Abstract The insecticides were evaluated at the Kula Research Station, Maui Agricultural Park, from April to June. The field was set up in a RCB design with five treatments and four replications (blocks). Each treatment plot consisted of a single row of cabbage planted at 18 in. between plant spacing. Treatments were applied using a CO2 backpack sprayer set at 60 psi with an output of 100 gpa. One hollow cone nozzle (TX-26) was used per row The first treatment was applied five days after transplanting into the field on 23 Apr. Subsequently, six weekly applications were made until the week before harvest on the following dates: 30 Apr, 7, 14, 21, 28 May, 4 Jun. The treated check involved application of Bacillus thuringiensis aizawai (BTA) or Proclaim, using the University of Hawaii DBM resistance management protocol. The BTA product used was Mattach which was applied at 2.0 qt/acre on 23, 30 Apr, 7, 14 May. Proclaim 0.15EC was applied at 6.0 oz/acre on 21 and 28 May.

Abstract The insecticides were evaluated at the Kula Research Station, Maui Agricultural Park, from April to May. The field was set up in a CRB design with eight treatments and four replications (blocks). Treatments were applied using a CO2 backpack sprayer set at 60 psi with an output of 100 GPA. One hollow cone nozzle (TX-26) was used per row. The first treatment was applied one week after transplanting into the field on 9 Apr. Subsequently, six applications were made weekly until the week before harvest on the following dates: 16, 23, 30 Apr, 7, 14, 21 May. The treated check treatment consisted of Bacillus thuringienis aizawai (BTA) or Proclaim applied using the University of Hawaii DBM resistance management protocol. BTA products are used prior to the cupping stage of growth. Proclaim 0.15 EC @ 6.0 oz./A is applied if DBM densities exceed 1.0 larva per plant. Proclaim is used after cupping if DBM densities exceed 0.5 larva/plant and 1-2 applications are made during the two weeks prior to harvest if DBM is present. Larval thresholds were determined by making larval counts on 10 plants/treatment replication. Mattch at 2.0 qt./acre was the BTA product used and it was applied on 16 and 23 Apr. Proclaim was applied on 30 Apr, 7 and 14 May.

Abstract The insecticides were evaluated at the Kula Research Station, Maui Agricultural Park, from June to August. The field was set up in a RCB design with six treatments and four replications (blocks). Each treatment plot measured 70 ft by 7.5 ft. It consisted of four rows of cabbage on 36 in. centers and 18 in. in-row spacing. Adjacent rows were offset to allow equidistant plant spacing between rows. Treatments were applied using a tractor mounted with a PTO driven spray pump equipped with a 30 ft. boom. The boom was set with three banks nozzles that coincided with row spacing. Each group of nozzles had its own line from the main tank, therefore, spray output to specific treatment plots could be easily controlled by the sprayer operator. Treatments were applied at 45 psi with an output of 125 gpa. One TJ 60-8006 nozzle was used per row. The first treatment was made on 2 Jul, 1 day after transplanting. Subsequent applications were made on the following dates: 8, 16, 23, 30 Jul, 6, 13 Aug.

Abstract The growing number of foreign applicants looking forward to getting education in Ukrainian medical universities makes us find the ways how to improve and make effective the pre-professional training system of foreign medical applicants for further education. The article deals with the issues of the history of formation and development of the preprofessional training system of foreign medical applicants in Ukraine. On the ground of the electronic databases of the official websites of higher educational establishments, the data on years of opening first offices of the dean, departments and preparatory faculties for foreign medical applicants in Ukrainian medical universities are analyzed and systematized. Also the data on the setting up preparatory faculties at other universities who carry out licensed training of foreign students of the medical profile are presented. The data on the operating and management of such institutions in the system of the University administration are generalized. It’s revealed that during the years of its functioning the pre-professional training has changed, in particular the system was commercialized and the institutions involved in training foreign applicants have been reorganized. The modern trends in teaching foreign medical students at the preparatory faculties of the Ukrainian medical universities are displayed. Based on the analysis of the data it is concluded that the system of the pre-professional training of foreign medical applicants was set up in the 50s-60s years of the twentieth century. During this time, some positive experience in the preparation of future international medical specialists has been gained. The system of the pre-professional training of foreign medical applicants has been comprehensively improved and an effective system of managing foreign medical applicants has been created.

Shiga University opened the first data science faculty in Japan in April 2017. Beginning with an undergraduate class of 100 students, the Department has since established a Master's degree programme with 20 students in each annual intake. This is the first data science faculty in Japan and the University intends to retain this leading position, the Department is well-placed to do so. The faculty closely monitors international trends concerning data science and Artificial Intelligence (AI) and adapt its education and research accordingly. The genesis of this department marks a change in Japan's attitudes towards dealing with information and reflects a wider, global understanding of the need for further research in this area. Shiga University's Data Science department seeks to produce well-trained data scientists who demonstrate a good balance of knowledge and skills in each of the three key areas of data science.

Yam (Dioscorea spp.) is a valuable food security crop in West Africa, where 92% of the world production occurs. The availability of quality seed tubers for increased productivity is a major challenge. In this study, minitubers weighing 1, 3, and 5 g produced from virus-free single-node vine cuttings of two improved yam varieties (Asiedu and Kpamyo) growing in an aeroponics system were assessed for suitability in seed production at a population of 100,000 plants ha−1. A 3 × 2 factorial experiment with randomized complete block design and three replications was set up during the cropping seasons of 2017 to 2019 at the International Institute of Tropical Agriculture Research Station in Kubwa, Abuja, Nigeria. Results showed field establishments of 87%–97.8%. Yields differed with minituber size, variety, and cropping season; the highest was 31.2 t ha−1 in 2019 and the lowest, 10 t ha−1 in 2018 from 5 and 1 g Kpamyo minitubers, respectively. The estimated number of tubers produced per hectare by 1, 3, and 5 g minitubers was 101,296, 112,592, and 130,555, with mean weights per stand of 159.2, 187.3, and 249.4 g, respectively. We recommend using less than 6 g minitubers for seed yam production due to their high multiplication rates.

In 1957 James R. Beer, Edwin F. Cook and Robert G. Schwab, of the University of Minnesota, conducted an investigation of mammals and their ectoparasites in the Chiricahua Mountains of southeastern Arizona. The area studied included varied habitats in the general vicinity of the Southwestern Research Station of the American Museum of Natural History at Portal. An account of this investigation has now been published (Beer et al., 1959).

The blind mole-rat (Spalax ehrenbergi) is a fossorial mammal that is solitary and highly aggressive in nature. The consequent difficulties of maintaining this species in captivity have hindered attempts to gain insight into its behavior and reproductive biology. This article describes an innovative artificial tunnel system and management protocol that facilitated our study of the reproductive behavior of the blind mole-rat in captivity. The study employed a naturalistic approach that allowed the animals to establish separate territories in a seminatural tunnel system and to become familiar with each other over a period of months. This approach contrasts with previous unsuccessful attempts in which mole-rats were introduced without a period of acclimation to each other or to the experimental set-up. The results reveal that both the length of acquaintance between a pair of mole-rats and their own control of the timing of encounters are the most significant factors in reducing aggression and stress. Courtship in blind mole-rats is a lengthy process during which the animals gradually become accustomed to one another, which leads to a reduction of aggression and the initiation of positive "contact movements," eventually enabling copulation to occur. Minimal disturbance by the researcher and initiation of encounters by the mole-rats themselves appear to be the factors that led to a successful mating, pregnancy, and, 34 days later, to the female giving birth and rearing the pups in captivity.
