Abstract. Information and data on newer drought-tolerant maize hybrid response to water in different climates are extremely scarce. This research quantified the performance of non-drought-tolerant (NDT) (H1) and drought-tolerant (DT) (H2, H3, and H4) maize ( L.) hybrids response to grain yield, crop evapotranspiration (ETc), basal evapotranspiration (ETb), ETc-yield production functions (ETYPF), and crop water use efficiency (CWUE) at three irrigation levels and two plant population densities (PPDs) at two locations (transition zone between sub-humid and semi-arid climates at Clay Center (SCAL), Nebraska, in 2010 and 2012; and in a sub-humid climate at Concord (HAL), Nebraska, in 2010, 2011, and 2012). Irrigation treatments were: fully irrigated (FIT), early cutoff (ECOT) (i.e., no irrigation after blister stage), and rainfed (RFT) under two PPDs of 59,300 plants ha-1 (low PPD), and 84,000 plants ha-1 (high PPD). Generally, DT hybrids performed superior to NDT hybrid consistently at both locations, treatments, and years. DT H3 and DT H4 had highest grain yield consistently at SCAL and HAL, respectively. DT H3 and H4 hybrids’ productivity was not only superior in the RFT, but also in FIT. The highest yield of 16.3, and 15.3 Mg ha-1 were achieved by DT H3 (high PPD) and DT H2 (high PPD), respectively, associated with 471 and 590 mm of ETc in the FIT in 2012 at SCAL, and HAL, respectively. In most cases, all hybrids had highest grain yield under low PPD than high PPD at the RFT. All hybrids exhibited a linear yield response to increasing ETc in all years at both locations with positive slopes in all cases. The individual ETYPF response for individual hybrids had inter-annual variation in slopes between the hybrids and for the same hybrids between the years and location for both low and high PPDs. The ETYPF slopes ranged from 0.004 to 0.102 Mg ha-1 mm-,1 including all treatments (i.e., irrigation and PPDs) at SCAL for 2010 and 2012; and they ranged from 0.008 to 0.057 Mg ha-1 mm-1 including all treatments at HAL for 2010, 2011, and 2012. The ETb values exhibited inter-annual variation for the same hybrid between the irrigation levels, PPDs, and locations and they also exhibited an inner-annual variation between the hybrids and treatments in a given year with DT hybrids having consistently lower ETb values than the NDT hybrid. The greatest CWUE values were found in DT hybrids consistently at both locations. The DT hybrids can significantly increase yield productivity as well as crop water productivity per unit of ETc with respect to conventional hybrids not only in dry conditions, but also in average or above average years in terms of precipitation.

Published: March 2019

Abstract.We present a crop plan that aims to maximize farmers’ returns and minimize production costs for the analyzed agricultural holding. This study describes a model that combines linear programming (LP) and the weighted goal programming (WGP) method with penalty functions to simultaneously satisfy a variety of goals within the tolerance interval bounds in terms of their weights. The results indicate that, from an economic perspective, WGP sub-model including LP gives a better solution than using the LP sub-model separately. We designed the model to handle five different types of field and vegetable crops during crop planning and was tested for WGP optimization [WGPSC1, WGPSC2, WGPSC3, and WGPSC4 (SC4 for testing model parameterization)) on four different scenarios. For example, the farmers’ returns in the WGP scenarios were higher or equal as in LP scenario (by approx. €100 to €110) while the costs were reduced (from €2.58 in the case of mechanical labor costs and to €1,376.66 for fertilizer costs). In addition, the combination of both serves as a more viable option for diversified and economically optimized crops to be included in crop plans. It is also important that the WGP calculated higher farmer returns, even though it was run on a cropping area that was 0.02 ha smaller than that in the LP. Further, the model was tested with a parameterization process to determine and explain the role of weights and penalty functions on the quality of the model results.

