The aim of this study, which involved a field experiment conducted in north-eastern Poland, is to evaluate the phytometric parameters, yield, and biological value of fruit of three tomatillo cultivars grown in soil mulched with black PE (polyethylene) film and covered with PE film and non-woven PP (polypropylene) fabric. A two-factor field experiment was conducted in 2015 and 2017–2018 in the Agricultural Experiment Station owned by the University of Warmia and Mazury in Olsztyn. In the control treatment, tomatillo plants were grown without protective covers or mulch. Tomatillo fruits were harvested gradually, upon physiological maturity, which was determined based on changes in the color of the peel and calyx, and the aroma. The growth and development of tomatillos were evaluated based on plant measurements performed in the field. The chemical composition of tomatillo fruits was analyzed at the stage of full fruiting. During the three-year study, the weight, vertical diameter, and horizonal diameter of fruit were highest in cv. ‘Rio Grande Verde’ and lowest in cv. ‘Purple’. The combined use of mulch and plant covers accelerated fruit ripening. The total and marketable yields of tomatillo fruit were highest in cv. ‘Rio Grande Verde’ and lowest in cv. ‘Purple’. The fruit of cv. ‘Purple’ had the highest content of dry matter, total sugars, extract, β-carotene, and total polyphenols.

In a field experiment, it was established that of the three herbicides we studied in soybean crops, Dual Gold is the most effective. Its use increases, in comparison with the control, the number of beans per plant by 2.2 times, the number of seeds by 2.4 times, and the mass of seeds by 2.9 times. The least efficient is Fabian. In terms of most indicators of the yield structure, it is reliably inferior to Dual Gold. Zenkor is slightly inferior in efficiency to Dual Gold. The differences between them are not reliable. High efficiency (at the level of Dual Gold) was shown by the combined use of Zenkor and Fabian herbicides in doses reduced by 20%.

In this study, the phosphorus (P) fertilizing effects of struvite, one thermochemical-treated sewage sludge ash (SSA) based on Ca-P (Ca-SSA) and one full sulfuric acid-digested SSA based on Al-P (Al-SSA) were analysed in comparison to triple superphosphate (TSP) and a control treatment (CON) without P application in a two-year field experiment. In the field experiment, the effects of the recycling products on crop yield, P uptake and labile soil P fractions were analysed. In addition, the effect of nitrogen and magnesium contained in struvite was investigated in the second year of the experiment compared to TSP and CON. In the first year, spring barley was cultivated in the field experiment; and in the second year, it was forage rye followed by sorghum. In the second year, the relative P effectiveness (forage rye, sorghum) of the recycling products compared to TSP increased in the order: Ca-SSA (81%, 91%) ≤ Al-SSA (91%, 96%) = struvite (102%, 110%). In addition, an magnesium fertilizing effect of struvite could be demonstrated. The results show that the recycling products from wastewater treatment are appropriate to substitute rock phosphate-based fertilizers.

