Beyond Feeling Sick: The Visual and Cognitive Aftereffects of Virtual Reality
Authors: Szpak Ancret , Michalski Stefan Carlo , Saredakis Dimitrios , Chen Celia , Loetscher Tobias
Published: July 2019

Developing an understanding of how virtual reality (VR) aftereffects may influence later activities could help to minimise the risk of using head-mounted displays (HMDs) for various applications. This study investigated the visual and cognitive aftereffects of using HMDs and their relationship to the reporting of VR sickness symptoms. Visual (accommodation and vergence) and cognitive (reaction time and rapid visual processing) assessments were employed before and after participants engage in a 30-minute VR table tennis game (VR group, n = 27) or went about their daily activities (control group, n = 28). VR sickness symptoms were captured using the Simulator Sickness Questionnaire (SSQ). The data showed changes in accommodation but no concurrent changes in vergence, which likely stems from decoupling accommodation and vergence in VR. Furthermore, larger changes in accommodation were linked to a greater reporting of sickness symptoms suggesting that decoupling accommodation and vergence could be more adverse than previously thought. Participants in the VR group also showed slower decision (cognitive) times, but VR did not seem to affect their movement times in a five-choice reaction time task. The novel visual and cognitive findings from this study may be valuable to obtain a better understanding of the user issues and safety around VR usage.
Stavovi i vjerovanja u alternativne religije studenata Fakulteta filozofije i religijskih znanosti s posebnim naglaskom na astrološku religiju
Authors: Tadić Stipe
Published: July 2019

Od svojih početaka čovjek je duhovno biće, a njegovom duhovnošću i religioznošću bave se različite znanstvene discipline. Nakon dominacije velikih monoteističkih religija i sekularizirane moderne, postmoderna je iznjedrila cijeli niz različitih alternativnih religija (u odnosu na dominantno kršćanstvo) objedinjenih pod nazivom New Age — slabo povezana mreža organizacija i pojedinaca, koje povezuju zajedničke svjetonazorske vrijednosti te vizija kozmičkih promjena. Kako bismo ispitali vjerovanje u ideje alternativnih religija, proveli smo anketno, empirijsko istraživanje studenata diplomskoga i preddiplomskoga studija Filozofskoga fakulteta Družbe Isusove u Zagrebu (N = 78 ispitanika). Rezultati indiciraju da, unatoč većinskomu pripadanju Katoličkoj crkvi, velik postotak ispitanika vjeruje u ideje alternativne New Age religije i astrološkoga praznovjerja.
Hrvatska recepcija enciklike Fides et ratio
Authors: Šestak Ivan
Published: July 2019

Prilog iznosi na vidjelo prisutnost enciklike Fides et ratio Ivana Pavla II. u nas, i to povodom njezine dvadesete obljetnice izlaska. S tim ciljem kronološki pokazuje osvrte na nju u našoj znanstvenoj periodici, koja se mahom vezuje uz filozofsko– teološke institucije na našem nacionalnom korpusu. Članci su većinom izlazili u časopisima Crkva u svijetu, Obnovljeni Život, Vrhbosniensia i Bogoslovska smotra, a gotovo zanemarivo na drugim mjestima. Napisi su bili prigodničarskoga karaktera, tj. izlazili su povodom objave enciklike i obilježavanja njezinih godišnjica. Riječ je o veoma dobrim prikazima čitavoga dokumenta, odnosno pojedinih njegovih dijelova u kojima je riječ o problematici kojom se autori inače bave u svojem znanstvenom radu. Oni su slijedeći okružnicu pisali o povijesno bremenitom odnosu razuma i vjere, odnosno filozofije i teologije kao znanosti o vjeri, o načelnoj otvorenosti ljudskoga duha prema istini koja je i transcendentnoga karaktera, o nužnosti filozofije za teologiju, o prirodnim znanostima i enciklici, o grozoti nihilizma koji predstavlja pravu negaciju ljudskosti te o ponudi poruke Isusa Krista koju je filozofiji pružio Ivan Pavao II. Valja spomenuti da su se pojedini autori znali i kritički osvrnuti na neke dijelove enciklike.
O strujama suvremenoga islama, svetom ratu i
čitanju Kurana
Authors: Latifi Blerim , Shtufi Kriste
Published: July 2019

