An analysis of effectiveness of air heat pump operation dependent on change of external air temperature
Authors: Shapoval O. ,  Chepurna N.  , Kirichenko M. 
Published: May 2021

Currently, air-to-water heat pumps are more widely used, which due to the high coefficient of performance reduce energy consumption and negative impact on the environment. They decrease the dependency on costs of energy resources. The work is devoted to solving the urgent problem of improving the efficiency of air heat pumps at low temperature of outdoor air in winter. One of the main problems of an air heat pump is the reduction of productivity when the outdoor air temperature decreases in winter. In this paper, the effectiveness of LG Therma V air-to-water heat pump to provide apartments with heating and hot water supply was analyzed. The heat pump is reversive, which can cool or heat a heat carrier. A four-way valve swithes the coolant flows between air exchangers. On the basis of the obtained results, plots of effectivness of the heat pump dependent on outdoor air temperature are built. It is shown that the effectiveness of the heat pump significantly depends not only on the outside temperature but also on the water temperature at the outlet of the heat pump. The use of heat pumps with a high coefficient of performance can significantly reduce energy costs. The most effective are low-temperature heating systems, in which the water temperature does not exceed 45 °C. The example is floor heating, which requires very low temperature of the floor surface – up to 30 °C. At outdoor air temperature not less than milnus 7 °C the heat pump is effective at higher temperature off heat carrier at output – up to 55 °C. To provide the uninterrupted heat supply, an additional air heater is included. It covers heat load during defrosting and very low outdoor air temperature. On the basis of the conducted researches, the directions of the further experimental and field researches are planned.
Analysis of Polish norms on thermal resistance and thermal comfort for underfloor heating
Authors: Ujma A. 
Published: May 2021

In the paper, there is an analysis of the requirements for the thermal resistance of floors with underfloor heating. It corresponds to the human physiology as much as possible, creates comfortable conditions at a lower temperature of the internal air, reduces the rise of dust by reducing convective flows, allows the use of low-grade heat carriers, especially from secondary and renewable energy resources, does not take up space in the room, minimally affects the interior. However, the temperature of the heating elements is significantly higher than the room temperature. At the same time, the requirements for thermal insulation under the heating elements should be higher than for structures without heating. As the analysis of the regulations in force in Poland has shown, this is not always observed. In many cases, the heat transfer resistance is lower by 42-181 %. The percentage difference in requirements for flooers over aisles in rooms with an air temperature of 16 °C and above is 160%. It will reach 215 %, according to the requirements that will be applied from 2021. In the case of floors over unheated rooms, the percentage difference between the requirements reaches 181 %. By the new norms in 2021, this difference will reach 215 %. Also, the normative limitation on the temperature of the floor surface does not always allow providing the normative level of comfort. In rooms of categories A and B, the surface temperature of the floor must be 20-28 °C. In the case of category C it should not exceed 30 °C. The most favorable conditions are achieved when the floor surface temperature is close to 23.5 °C. PN-EN 1264-4 standard allows the temperature of the floor surface in some rooms up to 33...35 °C. Thus, to ensure energy efficiency and comfort, it is necessary to harmonize the regulations with each other.
Warm Climate Production Guidelines for Echinacea

Published: May 2021

This is one of the great moments in time when a renowned but limited perennial flower has the roof blown off of its genetic potential. The advances in Echinacea breeding we will be seeing emerge on the market in the next few years are some of the most exciting changes I've seen a long time. I'm hoping this is the beginning of not only some fantastic new hybrids but also increased awareness of some of the lesser known species.

Interplanting Secondary Crops into Existing Strawberry Fields.
Authors: Duval John R. , Golden E. A. , Whidden Alicia 
Published: May 2021

To increase the utility of land preparation, existing plastic mulch, and micro-irrigation, strawberry growers in the Plant City area often plant secondary crops among winter annual strawberries. Seeds or transplants are planted 5-6 weeks before the end of the strawberry production season, dependent on strawberry variety. This practice allows for establishment of the secondary crop while the harvesting of strawberries continues. An early start on secondary crops allows producers to take advantage of a marketing window when few other regions are producing. The most common secondary crops are squash, cantaloupe, pickles, and peppers. Strawberry is a high value, insurable crop. However, insurance policies do not allow for intercropping of strawberry with secondary crops. This practice, under current guidelines, invalidates policies.

Oak Treehopper, Platycotis vittata (Fabricius) (Insecta: Hemiptera: Membracidae)
Authors: Mead Frank W. 
Published: May 2021

The oak treehopper is fairly common on deciduous and evergreen oaks, Quercus spp., where it is sometimes sufficiently abundant to cause concern to owners of valuable shade trees. In Florida we have reports of professional pest control companies being hired to control this pest. However, damage by a colony of this species of treehopper is minor and essentially confined to small oviposition scars in twigs. This contrasts with the closely related thorn bug, Umbonia crassicornis (A. & S.), which can, when abundant, cause considerable dieback or even death of small trees.