Published: March 2019

ABSTRACT
Pancreatic pseudocysts and peripancreatic fluid collections extending into the mediastinum are unusual. Endoscopically, intra-abdominal pseudocysts can be drained transmurally through the stomach or duodenum depending on the location. An endoscopic ultrasound–guided esophageal approach for mediastinal pseudocysts has not been reported commonly in the literature. We report a rare case of a large mediastinal pseudocyst that was drained through the distal esophagus with eventual complete resolution of symptoms and pseudocyst.

ABSTRACT
Intraductal papillary neoplasm of the bile duct (IPNB) is a rare biliary tumor, which shares some radiologic and histologic similarities with pancreatic intraductal papillary mucinous neoplasm (IPMN). IPNB is a recognized precursor lesion of invasive adenocarcinoma. We present a case of metachronous IPNB and IPMN lesions in a patient with mucinous adenocarcinoma of the pancreas who presented with jaundice and abdominal pain. The patient was treated with surgery and adjuvant chemotherapy.
Wołosi/Vlasi z terenów Hercegowiny w świetle defterów osmańskich z XV i XVI wieku
Authors: Czamańska Ilona 
Published: March 2019

Defter's are an excellent source for historians, especially in demographic and socio-economic research, they are also very useful in researching the Vlachian communities.Analysis of material contained in Ottoman defter's from the Herzegovina area leads to the following conclusions:1. In the area of Herzegovina, in the second half of the fifteenth century, Vlachs lived in a mostly nomadic lifestyle. Their number was at least sixty thousand people.2. In the second half of the fifteenth century, many abandoned villages were recorded. Abandoned villages were gradually settled by migratory Vlachs, which contributed to their change of lifestyle on semi-settled and settled. In 1585, Vlachs - shepherds who were not associated with a village were rare.3. In the Ottoman state, Vlachs those who lead an nomadic way of living, as well as those living in the Vlachian villages, were tax-favored, paid only a lump grazing tax for the state (a filuria with allowances), and did not pay any benefits to the timar owner. In the event that they served as derbenci's or vojnuc's, they were exempted from all taxes.4. Settling in the former agricultural villages, in particular related to undertaking agricultural activities, was most often associated with an additional burden of tithing for the sipahi. Departure from pastoralism meant degradation to a group of raya, most often in these villages mixed-agricultural-pastoral management was conducted. Newly settled villages rarely received the status of the vlachian villages, because such status freed residents from additional benefits even in the case of agricultural classes.5. The flat-rate grazing tax, filuria, in the fifteenth century had a fixed value and equaled 45 akçe, while at the end of the sixteenth century it was different for various Vlachs groups and could range from 60 to 200 akçe. Considering the fact that additional fees for sheep or tents were liquidated and that the value of employment fell akçe significantly compared to the fifteenth century, the real amount of taxes did not increase, and in some cases it decreased.6. Not much on the basis of defilers can be said about the language used by the Herzegovina Vlachs. In defeats from the fifteenth century they bear mostly Slavic names, but sometimes there are also names only in the Vlachs: Radu, Bratul, Dabija, the same also applies to local names.7. Gradually, Islamization processes took place. In the fifteenth century, they are almost invisible among the Vlachs, almost all of them wore Christian names. At the end of the sixteenth century, a significant percentage of Vlachs wore Muslim names. The Islamization process seems to be faster among the Vlachs settled than the Vlachs nomads, but there is no rule.8. In the light of the defters in the area of Herzegovina, there is no difference between Muslims and non-Muslims in burdens to the state, but defters do not include the cizye, or headship, collected from non-Muslims.
Structure of the South-Western Part of the Curonian Spit
Authors: Badyukova Ekaterina N. , Zindarev Leonid A. , Lukyanova Svetlana A. , Solovieva Galina D. 
Published: March 2019