Potresni masakri izvršeni tijekom građanskoga rata u Siriji i Iraku, od strane raznih grupa, posebno onih udruženih pod amblemom ISIS–a (Islamske države Iraka i Sirije) bili su povod da se mnogi poznavatelji, klerici i islamski teolozi i drugi, širom svijeta, uključe u diskursnom nastojanju kako bi uspostavili bilo kakve veze između kuranskih tekstova i ratnoga djelovanja militanata te države, samoproglašene kao novi kalifat. To nastojanje inzistira na ideji da se u kuranskom tekstu ne mogu naći nikakva opravdanja za zločine ISIS–a ni argumenti koji podržavaju pretenzije njegovih militanata da ono što čine u Siriji i Iraku nije ništa drugo nego ispunjavanje kuranske obveze, koja je u islamskoj vjeri poznata kao obveza džihada (jihad). Tko je tu u pravu? Da bi se dao odgovor na to pitanje, svakako ne i definitivno, potrebno je razmotriti niz pitanja. Prvo pitanje tiče se konteksta glavnih strujanja u suvremenom islamu. To će nam omogućiti ustanovljavanje mjesta koje grupe kao što su ISIS i Al Nusra (proizišla kao ogranak Al Qaide) zauzimaju u islamskoj doktrinarnoj tipologiji i topologiji. Drugo pitanje tiče se same koncepcije džihada. Treće je pitanje odnosa samoga kuranskoga teksta s ratom, nasiljem i mogućim načinima čitanja toga teksta. Drugo i treće pitanje omogućavaju nam da sagledamo do koje su mjere utemeljene pretenzije tih grupa da njihovi pokreti predstavljaju oživljavanje autentičnoga islama..
Rethinking Scales for Measuring Peanut Quality
Authors: Davis J.P.
Published: July 2019

Peanut quality is influenced by a complex web of factors with scales ranging from the molecular to global weather patterns impacting climate. In some cases these quality factors are well understood, measured and controlled. In others, due to time, technological or resource limitations, this is not the case. Success in current and future markets will depend on the capacity of a supply base to reliably deliver the most important quality factors, which must be well defined for a given application and cost balanced. New technologies and systems are needed to more efficiently provide data across the relevant quality scales, which will allow for better predictive tools, drive more differentiation/value in the supply base, and catalyze new market applications.
Building on our Past to Engineer the Future
Authors: Butts C. L. , Valentine H. E.
Published: July 2019

The art of engineering has had a major impact on agricultural production. Agricultural mechanization has been cited as one of the twenty most significant fetes of engineering in the 20th century. As we look through the titles of articles published in Peanut Science since its inception in 1974, we can see the breadth of engineering research and innovation that has impacted the peanut industry ranging from land preparation and seed handling to produce the crop to innovations in irrigation, harvesting, curing, storing, shelling, and transportation. While engineers have made significant impacts on the peanut industry during the 50-yr existence of the American Peanut Research and Education Society, they have not made those innovations in a vacuum, but have attacked problems with multidisciplinary teams that involved the expertise of agronomists, pathologists, entomologists, food scientists, and economists just to name a few. This article highlights some of the engineering innovations made in the peanut industry during the past 50 yr and looks ahead at what engineering obstacles must be overcome in the next 50 yr.
Not Your Grandma's Goobers: Designing the Future of Peanut Breeding
Authors: Chamberlin Kelly D.
Published: July 2019