A taxonomic revision of the Nystiellidae from Brazil, including samples from the Rio Grande Rise, South Atlantic, was performed based on shell morphology. Five genera and 17 species were recognized. For the richest genus,Eccliseogyra, the three species previously recorded from Brazil were revised:E. brasiliensisandE. maracatu, previously known only from their respective type series, were re-examined. Newly available material ofE. maracatuexpanded the known geographic range of this species to off south-east Brazil.Eccliseogyra nitidais now recorded from north-eastern to south-eastern Brazil, as well as from the Rio Grande Rise. Three species ofEccliseogyraare newly recorded from the South Atlantic:E. monnioti, previously known from the north-eastern Atlantic, occurs off eastern Brazil and on the Rio Grande Rise; its protoconch is described for the first time, confirming its family allocation.Eccliseogyra pyrrhiasoccurs off eastern Brazil and on the Rio Grande Rise, andE. folinioff eastern Brazil. The genusIphitusis newly recorded from the South Atlantic.Iphitus robertsiwas found off northern Brazil, although the shells show some differences from the type material, with less-pronounced spiral keels. Additional new finds showed thatIphitus cancellatusranges from eastern Brazil to the Rio Grande Rise, and Iphitusnotiossp. nov. is restricted to the Rio Grande Rise.Narrimania, previously recorded from Brazil based on dubious records, is confirmed, including the only two living species described for the genus:N. azelotes, previously only known from the type locality in Florida, andN. concinna, previously known from the Mediterranean. A third species,Narrimania raquelaesp. nov. is described from eastern Brazil, diagnosed by its numerous and thinner cancellate sculpture. To the three species ofOpaliopsispreviously known from Brazil, a fourth species,O. arnaldoisp. nov., is added from eastern Brazil, and diagnosed by its very thin spiral sculpture, absence of a varix, and thinner microscopic parallel axial striae.Papuliscala nordestina, originally described from north-east Brazil, is recorded off eastern Brazil and synonymized withP. elongata, a species previously known only from the North Atlantic.

The field research was set up on chernozem soil at the Látókép AGTC KIT research area of the University of Debrecen. The study focused on yield, water utilization, nutrient reaction and the amount of yield per kg fertilizer of corn hybrid NX 47279 in 2011 and 2012. Based on the yield results it can be concluded that the largest yield in 2011 was 15 963 kg ha-1 at level N120+PK, while in 2012, the maximum yield amounted to 14 972 kg ha-1 at level N90+PK. Surplus yield per kg fertilizer proved that in 2011 level N30+PK resulted in the highest surplus yield (42.3 kg kg-1) compared to the control treatment. In 2012, yield growth was 18.0 kg kg-1 compared to the control treatment. We measured at level N60+PK 17,5 kg kg-1 compared to at level N30+PK, at the N90+PK 17,7 kg kg-1 compared to at level N60+PK. level N30+PK kg kg-1, 17.5 kg kg-1 at level N60+PK and 17.7 kg kg-1 at level N90+PK compared to the control treatment. Results of the regression analysis showed that the amount of nitrogen fertilizer was 117 kg ha-1 in 2011 and 111 kg ha-1 in 2012 in order to reach maximum yield. Doses of fertilizers above the amounts previously mentioned resulted in yield decrease. Our results indicated that in the drought year of 2012 the hybrid used available water more efficiently than in 2011. The hybrid produced 59 kg ha-1 yield in 2012 and 51.9 kg ha-1 in 2011 at an optimum nutrition level.

Introduction: Preterm delivery is of considerable concern to clinicians and researchers being a leading cause of infant morbidity and mortality in the industrialized countries and also contributes to substantial complications among survivors. Sub-Saharan Africa, including Nigeria accounts for significant proportion of preterm births, with over million deaths due to complication of prematurity. Objectives: The study aimed to determine the prevalence and associated morbidities of preterm deliveries at the University of Maiduguri Teaching Hospital, Maiduguri, North-Eastern Nigeria. Patients and methods: This is a retrospective review of neonates delivered before 37 completed weeks of gestation and admitted into the Special Care Baby Unit (SCBU) of the University of Maiduguri Teaching Hospital, from 1st January 2008 to 31st December 2015. Results: There were 3435 admissions into the Special Care baby Unit (SCBU) during the 8 year period. Out of these 1129 were preterm babies giving a prevalence of 32.9%. Of the 1129 preterm babies managed in SCBU, 714 case records were retrieved and analyzed giving a retrieval rate of 63%. There were 372 (52.1%) males and 342 (47.9%) females; with the male to female ratio of 1:1.08. There were 17(2.3%) extreme low birth weight  (<1000g), 288 (40.3%) very low birth weight (1000-1499 g), 406 (56.9%) low birth weight (1500- 2499 g) babies. The range of admission weights was 700-2500g with mean of 1600±900g. Conclusion: The burden, complications and mortality from preterm newborns remain significant public health challenges to care givers in Nigeria.