Western Drywood Termite, Incisitermes minor (Hagen) (Insecta: Isoptera: Kalotermitidae)
Authors: Cabrera Brian J. , Scheffrahn Rudolf H. 
Published: May 2021

The western drywood termite, Incisitermes minor (Hagen), is the most common structure-infesting drywood termite in the southwestern United States. Originally described as Kalotermes minor by Hagen (1858), I. minor was reclassified into the genus Incisitermes by Krishna (1961). In California, Incisitermes minor infestations are still sometimes referred to by some pest control operators as "Kalos" and designated with a "K" on termite inspection reports. Currently, there is only one Kalotermes species in the United States (Kalotermes approximatus (Snyder), found in Florida and the southeastern U.S. north to Virginia). Some members of the Kalotermitidae are called drywood termites because colonies live entirely within sound, dead, dry wood. Drywood termites do not require any contact with the ground.

Black Twig Borer, Xylosandrus compactus (Eichhoff) (Insecta: Coleoptera: Scolytidae)
Authors: Dixon Wayne N. , Woodruff Robert E. , Foltz John L. 
Published: May 2021

The black twig borer, Xylosandrus compactus (Eichhoff), is one of the few ambrosia beetles that infests healthy plants. In Florida, orchids (Dendrobium spp. and Cattleya spp.), and avocado (Persea americana Mill.) have sustained notable economic losses (Dekle and Kuitert 1968, McClanahan 1951). Although ornamental shrubs and shade trees seldom die from beetle infestations, the loss of growth and aesthetics can be substantial. Elsewhere, the black twig borer is a serious pest of coffee, Coffea canephora Pierre (esp. var. robusta Ineac) (Brader 1964).

Pigeon Louse Fly or Pigeon Fly, Pseudolychia canariensis (Macquart) (Insecta: Diptera: Hippoboscidae)
Authors: Kern, Jr. William H. 
Published: May 2021

The pigeon louse fly, Pseudolychia canariensis (Macquart), is a common ectoparasite of pigeons and doves. The louse flies (Hippoboscidae) are obligate blood-feeding ectoparasites of birds and mammals. Both adult males and females feed on the blood of their host. They are adapted for clinging to and moving through the plumage and pelage of their hosts. Strongly specialized claws help them cling to the hair or feathers of their particular host species. Pigeon flies retain their wings for their entire adult life. Others species are wingless (like sheep keds) or lose their wings once the newly emerged adults find a host (deer keds).

The aim of this work was to study bioenergetic and ethological indicators in crossbred first-calf heifers compared to purebred first-calf heifers. The research was conducted on the first-calf heifers of Ukrainian Black-Pied dairy breed and first-generation crossbreeds obtained as a result of crossing with Brown Swiss breed, as well as, on the first-calf heifers of Ukrainian Red-Pied dairy breed and first-generation crossbreeds obtained as a result of crossing Ukrainian Red-Pied dairy with Montbéliarde breed. The purebred Black-and Red-Pied first-calf heifers prevailed over crossbreed first-calf heifers on the indicator of milk yield for 305 days of lactation by 106.45 and 218.36 kg, respectively. Accordingly, the indicators of average daily milk yield were also higher by 0.35 and 0.72 kg and the indicators of average daily milk yield adjusted by 4 % fat content per 0.15 and 0.16 kg. At the same time, the indicator of average fat content in milk prevailed in crossbreeds of Black-Pied and Brown Swiss breed by 0.08 % compared to purebred Black-Pied breeds, and in Red-Pied crossbreeds with Montbéliarde breed by 0.16 % compared to purebred Red-Pied breeds. The purebred Black-Pied first-calf heifers had an advantage by 2.04 MJ compared to crossbreeds, while the Red-Pied first-calf heifers had a slight advantage by 0.06 MJ compared to crossbreed first-calf heifers on the indicator of daily cost of exchange energy (EE). The purebred Black-and Red-Pied first-calf heifers had higher cost of exchange energy allocated with milk compared to crossbreed first-calf heifers by 0.42 and 0.82 MJ. They also had higher cost of exchange energy rates for heat products by 0.79 and 0.25 MJ. According to the energy index indicator, purebred Black - and Red-Pied first-calf heifers prevailed over crossbreeds first-calf heifers by 0.16 and 0.07 %, respectively. The same trend was observed in relation to the productive index indicator. The purebred Black-and Red-Pied first-calf heifers had a slight advantage by 0.001 and 0.002 kg adjusted by 4 % of milk fat content per 1 MJ. According to the indicators of daily behavioral reactions, no special differences between a purebred and crossbreed were found.