The peanut producer has realized a 130% increase in yield since 1969, with production averaging 4,563 kgha−1 nationwide for the US in 2017. Advances in agricultural engineering, agricultural practices, and chemicals for pests, diseases and weed management have all contributed to increased peanut production efficiency and profitability. Perhaps greatest contribution to sustainable peanut production has been made by area-targeted peanut breeding programs. Charged with hitting the moving target of a 'perfect peanut cultivar', peanut breeders have managed to deliver to their customers by focusing on developing cultivars with traits of high importance such as disease resistance, high oleic acid content, early maturity, and drought tolerance, while advancing essential traits such as yield and grade. Conventional peanut breeding has provided a continuous supply of improved cultivars over the last 50 years. However, this success may be difficult to exceed if only conventional technologies continue to be used. Fortunately, recent advances in molecular technologies have resulted in the sequencing of both the ancestral and cultivated peanut genomes, opening the door for the mapping of traits and molecular marker development. By extensively phenotyping populations designed for trait mapping, steps can now be taken over the next decade to develop trait-specific markers for use in rapidly mining vast germplasm collections, efficiently identifying useful breeding material, pyramiding traits into cultivars and drastically reducing time and resources required for cultivar development. Future generations of peanut breeders will undoubtedly be well-trained in the use of such markers and will finally have the tools necessary to break through the bottle-neck of the cultivated peanut narrow genetic base. The age of peanut breeding by design may be just around the corner.

Published: July 2019

Introduction: Sagittal jaw relationship is an important parameter for orthodontic treatment planning. Angular and linear measurements both have been proposed and used in orthodontic cephalometrics to assess the sagittal jaw relationships. However, angular measurement has been questioned over the years for its reliability as a result of changes in facial height, jaw inclination and the variable positions of Nasion. So, the objective of our study was to assess the linear anteroposterior jaw relation in a sample of Nepali population using occlusal (Wits appraisal) and palatal planes as reference lines.Methods: A descriptive cross-sectional study was conducted using the lateral cephalogram of 101 individuals visiting the Department of Orthodontics, Kantipur Dental College, Kathmandu, Nepal. Individuals with Class I skeletal relation were selected using convenience sampling method. Radiographs were standardised and traced. Occlusal and palatal planes were drawn that were bisected by the perpendicular lines from Point A and Point B. The linear distances between the intersections were measured to determine sagittal jaw relations.Results: In Nepali individuals with normal ANB angle (3.05°±2.511°), the sagittal jaw relation with reference to occlusal (Wits appraisal) and palatal planes were found to be 0.203±3.343mm and 3.574±4.074mm respectively.Conclusions: Various methods has been proposed and used to assess the sagittal jaw relation and each method has its own strength and limitations. So, it is well advised to use additional cephalometric analysis whenever possible before arriving at any diagnosis and treatment plans.

Keywords: ANB angle; Nepal; palatal plane; Wits appraisal.

Published: July 2019

Introduction: Human nose is one of the important anthropometric parameters for identification of ethnicity and sex of an individual of an unknown identity. The nasal index holds a great value in anthropological studies, because it is one of the anthropometric indices acknowledged in nasal surgery as well as management. The study aims to find the mean nasal index and the nose type of dental students of Kantipur Dental College of Nepal.

Methods: This descriptive cross-sectional study was conducted among 140 dental students of age groups 17-25 years, in the Department of Anatomy, Kantipur Dental College Teaching Hospital and Research Center, Basundhara, Kathmandu. The studied population belongs to dental students of Kantipur Dental College and Research Centre. The nasal parameters including the nasal height, nasal width was measured using Digital Vernier Caliper and the nose was classified in three different types based on the value of nasal index.

Results: The mean nasal index of total population was 81.34±14.88 mm with confidence interval range of 78.85 and 83.83 mm. Mesorrhine type of nose was found to be most common among the total population. Mean nasal index in male is 84.49±12.46 mm and in female is 80.66±15.32 mm.

Conclusions: This study concludes that the mean values of nasal index of all the students falls under mesorrhine (medium) type of nose.
A Simplified Understanding of the Black Swan: Anti-phospholipid Antibody Syndrome
Authors: Vaidya Binit , Nakarmi Shweta , Joshi Rakshya , Baral Rikesh
Published: July 2019