Abstract
This article addresses the southern sector of the Curonian Spit, the largest coastal barrier of the Baltic Sea. A comparative analysis of the deposits that make up parts of the Curonian and Vistula Spits is given. The detailed analysis of the geological and geomorphological structure of the southern part of the Curonian Spit suggests that, within this sector, it is not a sedimentary barrier created by wave action and Aeolian processes in the Holocene, but a part of a pre-Holocene fluvioglacial plain. Field work has shown that the ancient alluvial or fluvioglacial plain is in the lagoon shore of the Vistula Spit.
Contemporary Dynamics of the Sea Shore of Kaliningrad Oblast

Published: March 2019

Abstract
The article presents estimations of coastline retreat and advance in Kaliningrad Oblast at 85 monitoring points for a ten-year period of 2007–2017, based on monitoring data supplemented with satellite image analysis. The mean annual rate of coastline retreat and advance was estimated in general for each of the four major morpholithodynamic segments of the coastline: the Vistula (−0.2 m/year) and Curonian (−0.4 m/year) spits, as well as the western (−0.5 m/year) and northern (−0.2 m/year) shores of the Sambia Peninsula. The analysis of the shore protection measures implemented in Kaliningrad Oblast from 2007 to 2017 showed that the length of protected shore segments increased by 30% to 14.5 km, which is 10% of the total coastline. The obtained scheme of long-term mean annual rates of coastline retreat and advance clearly demonstrates an uneven distribution of eroded segments along the shores of Kaliningrad Oblast, however the sea shore of Kaliningrad Oblast is mainly susceptible to erosion (44%). Accumulative segments of the shore make up only 17% of the total coastline, and the remaining 39% of the shore is relatively stable. The results obtained demonstrate that the long-term mean annual rate of coastline retreat has decreased to −0.3 m/year from −1 m/year in the earlier period of 2000–2010. The general condition of the entire coastline of Kaliningrad Oblast can therefore be described as relatively sustainable]. The changes are related to several factors, such as an increase in the length of protected shore segments, the resumption of sand pulp dumping in the beach area by the Amber Mining Plant, and an increase in the amount of analytical data from an expanded local monitoring network.
Construction of regional geoid using a virtual spherical harmonics model
Authors: Wang Jianqiang , Wu Keqiang 
Published: March 2019

Abstract
The spherical cap harmonics (SCH) method can be used in regional geoid modeling. The core of this approach is the computation of its associated Legendre functions (ALF) with non-integer degree. However, it is unlikely to obtain a large number of zero-root values for the non-integer ALF. To overcome this problem, a new approach called virtual spherical harmonics (VSH) is proposed in this paper to transform the cap range into the whole sphere so that unlimited numbers of zero-root values can be obtained. The new approach was tested using four cap ranges with the radii of

, and geoid undulations for each of the regions are calculated from EGM2008. For each of the regions, the geoid undulations were used to construct three models with three different degrees of 20, 30 and 40. Numerical results showed that with the increase in the degree of the VSH model, the value of the maximum error decreases; and the maximum error of the model was less than 1 mm while the maximum degree is 40.
The role of Pressurized IntraPeritoneal Aerosol Chemotherapy in the management of gastric cancer: A systematic review
Authors: Garg Pankaj Kumar , Jara Maximilian , Alberto Miguel , Rau Beate 
Published: March 2019

Abstract

Background
The quest to cure or to contain the disease in cancer patients leads to new strategies and techniques being added to the armamentarium of oncologists. Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) is a recently described surgical technique which is being evaluated at many centers for the management of peritoneal metastasis (PM). The present study is a systematic review to evaluate the current role of PIPAC in the management of gastric cancer associated PM.

Methods
A systematic search was conducted in Pubmed and EMBASE database using relevant keywords and confirming to the PRISMA guidelines to identify the articles describing the role of PIPAC in gastric cancer associated PM. All the studies which were published prior to July 1, 2018 in English literature and reported the role of PIPAC in gastric cancer associated PM were included in the systematic review.

