Foliar anatomical studies of Andropogon gayanus - Andropogon tectorum complex in Southwestern Nigeria

Foliar epidermal studies were carried out on accessions of Andropogon gayanus-Andropogon tectorum complex collected in Southwestern Nigeria with a view to providing additional characters of the two species of Andropogon to enhance the understanding of the taxonomic relationship between the two species. The epidermal preparation of the adaxial and abaxial surfaces of the leaf blade was made from the median part of well-matured leaf samples by the scrapping method. The analysis of both qualitative and quantitative characters revealed that study revealed that the costal zones of both adaxial and abaxial surfaces of all accessions studied showed similar features with little or no variation in their expression; epidermal cells are mostly rectangular with wavy walls, and the stomata encountered are paracytic. There was a unique occurrence of cluster of cells at the base of the macro hairs present in A. gayanus which is a diagnostic feature for its accessions collected. Kiwani, an unidentified polyploid accession, has the highest number of bands, the stomata are bigger, which is consistent with gigas effect occasioned by its polyploidy status. Glandular trichomes were present in both diploid and tetraploid of A. tectorum, a diagnostic feature for the species.

Two new species of feather mites (Acarina: Psoroptidia) from the Huet's fulvetta, Alcippe hueti (Passeriformes: Leiothrichidae), in China

Two new feather mite species collected from the Huet's fulvetta, Alcippe hueti (Passeriformes, Leiothrichidae), in China are described: Proterothrix dinghushani sp. n. (Proctophyllodidae) and Trouessartia pauciseta sp. n. (Trouessartiidae). Males of P. dinghushani have a pair of lateral hysteronotal sclerites and a closed pentagonal sclerotized frame in the postero-median part of propodosoma. Females of this species have the sternum 1/4 of the total length of epimerites, and the terminal cleft exceeds half of the length of the lobar shield. Both sexes of T. pauciseta have a distinctive character, the absence of 3 pairs of hysteronotal setae (d1, d2, and e2), that clearly differs this species from all previously known species of the genus.

Description of the larva of Protaetia (Cetonischema) speciosa speciosa (Adams, 1817) (Coleoptera: Scarabaeidae)

The larva of Protaetia (Cetonischema) speciosa speciosa (Adams, 1817) is described and illustrated for the first time. The larvae of the subgenus Cetonischema Reitter, 1899 have a thoracic spiracle same size as a spiracle of abdominal segments VII–VIII, larger than spiracles of abdominal segments I–VI; spiracles of abdominal segments I–VI are the same size; venter of last abdominal segment with short setae and a single of long to short setae on the lateral sides and at the apex, as well as areas without setae and spines in median part. The larva of Protaetia s. speciosa differs from larva of P. speciosissima (Scopoli, 1786) by a number of pali and it chaetotaxy in the row in palidia, and by a chaetotaxy of head capsula.

Evaluasi kesesuaian jenis dan penataan tanaman pada lansekap jalan di Jalan Dharma Giri Gianyar

Street infrastructure is now equipped with various kinds of plant elements that known as streetscape, so the existence of the street is not monotonous. Beside the landscape of the street also has a function as a medium for green open space. Therefore, the selection of plant species and arrangement of plants in streetscape must be in accordance with the criteria of plant morphology of the streetscape. Evaluation was carried out based on the problems that occur in the suitability of species and arrangement of plants in the landscape of the street. The purpose of this study was to determine the existing conditions found on the streetscape on the Dharma Giri and to determine the suitability of species and arrangement of plants as a streetscape plant. The method used in this research was field survey with a qualitative approach. The results showed that the general condition of the vegetation and plant selection in Dharma Giri streetscape was almost in accordance with the growing conditions needed by the plants. It conditions generally grow well. Mostly the plants were planted in the median part of the street and also in both side of the street which was also able to adapt with direct sunlight exposure and was not require high intensity of watering. It was also observed from the aspect of arrangement using the approach of the three principles of design which includes themes, rhythm, and balance. However, the plant maintenance activities needs to be improved so it possibly maintained the esthetics and function of the streetscape.

Ainsliaea daheishanensis (Asteraceae): a new species from China

In this work, we describe a new species, Ainsliaea daheishanensis Y.L.Peng, C.X.Yang & Y.Luo, based on morphological traits. The new species was discovered in the mountains of Yunnan, near the border between Myanmar and China. The new species differs from the phenotypically closely-related Ainsliaea foliosa Handel-Mazzetti in the morphology of the leaf veins and phyllaries, those having a protruding abaxial reticulate pattern in the lower and median part of stem with white hairs and narrow inner phyllaries. A key to the three closed Ainsliaea species occurring in China is provided.

Multifunctional Medical Recovery and Monitoring System for the Human Lower Limbs

In order to develop multifunctional medical recovery and monitoring equipment for the human lower limb, a new original mechanical structure with three degrees mobility has been created for the leg sagittal model. This mechanism is integrated in the equipment and includes elements that have similar functions to the different anatomic parts (femur, median part), leg, and foot. The independent relative rotation motion between the previously mentioned anatomic parts is ensured. The femur may have an oscillation rotation of about 100° relative to the trunk. The median part (leg) alternatively rotates 150° relative to the superior segment. The lower part (foot) is initially placed at 90° relative to the median part and may have an alternative rotation of 25°. Depending on a patient’s medical needs and their recovery progress, device sensors provide varying angular amplitude of different segments of the human limb. Moreover, the mechanism may actuate either anatomic leg segment, two parts, or all of them.

LEADING SYSTEMS AND VIABILITY OF CITRIC BUDS IN HYDROPONICS

ABSTRACT The purpose of this experiment was to evaluate the production of budstocks and the viability of the buds of the ‘Valencia’ and ‘Pera’ orange tree varieties in a hydroponic system. The experiment was arranged in a completely randomized design in a 2 × 3 factorial scheme. The two orange varieties were grafted onto the Rangpur lime tree with three leading systems (single stem, two stems, and three stems) and three replications of 10 plants per plot. The time that elapsed between pruning the stems at 40 cm and the first collection, as well as the time between each harvest were determined. The number of buds in the median part of the stems and percentage of viable buds in each leading system were also measured. This was determined after performing inverted T budding on the Rangpur lime tree rootstocks and verifying that the procedure was successful. The production of citrus plant budstocks is feasible in a hydroponic system.