Anti-phospholipid antibody syndrome is caused by the presence of specific antibodies against phospholipid-binding plasma proteins in serum of patient, with or without underlying autoimmune diseases, that causes prolongation of tests of coagulation. High index of clinical suspicion is required for diagnosis. Stroke or myocardial infarction in young, unprovoked recurrent deep vein thrombosis and recurrent pregnancy loss are typical scenarios where it should be suspected. Presence of non-criteria manifestations like livedoreticularis, skin ulcers, nephropathy, valvular-heart disease and thrombocytopenia adds to diagnostic clue for presence of the syndrome. Therapeutic anti-coagulation with heparin followed by warfarin is required for patients with acute thrombosis. Those with venous thrombosis are given moderate-intensity warfarin(INR 2-3), whereas those with arterial thrombosis or recurrent venous thrombosis even on warfarin are treated with high intensity warfarin (INR 3-4). Similarly, anticoagulation with heparin is advised throughout pregnancy and up to six weeks postpartum. Treatment recommendations are still not clear for asymptomatic patients and in those with non-criteria manifestations of the disease. Steroids, intravenous immunoglobulin and immunosuppressant are reported to be effective in catastrophic cases characterized by rapid small vessel thrombotic involvement of multiple organ systems. Studies are evaluating the efficacy of direct thrombin inhibitors in the management of refractory cases.

Processes responsible for variations in the isotopic composition (ΔD and Δ18O) of thermal waters of the Kuril islands arc
Authors: Kalacheva E. G. , Taran Yu. A.
Published: July 2019

Many active volcanoes of the Kuril Islands host hydrothermal systems. Their surface manifestations are represented by numerous thermal springs showing diverse chemical composition and physical-chemical parameters. Four main isotopic shifts relative to the local meteoric water line can be observed in the corresponding δD vs. δ18O diagrams. For the acid Cl-SO4 waters there is a clear mixing trend between meteoric water and volcanic vapor. The acid SO4waters demonstrate trends indicating kinetic fractionation at temperatures close to the boiling-point. Isotopic composition of the coastal springs tend to march the mixing line between meteoric and seawater. The δ18O-shift for deep thermal water is accounted to of isotopic exchange with host rock. The latitude effect revealed for meteoric waters also observed in the isotopic composition of the thermal waters.
Development of land relations in the agro-industrial complex
Authors: Khlystun V. N.
Published: July 2019

This article analyzes the results and consequences of land and agrarian reforms in Russia and investigates the main directions of land policy improvement. The dynamics of the ownership structure, as well as the forms and types of land use in agricultural organizations, indicate the incompleteness of land transformations and misunderstanding of the direction of subsequent development. An assessment of the state land policy indicates its uncertainty in a number of critical positions and the inadequate response of the land administration system to the modern requirements of socioeconomic development. Its inefficiency gave rise to the lack of information on the composition and quality of land parcels, accelerating degradation of agricultural lands, criminalization of land relations, insecurity of small agribusinesses, and unprecedented growth of latifundia, among other negative trends. Registered agricultural lands constitute a little more than 20%. The boundaries of political units are not established, which leads to land disputes and insecurity of agricultural producers’ rights. The destruction of institutions for planning and forecasting; the use and protection of lands; and land management, monitoring, re-cultivation, and anti-erosion measures all led to the desertification of large areas, progress of water and wind erosion, soil salinization, and other degradation processes. To improve the current situation, we propose that a system of urgent measures be implemented.
Environmental aspects of sustainable development
Authors: Osipov V. I.
Published: July 2019

The term "sustainable development" is based on the fundamental principle of improving human quality of life without destroying the natural environment (the biosphere). Humankind develops through the consumption of renewable (air, water, landscapes, and biota) and nonrenewable (fuel, ores, and other mineral resources) resources from the Earth. Constant renewal of resources is an essential condition for sustainable development. However, the present-day use of nature ignores this requirement, which inevitably leads to the depletion of resources, degradation of ecosystems, and global ecological disaster. This paper considers the modern level of consumption of life-supporting resources, which exceeds the permissible limits, and possible ways to prevent the approaching disaster. We draw several conclusions regarding the necessity to adopt a radically new nature-use strategy on the bases of the rational use and reproduction of resources as well as the development of new technologies of energy production from nontraditional sources.
MODEL PENDIDIKAN ANTI KORUPSI DALAM PERSPEKTIF ISLAM: TAWARAN KONSEPTUAL TCW DI ERA MILENIAL
Authors: Mukodi Mukodi
Published: July 2019