Results
The search yielded 79 articles; there were ten published studies which have reported the use of PIPAC in gastric cancer associated PM. A total of 129 patients with gastric cancer associated PM were treated in the studies. Only two studies had an exclusive cohort of gastric cancer patients while eight other studies had a heterogeneous population with a small proportion of gastric cancer patients. There was only one study highlighting the role of PIPAC in neoadjuvant setting to downgrade the peritoneal carcinomatosis index. All the studies revealed that PIPAC is feasible and has minimal perioperative morbidity, even after repeated applications.

Conclusion
There is a scarcity of English literature related to the role of PIPAC in gastric cancer associated PM. PIPAC is a safe and well-tolerated procedure which has the potential to contain spreading PM. Further studies are warranted to better define the role of PIPAC in gastric cancer associated PM.
Qualitative learning analytics to detect students’ emotional topography on EduOpen
Authors: Loperfido Fedela Feldia , Dipace Anna , Scarinci Alessia 
Published: March 2019

Abstract
What emotions can students experience in digitally mediated learning processes? In this paper, we connect Learning Analytics to the Grounded Theory in order to analyse the emotional world of students of 11 courses within the EduOpen (www.eduopen.org) massive open online course (MOOC) platform. Namely, we have used NVivo 11 Plus software and have adopted a bottom–up process to analyse the forum dedicated to students’ self-presentation from all the courses. Proceeding with the analysis, we defined a set of categories composed of a three-level system. At a more general level, we have two dimensions that we named, respectively, ‘Sentiments about shell’ and ‘Sentiments towards the pulp’. Each of these dimensions is composed of a number of ‘child’ categories and subcategories (which are the nodes in NVivo’s language). After defining the entire set of categories and categorising all the texts (which was a circular process), we run some graphs on NVivo showing the hierarchical structure of the dimensions, the relations between the dimensions and the sources and the clusters of dimensions by coding similarity. The results show how some courses are composed of more negative or more positive sentiments (towards the topic and/or the logistic arrangement of the course) and how the motivation dimension characterises the broad emotional dimension of students heavily. In an evidence-based action-research perspective, these results provide interesting suggestions to personalise the learning activities proposed to students by EduOpen.
New biomedical practices and discourses: Focus on surrogacy
Authors: Garzone Giuliana Elena 
Published: March 2019

Abstract
This study, set in a discourse-analytical and constructionist framework, explores the impact of biomedical advances on language and discourse. The main focus is on surrogacy and on the websites of ten organizations promoting it, with headquarters in various countries where this practice is legal. The discursive representation of the different forms of surrogacy and related Assisted Reproductive Technologies is discussed, focusing in particular on the communicative strategies enacted to deal with the most sensitive and controversial aspects. The analysis provides evidence of an approach that represents surrogacy, the actors and the moral issues involved in absolutely positive terms, and at the same time disregards the most problematic and controversial aspects, making recourse to some recurrent discursive frames. A further aspect investigated is the representation and denomination of the various actors involved, in a context where the spread of new reproductive technologies has introduced the possibility of significantly altering the natural mechanisms presiding over the inception of human life, and has thus triggered a process of lexical innovation and adaptation of the basic vocabulary associated with reproduction and kinship roles.
Exploring the Relationship Between Timed Up and Go Test Times and Fall History in an Inpatient Geriatric Psychiatry Unit: A Retrospective Case-Control Study
Authors: Struble-Fitzsimmons Danielle , Pinto Zipp Genevieve , DeLuca Deborah , Zhang Ning 
Published: March 2019

Background and Purpose:
Inpatient geriatric psychiatry units have the highest fall rates in the acute care setting and most falls in this population occur during the mobility tasks of transfers and ambulation. The Timed Up and Go (TUG) test includes these 2 specific functional tasks and has been used to predict falls in other geriatric populations but has never been tested in an inpatient geriatric psychiatry unit. The purpose of this study was to determine whether the TUG time measurements of inpatient geriatric psychiatry patients were associated with falling.

Methods:
The study was a retrospective chart review using a case-control design. The sample was obtained from patients admitted to 1 inpatient geriatric psychiatry unit during the 4-month study period.

