant advantages as an alkali for ASP and can substantially improve the logistical challenges faced in implementing a commercial scale flood. Ethanolamine has an improved alkaline density, is a low viscosity liquid, and can function as a solvent for EOR surfactants in the free acid form enabling shipment of a ready to mix liquid AS formulation.
‘Motivational work’: a qualitative study of preventive health dialogues in general practice
Authors: Broholm-Jørgensen Marie , Langkilde Siff Monrad , Tjørnhøj-Thomsen Tine , Pedersen Pia Vivian 
Published: August 2020

Abstract
Background: The aim of this article is to explore preventive health dialogues in general practice in the context of a pilot study of a Danish primary preventive intervention ‘TOF’ (a Danish acronym for ‘Early Detection and Prevention’) carried out in 2016. The intervention consisted of 1) a stratification of patients into one of four groups, 2) a digital support system for both general practitioners and patients, 3) an individual digital health profile for each patient, and 4) targeted preventive services in either general practice or a municipal health center.Methods: The empirical material in this study was obtained through 10 observations of preventive health dialogues conducted in general practices and 18 semi-structured interviews with patients and general practitioners. We used the concept of ‘motivational work’ as an analytical lens for understanding preventive health dialogues in general practice from the perspectives of both general practitioners and patients.Results: While the health dialogues in TOF sought to reveal patients’ motivations, understandings, and priorities related to health behavior, we find that the dialogues were treatment-oriented and structured around biomedical facts, numeric standards, and risk factor guidance. Overall, we find that numeric standards and quantification of motivation lessens the dialogue and interaction between GP and patient and that contextual factors relating to the intervention framework, such as a digital support system, the general practitioners’ perceptions of their professional position as well as the patients’ understanding of prevention —in an interplay—diminished the motivational work carried out in the health dialogues.Conclusion: The findings show that the influence of different kinds of context adds to the complexity of prevention in the clinical encounter which help to explain why motivational work is difficult in general practice.

Published: August 2020

Abstract
Background: Burden of Malaria in pregnancy (MIP) is still high despite availability of proven cost-effective interventions. Considerable progress has been made on improving antenatal attendance but MIP preventive services utilization remains low. Factors responsible for this include dissatisfaction with the services provided. We assessed clients’ satisfaction with preventative services for malaria during pregnancy delivered at antenatal clinics (ANC) in Anambra State Nigeria.Method: We conducted a cross-sectional study among 284 pregnant women attending ANC using a three-stage sampling technique. Pre-tested semi-structured interviewer-administered questionnaire was used to collect information on socio-demographics, knowledge of malaria in pregnancy services and satisfaction with services. Responses to questions on satisfaction was on a 5-point Likert scale. A cut off of ≥75% of composite score was used to classify respondents as satisfied. For knowledge, every correct answer was scored 1 and incorrect 0; ≥75% of the composite score was graded as good knowledge. Chi square and logistic regression were used to test for association between client satisfaction and independent variables.Results: The mean age of participants is 28 years±4.4 years. Overall 62.2% were satisfied with quality of preventive services for malaria during pregnancy. However, 64.8% and 57.8% were dissatisfied with cost of healthcare and interpersonal relationship with the health workers (HWs). Majority of the of respondents (88.73%) had poor knowledge of malaria preventive services during pregnancy. Type of facility (Adjusted odds ratio [aOR] = 2.11; 95%CI: 1.20-3.71) and knowledge (aOR: 0.41; 95%CI: 0.18 – 0.90) were independently associated with satisfaction with interpersonal relationship respectively. Type of facility (aOR: 0.47; 95%CI: 0.27-0.80) and employment status (aOR: 3.07; 95%CI: 1.39 -6.74) were also independently associated with satisfaction with cost of healthcare.Conclusion: A fair proportion of respondents were satisfied with the preventive services for malaria during pregnancy provided even though most were dissatisfied with the cost of assessing care and interpersonal relationship with health workers. Uninterrupted availability of LLIN and IPT at all health facilities, subsidized cost of malaria-related commodities, and incentives for good customer satisfaction ratings may remediate the described barriers to seeking preventative care for malaria during pregnancy.
CA724 predicts overall survival in locally advanced gastric cancer patients with neoadjuvant chemotherapy
Authors: Tong Yilin , Zhao Yan , Shan Zexing , Zhang Jianjun 
Published: August 2020

