Mark Thomas - The editor and big chief of The Dubrovnik Times. Born in the UK he has been living and working in Dubrovnik since 1998, yes he is one of the rare “old hands.” A unique insight into both British and Croatian life and culture, Mark is often known as just “Englez” or Englishman. He is a traveller, a current affairs freak and a huge AFC Wimbledon fan.


The largest infrastructure project in Croatia, the Peljesac Bridge, is nearing completion and now a date is known when the bridge will physically connect on side of the mainland to the other.

The final segments of the bridge are being completed and on the 28th of July the bridge will physically connect the mainland with the Peljesac peninsular.

The total width of the bridge is 22.5 meters, it is 2.4 kilometres long and 55 meters high. The project envisages four traffic lanes, and the first vehicles could cross it in March next year.

At the same time, works on the access roads to the bridge are in full swing. Thus, the Greek company Avax have successfully completed the excavation of the Polakovica tunnel, 1240 meters long near Ston on Pelješac. The Polakovica tunnel is part of the 4th phase of the Ston bypass and, together with the Ston bridge and the second Supava tunnel, forms the most complex part of this project.

The access roads together with the Ston bypass are 28 kilometres long. They contain four tunnels, three smaller bridges and two viaducts, and about 600 workers are employed on them.


In the Dubrovnik-Neretva County, 13 new cases of coronavirus infection were recorded in the last 24 hours. These are five males and eight females, all from Dubrovnik.

Six people made a full recovery - three from Dubrovnik, two from Ston and one person from Konavle.

In the last 24 hours, 293 samples were processed, and since the beginning of the pandemic, a total of 90,143 samples have been analysed.

Four people tested positive for coronavirus were hospitalized in the Dubrovnik General Hospital.

There are 279 people in self-isolation, and in the last 24 hours, three violations of the self-isolation measure were recorded at the border.


In today's world, many common and specialty items can be purchased made of either metal or plastic. Some people have preconceived notions that either plastic or metal is the better material, although neither is “better” across the board. Plastic is better suited for some items, metal for others. With still other items, one might be less expensive than the other although they work equally well. Even in such cases, one can be better for some people because of the way in which they use the item.

In a laboratory setting, the decision about whether metal or plastic is more suitable becomes even more complicated. Different types of plastics are available for different uses. Certain chemicals can't be stored or mixed in a metal container, while others can melt through a container made of the wrong kind of plastic. It's always important to determine the right material for any piece of equipment based on how the item is intended to be used, and provide proper employee training on what the tool can and cannot do based on the material it is made of.

Corrosion Factors

The biggest problem with metal is that it corrodes, and can corrode quite quickly in the presence of certain acids, alkalines, or chemicals used in a lab setting. There are certain metals which might work well with certain chemicals, but even they corrode over time due to humidity. Contrary to popular belief, even stainless steel can eventually begin to rust, which can become a problem in a sanitized lab setting. Plastic won't corrode like metals do, but can break down at the molecular level when exposed to certain chemicals or energy sources. When used properly, however, plastics can last a lifetime and be cleaned back to “same as new” condition.


Durability is a similar yet different issue than corrosion resistance. Metal tends to be a stronger material against most common forces, such as falling on a concrete floor. Certain types of plastics can be stronger in certain conditions, other types will easily break in the same scenario. It has to do with how being hard can mean a different thing than being hard to the point of brittleness, and being soft can allow for better resilience against some forces yet allow an item to be easily damaged under other conditions.

Although such general terms are the standard in some industries for judging whether to choose metal or plastic tools and equipment, a laboratory setting usually has a different set of standards based on the type of lab it is and what the people working there do. The people working in lab settings are expected to know the difference between types of plastics and metals and what they are used for. This concept applies to large industrial machinery and small items such as beakers and flasks, or even hand tools such as calipers and stirrers.

Electrical Conductivity

An important aspect of metal versus plastics is electrical conductivity. Different metals are better at conducting electricity, but most do conduct it to some extent. Plastics do not conduct electricity, although not all plastics of certain thicknesses are considered adequate insulation against it. Such properties make plastic universally better in certain applications. The wiring for any machine which uses high voltage is going to be adequately insulated, especially if water is part of the machine's function, but plastic parts may be more suitable if there is a chance of electricity skipping from the wiring contacts to the parts the operator touches.

Expense of Manufacture

Generally speaking, plastic is less expensive than metal. There are exceptions to the rule, particularly when comparing intricate injection molded custom plastics when simple bent formed metal parts would be suitable. Generally speaking, the manufacturer is going to be aware of which is the better option based on pricing and durability and make the best tool for the intended job. The exception is when either plastic or metal sells better due to preconceived notions. Such a concept generally has more to do with home appliances and tools than laboratory equipment, as people with proper training through school or work are likely to understand how and why one material works and is better suited for their use.