Abstrak--Artikel ini lahir dari refleksi eklektif atas persoalan korupsi yang tumbuh kembang dengan subur di Indonesia. Dalam kesejarahan Islam, korupsi telah ada dimasa kenabian, dan pelakunya dikutuk keras. Bahkan, secara metaforis Nabi Muhammad Saw pun mencontohkan Siti Fatimah, putri Nabi sendiri, jika kedapatan mencuri akan dipotong tangannya.  Hanya saja, pelaku dan perilaku koruptif tetap saja terjadi-- di masa Nabi, sahabat, Tabi’in-Tabi’in, Tabi’it-Thabi’it--hingga kini. Hasil kajian ini menjelaskan bahwa model pendidikan anti korupsi dalam perspektif Islam secara aplikatif dapat diterapkan, sebagai berikut: (1) pendidikan dan pemberantasan korupsi harus dilakukan simultan dan berkelanjutan melalui konsep tripusat pendidikan, yakni mulai dari pendidikan keluarga, sekolah dan masyarakat; (2) pendidikan anti korupsi secara aplikatif dapat didesain melalui komunitas Teenager Corruption Watch (TCW) dengan menggunakan metode role playing. Secara teknis, TCW dapat diretas di lingkungan keluarga, sekolah dan masyarakat; (3) strategi dan implementasi pendidikan anti korupsi dapat dilakukan melalui model active learning sehingga tujuan pembelajaran dapat tercapai secara efektif. Dengan demikian, generasi mellenial akan dapat terhindar dari virus korupsi yang telah mendarah daging, turun temurun dari generasi ke generasi di Indonesia.

Published: July 2019

One of the dominant death causes, which contributes significantly to the mortality of the Slovak population, is cancer mortality. In the presence of cancers, we can find geographical differences i.e. the cancer of different organs has a different frequency of occurrence in different parts of Slovakia. It may be agreed that the fight against cancers, if it is to be complex, must include a spatial aspect and this is best applied in the field of medical geography. The solution of the development of cancer mortality in Slovakia can be considered a relevant topic of geographic research. Data on cancer mortality at the district level were used from the database of the Statistical Office of the Slovak Republic. The aim of the article is to assess the spatial aspect of cancers in the districts of Slovakia applying the standardized mortality rate. The standardized mortality rate will be analysed in terms of gender structure of population. The time horizon for standardized mortality rate comparison was set for the periods of 2001-2008, 2009-2017 and 2001-2017. From the perspective of the research of this topic it is important to apply specific analytical methods which include, for example, spatial autocorrelation.

Gastro-esophageal reflux disease (GERD) is a pathological entity in which the mixture of gastric contents (with low pH because of the high content of HCl acid) and biliary juice (rich in proteolytic enzymes like pepsin and trypsin) causes lesions on the mucosa lining the esophagus. A higher prevalence of GERD was discovered in patients who had a total laryngectomy. Concerning laryngectomies with tracheo-esophageal speaking valves, it has been demonstrated that GERD is an independent risk factor for failure of this method of speech rehabilitation. The authors performed an analysis of English language articles found following a search of the major medical scientific databases (NCBI®, EMBASE®, Cochrane®) containing the following keyword string: vocal prosthesis, total laryngectomy, GERD, acid reflux, tracheo-esophageal fistula, failure. Studies showed that exposure to the protelolytic enzymes from the reflux juice increases the diameter of the tracheo-esophageal fistula and permits local granulation tissue to form. Progressively, the increasing fistula diameter leads to complications ranging from microaspiration of liquids and saliva to speaking valve expulsion or ingestion and temporary incapacity of oral feeding. Medical therapy in the postoperative period as well as long-term (6 months or more) correction of GERD (PPI therapy, H2 blockers, prokinetics) is also demonstrated to reduce the complication rate in this category of patients. GERD has a high prevalence in the total laryngectomy population of patients and it has multiple etiologic factors. In patients with tracheoesophageal vocal prostheses, GERD causes an increase in the fistula diameter – with important consequences that affect the patient's quality of life - his ability to phonate and his ability to swallow. These complications come with added costs because of the need to more frequently change the vocal prostheses with ones increasing in diameter, as well as multiple hospitalizations (even surgery to recalibrate or close the tracheo-esophageal fistula). Recognizing and treating this condition therefore decreases the risk of complications following vocal prosthesis speech rehabilitation.

