The document discusses beekeeping in Croatia, including statistics on numbers of beekeepers and hives from 2005-2016. It notes an increase in new beekeepers without proper training, contributing to spread of diseases. It describes a beekeeping school program to train new beekeepers. Major challenges include varroa mites, American foulbrood disease, and lack of nutrition. Methods of integrated pest management and integrated pathology are discussed. Statistics on colony losses from 2012-2015 are provided and attributed mainly to varroa, disease, and malnutrition.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.

Diabetes is a rapidly and serious health problem in Pakistan. This chronic condition is associated with serious long-term complications, including higher risk of heart disease and stroke. Aggressive treatment of hypertension and hyperlipideamia can result in a substantial reduction in cardiovascular events in patients with diabetes 1. Consequently pharmacist-led diabetes cardiovascular risk (DCVR) clinics have been established in both primary and secondary care sites in NHS Lothian during the past five years. An audit of the pharmaceutical care delivery at the clinics was conducted in order to evaluate practice and to standardize the pharmacists’ documentation of outcomes. Pharmaceutical care issues (PCI) and patient details were collected both prospectively and retrospectively from three DCVR clinics. The PCI`s were categorized according to a triangularised system consisting of multiple categories. These were ‘checks’, ‘changes’ (‘change in drug therapy process’ and ‘change in drug therapy’), ‘drug therapy problems’ and ‘quality assurance descriptors’ (‘timer perspective’ and ‘degree of change’). A verified medication assessment tool (MAT) for patients with chronic cardiovascular disease was applied to the patients from one of the clinics. The tool was used to quantify PCI`s and pharmacist actions that were centered on implementing or enforcing clinical guideline standards. A database was developed to be used as an assessment tool and to standardize the documentation of achievement of outcomes. Feedback on the audit of the pharmaceutical care delivery and the database was received from the DCVR clinic pharmacist at a focus group meeting.

29. Varroa + xyz
„...in August and September my bees were great – lots of bees and honey, but
in October/November I don’t have anymore bees. I’ve just found few bees on
a bottom bord and frames full of honey…and I did varroa treatment…do you
have any idea where did they go? Anybody seen my bees ?....”
August
number of varroa in a hive >10 % (delaying / ineffective treatment)
September - October
number of varroa in a hive around 20 %
October - November = cleansing flights !
the bees damaged by varroa can’t return / cluster is getting smaller
varroa attack other bees in a hive / few more cleansing flights
remain just few hundreds bees /can’t keep the warmth /leave the hive
30. The best time for varroa control ?
Winter control – (November – January)
Spring control – (April – June)
Summer control – (July – September)
31. .
Winter control
3.5 % Oxal acid
Broodless colonies - Trickling 5ml/ bee gap
Temperature not below 5 C / One treatment
32. .
Spring control – no chemistry
Removing /cutting drone combs
Making splits – sealed brood / varroa control
33. Registered / legal medicaments in Croatia
• Apiguard
• Apilife Var
• Bayvarol
• Check Mite+
• Thymovar
Summer varroa control
Varroa control program – issued by Veterinary administration
Evaluation of infestation level/control of medicaments
• Formic/Lactic/Oxal acid treatment

38. AFB - the holes on the cappings
Healthy brod AFB
• scattered brood pattern
• punctured & sunken cappings
Comparative diagnosis
39. AFB - dried scales
How to check correctly for dried scales?
X
OK
40. If AFB is confirmed…
X
• Restricted area must be established with radius of 3 km
• All apiaries in protected zone must be examined
• Health certificate is needed for migratory operations
• All apiaries have to be registered
Great problem!
Abandoned apiaries
41. AFB sanitation
Shook swarm method
• early stage of AFB
• strong colony
• regular occurrence in the area
Burning
• late stage of AFB/weak colony
• first outbreak in new area
• reimbursement of 90 €
Veterinary authorities order:
42. SHB outbreaks
Italy 05.09.2014. (Calabria)
Protected area - 20 km radius
Monitoring area - 100 km radius
Italy - Sep 2015 – 6 more cases
Italy - Aug 2016 – new outbreaks
Croatia 2017
Active & pasive monitoring in 300 apiaries
44. Take home message
• Varroa/AFB/EFB control
• Spring development/Swarm control
• Queen exchanging
• Preparing for winter
• Change/adopt new approach of beekeeping
managment if it’s necessary
• Always look on the bright side of….

Editor's Notes
Von den vielen (etwa 130) in Mitteleuropa vorkommenden Glanzkäfern kommen Aufgrund Größe und Habitus nur zwei Arten für eine Verwechslung in Frage: Chychramus luteus und Chychramus variegatus. Beide Arten sind Bewohner von Blätterpilzen, nehmen aber auch Pollen auf und Chychramus luteus wurde schon in Bienenvölkern angetroffen. Chychramus variegatus ist sehr leicht an den vier dunklen halbkreisförmig angeordneten Punkte auf dem Halsschild zu erkennen.