Results:
The total sample size was N = 62 and included older adults with (N = 29; “fallers”) and without (N = 33; “nonfallers”) a history of falls in the 6 months prior to admission. The mean age of fallers (M = 75.8, SD = 9.6) was not significantly different from the age of nonfallers (M = 74.0, SD = 7.6), P = .424. Both groups had higher proportions of female subjects; nonfallers were 75.8% (n = 25) female and fallers were 69.0% (n = 20) female. Most nonfallers (84.8%) completed the TUG testing without an assistive device, while most fallers (48.3%) used a walker. A significant difference was found between the TUG times of nonfallers and fallers, U = 737.00, z = 3.65, P < .001, r = 0.46. Fallers took longer to complete the TUG test (median = 26.5) than nonfallers (median = 13.6). The TUG time explanatory variable was statistically significant, P = .002. Increasing TUG times were associated with an increased likelihood of patient falls (odds ratio = 1.10). The optimal TUG cutoff score was 16.5 seconds, with 79.3% sensitivity and 72.7% specificity.

Conclusions:
The TUG time measurement was found to be associated with falling. A cutoff time of 16.5 seconds is recommended to identify nonfallers from fallers in the inpatient geriatric psychiatry setting.
Do Sociodemographic Factors Relate to Walking Ability in Individuals Who Underwent Total Knee Arthroplasty?
Authors: Tanaka Shigeharu , Tamari Kotaro , Amano Tetsuya , Uchida Shigehiro , Robbins Shawn M. , Miura Yasushi 
Published: March 2019

Background and Purpose:
Knee osteoarthritis is one of the most common health problems in older adults and total knee arthroplasty (TKA) is able to improve walking ability in these individuals. There have been few studies investigating whether sociodemographic factors influence walking ability after TKA. The aim of this study was to examine which sociodemographic factors relate to walking ability in Japanese older adults following TKA during the acute stage of recovery.

Methods:
This prospective cohort study included 388 participants, from a multicenter database, who underwent TKA. The Timed Up and Go test 2 weeks after TKA was the dependent variable. Sociodemographic factors including age, sex, body mass index, marital status, and academic qualification were independent variables. In addition, type of surgery and severity of osteoarthritis were measured as confounding variables. A hierarchical multiple regression analysis was used to predict the factors that have the greatest influence on walking ability. Models were examined with and without confounding factors.

Results and Discussion:
In the final regression model, older age, conventional TKA approaches, increased severity of Kellgren-Lawrence grade, and women were associated with longer Timed Up and Go time. Academic qualification and marital status were not related to walking ability.

Conclusions:
Our results suggest that age, type of surgery, severity of osteoarthritis, and sex are related to Timed Up and Go time during the acute stage following TKA and need to be assessed.
Laboratory Evaluation on the Performance Comparison between OGFC Asphalt Reinforcement with Fibers and Modified with Nanosilica

Published: March 2019

Abstract
Open-graded friction course (OGFC) is a mixture with gap-graded aggregate that is used in pavement surfacing. This research proposes methods to improve the durability and structural contribution of OGFC mixtures through laboratory performance testing. A draindown test, a Cantabro test, a permeability test, and an indirect tensile strength test were used to evaluate the performance of OGFC mixtures. The main parameters of this research specify optimum bitumen and desirable air voids, maximum reduction of draindown and abrasion loss, and retained tensile strength ratio. It was observed that the effect of fiber in both states on bitumen percentage caused increased sensitivity to oxidation of the asphalt mixture; however, the effect of nanosilica on the reduction of sensitivity to oxidation was considerable. The effect of glass fiber in enhancing tensile strength was far higher than that of basalt fiber. In both states, nanosilica caused improved tensile strength of the mixture. Additionally, the moisture sensitivity of the OGFC mixtures with glass fiber was far better than that of the basalt fiber, and addition of nanosilica caused further improvement. The results showed a negative effect of the addition of basalt fiber alone in the asphalt mixture with a higher between percentage, necessitating the addition of nanosilica in conjunction with basalt fiber.