Perubahan pola konsumsi menyebabkan masyarakat cenderung mengonsumsi makanan yang mengandung lemak dan kolesterol tinggi. Secara terus-menerus hal tersebut akan mengakibatkan terjadinya hiperkolesterolemia. Menurut WHO tahun 2011 diperkirakan sekitar 35% penduduk Indonesia memiliki kadar kolesterol lebih tinggi dari batas normal, artinya sepertiga dari penduduk Indonesia beresiko tinggi mengalami hiperkolesterolemia. Selain itu, kurangnya pengetahuan mengenai pengaturan diet menjadi dampak buruk sebagai resiko terjadinya berbagai penyakit degeneratif. Salah satu upaya untuk menanggulangi hal tersebut yaitu konseling gizi mengenai diet rendah kolesterol dan tinggi serat. Penelitian ini bertujuan untuk mengetahui pengaruh konseling diet rendah kolesterol dan tinggi serat terhadap pengetahuan dan kadar kolesterol total pada penderita hiperkolesterolemia. Pengumpulan data dilakukan pada bulan Februari 2019 di wilayah kerja Puskesmas Pasirkaliki menggunakan desain penelitian quasi eksperimental dengan one group pretest posttest design. Sampel dipilih secara purposive sampling dan didapat sebanyak 12 orang. Data dianalisis menggunakan uji paired sample t-test dan wilcoxon. Hasil penelitian menunjukkan ada pengaruh konseling diet rendah kolesterol dan tinggi serat terhadap pengetahuan (p=0,002) dan penurunan kadar kolesterol total (p=0,000). Disarankan agar penderita hiperkolesterolemia tetap mengaplikasikan diet rendah kolesterol dan tinggi serat sebagai upaya dalam mengontrol peningkatan kadar kolesterol darah total.

Le sulfure mixte de cérium et de lutétium Ce₄Lu₁₁S₂₂ cristallise dans le système monoclinique et appartient au groupe spatial B2/m. Sa maille, de dimensions a = 38,60 ± 0,04 Å ; b = 11,21 ± 0,01 Å ; c = 3,910 ± 0,004 Å. et γ = 91,3 ± 0,1°, contient deux unités formulaires. La détermination des positions atomiques, effectuée sur un monocristal, a fait intervenir 1 520 facteurs de structure. R = 0,032.

Les deux sites occupés par des atomes de cérium ont la coordinence huit. Un atome de lutétium est heptacoordiné, ce qui, semble-t-il, n'a jamais été observé jusqu'ici dans les dérivés sulfurés de cet élément. Les cinq autres atomes de lutétium présentent la coordinence six.

Dans cette structure, on retrouve approximativement l'organisation observée dans celle de CeYb₃S₆.

Identification of polyketide synthase gene clusters in a phage P1-derived artificial chromosome library of a Philippine strain of Streptomyces sp. PCS3-D2
Authors: Custodio Aileen Bayot , Alcantara Edwin Plata
Published: July 2019

A phage P1-derived artificial chromosome (PAC) library was constructed from genomic DNA of Streptomyces sp. PCS3-D2. Polymerase chain reaction (PCR) screening of the PAC library revealed two clones, PAC16D and P222O, which were positively identified to harbor polyketide synthase (PKS) Type I and PKS Type III gene clusters, respectively. Restriction enzyme digestion showed that PAC16D and PAC222O contained a 130 kb and a 140 kb insert, respectively. Results of sequencing and bioinformatics analyses revealed that PAC16D comprised of a full-length PKS type I bafilomycin gene cluster while PAC222O harbored truncated siderophore and putative gene clusters as well as a complete PKS III biosynthetic gene cluster. The PKS III gene cluster had three genes similar to alkyl resorcinol biosynthetic genes, however majority of the novel gene cluster had little similarity to known PKS Type III gene clusters. The successful cloning and identification of these gene clusters from Streptomyces sp. PCS3-D2 serve as the jump off point to further genetic manipulation in order to produce the insecticidal natural product in a heterologous host.
Is the European goal for defence research and technology expenditure attainable for small countries?
Authors: Lehtonen Juha-Matti
Published: July 2019

EU Defence Ministers have adopted a joint Strategy on Defence Research & Technology
(R&T) that includes a 2 % goal for defence R&T expenditure. Th is paper discusses the
feasibility of such a goal for a small country, including the motivations for undertaking
defence R&T work in small countries, and asks are they diff erent from the large countries?