Abstract
Background: Serum tumor markers including AFU, AFP, CEA, CA199, CA125 and CA724, are of great importance in the diagnosis, prognostic prediction and recurrence monitoring of gastrointestinal malignancies. However, their significance in gastric cancer (GC) patients with neoadjuvant therapy (NCT) is still uncertain. The aim of this study was to evaluate the predictive value of these six tumor markers in locally advanced GC patients who underwent NCT and curative surgery. Methods: In total, 290 locally advanced GC patients who underwent NCT and D2 radical gastrectomy were retrospectively analyzed. Data on their tumor markers before (pre-) and after (post-) NCT and pathological characteristics were extracted from the database of our hospital. The optimal cutoff values of the six tumor markers were calculated by the ROC curve and Youden index. Their predictive significance was analyzed and survival curves for overall survival (OS) were obtained by the Kaplan-Meier method. Associations between categorical variables were explored by the chi-square test or Fisher's exact test. Multivariate analyses were performed by the Cox regression model. Results: Pre- and post-CA199, -CA125 and -CA724 could predict overall survival (all P < 0.05), but only the change (diff-) of CA199 was related to prognosis (P = 0.05). In the multivariable analysis, pre- (P = 0.014) and post-CA724 (P = 0.036) remained significant, though diff-CA724 was not an independent prognostic factor (P = 0.581). In addition, pre- and post-CA199, -CA125 and -CA724 were associated with lymph node metastasis (N- vs N+) and pathological stage (Ⅰ-Ⅱ vs Ⅲ) (all P < 0.05). Moreover, post-CA724 was related to the vascular or lymphatic invasion (P = 0.019), while pre-CA724 was not (P = 0.082). However, AFU, AFP and CEA showed no association with survival (P > 0.05). Conclusions: CA724 is an independent factor for prognosis and could be used to predict ypN and ypTNM stage in locally advanced GC patients undergoing NCT and curative resection.

Published: August 2020

Abstract
Background: Public-private partnership in the health sector was introduced to improve the delivery of health services in Tanzania. Contrary, the expected outcomes have not been fully realised. This study aimed at investigating challenges encountered in implementing public-private partnership institutional arrangements in health service delivery in Kinondoni Municipality, Dar es Salaam, Tanzania.Methods: A qualitative case study design was employed, where in-depth interviews with stakeholders were held and document reviews conducted. Fourteen (n=14) participants engaged in this study. Eight (n=8) and six (n=6) of the fourteen participants were from the public and private sector, respectively. The thematic approach was used to analyse data, and ethical principles in the research process were upheld.Results: Findings revealed that although public-private partnerships are hailed for supplementing the government’s efforts in the provision of health services, institutional arrangements for the smooth provision of these services are lacking. Several challenges encumber smooth provision of health services and these include inadequate resources, ineffective monitoring and evaluation, and insufficient consultations between partners.Conclusion: Inadequate legal and policy framework, or ineffective implementation practices may influence challenges facing institutional arrangements for public-private partnerships. Therefore, strengthening of public-private partnerships is recommended to improve implementation mechanisms and practices such as adherence to partnership agreements and compliance to the policies, laws and regulations.
Effect of Resilience on Infertile Couples’ Quality of Life: An Actor–Partner Interdependence Model Approach
Authors: Ha Ju-Young , Ban Seonhwa 
Published: August 2020

Abstract
Background Infertility is an emerging socioeconomic issue affecting an individual’s life and the nation. However, only few studies have examined the influence of resilience on the quality of life (QoL) of spouses as actors and partners. Hence, this study aimed to analyze the influence of resilience, a positive factor that infertile couples may have, on QoL using the actor–partner interdependence model (APIM).Methods By the analyses of couples’ data, we analyzed the effect of resilience on the QoL of infertile couples as actors and partners. This cross-sectional study included 150 infertile couples. The Fertility Quality of Life and Resilience Scale was used to measure couples’ QoL and resilience. APIM was applied to analyze QoL.Results In terms of actor effects, the resilience of both wives (β = 0.201, p < 0.001) and husbands (β = 0.713, p < 0.001) had a significant effect on individual QoL. With regard to partner effects, husbands’ resilience (β = 0.351, p < 0.001) had a significant impact on wives’ QoL and the wives’ resilience (β = 0.219, p = 0.009) had a significant impact on husbands’ QoL.Conclusions The resilience of an infertile actor was found to affect both his/her own QoL and his/her partner’s QoL. In the future, if a program is to be developed to improve couples’ QoL, both spouses should work together to improve their resilience, thereby improving their QoL.
