    Opis:
    A well preserved specimen of the theropod Ceratosaurusfrom the Upper Jurassic Morrison Formation of western Colorado was recently described and given the name C. magnicornis. The systematics of the genus is outside the scope of the present study but, as a generally accepted basal tetanuran, the braincase was CT scanned to provide a description of the endocranium, inner ear, pneumatic, and venous sinus systems in a primitive member of this clade. Five major subregions of the theropod endocranium are distinguished for the purpose of simplifying cranial computed tomographic interpretation and to provide a systematic means of comparison to other endocrania. The skull morphology of Ceratosaurus influences the overall braincase morphology and the number and distribution of the major foramina. The low pontine angle and relatively unflexed braincase is considered a more primitive character. The orientation of the horizontal semicircular canal confirms a rather horizontal and unerect posture of the head and neck. As in birds, the narrower skull morphology of Ceratosaurusis associated with fewer cranial nerve foramina. Additionally, the maxillary dominated dentigerous upper jaw of Ceratosaurusis felt to share with the alligator a large rostrally directed maxillary division of the trigeminal nerve and a small ophthalmic branch. The upper bill of birds, being dominated by the premaxillary and lacking teeth, is innervated predominantly by the ophthalmic division of the trigeminal nerve. For this reason, avian−based cranial nerve reconstructions are felt to be inappropriate for basal theropods.Ceratosaurusskull pneumatization and possible evidence of olfactory conchal structures is on the other hand very avian in character. Based on computed tomography, Ceratosaurusis determined to have possessed a typical basal theropod endocranium and bipedal vestibular system similar to Allosaurus.

    The study identifies factors influencing the importance consumers in the Republic of Korea attach to food poisoning resulting from eating vegetables, fruits, or nuts. Survey data collected from 1,100 females residing in the seven major urban centers are used to estimate the equations. Results are used to calculate probabilities associated with the specific opinions held by respondents with regard to, among others, demographic and economic characteristics and preferences about food and food production methods.
    Celem pracy było zidentyfikowanie czynników wpływających na zwracanie uwagi przez konsumentów w Republice Korei na zatrucia pokarmowe spowodowane jedzeniem warzyw, owoców lub orzechów. Modele wyliczono na podstawie badań ankietowych przeprowadzonych wśród 1100 kobiet zamieszkujących w siedmiu wielkomiejskich obszarach Republik Korei. Wyniki pokazały prawdopodobieństwo z jakim występują zmiany opinii respondentów co do znaczenia m.in. cech demograficzno-ekonomicznych oraz preferencji dotyczących żywności i sposobu jej produkcji.

    Genotypic correlations and path–coefficients were determined for nine yield-related agronomic traits using 10 accessions of scarlet eggplant. There were significant (p < 0.05) differences among the 10 accessions for all traits and differences were largely due to genetic effects. There was no significant positive correlation of any trait with fruit yield, but number of days to flowering, plant height at flowering and number of days to fruit maturity were significantly (p < 0.05) and negatively correlated with fruit yield. Path-coefficient analyses showed that number of fruits per plant had the highest direct effect on fruit yield, followed by fruit diameter...

    Opis:
    The aim of this study was to determine the effect of 3 sire bulls from different genetic lines on the yield, chemical and mineral composition of milk produced by their daughters that belonged to black and variegated cattle kept in Kazakhstan, in the consecutive lactations and milking seasons. The research included 60 dairy cows, whose average share of HF breed genes did not exceed 50%. The cows were kept on a dairy farm called Wiktorowskoye, located near Tarnov (Kazakhstan). The highest milk yield, fat and protein content were recorded for the offspring of the bull Hamlet (H-239). The lowest body weight was achieved by daughters of Hamlet (H-239) and was significantly different from the other cows at p£0.01 and p£0.05. The milk yield per body weight (bw) showed that cows in the 3rd lactation produced 911 kg of milk/100kgb.w.. Daughters of Hamlet (H-239) distinguished themselves by the best milk yield to body weight conversion rate of 985 kg/100 kgb.w.. The ratio of protein to fat was satisfying and ranged from 0.82 (1st lactation) to 0.80 (3rd lactation). Cows from the group H-239 produced milk with the highest content of fat. In the 1st lactation, it equalled 3.95%, rising to 4.02% in the 3rd lactation. Depending on the milking season, the highest fat content was in the AU (4.02%) and WI seasons (3.99%) and the lowest one occurred in the SU season (3.87%). The highest protein content was observed in cows of group M-370 and amounted to 3.29% (primiparous cows) and 3.24% (3rd lactation) as well as 3.52% (WI) and 3.46 (AU). The highest content of SSC (2,464 thousand/cm3) was found in cows of group B-361 in the WI season, with statistical differences p £0.01 and p £ 0.05. The content of FFA was the highest in daughters of the bull M-370 bull, followed by the offspring of the bull H-239.