New and improved weapons systems that create a technological advantage in the battlefi eld
are grounded on research in technology. However, as capability models demonstrate, there
are also other aspects of military capability than the materiel which can therefore be a topic
for research. Th rough reviewing a selection of strategy documents from large and small
European countries, the fact that only large countries have fi nancial possibilities for major
weapons system development and production is highlighted, while in small countries, this
link from R&T through development to production and operation is broken. Both defence
research and defence industrial base fi gures support this view. Small countries may still
have a number of other reasons to engage in R&T in either technology or other areas, but
these appear not to be able to suffi ciently motivate R&T expenditure even close to the 2%
level.

Published: July 2019

El objetivo de esta investigación fue evaluar materiales criollos e introducidos, para recomendar su posible uso en sistemas de autoconsumo en laderas con poca fertilidad. De agosto del 2013 a febrero del 2014 se analizaron agronómica y reproductivamente ocho variedades de arroz en La Gloria de Puriscal. Se utilizó un diseño de Bloques Completos alAzar con ocho tratamientos y cuatro repeticiones. Se evaluaron las variedades: Nira Colorado, Nira Blanco, Chin Chin, Fortuna Negro, Bluebonnet, Rexoro, Fortuna Blanco e INTA 57. Los resultados mostraron que INTA 57, Chin Chin, Nira Blanco y Fortuna Blanco, con 3,9, 3,8, 3,7 y 3,3 t/ha respectivamente, alcanzaron rendimientos significativamente superiores a las demás variedades. Además se espera que Nira Blanco e INTA 57 sean aceptadas por los productores, por tener altura de planta intermedia (1,18 m y 1,06 m, consecutivamente),por ser resistentes al volcamiento o acame y por ser poco afectadas por la Pyricularia grisea (calificaciones menores a tres las ubica como tolerantes). Es factible alcanzar niveles altos de rendimiento empleando pocos insumos para el manejo de esta enfermedad y del complejo del manchado del grano, cuya evaluación fue de niveles bajos en todas las variedades.

Published: July 2019

Se evaluaron seis cultivares de chile dulce (Capsicum annum), en la Estación Experimental Enrique Jiménez Núñez (EEEJN), ubicada en Cañas, Guanacaste, durante los meses de octubre del 2014 a mayo del 2015. Todos los cultivares evaluados presentaron frutos de tipo cónico y con maduración a rojo. Los cultivares que obtuvieron los mayores rendimientos productivos fueron FBM 10 y Dulcitico con 68,10 y 56,87 t/ha respectivamente, sin que mostraran diferencias significativas entre ellos. Todos los materiales a excepción de Dulcitico obtuvieron una mayor proporción de frutos de primera (longitud fruta ≥ 10 cm) que de segunda calidad (longitud fruto < 10 cm). El cultivar FBM 10 presentó un 52,02 % de frutos de primera, con un 47,35 % de frutos de segunda y un 0,63 % de tercera (no comercial). Las condiciones climáticas más drásticas dentro del invernadero se presentaron a la 1 p.m., en promedio la temperatura fue de 35,1 °C, la humedad relativa llegó a 54,2 % y la radiación fue de 98 watts/m2. El rubro que obtuvo el mayor costo económico fue el invernadero con 1,5 millones de colones por 1000 m2, lo que significa un 50 % de la inversión inicial. El cultivar de chile dulce que obtuvo la mayor utilidad neta, fue el FBM 10 con 2,11 millones de colones por cada 1000 m2. Esto se debió a que obtuvo los mayores ingresos totales de frutos de primera y segunda, con 3,08 y 2,10 millones de colones respectivamente, superando en ingresos totales al cultivar testigo (Nathalie) por 1,08 millones de colones/1000 m2.