Production Time

Plastics generally take less time to turn into final products once the initial setup is in place. That means custom sizes and accessories can be produced and delivered according to the needs of a lab, and replacement parts are likely to be more available when equipment needs maintenance. The manufacturing equipment for plastics tends to be computerized, it take the time of an engineer to pull up the proper program files and perhaps adjust it for specific needs, then plug that file into the production equipment. Metals, on the other hand, often have to be bent or shaped by hand, or at the least require manual setting of machinery to produce the final piece.


Travellers returning to England from Croatia, Hong Kong or Taiwan will not have to quarantine as the countries are due to be moved into the so-called Covid green list for travel, reports in the UK stated on Wednesday.

Until now Croatia has been ranked on the UK’s amber list, meaning that tourists returning home had to self-quarantine for ten days.

The government is expected to publish any changes to its travel rules later in the day and there has been speculation that Ibiza, Majorca and Menorca could be added to the Amber list. The Sun newspaper said Croatia would go on the green list, reports Reuters.

From next week, anyone who has been fully vaccinated will be able to return from an amber listed country without needing to quarantine, but younger people without both shots will need to quarantine at home.

A reporter for the Guardian said Indonesia, Myanmar and Sierra Leone were due to be added to the red list, meaning anyone returning from those countries would need to quarantine in a hotel.


The Dubrovnik-Neretva County, Administrative Department for Environmental Protection, Property-Legal and Communal Affairs, in accordance with the decree on the quality of bathing sea, warns the public that on the beach of Hotel Dubrovnik President in Dubrovnik there was short-term marine pollution of faecal origin.

According to the notification of the Public Health Institute of Dubrovnik-Neretva County from July 14, 2021, during the fifth examination of sea quality according to the program of determining the quality of the sea on the beaches of Dubrovnik-Neretva County in 2021, it was found that the results of sea analysis Dubrovnik President in Dubrovnik, sampled on July 12, exceed the limit values for the microbiological indicator Escherichia coli.

In accordance with the decree on the quality of bathing water sampling of the sea will be repeated until the cessation of pollution. The pollution was reported to the Environmental Protection Inspectorate and other competent inspections.

Since the sea sample on the beach on the beach of the Hotel Dubrovnik President does not meet the requirements of the regulation due to the contamination of faecal origin, bathing is not recommended until further notice.


In the last 24 hours, 155 new cases of Covid-19 virus infection were recorded, and the number of active cases in Croatia today is 595.

Among them, 111 people are in hospital, of which 8 are on ventilators.

Unfortunately, a further 2 people passed away in the past 24 hours.

Since February 25, 2020, when the first case of infection was recorded in Croatia, a total of 361,079 people have been infected with the new coronavirus, of which 8,233 have died, a total of 352,251 people have recovered, of which 54 in the last 24 hours.

There are currently 3,939 people in self-isolation.

To date, a total of 2,201,991 people have been tested, of which 3,965 in the last 24 hours.

As of 13 July, 1,562,081 people had been vaccinated with at least one dose, of which 1,317,827 people had been vaccinated with two doses.

In the last 24 hours, eight new cases of coronavirus infection have been recorded in the Dubrovnik-Neretva County.

These are five males and three females, all from Dubrovnik.

Eight people were cured - two each from Dubrovnik and Ploče, and one each from Konavle, Lastovo, Metković and Ston.

In the last 24 hours, 330 samples were processed, and since the beginning of the pandemic, a total of 89,850 samples have been analysed.

Three people tested positive for coronavirus were hospitalized in the Dubrovnik General Hospital.

There are 271 people in self-isolation, and in the last 24 hours, four violations of the self-isolation measure were recorded, three of which were at the border.


From 19 July, British citizens will be able to travel abroad and will no longer have to go into compulsory self-isolation when they return to the country from amber ranked countries.

The third largest airline in the UK, Jet2, has been introducing as many as nine routes to Croatian airports since the end of July. This is a direct consequence of the announced easing of restrictive measures in the UK (as of 19 July). Namely, since the mentioned date, Jet2 is re-introducing almost 40 lines to popular tourist destinations in Greece, Italy and Croatia, writes the portal Croatian Aviation, and reports Jutarnji list.

After the announcement of the abolition of strict measures, the company immediately reacted and opened a reservation on a number of routes, and in just a few days many flights were sold out, which only confirms the thesis that passengers are eager to travel and most are prevented only by restrictive measures.

Given that Croatia is currently on the list that guarantees British tourists return to the country without going into self-isolation, the company confirms that the interest in holidays in our country since the end of July is extremely high.

Jet2, the third largest company in the country (after British Airways and EasyJet) connects the UK with a number of leisure destinations. Additionally, through its sister company Jet2 Holidays, the company offers holiday arrangements (including flights) abroad, while also offering destinations in Croatia.