    Opis:
    Palynofacies analyses from Bonyere Well No. 1 in the Tano basin, western Ghana has revealed five palynofacies associations (I – V) based on the percentage relative abundances of the sedimentary organic matter (SOM). The palynofacies associations reflect deposition in a fluvio-deltaic (oxic) environment, a distal dysoxic-anoxic shelf environment, a proximal dysoxic-suboxic environment, nearshore (oxic) and a fluvio-deltaic/nearshore environment with high oxygen levels and low preservation rates respectively. Based on marker palynomorphs, Campanian – Maastrichtian age has been assigned to sediments within the interval (1800-10 ft) – (90-100 ft), Turonian – Lower Senonian (Santonian) age between (3160-70 ft) – (1980-90 ft) and Aptian age between the interval (8140-50 ft) – (3340-50 ft). The absence of the elater-bearing pollen which are typical Africa-South America (ASA) elements for the Albian – Cenomanian age is indicative of an unconformity between the Aptian and Turonian sediments.

    Opis:
    This study investigated genetic diversity among 23 cassava genotypes  in two-agro-ecological zones (Ibadan and Mokwa), Nigeria. The experiment was conducted using a randomized complete block design with three replicates. The cassava genotypes were evaluated for tuber yield, fresh weight of tuber, number of tu- bers, tuber girth and length, dry matter and chlorophyll concentration. The data collected were subjected to analysis of variance and differences among the genotypes were computed using Duncan’s multiple range test. Single linkage cluster and FASTCLUS  analysis were used to group  the cassava genotypes. Genotypic and phenotypic coefficient of variability, heritability and genetic advance were also evaluated. Genotype, environ- ment and genotype × environment interaction (GEI) were significant (P < 0.01) for most of the traits evalu- ated. The magnitude of the environment was higher compared to genotype and GEI. Comparative mean per- formance varied from location to location. Tuber yield ranged from 0.32 for 92/0325 to 0.90 kg for 99/3073 with mean of 0.58 kg, and 0.16 kg for 82/00058 to 0.67 kg for 98/0581 with mean of 0.35 kg in Mokwa. Higher genotypic and phenotypic coefficients of variability were observed in Ibadan than Mokwa, for most of the characters. The interrelationships among the characters revealed the superiority of some cassava genotypes for a character  in one location and not in the other location. However, breeding potentials exists among the cassava genotypes across the two environments.

    Opis:
    Soil temperature is an important factor in biogeochemical processes. On-site monitoring of soil temperature is limited in spatio-temporal scale as compared to air temperature data inventories due to various management difficulties. Therefore, empirical models were developed by taking 30-year long-term (1985-2014) air and soil temperature data for prediction of soil temperatures at three depths (5, 15, 30 cm) in morning (0636 Indian standard time) and afternoon (1336 Indian standard time) for alluvial soils in lower Indo-Gangetic plain. At 5 cm depth, power and exponential regression models were best fitted for daily data in morning and afternoon, respectively, but it was reverse at 15 cm. However, at 30 cm, exponential models were best fitted for both the times. Regression analysis revealed that in morning for all three depths and in afternoon for 30 cm depth, soil temperatures (daily, weekly, and monthly) could be predicted more efficiently with the help of corresponding mean air temperature than that of maximum and minimum. However, in afternoon, prediction of soil temperature at 5 and 15 cm depths were more precised for all the time intervals when maximum air temperature was used, except for weekly soil temperature at 15 cm, where the use of mean air temperature gave better prediction.

    Opis:
    Purpose: Weed interference is a constraint in agricultural practice. The crop-weed interaction has been extensively described in literature, but the weed-weed interaction and their potential usage in crop production have not much been understood. In this paper, the interactions of allelochemicals of the weeds which cause troublesome in crop production and ecosystem against weeds, crops, and pathogens are described. Principal results: Weed allelochemicals are classified into many chemical classes, and the majority is consisting of phenolics acids, alkaloids, terpenes, flavonoids, long chain fatty acids, lactones, and other volatile compounds. Type of weed allelochemicals and their doses are varied among weed species. Some allelochemicals such as catechin (+/-) have been reported to be responsible for weed invasiveness. Some crops exude germination stimulants to parasitic weeds such as Striga spp. and Orobanche spp. In contrast to their negative impacts on crop production, many weeds can be exploited as promising sources to control harmful insects, fungi, bacteria, and weeds. For instance, Ageratum conyzoides is a destructive weed in crop production, but it exerted excellent insecticidal, antifungal, and herbicidal capacity and promoted citrus productivity in A. conyzoides intercropped citrus orchards. Major conclusions: In general, weeds compete with crops by chemical pathway by releasing plant growth inhibitors to reduce crop growth. Weed allelochemicals may be successfully exploited for pest and weed controls in an integrated sustainable crop production. Some weed allelochemicals are potent for development of natural pesticides.