The effect of several strategies - alone and integrated - on the control of the Phytophthora sp. fungae, which causes radical rotting of papaya fruits, was evaluated under nursery conditions. The experiment took place between August 1994 and March 1995 at the University of Costa Rica's Estación Experimental Fabio Baudrit, located in Alajuela, Costa Rica. The treatments applied were: sun heat for 30 days; organic fertilizer made from hen droppings; etridiazole fungicide; and the following combinations: sun heat + etridiazole + organic fertilizer; etridiazole + organic fertilizer; sun heat + etridiazole; sun heat + etridiazole + organic fertilizer, and finally, an inoculated control treatment. Soil rows were made, and then they were innoculated with the pathogenic agent, and finally the aforementioned treatments were applied. The treated soils were bagged separately. The Solo Sunrise Hawaiian variety was planted in bags. The percentage of gerrnination, stem diameter at soillevel, plant height, radical system fresh weight, and severity of radical rotting were evaluated three months later. In addition, the effect of the treatments on beneficent soil microorganism populations (actinomyces, protozoa, bacteria, and fungi) was evaluated, as well as those of pathogenic populations. Organic fertilizer increased plant strength. All treatments affected germination; the innoculated control had the greatest germination percentage. Treatments containing organic fertilizer affected germination most.

Background: Ketamine and propofol in a single syringe are reported to create an admixture used for balancing cardiorespiratory effects during induction of general anesthesia. This study aimed to assess the clinical practice and knowledge of “ketofol” among anesthesia providers.Methods: A cross-sectional institutional-based study was conducted among anesthesia providers. Data abstracted format was prepared and distributed to senior anesthetists, junior anesthetist postgraduate students, and undergraduate students. The study was conducted from January 1, 2019, to January 30, 2019. Descriptive statistics and binary logistic regression were performed for frequency distribution and to determine the association, respectively.Result: From a total of 133 participants included in the study, the majority, 88 (66.2%), were men and 75 (56.9%) had 0–2 years of experience. More than two-thirds of participants, 105 (78.9%), have never had a seminar or educational session about combined use. Lack of experience among 11 participants (8.3%) was one of the reasons for not using “ketofol” followed by lack of knowledge among three (2.3%) participants. The majority of participants, 112 (84.2%), prefer ketamine and propofol to be administered one right after the other with separate syringes and the ratio to be 1:2, 64 (48.2). There was no significant association observed between sociodemographic and other characteristics and the practice of “ketofol.”Conclusion: In this study, nearly half of the participants rated their knowledge at the average level, and the study identifies that there is clinical knowledge and practice gap among anesthesia providers working in the University of Gondar Comprehensive Specialized Hospital (UOGCSH). Preparing educational sessions regarding “ketofol” for addressing identified barriers is among the recommendations forwarded to UOGCSH.

Abstract Shallot is an important cash crop in Indonesia. However, its productivity is relatively low, due to the attack of the onion caterpillar (Spodoptera exigua Hubner). This study aimed to identify the effect of the application of control techniques on the population, damage intensity, and shallots yield. This research was conducted by field experiment. Control treatment consisted of covering shallots by using gauze/net and insecticide treatment with active ingredients of profenofos, metomil, and carbosulfan. The research variables consisted of the population and the damage intensity of S. exigua, as well as the yield of shallots. The results showed that the caterpillars population of S. exigua was found at 16 DAP and increased up to before harvest at 44 DAP. Covering shallots with gauze effectively suppressed the population of S. exigua (0.0 per hills), followed by treatment with profenofos (0.14 per hills), carbosulfan (0.15 per hills), and methomyl 0.32 per hills). The damage intensity of S. exigua in the plot gauze covered was 0%, lower than 32%, 25%, 12%, 10%, respectively, in the control plot, treatment of metomil, carbosulfan, and profenofos. Covering shallots with gauze also increased the weight of wet-harvested tubers (50.83 g per hills).
